| ○ | ○ | Article | Enhanced voltage and capacitance in flexible supercapacitors using electrospun nanofiber electrolytes and CuNi2O3@N-Doped omnichannel carbon electrodes | Developing functional solid polymer electrolytes (SPEs) is crucial for flexible, lightweight, and portable supercapacitors. This work presents an electrospinning approach to fabricate SPEs using poly(vinyl alcohol)-sodium chloride (PVA-NaCl) nanofibers (PNNF). CuNi2O3 nanoparticles deposited on nitrogen-doped omnichannel carbon nanofibers (CuNi2O3@N-OCCFs), coated onto a carbon cloth (CC), serve as the positive electrode, enhancing faradaic capacitance. Meanwhile, the rationally designed N-OCCFs, also coated onto CC, function as the negative electrode, providing a high-surface-area, and facilitating rapid electron transport. Comprehensive characterization revealed insights into the morphology and chemical composition of both electrodes and the PNNF electrolyte. An all-solid-state asymmetric flexible supercapacitor (AFSC) device, CuNi2O3@N-OCCFs-1.5//N-OCCFs-1.5, was assembled using PNNF as both the electrolyte and separator and evaluated against devices employing gel and aqueous electrolytes. The PNNF electrolyte enabled a wider potential window (2.2 V) compared to gel (2.0 V) and liquid (1.8 V) electrolytes. The AFSC achieved an impressive energy density of 63.6 Wh kg-1 at a power density of 1100 W kg-1, with 96.2% capacitance retention after 6000 charge/discharge cycles at 10 A g(-)1. When two devices were connected in series, they powered a red LED for 5.33 min and a blue LED for 1.43 min, demonstrating practical applicability. This study provides a simple and effective strategy for fabricating high-energy-density AFSCs with excellent cycling stability and broad potential for flexible electronics. | Kumar, Ponnaiah Sathish; Bae, Jihoon; Roh, Jong Wook; Min, Yuho; Lee, Sungwon | Daegu Gyeongbuk Inst Sci & Technol DGIST, Magnet Initiat Life Care Res Ctr, 333 Techno Jungang Daero, Daegu 711873, South Korea; Daegu Gyeongbuk Inst Sci & Technol DGIST, Dept Phys & Chem, 333 Techno Jungang Daero, Daegu 711873, South Korea; Kyungpook Natl Univ, Dept Nano & Adv Mat Sci & Engn, Daegu 37224, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Innovat Semicond Educ & Res Ctr Future Mobil, Daegu 41566, South Korea | Sathish Kumar, Ponnaiah/AAD-5806-2019 | 57212215943; 57211979978; 25638796100; 36782804100; 56976186600 | yuhomin@knu.ac.kr; swlee@dgist.ac.kr; | NANO CONVERGENCE | NANO CONVERG | 2196-5404 | 12 | 1 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2024 | 11 | 8.8 | N/A | 1 | 1 | Controllable preparation; Solid polymer electrolytes; Electrospinning; Omnichannel carbon fibers; Flexible supercapacitor | ELECTROCHEMICAL PERFORMANCE; NANOCOMPOSITE; NANOSHEETS | Controllable preparation; Electrospinning; Flexible supercapacitor; Omnichannel carbon fibers; Solid polymer electrolytes | English | 2025 | 2025-04-29 | 10.1186/s40580-025-00485-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Adsorption of dihydroxybenzene isomers over Schiff-based network-1-derived nitrogen-enriched carbon: Effective and favorable adsorption of hydroquinone | Urbanization and modernization through intense industrial activity led to the disposal of harmful and nonbiodegradable organic substances including dihydroxybenzene isomers such as hydroquinone, catechol, and resorcinol. A covalent-organic polymer Schiff-based network-1, SNW1 was synthesized, pyrolyzed, and subsequently carbonized again, after mixing with KOH, at 800 degrees C. The obtained carbon, prepared in two-stepcarbonization (named as SNW1-2DC), was applied to the adsorption of dihydroxybenzene isomers; showed remarkable performance in hydroquinone adsorption with the maximum adsorption capacity ( Q 0 ) of 1060 mg/g at neutral conditions. This Q 0 is 6.0 and 5.5 times that of activated carbon and the carbon obtained from the simple pyrolysis of SNW1, respectively; of note, this value represents the highest compared to any previously reported findings. Moreover, the regenerated adsorbent, with simple ethanol washing, performed well for up to 5 cycles. This material could be suggested as a promising adsorbent in hydroquinone removal from water. The adsorption mechanism, including hydrogen bonding, could be suggested. Interestingly, the performance of SNW1-2DC in the adsorptive removal of catechol and resorcinol was very low in comparison with that of hydroquinone. The relative adsorption performances of SNW1-2DC for dihydroxybenzene isomers could be explained with density functional theory calculation and thermodynamic parameters. The most favorable hydroquinone adsorption (among the three dihydroxybenzene isomers) over SNW1-2DC might be because of less endothermic adsorption and more effective H-boning interaction between hydroquinone and SNW1-2DC than that between catechol or resorcinol and the adsorbent. | Hossain, Md Abul; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Jhung, Sung/AAO-6683-2021 | 57936807700; 6701659467 | sung@knu.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 353 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 1.02 | 2025-05-07 | 2 | 2 | Adsorption; Carbonaceous materials; Dihydroxybenzene isomers; Hydroquinone; Schiff based network-1 | P-ARSANILIC ACID; PHENOLIC-COMPOUNDS; ACTIVATED CARBON; AQUEOUS-SOLUTION; REMOVAL; WATER; SULFAMETHOXAZOLE; LUMINESCENT; NITROPHENOL; DICLOFENAC | Adsorption; Carbonaceous materials; Dihydroxybenzene isomers; Hydroquinone; Schiff based network-1 | Activated carbon; Carbonization; Density functional theory; Hydrogen bonds; Isomers; Nitrogen; Organic polymers; Phenols; Potassium hydroxide; Biodegradable organics; Carbonaceous materials; Dihydroxybenzene isomers; Hydroquinone; Industrial activities; Nitrogen-enriched; Organic substances; Performance; Schiff based network-1; Simple++; Adsorption | English | 2025 | 2025-01-19 | 10.1016/j.seppur.2024.128540 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bridging domain spaces for unsupervised domain adaptation | Unsupervised Domain Adaptation (UDA) aims to transfer knowledge obtained from a labeled source domain to an unlabeled target domain, facing challenges due to domain shift-significant discrepancies in data distribution that impair model performance when applied to unseen domains. While recent approaches have achieved remarkable progress in mitigating these domain shifts, the focus remains on direct adaptation strategies from source to target domains. However, when the gap between the source and target domains is too substantial, directly aligning their distributions becomes increasingly difficult. Pseudo-labeling, a common strategy in direct adaptation, can further exacerbate this issue when the domain shift is severe. In such cases, incorrect pseudo-labels are likely to propagate through the adaptation process, leading to degraded performance and unstable training. Effective adaptation thus requires methods that can address these challenges by improving the reliability of pseudo-labels or reducing dependency on them. To address this challenge, we propose a novel approach that effectively alleviates domain shift by leveraging intermediate domains as bridges between the source and target domains. Specifically, we introduce a fixed ratio-based mixup to generate distinct intermediate domains between the source and target domains. By training on these augmented domains, we construct source-dominant and target-dominant models that possess distinct strengths and weaknesses, enabling us to implement effective complementary learning strategies. Furthermore, we enhance our fixed ratio-based mixup with uncertainty-aware learning, which addresses not only the image-level space but also the feature space, aiming to reduce the uncertainty at the most critical points within these spaces. Finally, we integrate confidence-based learning strategies, including bidirectional matching with high-confidence predictions and self-penalization with low-confidence predictions. Our extensive experiments on seven public benchmarks, including both single-source and multi-source scenarios, demonstrate the effectiveness of our method in UDA tasks. | Na, Jaemin; Jung, Heechul; Chang, Hyung Jin; Hwang, Wonjun | KT, Tech Innovat Grp, Seongnam, South Korea; Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu, South Korea; Univ Birmingham, Sch Comp Sci, Birmingham, England; Korea Univ, Sch Elect Engn, Seoul, South Korea | Hwang, Wonjun/AAD-9090-2021 | 57215652622; 55652175200; 35168664400; 7402323168 | jaemin.na@kt.com; heechul@knu.ac.kr; h.j.chang@bham.ac.uk; wjhwang@korea.ac.kr; | PATTERN RECOGNITION | PATTERN RECOGN | 0031-3203 | 1873-5142 | 164 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 7.6 | 8.9 | 0 | 2025-05-07 | 0 | 0 | Transfer learning; Domain adaptation; Uncertainty-aware learning | Domain adaptation; Transfer learning; Uncertainty-aware learning | Adversarial machine learning; Contrastive Learning; Federated learning; Bridging domains; Confidence predictions; Data distribution; Domain adaptation; Learning strategy; Modeling performance; Target domain; Transfer learning; Uncertainty; Uncertainty-aware learning; Domain Knowledge | English | 2025 | 2025-08 | 10.1016/j.patcog.2025.111537 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | CO2 capture using functionalized MIL-101(Cr) metal-organic frameworks: Functionality nanoarchitectonics of nanospace for CO2 adsorption | n this study, we investigated the effect of functional groups of metal-organic frameworks (MOFs) on CO2 adsorption at low pressure through experimental and computational approaches. We compared the performance of -SO3H, -NO2, aryl -NH2, and alkyl -NH2 groups (in similar molar quantities) in CO2 adsorption under the same conditions. The adsorption efficiency followed in the order: alkyl -NH2 > -SO3H>aryl -NH2 > -NO2 because of the different adsorption mechanisms over the groups. The main mechanism over alkyl -NH2 was the formation of ammonium carbamate via the carbamic acid formation. The adsorption mechanism over -SO3H and aryl -NH2 groups was Lewis acid-base and H-bonding interactions, while that over -NO2 group was solely Lewis acid-base interaction. The alkyl amine exhibited the best performance (in adsorption capacity, selectivity, and adsorption heat) due to its ability to form carbamate readily. On the contrary, aryl amine demonstrated lower performance than -SO3H groups, attributed to their low capability to form carbamate. These findings underscore the importance of amine type in CO2 adsorption, highlighting that aryl amines, different from alkyl amines, perform worse than other functional groups, such as -SO3H. | Lee, Gyudong; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Jhung, Sung/AAO-6683-2021 | 57200987600; 6701659467 | sung@knu.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 354 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 4.07 | 2025-05-07 | 3 | 4 | Alkyl amine; Aryl amine; CO2 capture; Functional group; Metal-organic frameworks | CARBON-DIOXIDE CAPTURE; ACID; SEPARATION; CHEMISTRY; SORPTION; SITES | Alkyl amine; Aryl amine; CO<sub>2</sub> capture; Functional group; Metal–organic frameworks | Metal-Organic Frameworks; Nanoclay; 2-group; Adsorption mechanism; Alkylamine; Aryl amines; CO2 capture; Functionalized; Functionals; Metalorganic frameworks (MOFs); NO 2; Performance; Hydrogen bonds | English | 2025 | 2025-02-19 | 10.1016/j.seppur.2024.129514 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Dual-cocatalyst-promoted photocatalytic treatment of persistent waterborne pollutants via in situ MXene-derived TiO2/Ti3C2 hybrids with plasmonic Ag nanoparticles | The integration of photocatalysts with MXenes and plasmonic metals has emerged as a promising strategy for enhancing wastewater treatment efficiency, leveraging the superior light-absorption and charge separation capabilities of these materials. In this study, we introduce an effective approach that significantly enhances the photocatalytic degradation of persistent organic pollutants by utilizing the synergistic benefits of dual cocatalysts: Ti3C2 (MXene) and Ag nanoparticles. We initially synthesized a series of TiO2/Ti3C2 hybrids by annealing Ti3C2 at various temperatures, aiming to optimize the size, distribution, and integration of TiO2 nanoparticles on a Ti3C2 substrate. These TiO2/Ti3C2 hybrids were then decorated with Ag nanoparticles to induce the surface plasmonic resonance effect, known to amplify photocatalytic efficiency. Notably, the optimized hybrid Ag/TiO2/Ti3C2 catalyst demonstrated significantly improved photocatalytic performance in degrading and mineralizing the persistent antibiotic sulfamethazine in water, outperforming TiO2/Ti3C2 hybrids, anatase TiO2, and other previously reported cutting-edge photocatalysts. This exceptional performance is primarily attributed to the synergistic effects of Ti3C2 and plasmonic Ag dual cocatalysts, which enhance optical absorption and specific surface area, as well as promote photoinduced charge transfer and separation. Additionally, the developed hybrids showed exceptional versatility in degrading various aqueous dye pollutants and maintained high efficacy across multiple cycles, underscoring their potential for recyclable and durable watertreatment applications. This work paves the way for the development of advanced MXene-based, plasmonically enhanced photocatalysts for the effective and sustainable treatment of waterborne pollutants. | Lee, Dong-Eun; Moru, Satyanarayana; Jo, Wan-Kuen; Tonda, Surendar | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; VIT AP Univ, Sch Adv Sci, Dept Phys, Amaravati 522237, AP, India | Jo, Wan/AAO-5329-2020; Tonda, Surendar/AAO-3358-2020; Moru, Satyanarayana/AAF-3189-2021; MORU, SATYANARAYANA/AAF-3189-2021 | 56605563300; 58562229700; 7103322277; 56114866900 | wkjo@knu.ac.kr; surendar.t86@gmail.com; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 352 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 9.16 | 2025-05-07 | 18 | 18 | MXenes; TiO2; Plasmonic effect; Photodegradation; Environmental remediation | DEGRADATION; LIGHT; TI3C2; TIO2; SULFAMETHAZINE; MECHANISM; OXIDATION; SOLAR | Environmental remediation; MXenes; Photodegradation; Plasmonic effect; TiO<sub>2</sub> | Charge transfer; Efficiency; Light absorption; Metal nanoparticles; Organic pollutants; Photocatalytic activity; Plasmonic nanoparticles; Plasmonics; Silver nanoparticles; Surface plasmons; Synthesis (chemical); TiO2 nanoparticles; Wastewater treatment; Water pollution; Charge-separation; Co catalysts; Environmental remediation; Mxenes; Photo degradation; Photocatalytic treatment; Plasmonic effects; Plasmonics; Wastewater treatment efficiencies; Waterborne pollutants; Titanium dioxide | English | 2025 | 2025-01-01 | 10.1016/j.seppur.2024.128261 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Fabrication of cellulose acetate membrane using deep eutectic solvent for water/isopropyl alcohol pervaporation | Deep eutectic solvents (DES) are eco-friendly alternatives to conventional organic solvents and have receive significant attention due to their low cost and biodegradable properties. These characteristics provide DES highly suitable for membrane applications. In this study, cellulose acetate (CA) membrane is fabricated using DES. The DES is prepared by mixing thymol (Thy) and decanoic acid (DA). CA is dissolved in the DES and the solution is casted into a film to fabricate non-porous membranes by phase inversion method. To find the optimum solvent for CA, various types of DES are tested with different compositions of which Thy and DA, both naturally occurring chemicals, are selected. Variations in membrane structure and performance are also analyzed by altering the ratio of Thy to DA. Additionally, it is confirmed that DES is completely removed during the phase inversion process after casting the CA dope solution, demonstrating that DES functions solely as a solvent and not as an additive. The fabricated non-porous CA membranes are applied for dehydration of a water and isopropyl alcohol mixture via pervaporation. The membranes exhibit a high flux of 5.381 kg/m2·h and a selectivity of 16. Both DES and CA are biodegradable and biocompatible, yielding viable substitutes for the toxic and harsh organic solvents traditionally used in membrane fabrication. © 2025 The Author(s) | Bae, Sun Ho; Lee, Geumbee; You, Jae Bem; Yoo, Youngmin | Green Carbon Research Center, Chemical Process Division, Korea Research Institute of Chemical Technology (KRICT), Daejeon, North Korea, School of Chemical Engineering and Applied Chemistry, Kyungpook National University (KNU), Daegu, North Korea; Department of Chemical Engineering, Kyungpook National University (KNU), Daegu, North Korea; Department of Chemical Engineering and Applied Chemistry, Chungnam National University (CNU), Daejeon, North Korea; Green Carbon Research Center, Chemical Process Division, Korea Research Institute of Chemical Technology (KRICT), Daejeon, North Korea | 58475271100; 56300598400; 55619455300; 55642500700 | jb.you@cnu.ac.kr; | Separation and Purification Technology | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 364 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 0 | 2025-05-07 | 2 | Cellulose acetate membrane; Deep eutectic solvent; Dehydration; Pervaporation | Cellulose Acetate; Dehydration; Inversion; Membranes; Propanols; Solvents; Water; Cellulose; Nafion membranes; Cellulose acetate membrane; Cellulose acetates; Decanoic acid; Deep eutectic solvents; Eco-friendly; Isopropyl alcohols; Low-costs; Organics; Porous membranes; Property; Dehydration | English | Final | 2025 | 10.1016/j.seppur.2025.132406 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Improved catalytic NO oxidation over Pt supported on sulfuric acid treated TiO2 | Promoting the formation of metallic Pt over the catalysts is the key to improving the NO reactivity. In general, TiO2 suppresses the oxidation of Pt by surface acidity and induces the formation of the metallic phase of Pt by PtTi interaction. However, the limited number of acidic sites (-OH) contributes to the formation of large Pt particles, which may lead to the formation of Pt2+ or Pt4+, resulting in performance degradation. In this study, we further formulated the acidic sites of the TiO2 with sulfuric acid treatment (SA-TiO2) to improve catalytic NO oxidation. During the SA treatment, the TiO2 surface is positively charged by the low pH, providing an environment for well-distributed sulfate. In the subsequent introduction of Pt, the increase in acidic sites for Pt adsorption greatly enhanced the dispersion of Pt. During this process, Pt formed bonds with sulfate as [Pt (NH3)4]-SO4. The surface species combined with SO4 and NH3 were decomposed during the calcination process, thereby inhibiting the oxidation of Pt, which promotes the formation of metallic Pt. As a result, highly reactive Pt0 and Pt2+ were further formulated by increasing the acidic sites of SA-TiO2, where the low-temperature NO oxidation performance was improved, regardless of the Pt loading (0.3 to 3 wt.%). | Bae, Wo Bin; Park, Jiseok; Go, You Jin; Byun, Sang Woo; Shin, Hyeonwoo; Kim, Young Jin; Jang, Jun Hee; Kang, Sung Bong | Rowan Univ, Dept Chem Engn, Glassboro, NJ 08028 USA; Gwangju Inst Sci & Technol, Sch Environm & Energy Engn, Gwangju 61005, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Gwangju Inst Sci & Technol, Res Ctr Innovat Energy & Carbon Optimized Synth Ch, Gwangju 61005, South Korea | Jang, Jun/AAK-6732-2021 | 57565868600; 57216936819; 59361659900; 57565279000; 57654657000; 59054565400; 59361495500; 37664400300 | sbkang@gist.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 357 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 1.02 | 2025-05-07 | 1 | 1 | Pt/TiO2; Sulfuric acid treatment; NO oxidation; Surface acidity; Dispersion and phase | PLATINUM OXIDE FORMATION; REDUCTION; PT/AL2O3; IMPACT; DISPERSION; PRECURSOR; STORAGE; CHARGE; OXYGEN; MODEL | Dispersion and phase; NO oxidation; Pt/TiO<sub>2</sub>; Sulfuric acid treatment; Surface acidity | Catalytic oxidation; Sulfur compounds; Titanium dioxide; Acidic sites; Dispersion and phase; Metallics; NH 3; NO oxidation; Pt/TiO 2; Sulfuric acid treatment; Sulphates; Surface acidity; TiO 2; Platinum compounds | English | 2025 | 2025-05-01 | 10.1016/j.seppur.2024.130033 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | MIL-101(Fe)-loaded mixed matrix membrane for H2O2 activation in fenton-like catalysis and enhanced degradation of ibuprofen | Ibuprofen (IBP), a widely used nonsteroidal anti-inflammatory drug, is frequently identified in aquatic ecosystems and may pose long-term environmental risks. In this study, using the phase inversion method, mixed matrix membranes (MMMs) were synthesized with polyvinylidene fluoride (PVDF), polyvinylpyrrolidone, and a metal-organic framework (MIL-101(Fe)) for the degradation of IBP in water. The synthesized PVDF/MIL-101(Fe) MMMs (denoted as PM-x, x = 2, 4, 6, and 8 wt.%) were employed as adsorbents and catalysts for hydrogen peroxide (H2O2) activation. Among the fabricated membranes, PM-8 exhibited a 96.2% IBP removal efficiency under optimized catalytic conditions, determined through systematic investigation of key parameters. Additionally, PM-8 maintained a high degradation efficiency (over 84.7%) across a broad pH range (3-11) and showed excellent reusability, retaining over 90.0% removal efficiency after five reuse cycles. The removal mechanism involved various adsorption interactions, including pi-pi electron donor-acceptor interactions, surface complexation, and hydrogen bonding, along with catalytic oxidation driven by reactive oxygen species (center dot OH, O2 center dot-, and 1O2), generated through Fe(II)/Fe(III) redox cycling. UPLC-MS/MS analysis identified major intermediate products formed via hydroxylation, decarboxylation, and dehydrogenation pathways, outlining a plausible degradation route that ultimately leads to the mineralization of IBP. This study presents a promising strategy for IBP removal from aquatic environments, contributing to advancements in wastewater treatment technologies. | Kwon, Da Kyung; Njaramba, Lewis Kamande; Cha, Byungjun; Kim, Minji; Kim, Hyeonjeong; Nam, Seong-Nam; Yoon, Yeomin; Park, Chang Min | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Army Acad Yeongcheon, Dept Chem & Environm Sci, 495 Hoguk Ro, Yeongcheon Si 38900, Gyeongsangbuk D, South Korea; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea | Park, Chang Min/CAA-8506-2022; Nam, Seong-Nam/ABT-9415-2022; Kamande, Lewis/JLL-5435-2023 | 59903479700; 57223183206; 57337280900; 59903586300; 58421791300; 57226757907; 7402126688; 57209588953 | dkda0606@knu.ac.kr; lewiskamande@knu.ac.kr; chabss72@knu.ac.kr; mji2881@knu.ac.kr; hjk23457@naver.com; namsn@kaay.ac.kr; yoony@ewha.ac.kr; cmpark@knu.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 373 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 0 | 2025-06-11 | 0 | 0 | Mixed matrix membrane; MIL-101(Fe); Ibuprofen; Fenton; Oxidation | OXIDATION | Fenton; Ibuprofen; MIL–101(Fe); Mixed matrix membrane; Oxidation | Plastic recycling; Reactive oxygen species; Redox reactions; Water recycling; Catalyse; Fenton; Fenton likes; Ibuprofen; MIL–101(fe); Mixed-matrix membranes; Non-steroidal anti-inflammatory drugs; Polyvinylidene fluorides; Removal efficiencies; Synthesised; Reusability | English | 2025 | 2025-11-18 | 10.1016/j.seppur.2025.133572 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Modulated electronic environment of Ru on CeO2 for superior NH3 decomposition catalysis | Ammonia has emerged as a promising, carbon-free carrier of hydrogen fuel, facilitating a sustainable energy transition. Ru-based catalysts have been widely employed to produce hydrogen via NH3 cracking catalysis, specifically for the Ru/CeO2 catalyst, which exhibits strong metal-support interactions between the active Ru metal and the ceria support. This study demonstrates the superior catalytic activity of Ru/CeO2 catalysts, supported by experimental evidence and theoretical validation. We focus more on how the metal-support interaction modulates the electronic state of Ru, thereby enhancing catalytic performance. Through systematic characterization of various supports, the electron transfer at the Ru-CeO2 interface enhances the electron density of Ru, thereby mechanistically influencing the initial NH3 activation and N-H dissociation. The theoretical calculation, performed using density functional theory, further confirms these observations: the electron back-donation effect of Ru, induced by the Ru-CeO2 interaction, lowers the ammonia activation barrier and increases the reaction rate. This work highlights the importance of an interfacial electronic state for designing superior ammonia decomposition catalysts. | Ju, Yanggeun; Byun, Sang Woo; Song, Yuna; Kim, Bogyung; Kang, Kyung Yeon; Kim, Hyeonbin; Kim, Young Jin; Kim, Minkyu; Kang, Sung Bong | Gwangju Inst Sci & Technol, Dept Environm & Energy Engn, Gwangju 61005, South Korea; Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, Gyeongbuk, South Korea; LG Chem, 188 Moonji Ro, Daejeon 34122, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Gwangju Inst Sci & Technol, Res Ctr Innovat Energy & Carbon Optimized Synth Ch, Gwangju 61005, South Korea | 57716869100; 57481416600; 59182252000; 57917365700; 59915550100; 59914670800; 59054565400; 57116750000; 59969495200 | mk_kim@ynu.ac.kr; sbkang@gist.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 374 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 0 | 2025-06-11 | 0 | 0 | Hydrogen production; Ru-Ce interaction; Ru-Ce interface; NH3 decomposition; Ru on CeO2 | AMMONIA DECOMPOSITION; HYDROGEN-PRODUCTION; MOLECULAR-DYNAMICS; PROMOTER; SUPPORT; ENERGY; NH3; NANOPARTICLES; ADSORPTION; CERIA | Hydrogen production; NH<sub>3</sub> decomposition; Ru on CeO<sub>2</sub>; Ru-Ce interaction; Ru-Ce interface | Activation energy; Decay (organic); Fluid catalytic cracking; Hydrogenolysis; Hydrolysis; Reaction rates; Carbon-free; Catalyse; CeO 2; Electronic environments; NH 3; NH3 decomposition; Ru on CeO2; Ru-ce interaction; Ru-ce interface; ]+ catalyst; Catalysis | English | 2025 | 2025-11-28 | 10.1016/j.seppur.2025.133723 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Overlooked interference of antibiotics on quorum sensing inhibitors for membrane biofouling mitigation by affecting AHLs and PQS pathway | Membrane biofouling, which severely limits the membrane technology application, can be mitigated by quorum sensing inhibitors (QSIs) that suppress quorum sensing (QS) and biofilm formation-related genes. However, antibiotics can potentially interfere QS pathway, thereby altering microbial community structure and biofilm formation. This study investigates the mechanism of antibiotics interference with QSIs of vanillin and methyl anthranilate on microbial gene expression along with bacterial community structure and metabolism in real surface water (SW) and secondary effluent (SE) systems during nanofiltration biofouling. We demonstrated that sulfamethoxazole (SMX) attenuated the quorum quenching (QQ) effect of vanillin by reducing its inhibitory impact on the expression of pseudomonas quinolone signal (PQS) biosynthesis genes (pqsA and pqsC), N-3-oxododecanoyl homoserine lactone (3OC12-HSL) and N-butyryl homoserine lactone (C4-HSL) receptor genes (lasR and rhlR), and rhamnolipids synthesis gene (rhlA) by over 44%. SMX weakened the QQ effect of methyl anthranilate by reducing its inhibition of PQS biosynthesis genes (pqsABCDE) and 3OC12-HSL synthesis gene (lasI) by 12-62%. The coexistence of antibiotics and QSIs led to an overexpression of antibiotic resistance genes (oprM and mexAB) up to 9 times compared to antibiotics alone. Additionally, SMX and tetracycline (TET) also reduced the inhibitory effect of QSIs on dominant genera with high metabolic and secretory performance (Acinetobacter and unclassifiedfEₙₜₑᵣₒbₐcₜₑᵣᵢₐcₑₐₑ) and carbohydrate/amino acid metabolism genes in SW and SE systems. These findings reveal that antibiotics can interfere with QS regulatory pathways and weaken the effect of QSIs, which provides new insights into applying QSIs for membrane biofouling control in the presence of antibiotics. | Xu, Huijie; Yang, Yu; Xia, Tian; Feng, Yuruo; Liu, Xinhui; Graham, Nigel J.

| ○ | ○ | Article | Pump-less forward osmosis and low-pressure membrane hybrid system for the removal of selected pharmaceuticals from water | The number of pharmaceutically active compounds (PhACs) has increased with the development of the pharmaceutical industry and is continuously detected in aquatic environments. This study demonstrates a pump-less forward osmosis low-pressure membrane (FO-LPM) hybrid system for the effective removal of selected PhACs (i. e., propranolol (PRP), naproxen (NPX), and antipyrine (AP)), enabling sustainable and safe wastewater reuse. The optimal operating condition of the FO-LPM hybrid system was identified as a draw solution of 1 M NaCl and a nanofiltration membrane, providing an excellent balance between water flux and reverse salt flux. Under optimized conditions, maximum retentions of 98.8 %, 97.7 %, and 95.5 % for PRP, NPX, and AP were achieved, respectively. Additionally, different water chemistry parameters (solution pH, natural organic matter (NOM), and divalent cations (Ca2+)) were evaluated to understand the governing factors influencing PhAC retention in the FO-LPM hybrid system. In' the presence of NOM and divalent ions, the retention of PhACs by the FO-LPM hybrid system remained at 99.8 %. These results suggest that the primary governing factor for the retention of the selected PhACs by the FO-LPM hybrid system is size exclusion. | Han, Seungyeon; Jung, Bongyeon; Park, Chanhyuk; Jang, Min; Park, Chang Min; Nam, Seong-Nam; Yoon, Yeomin | Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae gil, Seoul 03760, South Korea; Kwangwoon Univ, Dept Environm Engn, 447-1 Wolgye dong Nowon gu, Seoul, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Army Acad Yeongcheon, Dept Chem & Environm Sci, 495 Hoguk ro, Yeongcheon Si 38900, Gyeongsangbuk D, South Korea | Nam, Seong-Nam/ABT-9415-2022 | 59160736400; 57211690823; 59893314800; 36762550700; 57209588953; 57226757907; 7402126688 | namsn76@gmail.com; yoony@ewha.ac.kr; | SEPARATION AND PURIFICATION TECHNOLOGY | SEP PURIF TECHNOL | 1383-5866 | 1873-3794 | 372 | SCIE | ENGINEERING, CHEMICAL | 2024 | 9 | 8.9 | 0 | 2025-06-11 | 0 | 0 | Forward osmosis; Low-pressure membrane; Hybrid system; Pharmaceutically active compounds; Micropollutants; Wastewater treatment | PERSONAL CARE PRODUCTS; DRINKING-WATER; HUMIC-ACID; NANOFILTRATION; REJECTION; ULTRAFILTRATION; SULFAMETHOXAZOLE; PERFORMANCE; NF | Forward osmosis; Hybrid system; Low-pressure membrane; Micropollutants; Pharmaceutically active compounds; Wastewater treatment | Aquatic environments; Effective removals; Forward osmosis; Low pressure membranes; Micropollutants; Naproxens; Natural organic matters; Pharmaceutical industry; Pharmaceutically active compounds; Wastewater reuse; Osmosis membranes | English | 2025 | 2025-11-01 | 10.1016/j.seppur.2025.133499 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Recursive reservoir concatenation for salt-and-pepper denoising | We propose a recursive reservoir concatenation architecture in reservoir computing for salt-and-pepper noise removal. The recursive algorithm consists of two components. One is the initial network training for the recursion. Since the standard reservoir computing does not appreciate images as input data, we designed a nonlinear image-specific forward operator that can extract image features from noisy input images, which are to be mapped into a reservoir for training. The other is the recursive reservoir concatenation to further improve the reconstruction quality. Training errors decrease as more reservoirs are concatenated due to the hierarchical structure of the recursive reservoir concatenation. The proposed method outperformed most analytic or machine-learning based denoising models for salt-and-pepper noise with a training cost much lower than other neural network-based models. Reconstruction is completely parallel, in that noise indifferent pixels can be removed in parallel. | Lee, In-mo; Kim, Yoojeung; Kim, Taehoon; Choi, Hayoung; Yang, Seung Yeop; Kim, Yunho | Ulsan Natl Inst Sci & Technol, Dept Math Sci, Ulsan, South Korea; Kyungpook Natl Univ, Dept Math, Daegu, South Korea | Kim, Yunho/ITV-5368-2023; Choi, Hayoung/U-7046-2019; Kim, Yunho/F-4765-2014 | 59418094800; 59417838700; 59417838800; 56942685000; 56589212300; 55699527100 | dlsah51@unist.ac.kr; taehoon.kim@unist.ac.kr; hayoung.choi@knu.ac.kr; seungyeop.yang@knu.ac.kr; yunhokim@unist.ac.kr; | PATTERN RECOGNITION | PATTERN RECOGN | 0031-3203 | 1873-5142 | 160 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 7.6 | 8.9 | 0 | 2025-05-07 | 0 | 0 | Reservoir computing; Image restoration; Small data | ECHO STATE NETWORKS; DEEP CNN; IMAGE; BACKPROPAGATION; REMOVAL | Image restoration; Reservoir computing; Salt-and-pepper noise; Small data | De-noising; Network training; Recursions; Recursive algorithms; Reservoir Computing; Salt and peppers; Salt-and-pepper noise; Salt-and-pepper noise removal; Small data; Two-component | English | 2025 | 2025-04 | 10.1016/j.patcog.2024.111196 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Sex-Specific Obesity Paradox in Critically Ill Patients With Severe Acute Kidney Injury: A Retrospective Analysis | OBJECTIVES:Although obesity is typically correlated with adverse outcomes in various diseases, certain acute critical illnesses exhibit a phenomenon known as the obesity paradox. This study evaluated sex-specific differences in the prognostic implications of the body mass index (BMI) of patients with severe acute kidney injury (AKI) requiring continuous renal replacement therapy (CRRT).DESIGN:A multicenter retrospective cohort study.SETTING:Data from eight tertiary hospitals in Korea.PATIENTS:A total of 3805 critically ill patients receiving CRRT. Patients were categorized into four BMI groups: underweight, normal weight, overweight, and obese.INTERVENTIONS:None.MEASUREMENTS AND MAIN RESULTS:There were 2308 male and 1497 female patients. The 90-day mortality risk significantly differed among BMI groups in the overall patient population and the male subpopulation but not the female subpopulation. Following adjustment for confounding variables, the 90-day mortality risk was higher in the underweight group than in the obese group (hazard ratio [HR], 1.20; 95% CI, 1.05-1.36; p = 0.006). Among male patients, the 90-day mortality risk was higher in both the underweight and normal weight groups than in the obese group (underweight: HR, 1.30; 95% CI, 1.10-1.53; p = 0.002 and normal weight: HR, 1.18; 95% CI, 1.04-1.35; p = 0.010); however, no such association was observed among female patients. Subgroup analysis demonstrated the obesity paradox in male patients of old age, with septic AKI, or with low albumin levels.CONCLUSIONS:There were sex differences in the association between BMI and mortality in critically ill patients with severe AKI. Although the precise distribution of fat mass and muscle mass was not identified, obese male patients had a more favorable prognosis, which was not evident among female patients. These findings highlight the importance of considering sex-specific factors in understanding the complex relationship between obesity and mortality in critically ill patients with AKI. | Jung, Hyo Jin; Seo, Yu Jin; Jung, Jiyun; Lee, Jangwook; Park, Jae Yoon; Kim, Yong Chul; Lee, Sung Woo; Ban, Tae Hyun; Park, Woo Yeong; Kim, Kipyo; Kim, Hyosang; Kim, Kyeongmin; Jung, Hee-Yeon; Choi, Ji-Young; Cho, Jang-Hee; Park, Sun-Hee; Kim, Chan-Duck; Lim, Jeong-Hoon; Kim, Yong-Lim | Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Nephrol, Daegu 41944, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu 41566, South Korea; Dongguk Univ, Data Management & Stat Inst, Ilsan Hosp, Goyang, South Korea; Dongguk Univ, Res Ctr Chron Dis & Environm Med, Coll Med, Gyeongju, South Korea; Dongguk Univ, Ilsan Hosp, Dept Internal Med, Goyang 410773, South Korea; Dongguk Univ, Coll Med, Dept Internal Med, Gyeongju, South Korea; Seoul Natl Univ Hosp, Dept Internal Med, Seoul 03080, South Korea; Uijeongbu Eulji Univ, Med Ctr, Dept Internal Med, Uijongbu, Gyeonggi Do, South Korea; Catholic Univ Korea, Eunpyeong St Marys Hosp, Coll Med, Dept Internal Med, Seoul, South Korea; Keimyung Univ, Dongsan Hosp, Sch Med, Dept Internal Med, Daegu, South Korea; Inha Univ, Sch Med, Dept Internal Med, Incheon, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Div Nephrol,Dept Internal Med, Seoul, South Korea; Eulji Univ, Daejeon Eulji Univ Hosp, Coll Med, Dept Internal Med, Daejeon, South Korea | Lim, Jeong-Hoon/ABE-6003-2020; Cho, Jang-hee/ABD-3534-2020; Jung, Hee-Yeon/AFB-8578-2022; Kim, Yong-Lim/AGK-3172-2022; Park, Sun-Hee/LMN-0033-2024 | 59657511100; 59167627900; 57211813518; 57223232128; 56603383500; 59725715200; 56708181900; 56119751700; 36344980100; 57164118000; 57190118848; 57199438486; 57196396467; 7501393222; 7403536291; 7501831741; 8558530700; 55360244300; 55633533600 | hy-jung@knu.ac.kr; jyss1002@hanmail.net; jh-cho@knu.ac.kr; sh-park@knu.ac.kr; jh-lim@knu.ac.kr; ylkim@knu.ac.kr; | CRITICAL CARE MEDICINE | CRIT CARE MED | 0090-3493 | 1530-0293 | 53 | 2 | SCIE | CRITICAL CARE MEDICINE | 2024 | 6 | 8.9 | 0 | 2025-05-07 | 0 | 0 | acute kidney injury; body mass index; continuous renal replacement therapy; critical illness; intensive care unit; mortality; obesity paradox; sex difference | CLINICAL-PRACTICE GUIDELINES; KOREAN SOCIETY; MORTALITY; SEPSIS; DISEASE; COHORT | acute kidney injury; body mass index; continuous renal replacement therapy; critical illness; intensive care unit; mortality; obesity paradox; sex difference | Acute Kidney Injury; Aged; Body Mass Index; Continuous Renal Replacement Therapy; Critical Illness; Female; Humans; Male; Middle Aged; Obesity; Obesity Paradox; Prognosis; Republic of Korea; Retrospective Studies; Severity of Illness Index; Sex Factors; Thinness; albumin; C reactive protein; calcium; creatinine; hemoglobin; phosphate; potassium; acute kidney failure; adult; aged; albumin blood level; albumin level; Article; body composition; body mass; body surface; calcium blood level; Charlson Comorbidity Index; cohort analysis; comorbidity; continuous renal replacement therapy; controlled study; creatinine blood level; critical illness; critically ill patient; disease severity; fat mass; female; hemoglobin blood level; hospitalization; human; hypertension; in-hospital mortality; intensive care unit; invasive ventilation; Korea; major clinical study; male; mortality rate; mortality risk; muscle mass; nutritional status; obesity; obesity paradox; phosphate blood level; potassium blood level; potential difference; prevalence; prognosis; retrospective study; sepsis; Sequential Organ Failure Assessment Score; sex difference; survival rate; tertiary care center; underweight; body mass; clinical trial; complication; critical illness; epidemiology; middle aged; mortality; multicenter study; obesity; obesity paradox; severity of illness index; sex factor; South Korea | English | 2025 | 2025-02 | 10.1097/ccm.0000000000006538 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Antibacterial and bioadhesive characteristics of mussel-inspired hyaluronic acid hydrogels encapsulated with sea urchin-shaped copper-coated silicon dioxide nanoparticles | The urgent need to mitigate the deadly effects of infectious diseases underscores the significance of incorporating antibacterial properties into wound-healing treatments. Hydrogel systems have gained substantial attention as wound-dressing patches owing to their superior fluid absorption, versatility in chemical and physical properties, capacity for biomolecule entrapment, and excellent biocompatibility. Many research efforts have focused on embedding antibacterial agents into hydrogel networks to develop effective and reliable wound-dressing solutions. Therefore, this study aims to investigate antibacterial and bioadhesive hydrogels crafted by embedding sea urchin-shaped copper-coated silicon dioxide nanoparticles (Cu@SiO2) into catechol-modified and photopolymerizable hyaluronic acid (HA) hydrogels. Inspired by marine mussels, whose foot proteins enable strong adhesion to various surfaces, we chemically modified materials with catechol groups to introduce bioadhesive properties. This modification was characterized using Nuclear Magnetic Resonance (NMR), Fourier-Transform Infrared (FT-IR), and Powder X-ray Diffraction (PXRD) spectroscopy. The bioadhesive strength of the modified surfaces was validated through lap-shear testing. Incorporating Cu@SiO2 into the catechol-modified HA-based hydrogel enhanced their antibacterial activity and mechanical integrity. The bactericidal efficacy of the hydrogel was tested against three distinct bacterial strains, while its biocompatibility was evaluated using mouse embryonic fibroblasts (MEFs). These outstanding properties position the Cu@SiO2-hydrogel as a strong candidate for use in wound-dressing patches and other biomedical applications. | Hong, Hye Jin; Gwon, Kihak; Park, Gisang; Yu, Jeong-Hoon; Lee, Seonhwa; Yu, Jong-Sung; Lee, Do Nam | Dankook Univ, Inst Tissue Regenerat Engn ITREN, Cheoanan 31116, South Korea; Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Daegu Gyeongbuk Inst Sci & Technol DGIST, Dept Energy Sci & Engn, Daegu 42988, South Korea; Mayo Clin, Dept Physiol & Biomed Engn, Rochester, MN 55904 USA; Kwangwoon Univ, Ingenium Coll Liberal Arts Chem, Seoul 01897, South Korea | Gwon, Kihak/AAE-2737-2022 | 55549261900; 50461594700; 56497444700; 57220154079; 57216716294; 7405524802; 8556814000 | jsyu@dgist.ac.kr; donamlee@hanmail.net; | CARBOHYDRATE POLYMER TECHNOLOGIES AND APPLICATIONS | CARBOHYDR POLYM TECH | 2666-8939 | 10 | ESCI | CHEMISTRY, APPLIED;POLYMER SCIENCE | 2024 | 6.5 | 9.0 | 0 | 2025-05-07 | 0 | 0 | Adhesive hydrogel; Catechol hyaluronic acid; Copper-coated nanoparticles; Antibacterial agent; Wound healing | DRUG-DELIVERY SYSTEM; RELEASE; ADHESIVE; CATECHOL; CHITOSAN; GROWTH | Adhesive hydrogel; Antibacterial agent; Catechol hyaluronic acid; Copper-coated nanoparticles; Wound healing | English | 2025 | 2025-06 | 10.1016/j.carpta.2025.100781 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
