| ○ | ○ | Article | Real hypersurfaces with pseudo-Ricci-Bourguignon soliton in the complex two-plane Grassmannians | In this paper, we have investigated a pseudo-Ricci-Bourguignon soliton on real hypersurfaces in the complex two-plane Grassmannian G2(Cm+2). By using pseudo-anti commuting Ricci tensor, we give a complete classification of Hopf pseudo-Ricci-Bourguignon soliton real hypersurfaces in G2(Cm+2). Moreover, we have proved that there exists a non-trivial classification of gradient pseudo-Ricci-Bourguignon soliton (M, e, 17, S2, 0, & gamma; , g) on real hypersurfaces with isometric Reeb flow in the complex two-plane Grassmannian G2(Cm+2). In the class of contact hypersurface in G2(Cm+2), we prove that there does not exist a gradient pseudo-Ricci-Bourguignon soliton in G2(Cm+2). & COPY; 2023 Elsevier B.V.

| ○ | ○ | Article | Toward Single-Cell Multiple-Strategy Processing Shift Register Powered by Phase-Change Memory Materials | Modern innovations are built on the foundation of computers. Compared to von Neumann architectures having separate storage and processing units, in-memory operation utilizes the same primary structure for data storage and register operations, therefore promising to decrease the energy cost of computing in data centers significantly. While various studies centered on exploring novel device architectures, designing suitable material platforms is extremely challenging. Herein, all four material (M) states of a phase-change material (PCM) in data storage and register operations are utilized and a combined M state-based model framework for developing in-memory operation is demonstrated, along with nonvolatile, reprogrammable single-cell shift register operations. A previously unachieved multiple-level-per-volt different-initial-state multilevel set process with further computing in the M state-based platform is realized. The simplest case of a programmable shift register configuration is demonstrated with a serial-in-serial-out processing strategy, as well as more complex reprogrammable processing schemes using the M state-type platform, showing previously unreported nonvolatile shift register types with multiple processing approaches. This paves the way for development of next-generation low-power-electronic systems using two-terminal-based semiconductor materials. | Go, Shao-Xiang; Wang, Qiang; Huang, Kejie; Lee, Tae Hoon; Bajalovic, Natasa; Loke, Desmond K. | Singapore Univ Technol & Design, Dept Sci Math & Technol, Singapore 487372, Singapore; Zhejiang Univ, Coll Informat Sci & Elect Engn, Hangzhou 310027, Peoples R China; Univ Cambridge, Dept Engn, Trumpington St, Cambridge CB2 1PZ, England; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | Wang, Qiang/AAV-7131-2021; , 黄科杰/J-5919-2019; Lee, Tae/AAB-7490-2021 | 57226116052; 57219146363; 54581052800; 55731221000; 57207854156; 36096853500 | desmond_loke@sutd.edu.sg; | ADVANCED INTELLIGENT SYSTEMS | ADV INTELL SYST-GER | 2640-4567 | 5 | 3 | SCIE | AUTOMATION & CONTROL SYSTEMS;COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ROBOTICS | 2023 | 6.8 | 10.1 | 0.47 | 2025-06-25 | 0 | 4 | analog memory; edge computing; nonvolatile memory; phase-change materials; shift register | LOGIC OPERATIONS; CHALLENGES; ARRAY | analog memory; edge computing; nonvolatile memory; phase-change materials; shift register | Edge computing; Intelligent systems; Nonvolatile storage; Phase change materials; Phase change memory; Semiconductor materials; Shift registers; Analog memory; Data registers; Data storage; Edge computing; Memory operations; Non-volatile memory; Nonvolatile; Nonvolatile memory; Reprogrammable; Single cells; Memory architecture | English | 2023 | 2023-03 | 10.1002/aisy.202200353 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Tracking the sources of dissolved organic matter under bio- and photo-transformation conditions using fluorescence spectrum-based machine learning techniques | Dissolved organic matter (DOM) from various sources can lead to environmental issues such as eutrophication in agricultural watersheds. Effective source-tracking tools are needed to implement proper management practices. Fluorescence excitation-emission matrix (EEM) spectroscopy has been widely used to probe DOM composition. We explored optimal fluorescence EEM-based machine learning (ML) tools to quantify the proportions of different DOM sources in mixture samples under natural transformation conditions. Bulk DOM samples were prepared from soil and compost at various ratios and treated to simulate biogeochemical transformations. ML models based on all the EEM data outperformed those based on defined fluorescence indices. The trained support vector regression model (SVR) outperformed the conventional source tracking method of end-member mixing analysis (EMMA) with an R2 of 0.88 versus 0.83. Among the five suitable ML algorithms tested, SVR explained 90% and 85% of the variability in the proportions of soil and compost sources in the DOM mixture, with the mean squared errors of 0.004 and 0.007, respectively. The predicted capacity revealed a close relationship or causality between the specific mixing ratios of the bulk samples and the EEM spectra. The ML technique with EEM data was not constrained by the identification of all major sources, which is a required condition for the EMMA method. This study highlights the significant potential of EEM-based ML for tracing the source of DOM and establishes a basis for the future development of EEM data-driven models capable of tracking multiple DOM sources, even in the absence of all possible end-members.(c) 2023 The Author(s).

| ○ | ○ | Review | Abatement of odor emissions from wastewater treatment plants using biochar | Odor is a critical environmental problem that negatively affects people's quality of life. Wastewater treatment plants (WWTPs) often emit various odorous compounds, such as ammonia, sulfur dioxide, and organosulfur. Abatement of odor emissions from WWTPs using biochar may contribute to achieving carbon neutrality due to the carbon negative nature, CO2 sorption, and negative priming effects of biochar. Biochar has a high specific surface area and microporous structure with appropriate activation, which is suitable for sorption purposes. Various research directions have been proposed to determine the biochar removal efficiency for different odorants released from WWTPs. According to the literature survey, the pre- and post-treatments (e.g., thermal treatment, chemical treatment, and metal impregnation) of biochar could enhance the removal capacity for the odorants emitted from WWTPs at comparable conditions, compared to unmodified biochar. The feedstock and production condition (particularly, pyrolysis temperature) of a biochar and initial concentration of an odorant markedly affect the biochar's odorant removal capacity and efficiency. Moreover, different adsorption systems for the removal of odorants emitted from WWTPs follow different adsorption models. Further research is required to establish the practical use of biochar for the mitigation of odors released from WWTPs. | Lee, Jechan; Lee, Seonho; Lin, Kun-Yi Andrew; Jung, Sungyup; Kwon, Eilhann E. | Sungkyunkwan Univ, Dept Global Smart City, Suwon 16419, South Korea; Sungkyunkwan Univ, Sch Civil Architectural Engn & Landscape Architect, Suwon 16419, South Korea; Natl Chung Hsing Univ, Dept Environm Engn, Taichung, Taiwan; Natl Chung Hsing Univ, Innovat & Dev Ctr Sustainable Agr, Taichung, Taiwan; Natl Tsing Hua Univ, Inst Analyt & Environm Sci, Hsinchu, Taiwan; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea | Lee, Jechan/J-1229-2016; Kwon, Eilhann/AGY-3339-2022; Jung, Sungyup/ABE-1493-2021 | 57188712886; 57226690619; 44961317800; 55073290800; 9240622100 | ek2148@hanyang.ac.kr; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 336 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 0.47 | 2025-06-25 | 5 | 9 | Adsorbent; Adsorption; Biomass; Biowaste; Pyrolysis; Sustainable development goals (SDGs) | HIGH-PERFORMANCE REMOVAL; ACTIVATED CARBONS; METHYL MERCAPTAN; LOW-COST; ADSORPTION; PYROLYSIS; GAS; COLLECTION; COMPONENTS; SEPARATION | Adsorbent; Adsorption; Biomass; Biowaste; Pyrolysis; Sustainable development goals (SDGs) | Ammonia; Carbon; Efficiency; Odors; Sewage pumping plants; Sulfur dioxide; Sustainable development; Wastewater treatment; Water treatment plants; charcoal; Biochar; Biowastes; Condition; Environmental problems; Odour emissions; Quality of life; Removal capacity; Removal efficiencies; Sustainable development goal; Waste water treatment plants; adsorption; biochar; biomass; emission; odor; pyrolysis; Sustainable Development Goal; waste; wastewater treatment plant; adsorption; biomass; pyrolysis; Review; waste water treatment plant; Adsorption | English | 2023 | 2023-11-01 | 10.1016/j.envpol.2023.122426 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Algae-derived metal-free boron-doped biochar acts as a catalyst for the activation of peroxymonosulfate toward the degradation of diclofenac | In this study, plain seaweed biochar (SW) and boron-doped seaweed biochar (BSW) were prepared through a simple pyrolysis process using Undaria pinnatifida (algae biomass) and boric acid. The BSW catalyst was utilized to degrade organic pollutants in aqueous environments by activating peroxymonosulfate (PMS). Surface characterization of the BSW demonstrated successful doping of boron into the biochar materials. BSW600 exhibited greater catalytic activity than SW600, as evidenced by the former's maximum adsorption capacity of diclofenac (DCF) onto BSW600 (qmax = 30.01 mg g-1) and the activation of PMS. Complete degradation of DCF was achieved in 30 min using 100 mg L-1 BSW600, 0.5 mM PMS, and 6.5 initial solution pH as critical parameters. The pseudofirst-order kinetic model accurately described the DCF degradation kinetics. The scavenger experiment displayed that radical and non-radical reactive oxygen species (ROS) formed in the BSW600/PMS system. Furthermore, the generation of ROS in the BSW600/PMS system was confirmed by electron spin resonance spectroscopy (ESR). The percentage contribution of ROS was assessed to be 12.3, 45.0, and 42.7% for HO center dot, SO4 center dot-, and 1O2, respectively. Additionally, the electron transfer pathway was also confirmed by electrochemical analysis. Moreover, the influence of water matrics on the BSW600/PMS system was demonstrated. The co-existence of anions and humic acid (HA) did not affect the catalytic activity of the BSW600/PMS system. The recyclability of BSW600 was assessed by DCF removal (86.3%) after three cycles. Ecological structure-activity relationships software was used to assess by-product toxicity. This study demonstrates the efficacy of non-metallic heteroatom-doped biochar materials as eco-friendly catalysts in groundwater applications. | Annamalai, Sivasankar; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | ; Annamalai, Sivasankar/G-7823-2016 | 56388546200; 23019870800 | wshin@knu.ac.kr; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 331 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 2.55 | 2025-06-25 | 18 | 20 | Diclofenac; Seaweed; Boron -doped biochar; Peroxymonosulfate; Electron transfer pathway | CARBON NANOTUBES; OXIDATION; NITROGEN; TEMPERATURE; PHOSPHORUS; PATHWAYS; INSIGHTS; REMOVAL; SODIUM | Boron-doped biochar; Diclofenac; Electron transfer pathway; Peroxymonosulfate; Seaweed | Boron; Diclofenac; Metals; Peroxides; Reactive Oxygen Species; Water; Boric acid; Catalyst activity; Degradation; Electron spin resonance spectroscopy; Electron transitions; Free radical reactions; Groundwater; Magnetic moments; Organic pollutants; Seaweed; 2,4 dichlorophenol; anion; boric acid; boron; charcoal; ciprofloxacin; diclofenac; ground water; humic acid; oxygen; peroxymonosulfate; radical; reactive oxygen metabolite; sulfate; trimethoprim; unclassified drug; water; charcoal; metal; peroxide; peroxymonosulfate; Biochar; Boron-doped; Boron-doped biochar; Diclofenac; Electron transfer pathways; Metal free; Peroxymonosulfate; Reactive oxygen species; Simple++; ]+ catalyst; accuracy assessment; alga; biochar; biotechnology; boron; catalyst; drug; efficiency measurement; groundwater pollution; reaction kinetics; reactive oxygen species; seaweed; adsorption isotherm; adsorption kinetics; aqueous solution; Article; biomass; catalyst; controlled study; degradation; degradation kinetics; electrochemical analysis; electron spin resonance; electron transport; free radical scavenging assay; isotherm; pH; recycling; seaweed; structure activity relation; surface analysis; synthesis; toxicity testing; Undaria pinnatifida; water pollutant; Chemical activation | English | 2023 | 2023-08-15 | 10.1016/j.envpol.2023.121850 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Combined toxicity of 3,5,6-trichloro-2-pyridinol and 2-(bromomethyl) naphthalene in the early stages of zebrafish (Danio rerio) embryos: Abnormal heart development at lower concentrations via differential expression of heart forming-related genes | Combined toxicity can occur in the environment according to the combination of single substances, and the combination works additively or in a synergistic or antagonistic mode. In our study, 3,5,6-trichloro-2-pyridinol (TCP) and 2-(bromomethyl)naphthalene (2-BMN) were used to measure combined toxicity in zebrafish (Danio rerio) embryos. As the lethal concentration (LC) values were obtained through single toxicity, the lethal effects at all combinational concentrations were considered synergistic by the Independent Action model. At 96 hpf, the combined toxicity of TCP LC10 + 2-BMN LC10, the lowest combinational concentration, resulted in high mor-tality, strong inhibition of hatching, and various morphological changes in zebrafish embryos. Combined treatment resulted in the downregulation of cyp1a, leading to reduced detoxification of the treated chemicals in embryos. These combinations may enhance endocrine-disrupting properties via upregulation of vtg1 in embryos, and inflammatory responses and endoplasmic reticulum stress were found to upregulate il-beta, atf4, and atf6. These combinations might induce severe abnormal cardiac development in embryos via downregulation of myl7, cacna1c, edn1, and vmhc expression, and upregulation of the nppa gene. Therefore, the combined toxicity of these two chemicals was observed in zebrafish embryos, which proves that similar substances can exhibit stronger combined toxicity than single toxicity. | Jeon, Hwang-Ju; Cho, Yerin; Kim, Kyeongnam; Kim, Chaeeun; Lee, Sung-Eun | Louisiana State Univ Agr Ctr, Red River Res Stn, Bossier City, LA USA; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Qual & Safety Evaluat Agr Prod, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea | Kim, Kyeongnam/KSM-2719-2024; Jeon, Hwangju/JDW-9035-2023 | 56328792200; 58102413200; 57191364349; 57200245142; 55890041600 | selpest@knu.ac.kr; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 325 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 0.51 | 2025-06-25 | 3 | 4 | Combined toxicity; 3; 5; 6-Trichloro-2-pyridinol; 2-(bromomethyl)naphthalene; Zebrafish embryos; Abnormal cardiac formation | ENDOPLASMIC-RETICULUM-STRESS; HYDROCARBON RECEPTOR; MIXTURES; EXPOSURE | 2-(bromomethyl)naphthalene; 3,5,6-Trichloro-2-pyridinol; Abnormal cardiac formation; Combined toxicity; Zebrafish embryos | Animals; Embryo, Nonmammalian; Heart; Naphthalenes; Pyridones; Water Pollutants, Chemical; Zebrafish; Detoxification; Genes; Heart; Toxicity; Transmission control protocol; 2 (bromomethyl) naphthalene; 3,5,6 trichloro 2 pyridinol; endocrine disruptor; naphthalene; pyridinol; unclassified drug; 3,5,6-trichloro-2-pyridinol; dipyrone; naphthalene; naphthalene derivative; 2-(bromomethyl)naphthalene; 3,5,6-trichloro-2-pyridinol; Abnormal cardiac formation; Combined toxicity; Down-regulation; Heart development; Lethal concentration; Up-regulation; Zebrafish danio rerio; Zebrafish embryos; chemical pollutant; concentration (composition); cyprinid; embryo; experimental study; gene expression; physiological response; toxicity; animal tissue; Article; atf4 gene; atf6 gene; cacna1c gene; controlled study; cyp1a gene; detoxification; down regulation; edn1 gene; embryo; endoplasmic reticulum; gene; gene expression; hatching; heart development; il beta gene; inflammation; lethal concentration; morphology; mortality; myl7 gene; nonhuman; nppa gene; toxicity testing; upregulation; vmhc gene; vtg1 gene; zebra fish; animal; heart; nonmammalian embryo; pharmacology; physiology; water pollutant; Naphthalene | English | 2023 | 2023-05-15 | 10.1016/j.envpol.2023.121450 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Developmental toxicity of fipronil and its two metabolites towards zebrafish (Danio rerio) embryo | Fipronil (FIL) use is currently regulated in several countries due to its specific toxicity to bees. This study investigated the possible developmental toxicities as well as the acute toxicities of FIL, fipronil sulfide (FIL-SI), and fipronil sulfone (FIL-SO) to zebrafish (Danio rerio) embryos. At concentrations up to 5000 & mu;g L-1, FIL-and FIL-SI-treated embryos exhibited significant mortality at 96 h postfertilization. Body length was significantly shortened with increasing concentrations in FIL-and FIL-SI-treated embryos. However, FIL-SO-treated embryos exhibited low mortality with high hatching rates. Body length was also significantly shortened in FIL-SO-treated embryos. Regarding the number of intersegmental vessels (ISVs), all chemical-treated embryos showed high ISV numbers with increasing concentrations of each chemical. FIL and FIL-SI induced abnormal heart formation with heart dysfunction in embryos, whereas FIL-SO did not induce any difference in heart development compared with the control. Abnormal heart formation may be related to the upregulation of nppa responsible for the expression of natriuretic peptides in embryos. Embryonic acetylcholinesterase activity was decreased gradually according to the increase in FIL and FIL-SI concentrations, whereas FIL-SO did not cause any change in enzyme activity. Il-1 & beta; responsible for the occurrence of injury or infection was highly upregulated in FIL-SI- and FIL-SO-treated embryos. Therefore, reduction to FIL-SI may be associated with FIL toxicity, whereas oxidation to FIL-SO may be a detoxification route in the environment. | Kim, Chaeeun; Lee, Sung-Eun | Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea | 57200245142; 55890041600 | selpest@knu.ac.kr; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 333 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 1.02 | 2025-06-25 | 7 | 9 | Fipronil; Fipronil sulfide; Fipronil sulfone; Cardiac abnormality; Nppa gene | EXPOSURE; INSECTICIDES; WATER | Cardiac abnormality; Fipronil; Fipronil sulfide; Fipronil sulfone; Nppa gene | Acetylcholinesterase; Animals; Embryo, Nonmammalian; Water Pollutants, Chemical; Zebrafish; Detoxification; Enzyme activity; Heart; Metabolites; Sulfur compounds; fipronil; fipronil sulfide; fipronil sulfone; insecticide; unclassified drug; acetylcholinesterase; fipronil; Acute toxicity; Cardiac abnormality; Developmental toxicity; Fipronil; Fipronil sulphide; Fipronil sulphone; Nppa gene; Zebrafish danio rerio; concentration (composition); cyprinid; embryo; fipronil; metabolite; toxicity; animal embryo; animal experiment; Article; congenital heart malformation; controlled study; developmental toxicity; embryo; female; gene; gene expression; male; metabolite; nonhuman; Nppa gene; pollutant; zebra fish; animal; metabolism; nonmammalian embryo; water pollutant; zebra fish; Toxicity | English | 2023 | 2023-09-15 | 10.1016/j.envpol.2023.122119 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Drinking water treatment and associated toxic byproducts: Concurrence and urgence | Reclaimed water is highly required for environmental sustainability and to meet sustainable development goals (SDGs). Chemical processes are frequently associated with highly hazardous and toxic by-products, like nitro-samines, trihalomethanes, haloaldehydes, haloketones, and haloacetic acids. In this context, we aim to sum-marize the formation of various commonly produced disinfection by-products (DBPs) during wastewater treatment and their treatment approaches. Owing to DBPs formation, we discussed permissible limits, concen-trations in various water systems reported globally, and their consequences on humans. While most reviews focus on DBPs detection methods, this review discusses factors affecting DBPs formation and critically reviews various remediation approaches, such as adsorption, reverse osmosis, nano/micro-filtration, UV treatment, ozonation, and advanced oxidation process. However, research in the detection of hazardous DBPs and their removal is quite at an early and initial stage, and therefore, numerous advancements are required prior to scale-up at commercial level. DBPs abatement in wastewater treatment approach should be considered. This review provides the baseline for optimizing DBPs formation and advancements in the remediation process, efficiently reducing their production and providing safe, clean drinking water. Future studies should focus on a more efficient and rigorous understanding of DBPs properties and degradation of hazardous pollutants using low-cost techniques in wastewater treatment. | Kumar, Manish; Shekhar, Shashank; Kumar, Rakesh; Kumar, Pawan; Govarthanan, Muthusamy; Chaminda, Tushara | Univ Petr & Energy Studies, Sustainabil Cluster, Dehra Dun 248007, Uttarakhand, India; Tecnol Monterrey, Escuela Ingn & Ciencias, Campus Monterey, Monterrey 64849, Nuevo Leon, Mexico; Nalanda Univ, Sch Ecol & Environm Studies, Rajgir 803116, Bihar, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak-Ro, Daegu 41566, South Korea; Saveetha Dent Coll & Hosp, Saveetha Inst Med & Tech Sci, Dept Biomat, Chennai 600077, India; Univ Ruhuna, Fac Engn, Dept Civil & Environm Engn, Galle, Sri Lanka | Shekhar, Shashank/JSL-0954-2023; Kumar, Rakesh/ABA-5632-2020; Govarthanan, Muthusamy/C-1491-2014; Muthusamy, Govarthanan/C-1491-2014; kumar, manish/KIE-1953-2024 | 55456390100; 57188965475; 57408065700; 57203136143; 54881927600; 23104846300 | manish.env@gmail.com; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 320 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 1.78 | 2025-06-25 | 30 | 35 | Chlorination; Ozonation; UV radiations; N-nitrosodimethylamine (NDMA); Trihalomethanes (THMs); Drinking water | N-NITROSODIMETHYLAMINE NDMA; GRANULAR ACTIVATED CARBON; NATURAL ORGANIC-MATTER; MAMMALIAN-CELL CYTOTOXICITY; HALOACETIC ACID REMOVAL; SWIMMING POOL WATER; NITROSAMINE PRECURSORS; HALOGENATED DBPS; REVERSE-OSMOSIS; BREAKPOINT CHLORINATION | Chlorination; Drinking water; N-nitrosodimethylamine (NDMA); Ozonation; Trihalomethanes (THMs); UV radiations | Disinfectants; Disinfection; Drinking Water; Halogenation; Humans; Nitrosamines; Trihalomethanes; Water Pollutants, Chemical; Water Purification; Chlorination; Hazards; Ozone; Ozone water treatment; Potable water; Sustainable development; Ultraviolet radiation; Wastewater treatment; dimethylnitrosamine; drinking water; haloaldehyde; haloketone; nitrosamine; oxidizing agent; polyvinylchloride; trihalomethane; water; disinfectant agent; drinking water; nitrosamine; Disinfection by product formations; Disinfection by-product; Disinfection byproducts; Drinking water treatment; N-nitrosodimethylamine; Re-claimed water; Toxic byproducts; Trihalomethane; Trihalomethanes; chlorination; drinking water; ozonation; toxicity; ultraviolet radiation; water treatment; adsorption; anticoagulation; aquatic environment; attention; biodegradation; bioremediation; carcinogenicity; chlorination; degradation; denitrification; disinfection; electrochemistry; human; irradiation; mass spectrometry; microfiltration; microorganism; nanofiltration; oxidation; ozonation; pH; photolysis; phytoremediation; pollutant; prevalence; reverse osmosis; Review; sustainable development goal; ultraviolet phototherapy; waste water management; wastewater; water contamination; water pollution; water supply; water treatment; chemistry; halogenation; procedures; water management; water pollutant; Ozonization | English | 2023 | 2023-03-01 | 10.1016/j.envpol.2023.121009 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficacy of endophytic SB10 and glycine betaine duo in alleviating phytotoxic impact of combined heat and salinity in Glycine max L. via regulation of redox homeostasis and physiological and molecular responses | Adverse environmental stresses occurring simultaneously exhibit a lethal effect on crop productivity at the global level. Here, we investigated the individual and synergistic effects of endophytic T. virens SB10 and glycine betaine (GB) on the physiological and biochemical responses of Glycine max L. to alleviate the devastating effects of combined heat and salinity (HS) stress. Screening against HS stress tolerance showed that SB10 has significant tolerance against heat stress and produces hormones such as gibberellins and indole-3-acetic acid upon GB amendment of the growth medium under HS stress. Moreover, the current findings illustrated that the synergistic application of SB10 and GB was effective in alleviating the negative effects of HS stress on plant growth and physiology. The findings revealed that SB10 + GB led to a reduction in proline accumulation and Na+ uptake. It also maintained a high K+/Na + ratio by regulating GmHKT1 and GmSOS1 expression and enhanced macronutrient uptake (N, Ca, K) in plants. In turn, plants exhibited a higher growth rate and gaseous exchange attributes coupled with the upregulation of APX, SOD, POD, and GSH antioxidant activities and transcript accumulation of GmSOD1 and GmAPX1 to overcome HS-induced oxidative damage. Furthermore, SB10 + GB downregulated DREB2, DREB1B, and GmNCED3 expression and resulted in the reduced accumulation of endogenous ABA while enhancing endogenous SA accumulation via upregulation of PAL genes. In addition, enhanced accumulation of bioactive gibberellins (GA1, GA3, GA4, and GA7) was detected under HS stress in the SB10 + GB treatment group. Moreover, SB10 + GB also significantly regulated GmHsp90A2 and GmHsfA2 expression in tolerance against HS stress. The combination of SB10 and GB was shown to be an effective and alternative approach for growing G. max at high temperature coupled with saline conditions for sustainable agriculture. | Bilal, Saqib; Shahzad, Raheem; Asaf, Sajjad; Imran, Muhammad; Al-Harrasi, Ahmed; Lee, In -Jung | Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa 616, Oman; Univ Haripur, Dept Hort, Haripur 22620, Khyber Pakhtunk, Pakistan; Kyungpook Natl Univ, Sch Appl Biosci, Daegu, South Korea | Shahzad, Raheem/JDM-3580-2023; Imran, Muhammad/AFL-6590-2022; Lee, In-Jung/GLS-0432-2022; Asaf, Sajjad/ABA-3647-2021; Ul-Hamid, Anwar/B-7297-2015 | 57031617400; 56454250900; 56595059900; 58282433800; 6506093146; 16425830900 | saqib@unizwa.edu.om;raheemshehzad@ymail.com;sajjadasaf@unizwa.edu.om;aharrasi@unizwa.edu.om; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 316 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 1.91 | 2025-06-25 | 13 | 15 | High temperature; Salinity; Endophytic fungi; Soybean; Hormones; Abscisic acid; Salicylic acid; Gibberellic acid | STRESS TOLERANCE; FOLIAR APPLICATION; PLANT-GROWTH; PHYTOREMEDIATION; BIOSYNTHESIS; DROUGHT; SILICON | Abscisic acid; Endophytic fungi; Gibberellic acid; High temperature; Hormones; Salicylic acid; Salinity; Soybean | Betaine; Gibberellins; Homeostasis; Oxidation-Reduction; Salinity; Soybeans; Amino acids; Betaines; Endocrinology; Environmental regulations; Fungi; Physiological models; Physiology; Salicylic acid; antioxidant; ascorbate peroxidase; betaine; calcium; gibberellic acid; gibberellin; glycine; indoleacetic acid; phytohormone; proline; reactive oxygen metabolite; salicylic acid; sodium; sodium ion; betaine; gibberellin; Abscisic acid; Combined heat; Endophytic fungus; Gibberellic acid; Glycine betaine; Heat stress; Highest temperature; Salinity; Salinity stress; Soybean; abscisic acid; biochemistry; endophyte; fungus; high temperature; homeostasis; hormone; physiological response; phytotoxicity; salicylic acid; salinity; soybean; Article; endophytic fungus; heat; nonhuman; oxidation reduction reaction; phytotoxicity; plant growth; protein phosphorylation; salt stress; synergistic effect; homeostasis; metabolism; oxidation reduction reaction; salinity; soybean; Hormones | English | 2023 | 2023-01-01 | 10.1016/j.envpol.2022.120658 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enantioselective effect of trifloxystrobin in early-stage zebrafish (Danio rerio) embryos: Cardiac abnormalities impacted by E E-trifloxystrobin enantiomer | Trifloxystrobin (TFS) is one of the extensively used strobilurin fungicides, which is composed of four enantiomers and its active form is E,E-TFS. In this study, we assess the acute toxicity of four enantiomers, E,E-, E,Z-, Z,E-, and Z,Z-TFS in zebrafish (Danio rerio) embryos. Among the four enantiomers, only E,E-TFS was found to be acutely toxic, with an estimated LC50 value of 0.68 mg/L. Treatment with E,E-TFS resulted in various phenotypic changes in the embryos, including pericardial and yolk-sac edema, spine curvature, and blood pooling. And it shortened the whole body length in the treated embryos by increasing the total intersegmental vessel numbers using a Tg(fli1a:EGFP) zebrafish line. Further study using Tg(cmlc2:EGFP) zebrafish line revealed that E,E-TFS treatment was associated with cardiac malformations, a failure of heart function, and a lowered heartbeat rate at the concentration of 0.25 mg/L. Also, the differential gene expression analysis identified significant down-regulation of vmhc and cacna1c genes encoding ventricular myosin heavy chain and calcium voltage-gated channel subunit alpha 1C, which are crucial for heart development. These results suggest the need for regular monitoring of E,E-TFS enantiomers after field application and further research into their potential chronic effects on environmental organisms. | Kim, Yurim; Jeon, Hwang-Ju; Kim, Kyeongnam; Kim, Chaeeun; Moon, Joon-Kwan; Hwang, Kyu-Won; Lee, Sung-Eun | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Louisiana State Univ, Red River Res Stn, Agr Ctr, Bossier City, LA USA; Kyungpook Natl Univ, Inst Qual & Safety Evaluat Agr Prod, Daegu 41566, South Korea; Hankyong Natl Univ, Dept Plant Resources & landscape Architecture, Anseong 17579, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea | Jeon, Hwangju/JDW-9035-2023; Kim, Kyeongnam/KSM-2719-2024 | 57397370800; 56328792200; 57191364349; 57200245142; 8536720000; 56763314600; 55890041600 | selpest@knu.ac.kr; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 327 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 1.15 | 2025-06-25 | 9 | 10 | E-trifloxystrobin; Enantioselective toxicity; Abnormal development; Cardiac function failure; Calcium voltage-gated channel | ENVIRONMENTAL FATE; STROBILURINS; EXPRESSION; APOPTOSIS; STRESS | Abnormal development; Calcium voltage-gated channel; Cardiac function failure; E,E-trifloxystrobin; Enantioselective toxicity | Animals; Embryo, Nonmammalian; Stereoisomerism; Strobilurins; Water Pollutants, Chemical; Zebrafish; Enantiomers; Enantioselectivity; Failure (mechanical); Gene expression; Heart; Toxicity; trifloxystrobin; voltage gated calcium channel; strobilurin; trifloxystrobin; Abnormal development; Calcium voltage-gated channel; Cardiac function failure; Cardiac functions; E,E-trifloxystrobin; Enantioselective; Enantioselective toxicity; Gated channels; Trifloxystrobin; Zebrafish danio rerio; calcium; concentration (composition); cyprinid; fungicide; gene expression; toxicity; acute toxicity; Article; cacna1c gene; congenital heart malformation; controlled study; embryo; embryotoxicity; enantiomer; enantioselectivity; gene; gene control; gene expression; heart failure; heart rate; LC50; nonhuman; pollutant; vmhc gene; zebra fish; animal; genetics; nonmammalian embryo; stereoisomerism; water pollutant; Calcium | English | 2023 | 2023-06-15 | 10.1016/j.envpol.2023.121537 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Engineered ball-milled colloidal activated carbon material for advanced oxidation process of ibuprofen: Influencing factors and insights into the mechanism | This study explores a simple and efficient, physically modified ball-milled activated carbon (AC(BM)) preparation from granular activated carbon (GAC), which can be demonstrated for groundwater application. The colloidal stability of the AC(BM) plays a vital role in the activation of peroxymonosulfate (PMS) and the degradation of pollutants. Adsorption kinetics and isotherm studies explain that the AC(BM) has more active sites and maximum adsorption capacity (q(max) = 509 mg g(-1)) on the surface of the materials than GAC. The 92% of ibuprofen degradation was achieved at 240 min along with 0.1 g L-1 of AC(BM), 5 mM of PMS, and 6.3 of initial solution pH. A chemical scavenger and electron spin resonance spectra also confirmed the formation of reactive oxygen species such as radicals (O-2(center dot-), HO center dot, SO4 center dot-) and non-radical (O-1(2)) in the AC(BM)/PMS system. Three major degradation pathways, hydroxylation, demethylation, and decarboxylation involved in ibuprofen degradation. Nearly 13 degradation by-products were detected during the AC(BM)/PMS oxidation of ibuprofen. The toxicity analysis of oxidation by-products of ibuprofen was also discussed by computational simulation employing the ecological structure-activity relationships software. The AC(BM)/PMS system was successfully applied to the natural groundwater system for ibuprofen degradation. Hence, the AC(BM)/PMS system is an excellent catalyst for real groundwater applications. | Lee, Sang Hoon; Annamalai, Sivasankar; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | Annamalai, Sivasankar/G-7823-2016 | 56812964000; 56388546200; 23019870800 | wshin@knu.ac.kr; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 322 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 2.8 | 2025-06-25 | 22 | 23 | Ball-milled activated carbon; Degradation mechanism; Ibuprofen; Peroxymonosulfate; Singlet oxygen | ORGANIC CONTAMINANTS; DEGRADATION; PERSULFATE; REMOVAL; ADSORPTION; CHEMISORPTION; REMEDIATION; CATALYST; ACID | Ball-milled activated carbon; Degradation mechanism; Ibuprofen; Peroxymonosulfate; Singlet oxygen | Charcoal; Ibuprofen; Oxidation-Reduction; Peroxides; Carboxylation; Computer software; Degradation; Electron spin resonance spectroscopy; Groundwater; Magnetic moments; Oxidation; Oxygen; Sols; activated carbon; ground water; holmium; ibuprofen; oxygen; peroxymonosulfate; radical; reactive oxygen metabolite; sulfate; unclassified drug; charcoal; peroxide; Advanced Oxidation Processes; Ball-milled; Ball-milled activated carbon; Carbon material; Degradation mechanism; Granular activated carbons; Ibuprofen; Peroxymonosulfate; Simple++; Singlet oxygen; activated carbon; adsorption; computer simulation; decarboxylation; degradation; drug; electron spin resonance; groundwater; oxidation; reactive oxygen species; toxicity test; adsorption kinetics; Article; biodegradation; bioengineering; catalyst; colloid; computer model; concentration (parameter); controlled study; decarboxylation; demethylation; drug degradation; electrochemistry; electron spin resonance; environmental impact; hydroxylation; isotherm; molecular stability; oxidation; particle size; pH; physical chemistry; structure activity relation; chemistry; oxidation reduction reaction; Activated carbon | English | 2023 | 2023-04-01 | 10.1016/j.envpol.2023.121023 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Kidney tissue regeneration using bioactive scaffolds incorporated with differentiating extracellular vesicles and intermediate mesoderm cells | Background To overcome the limitations of current alternative therapies for chronic kidney disease (CKD), tissue engineering-mediated regeneration strategies have demonstrated the possibilities for complete kidney tissue regeneration. Given the challenges associated with the reproducibility of renal basal cells, the incorporation of intermediate mesoderm (IM) cells and bioactive materials to control bioactivities of cells with supported scaffolds should be considered as a viable approach to enable the regeneration of the complex kidney structure via renal differentiation. Methods We developed PMEZ scaffolds by combining crucial bioactive components, such as ricinoleic acid-grafted Mg(OH)2 (M), extracellular matrix (E), and alpha lipoic acid-conjugated ZnO (Z) integrated into biodegradable porous PLGA (P) platform. Additionally, we utilized differentiating extracellular vesicles (dEV) isolated during intermediate mesoderm differentiation into kidney progenitor cells, and IM cells were serially incorporated to facilitate kidney tissue regeneration through their differentiation into kidney progenitor cells in the 3/4 nephrectomy mouse model. Results The use of differentiating extracellular vesicles facilitated IM differentiation into kidney progenitor cells without additional differentiation factors. This led to improvements in various regeneration-related bioactivities including tubule and podocyte regeneration, anti-fibrosis, angiogenesis, and anti-inflammation. Finally, implanting PMEZ/dEV/IM scaffolds in mouse injury model resulted in the restoration of kidney function. Conclusions Our study has demonstrated that utilizing biodegradable PLGA-based scaffolds, which include multipotent cells capable of differentiating into various kidney progenitor cells along with supporting components, can facilitate kidney tissue regeneration in the mouse model that simulates CKD through 3/4 nephrectomy. | Cha, Seung-Gyu; Rhim, Won-Kyu; Kim, Jun Yong; Lee, Eun Hye; Lee, Seung Yeon; Park, Jeong Min; Lee, Jeoung Eun; Yoon, Hyeji; Park, Chun Gwon; Kim, Bum Soo; Kwon, Tae Gyun; Lee, Youngmi; Lee, Dong Ryul; Han, Dong Keun | CHA Univ, Dept Biomed Sci, 335 Pangyo Ro, Seongnam Si 13488, Gyeonggi Do, South Korea; Sungkyunkwan Univ SKKU, SKKU Inst Convergence, Dept Biomed Engn, 2066 Seobu Ro, Suwon 16419, Gyeonggi Do, South Korea; Sungkyunkwan Univ SKKU, SKKU Inst Convergence, Intelligent Precis Healthcare Convergence, 2066 Seobu Ro, Suwon 16419, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Joint Inst Regenerat Med, Daegu 41571, South Korea; CHA Univ, CHA Adv Res Inst, Bundang Med Ctr, Seongnam Si 13488, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Med, Dept Urol, Daegu 41944, South Korea; Ewha Womans Univ, Dept Chem & Nanosci, Seoul, South Korea | ; Lee, Jeong/JFA-4725-2023; Kim, Jun Yong/MBG-4766-2025 | 57312341800; 36825029800; 57214807525; 57189661699; 58741526300; 58247139200; 59643960000; 58740489800; 40361321700; 57202817150; 15073765400; 35237907700; 36158065400; 7403219478 | dkhan@cha.ac.kr; | BIOMATERIALS RESEARCH | BIOMATER RES | 1226-4601 | 2055-7124 | 27 | SCIE | ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS | 2023 | 8.1 | 10.2 | 0.68 | 2025-06-25 | 4 | 5 | Kidney tissue regeneration; PMEZ scaffold; Intermediate mesoderm (IM); Differentiating extracellular vesicle (dEV); Kidney differentiation | MESENCHYMAL STEM-CELLS; MAGNESIUM-HYDROXIDE; PROGENITOR CELLS; NITRIC-OXIDE; PARTICLES; POLYDEOXYRIBONUCLEOTIDE | Differentiating extracellular vesicle (dEV); Intermediate mesoderm (IM); Kidney differentiation; Kidney tissue regeneration; PMEZ scaffold | magnesium hydroxide; polyglactin; ricinoleic acid; thioctic acid; zinc oxide; zinc oxide nanoparticle; angiogenesis; animal cell; animal experiment; animal model; animal tissue; antifibrotic activity; antiinflammatory activity; Article; biodegradability; biological activity; cell differentiation; controlled study; exosome; extracellular matrix; human; human cell; immune response; in vitro study; in vivo study; kidney cell; kidney function; kidney injury; kidney tissue; kidney tubule; mesodermal cell; mouse; nephrectomy; nephron; nonhuman; nude mouse; pH; physical chemistry; pluripotent stem cell; podocyte; porosity; stem cell; three dimensional cell culture; tissue regeneration; two dimensional cell culture | English | 2023 | 2023-12-05 | 10.1186/s40824-023-00471-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Melatonin alleviates arsenic (As) toxicity in rice plants via modulating antioxidant defense system and secondary metabolites and reducing oxidative stress | The Arsenic (As) load on the environment has increased immensely due to large-scale industrial and agricultural uses of As in several synthetic products, such as fertilizers, herbicides, and pesticides. Melatonin is a plant hormone that has a key role in abiotic stress inhibition, but the mechanism of resilience to As stress remains unexplored in rice plants. In this study, we determined how As affects rice plant and how melatonin facilitate As stress tolerance in rice. Here we investigated that, exogenous melatonin reduced As stress by inducing anthocyanin biosynthesis. Melatonin induced the expression of anthocyanin biosynthesis genes such as PAL, CHS, CHI, F3H, DFR, and ANS, which resulted in 1659% and 389% increases in cyanidin and delphinidin, respectively. Similarly, melatonin application significantly induced SA and ABA accumulation in response to As stress in rice plant. Application of melatonin also significantly reduced expression of PT-2 and PT-8 (transporter genes) and reduced uptake of As and its translocation to other compartments. Melatonin and As analysis revealed that melatonin application significantly reduced As contents in the melatonin-supplemented plants, suggesting that As uptake is largely dependent on either the melatonin basal level or anthocyanin in rice plants. In this study, we investigated new symptoms on leaves, which can severely damage leaves and impair photosynthesis. However, anthocyanin as a chelating agent, detoxifies As in vacuole and reduces oxidative stress induced by As. | Jan, Rahmatullah; Asif, Saleem; Asaf, Sajjad; Lubna; Du, Xiao-Xuan; Park, Jae-Ryoung; Nari, Kim; Bhatta, Dibya; Lee, In-jung; Kim, Kyung-Min | Kyungpook Natl Univ, Grad Sch, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Coastal Agr Res Inst, Daegu 41566, South Korea; Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa, Oman; Natl Acad Agr Sci Rural Dev Adm, Biosafty Div, Jeonju 54874, South Korea; Natl Inst Crop Sci, Rural Dev Adm, Crop Breeding Div, Wonju 55365, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu, South Korea | Kim, Kyung-Min Kim/C-7007-2014; Asaf, Sajjad/ABA-3647-2021; Jan, Rahmatullah/AIC-3439-2022; Du, Xiaoxuan/AGZ-8638-2022; Lee, In-Jung/GLS-0432-2022 | 57201981969; 57396413700; 56595059900; 57200621537; 57209098077; 57211205505; 58030902800; 57450591300; 16425830900; 34868260300 | kkm@knu.ac.kr; | ENVIRONMENTAL POLLUTION | ENVIRON POLLUT | 0269-7491 | 1873-6424 | 318 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 7.6 | 10.2 | 6.62 | 2025-06-25 | 51 | 52 | Arsenic; Melatonin; Transporter genes; Oxidative stress; Anthocyanin; Chelating agent | NITROGEN CONSERVATION; HEAVY-METALS; CADMIUM; BIOCHAR; ACCUMULATION; TOLERANCE; SEQUESTRATION; RESISTANCE; MECHANISM; TRANSPORT | Anthocyanin; Arsenic; Chelating agent; Melatonin; Oxidative stress; Transporter genes | Anthocyanins; Antioxidants; Arsenic; Melatonin; Oryza; Oxidative Stress; Alkaloids; Anthocyanins; Arsenic; Biosynthesis; Chelation; Chemical industry; Genes; Hormones; Oxidative stress; Plants (botany); acetic acid; anthocyanin; antioxidant; arsenic; calcium; cyanidin chloride; cyclopentane; delphinidin; fertilizer; flavonoid; heavy metal; herbicide; melatonin; naringenin; pesticide; polyphenol; reactive oxygen metabolite; anthocyanin; antioxidant; melatonin; Anthocyanin biosynthesis; Antioxidant defense system; Arsenic toxicity; Chelating agent; Industrial use; Large-scales; Melatonin; Rice plants; Secondary metabolites; Transporter genes; antioxidant; arsenic; chelating agent; metabolite; oxidative stress; rice; toxicity; abiotic stress; Article; bioaccumulation; biosynthesis; cell vacuole; cytosol; detoxification; DNA extraction; enzyme activity; enzyme linked immunosorbent assay; exogenous variable; gas chromatography; gene expression; genotype; high performance liquid chromatography; inductively coupled plasma mass spectrometry; lipid peroxidation; mass fragmentography; metabolite; nonhuman; oxidative stress; particle size; photosynthesis; physiological stress; phytoremediation; plant growth; plant height; real time polymerase chain reaction; rice; RNA isolation; seedling; transgenic plant; genetics; metabolism; Oryza; oxidative stress; Metabolites | English | 2023 | 2023-02-01 | 10.1016/j.envpol.2022.120868 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Pr3+-doped CeF3 crystals: Analysis of optical traits and fluorescence from Pr3+: 1D2 level for visible and near-infrared lasers | In this work, four Pr3+-doped CeF3 crystals with 0.2, 0.4, 0.6, and 0.8 at.% Pr3+ion doping levels nominally in the melt have been successfully grown, and their absorption and emission spectra, including fluorescence decay times were analyzed. Especially, yellow and near-infrared (NIR) emissions originating from Pr3+: 1D2 level were explored in detail. In comparison, 0.2 at.% Pr3+-doped sample showed better spectral parameters in all studied crystals. In such a crystal, at 443 nm wavelength, the derived absorption cross-section (sigma abs) is 0.88 x 10-20 cm2 with full width at half maximum (FWHM) - 10 nm in pi polarization direction, whereas sigma abs is 1.32 x 10-20 cm2 with FWHM - 6.7 nm in sigma polarization direction at the same wavelength. Likewise, the calculated emission cross-section (sigma em) for 594 nm wavelength is 0.69 x 10-20 cm2 in pi direction and 0.46 x 10-20 cm2 in sigma direction. Also, acquired sigma em at 790, 755, 1014, and 1432 nm wavelengths is 6.15 x 10-21 cm2, 7.33 x 10-21 cm2, 7.66 x 10-21 cm2, and 6.56 x 10-21 cm2 individually. Here evaluated fluorescence decay time of 1D2 level is - 200.6 mu s. Obtained higher sigma abs, larger sigma em, and higher luminescence decay rates of 0.2 at.% Pr: CeF3 crystal specify its potential as a gain medium for orange and NIR lasers. | Zheng, Longxing; Wang, Yan; Yang, Jiaxue; Zhu, Zhaojie; You, Zhenyu; Li, Jianfu; Tu, Chaoyang; Lakshminarayana, G. | Chinese Acad Sci, Fujian Inst Res Struct Matter, Key Lab Optoelect Mat Chem & Phys, Fuzhou 350002, Fujian, Peoples R China; Fuzhou Univ, Coll Chem, Fuzhou 350116, Peoples R China; Mindu Innovat Lab, Fujian Sci & Technol Innovat Lab Optoelect Informa, Fuzhou 350108, Fujian, Peoples R China; Kyungpook Natl Univ, Intelligent Construct Automat Ctr, 80 Daehakn Ro, Daegu 41566, South Korea | zhenyu, You/HTQ-5042-2023 | 57487931500; 55992327100; 57552376500; 7404803891; 7102207842; 8643618700; 57194637883; 55543060400 | tcy@fjirsm.ac.cn; | SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY | SPECTROCHIM ACTA A | 1386-1425 | 1873-3557 | 290 | SCIE | SPECTROSCOPY | 2023 | 4.3 | 10.2 | 0.29 | 2025-06-25 | 2 | 2 | Judd-Ofelt analysis; Luminescence traits; Orange laser; Near-infrared laser | JUDD-OFELT ANALYSIS; SINGLE-CRYSTALS; SPECTROSCOPY; DIODE; OPERATION; GROWTH; EMISSION; RED; INTENSITIES; ABSORPTION | <sup>1</sup>D<sub>2</sub> level; Judd-Ofelt analysis; Luminescence traits; Near-infrared laser; Orange laser; Pr<sup>3+</sup>: CeF<sub>3</sub> crystal | Cerium compounds; Citrus fruits; Crystals; Doping (additives); Emission spectroscopy; Fluorescence; Fluorine compounds; Full width at half maximum; Polarization; 1D2 level; Fluorescence decay time; Full widths at half maximums; Judd-ofelt analysis; Luminescence trait; Near-infrared lasers; Optical-; Orange laser; Polarization direction; Pr3+: CeF3 crystal; Infrared devices | English | 2023 | 2023-04-05 | 10.1016/j.saa.2022.122252 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
