| ○ | ○ | Article | Carbon-based adsorbents as proficient tools for the removal of heavy metals from aqueous solution: A state of art-review emphasizing recent progress and prospects | Carbon-centric adsorbents (CCA) are diverse forms, from simple biochar (BC) to graphene derivatives, carbon nanotubes (CNTs), and activated carbon (AC), which have been vastly explored for their removal of a plethora of pollutants, including heavy metals (HM). The prominent features of CCA are their operational attributes like extensive surface area, the occurrence of flexible surface functional groups, etc. This work offers a comprehensive examination of contemporary research on CCA for their superior metal removal aptitude and performances in simulated solutions and wastewater flows; via portraying the recent research advances as an outlook on the appliances of CACs for heavy metal adsorption for removal via distinct forms like AC, BC, Graphene oxide (GO), and CNTs. The bibliometric analysis tool was employed to highlight the number of documents, country-wise contribution, and co-occurrence mapping based on the Scopus database. The coverage of research works in this review is limited to the last 5 years (2017-2021) to highlight recent progress and prospects in using CCAs such as AC, BC, GO, and CNTs to remove HM from aqueous media, which makes the review unique. Besides an overview of the common mechanisms of CACs, the future scope of CAC, especially towards HM mitigation, is also discussed in this review. This review endorses that further efforts should be commenced to enhance the repertory of CCAs that effectively eliminate multiple targeted metals in both simulated and real wastewater. | Mahesh, Narayanan; Balakumar, Srinivasan; Shyamalagowri, Shanmugasundaram; Manjunathan, Jagadeesan; Pavithra, M.

| ○ | ○ | Article | Cytogenotoxicity assessment in Allium cepa roots exposed to methyl orange treated with Oedogonium subplagiostomum AP1 | The present study is an attempt to assess the cytogenotoxic effect of untreated and methyl orange treated with Oedogonium subplagiostomum AP1 on Allium cepa roots. On the fifth day, root growth, root length, mitotic index, mitotic inhibition/depression, and chromosomal abnormalities were measured in root cells of Allium cepa subjected to untreated and treated methyl orange dye solutions. Roots exposed to treated dye solution exhibited maximum root growth, root length and mitotic index, whereas roots exposed to untreated dye solution had the most mitotic inhibition and chromosomal abnormalities. Allium cepa exposed to untreated dye solution revealed chromosomal aberrations such as disoriented and abnormal chromosome grouping, vagrant and laggard chromosomes, chromosomal loss, sticky chain and disturbed metaphase, pulverised and disturbed anaphase, chromosomal displacement in anaphase, abnormal telophase, and chromosomal bridge at telophase, spindle disturbances and binucleate cells. The comet test was used to quantify DNA damage in the root cells of A. cepa subjected to untreated and treated methyl orange solutions in terms of tail DNA (percent) and tail length. The results concluded that A. cepa exposed to methyl orange induced DNA damage whereas meager damage was noted in the treated dye solution. As a result, the research can be used as a biomarker to detect the genotoxic effects of textile dyes on biota. | Alaguprathana, M.; Poonkothai, M.; Al-Ansari, Mysoon M.; Al-Humaid, Latifah; Kim, Woong | Adhiyaman Arts & Sci Coll Women, Dept Zool, Uthangarai 635207, Tamil Nadu, India; Avinashilingam Inst Home Sci & Higher Educ Women, Dept Zool, Coimbatore 641043, Tamil Nadu, India; King Saud Univ, Coll Sci, Dept Bot & Microbiol, Riyadh 11451, Saudi Arabia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Alaguprathana, Maruthanayagam/MEP-4664-2025; ALhumaid, Latifah/IZE-8542-2023; Al-Ansari, Mysoon/K-1915-2013 | 57221465734; 10538852200; 55266071800; 57207306888; 55581636400 | poonkothaii_zoo@avinuty.ac.in;elshine@knu.ac.kr; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 213 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 1.44 | 2025-06-25 | 19 | 19 | Allium cepa; Chromosomal aberrations; Comet assay; Mitotic index | WASTE-WATER; GENOTOXICITY; L.; CELLS; SOIL; DYE; CYTOTOXICITY; MERISTEM; ASSAY; DECOLORIZATION | Allium cepa; Chromosomal aberrations; Comet assay; Mitotic index | Allium; Azo Compounds; Chromosome Aberrations; DNA Damage; Mitotic Index; Onions; Plant Roots; acetic acid; alcohol; deoxyribonucleoprotein; distilled water; DNA; DNA topoisomerase (ATP hydrolysing); dye; methyl orange; nucleic acid; nucleoprotein; azo compound; methyl orange; bioassay; biomarker; cell; character displacement; chromosome; displacement; DNA; dye; inhibition; toxicity; anaphase; Article; chromosome; chromosome aberration; chromosome loss; clinical assessment; comet assay; controlled study; cytogenotoxicity; cytotoxicity; DNA damage; genotoxicity; green alga; metaphase; mitosis index; mitosis inhibition; nonhuman; Oedogonium subplagiostomum; onion; plant root; root cell; root growth; root length; sticky chain; telophase; water pollution; water supply; Allium; genetics; plant root | English | 2022 | 2022-10 | 10.1016/j.envres.2022.113612 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Degradation of phenol using Fe(II)-activated CaO2: effect of ball-milled activated carbon (ACBM) addition | In-situ chemical oxidation (ISCO) based on peroxide activation is one of the most promising technologies for removing organic contaminants from natural groundwater (NGW). However, use of the most common form of hydrogen peroxide (H2O2) is limited owing to its significantly rapid reaction rate and heat generation. Therefore, in the present study, the activation of calcium peroxide (CaO2), a slow H2O2 releasing agent, by Fe(II) was proposed (CaO2/Fe(II)), and the phenol degradation mechanisms and feasibility of NGW remediation were investigated. The optimum molar ratio of [phenol]/[CaO2]/[Fe(II)] (phenol = 0.5 mM) was 1/10/10, resulting in 87.0-92.5% phenol removal within 120 mM under a broad initial pH range of 3-9. HCO3-, PO43-, and humic acid significantly inhibited degradation, whereas the effects of Cl-, NO3-, and SO42- were negligible. Reactive oxygen species (ROS) were identified based on the results of phenol degradation in the presence of scavengers and electron spin resonance (ESR) spectroscopy, which demonstrated that O-1(2) played the dominant role, supported by center dot OH, in CaO2/Fe(II). Phenol removal in NGW (67.81%) was less than that in distilled and deionized water (DIW, 92.5%) at a [phenol]/[CaO2]/[Fe(II)] ratio of 1/10/10. However, phenol removal was significantly improved (similar to 100%) by increasing the CaO2 and Fe(II) doses to 1/20/20-40. Furthermore, when 125-250 mg L-1 of ball-milled activated carbon (AC(BM)) was added (CaO2/Fe(II)-AC(BM)), phenol removal was enhanced from 67.81% to 90.94-100% in the NGW. CaO2/Fe(II)-AC(BM) exhibited higher total organic carbon (TOC) removal than CaO2/Fe(II). In addition, no notable by-products were detected using CaO2/Fe(II)-AC(BM), whereas the polymerisation products of hydroxylated and/or ring-cleaved compounds, that is, aconitic acid, gallocatechin, and 10-hydroxyaloin, were found in the reaction with CaO2/Fe(II). These results strongly suggest that CaO2/Fe (II)-AC(BM) is highly promising for groundwater remediation, minimizing degradation byproducts and the adverse effects caused by the NGW components. | Al Masud, Md Abdullah; Kim, Do Gun; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Sunchon Natl Univ, Dept Environm Engn, Sunchon 57922, Jeonranam Do, South Korea | ; Masud, Md Abdullah Al/JEF-1055-2023 | 57542255300; 36623899900; 23019870800 | dgkim@scnu.ac.kr;wshin@knu.ac.kr; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 214 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 1.82 | 2025-06-25 | 23 | 24 | Calcium peroxide; Ball-milled activated carbon; Groundwater; Oxidation; Phenol removal; Reactive oxygen species (ROS) | HETEROGENEOUS FENTON OXIDATION; CALCIUM PEROXIDE; PERSULFATE OXIDATION; AQUEOUS-SOLUTION; BISPHENOL-A; OXYGEN; WATER; TRICHLOROETHYLENE; REMEDIATION; SOIL | Ball-milled activated carbon; Calcium peroxide; Groundwater; Oxidation; Phenol removal; Reactive oxygen species (ROS) | Charcoal; Ferrous Compounds; Hydrogen Peroxide; Oxidation-Reduction; Phenol; Phenols; Water Pollutants, Chemical; 10 hydroxyaloin; aconitic acid; activated carbon; calcium; calcium peroxide; deionized water; ferrous ion; gallocatechin; ground water; humic acid; hydrogen peroxide; peroxide; phenol; reactive oxygen metabolite; unclassified drug; charcoal; ferrous ion; phenol derivative; activated carbon; degradation; groundwater pollution; humic acid; hydrogen peroxide; oxidation; phenol; pollutant removal; reaction rate; reactive oxygen species; Article; bioremediation; chemical reaction; controlled study; degradation kinetics; electron spin resonance; oxidation; pH; reaction analysis; reaction temperature; total organic carbon; chemistry; oxidation reduction reaction; water pollutant | English | 2022 | 2022-11 | 10.1016/j.envres.2022.113882 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Early postnatal serotonin modulation prevents adult-stage deficits in Arid1b-deficient mice through synaptic transcriptional reprogramming | ARID1B is a chromatin remodeler associated with autism spectrum disorders. Here the authors demonstrate that early postnatal serotonin modulation prevents adult stage deficits in Arid1b-deficient mice through synaptic transcriptional reprogramming. Autism spectrum disorder is characterized by early postnatal symptoms, although little is known about the mechanistic deviations that produce them and whether correcting them has long-lasting preventive effects on adult-stage deficits. ARID1B, a chromatin remodeler implicated in neurodevelopmental disorders, including autism spectrum disorder, exhibits strong embryonic- and early postnatal-stage expression. We report here that Arid1b-happloinsufficient (Arid1b(+/-)) mice display autistic-like behaviors at juvenile and adult stages accompanied by persistent decreases in excitatory synaptic density and transmission. Chronic treatment of Arid1b(+/-) mice with fluoxetine, a selective serotonin-reuptake inhibitor, during the first three postnatal weeks prevents synaptic and behavioral deficits in adults. Mechanistically, these rescues accompany transcriptomic changes, including upregulation of FMRP targets and normalization of HDAC4/MEF2A-related transcriptional regulation of the synaptic proteins, SynGAP1 and Arc. These results suggest that chronic modulation of serotonergic receptors during critical early postnatal periods prevents synaptic and behavioral deficits in adult Arid1b(+/-) mice through transcriptional reprogramming. | Kim, Hyosang; Kim, Doyoun; Cho, Yisul; Kim, Kyungdeok; Roh, Junyeop Daniel; Kim, Yangsik; Yang, Esther; Kim, Seong Soon; Ahn, Sunjoo; Kim, Hyun; Kang, Hyojin; Bae, Yongchul; Kim, Eunjoon | Korea Adv Inst Sci & Technol KAIST, Dept Biol Sci, Daejeon 34141, South Korea; Inst Basic Sci IBS, Ctr Synapt Brain Dysfunct, Daejeon 34141, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Anat & Neurobiol, Daegu 41940, South Korea; Korea Adv Inst Sci & Technol KAIST, Grad Sch Biomed Engn, Daejeon 34141, South Korea; Korea Univ, Coll Med, Dept Anat, Seoul 02841, South Korea; Korea Univ, Coll Med, Div Brain Korea 21, Biomed Sci, Seoul 02841, South Korea; Korea Res Inst Chem Technol KRICT, Therapeut & Biotechnol Div, Daejeon 34114, South Korea; Korea Inst Sci & Technol Informat, Div Natl Supercomp, Daejeon 34141, South Korea | Kim, Seong Soon/IZE-2538-2023; Kim, Eunjoon/C-1566-2011; Kim, Do Hyun/AAA-2792-2021; Kim, Yangsik/ABC-7551-2020; Kim, Ho/G-2712-2011 | 57192369940; 55868319700; 23979595700; 56643307400; 56973410500; 57189378455; 57194107730; 57194944619; 56714494700; 55663909700; 57203522541; 56377838800; 57203240554 | ycbae@knu.ac.kr;kime@kaist.ac.kr; | NATURE COMMUNICATIONS | NAT COMMUN | 2041-1723 | 13 | 1 | SCIE | MULTIDISCIPLINARY SCIENCES | 2022 | 16.6 | 7.5 | 0.69 | 2025-06-25 | 11 | 10 | CHROMATIN-REMODELING COMPLEX; BETA-CATENIN; PLASTICITY; ARID1B; HDAC4; MUTATIONS; GENES; HAPLOINSUFFICIENCY; PHOSPHORYLATION; FLUOXETINE | Animals; Autism Spectrum Disorder; Autistic Disorder; Fluoxetine; Mice; ras GTPase-Activating Proteins; Serotonin; Transcription Factors; AT rich interaction domain 1B; fluoxetine; fragile X mental retardation protein; histone deacetylase 4; protein; protein mef2a; protein syngap1; serotonin; serotonin receptor; unclassified drug; Arid1b protein, mouse; fluoxetine; guanosine triphosphatase activating protein; serotonin; Syngap1 protein, mouse; transcription factor; autism; gene expression; inhibitor; juvenile; nervous system disorder; protein; rodent; symptom; animal cell; animal experiment; animal model; animal tissue; Article; autism; behavior disorder; compulsion; controlled study; drug mechanism; embryo; gene expression; genetic transcription; haploinsufficiency; long term care; male; mental disease; mouse; neuroprotection; nonhuman; nuclear reprogramming; perinatal period; phenotype; postsynaptic density; prefrontal cortex; receptor upregulation; serotonin brain level; serotonin uptake; serotoninergic nerve cell; social behavior; synapse; synaptic transmission; transcription regulation; transcriptomics; animal | English | 2022 | 2022-08-27 | 10.1038/s41467-022-32748-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Elucidation the influence of design variables on coagulation-flocculation mechanisms in the lab-scale bio-coagulation on toxic industrial effluent treatment | Bio-coagulants are environmentally friendly substances that have shown potential in removing organic and inorganic contaminants from wastewater from the Imitation Paint Industry. Under the optimized conditions, the use of the three bio-coagulants (of plant origin), Strychnos potatorum, Cactus opuntia and Portunus sanguinolentus (crab) shell (of animal origin) were evaluated, and their removal mechanism was based on kinetic models and adsorption isotherms. The error analysis method was used to find the best isotherm fit. In addition, the kinetic model parameters showed the absence of chemisorption and confirmed the existence of pore diffusion. The interaction between coagulant and pollutant, the type, homogeneity and intensity of the coagulation process, the pollutant absorption capacity of the coagulant were evaluated with the aid of the adsorption isotherm models. From the Pseudo first-order kinetic model an equilibrium pollutant uptake (mg/g) was marked as 598, 554 and 597 for Strychnos potatorum, Cactus opuntia and Portunus sanguinolentus respectively. The better affinity between the pollutants and the bio coagulants were observed through the lower values of Langmuir isotherm constant kL. The adsorption intensity from Freundlich model (nF) were ranged between 1 and 10 for all the listed coagulants, which revealed the physisorption behavior and heterogeneous mechanism of removal. With these results, it would be possible to conduct scale-up studies to adopt the process for practical systems. | Vishali, S.; Mullai, P.; Mahboob, Shahid; Al-Ghanim, K.; Sivasankar, Annamalai | SRM Inst Sci & Technol, Coll Engn & Technol, Dept Chem Engn, Chennai 603203, Tamil Nadu, India; Annamalai Univ, Dept Chem Engn, Chidambaram 608002, India; King Saud Univ, Coll Sci, Dept Zool, POB 2455, Riyadh 11451, Saudi Arabia; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | Rana, Shahid/P-1131-2014; Annamalai, Sivasankar/G-7823-2016; S, Vishali/ABE-7685-2021; Mahboob Rana, Shahid/P-1131-2014; P, Mullai/HZI-7486-2023 | 16687217100; 8646800900; 27167500800; 25632011700; 56388546200 | meet.vishali@gmail.com; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 212 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 0.76 | 2025-06-25 | 9 | 10 | Adsorption isotherms; Bio-coagulants; Coagulation; Kinetic model; Paint industry effluent | ADSORPTION-ISOTHERM; KINETICS; PAINT; THERMODYNAMICS; REMOVAL | Adsorption isotherms; Bio-coagulants; Coagulation; Kinetic model; Paint industry effluent | Adsorption; Animals; Flocculation; Hydrogen-Ion Concentration; Kinetics; Waste Water; Water Pollutants, Chemical; Water Purification; coagulating agent; industrial effluent; industrial toxic substance; absorption; adsorption; coagulation; effluent; equilibrium; flocculation; industrial waste; isotherm; numerical model; waste treatment; adsorption kinetics; analytical error; Article; Cactus opuntia; chemisorption; coagulation kinetics; controlled study; diffusion; effluent; flocculation; isotherm; kinetics; nonhuman; pH; physisorption; Portunus; Portunus sanguinolentus; rate constant; scale up; Strychnos; Strychnos potatorum; surface property; adsorption; animal; flocculation; kinetics; procedures; wastewater; water management; water pollutant | English | 2022 | 2022-09 | 10.1016/j.envres.2022.113224 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Emerging contaminants of high concern for the environment: Current trends and future research | Wastewater is contaminated water that must be treated before it may be transferred into other rivers and lakes in order to prevent further groundwater pollution. Over the last decade, research has been conducted on a wide variety of contaminants, but the emerging contaminants are those caused primarily by micropollutants, endocrine disruptors (EDs), pesticides, pharmaceuticals, hormones, and toxins, as well as industrially-related synthetic dyes and dye-containing hazardous pollutants. Most emerging pollutants did not have established guidelines, but even at low concentrations they could have harmful effects on humans and aquatic organisms. In order to combat the above ecological threats, huge efforts have been done with a view to boosting the effectiveness of remediation procedures or developing new techniques for the detection, quantification and efficiency of the samples. The increase of interest in biotechnology and environmental engineering gives an opportunity for the development of more innovative ways to water treatment remediation. The purpose of this article is to provide an overview of emerging sources of contaminants, detection technologies, and treatment strategies. The goal of this review is to evaluate adsorption as a method for treating emerging pollutants, as well as sophisticated and cost-effective approaches for treating emerging contaminants. | Khan, Shamshad; Naushad, Mu; Govarthanan, Muthusamy; Iqbal, Jibran; Alfadul, Sulaiman M. | Neijiang Normal Univ, Sch Geog & Resources Sci, Neijiang 641100, Peoples R China; King Saud Univ, Coll Sci, Dept Chem, Adv Mat Res Chair, Riyadh 11451, Saudi Arabia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Zayed Univ, Coll Nat & Hlth Sci, POB 144534, Abu Dhabi, U Arab Emirates; King Abdulaziz City Sci & Technol, Riyadh 11442, Saudi Arabia | ; Iqbal, Jibran/I-9140-2019; khan, shamshad/P-9800-2018; NAUSHAD, M./D-8006-2014; Govarthanan, Muthusamy/C-1491-2014; Muthusamy, Govarthanan/C-1491-2014; NAUSHAD, M./D-8006-2014; Alfadul, Sulaiman/T-9665-2019 | 56079487000; 13105221300; 54881927600; 36173307200; 36169228900 | shamshadkhan768@njtc.edu.cn;mnaushad@ksu.edu.sa; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 207 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 36.34 | 2025-06-25 | 441 | 489 | Emerging contaminants; Removal techniques; Environmental pollution; Wastewater | PERSONAL CARE PRODUCTS; WASTE-WATER TREATMENT; POLYCYCLIC AROMATIC-HYDROCARBONS; BIO-CATALYTIC PERFORMANCE; SOLID-PHASE EXTRACTION; TREATMENT PLANTS; ACTIVATED CARBON; HORSERADISH-PEROXIDASE; DRINKING-WATER; ENDOCRINE DISRUPTORS | Emerging contaminants; Environmental pollution; Removal techniques; Wastewater | Environmental Monitoring; Groundwater; Humans; Waste Water; Water Pollutants, Chemical; Water Purification; ground water; biotechnology; groundwater; remediation; wastewater; wastewater treatment; water pollution; water treatment; adsorption; article; biotechnology; human; wastewater; water treatment; environmental monitoring; procedures; wastewater; water management; water pollutant | English | 2022 | 2022-05-01 | 10.1016/j.envres.2021.112609 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | ESRP1-regulated isoform switching of LRRFIP2 determines metastasis of gastric cancer | Although accumulating evidence indicates that alternative splicing is aberrantly altered in many cancers, the functional mechanism remains to be elucidated. Here, we show that epithelial and mesenchymal isoform switches of leucine-rich repeat Fli-I-interacting protein 2 (LRRFIP2) regulated by epithelial splicing regulatory protein 1 (ESRP1) correlate with metastatic potential of gastric cancer cells. We found that expression of the splicing variants of LRRFIP2 was closely correlated with that of ESRP1. Surprisingly, ectopic expression of the mesenchymal isoform of LRRFIP2 (variant 3) dramatically increased liver metastasis of gastric cancer cells, whereas deletion of exon 7 of LRRFIP2 by the CRISPR/Cas9 system caused an isoform switch, leading to marked suppression of liver metastasis. Mechanistically, the epithelial LRRFIP2 isoform (variant 2) inhibited the oncogenic function of coactivator-associated arginine methyltransferase 1 (CARM1) through interaction. Taken together, our data reveals a mechanism of LRRFIP2 isoform switches in gastric cancer with important implication for cancer metastasis. ESRP1 is reported to regulate the alternative splicing of some genes involved in epithelial-mesenchymal transition. Here the authors show that LRRFIP2 is a target of ESRP1 and that two spliced variants of LRRFIP2 have opposing functions in gastric cancer metastasis | Lee, Jihee; Pang, Kyoungwha; Kim, Junil; Hong, Eunji; Lee, Jeeyun; Cho, Hee Jin; Park, Jinah; Son, Minjung; Park, Sihyun; Lee, Minjung; Ooshima, Akira; Park, Kyung-Soon; Yang, Han-Kwang; Yang, Kyung-Min; Kim, Seong-Jin | GILO Fdn, GILO Inst, Seoul 06668, South Korea; CHA Univ, Coll Life Sci, Dept Biomed Sci, Seongnam 13488, Gyeonggi Do, South Korea; Soongsil Univ, Sch Syst Biomed Sci, Seoul 06978, South Korea; Sungkyunkwan Univ, Coll Life Sci, Dept Biomed Sci, Suwon 16419, Gyeonggi Do, South Korea; Sungkyunkwan Univ, Dept Med, Div Hematol Oncol, Samsung Med Ctr,Sch Med, Seoul 06351, South Korea; Kyungpook Natl Univ, Dept Biomed Convergence Sci & Technol, Daegu 41566, South Korea; Samsung Med Ctr, Innovat Therapeut Res Ctr, Precis Med Res Inst, Seoul 06531, South Korea; Medpacto Inc, Seoul 06668, South Korea; Seoul Natl Univ Hosp, Dept Surg, Seoul 03080, South Korea; Seoul Natl Univ, Canc Res Inst, Seoul 03080, South Korea | Yang, Kyungmin/KOC-1513-2024; Kim, Jeong-Rae/Q-5163-2019; Yang, Han-Kwang/J-2767-2012; Kim, Seong/AAV-1869-2020; Lee, Jee/C-9646-2011; Pang, Kyoungwha/JGE-1771-2023 | 57196418382; 57197341687; 24448569700; 57196415411; 55899617000; 55937716400; 55249456800; 57464789500; 57942264700; 57204657988; 8052672600; 57197852593; 7406557280; 56463268800; 57070732900 | jasonsjkim@gilo.or.kr; | NATURE COMMUNICATIONS | NAT COMMUN | 2041-1723 | 13 | 1 | SCIE | MULTIDISCIPLINARY SCIENCES | 2022 | 16.6 | 7.5 | 1.23 | 2025-06-25 | 21 | 18 | SPLICING REGULATORY PROTEIN-1; NUCLEAR RECEPTOR COACTIVATOR; LEUCINE-RICH REPEAT; FLIGHTLESS-I; WEB SERVER; EXPRESSION; BREAST; TRANSCRIPTION; METHYLATION; GENOME | Adaptor Proteins, Signal Transducing; Alternative Splicing; Cell Line, Tumor; Epithelial-Mesenchymal Transition; Humans; Liver Neoplasms; Protein Isoforms; RNA-Binding Proteins; Stomach Neoplasms; Transcription Factors; axin2 protein; binding protein; ccne1 protein; coactivator associated arginine methyltransferase 1; collagen type 5 alpha 2; complementary DNA; cyclin dependent kinase 6; epithelial splicing regulatory protein 1; ezm 2302; gadd45a protein; guide RNA; leucine rich repeat fli i interacting protein 2; leucine rich repeat protein; loxl2 protein; messenger RNA; methylcellulose; protein arginine methyltransferase; protein inhibitor; regulator protein; RNA; sema3c protein; serpine1 protein; transcription factor Fli 1; transcriptome; unclassified drug; ESRP1 protein, human; isoprotein; LRRFIP2 protein, human; RNA binding protein; signal transducing adaptor protein; transcription factor; cancer; cell; gene expression; inhibition; inhibitor; protein; alternative RNA splicing; animal experiment; animal model; Article; carcinogenesis; cell proliferation; chromatin immunoprecipitation; clinical article; clinical outcome; controlled study; CRISPR-CAS9 system; ectopic expression; epithelial mesenchymal transition; exon; gastric cancer cell line; gene deletion; gene expression level; gene ontology; gene overexpression; gene switching; histone methylation; human; human cell; human tissue; liver metastasis; male; mouse; nonhuman; protein protein interaction; regulatory mechanism; RNA immunoprecipitation; RNA sequencing; stomach cancer; stomach tissue; genetics; liver tumor; metabolism; stomach tumor; tumor cell line | English | 2022 | 2022-10-28 | 10.1038/s41467-022-33786-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Fabrication of Salvinia-inspired surfaces for hydrodynamic drag reduction by capillary-force-induced clustering | For decades, bioinspired functional materials have been attracting the interest of many researchers for their remarkable characteristics. In particular, some plant leaves are well known for their inherent superhydrophobic nature. Salvinia molesta, a free-floating aquatic fern, has egg-beater-shaped hierarchical trichomes on its surface of leaves. Due to the unique structure and complex wettability of the hairs, this plant has the ability to maintain a stable thick air layer upon the structure when it is submerged underwater. Often referred to as the "Salvinia Effect," this property is expected to be suitable for use in hydrodynamic drag reduction. However, due to the complex shape of the trichome, currently applied fabrication methods are using a three-dimensional printing system, which is not applicable to mass production because of its severely limited productivity. In this work, artificial Salvinia leaf inspired by S. molesta was fabricated using a conventional soft lithography method assisted with capillary-force-induced clustering of micropillar array. The fabrication method suggested in this work proposes a promising strategy for the manufacturing of Salvinia-inspired hydrodynamic drag reduction surfaces. Salvinia molesta plant has the ability to maintain a stable air layer when submerged underwater due to its specific form. The authors propose here a soft lithography fabrication method of artificial Salvinia leaf assisted with capillary-force induced clustering of micropillar array, for hydrodynamic drag reduction. | Kim, Minsu; Yoo, Seunghoon; Jeong, Hoon Eui; Kwak, Moon Kyu | Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea; Ulsan Natl Inst Sci & Technol UNIST, Dept Mech Engn, Ulsan 44919, South Korea | ; Kwak, Moon/AGQ-6058-2022 | 57212315616; 57871736100; 35490647000; 57203947984 | mkkwak@knu.ac.kr; | NATURE COMMUNICATIONS | NAT COMMUN | 2041-1723 | 13 | 1 | SCIE | MULTIDISCIPLINARY SCIENCES | 2022 | 16.6 | 7.5 | 3.08 | 2025-06-25 | 47 | 45 | MICROPILLAR ARRAYS; ADHESION; STABILITY | article; hair; hydrodynamics; plant leaf; productivity; three dimensional printing; trichome; wettability | English | 2022 | 2022-09-02 | 10.1038/s41467-022-32919-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Graphene materials: Armor against nosocomial infections and biofilm formation-A review | Graphene has revolutionized the field of energy and storage sectors. Out of the total number of nosocomial infections diagnosed all around the world, the majority of the cases (around 70%) are found to be due to the medical device or assistance utilized while treating the patient. Combating these diseases is vital as they cause a nuisance to the patients and medical practitioners. Coatings of graphene and its derivatives hold the key to the formation of special surfaces that can rupture microbial cells using their sharp edges, ultimately leading to nuclear and cellular fragmentation. Their incorporation as a whole or as a part in the hospital apparel and the medical device has aided medical practitioners to combat many nosocomial diseases. Graphene is found to be highly virulent with broad-spectrum antimicrobial activity against nosocomial strains and biofilm formation. Their alternate mode of action like trapping and charge transfer has also been discussed well in the present review. The various combinational forms of graphene with its conjugates as a suitable agent to combat nosocomial infections and a potential coating for newer challenges like COVID-19 infections has also been assessed in the current study. Efficiency of graphene sheets has been found to be around 89% with a reaction time as less as 3 h. Polymers with graphene seem to have a higher potency against biofilm formation. When combined with graphene oxide, silver nanoparticles provide 99% activity against nosocomial pathogens. In conclusion, this review would be a guiding light for scientists working with graphene-based coatings to unfold the potentials of this marvelous commodity to tackle the present and future pandemics to come. | Dey, Nibedita; Vickram, Sundaram; Thanigaivel, Sundaram; Kamatchi, Chandrasekaran; Subbaiya, Ramasamy; Karmegam, Natchimuthu; Govarthanan, Muthusamy | Saveetha Inst Med & Tech Sci, Saveetha Sch Engn, Dept Biotechnol, Chennai 602105, Tamil Nadu, India; SRM Inst Sci & Technol, Fac Sci & Humanities, Dept Biotechnol, Chennai 603203, Tamil Nadu, India; Oxford Coll Sci, Dept Biotechnol, Bengaluru 560102, Karnataka, India; Copperbelt Univ, Sch Math & Nat Sci, Dept Biol Sci, Jambo Dr,POB, Kitwe 21692, Zambia; Govt Arts Coll Autonomous, Dept Bot, Salem 636007, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | ; Natchimuthu, Karmegam/J-4745-2019; S, Vickram/ABG-9459-2020; dey, nibedita/AAG-6776-2021; Karmegam, Natchimuthu/J-4745-2019; Govarthanan, Muthusamy/C-1491-2014; Subbaiya, R/AAR-2948-2021; Muthusamy, Govarthanan/C-1491-2014 | 57216549253; 55257689800; 55624925900; 57207471093; 55263515700; 6506043230; 54881927600 | kanishkarmegam@gmail.com;gova.muthu@gmail.om; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 214 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 3.95 | 2025-06-25 | 20 | 52 | Cellular disruption; Graphene nanomaterials; Hospital acquired diseases; Nosocomial infections; Surface coatings | MEDIATED ANTIBACTERIAL ACTIVITY; SILVER NANOPARTICLES; ANTIMICROBIAL ACTIVITY; BROAD-SPECTRUM; PSEUDOMONAS-AERUGINOSA; STAPHYLOCOCCUS-AUREUS; RESISTANT-BACTERIA; OXIDE; COPPER; NANOTECHNOLOGY | Cellular disruption; Graphene nanomaterials; Hospital acquired diseases; Nosocomial infections; Surface coatings | Anti-Bacterial Agents; Biofilms; COVID-19; Cross Infection; Graphite; Humans; Metal Nanoparticles; Silver; graphene; polymer; silver nanoparticle; antiinfective agent; graphite; metal nanoparticle; silver; antimicrobial activity; biofilm; energy storage; infectious disease; antimicrobial activity; Article; biofilm; coating (procedure); coronavirus disease 2019; hospital infection; human; nonhuman; physician; Severe acute respiratory syndrome coronavirus 2; surface property; synthesis; cross infection | English | 2022 | 2022-11 | 10.1016/j.envres.2022.113867 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Hypervalency in amorphous chalcogenides | The concept of hypervalency emerged as a notion for chemical bonding in molecules to explain the atomic coordination in hypervalent molecules that violates the electron-octet rule. Despite its significance, however, hypervalency in condensed phases, such as amorphous solids, remains largely unexplored. Using ab initio molecular-dynamics simulations, we report here the underlying principles of hypervalency in amorphous chalcogenide materials, in terms of the behaviour of hypervalent structural units, and its implicit relationship with material properties. The origin of a material-dependent tendency towards hypervalency is made evident with the multi-centre hyperbonding model, from which its relationship to abnormally large Born effective charges is also unambiguously revealed. The hyperbonding model is here extended to include interactions with cation s(2) lone pairs (LPs); such deep-lying LPs can also play a significant role in determining the properties of these chalcogenide materials. The role of hypervalency constitutes an indispensable and important part of chemical interactions in amorphous and crystalline chalcogenide solids. The current study explores by ab-initio molecular dynamics simuations the concept of hypervalency in amorphous chalcogenide materials, from which a unified conceptual framework for understanding chemical bonding, microscopic structures, and structure-property relationships is established. | Lee, T.

| ○ | ○ | Article | Ice front retreat reconfigures meltwater-driven gyres modulating ocean heat delivery to an Antarctic ice shelf | Glacial melt can modify heat transport, and therefore ocean processes, associated with ice front retreat, as revealed by direct observations from the Pine Island Bay region of Antarctica. Pine Island Ice Shelf (PIIS) buttresses the Pine Island Glacier, the key contributor to sea-level rise. PIIS has thinned owing to ocean-driven melting, and its calving front has retreated, leading to buttressing loss. PIIS melting depends primarily on the thermocline variability in its front. Furthermore, local ocean circulation shifts adjust heat transport within Pine Island Bay (PIB), yet oceanic processes underlying the ice front retreat remain unclear. Here, we report a PIB double-gyre that moves with the PIIS calving front and hypothesise that it controls ocean heat input towards PIIS. Glacial melt generates cyclonic and anticyclonic gyres near and off PIIS, and meltwater outflows converge into the anticyclonic gyre with a deep-convex-downward thermocline. The double-gyre migrated eastward as the calving front retreated, placing the anticyclonic gyre over a shallow seafloor ridge, reducing the ocean heat input towards PIIS. Reconfigurations of meltwater-driven gyres associated with moving ice boundaries might be crucial in modulating ocean heat delivery to glacial ice. | Yoon, Seung-Tae; Lee, Won Sang; Nam, SungHyun; Lee, Choon-Ki; Yun, Sukyoung; Heywood, Karen; Boehme, Lars; Zheng, Yixi; Lee, Inhee; Choi, Yeon; Jenkins, Adrian; Jin, Emilia Kyung; Larter, Robert; Wellner, Julia; Dutrieux, Pierre; Bradley, Alexander T. | Kyungpook Natl Univ, Sch Earth Syst Sci, 80 Daehak Ro, Daegu 41566, South Korea; Korea Polar Res Inst, Div Glacial Environm Res, Incheon 21990, South Korea; Seoul Natl Univ, Sch Earth & Environm Sci, Res Inst Oceanog, Seoul 08826, South Korea; Univ East Anglia, Sch Environm Sci, Norwich NF4 7TJ, Norfolk, England; Univ St Andrews, Scottish Oceans Inst, St Andrews KY16 8LB, Fife, Scotland; Pusan Natl Univ, Dept Oceanog, Busan 46241, South Korea; Northumbria Univ, Dept Geog & Environm Sci, Newcastle Upon Tyne NE1 8ST, Tyne & Wear, England; British Antarctic Survey, Cambridge CB3 0ET, England; Univ Houston, Dept Earth & Atmospher Sci, Houston, TX 77004 USA | ; Dutrieux, Pierre/B-7568-2012; Lee, Inhee/AAK-7760-2021; Jenkins, Adrian/IUN-2406-2023; Bradley, Alex/GRO-6619-2022; Boehme, Lars/B-6567-2009; Heywood, Karen/L-1757-2016; Yoon, Seung-Tae/GXV-4573-2022; Nam, SungHyun/M-8610-2019 | 37015068400; 55713048700; 55415668000; 55771619400; 16679994900; 7003373288; 57203674675; 57418913700; 57417776600; 57224767165; 25723322400; 36836680100; 7003885261; 6701723886; 23980085900; 57206847149 | wonsang@kopri.re.kr;namsh@snu.ac.kr; | NATURE COMMUNICATIONS | NAT COMMUN | 2041-1723 | 13 | 1 | SCIE | MULTIDISCIPLINARY SCIENCES | 2022 | 16.6 | 7.5 | 1.17 | 2025-06-25 | 17 | 17 | PINE ISLAND GLACIER; SEA CONTINENTAL-SHELF; OCEANOGRAPHIC CONTROLS; CIRCULATION; VARIABILITY; SHEET; STABILITY; IMPACT; FATE; MELT | Antarctic Ice Sheet; Antarctica; Pine Island Bay; Pine Island Glacier; West Antarctica; gyre; ice field; ice retreat; ice shelf; iceberg calving; meltwater; sea level change; thermocline; Antarctica; article; glacier; heat; ice shelf; ocean circulation; thermocline | English | 2022 | 2022-01-13 | 10.1038/s41467-022-27968-8 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Large-gap insulating dimer ground state in monolayer IrTe2 | Monolayers of two-dimensional van der Waals materials exhibit novel electronic phases distinct from their bulk due to the symmetry breaking and reduced screening in the absence of the interlayer coupling. In this work, we combine angle-resolved photoemission spectroscopy and scanning tunneling microscopy/spectroscopy to demonstrate the emergence of a unique insulating 2 x 1 dimer ground state in monolayer 1T-IrTe2 that has a large band gap in contrast to the metallic bilayer-to-bulk forms of this material. First-principles calculations reveal that phonon and charge instabilities as well as local bond formation collectively enhance and stabilize a charge-ordered ground state. Our findings provide important insights into the subtle balance of interactions having similar energy scales that occurs in the absence of strong interlayer coupling, which offers new opportunities to engineer the properties of 2D monolayers. The interplay between reduced dimensionality and interactions in monolayer transition metal dichalcogenides has been of great research interest. Here the authors report an insulating dimer ground state in 1T-IrTe2, driven by the combined effect of the charge density wave instability and local atomic bond formation. | Hwang, Jinwoong; Kim, Kyoo; Zhang, Canxun; Zhu, Tiancong; Herbig, Charlotte; Kim, Sooran; Kim, Bongjae; Zhong, Yong; Salah, Mohamed; El-Desoky, Mohamed M.; Hwang, Choongyu; Shen, Zhi-Xun; Crommie, Michael F.; Mo, Sung-Kwan | Lawrence Berkeley Natl Lab, Adv Light Source, Berkeley, CA 94720 USA; Pusan Natl Univ, Dept Phys, Busan, South Korea; SLAC Natl Accelerator Lab, Stanford Inst Mat & Energy Sci, Menlo Pk, CA 94025 USA; Korea Atom Energy Res Inst, Daejeon, South Korea; Univ Calif Berkeley, Dept Phys, Berkeley, CA 94720 USA; Lawrence Berkeley Natl Lab, Mat Sci Div, Berkeley, CA USA; Univ Calif Berkeley, Kavli Energy NanoSci Inst, Berkeley, CA 94720 USA; Kyungpook Natl Univ, Dept Phys Educ, Daegu, South Korea; Kunsan Natl Univ, Dept Phys, Gunsan, South Korea; Stanford Univ, Dept Phys & Appl Phys, Geballe Lab Adv Mat, Stanford, CA 94305 USA; Suez Univ, Fac Sci, Phys Dept, Suez, Egypt | Zhu, Tiancong/J-4828-2017; Mo, Sung-Kwan/F-3489-2013; Salah, Mohamed/KYQ-4193-2024; Crommie, Michael/J-4824-2015; MIN, B.

| ○ | ○ | Article | MXsorption of mercury: Exceptional reductive behavior of titanium carbide/carbonitride MXenes | Two-dimensional (2D) transition metal carbides and nitrides (MXenes) have drawn considerable attention for application in the field of environmental remediation. In this study, we report the simultaneous reductive-adsorption behavior of Ti3CNTx for toxic metal ion Hg2+ ion in the aqueous phase. 2D Ti3CNTx and Ti3C2Tx MXene nanosheets were synthesized by exfoliation of Ti3AlCN and Ti3AlC2 MAX phases, respectively. Various characteristics analysis confirmed the successful fabrication of MAX phases and their exfoliation into MXenes. The fabricated MXene nanosheets were used to investigate their Hg2+ removal, Hg2+ intercalation, and surface interaction mechanism efficiencies. Both MXenes were found to adsorb and reduce a large amount of Hg2+. Analytical techniques such as X-ray powder diffraction, field emission transmission electron microscopy, zetapotential analyses, and X-ray photoelectron spectroscopy were used to investigate the material characteristics and structural changes after uptake of Hg2+. The quantitative investigation confirmed the interaction of bimetal and hydroxyl groups with Hg2+ using electrostatic interactions and adsorption-coupled reduction. In addition, both MXenes exhibited extraordinary Hg ion removal capabilities in terms of fast kinetics with an excellent distribution coefficient (KdHg) up to 1.36 x 10+9. Based on batch adsorption results, Ti3C2Tx and Ti3CNTx exhibited removal capacities of 5473.13 and 4606.04 mg/g, respectively, for Hg2+, which are higher than those of previous Hg adsorbents. | Shahzad, Asif; Rasool, Kashif; Iqbal, Jibran; Jang, Jiseon; Lim, Youngsu; Kim, Bolam; Oh, Jae-Min; Lee, Dae Sung | Dongguk Univ, Dept Energy & Mat Engn, Seoul 04620, South Korea; Hamad Bin Khalifa Univ, Qatar Fdn, Qatar Environm & Energy Res Inst, POB 5824, Doha, Qatar; Zayed Univ, Coll Nat & Hlth Sci, Abu Dhabi 144534, U Arab Emirates; Korea Radioact Waste Agcy, R&D Inst Radioact Wastes, 174 Gajeong Ro, Daejeon 34129, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | Rasool, Kashif/AAN-6671-2020; Iqbal, Jibran/I-9140-2019 | 57190382338; 28767865000; 36173307200; 56611137400; 57207112603; 57208922438; 7402155053; 55568524907 | jaemin.oh@dongguk.edu;daesung@knu.ac.kr; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 205 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 2.36 | 2025-06-25 | 30 | 31 | MXsorption; Titanium carbonitride; MXene; Hg reduction; Water decontamination | HEAVY-METAL IONS; AQUEOUS-SOLUTION; ORGANIC FRAMEWORKS; ACTIVATED CARBON; REMOVAL; ADSORPTION; EFFICIENT; CAPTURE; POLYMERS; WATER | Hg reduction; MXene; MXsorption; Titanium carbonitride; Water decontamination | aluminum derivative; hydroxyl group; mercury; metal ion; nanosheet; titanium carbide; adsorption; chemical compound; detection method; inorganic compound; kinetics; mercury (element); reaction kinetics; resorption; sorption; transition element; adsorption; adsorption kinetics; analytic method; Article; comparative study; controlled study; decontamination; degradation kinetics; field emission; isotherm; partition coefficient; pH; reduction (chemistry); scanning electron microscopy; static electricity; surface property; transmission electron microscopy; waste water management; X ray photoemission spectroscopy; X ray powder diffraction; zeta potential | English | 2022 | 2022-04-01 | 10.1016/j.envres.2021.112532 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Nano Ag@bioactive microspheres from marine sponge Clathria frondifera: Fabrication, fortification, characterization, anticancer and antibacterial potential evaluation | Bioresources are attaining much importance in the discovery of drugs and delivering agents. In particular, marine sponges are of great interest due to their metabolites production for the survival in risky environment. The incorporation of silver nanoparticles with marine sponge derived metabolites was reported for the first time. In this work, a facile material has been generated of great efficacy in solving environmental and health issues, as a recipe of silver and marine sponge Clathria frondifera, named as Ag Fortified Sponge spheres (AFS). AFS spheres were successfully synthesized after method optimization, using the various extracts of marine sponge Clathria frondifera as effective reducing agent in Ag (I) to Ag (0) reduction. Bioactive material from marine sponge and AgNP from the reduction of AgNO3 solution stablishing one another and thus AFS spheres were attaining long lifetime along with enhanced antimicrobial activity. The characterization of synthesized AFS and other AgNPs (1-4) has done using FT-IR, PXRD, FESEM, TEM, and UV-vis data. The presence of functional groups such as, Ag-O, and Ag-C stretching bonds in the AFS compounds indicated that it is composed of silver oxides and organo-silver, respectively. The synthesized Ag NPs were found to be spherical like structure with an average size of similar to 20 nm. The cytotoxic response of AFS was assessed by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and morphological changes. AFS are exact spherical, micro sized and effective in inhibiting the growth of both gram positive and gram-negative bacteria. Anticancer studies were also carried out and ensued with excellent activity in the HELA cells with potential application in the medical industry. | Saravanakumar, Karunamoorthy; Abinaya, Manickavasagan; Mehnath, Sivaraj; Priya, Velmurugan Shanmuga; Jeyaraj, Murugaraj; Al-Rashed, Sarah; Muthuraj, Velluchamy | VHN Senthikumara Nadar Coll Autonomous, Dept Chem, Virudunagar 626001, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ Madras, Natl Ctr Nanosci & Nanotechnol, Guindy Campus, Chennai 600025, Tamil Nadu, India; Sri Kaliswari Coll Autonomous, Dept Chem, Sivakasi 626130, Tamil Nadu, India; King Saud Univ, Coll Sci, Dept Bot & Microbiol, PO 2455, Riyadh 11451, Saudi Arabia | Veluchamy, Muthuraj/AGO-8278-2022; Al-Rashed, Sarah/MFI-6935-2025; Sivaraj, Mehnath/JDD-4080-2023; Karunamoorthy, Saravanakumar/Q-2005-2016 | 57223020778; 59310087400; 57197754217; 57572775200; 55319143400; 36969750400; 57203214600 | muthuraj75@gmail.com; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 206 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 0.76 | 2025-06-25 | 9 | 10 | Marine sponge; Clathria frondifera; Silver fortification; Antimicrobial efficacy; Anticancer activity | ECO-FRIENDLY SYNTHESIS; SILVER NANOPARTICLES; GREEN SYNTHESIS; CANCER-TREATMENT; BIOSYNTHESIS; EXTRACT; DEGRADATION; ALGA | Anticancer activity; Antimicrobial efficacy; Clathria frondifera; Marine sponge; Silver fortification | Animals; Anti-Bacterial Agents; HeLa Cells; Humans; Metal Nanoparticles; Microbial Sensitivity Tests; Microspheres; Porifera; Silver; Spectroscopy, Fourier Transform Infrared; Clathria frondifera extract; distilled water; microsphere; natural product; reactive oxygen metabolite; reducing agent; silver nanoparticle; silver nitrate; unclassified drug; antiinfective agent; metal nanoparticle; microsphere; silver; antimicrobial activity; bacterium; cancer; cell; marine ecosystem; nanoparticle; silver; sponge; antibacterial activity; antineoplastic activity; aqueous solution; Article; Bacillus subtilis; bacterium isolation; biosynthesis; centrifugation; chemical structure; Clathria frondifera; cytotoxicity; drug delivery system; Escherichia coli; fluorescence microscopy; Fourier transform infrared spectroscopy; HeLa cell line; human; human cell; in vitro study; mass fragmentography; minimum inhibitory concentration; MTT assay; nonhuman; particle size; Pseudomonas aeruginosa; sponge (Porifera); Staphylococcus aureus; transmission electron microscopy; ultraviolet visible spectroscopy; X ray diffraction; animal; chemistry; infrared spectroscopy; metabolism; microbial sensitivity test | English | 2022 | 2022-04-15 | 10.1016/j.envres.2021.112282 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Noble metal nanoparticles (Mx = Ag, Au, Pd) decorated graphitic carbon nitride nanosheets for ultrafast catalytic reduction of anthropogenic pollutant, 4-nitrophenol | We report an effective facile immobilization of noble nanoparticles (Mx = Ag, Au and Pd) assembled on g-C3N4 (g-CN) prepared via a simple ultra-sonication strategy. The Mx assembled g-CN nanocomposites were applied for the effective conversion of 4-nitrophenol (4-NP). As prepared nanocomposites were characterized by techniques of XRD, SEM-EDS, TEM, XPS, and FT-IR analysis to gain crystallographic structural, and morphological insights. The Pd@g-C3N4 (Pd@g-CN) nanocomposite exhibited best catalytic performance (k(app) = 1.141 min -1) toward the conversion of 4-NP to 4-aminophenol (4-AP), almost 100% within 4 min using aqueous sodium borohydride (NaBH4). The higher catalytic efficiency of Pd@g-CN could be attributed to the surface electron density on the Pd and rapid electron transfer capacity. Interestingly, g-CN not only role as a stabilizer but also provided compatibility for noble metal deposition, which improves the chemical and morphological stability of noble metal nanoparticles. Different reaction parameters including concentrations of 4-NP, and catalyst amount were studied. These unique combinations make noble metal nanoparticles anchored g-CN nanosheets an ideal platform for catalysis applications and environmental remediation. | Saravanakumar, Karunamoorthy; Priya, Velmurugan Shanmuga; Balakumar, Vellaichamy; Prabavathi, Seenivasan Lakshmi; Muthuraj, Velluchamy | VHN Senthikumara Nadar Coll Autonomous, Dept Chem, Virudunagar 626001, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Sri Kaliswari Coll Autonomous, Dept Chem, Sivakasi 626130, Tamil Nadu, India; Kyushu Univ, Fac Engn, Dept Earth Resources Engn, Nishi Ku, 744 Motooka, Fukuoka 8190395, Japan | Veluchamy, Muthuraj/AGO-8278-2022; V, Balakumar/ABD-2114-2020; Karunamoorthy, Saravanakumar/Q-2005-2016 | 57223020778; 58760119700; 56703116400; 57200601983; 57203214600 | sravanan205@gmail.com; | ENVIRONMENTAL RESEARCH | ENVIRON RES | 0013-9351 | 1096-0953 | 212 | SCIE | ENVIRONMENTAL SCIENCES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 8.3 | 7.5 | 4.18 | 2025-06-25 | 53 | 55 | g-C3N4 nanosheets; Noble metal nanoparticles; 4-nitrophenol; Catalytic reduction | BIMETALLIC NANOPARTICLES; HEXAVALENT CHROMIUM; FACILE SYNTHESIS; GRAPHENE; PHOTODEGRADATION; NANOCOMPOSITES; PHOTOCATALYST; CONSTRUCTION; NITROPHENOLS; NANOHYBRIDS | 4-nitrophenol; Catalytic reduction; g-C<sub>3</sub>N<sub>4</sub> nanosheets; Noble metal nanoparticles | Catalysis; Environmental Pollutants; Graphite; Metal Nanoparticles; Nitrogen Compounds; Nitrophenols; Silver; Spectroscopy, Fourier Transform Infrared; 4 aminophenol; 4 nitrophenol; carbon nanoparticle; carbon nitride nanosheet; gold nanoparticle; graphite; nanocomposite; nanosheet; palladium nanoparticle; silver nanoparticle; sodium borohydride; unclassified drug; 4-nitrophenol; graphite; graphitic carbon nitride; metal nanoparticle; nitrogen derivative; nitrophenol; silver; catalysis; electron density; immobilization; metal; nanocomposite; nanoparticle; phenol; aqueous solution; Article; catalyst; catalytic efficiency; ecosystem restoration; electron transport; elemental analysis; energy dispersive X ray spectroscopy; field emission scanning electron microscopy; Fourier transform infrared spectroscopy; human impact (environment); immobilization; pollutant; reaction analysis; reduction (chemistry); scanning electron microscopy; surface property; transmission electron microscopy; ultrasound; ultraviolet visible spectroscopy; X ray diffraction; X ray photoemission spectroscopy; catalysis; chemistry; infrared spectroscopy | English | 2022 | 2022-09 | 10.1016/j.envres.2022.113185 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
