| ○ | ○ | Article | Synchrotron, luminescence, and XPS studies of Gd³⁺:Dy³⁺:Ce³⁺ tri-rare-earth oxides in borate glasses | Synchrotron studies were employed to understand the oxidation state and coordination chemistry of the Ce3+ ions which when added with Dy3+- co-doped calcium zinc gadolinium borate glasses prepared by conventional melt quenching technique. X-ray photoelectron spectroscopy was employed to understand the coordination chemistry of the prepared glass samples. Detailed analysis was investigated to understand the glass's optical properties such as density, refractive index, molar volume, field strength, inter-ionic radius, and average boronboron distance. Using optical absorption studies, the Judd-Ofelt parameters were obtained, and radiative properties were evaluated and compared with other reported literature through the JO parameters. Photoluminescence and X-ray luminescence studies show similar results and found that the 575 nm corresponds to the electric-dipole transition of F-4(9/2) -> H-6(13/2). Asymmetry ratio (Y/B) was evaluated to understand their covalency around the rare-earth ion. Lifetime analysis for Dy3+ and Gd(3+ )ions were able to probe and analyzed with a comparison of other reported glasses. CIE chromaticity diagram was able to plot for the prepared glass samples to bring about the (x, y) significance which provides their color coordinate temperature (CCT) values and compared with other glasses. | Rajaramakrishna, R.; Kothan, S.; Busayaporn, W.; Chanlek, N.; Kim, H.

| ○ | Article | A novel encapsulation of 16 polycyclic aromatic hydrocarbons in petroleum sludge with palm oil fuel ash binder; an optimization study and sensitivity analysis using machine learning application | Palm oil fuel ash (POFA) has limited use as a fertilizer, while contribute effectively to the environmental contamination and health risks. Petroleum sludge poses a serious effect on the ecological environment and human health. The present work aimed to present a novel encapsulation process with POFA binder for treating petroleum sludge. Among 16 polycyclic aromatic hydrocarbons, four compounds were selected for the optimization of encapsulation process due to their high risk as carcinogenic substrates. Percentage PS (10–50%) and curing days (7–28 days) factors were used in the optimization process. The leaching test of PAHs was assessed using a GC-MS. The best operating parameters to minimize PAHs leaching from solidified cubes with OPC and10% POFA were recorded with 10% PS and after 28 days, at which PAH leaching was 4.255 and 0.388 ppm with R2 is 0.90%. Sensitivity analysis of the actual and predicted results for both the control and the test (OPC and 10% POFA) revealed that the actual results of the 10% POFA experiments have a high consistency with the predicted data (R2 0.9881) while R2 in the cement experiments was 0.8009. These differences were explained based on the responses of PAH leaching toward percentage of PS and days of cure. In the OPC encapsulation process, the main role was belonged to PS% (94.22%), while with 10% POFA, PS% contributed by 32.36 and cure day contributed by 66.91%. © 2023 Elsevier Ltd | Roslee, Noor Faiza; Kamil, Nor Amani Filzah Mohd; Alias, Salina; Senthil Kumar, P.; Alkhadher, Sadeq; Muthusamy, Govarthanan; Al-Gheethi, Adel | Faculty of Civil Engineering and Built Environment, Universiti Tun Hussien Onn Malaysia, Johor, Batu Pahat, Malaysia; Micro Pollutant Research Center, Universiti Tun Hussien Onn Malaysia, Johor, Batu Pahat, Malaysia; Centre for Civil Engineering Studies, Universiti Teknologi MARA, Cawangan Pulau Pinang, Permatang Pauh Branch, Seberang Prai, Pulau Pinang, Malaysia; Department of Chemical Engineering, Sri Sivasubramaniya Nadar College of Engineering, Kalavakkam, Tamil Nadu, 603110, India, Centre of Excellence in Water Research (CEWAR), Sri Sivasubramaniya Nadar College of Engineering, Kalavakkam, Tamil Nadu, 603110, India, School of Engineering, Lebanese American University, Byblos, Lebanon, Department of Biotechnology Engineering and Food Technology, Chandigarh University, Mohali, 140413, India; Institute of Oceanography and Environment, Universiti Malaysia Terengganu, Terengganu, Kuala Nerus, 21030, Malaysia; Department of Environmental Engineering, Kyungpook National University, Daegu, South Korea, Department of Biomaterials, Saveetha Dental College, and Hospital, Saveetha Institute of Medical and Technical Sciences, Chennai, 600 077, India; Faculty of Civil Engineering and Built Environment, Universiti Tun Hussien Onn Malaysia, Johor, Batu Pahat, Malaysia, Global Centre for Environmental Remediation (GCER), University of Newcastle and CRC for Contamination Assessment and Remediation of the Environment (CRC CARE), Newcastle, Australia | 57218896993; 41762279000; 6602523143; 24074610000; 56405495700; 54881927600; 57195533166 | adel@uthm.edu.my;noramani@uthm.edu.my; | Chemosphere | CHEMOSPHERE | 0045-6535 | 1879-1298 | 334 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 0.47 | 2025-06-25 | 4 | Leaching; Machine learning models; optimization; Palm oil fuel ash binder; Polycyclic aromatic hydrocarbons | Environmental Pollution; Humans; Palm Oil; Petroleum; Polycyclic Aromatic Hydrocarbons; Sewage; Aromatization; Curing; Gasoline; Health risks; Leaching; Machine learning; Mineral oils; Polycyclic aromatic hydrocarbons; Risk assessment; Sensitivity analysis; palm oil; petroleum; polycyclic aromatic hydrocarbon; palm oil; polycyclic aromatic hydrocarbon; Encapsulation process; Environmental contamination; Fuel ash; Leaching; Machine learning applications; Machine learning models; Optimisations; Optimization studies; Palm oil fuel ash binder; Petroleum sludge; encapsulation; leaching; machine learning; optimization; PAH; sensitivity analysis; solid waste; Article; chemical composition; chemical reaction; compressive strength; controlled study; data availability; dependent variable; encapsulation; human; liquid liquid extraction; machine learning; mass fragmentography; maximum permissible dose; particle size; sensitivity analysis; Soxhlet extraction; chemistry; pollution; sewage; Palm oil | English | Final | 2023 | 10.1016/j.chemosphere.2023.139037 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | A polymer library enables the rapid identification of a highly scalable and efficient donor material for organic solar cells | The dramatic improvement of the PCE (power conversion efficiency) of organic photovoltaic devices in the past few years has been driven by the development of new polymer donor materials and non-fullerene acceptors (NFAs). In the design of such materials synthetic scalability is often not considered, and hence complicated synthetic protocols are typical for high-performing materials. Here we report an approach to readily introduce a variety of solubilizing groups into a benzo[c][1,2,5]thiadiazole acceptor comonomer. This allowed for the ready preparation of a library of eleven donor polymers of varying side chains and comonomers, which facilitated a rapid screening of properties and photovoltaic device performance. Donor FO6-T emerged as the optimal material, exhibiting good solubility in chlorinated and non-chlorinated solvents and achieving 15.4% PCE with L8BO as the acceptor (15.2% with Y6) and good device stability. FO6-T was readily prepared on the gram scale, and synthetic complexity (SC) analysis highlighted FO6-T as an attractive donor polymer for potential large scale applications. | Rimmele, Martina; Qiao, Zhuoran; Panidi, Julianna; Furlan, Francesco; Lee, Chulyeon; Tan, Wen Liang; McNeill, Christopher R.; Kim, Youngkyoo; Gasparini, Nicola; Heeney, Martin | Imperial Coll London, Dept Chem, London W12 0BZ, England; Imperial Coll London, Ctr Processable Elect, London W12 0BZ, England; Kyungpook Natl Univ, Organ Nanoelect Lab, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Inst Nanophoton Applicat KINPA, Sch Appl Chem Engn, Dept Chem Engn, Daegu 41566, South Korea; Monash Univ, Dept Mat Sci & Engn, Wellington Rd, Clayton, Vic 3800, Australia; King Abdullah Univ Sci & Technol KAUST, KAUST Solar Ctr KSC, Phys Sci & Engn Div PSE, Thuwal 239556900, Saudi Arabia | ; Heeney, Martin/O-1916-2013; Panidi, Julianna/AAD-2125-2020; McNeill, Christopher/B-4530-2008; tan, wen/KUF-0511-2024; Gasparini, Nicola/T-8609-2019; Rimmele, Martina/KLD-4184-2024 | 57213933623; 57397738500; 57200299947; 57219339703; 56354831300; 57204354178; 8557588500; 10340424400; 56446726400; 6701353187 | n.gasparini@imperial.ac.uk;martin.heeney@kaust.edu.sa; | MATERIALS HORIZONS | MATER HORIZ | 2051-6347 | 2051-6355 | 10 | 10 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 12.2 | 8.8 | 1.14 | 2025-06-25 | 10 | 10 | BANDGAP CONJUGATED POLYMER; OPTOELECTRONIC PROPERTIES; PHOTOVOLTAIC APPLICATIONS; CHAIN MODIFICATION; RATIONAL DESIGN; RECENT PROGRESS; PERFORMANCE; ENERGY; MORPHOLOGY; RECOMBINATION | Conversion efficiency; 5]thiadiazole; Comonomers; Donor materials; Organic photovoltaic devices; Polymer libraries; Power conversion efficiencies; Rapid identification; Rapid screening; Side-chains; Synthetic protocols; Organic solar cells | English | 2023 | 2023-10-02 | 10.1039/d3mh00787a | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Artificial neural network implementation for dissolved organic carbon quantification using fluorescence intensity as a predictor in wastewater treatment plants | Although spectroscopic methods provide a fast and cost-effective means of monitoring dissolved organic carbon (DOC) in natural and engineered water systems, the prediction accuracy of these methods is limited by the complex relationship between optical properties and DOC concentration. In this study, we developed DOC prediction models using multiple linear/log-linear regression and feedforward artificial neural network (ANN) and investigated the effectiveness of spectroscopic properties, such as fluorescence intensity and UV absorption at 254 nm (UV254), as predictors. Optimum predictors were identified based on correlation analysis to construct models using single and multiple predictors. We compared the peak-picking and parallel factor analysis (PARAFAC) methods for selecting appropriate fluorescence wavelengths. Both methods had similar prediction capability (p-values >0.05), suggesting PARAFAC was not necessary for choosing fluorescence predictors. Fluorescence peak T was identified as a more accurate predictor than UV254. Combining UV254 and multiple fluorescence peak intensities as predictors further improved the prediction capability of the models. The ANN models outperformed the linear/log-linear regression models with multiple predictors, achieving higher prediction accuracy (peak-picking: R2 = 0.8978, RMSE = 0.3105 mg/L; PARAFAC: R2 = 0.9079, RMSE = 0.2989 mg/L). These findings suggest the potential to develop a real-time DOC concentration sensor based on optical properties using an ANN for signal processing. © 2023 Elsevier Ltd | Nurhayati, Mita; You, Youngmin; Park, Jongkwan; Lee, Byung Joon; Kang, Ho Geun; Lee, Sungyun | Department of Advanced Science and Technology Convergence, Kyungpook National University, 2559 Gyeongsang-daero, Sangju-si, 37224, South Korea, Department of Chemistry, Indonesia University of Education, Setiabudhi 229, Bandung, 40154, Indonesia; Department of Advanced Science and Technology Convergence, Kyungpook National University, 2559 Gyeongsang-daero, Sangju-si, 37224, South Korea; School of Civil, Environmental and Chemical Engineering, Changwon National University, Gyeongsangnamdo, Changwon, 51140, South Korea; Department of Environmental and Safety Engineering, Kyungpook National University, 2559 Gyeongsang-daero, Sangju-si, 37224, South Korea; BIN-TECH KOREA Co., Ltd., A 3S52, 158-10, Sajik-daero 361beon-gil, Sangdang-gu, Chungcheongbuk-do, Cheongju-si, South Korea; Department of Advanced Science and Technology Convergence, Kyungpook National University, 2559 Gyeongsang-daero, Sangju-si, 37224, South Korea, Department of Environmental and Safety Engineering, Kyungpook National University, 2559 Gyeongsang-daero, Sangju-si, 37224, South Korea | 57222139830; 58303037600; 56969869700; 56016052400; 58303400900; 36438267000 | sungyunlee@knu.ac.kr; | Chemosphere | CHEMOSPHERE | 0045-6535 | 1879-1298 | 335 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 0.83 | 2025-06-25 | 7 | ANN; DOC; PARAFAC; Peak-picking; Prediction accuracy; UV<sub>254</sub> | Dissolved Organic Matter; Spectrometry, Fluorescence; Water; Water Pollutants, Chemical; Water Purification; Absorption spectroscopy; Cost effectiveness; Fluorescence; Optical properties; Organic carbon; Signal processing; Spectroscopic analysis; Wastewater treatment; organic carbon; dissolved organic matter; water; Carbon concentrations; Dissolved organic carbon; Fluorescence intensities; Fluorescence peak; Parallel factor analysis; Peak picking; Prediction accuracy; Prediction capability; Spectroscopic method; Waste water treatment plants; artificial neural network; dissolved organic carbon; fluorescence; signal processing; ultraviolet radiation; wastewater; wastewater treatment; Article; biodegradation; calibration; conductance; feed forward neural network; fluorescence intensity; inner filter effect; light absorption; measurement accuracy; optical sensor; parallel factor analysis; pH; prediction; temperature; turbidity; waste water treatment plant; water quality; procedures; spectrofluorometry; water management; water pollutant; Forecasting | English | Final | 2023 | 10.1016/j.chemosphere.2023.139032 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | Article | Bioaccumulation and in vivo fate of toxic benzylalkyldimethylammonium chloride in rats via the radiotracer analysis | Benzylalkyldimethylammonium chloride (BAC), a quaternary ammonium compound (QAC), is utilized in industrial and biomedical applications for antimicrobial purposes. Since the coronavirus disease (COVID-19) outbreak, various types of BAC-containing household chemicals have been produced. BACs have several adverse effects; however, their biological uptake, translocation, and excretion in animal models (essential for better understanding in vivo behavior and toxicological impact) remain unclear. In this study, we performed the first biodistribution and whole-body imaging studies of BAC in male Sprague Dawley rats, using two different administration routes. Quantitative whole-body autoradiography (QWBA) data obtained for intranasal 14C-labeled BAC ([14C]C12-BAC) exposure showed substantial uptake values for the respiratory organs (e.g. 346 ng g−1 of lung at 3 h post administration) and the radiotracer was transported to other internal organs. The amount of radiotracer in the heart, adrenal gland, and pancreas were 198, 1410, and 186 ng g−1 tissue respectively at 168 h following exposure. Autoradiograms obtained after intravenous injection also showed high accumulation and slow excretion in these organs. The cumulative excretion analysis revealed that approximately 6.4% of the administered radioactivity remained in rats after a week. The results indicated that continuous inhalation exposure to BAC leads to potential toxic effects in extrapulmonary organs and the respiratory tract. Thus, the radiolabeling method utilized may help assess various synthetic QACs in living subjects. © 2023 The Authors | Park, Jung Eun; Ryu, Seung-Hun; Ito, Satoshi; Song, Mi-Kyung; Gu, Eun Ji; Shin, Hyunil; Kim, Young-Hee; Jeon, Jongho | Department of Applied Chemistry, College of Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Humidifier Disinfectant Health Center, Environmental Health Research Department, National Institute of Environmental Research, 42 Hwangyong-ro, Seo-gu, Incheon, 22689, South Korea; Drug Development Solutions Center, Sekisui Medical Co., Ltd., 2117 Muramatsu, Ibaraki, Tokai, 319-1182, Japan; Inhalation Toxicology Center for Airborne Risk Factor, Korea Institute of Toxicology, 30 Baehak1-gil, Jeollabuk-do, Jeongeup, 56212, South Korea; Department of Applied Chemistry, College of Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; KRCC Co., Ltd, 193 Chenggyesan-ro, Seocho-gu, Seoul, 06802, South Korea; Humidifier Disinfectant Health Center, Environmental Health Research Department, National Institute of Environmental Research, 42 Hwangyong-ro, Seo-gu, Incheon, 22689, South Korea; Department of Applied Chemistry, College of Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea | 57210160353; 57928816900; 58485447600; 42262783500; 58485447700; 57928786800; 55699593700; 35082028100 | jeonj@knu.ac.kr; | Chemosphere | CHEMOSPHERE | 0045-6535 | 1879-1298 | 338 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 0.71 | 2025-06-25 | 6 | Benzylalkyldimethylammonium chloride; Biological uptake; In vivo assessment; Quantitative whole-body autoradiography; Radiotracer | Animals; Bioaccumulation; Chlorides; COVID-19; Male; Rats; Rats, Sprague-Dawley; Tissue Distribution; Biochemistry; Chlorine compounds; Coronavirus; Medical applications; Radioactive tracers; Radiography; benzylalkyldimethylammonium chloride; domestic chemical; quaternary ammonium derivative; tracer; unclassified drug; chloride; Benzylalkyldimethylammonium chloride; Biological uptake; Biomedical applications; Coronaviruses; In vivo assessment; In-vivo; Quantitative whole-body autoradiography; Quaternary ammonium compound; Radiotracer; Whole-body; ammonium compound; assessment method; bioaccumulation; biological uptake; quantitative analysis; radioactivity; rodent; tracer; adrenal gland; animal experiment; animal model; Article; autoradiography; bioaccumulation; controlled study; coronavirus disease 2019; exposure; heart; high performance liquid chromatography; in vivo study; liquid scintillation counting; lung; male; mass spectrometry; metabolic fingerprinting; nonhuman; nuclear magnetic resonance; pancreas; proton nuclear magnetic resonance; radioactivity; radiochemistry; radiochromatography; radiolabeling; rat; risk assessment; Sprague Dawley rat; whole body autoradiography; whole body imaging; animal; bioaccumulation; coronavirus disease 2019; tissue distribution; Rats | English | Final | 2023 | 10.1016/j.chemosphere.2023.139460 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Review | Biological and green remediation of heavy metal contaminated water and soils: A state-of-the-art review | Contamination of the natural ecosystem by heavy metals, organic pollutants, and hazardous waste severely impacts on health and survival of humans, animals, plants, and microorganisms. Diverse chemical and physical treatments are employed in many countries, however, the acceptance of these treatments are usually poor because of taking longer time, high cost, and ineffectiveness in contaminated areas with a very high level of metal contents. Bioremediation is an eco-friendly and efficient method of reclaiming contaminated soils and waters with heavy metals through biological mechanisms using potential microorganisms and plant species. Considering the high efficacy, low cost, and abundant availability of biological materials, particularly bacteria, algae, yeasts, and fungi, either in natural or genetically engineered (GE) form, bioremediation is receiving high attention for heavy metal removal. This report comprehensively reviews and critically discusses the biological and green remediation tactics, contemporary technological advances, and their principal applications either in -situ or ex-situ for the remediation of heavy metal contamination in soil and water. A modified PRISMA review protocol is adapted to critically assess the existing research gaps in heavy metals remediation using green and biological drivers. This study pioneers a schematic illustration of the underlying mechanisms of heavy metal bioremediation. Precisely, it pinpoints the research bottleneck during its real-world application as a low-cost and sustainable technology. | Sarker, Aniruddha; Al Masud, Md Abdullah; Deepo, Deen Mohammad; Das, Kallol; Nandi, Rakhi; Ansary, Most Waheda Rahman; Islam, Abu Reza Md Towfiqul; Islam, Tofazzal | Rural Dev Adm, Natl Inst Agr Sci, Residual Chem Assessment Div, Jeollabuk 55365, Jeonrabug Do, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Agr & Life Sci, Daegu 41566, South Korea; Bangladesh Acad Rural Dev BARD, Cumilla, Bangladesh; Bangabandhu Sheikh Mujibur Rahman Agr Univ, Inst Biotechnol & Genet Engn IBGE, Gazipur 1706, Bangladesh; Begum Rokeya Univ, Dept Disaster Management, Rangpur 5400, Bangladesh; Daffodil Int Univ, Dept Dev Studies, Dhaka 1216, Bangladesh | Sarker, Aniruddha/GYQ-6800-2022; Islam, Tofazzal/F-2563-2010; Das, Kallol/AAR-6707-2020; Islam, Abu Reza Md.

| ○ | ○ | Article | Bioprospecting of novel peroxidase from Streptomyces coelicolor strain SPR7 for carcinogenic azo dyes decolorization | Peroxidase (POX) is a heme-containing oxidoreductase, its voluminous immuno-diagnostic and bioremediatory intuitions have incited optimization and large scale-generation from novel microbial repertoires. Azo dyes are the most detrimental classes of synthetic dyes and they are the common ecotoxic industrial pollutants in wastewater. In addition, azo dyes are refractory to degradation owing to their chemical nature, comprising of azoic linkages, amino moieties with recalcitrant traits. Moreover, they are major carcinogenic and mutagenic on humans and animals, whereby emphasizing the need for decolorization. In the present study, a novel POX from Streptomyces coelicolor strain SPR7 was investigated for the deterioration of ecotoxic dyestuffs. The initial me-dium component screening for POX production was achieved using, One Factor at a Time and Placket-Burman methodologies with starch, casein and temperature as essential parameters. In auxiliary, Response Surface Methodology (RSM) was recruited and followed by model validation using Back propagation algorithm (BPA). RSM-BPA composite approach prophesied that combination of starch, casein, and temperature at optimal values 2.5%, 0.035% and 35 degrees C respectively, has resulted in 7 folds enhancement of POX outturn (2.52 U/mL) compared to the unoptimized media (0.36 U/mL). The concentrated enzyme decolorized 75.4% and 90% of the two azo dyes with lignin (10 mM), respectively.

| ○ | ○ | Review | Carbon-based nanomaterial intervention and efficient removal of various contaminants from effluents - A review | Water treatment is a worldwide issue. This review aims to present current problems and future challenges in water treatments with the existing methodologies. Carbon nanotube production, characterization, and pro-spective uses have been the subject of considerable and rigorous research around the world. They have a large number of technical uses because of their distinct physical characteristics. Various catalyst materials are used to make carbon nanotubes. This review's primary focus is on integrated and single-treatment technologies for all kinds of drinking water resources, including ground and surface water. Inorganic non-metallic matter, heavy metals, natural organic matter, endocrine-disrupting chemicals, disinfection by-products and microbiological pollutants are among the contaminants that these treatment systems can remediate in polluted drinking water resources. Significant advances in the antibacterial and adsorption capabilities of carbon-based nanomaterials have opened up new options for excluding organic/inorganic and biological contaminants from drinking water in recent years. The advancements in multifunctional nanocomposites synthesis pave the possibility for their use in enhanced wastewater purification system design. The adsorptive and antibacterial characteristics of six main kinds of carbon nanomaterials are single-walled carbon nanotubes, multi-walled carbon nanotubes, graphene, graphene oxide, fullerene and single-walled carbon nanohorns. This review potentially addressed the essential metallic and polymeric nanocomposites, are described and compared. Barriers to use these nanoparticles in long-term water treatment are also discussed. | Manimegalai, Sengani; Vickram, Sundaram; Deena, Santhana Raj; Rohini, Karunakaran; Thanigaivel, Sundaram; Manikandan, S.; Subbaiya, R.; Karmegam, N.; Kim, Woong; Govarthanan, M. | SRM Inst Sci & Technol, Coll Sci & Humanities, Dept Biotechnol, Chennai 600087, India; Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Dept Biotechnol, Chennai 602105, Tamil Nadu, India; AIMST Univ, Fac Med, Unit Biochem, Bedong, Malaysia; SRM Inst Sci & Technol, Fac Sci & Humanities, Dept Biotechnol, Kattankulathur 603203, Tamil Nadu, India; Copperbelt Univ, Sch Math & Nat Sci, Dept Biol Sci, Jambo Dr,POB 21692, Kitwe, Zambia; Govt Arts Coll Autonomous, PG & Res Dept Bot, Salem 636007, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Saveetha Inst Med & Tech Sci, Saveetha Dent Coll & Hosp, Dept Biomat, Chennai 600077, India; Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Dept Bioinformat, Chennai 602105, Tamil Nadu, India | ; Muthusamy, Govarthanan/C-1491-2014; Natchimuthu, Karmegam/J-4745-2019; Subbaiya, R/AAR-2948-2021; Santhana RaJ, Deena/HGV-5071-2022; S, Vickram/ABG-9459-2020; Karunakaran, Rohini/ABE-6709-2020; S, Manikandan/GZM-7135-2022; Segani, Manimegalai/GMW-5494-2022; Govarthanan, Muthusamy/C-1491-2014; Karmegam, Natchimuthu/J-4745-2019; Santhana Raj, Deena/HGV-5071-2022 | 57996889800; 55257689800; 57772435200; 59886171900; 55624925900; 55213168500; 55263515700; 6506043230; 55581636400; 54881927600 | kanishkarmegam@gmail.com;elshine@knu.ac.kr;gova.muthu@gmail.com; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 312 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 9.67 | 2025-06-25 | 54 | 82 | Carbon nanotubes; Contaminants; Endocrine disrupting chemicals; Graphene oxide; Wastewater treatment | GRAPHENE OXIDE; WATER; NANOTUBES; MEMBRANES; FUNCTIONALIZATION; NANOPARTICLES; CHALLENGES; FILTRATION; DISPERSION; COMPOSITE | Carbon nanotubes; Contaminants; Endocrine disrupting chemicals; Graphene oxide; Wastewater treatment | Adsorption; Anti-Bacterial Agents; Drinking Water; Nanocomposites; Nanotubes, Carbon; Wastewater; Water Pollutants, Chemical; Water Purification; Chemicals removal (water treatment); Effluents; Endocrine disrupters; Graphene; Heavy metals; Impurities; Multiwalled carbon nanotubes (MWCN); Nanocomposites; Organic chemicals; Potable water; Single-walled carbon nanotubes (SWCN); Surface waters; Water pollution; carbon nanoparticle; carbon nanotube; disinfectant agent; dissolved organic matter; drinking water; endocrine disruptor; fullerene derivative; graphene; graphene oxide; ground water; heavy metal; multi walled nanotube; nanocomposite; natural organic matter; single walled nanotube; surface water; antiinfective agent; carbon nanotube; drinking water; nanocomposite; wastewater; Antibacterials; Carbon-based; Current problems; Drinking water resources; Endocrine disrupting chemicals; Future challenges; Graphene oxides; Nanotube production; Prospectives; Rigorous research; carbon nanotube; effluent; endocrine disruptor; nanomaterial; pollutant; wastewater; wastewater treatment; water treatment; Article; effluent; nanotechnology; waste component removal; waste water management; water contamination; water filtration; adsorption; chemistry; procedures; wastewater; water management; water pollutant; Wastewater treatment | English | 2023 | 2023-01 | 10.1016/j.chemosphere.2022.137319 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Degradation of phenol by ball-milled activated carbon (ACBM) activated dual oxidant (persulfate/calcium peroxide) system: Effect of preadsorption and sequential injection | This study explored pre-adsorption and sequential injection of dual oxidant (DuOx) of persulfate (PS) and calcium peroxide (CP) for phenol degradation in an aqueous solution. Ball-milled activated carbon (AC(BM)) was used as the catalyst in the following systems: pre-adsorption and sequential injection of PS and CP (AC(BM) + PS + CP), pre-adsorption and simultaneous injection of PS and CP (AC(BM) + PS/CP), simultaneous injection of AC(BM), PS, and CP (AC(BM)/PS/CP), simultaneous injection of AC(BM) and PS (AC(BM)/PS), and simultaneous injection of AC(BM) and CP (AC(BM)/CP). The AC(BM)had a larger specific surface area, more graphitic structures, and more defects. Moreover, it showed better phenol removal when introduced simultaneously with PS and CP. The phenol removal was most the efficient in AC(BM) + PS + CP (98.8%) with a near-neutral final pH, followed by AC(BM) + PS/CP, AC(BM)/PS, AC(BM)/PS/CP, and AC(BM)/CP. This indicates that pre-adsorption and separate injection of PS and CP were the key strategy for improved performance and maintained favorable pH for the activation of PS and CP. The dual oxidant system (PS/CP) is superior to single oxidant systems (PS or CP). Scavenger experiments and the electron spin resonance spectra (ESR) demonstrated that non-radical species (O-1(2)) were dominantly involved in AC(BM) + PS + CP, but radical species (HO center dot, SO4 center dot-) also contributed. HCO3- and HPO42- inhibited phenol degradation in AC(BM) + PS + CP, whereas Cl- and HA had negligible effects. The AC(BM) + PS + CP showed high total organic carbon removal and AC(BM) was recyclable with a slight decrease in activity. This work is important as it provides a detailed insight into the strategy of pre-adsorption and sequential injection of dual oxidants for a practical and cost-effective method of groundwater remediation. | Al Masud, Md Abdullah; Shin, Won Sik; Kim, Do Gun | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Sunchon Natl Univ, Dept Environm Engn, Sunchon 57922, Jeonranam Do, South Korea | Masud, Md Abdullah Al/JEF-1055-2023 | 57542255300; 23019870800; 36623899900 | wshin@knu.ac.kr;dgkim@scnu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 312 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 2.83 | 2025-06-25 | 24 | 24 | Ball-milled activated carbon; Calcium peroxide; Dual oxidant; Persulfate; Pre-adsorption; Sequential injection | ADVANCED OXIDATION PROCESSES; HYDROGEN-PEROXIDE; SINGLET OXYGEN; ADSORPTION; RADICALS; GRAPHENE; CARBOCATALYSTS; GENERATION; CATALYSTS; FIBERS | Ball-milled activated carbon; Calcium peroxide; Dual oxidant; Persulfate; Pre-adsorption; Sequential injection | Charcoal; Oxidants; Oxidation-Reduction; Phenol; Phenols; Water Pollutants, Chemical; Activated carbon; Adsorption; Biodegradation; Calcium compounds; Cost effectiveness; Electron spin resonance spectroscopy; Groundwater; Magnetic moments; Organic carbon; Oxidants; Peroxides; Phenols; activated carbon; humic acid; phenol derivative; calcium peroxide; charcoal; oxidizing agent; phenol; phenol derivative; Ball-milled; Ball-milled activated carbon; Calcium peroxides; Dual oxidant; Persulphate; Phenol degradation; Phenols removal; Pre-adsorption; Sequential injection; Simultaneous injections; activated carbon; adsorption; degradation; inorganic compound; milling; oxidant; phenol; adsorption; adsorption kinetics; aqueous solution; Article; catalyst; controlled study; cost effectiveness analysis; degradation; electron spin resonance; oxidation; physical chemistry; rate constant; surface area; total organic carbon; chemistry; oxidation reduction reaction; water pollutant; Oxidation | English | 2023 | 2023-01 | 10.1016/j.chemosphere.2022.137120 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Ecological disturbances and abundance of anthropogenic pollutants in the aquatic ecosystem: Critical review of impact assessment on the aquatic animals | Anthropogenic toxins are discharged into the environment and distributed through a variety of environmental matrices. Trace contaminant detection and analysis has advanced dramatically in recent decades, necessitating further specialized technique development. These pollutants can be mobile and persistent in small amounts in the environment, and ecological receptors will interact with it. Despite the fact that few researches have been undertaken on invertebrate exposure, accumulation, and biological implications, it is apparent that a wide range of pollutants can accumulate in the tissues of aquatic insects, earthworms, amphipod crustaceans, and mollusks. Due to long-term stability during long-distance transit, a number of chemical and microbiological agents that were not previously deemed pollutants have been found in various environmental compartments. The uptake of such pollutants by the aquatic organism is done through the process of bioaccumulation when dangerous compounds accumulate in living beings while biomagnification is the process of a pollutant becoming more hazardous as it moves up the trophic chain. Organic and metal pollution harms animals of every species studied so far, from bacteria to phyla in between. The environmental protection agency says these poisons harm humans as well as a variety of aquatic organisms when the water quality is sacrificed in typical wastewater treatment systems. Contrary to popular belief, treated effluents discharged into aquatic bodies contain considerable levels of Anthropogenic contaminants. This evolution necessitates a more robust and recent advancement in the field of remediation and their techniques to completely discharge the various organic and inorganic contaminants. | Thanigaivel, Sundaram; Vickram, Sundaram; Dey, Nibedita; Jeyanthi, Palanivelu; Subbaiya, Ramasamy; Kim, Woong; Govarthanan, Muthusamy; Karmegam, Natchimuthu | SRM Inst Sci & Technol, Fac Sci & Humanities, Dept Biotechnol, Kattankulathur 603203, Tamil Nadu, India; Saveetha Inst Med & Tech Sci SIMATS, Chennai 602105, Tamil Nadu, India; Vel Tech Rangarajan Dr Sagunthala R&D Inst Science, Dept Biotechnol, Vel Tech Rangarajan Dr, Chennai 600062, India; Copperbelt Univ, Sch Math & Nat Sci, Dept Biol Sci, Jambo Dr,POB 21692, Kitwe, Zambia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Govt Arts Coll Autonomous, PG & Res Dept Bot, Salem 636007, Tamil Nadu, India | S, Vickram/ABG-9459-2020; Natchimuthu, Karmegam/J-4745-2019; Karmegam, Natchimuthu/J-4745-2019; Muthusamy, Govarthanan/C-1491-2014; Palanivelu, Jeyanthi/AAY-6023-2021; dey, nibedita/AAG-6776-2021; Govarthanan, Muthusamy/C-1491-2014; Subbaiya, R/AAR-2948-2021 | 55624925900; 55257689800; 57216549253; 56800907000; 55263515700; 55581636400; 54881927600; 6506043230 | elshine@knu.ac.kr;kanishkarmegam@gmail.com; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 313 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 6.49 | 2025-06-25 | 43 | 57 | Anthropogenic toxins; Aquatic animals; Environmental matrix; Life cycle assessment; Microplastics | LIFE-CYCLE ASSESSMENT; SURFACE WATERS; MARINE; BIOTECHNOLOGY; MICROPLASTICS; ENVIRONMENTS; DEGRADATION; HERBICIDES; REGIONS; SYSTEMS | Anthropogenic toxins; Aquatic animals; Environmental matrix; Life cycle assessment; Microplastics | Animals; Aquatic Organisms; Ecosystem; Environmental Monitoring; Environmental Pollutants; Humans; Water Pollutants, Chemical; Water Quality; Aquatic ecosystems; Aquatic organisms; Biochemistry; Chemical stability; Effluents; Environmental Protection Agency; Metabolites; Wastewater treatment; Water pollution; Water quality; antiinfective agent; chemical compound; heavy metal; microplastic; organic compound; poison; toxin; Anthropogenic pollutants; Anthropogenic toxin; Anthropogenics; Aquatic animals; Critical review; Ecological disturbance; Environmental matrixes; Impact assessments; Life cycle assessment; Microplastics; abundance; anthropogenic source; aquatic ecosystem; aquatic organism; ecological impact; environmental protection; life cycle analysis; plastic; toxin; Amphipoda; aquatic environment; aquatic species; Article; bioaccumulation; earthworm; effluent; environmental change; environmental impact assessment; environmental protection; environmental risk; environmental stress; environmental sustainability; greenhouse effect; human; human impact (environment); insect; life cycle assessment; mollusc; nonhuman; threat; waste water management; water contamination; water pollutant; water quality; animal; ecosystem; environmental monitoring; pollutant; procedures; Life cycle | English | 2023 | 2023-02 | 10.1016/j.chemosphere.2022.137475 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhanced bio-electrochemical performance of microbially catalysed anode and cathode in a microbial electrosynthesis system | Most bio-electrochemical systems (BESs) use biotic/abiotic electrode combinations, with platinum-based abiotic electrodes being the most common. However, the non-renewability, cost, and poisonous nature of such electrode systems based on noble metals are major bottlenecks in BES commercialisation. Microbial electrosynthesis (MES), which is a sustainable energy platform that simultaneously treats wastewater and produces chemical commodities, also faces the same problem. In this study, a dual bio-catalysed MES system with a biotic anode and cathode (MES-D) was tested and compared with a biotic cathode/abiotic anode system (MES-S). Different bio-electrochemical tests revealed improved BES performance in MES-D, with a 3.9-fold improvement in current density compared to that of MES-S. Volatile fatty acid (VFA) generation also increased 3.2-, 4.1-, and 1.8-fold in MES-D compared with that in MES-S for acetate, propionate, and butyrate, respectively. The improved perfor-mance of MES-D could be attributed to the microbial metabolism at the bioanode, which generated additional electrons, as well as accumulative VFA production by both the bioanode and biocathode chambers. Microbial community analysis revealed the enrichment of electroactive bacteria such as Proteobacteria (60%), Bacter-oidetes (67%), and Firmicutes + Proteobacteria + Bacteroidetes (75%) on the MES-S cathode and MES-D cathode and anode, respectively. These results signify the potential of combined bioanode/biocathode BESs such as MES for application in improving energy and chemical commodity production. | Tahir, Khurram; Ali, Abdul Samee; Ghani, Ahsan Abdul; Hussain, Muzammil; Kim, Bolam; Lim, Youngsu; Lee, Dae Sung | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; Tahir, Khurram/KFS-5321-2024 | 57207114377; 58073888400; 57218294089; 58279975000; 57208922438; 57207112603; 55568524907 | daesung@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 317 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 1.53 | 2025-06-25 | 14 | 13 | Dual bio-catalysed system; Bioanode; Biocathode; Microbial electrosynthesis system; Volatile fatty acid | FUEL-CELL; BIOCATHODE; ACETATE; ELECTRICITY; GENERATION; REDUCTION | Bioanode; Biocathode; Dual bio-catalysed system; Microbial electrosynthesis system; Volatile fatty acid | Acetates; Carbon Dioxide; Electrodes; Fatty Acids, Volatile; Wastewater; Anodes; Catalysis; Electrochemical electrodes; Metabolism; Volatile fatty acids; Wastewater treatment; acetic acid; butyric acid; phosphate; potassium ferricyanide; propionic acid; RNA 16S; volatile fatty acid; acetic acid; BES; carbon dioxide; volatile fatty acid; Bacteroidetes; Bio-electrochemical; Bio-electrochemical systems; Bioanode; Biocathodes; Biotics; Chemical commodities; Dual bio-catalyzed system; Microbial electrosynthesis system; Proteobacteria; alternative energy; electrode; fatty acid; metabolism; performance assessment; wastewater; wastewater treatment; Article; Bacteroidetes; carbon source; catalyst; controlled study; current density; cyclic voltammetry; electrosynthesis; Firmicutes; impedance spectroscopy; microbial community; microbial growth; microbial metabolism; nonhuman; Proteobacteria; waste water management; electrode; metabolism; wastewater; Cathodes | English | 2023 | 2023-03 | 10.1016/j.chemosphere.2023.137770 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhanced biodegradation of perfluorooctanoic acid in a dual biocatalyzed microbial electrosynthesis system | The toxic perfluorooctanoic acid (PFOA) is widely spread in terrestrial and aquatic habitats owing to its resistance to conventional degradation processes. Advanced techniques to degrade PFOA requires drastic conditions with high energy cost. In this study, we investigated PFOA biodegradation in a simple dual biocatalyzed microbial electrosynthesis system (MES). Different PFOA loadings (1, 5, and 10 ppm) were tested and a biodegradation of 91% was observed within 120 h. Propionate production improved and short-carbon-chain PFOA intermediates were detected, which confirmed PFOA biodegradation. However, the current density decreased, indicating an inhibitory effect of PFOA. High-throughput biofilm analysis revealed that PFOA regulated the microbial flora. Microbial community analysis showed enrichment of the more resilient and PFOA adaptive microbes, including Methanosarcina and Petrimonas. Our study promotes the potential use of dual biocatalyzed MES system as an environment-friendly and inexpensive method to remediate PFOA and provides a new direction for bioremediation research. | Tahir, Khurram; Ali, Abdul Samee; Kim, Jinseob; Park, Juhui; Lee, Seongju; Kim, Bolam; Lim, Youngsu; Kim, Gyuhyeon; Lee, Dae Sung | Univ Nova Lisboa, Inst Tecnol Quim & Biol Antonio Xavier, P-2780157 Oeiras, Portugal; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; Tahir, Khurram/KFS-5321-2024 | 57207114377; 58073888400; 58168881100; 58170152500; 58169251700; 57208922438; 57207112603; 58099353000; 55568524907 | daesung@knu.ac.kr; | CHEMOSPHERE | CHEMOSPHERE | 0045-6535 | 1879-1298 | 328 | SCIE | ENVIRONMENTAL SCIENCES | 2023 | 8.1 | 8.8 | 1.18 | 2025-06-25 | 10 | 12 | enriched PFOA-resistant microbes; Propionic acid production improved and; short carbon chain intermediates; Microbial electrosynthesis system; PFAS; PFOA; Biodegradation; Bioanode | DEGRADATION; METHANOSARCINA; REDUCTION; PHENOL | Bioanode; Biodegradation; Microbial electrosynthesis system; PFAS; PFOA | Biodegradation, Environmental; Caprylates; Fluorocarbons; Bioremediation; Microorganisms; Volatile fatty acids; carbon; perfluorooctanoic acid; propionic acid; fluorocarbon; octanoic acid derivative; perfluorooctanoic acid; Aquatic habitats; Bioanode; Degradation process; Drastic conditions; Enhanced biodegradation; High-energy costs; Microbial electrosynthesis system; Perfluorooctanoic acid; PFAS; Terrestrial habitat; biodegradation; biofilm; bioremediation; enrichment; microbial activity; organic compound; Article; biocatalysis; biodegradation; biofilm; bioremediation; controlled study; current density; electrosynthesis; Methanosarcina; microbial community; microflora; nonhuman; Petrimonas; metabolism; Biodegradation | English | 2023 | 2023-07 | 10.1016/j.chemosphere.2023.138584 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Fluorescent Lateral Flow Assay with Carbon Nanodot Conjugates for Carcinoembryonic Antigen | A lateral flow assay (LFA) sensor on a half-strip platform labeled with blue carbon nanodot-polystyrene (PS-CND) nanoconjugates was developed for the detection of carcinoembryonic antigen (CEA) levels in buffer and serum solutions from healthy and cancer patients. CNDs, biocompatible nanoparticles containing amino groups synthesized by hydrothermal synthesis, were conjugated to spherical polystyrene (PS) beads with an average diameter of 60 nm, followed by the attachment of a detection probe, anti-CEA (M0911042), using a heterobifunctional cross-linker. PS beads were used as a template in CND conjugates to provide uniform size and shape of fluorescent labels without losing CND fluorescence intensity after the antibody conjugation step and to improve fluorescence stability. Upon the interaction of CEA from samples with the anti-CEA (M0911042) probe-modified PS-CND, which was further adsorbed onto a test line composed of the capture anti-CEA (M0911041) physisorbed onto a nitrocellulose membrane, the fluorescent signals on the test line increased as a function of the CEA concentrations under irradiation with a portable 365 nm ultraviolet lamp. A linear concentration range of 0.04-70 nM in buffer was observed, with a limit of detection of 0.3 nM. The applicability of the developed LFA half-strip sensor for disease diagnosis was demonstrated by identifying fluorescent levels on the test line due to the presence of CEA in serum samples from cancer patients.

This tunability-stability dilemma makes it difficult to implement practical neuromorphic computing. A novel method is proposed to enhance the stability and controllability of conductive filaments by introducing imidazole groups that boost the nucleation of Cu nanoclusters in the ultrathin polymer switching layer through the initiated chemical vapor deposition (iCVD) process. It is confirmed that conductive filaments based on nanoclusters with specific gaps are generated in the copolymer medium using this method. Furthermore, by modulating the tunneling gaps, an ultra-wide conductance range of analog tunable conductive filaments is achieved from several hundreds of nS to a few mS with a sub-1 V driving voltage. Through this, both reliable and stable analog switching are achieved with low cycle-to-cycle and device-to-device weight update variations and separable state retention with 32 states. This approach paves the way for the extension of state availability in synaptic devices to overcome the tunability-stability dilemma, which is essential for the synaptic elements in neuromorphic systems. | Oh, Jungyeop; Yang, Sang Yoon; Kim, Sungkyu; Lee, Changhyeon; Cha, Jun-Hwe; Jang, Byung Chul; Im, Sung Gap; Choi, Sung-Yool | Korea Adv Inst Sci & Technol, Graphene 2D Mat Res Ctr, Sch Elect Engn, Daejeon 34141, South Korea; Sejong Univ, Dept Nanotechnol & Adv Mat Engn, Seoul 05006, South Korea; Korea Adv Inst Sci & Technol, Graphene 2D Mat Res Ctr, Dept Chem & Biomol Engn, Daejeon 34141, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | Choi, Sung-Yool/B-3383-2012; Jang, Byung Chul/GYV-0656-2022; Im, Sung/C-1823-2011; Kim, Sung Kyu/GSI-4036-2022 | 57205761271; 56469963900; 57221945294; 57207257308; 57194684802; 9238827900; 14420979700; 7408120246 | sungyool.choi@kaist.ac.kr; | MATERIALS HORIZONS | MATER HORIZ | 2051-6347 | 2051-6355 | 10 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 12.2 | 8.8 | 0.91 | 2025-06-25 | 9 | 8 | Binding energy; Chemical stability; Chemical vapor deposition; Cluster computing; Nucleation; Active metals; Artificial synapse; Conductance modulations; Conductive filaments; Imidazol; Imidazole group; Nanocluster nucleation; Neuromorphic computing; Novel methods; Tunabilities; Nanoclusters | English | 2023 | 2023-06-06 | 10.1039/d2mh01522f | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Improving the efficiency of metal ions doped Fe2O3 nanoparticles: Photocatalyst for removal of organic dye from aqueous media | The metal ion-based nanocomposite photocatalysts were accepted to exhibit a wide range of photocatalytic and biological applications. In this paper, we synthesize bare Fe2O3, 1 wt% metal (Ag, Co, and Cu) doped Fe2O3 nanoparticles (NPs) using a simple hydrothermal process and wet impregnation method. The as-prepared nanomaterials crystalline structure, shape, optical characteristics, and elemental composition were determined by using X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Scanning electron microscope (SEM), Energy-dispersive X-ray (EDS) and Transmission electron microscopy (TEM) techniques. Furthermore, the synthesized nanocomposites were utilized as a photosensitizer for the degradation of reactive red (RR120) and orange II (O-II) dyes under sunlight irradiation. The synthesized 1 wt% Ag–Fe2O3 (AgF) NPs samples exhibit a more exceptional catalytic performance of RR120 and O-II dyes (98.32%) within 120 min than the existing Fe2O3, 1 wt% Co–Fe2O3, and Cu–Fe2O3 NPs. The effect of parameters such as exciton formation under solar irradiation, charge recombination rate, and surface charge availability. The metal oxide-doped nanocomposite economic relevance is revealed by their long-term durability and recyclability in photodegradation reactions. The photocatalytic investigations show that the active species O2∙−, HO∙ and h+ play an important role in the dye degradation process. This research might pave the opportunity for the sustainable development of greater photocatalysts for photodegradation and a wide range of environmental applications. © 2023 | Huang-Mu, Lo; Devanesan, Sandhanasamy; Farhat, Karim; Kim, Woong; Sivarasan, Ganesan | Department of Environmental Engineering and Management, Chaoyang University of Technology, Taichung, 41349, Taiwan; Department of Physics and Astronomy, College of Science, King Saud University, P.
