Several studies analyze biomass-derived biochar techniques and environmental applications, but comprehensive assessments of biochar limitations, uncertainty, and future research directions still need to be improved. This critical review aims to present a comprehensive analysis of biochar's efficacy in environmental applications, including soil, water, and air, by sequentially addressing its preparation, application, and associated challenges. The review begins by delving into the diverse methods of biochar production, highlighting their influence on physical and chemical properties. This review explores the diverse applications of biochar in remediating contaminated soil, water, and air while emphasizing its sustainability and eco-friendly characteristics. The focus is on incorporating biochar as a remediation technique for pollutant removal, sequestration, and soil improvement. The review highlights the promising results obtained from laboratory-scale experiments, field trials, and case studies, showcasing the effectiveness of biochar in mitigating contaminants and restoring ecosystems. The environmental benefits and challenges of biochar production, characterization, and application techniques are critically discussed. The potential synergistic effects of combining biochar with other remediation methods are also explored to enhance its efficacy. A rigorous analysis of the benefits and drawbacks of biochar for diverse environmental applications in terms of technical, environmental, economic, and social issues is required to support the commercialization of biochar for large-scale uses. Finally, future research directions and recommendations are presented to facilitate the development and implementation of biochar-based, sustainable green remediation strategies. | Al Masud, Md Abdullah; Shin, Won Sik; Sarker, Aniruddha; Septian, Ardie; Das, Kallol; Deepo, Deen Mohammad; Iqbal, Mohammad Asif; Islam, Abu Reza Md Towfiqul; Malafaia, Guilherme | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Rural Dev Adm, Natl Inst Agr Sci, Residual Chem Assessment Div, Jeonju Si 55365, Jeollabuk Do, South Korea; Natl Res & Innovat Agcy, Badan Riset dan Inovasi Nasl, Res Ctr Environm & Clean Technol, BRIN, Serpong 15314, Indonesia; Kyungpook Natl Univ, Coll Agr & Life Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Univ Technol Sydney, Fac Sci, Sydney, Australia; Begum Rokeya Univ, Dept Disaster Management, Rangpur 5400, Bangladesh; Daffodil Int Univ, Dept Dev Studies, Dhaka 1216, Bangladesh; Goiano Fed Inst, Lab Toxicol Appl Environm, Urutai Campus, Urutai, Brazil; Goiano Fed Inst, Postgrad Program Conservat Cerrado Nat Resourc, Urutai, Go, Brazil; Univ Fed Uberlandia, Postgad Program Ecol Conservat & Biodivers, Uberlandia, MG, Brazil; Univ Fed Goias, Postgrad Program Biotechnol & Biodivers, Goiania, Go, Brazil | Septian, Ardie/HGB-8696-2022; Das, Kallol/AAR-6707-2020; Islam, Abu Reza Md.

| ○ | ○ | Review | Advanced technologies for the determination of quantitative structure-activity relationships and degradation efficiency of micropollutants and their removal in water - A review | The growing concentrations of micropollutants in aquatic ecosystems are a global water quality issue. Understanding micropollutants varied chemical composition and potency is essential to solving this complex issue. Micropollutants management requires identifying contaminants to reduce, optimal reduction targets, and the best wastewater recycling locations. Management requires appropriate technological measures. Pharmaceuticals, antibiotics, hormones, and other micropollutants can enter the aquatic environment from point and diffuse sources, with wastewater treatment plants (WWTPs) distributing them in urban areas. Micropollutants like pharmaceuticals and hormones may not be removed by conventional WWTPs. Micropollutants affect the EU, especially in densely populated areas where surface water is consumed. This review examines several technological options that can be integrated into existing treatment methods to address this issue. In this work, oxidation, activated carbon, and their combinations as potential solutions, considering their efficacy and cost were evaluated. This study illuminates micropollutants origin and physico-chemical properties, which affect distribution, persistence, and environmental impacts. Understanding these factors helps us develop targeted micropollutant mitigation strategies to protect water quality. This review can inform policy and decision-making to reduce micropollutant impacts on aquatic ecosystems and human health. | Ratchnashree, S.

| ○ | ○ | Article | Application of poly (vinyl alcohol)-cryogels to immobilizing nitrifiers: Enhanced tolerance to shear stress-induced destruction and viability control | The hardness of poly (vinyl alcohol)-cryogels (PVA-CGs) was improved under three parameter conditions: 7.5 %- 12.5 % PVA, 1-5 freezing-thawing cycles (FTCs), and the addition of 0 %-10 % glycerol as a cryoprotectant. This study investigated the effects of shear stress-induced destruction (SSID) on mechanical strength by inducing rapid ero-sion with a high frictional force. Tolerance to SSID (Tol-SSID) exhibited different sensitivities and trends depending on the above three fabrication parameters. The measured Tol-SSID exhibited consistent and inconsistent trends with ten -sile strength and swelling, respectively. Tol-SSID evaluation provides new insights into the practically meaningful me-chanical strength of PVA-CGs against strong friction, which simulates extreme shear stress in a bioreactor. A PVA-CG with a PVA concentration of 10 % and in two FTCs resulted in Tol-SSID and tensile strength of 88.3 % and 0.59 kPa, respectively. Here, 5 % glycerol was added to maintain the bacterial respiration activity of immobilized nitrifiers of 0.097 mg-O2/g-VSS center dot min and survival of 88.6 %. The continuous mode of nitrification using the optimized PVA-CG for 10 days resulted in an ammonia removal rate of 0.2173 kg-N/m3 center dot d, which is an improvement over cases without glycerol addition: 0.1426 and 0.1472 kg-N/m3 center dot d for PVA-CGs in two and three FTCs, respectively. | Song, Minsu; Park, Jihye; Jeon, Junbeom; Ha, Yun-Geun; Cho, Young-Rae; Koo, Hyung-Jun; Kim, Woong; Bae, Hyokwan | Pusan Natl Univ, Dept Civil & Environm Engn, 63 Busandeahak ro, Busan 46241, South Korea; Pusan Natl Univ, Inst Environm & Energy, 63 Busandeahak ro, Busan 46241, South Korea; Pusan Natl Univ, Sch Mat Sci & Engn, 63 Busandeahak ro, Busan 46241, South Korea; Seoul Natl Univ Sci & Technol, Dept Chem & Biomol Engn, 232 Gongneung ro, Seoul 01811, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Ulsan Natl Inst Sci & Technol UNIST, Dept Urban & Environm Engn, 50 UNIST gil,Eonyang eup, Ulsan 44919, South Korea; Ulsan Natl Inst Sci & Technol, Grad Sch Carbon Neutral, Ulsan 44919, South Korea | ; Koo, Hyung/D-7145-2011 | 57668121100; 57667462700; 57668121000; 57221397992; 7404469735; 20434028500; 55581636400; 58299012900 | hyokwan.bae@unist.ac.kr; | SCIENCE OF THE TOTAL ENVIRONMENT | SCI TOTAL ENVIRON | 0048-9697 | 1879-1026 | 855 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.2 | 8.5 | 0.45 | 2025-06-25 | 5 | 5 | Poly (vinyl alcohol) cryogel; Tolerance to shear stress-induced destruction; Viability; Cryoprotectant; Ammonia removal rate | POLYVINYL-ALCOHOL PVA; AMMONIUM WASTE-WATER; MECHANICAL-PROPERTIES; CROSS-LINKING; NITROGEN REMOVAL; ANAMMOX PROCESS; HIGH-STRENGTH; GEL BEADS; HYDROGELS; NITRIFICATION | Ammonia removal rate; Cryoprotectant; Poly (vinyl alcohol) cryogel; Tolerance to shear stress-induced destruction; Viability | Bioreactors; Cryogels; Glycerol; Polyvinyl Alcohol; Stress, Mechanical; Ammonia; Fits and tolerances; Friction; Glycerol; Nitrification; Polyvinyl alcohols; Shear flow; Tensile strength; cryogel; polyvinyl alcohol; glycerol; polyvinyl alcohol; Ammonia removal; Ammonia removal rate; Cryogels; Cryoprotectants; Poly (vinyl alcohol) (PVA); Poly (vinyl alcohol) cryogel; Poly(vinyl alcohol); Poly(vinyl alcohol) (PVA); Removal rate; Stress-induced; Tolerance to shear stress-induced destruction; Viability; alcohol; erosion; pollutant removal; shear stress; survival; swelling; tensile strength; tolerance; viability; ammonia oxidizing bacterium; Article; biodegradability; biomass; breathing; cell destruction; cell viability; chemical reaction kinetics; controlled study; crystallization; destruction; elasticity; field emission scanning electron microscopy; fluorescence analysis; freeze thawing; glycolysis; hydrophilicity; immobilized cell; live cell imaging; nanofabrication; nitrification; nonhuman; oxygen consumption; polymerization; room temperature; shear stress; surface property; suspended particulate matter; swelling; tensile strength; waste water management; wound healing; bioreactor; cryogel; mechanical stress; Shear stress | English | 2023 | 2023-01-10 | 10.1016/j.scitotenv.2022.158835 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Applications of agricultural residue biochars to removal of toxic gases emitted from chemical plants: A review | Crop residues are representative agricultural waste materials, massively generated in the world. However, a large fraction of them is currently being wasted, though they have a high potential to be used as a value-added carbonrich material. Also, the applications of carbon-rich materials from agricultural waste to industries can have economic benefit because waste-derived carbon materials are considered inexpensive waste materials. In this review, valorization methods for crop residues as carbon-rich materials (i.e., biochars) and their applications to industrial toxic gas removals are discussed. Applications of crop residue biochars to toxic gas removal can have significant environmental benefits and economic feasibility. As such, this review discussed the technical advantages of the use of crop residue biochars as adsorbents for hazardous gaseous pollutants and greenhouse gases (GHGs) stemmed from combustion of fossil fuels and the different refinery processes. Also, the practical benefits from the activation methods in line with the biochar properties were comprehensively discussed. The relationships between the physico-chemical properties of biochars and the removal mechanisms of gaseous pollutants (H2S, SO2, Hg0, and CO2) on biochars were also highlighted in this review study. Porosity controls using physical and chemical activations along with the addition of specific functional groups and metals on biochars have significantly contributed to the enhancement of flue gas adsorption. The adsorption capacity of biochar for each toxic chemical was in the range of 46-76 mg g-1 for H2S, 40-182 mg g-1 for SO2, 80-952 mu g g-1 for Hg0, and 82-308 mg g-1 CO2, respectively. This helps to find suitable activation methods for adsorption of the target pollutants. In the last part, the benefits from the use of biochars and the research directions were prospectively provided to make crop residue biochars more practical materials in adsorp-tion of pollutant gases. | Cho, Seong-Heon; Lee, Sangyoon; Kim, Youkwan; Song, Hocheol; Lee, Jechan; Tsang, Yiu Fai; Chen, Wei-Hsin; Park, Young -Kwon; Lee, Dong-Jun; Jung, Sungyup; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Sungkyunkwan Univ, Dept Global Smart City, Suwon 16419, South Korea; Sungkyunkwan Univ, Sch Civil Architectural Engn & Landscape Architect, Suwon 16419, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Hong Kong 999077, Peoples R China; Natl Cheng Kung Univ, Dept Aeronaut & Astronaut, Tainan 701, Taiwan; Tunghai Univ, Res Ctr Smart Sustainable Circular Econ, Taichung 407, Taiwan; Natl Chin Yi Univ Technol, Dept Mech Engn, Taichung 411, Taiwan; Univ Seoul, Sch Environm Engn, Seoul 02504, South Korea; Natl Inst Anim Sci NIAS, Dept Anim Environm, Wonju 55365, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Tsang, Yiu/AAJ-2524-2020; Chen, Wei-Hsin/S-2033-2018; Lee, Sang/ABC-8385-2020; Kwon, Eilhann/AGY-3339-2022; Song, Hocheol/ABD-7214-2021; Lee, Jechan/J-1229-2016 | 56583023200; 57214885455; 57204070895; 56562122800; 57188712886; 22954605700; 57200873137; 16029749100; 57191538179; 55073290800; 9240622100 | sjung001@knu.ac.kr;ek2148@hanyang.ac.kr; | SCIENCE OF THE TOTAL ENVIRONMENT | SCI TOTAL ENVIRON | 0048-9697 | 1879-1026 | 868 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.2 | 8.5 | 4.01 | 2025-06-25 | 39 | 47 | Agricultural waste; Circular bioeconomy; Waste-to-resource; Harmful chemical mitigation; Activated carbon; Biochar | CAO/ACTIVATED CARBON SORBENTS; ELEMENTAL MERCURY ADSORPTION; OXYGEN FUNCTIONAL-GROUPS; MUNICIPAL SOLID-WASTE; ACTIVATED CARBON; ANAEROBIC-DIGESTION; CO2 CAPTURE; SULFUR-DIOXIDE; H2S ADSORPTION; POROUS CARBON | Activated carbon; Agricultural waste; Biochar; Circular bioeconomy; Harmful chemical mitigation; Waste-to-resource | Adsorption; Carbon; Carbon Dioxide; Charcoal; Environmental Pollutants; Gases; Mercury; Activated carbon; Air pollution; Carbon dioxide; Chemical activation; Crops; Economic and social effects; Fog; Fossil fuels; Gas adsorption; Greenhouse gases; Waste incineration; charcoal; fossil fuel; toxic gas; carbon; carbon dioxide; charcoal; mercury; Biochar; Carbon-rich materials; Chemical mitigations; Circular bioeconomy; Crop residue; Gas removal; Harmful chemical mitigation; Harmful chemicals; Toxic gas; Waste-to-resource; activated carbon; adsorption; alternative agriculture; biochar; cost-benefit analysis; environmental economics; feasibility study; industrial emission; mitigation; waste management; adsorption; agricultural waste; agriculture; air pollution; anaerobic digestion; Article; biomass; composting; corrosion; greenhouse gas; municipal solid waste; nonhuman; physical chemistry; plant growth; plant residue; soil quality; valorization; chemistry; gas; pollutant; Agricultural wastes | English | 2023 | 2023-04-10 | 10.1016/j.scitotenv.2023.161655 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Clinical utility of quantitative immunoassays and surrogate virus neutralization tests for predicting neutralizing activity against the SARS-CoV-2 Omicron BA.1 and BA.5 variants | Developing new antibody assays for emerging SARS-CoV-2 variants is challenging. SARS-CoV-2 surrogate virus neutralization tests (sVNT) targeting Omicron BA.1 and BA.5 have been devised, but their performance needs to be validated in comparison with quantitative immunoassays. First, using 1749 PRNT-positive sera, we noticed that log-transformed optical density (OD) ratio of wild-type (WT) sVNT exhibited better titer-correlation with plaque reduction neutralization test (PRNT) than % inhibition value. Second, we tried 798 dilutional titration tests with 103 sera, but nonlinear correlation between OD ratio and antibody concentration limited titration of sVNT. Third, the titer-correlations of two sVNT kits for BA.1 and two quantitative immunoassays for WT were evaluated with BA.1 and BA.5 PRNT. All tested kits exhibited a linear correlation with PRNT titers, but the sVNT kits exhibited high false-negative rates (cPass-BA.1 kit, 45.4% for BA.1 and 44.2% for BA.5; STANDARD F-BA.1 kit, 1.9% for BA.1 and 2.2% for BA.5), while quantitative immunoassays showed 100% sensitivity. Linear mixed-effects model suggested superior titer-correlation with PRNT for quantitative immunoassays compared to sVNT kits. Taken together, the use of quantitative immunoassays for WT, rather than rapid development of new kits, would be practical for predicting neutralizing activities against emerging new variants. | Lee, Beomki; Ko, Jae-Hoon; Kim, Yong Chan; Baek, Jin Yang; Park, Yoon Soo; Song, Kyoung-Ho; Kim, Eu Suk; Lee, Kyoung Hwa; Song, Young Goo; Ahn, Jin Young; Choi, Jun Yong; Choi, Won Suk; Bae, Seongman; Kim, Sung-Han; Jeong, Hye Won; Lee, Young Jae; Kim, Hye-Jin; Choi, Ju-Yeon; Kim, Byoungguk; Kim, Shin-Woo; Kwon, Ki Tae; Peck, Kyong Ran; Kang, Eun-Suk | Sungkyunkwan Univ, Samsung Med Ctr, Dept Lab Med & Genet, Sch Med, 81 Irwon Ro, Seoul 06531, South Korea; Korea Adv Inst Sci & Technol KAIST, Grad Sch Med Sci & Engn, Daejeon, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Sch Med, Div Infect Dis,Dept Med, 81 Irwon Ro, Seoul 06351, South Korea; Yonsei Univ, Coll Med, Yongin Severance Hosp, Div Infect Dis,Dept Internal Med, Yongin, South Korea; Asia Pacific Fdn Infect Dis APFID, Seoul, South Korea; Seoul Natl Univ, Coll Med, Seoul Natl Univ Bundang Hosp, Dept Internal Med, Seongnam, South Korea; Yonsei Univ, Coll Med, Gangnam Severance Hosp, Div Infect Dis,Dept Internal Med, Seoul, South Korea; Yonsei Univ, Coll Med, Severance Hosp, Dept Internal Med, Seoul, South Korea; Korea Univ, Coll Med, Ansan Hosp, Div Infect Dis,Dept Internal Med, Ansan, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Infect Dis, Seoul, South Korea; Chungbuk Natl Univ, Coll Med, Dept Internal Med, Cheongju, South Korea; Korea Natl Inst Hlth, Natl Inst Infect Dis, Ctr Vaccine Res, Div Vaccine Clin Res, Cheongju, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Div Infect Dis,Dept Internal Med, 807 Hoguk Ro, Daegu 41404, South Korea | Lee, Kyoung-Hwa/AAJ-5213-2021; Baek, Jin Yang/JXO-3331-2024; Choi, Won Suk/V-2730-2017; Kim, So-Youn/H-4368-2016; Park, Yoon/C-6472-2015; Jeong, Hye/AET-1982-2022; Choi, Won/V-2730-2017; Choi, Jah/AAA-4835-2022; Kim, Hanjin/KYP-2633-2024; Peck, Kyong Ran/AGV-5205-2022 | 57224582420; 55804188300; 36486497700; 8926034300; 7405373036; 23398486700; 22938086900; 56955948100; 55675198500; 57225850337; 57791298700; 56718971800; 57189690904; 55133790400; 13103042700; 57218948191; 59412639300; 57203732512; 57792610600; 8710731500; 9733850500; 55664295200; 20234715300 | ksw2kms@knu.ac.kr;ktkwon@knu.ac.kr;krpeck@skku.edu;eskang@skku.edu; | JOURNAL OF MEDICAL VIROLOGY | J MED VIROL | 0146-6615 | 1096-9071 | 95 | 12 | SCIE | VIROLOGY | 2023 | 6.8 | 8.5 | 0.57 | 2025-06-25 | 3 | 3 | COVID-19; immunoassay; neutralizing antibodies; SARS-CoV-2 variants | INTERNATIONAL STANDARD | COVID-19; immunoassay; neutralizing antibodies; SARS-CoV-2 variants | Antibodies, Neutralizing; Antibodies, Viral; COVID-19; Humans; Immunoassay; Neutralization Tests; SARS-CoV-2; SARS-CoV-2 variants; neutralizing antibody; virus antibody; antibody blood level; Article; cohort analysis; controlled study; false negative result; human; immunoassay; major clinical study; nonhuman; optical density; plaque reduction neutralization test; prediction; SARS-CoV-2 (lineage BA.1); SARS-CoV-2 (lineage BA.5); sensitivity analysis; Severe acute respiratory syndrome coronavirus 2; surrogate virus neutralization test; titrimetry; virus neutralization; wild type; coronavirus disease 2019; genetics; immunoassay; neutralization test; Severe acute respiratory syndrome coronavirus 2 | English | 2023 | 2023-12 | 10.1002/jmv.29329 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Comparative analysis of organic chemical compositions in airborne particulate matter from Ulaanbaatar, Beijing, and Seoul using UPLC-FT-ICR-MS and artificial neural network | This paper presents comparative study on the composition and sources of PM2.5 in Ulaanbaatar, Beijing, and Seoul. Ultrahigh performance liquid chromatography (UPLC) combined with ultrahigh resolution mass spectrometry (UHR-MS) were employed to analyze 85 samples collected in winter. The obtained 340 spectra were interpreted with artificial neural network (ANN). PM2.5 mass concentrations in Ulaanbaatar were significantly higher than those in Beijing and Seoul. ANN based interpretation of UPLC UHR-MS data showed that aliphatic/ lipid derived organo-sulfur compounds, polycyclic aromatic and organo-oxygen compounds were characteristic to Ulaanbaatar. Whereas, aliphatic/lipid-derived organo-oxygen compounds were major components in Beijing and Seoul. Aromatic organo-nitrogen compounds were the main contributors to differentiating the spectra obtained from Beijing from the other cities. Based on two-dimensional gas chromatography/high resolution mass spectrometric (GCxGC/HRMS) data, it was determined that the concentrations of the polycyclic aromatic hydrocarbon (PAH) and polycyclic aromatic sulfur heterocycle (PASH) containing sulfur were highest in Ulaanbaatar, followed by Beijing and Seoul. Coal/biomass combustion was identified as the primary source of contamination in Ulaanbaatar, while petroleum combustion was the main contributor to PM2.5 in Beijing and Seoul. The conclusion that diesel-powered heavy-duty trucks and buses are the main contributors to NOx emissions in Beijing is consistent with previous reports. This study provides a more comprehensive understanding of the composition and sources of PM2.5 in the three cities, with a focus on the differences in their atmospheric pollution profiles based on the UPLC UHR-MS and ANN analysis. It is notable that this study is the first to utilize this method on a large-scale sample set, providing a more detailed and molecular-level understanding of the compositional differences among PM2.5.

| ○ | ○ | Article | Deep neural network prediction for effective thermal conductivity and spreading thermal resistance for flat heat pipe | Purpose This study aims to introduce a deep neural network (DNN) to estimate the effective thermal conductivity of the flat heat pipe with spreading thermal resistance. Design/methodology/approach A total of 2,160 computational fluid dynamics simulation cases over up to 2,000 W/mK are conducted to regress big data and predict a wider range of effective thermal conductivity up to 10,000 W/mK. The deep neural networking is trained with reinforcement learning from 10-12 steps minimizing errors in each step. Another 8,640 CFD cases are used to validate. Findings Experimental, simulational and theoretical approaches are used to validate the DNN estimation for the same independent variables. The results from the two approaches show a good agreement with each other. In addition, the DNN method required less time when compared to the CFD. Originality/value The DNN method opens a new way to secure data while predicting in a wide range without experiments or simulations. If these technologies can be applied to thermal and materials engineering, they will be the key to solve thermal obstacles that many longing to overcome. | Kim, Myeongjin; Moon, Joo Hyun | Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu, South Korea; Sejong Univ, Dept Mech & Aerosp Engn, Seoul, South Korea | Moon, Joo/AAN-3395-2021 | 55541419000; 56388836900 | jhmoon9@sejong.ac.kr; | INTERNATIONAL JOURNAL OF NUMERICAL METHODS FOR HEAT & FLUID FLOW | INT J NUMER METHOD H | 0961-5539 | 1758-6585 | 33 | 2 | SCIE | MATHEMATICS, INTERDISCIPLINARY APPLICATIONS;MECHANICS;THERMODYNAMICS | 2023 | 4 | 8.5 | 1.95 | 2025-06-25 | 17 | 17 | Computational fluid dynamics; Effective thermal conductivity; Flat heat pipe; Neural network; Thermal system design | VAPOR CHAMBER | Computational fluid dynamics; Effective thermal conductivity; Flat heat pipe; Neural network; Thermal system design | Computational fluid dynamics; Forecasting; Heat pipes; Heat resistance; Reinforcement learning; Thermal conductivity; Thermal Engineering; Computational fluid dynamics simulations; Design/methodology/approach; Effective thermal conductivity; Flat heat pipe; Neural network method; Neural network predictions; Neural-networks; Spreading thermal resistance; Thermal spreading; Thermal system design; Deep neural networks | English | 2023 | 2023-01-05 | 10.1108/hff-10-2021-0685 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Double-layer adhesives for preventing anastomotic leakage and reducing post-surgical adhesion | Preventing anastomotic leakage (AL) and postoperative adhesions after gastrointestinal surgery is crucial for ensuring a favorable surgical prognosis. However, AL prevention using tissue adhesives can unintentionally lead to undesirable adhesion formation, while anti-adhesive agents may interfere with wound healing and contribute to AL. In this study, we have developed a double-layer patch, consisting of an adhesive layer on one side, utilizing gallic acid-conjugated chitosan (CHI-G), and an anti-adhesive layer on the opposite side, employing crosslinked hyaluronic acid (cHA). These CHI-G/cHA double-layer adhesives significantly prevented AL by forming physical barriers of CHI-G and reduced post-surgical adhesion at the anastomosis sites by the anti-adhesive layers of cHA. The bursting pressure (161.1 +/- 21.6 mmHg) of double-layer adhesives-applied rat intestine at postoperative day 21 was far higher than those of the control (129.4 +/- 5.7 mmHg) and the commercial anti-adhesives-applied group (120.8 +/- 5.2 mmHg). In addition, adhesion score of double-layer adhesives-applied rat intestine was 3.6 +/- 0.3 at postoperative day 21, which was similar to that of the commercial anti-adhesives-applied group (3.6 +/- 0.3) and lower than that of the control group (4.9 +/- 0.5). These findings indicate that the double-layer patch (CHI-G/cHA) has the potential to effectively prevent both postoperative adhesions and anastomotic leakage, offering a promising solution for gastrointestinal surgery. | Kang, Sung Il; Shin, Hyun Ho; Hyun, Da Han; Yoon, Ghilsuk; Park, Jun Seok; Ryu, Ji Hyun | Yeungnam Univ, Coll Med, Dept Surg, Daegu 42415, South Korea; Wonkwang Univ, Dept Chem Engn, Iksan 54538, Jeonbuk, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu 41566, South Korea; Kyungpook Natl Univ, Colorectal Canc Ctr, Chilgok Hosp, Sch Med, Daegu 41404, South Korea; Wonkwang Univ, Dept Carbon Convergence Engn, Iksan 54538, Jeonbuk, South Korea; Wonkwang Univ, Smart Convergence Mat Anal Ctr, Iksan 54538, Jeonbuk, South Korea | Park, Joonhong/AAZ-9885-2020 | 57191976856; 57890302900; 58089142700; 57204691355; 35226761100; 57208277508 | parkjs0802@knu.ac.kr;jhryu4816@wku.ac.kr; | MATERIALS TODAY BIO | MATER TODAY BIO | 2590-0064 | 23 | SCIE | ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS | 2023 | 8.7 | 8.5 | 1 | 2025-06-25 | 10 | 9 | Intestinal anastomosis; Colorectal cancer; Gallic acid-conjugated chitosan; Crosslinked hyaluronic acid; Double layer | SMALL-BOWEL OBSTRUCTION; INTESTINAL ANASTOMOSES; COLONIC ANASTOMOSIS; RISK-FACTORS; CYANOACRYLATE; STRENGTH; CHITOSAN; SUTURE | Colorectal cancer; Crosslinked hyaluronic acid; Double layer; Gallic acid-conjugated chitosan; Intestinal anastomosis | Adhesion; Adhesives; Diseases; Hyaluronic acid; Organic acids; Rats; Surgery; Anti-adhesive; Colorectal cancer; Crosslinked; Crosslinked hyaluronic acid; Double layers; Gallic acid-conjugated chitosan; Gallic acids; Intestinal anastomosis; Postoperative adhesions; Surgical adhesions; Chitosan | English | 2023 | 2023-12 | 10.1016/j.mtbio.2023.100806 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Effective hydrolysis for waste plant biomass impacts sustainable fuel and reduced air pollution generation: A comprehensive review | Among various natural biowastes availability in the environment, agricultural residues showed great impacts. It is due to huge availability and cheap carbon source, creating big challenges for their utility and systematic reduction. Objec-tive of this review is to address the waste biomass availability and huge quantities issues and also put effort to minimize this nutrient load via biotransforming into value-added products. Different wastes (organic/inorganic) generation with their negative issues are due to numbers of developmental and social activities, reported. Currently, various efforts are found for these wastes minimization via generation of different types of value-added products (biogas, bioH2, alcoholic fuel, organic acids and others products) and these wastes in municipal cities are also reported with production of ad-vanced biofuels as promising outcomes. For hydrolysis of complex organic resources including lignocellulosic bio-masses, physicochemical, structural or compositional changes are needed that aid in conversion into sugar and organic compounds such as biofuels. So, efficient and effective pretreatment processes selection (physical, biological, chemical or combined one) is critical to achieve these hydrolysis goals and resultant cellulose or hemicellulose compo-nents can be accessible by biological catalysis. These can achieve final hydrolysis and fermentative or monomer sugars. And later, synthesis of fuels or value-added products during microbial fermentation or biotransformation processes can be achieved. This review discusses pretreatment techniques for improved hydrolysis for fermentative sugar with emphasis on reduced quantities of toxic compounds (furfural compound) in hydrolyzed biomasses. Minimum deteri-oration fuel economy also reported with production of different bioproducts including biofuels. Additionally, impacts of toxic products and gasses emission are also discussed with their minimization. | Srivastava, Rajesh K.; Nedungadi, Sruthy Vineed; Akhtar, Nasim; Sarangi, Prakash Kumar; Subudhi, Sanjukta; Shadangi, Krushna Prasad; Govarthanan, Muthusamy | Gandhi Inst Technol & Management GITAM, GITAM Sch Technol, Dept Biotechnol, Visakhapatnam 530045, India; Cent Agr Univ, Coll Agr, Imphal, Manipur, India; Energy & Resources Inst, Adv Biofuels program, Darbari Seth Block,Habitat Pl,Lodhi Rd, New Delhi 110003, India; Veer Surendra Sai Univ Technol, Dept Chem Engn, Sambalpur, Odisha, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Saveetha Dent Coll & Hosp, Saveetha Inst Med & Tech Sci, Dept Biomat, Chennai 600077, India | Srivastava, Rajesh/O-5322-2017; Shadangi, Krushna/AAW-2138-2021; Sarangi, Dr Prakash Kumar/AAA-4809-2022; Muthusamy, Govarthanan/C-1491-2014; Govarthanan, Muthusamy/C-1491-2014; Subudhi, Dr Sanjukta/ABD-3871-2021; Akhtar, Nasim/AAP-4527-2021 | 57198400808; 57541063000; 16306237400; 58924075200; 22939790400; 37064984500; 54881927600 | rajeshksrivastava73@yahoo.co.in;sarangi77@yahoo.co.in; | SCIENCE OF THE TOTAL ENVIRONMENT | SCI TOTAL ENVIRON | 0048-9697 | 1879-1026 | 859 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.2 | 8.5 | 2.49 | 2025-06-25 | 25 | 28 | Efficient hydrolysis; Biofuels; Microbial pathways; Fermentation; Lignocellulosic biomass; Pollution control | HOT-WATER PRETREATMENT; LIGNOCELLULOSIC BIOMASS; EMISSION CHARACTERISTICS; ENZYMATIC-HYDROLYSIS; BUTANOL PRODUCTION; CHEMICAL-COMPOSITION; BIOFUEL PRODUCTION; CORN STOVER; PERFORMANCE; COMBUSTION | Biofuels; Efficient hydrolysis; Fermentation; Lignocellulosic biomass; Microbial pathways; Pollution control | Air Pollution; Biomass; Cellulose; Degradation; Fermentation; Pollution Control; Air Pollution; Biofuels; Biomass; Carbohydrates; Fermentation; Hydrolysis; Lignin; Sugars; Agricultural wastes; Air pollution; Biofuels; Biomass; Cellulose; Deterioration; Fermentation; Pollution control; biodiesel; bioethanol; biofuel; biogas; carbohydrate; carboxylic acid; cellulase; cellulose; coconut oil; diesel fuel; flavonoid; fructose; furfural; gasoline; glibenclamide; hemicellulose; hydrogen peroxide; lignin; lignocellulose; manganese peroxidase; monomer; organic compound; palm oil; phenol; phytochemical; prebiotic agent; proline; sugar; sulfur dioxide; tetrahydrocannabinol; toxic substance; vaccine; xylan; % reductions; Biowastes; Carbon source; Efficient hydrolysis; Lignocellulosic biomass; Microbial pathway; Plant biomass; Sustainable fuels; Value added products; Waste biomass; atmospheric pollution; biofuel; biomass; fermentation; hydrolysis; pollution control; sustainability; waste facility; Actinobacteria; Agrobacterium tumefaciens; air pollution; alcoholism; anaerobic digestion; Article; autolysis; bacterial growth; bioenergy; biomass; bioremediation; biosynthesis; biotransformation; catalysis; Cellulomonas; composting; corrosion; delignification; deterioration; drought stress; economic aspect; energy conversion; enzyme activity; Escherichia coli; fermentation; gamma radiation; high performance liquid chromatography; human; hydrolysis; medicinal plant; microbial consortium; municipal solid waste; nonhuman; nutrient; particle size; particulate matter; pH; Phanerochaete; physical chemistry; pollution control; pyrolysis; recycling; Ruminococcus; saccharification; soil pollution; solid waste management; Streptomyces; temperature; Trichoderma; waste minimization; biomass; hydrolysis; metabolism; Hydrolysis | English | 2023 | 2023-02-10 | 10.1016/j.scitotenv.2022.160260 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhancing groundwater management using aggregated-data analysis and segmented robust regression: A case study on spatiotemporal changes in water quality | Groundwater quality management, crucial for ensuring sustainable water resources and public health, is the scope of this study. Our objective is to demonstrate the significance of secondary data analysis for the spatiotemporal characterization of groundwater quality. To this end, we develop and employ a robust trend analysis method, in tandem with a spatiotemporal data aggregation method, to accurately identify shifts in groundwater quality over time, even in the face of inflection points or breakpoints. The methods and results reveal diverse trends and characteristics in water quality over space and time across the entire dataset from selected regions in South Korea, emphasizing the importance of analyzing aggregated data beyond individual business locations. The conclusions indicate that this study contributes to the development of more reliable and effective groundwater quality management strategies by addressing gaps in traditional monitoring methods and the challenges of limited monitoring resources and uneven data quality. Future research directions include the application of the developed methods to other regions and data sources, opening avenues for further advances in groundwater quality management. | Piao, Jize; Nam, Seong Woo; Kim, Yeongkyoo; Park, Eungyu | Korea Inst Geosci & Mineral Resources KIGAM, Daejeon, South Korea; GeoGreen21, Seoul, South Korea; Kyungpook Natl Univ, Dept Geol, Daegu, South Korea | 57183819700; 58305515400; 7410207179; 23995577700 | egpark@knu.ac.kr; | SCIENCE OF THE TOTAL ENVIRONMENT | SCI TOTAL ENVIRON | 0048-9697 | 1879-1026 | 899 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.2 | 8.5 | 0.45 | 2025-06-25 | 3 | 5 | Groundwater quality; Trend analysis; Small watersheds; Data aggregation; Segmented robust regression; Adaptive groundwater management | ANTHROPOGENIC FACTORS; INTEGRATION; NITRATE; TREND | Adaptive groundwater management; Data aggregation; Groundwater quality; Segmented robust regression; Small watersheds; Trend analysis | South Korea; Data handling; Groundwater; Information analysis; Quality control; Water conservation; Water management; Water quality; ammonia; chloride; ground water; nitrate; nitrogen; sulfate; Adaptive groundwater management; Aggregated datum; Case-studies; Data aggregation; Groundwater management; Groundwater quality; Robust regressions; Segmented robust regression; Small watersheds; Trend analysis; business development; groundwater resource; public health; regression analysis; research work; trend analysis; water quality; watershed; Article; concentration (parameter); controlled study; data analysis; decision making; environmental monitoring; environmental policy; total quality management; water contamination; water depth; water management; water quality; watershed; Quality management | English | 2023 | 2023-11-15 | 10.1016/j.scitotenv.2023.165981 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Fe(II) activated calcium peroxide/peroxymonosulfate: A practical system for phenanthrene degradation and upholding ecological pH | Groundwater contamination by polycyclic aromatic hydrocarbons (PAHs) can have adverse effects on both the subsurface environment and human health. This study aimed to demonstrate the degradation of PHE using a coupled oxidant system, that involves simultaneous injection of Fe(II) and oxidants, CaO2 (CP) and peroxymonosulfate (PMS). To ensure the environmental compatibility, coupled oxidant strategy was proposed to maintain the pH level between 6.0 and 8.0 following the treatment process. The influence of reaction conditions including concentration of PMS, CP, and Fe(II) concentrations, initial pH, anions, and humic acid on PHE degradation were assessed. Scavenger experiments and electron spin resonance (ESR) analysis confirmed that hydroxyl radical (HO center dot-) and non-radical singlet oxygen (O-1(2)) were the primary reactive oxygen species (ROS) in the reported system. PHE degradation mechanism in the coupled oxidant system was proposed based on by-products identification. In addition, the CP/PMS/Fe(II) system showed promising degradation performance for naphthalene and pyrene, indicating the proposed strategy could be a viable option for removing a broad spectrum of PAHs. Finally, the coupled oxidant system was optimized to achieve best PHE removal efficiency under natural groundwater (NGW) conditions. | Masud, Md Abdullah Al; Kumar, Alam Venugopal Narendra; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | ; Masud, Md Abdullah Al/JEF-1055-2023 | 57542255300; 39262149400; 23019870800 | wshin@knu.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 317 | SCIE | ENGINEERING, CHEMICAL | 2023 | 8.2 | 8.5 | 2.18 | 2025-06-25 | 23 | 24 | Calcium peroxide; Coupled oxidant; Phenanthrene; Natural groundwater; Peroxymonosulfate | OXIDATION; PEROXYMONOSULFATE; PEROXIDE; HYDROXYL; SOIL | Calcium peroxide; Coupled oxidant; Natural groundwater; Peroxymonosulfate; Phenanthrene | Anthracene; Calcium compounds; Degradation; Electron spin resonance spectroscopy; Groundwater; Groundwater pollution; Iron compounds; Magnetic moments; Naphthalene; Oxidation; Oxygen; Peroxides; Adverse effect; Coupled oxidant; Groundwater contamination; Human health; Natural groundwater; Peroxymonosulfate; Phenanthrene; Practical systems; Simultaneous injections; Subsurface environment; Oxidants | English | 2023 | 2023-07-15 | 10.1016/j.seppur.2023.123902 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Highly-selective xenon-krypton separation using hydrate-based technology | Xenon (Xe) and krypton (Kr) are used in many important industries such as lighting, lasers, double glazing for insulation, and medicine. As Xe and Kr are found in extremely low concentrations in the atmosphere, only small quantities of the mixture of these gases are obtained as byproducts from air separation processes. As the further separation of Kr from Xe is achieved via a costly energy-intensive cryogenic distillation method, the development of a new cost-effective approach for Xe-Kr separation is essential. In this study, we demonstrated that clathrate hydrates can be used as a promising Xe trap to separate a Xe-Kr mixture and produce Kr-rich vapors. The Xe and Kr guest distributions in mixed clathrate hydrates were experimentally identified using powder X-ray diffraction, solid-state 129Xe NMR spectroscopy, and gas chromatography. The mixed Xe + Kr hydrates have a Pm3n structure, termed structure I (sI), regardless of the concentration of Xe in the feed vapor in the range of 3% to 100%, and the sI hydrate selectively captures Xe from the feed mixture. The phase equilibria of the mixed Xe + Kr hydrates were also investigated, and it was confirmed that the hydrate-based Xe-Kr separation process requires milder temperature conditions than the cryogenic distillation process. Overall, the findings in this work suggest that the hydrate-based Xe-Kr separation process is an excellent alternative to the energy-intensive cryogenic distillation method. | Chu, Hyunglok; Shin, Kyuchul | Kyungpook Natl Univ, Dept Appl Chem, 80 Daehak ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, 80 Daehak ro, Daegu 41566, South Korea | 58260621000; 14030501800 | kyuchul.shin@knu.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 319 | SCIE | ENGINEERING, CHEMICAL | 2023 | 8.2 | 8.5 | 0.36 | 2025-06-25 | 3 | 4 | Clathrate; Hydrate; Xenon; Krypton; Gas Separation | METAL-ORGANIC FRAMEWORK; ADSORPTIVE SEPARATION; ARGON KRYPTON; HIGH-PRESSURE; GAS; CRYSTAL; KINETICS; CAPTURE | Clathrate; Gas Separation; Hydrate; Krypton; Xenon | Distillation; Gas chromatography; Nuclear magnetic resonance spectroscopy; Phase equilibria; Xenon; Clathrate hydrate; Clathrates; Cryogenic distillations; Distillation method; Double glazings; Energy; Gas separations; Hydrate; Separation process; Xenon; Cost effectiveness | English | 2023 | 2023-08-15 | 10.1016/j.seppur.2023.124094 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Impact of microfiber pollution on aquatic biota: A critical analysis of effects and preventive measures | The widespread use of Personal protective equipments (PPEs) by the healthcare professionals and public due to Corona Virus Disease (COVID-19) pandemic has become a new source for MFs pollution. Mismanaged plastic wastes and ran -dom dispose of used surgical face mask end up in large aquatic bodies via small waterways and waste water treatment plants (WWTPs). Microplastics/Microfibres (MPs/MFs) have recently been reported in a variety of aquatic and terres-trial ecosystems, including water, deep sea sediments, air and soil. Natural components like UV radiation and temper-ature play a major role in weathering of surgical masks. High loads of MPs/MFs emitted into the aquatic environment are easily consumed by organism's habitat in such ecosystem by disrupting the food chain and causing chronic health problems in the organisms including humans. The aim of this review article is to shed light on these issues and compile the most recent information available regarding the deterioration of surgical face masks in the environment as well as other contaminants and their presence in various environments, particularly with regard to methods that make use of exposure models, biomarkers of exposure, and their limitations. Along with this, the study focuses on identifying gaps in current understanding and highlighting prospective research directions. The literature on surgical face mask pollu-tion and its effects on the biological and physiological systems of various organisms and ecosystems is critically analysed in this review. It also raises awareness of how to properly dispose of used surgical face masks and other PPEs. | Priya, K.

| ○ | ○ | Article | Polytetrafluorethylene microplastic particles mediated oxidative stress, inflammation, and intracellular signaling pathway alteration in human derived cell lines | Microplastics (MPs) are now widely distributed across the aerial, terrestrial, and aquatic environments. Thus, exposure to MPs via the oral, inhalation, or dermal routes is inevitable. Polytetrafluoroethylene (PTFE)-MPs is mainly used for manufacturing nonstick cookware, semiconductors, and medical devices; however, their toxicity has been rarely studied. In the present study, six different human cell lines, which are representative of tissues and cells that directly or indirectly come into contact with MPs, were exposed to two different sizes of irregular shape PTFE-MPs (with an average diameter of 6.0 or 31.7 & mu;m). PTFE-MPs-mediated cytotoxicity, oxidative stress, and changes in proinflammatory cytokine production were then evaluated. We found that the PTFE-MPs did not induce cytotoxicity under any of the experimental conditions. However, PTFE-MPs (especially average diameter of 6.0 & mu;m) induced nitric oxide and reactive oxygen species production in all the cell lines tested. Moreover, both sizes of PTFE-MPs increased the secretion of tumor necrosis factor alpha and interleukin-6 from the U937 macrophage cell line and the A549 lung epithelial cell line, respectively. In addition, PTFE-MPs activated the MAPK signaling pathways, especially the ERK pathway, in A549 and U937 cells, and in the THP-1 dendritic cell line. We also found that the expression of the NLRP3 inflammasome was reduced in the U937 and THP-1 cell lines following treatment with the PTFE-MPs sized 31.7 & mu;m average diameter. Furthermore, expression of the apoptosis regulator, BCL2, was markedly increased in the A549 and U937 cell | Bahadur, K. C.

| ○ | ○ | Review | Recent approaches and advanced wastewater treatment technologies for mitigating emerging microplastics contamination-A critical review | Microplastics have been identified as an emerging pollutant due to their irrefutable prevalence in air, soil, and partic-ularly, the aquatic ecosystem. Wastewater treatment plants (WWTPs) are seen as the last line of defense which creates a barrier between microplastics and the environment. These microplastics are discharged in large quantities into aquatic bodies due to their insufficient containment during water treatment. As a result, WWTPs are regarded as point sources of microplastics release into the environment. Assessing the prevalence and behavior of microplastics in WWTPs is therefore critical for their control. The removal efficiency of microplastics was 65 %, 0.2-14 %, and 0.2-2 % after the successful primary, secondary and tertiary treatment phases in WWTPs. In this review, other than conventional treatment methods, advanced treatment methods have also been discussed. For the removal of microplastics in the size range 20-190 mu m, advanced treatment methods like membrane bioreactors, rapid sand filtra-tion, electrocoagulation and photocatalytic degradation was found to be effective and these methods helps in increas-ing the removal efficiency to >99 %. Bioremediation based approaches has found that sea grasses, lugworm and blue mussels has the ability to mitigate microplastics by acting as a natural trap to the microplastics pollutants and could act as candidate species for possible incorporation in WWTPs. Also, there is a need for controlling the use and unchecked release of microplastics into the environment through laws and regulations. | Krishnan, Radhakrishnan Yedhu; Manikandan, Sivasubramanian; Subbaiya, Ramasamy; Karmegam, Natchimuthu; Kim, Woong; Govarthanan, Muthusamy | Amal Jyothi Coll Engn, Dept Food Technol, Kottayam 686518, Kerala, India; Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Dept Biotechnol, Chennai 602105, Tamil Nadu, India; Copperbelt Univ, Sch Math & Nat Sci, Dept Biol Sci, Jambo Dr,POB 2162, Kitwe, Zambia; Govt Arts Coll Autonomous, PG & Res Dept Bot, Salem 636007, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu, South Korea; Saveetha Inst Med & Tech Sci, Saveetha Dent Coll & Hosp, Dept Biomat, Chennai 600077, Tamil Nadu, India | ; S, Manikandan/GZM-7135-2022; Subbaiya, R/AAR-2948-2021; Govarthanan, Muthusamy/C-1491-2014; Muthusamy, Govarthanan/C-1491-2014; Natchimuthu, Karmegam/J-4745-2019; Krishnan, Radhakrishnan/K-7885-2016; Karmegam, Natchimuthu/J-4745-2019 | 57198186588; 55213168500; 55263515700; 6506043230; 55581636400; 54881927600 | kanishkarmegam@gmail.com;elshine@knu.ac.kr;gova.muthu@gmail.com; | SCIENCE OF THE TOTAL ENVIRONMENT | SCI TOTAL ENVIRON | 0048-9697 | 1879-1026 | 858 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.2 | 8.5 | 5.98 | 2025-06-25 | 159 | 181 | Microplastics; Wastewater treatment plants; Membrane technology; Bioremediation; Advanced techniques | ACTIVATED-SLUDGE PROCESS; HIGH-DENSITY POLYETHYLENE; MEMBRANE BIOREACTOR; TREATMENT PLANTS; DYNAMIC MEMBRANE; MARINE-ENVIRONMENT; REVERSE-OSMOSIS; SEWAGE-SLUDGE; REMOVAL; FATE | Advanced techniques; Bioremediation; Membrane technology; Microplastics; Wastewater treatment plants | Ecosystem; Environmental Monitoring; Environmental Pollutants; Microplastics; Plastics; Waste Disposal, Fluid; Waste Water; Water Pollutants, Chemical; Water Purification; Aquatic ecosystems; Biological water treatment; Bioreactors; Bioremediation; Efficiency; Laws and legislation; Membrane technology; Microfiltration; Microplastic; Reclamation; Sewage pumping plants; Water filtration; Water treatment plants; liposome; microplastic; microsphere; nanocomposite; polyhydroxyalkanoic acid; polyvinyl alcohol; plastic; Advanced technique; Advanced treatment; Air soils; Critical review; Emerging pollutants; Microplastics; Removal efficiencies; Treatment methods; Waste water treatment plants; Wastewater treatment technologies; bioremediation; critical analysis; plastic waste; point source; pollutant removal; wastewater treatment plant; adsorption; anaerobic digestion; aquaculture; aquatic environment; Arenicola marina; Aspergillus fumigatus; Bacillus cereus; Basidiomycetes; biodegradation; biofilm; bioremediation; biotransformation; chemical composition; contamination; cost effectiveness analysis; denitrification; electrocoagulation; electrolysis; emulsion; energy dispersive X ray spectroscopy; filtration; flocculation; gas chromatography; human; hydrophobicity; infrared spectroscopy; ion exchange chromatography; mass spectrometry; membrane technology; microalga; microbial community; microbial degradation; microbial diversity; microfiltration; microplastic pollution; municipal solid waste; mussel; nanofiltration; neurotoxicity; nonhuman; overall survival; oxidative stress; ozonation; Paenibacillus; particle image velocimetry; particle size; photocatalysis; phytotoxicity; polymerization; Proteobacteria; Pseudomonas putida; pyrolysis; recycling; Review; room temperature; scanning electron microscopy; seagrass; soil; soil acidity; solid waste management; transmission electron microscopy; waste water management; waste water treatment plant; wastewater; water pollution; X ray diffraction; Zygomycetes; ecosystem; environmental monitoring; pollutant; sewage; water management; water pollutant; Wastewater treatment | English | 2023 | 2023-02-01 | 10.1016/j.scitotenv.2022.159681 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
