○ Article ⓘ New Result On Mismatched Double Fuzzy Summation Inequality ⓘ This paper proposes a new result on mismatched double fuzzy summation inequality. The mismatched double fuzzy summation inequality usually originates from the control system design with using the Takagi-Sugeno fuzzy model, in which the controller and the system are with mismatched membership functions. Compared with the existing method to deal with the mismatched double fuzzy summation inequality, the proposed one is less conservative and does not introduce additional decision variables. Three examples including the mismatched membership functions of the Takagi-Sugeno fuzzy control system in the discrete-time case, the continuous-time case and the interval type-2 fuzzy system under state feedback control mechanism are used to show that the new result is less conservative than the existing one. © 1993-2012 IEEE. ⓘ Li, Feng; Ni, Zhenghao; Lee, Sangmoon; Shen, Hao ⓘ Anhui University of Technology, School of Electrical and Information Engineering, Ma'anshan, 243032, China, Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, 41566, South Korea; Anhui University of Technology, School of Electrical and Information Engineering, Ma'anshan, 243032, China; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, 41566, South Korea; Anhui University of Technology, School of Electrical and Information Engineering, Ma'anshan, 243032, China ⓘ ⓘ 56589219600; 58614617100; 59510733500; 35230989600 ⓘ moony@knu.ac.kr; ⓘ IEEE Transactions on Fuzzy Systems ⓘ IEEE T FUZZY SYST ⓘ 1063-6706 1941-0034 SCIE COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ENGINEERING, ELECTRICAL & ELECTRONIC ⓘ 2024 11.9 2.9 0 2025-05-07 ⓘ 0 ⓘ ⓘ Imperfect premise matching; mismatched double fuzzy summation inequality takagi-sugeno fuzzy systems; mismatched membership function ⓘ Adaptive control systems; Continuous time systems; Discrete time control systems; Feedback control; Fuzzy control; Fuzzy systems; State feedback; Control system designs; Decision variables; Imperfect premise matching; Matchings; Memberships function; Mismatched double fuzzy summation inequality takagi-sugeno fuzzy system; Mismatched membership function; New results; Takagi Sugeno fuzzy models; Takagi Sugeno fuzzy systems; Membership functions ⓘ English Article in press 2025 10.1109/tfuzz.2025.3554757 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Secure Control for T-S Fuzzy Wind Turbine Systems Under Hybrid Cyberattacks via an Adaptive Memory Event-Triggered Mechanism ⓘ This article addresses the secure control problem for the Takagi-Sugeno (T-S) fuzzy wind turbine system (WTS) subject to hybrid cyberattacks. To reduce system performance loss and redundant data transmission under such attacks, a novel adaptive memory event-triggered mechanism (ETM) is proposed, offering two key advantages. First, unlike traditional ETMs that rely solely on current system information, the adaptive memory ETM utilizes historical release data to adjust communication frequency and enhance control effectiveness. Second, an attack-related triggering condition and adaptive law are introduced to reduce the abnormaldata transmission induced by denial of service (DoS) attacks and extend the lifespan of the sensor node. Sufficient conditions are derived to ensure the mean-square H-infinity asymptotic stability of the resulting T-S fuzzy WTS, while also guaranteeing uniformly ultimate boundedness in the presence of DoS attacks. Finally, an illustrative example is used to show the effectiveness of the proposed method. ⓘ Xu, Dong; Liu, Yajuan; Lee, Sangmoon ⓘ North China Elect Power Univ, Sch Control & Comp Engn, Beijing 102206, Peoples R China; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea ⓘ Lee, Sangmoon/C-4502-2018; Yajuan, Liu/JZD-8537-2024 ⓘ 57226859976; 55255775300; 59510733500 ⓘ dxu1997@126.com; yajuan.liu.12@gmail.com; moony@knu.ac.kr; ⓘ IEEE TRANSACTIONS ON FUZZY SYSTEMS ⓘ IEEE T FUZZY SYST ⓘ 1063-6706 1941-0034 33 5 SCIE COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;ENGINEERING, ELECTRICAL & ELECTRONIC ⓘ 2024 11.9 2.9 0 2025-05-07 ⓘ 0 1 Adaptive memory event-triggered mechanism (AMETM); hybrid cyberattacks; secure control; wind turbine system (WTS) ⓘ MULTIAGENT SYSTEMS ⓘ Adaptive memory event-triggered mechanism; hybrid cyberattacks; secure control; wind turbine system ⓘ Data communication systems; Digital communication systems; Network security; Wind turbines; Adaptive memory; Adaptive memory event-triggered mechanism; Condition; Cyber-attacks; Data-transmission; Event-triggered; Hybrid cyberattack; Secure control; Takagi-sugeno; Wind turbine systems; Sensor nodes ⓘ English 2025 2025-05 10.1109/tfuzz.2025.3525778 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Active metal cation exchanged in ZSM-5 for enhanced direct air capture of CO2 ⓘ Zeolites have proved their potential as cost-effective adsorbents for CO2 capture; further development is worth optimizing their performance for large-scale direct air capture (DAC) applications. In this study, ZSM-5 zeolites were prepared and exchanged with alkali cations (Na and K) and alkaline earth cations (Mg, Ca and Ba) to investigate their performances for the CO2 capture from atmospheric air in the DAC system. We found that the cation charge density is critical to determining the DAC capacity of ZSM-5 zeolites. In detail, ZSM-5 with a low cation charge density (e.g., K+ with a charge density of 0.39) struggles to effectively capture CO2 at low concentrations since CO2 adsorption relies on electrostatic interactions with quadrupole CO2 by cation charge density. Conversely, an excessively high cation charge density has a detrimental effect as adsorption sites become shielded by H2O and CO2 on cations (e.g., Ca2+ and Mg2+ with charge densities of 2.06 and 7.28, respectively), reducing the accessible CO2 capacity. Consequently, Ba-ZSM-5, featuring Ba2+ with a moderate charge cation density of 0.81, exhibits the highest DAC capacity (500 ppm CO2 in the air at RH 13%, 0.4 mmol g-1), with fast kinetics and stable reproducibility, appealing that appropriate cation charge density is critical to imparting the high DAC capacity of ZSM-5 zeolites. In addition, DRIFTS results confirmed the moisture swing adsorption behavior, in which the adsorbed CO2 is desorbed directly by water over Ba-ZSM-5. These results provide valuable insights for the design of zeolites-based DAC systems. ⓘ Kim, Do Yeong; Ryu, Kyeong-Hun; Bin Bae, Wo; Min, Haehyun; Kweon, Sungjoon; Park, Min Bum; Kang, Dohyung; Kim, Young Jin; Kang, Sung Bong ⓘ Gwangju Inst Sci & Technol, Sch Environm & Energy Engn, Gwangju 61005, South Korea; Rowan Univ, Dept Chem Engn, Glassboro, NJ 08028 USA; SUNY Syracuse, Coll Environm Sci & Forestry, Dept Chem Engn, Syracuse, NY 13210 USA; Incheon Natl Univ, Dept Energy & Chem Engn, Incheon 22012, South Korea; Seoul Natl Univ Sci & Technol, Dept Future Energy Convergence, 232 Gongreung Ro, Seoul 01811, 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 ⓘ ⓘ 57481464200; 59424163300; 57218296461; 57367334300; 57201686056; 34873080400; 59461565400; 59054565400; 59969495200 ⓘ sbkang@gist.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 503 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 2.45 2025-05-07 ⓘ 4 4 Direct air capture; ZSM-5; Alkali metal; Alkaline earth metal; Cation charge density ⓘ CARBON-DIOXIDE; ION-EXCHANGE; ADSORPTION; ZEOLITES; ALKALI; TEMPERATURE; SIMULATION; DEPOSITION; FAUJASITE; SORPTION ⓘ Alkali metal; Alkaline earth metal; Cation charge density; Direct air capture; ZSM-5 ⓘ Alkali metals; Alkaline earth metals; Alkalinity; Barium compounds; Carbon capture; Carbon capture and utilization; Cost effectiveness; Active metals; Air captures; Alkaline-earth metals; Capture system; Cation charge; Cation charge density; Metal cation; Performance; ZSM-5; ZSM-5 zeolites; Direct air capture ⓘ English 2025 2025-01-01 10.1016/j.cej.2024.158380 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Adsorptive removal of nitrogen-containing compounds from liquid fuel using a Zr-based metal-organic framework composed of amine or ammonium sites: Synergistic contribution of the loaded sites and defects ⓘ Removal of nitrogen-containing compounds (NCCs) is important to effectively utilize fuel, especially microalgaederived ones with high N contents. In this work, adsorptive removal of NCCs like quinoline (QUI) and indole (IND) from liquid fuel was carried out by using various metal-organic frameworks (MOF-808s) such as pristine MOF-808, aminated MOF-808s with defect, an aminated MOF-808, defective MOF-808s, and a defective MOF808 with ammonium sites. The performance of the MOF-808 increased with increasing the content of both the -NH2 group and defects; showing a very favorable or synergistic contribution of the two sites to the adsorption. Moreover, the protonation of the aminated MOF-808s with defect increased further QUI adsorption although this treatment decreased the IND adsorption. Calculations were applied to understand the adsorption over amino or ammonium sites; hydrogen bonding had a dominant role in the adsorption of QUI and IND over the aminated MOF-808s; whereas, acid-base interactions were important in the QUI adsorption over MOF-808 with ammonium sites. One adsorbent, P-M808-50(NH2/D) (a protonated MOF-808 composed of ample -NH2 groups and defects), with a very remarkable maximum capacity for QUI (769 mg/g, the second one, after UiO-66 (Zr)-DHTZ) could be suggested as a potential adsorbent to remove NCCs (especially basic ones) from fuel, based on the huge adsorption capacity and ready recyclability via simple solvent treatment. ⓘ Lee, So Yeon; 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 ⓘ 59725495900; 57200987600; 6701659467 ⓘ sung@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 512 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 0 2025-05-07 ⓘ 0 0 Adsorption; Amine/ammonium site; Denitrogenation; Defect; Metal-organic framework; MOF-808 ⓘ MODEL FUEL; REMARKABLE ADSORBENT; SELECTIVE REMOVAL; DENITROGENATION; INDOLE; DESULFURIZATION; QUINOLINE; CAPACITY; OIL; CARBONS ⓘ Adsorption; Amine/ammonium site; Defect; Denitrogenation; Metal–organic framework; MOF-808 ⓘ Antiknock compounds; Metal-Organic Frameworks; Zirconium; Zirconium compounds; 2-group; Adsorptive removal; Amine/ammonium site; Denitrogenation; Metalorganic frameworks (MOFs); Micro-algae; Microalga; MOF-808; N content; Performance; Protonation ⓘ English 2025 2025-05-15 10.1016/j.cej.2025.162300 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Advanced nanoarchitectural superstructure hybridized with covalent organic nanosheets and 2H-MoS2 to boost the performance of sodium-ion batteries ⓘ Push–pull structured covalent organic nanosheets (CONs) are promising anode materials for sodium-ion batteries (SIBs) owing to their flexible π-conjugated frameworks and tunable porosity. In contrast, MoS2 anodes have a high capacity but suffer from capacity degradation owing to their low intrinsic conductivity and volume expansion. To address these limitations, we developed a composite of 2H-MoS2 nanosheets and multi-layered hollow CON spheres (CON/MoS2-HS). This composite was fabricated via the solvothermal synthesis of 2H-MoS2 using CONs stacked on polystyrene beads as a template. CON/MoS2-HS exhibited improved electrical and ionic conductivities and reversible capacity, while its robust structural integration limited the changes in volume and mechanical stress during cycling, resulting in excellent long-term cycling stability. In contrast, reduced graphene oxide (rGO)/MoS2-HS was characterized by weaker interactions between rGO and 2H-MoS2, meaning that MoS2 aggregation and volume expansion could not be prevented, thus compromising cycle stability and capacity. The CON/MoS2-HS electrode delivered a high reversible capacity of 671.8 mAh g−1 (∼97% of the theoretical capacity) after 600 cycles at 100 mA g−1 and retained a capacity of 203.1 mAh g−1 after 5000 cycles at 5000 mA g−1. The rate performance and long-term cycling stability of the CON/MoS2-HS electrode outperformed those of conventional MoS2-based anodes, demonstrating the strong synergistic relationship between the multilayered CON architecture and 2H-MoS2 nanosheets. © 2025 The Authors ⓘ Lee, Minseop; Kim, Ji-Min; Lee, Nakyeong; Park, Jin Kuen; Paek, Seung-Min ⓘ Department of Chemistry, Kyungpook National University, Daegu, 41566, South Korea; Department of Chemistry, Kyungpook National University, Daegu, 41566, South Korea; Department of Chemistry, Hankuk University of Foreign Studies, Gyeonggi-do, Yongin, 17035, South Korea; Department of Chemistry, Hankuk University of Foreign Studies, Gyeonggi-do, Yongin, 17035, South Korea; Department of Chemistry, Kyungpook National University, Daegu, 41566, South Korea ⓘ ⓘ 57201550392; 59962313300; 59091010500; 55085701500; 7102686289 ⓘ jinkpark@hufs.ac.kr; ⓘ Chemical Engineering Journal ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 519 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 ⓘ 0 ⓘ ⓘ Anode; Covalent organic nanosheet; Heterostructure; MoS<sub>2</sub>; Sodium-ion battery ⓘ Anode materials; Cobalt compounds; Expansion; Heterojunctions; Layered semiconductors; Metal ions; Molybdenum compounds; Nanosheets; Sulfur compounds; Covalent organic nanosheet; Cycling stability; MoS 2; Multi-layered; Organics; Performance; Push pull; Reduced graphene oxides; Sodium ion batteries; Volume expansion; Anodes ⓘ English Final 2025 10.1016/j.cej.2025.164931 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Angiogenic sticky porous microgels as injectable stem cell carriers for site-directed treatment of osteoporosis ⓘ Injectable stem cell therapy has emerged as a promising approach for treating various bone diseases from bony defects to osteoporosis. While microgels serve as preformed scaffolds for cell transplantation with minimal surgical intervention, off-target administration and poor vascularization limit their clinical translation, especially for treating vascularized tissues. Here, we propose sticky porous microgels with bioengineered angiogenic mussel adhesive protein (MAP-VEGF) as injectable cell carriers to accomplish site-directed delivery of stem cells with augmented vascularization. A suit of highly homogeneous porous microgels (MVPs) microfluidically fabricated using the oxidation-induced covalent crosslinking of MAP-VEGF showed a superior adhesion ability and appropriate physical properties, enabling the maintenance of the viability and stemness of loaded mesenchymal stem cells (MSCs) after syringe injection and supporting differentiation toward the desired lineages upon inductive culture. Injection of the MSC-laden MVPs induced the ectopic formation of vascularized bone constructs in target sites of the subcutaneous layer and accelerated bone regeneration in cranial bone defects and osteoporotic cancellous bone spaces in vivo. Thus, the developed MVPs hold great potential for the in situ construction of vascularized tissues via a minimally invasive administration procedure with further expansion to stem cell-mediated regenerative therapies for various intractable diseases in humans. ⓘ Jo, Yun Kee; Min, Kyoung-Ik; Baek, Myeong Jae; Kim, Dong-Pyo; Cha, Hyung Joon ⓘ Kyungpook Natl Univ, Adv Inst Sci & Technol, Dept Biomed Convergence Sci & Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Adv Bioconvergence, Daegu 41566, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu 41944, South Korea; Pohang Univ Sci & Technol, Dept Chem Engn, Pohang 37673, South Korea; Pohang Univ Sci & Technol, Sch Convergence Sci & Technol, Med Sci & Engn, Pohang 37673, South Korea ⓘ Joon, Hyung/AAO-8422-2020 ⓘ 56123757800; 25028141900; 59790792700; 56109750200; 55954303800 ⓘ dpkim@postech.ac.kr; hjcha@postech.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 515 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 N/A ⓘ 0 0 Injectable cell carriers; Sticky porous microgels; Mussel adhesive protein; Stem cell therapy; Vascularized bone constructs ⓘ BONE-FORMATION; PROTEIN; VEGF; SCAFFOLDS; DELIVERY; DESIGN ⓘ Injectable cell carriers; Mussel adhesive protein; Stem cell therapy; Sticky porous microgels; Vascularized bone constructs ⓘ Cell adhesion; Crosslinking; Fiber bonding; Metabolic engineering; Tissue culture; Tissue regeneration; Transplantation (surgical); Transplants; Bone-constructs; Cell carrier; Injectable cell carrier; Injectables; Mussel adhesive proteins; Porous microgels; Stem cell therapy; Stem-cell; Sticky porous microgel; Vascularized bone construct; Stem cells ⓘ English 2025 2025-07-01 10.1016/j.cej.2025.163511 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Anode interface-stabilizing dry process employing a binary binder system for ultra-thick and durable battery electrode fabrication ⓘ Polytetrafluoroethylene (PTFE)-based dry process has gained attention in the battery industry owing to their sustainability, cost-effectiveness, and ability to fabricate high loading electrodes. However, the electrochemical instability of PTFE in anodic environments causes significant capacity loss, hindering the development of high-performance dry-processed anodes. In this study, a binary binder system of PTFE and polyvinylpyrrolidone (PVP) is proposed to prevent direct contact between graphite and PTFE, mitigating unwanted interphase evolution. This strategy improves the mechanical integrity of the electrode. It maintains the binding force between the active materials and PTFE binders. PVP also forms a robust inorganic-rich SEI, enhancing Li-ion kinetics and interfacial stability. Consequently, dry-processed graphite with PVP achieved ultra-high loading anodes (similar to 10 mAh cm(-2)) with excellent cycle stability over 200 cycles in full cells coupled with LiNi0.8Co0.1Mn0.1O2 cathodes. This paper presents a cost-effective, high-loading electrode fabrication process and an eco-friendly approach for large-scale electrification. ⓘ Lee, Juhyun; Son, Chae Yeong; Han, Seungmin; Yang, Subi; Kim, Patrick Joohyun; Lee, Dongsoo; Lee, Jung Woo; Ryu, Won-Hee; Choi, Junghyun ⓘ Korea Inst Ceram Engn & Technol, Energy Storage Mat Ctr, Jinju 52851, South Korea; Pusan Natl Univ, Dept Mat Sci & Engn, 2 Busandaehak Ro,63beon Gil, Busan 46241, South Korea; Sookmyung Womens Univ, Dept Chem & Biol Engn, 100 Cheongpa Ro,47 Gil, Seoul 04310, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Gachon Univ, Sch Chem Biol & Battery Engn, 1342 Seongnam Daero, Seongnam 13120, South Korea ⓘ ; Ryu, Won-Hee/F-8375-2014; Hahn, Seung min/MBH-8374-2025; Ryu, Won-Hee/I-4580-2019; Lee, Dongsoo/AAY-4231-2021 ⓘ 59832117900; 58937424300; 58619237900; 58817498700; 57195611779; 57201799820; 57208309536; 36337306800; 59883103900 ⓘ jungwoolee@pusan.ac.kr; whryu@sookmyung.ac.kr; junghchoi@gachon.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 503 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 7.34 2025-05-07 ⓘ 5 6 Lithium-ion battery; Dry-processed graphite anode; High-loading; Polytetrafluoroethylene; Polyvinylpyrrolidone ⓘ LITHIUM; SEI; GROWTH; COST ⓘ Dry-processed graphite anode; High-loading; Lithium-ion battery; Polytetrafluoroethylene; Polyvinylpyrrolidone ⓘ Anodes; Cathodes; Electrochemical electrodes; Gluing; Graphite electrodes; 'Dry' [; Binder systems; Dry process; Dry-processed graphite anode; Electrode fabrication; Graphite anode; High loadings; Ion batteries; Lithium ions; Polyvinylpyrrolidones; Binders ⓘ English 2025 2025-01-01 10.1016/j.cej.2024.158271 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Aqueous hybrid battery with Prussian blue analogue cathode and activated carbon anode in heptyl viologen dibromide electrolyte for enhanced performance and suppressed self-discharge ⓘ Hybrid energy storage devices can simultaneously enhance energy and power density through faradaic and capacitive charging. However, power density is limited by the kinetic imbalance between electrodes due to the slow kinetics of battery-type electrode. In this study, small-sized cobalt hexacyanoferrate (CoHCF) particles with a three-dimensional open framework structure were employed as the cathode to enable fast ion transport. In addition, the anode used activated carbon with lower charge storage capacity than the cathode by increasing its mass and simultaneously adding redox-active heptyl viologen dibromide (HVBr2) to the electrolyte to minimize electrode thickness. The CoHCF//activated carbon hybrid battery achieved a maximum energy density of 44 Wh kg−1 and a maximum power density of 516 W kg−1, utilizing an anode/cathode mass ratio of 2 and HVBr2 electrolyte. These values represent a six-fold increase in energy density and a two-fold increase in power density compared to hybrid battery using inert Na2SO4 electrolyte with the same mass ratio. Furthermore, the adsorption of HV•+ and HVBr2-film on the anode surface suppressed self-discharge and retained 78% of capacity after 72 h. This study developed an aqueous hybrid battery with improved energy and power density by addressing charge storage imbalance between electrodes using mass balance and HVBr2 electrolyte. © 2025 Elsevier B.V. ⓘ Yoo, Seung-Yeop; Park, Jimin; Park, Hye-Seon; Li, Li; Chun, Sang-Eun ⓘ School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, Innovative Semiconductor Education and Research Center for Future Mobility, Kyungpook National University, Daegu, 41566, South Korea, Research Institute of Automotive Parts and Materials, Kyungpook National University, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, Innovative Semiconductor Education and Research Center for Future Mobility, Kyungpook National University, Daegu, 41566, South Korea, Research Institute of Automotive Parts and Materials, Kyungpook National University, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, Innovative Semiconductor Education and Research Center for Future Mobility, Kyungpook National University, Daegu, 41566, South Korea, Research Institute of Automotive Parts and Materials, Kyungpook National University, Daegu, 41566, South Korea; State Key Laboratory of Rolling and Automation, Northeastern University, Shenyang, 110819, China, School of Metallurgy, Northeastern University, Shenyang, 110819, China; School of Materials Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea, Innovative Semiconductor Education and Research Center for Future Mobility, Kyungpook National University, Daegu, 41566, South Korea, Research Institute of Automotive Parts and Materials, Kyungpook National University, Daegu, 41566, South Korea ⓘ ⓘ 59383319800; 59961912400; 59962007000; 56122801700; 36801080300 ⓘ lilicmu@alumni.cmu.edu; sangeun@knu.ac.kr; ⓘ Chemical Engineering Journal ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 519 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 ⓘ 0 ⓘ ⓘ Activated carbon; Cobalt hexacyanoferrate; Hybrid battery; Mass balance; Redox electrolyte; Self-discharge ⓘ Anodes; Bromine compounds; Carbon electrodes; Cathodes; Charge storage; Charging (batteries); Cobalt; Cobalt compounds; Copper compounds; Electrolytes; Fluorine compounds; Secondary batteries; Sulfur compounds; Virtual storage; Cobalt hexacyanoferrate; Dibromides; Energy density; Hybrid battery; Mass balance; Mass ratio; Power densities; Redox electrolytes; Self-discharges; Viologens; Activated carbon ⓘ English Final 2025 10.1016/j.cej.2025.164932 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Biopolymer-supported thin-film composite membranes for reverse osmosis ⓘ Thin-film composite (TFC) membranes are employed in water treatment and thus significantly contribute to environmental remediation efforts. However, the underlying porous support membrane of TFC membranes is fabricated using large amounts of synthetic chemicals and organic solvents, which can adversely affect the environment. Hence, the development of ecofriendly porous membranes is necessary. In this study, we fabricated an all-biopolymer (chitosan (CHS) and cellulose)-based, mechanically robust porous membrane via aqueous solution processes. A porous CHS membrane was formed on cellulose-based traditional Korean paper as a backing fabric through pH-induced aqueous phase separation, followed by chemical crosslinking with pyrogallol, a plant-derived natural compound. The resultant highly porous (overall porosity = 68.1 +/- 1.9%), mechanically reinforced CHS membrane had higher compaction resistance than commercial ultrafiltration membranes under hydrodynamically pressurized conditions (up to 15.5 bar). The prepared CHS membrane was subsequently used as a support for fabricating a TFC membrane via interfacial polymerization.

○ ○ Article ⓘ Characteristics of lithium ion battery with aluminum oxide-coated polyolefin separators employing water-processable terpolymer binder ⓘ Here we report a water-soluble terpolymer, poly[(2-acrylamido-2-methyl-1-propanesulfonic acid)-co-(sodium 4-vinylbenzenesulfonate)-co-acrylonitrile] (PASA), which was synthesized via aqueous solution-based radical polymerization of three comonomers, and its application as a binder for ceramic particles coated on the separator films of lithium ion battery (LIB). The synthesized PASA polymer exhibited a high glass transition temperature higher than ca. 100 degrees C and an initial thermal degradation at 196 degrees C. The PASA polymer as a binder was added to the aqueous slurry of alumina microparticles by varying its content (0-20 wt%), which was then coated on both sides of the polyolefin (PO) separator films. The resulting alumina/PASA (AmPASA)-coated separator films showed high dimensional stability even at ca. 150 degrees C compared to a drastic deformation of the pristine separator films at 150 degrees C. The specific capacity of LIB coin cells was enhanced from 44.6 mAh/g to 49.3 mAh/g by applying the AmPASA-coated PO-separator films (PASA = 2 wt%). The LIBs with the AmPASA-coated PO-separator films (PASA = 2 wt%) showed a well-kept capacity even after cycling for 30 times (0.2-0.4 % reduction only) and normal charging/discharging performances under various C-rates (0.1 C-5 C). ⓘ Lee, Sooyong; Kim, Jihyeon; Park, Dahyeon; Kim, Hwajeong; Kim, Youngkyoo ⓘ Kyungpook Natl Univ, Sch Appl Chem Engn, Dept Chem Engn, Organ Nanoelect Lab, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Chem Engn & Appl Chem, KNU Inst Nanophoton Applicat KINPA, Dept Chem Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Semicond Convergence Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Environm Sci & Technol, Prior Res Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Energy Convergence & Climate Change, Daegu 41566, South Korea ⓘ ⓘ 55421486100; 59189008300; 59924135500; 15520531700; 10340424400 ⓘ khj217@knu.ac.kr; ykimm@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 517 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 0 2025-06-11 ⓘ 0 0 Lithium ion battery; Separator; Stability; Alumina; Binder; Water-soluble polymer ⓘ SAFETY; PERFORMANCE; CHALLENGES ⓘ Alumina; Binder; Lithium ion battery; Separator; Stability; Water-soluble polymer ⓘ Activated alumina; Aluminum coatings; Atom transfer radical polymerization; Binders; Ceramic coatings; Terpolymerization; 150 ° C; Aluminium-oxide; Comonomers; Ion batteries; ITS applications; Lithium ions; Processable; Synthesised; Watersoluble; Watersoluble polymers; Lithium-ion batteries ⓘ English 2025 2025-08-01 10.1016/j.cej.2025.164127 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Crop root exudate-responsive fertilizers fabricated by structural conversion of wastewater activated sludges into phenolic polymer-incorporated mineral-like particles ⓘ Herein, scalable methods are proposed for synthesizing mineral-like particles from wastewater-derived activated sludge through a combination of heat and acid treatment, followed by alkaline precipitation. During the heat/ acid co-treatment, solubilized elements (e.g., P, K, Ca, N, and Fe) and fragmented organic compounds are enriched from the sludge. Subsequently, mineral-like, low-crystalline particles containing high-molecular-weight phenolics are obtained through alkaline precipitation. Compared to raw sludge, these particles exhibit rapid nutrient release in response to citric acid present in crop root exudates. Notably, the nutrient release kinetics driven by the organic acid surpass those induced by the corresponding HCl-driven pH changes, suggesting that the complexation of phenolics and metal ions in the particles is directly disrupted by organic acids, leading to accelerated particle dissolution. Furthermore, lettuce plants capable of secreting organic acids from their roots are shown to grow more rapidly with the synthesized particles than with raw activated sludge or even commercial chemical fertilizer. These findings confirm that enhanced responsiveness to crop root exudates can be achieved by converting activated sludge into materials enriched with inorganic compounds and phenolic polymers, offering significant benefits for agronomic applications. ⓘ Phong, Nguyen Thanh; Kim, Jiwon; Joe, Eun-Nam; Tag, Manar; Lee, Jeong-Gu; Choi, Mira; Jang, Kyoung-Soon; Yoon, Ho Young; Jeon, Jong-Rok ⓘ Gyeongsang Natl Univ, Div Appl Life Sci BK21Plus, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept Appl Life Chem, Jinju 52828, South Korea; Gyeongsang Natl Univ, Inst Agr & Life Sci IALS, Jinju 52828, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Korea Basic Sci Inst, Digital Omics Res Ctr, Cheongju 28119, South Korea; Abo Akad Univ, Lab Nat Mat Technol, Henrikinkatu 2, FI-20500 Turku, Finland; MCE Inc, TIPSTOWN, Daejeon 34126, South Korea ⓘ ⓘ 57204879404; 59560175700; 57224174816; 59559576200; 57204356196; 57203635225; 13007971600; 57210128193; 35229951600 ⓘ hoyoung.yoon@abo.fi; jrjeon@gnu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 507 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 0 2025-05-07 ⓘ 0 0 Root exudate responsiveness; Activated sludges; Crop nutrition; Smart fertilizers; Recalcitrant organic compounds ⓘ ACID-HYDROLYSIS; OXIDATION; LIGNINS; RELEASE ⓘ Activated sludges; Crop nutrition; Recalcitrant organic compounds; Root exudate responsiveness; Smart fertilizers ⓘ Activated sludge; Crop nutrition; Crop roots; Organics; Phenolic polymer; Recalcitrant organic compound; Recalcitrant organics; Root exudate responsiveness; Root exudates; Smart fertilizer ⓘ English 2025 2025-03-01 10.1016/j.cej.2025.160536 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Design and performance of a dual Z-scheme YFeO3/g-C3N5/WO3 heterojunction with enhanced PDS-assisted sonophotocatalytic activity for sulfamethoxazole degradation: Mechanistic insights and ecotoxicity analysis ⓘ In the present study, a double Z-scheme YFeO3/g-C3N5/WO3 (YCW) nanocomposite was successfully synthesized using a simple wet chemical process. The surface morphology, crystal structure, and photosensitive behavior of YCW were characterized using appropriate techniques. Compared to pure and binary nanocomposites, the ternary YCW catalyst prolonged the charge-carrier lifetime and generated large numbers of reactive oxygen species (ROS) via Z-type charge transfer. Moreover, the inclusion of sonication effects with peroxydisulfate (PDS) could potentially enhance the impulsive generation of free radicals via interlinked cavitation bubbles in the reaction medium. The proposed PDS-assisted sonophotocatalytic (SPC) YCW-4 system achieved a sulfamethoxazole (SMX) removal efficiency of 95.6% (k = 0.0438/min), which is higher than that of the SPC-only system (58.1%, k = 0.0151/min) within 60 min of reaction time. The synergistic effects of the SPC/PDS/YCW-4 system reflected the higher utilization of PDS in the effective degradation of SMX into smaller metabolites. To validate the presence of the generated ROS, scavenger tests and electron spin resonance analysis were conducted. The resultant SMX intermediates and their toxicity were elucidated using computational methods. Overall, this study illustrates the considerable potential of the proposed SPC/PDS/YCW-4 system for the effective removal of SMX from contaminated wastewater. ⓘ Jagan, Govindan; Saravanakumar, Karunamoorthy; Cha, Byungjun; Yea, Yeonji; Njaramba, Lewis Kamande; Jang, Min; Yoon, Yeomin; Park, Chang Min ⓘ Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kwangwoon Univ, Dept Environm Engn, 447-1 Wolgye Dong, Seoul 01897, South Korea; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea ⓘ Park, Chang Min/CAA-8506-2022; Kamande, Lewis/JLL-5435-2023 ⓘ 57885044400; 57223020778; 57337280900; 57217304205; 57223183206; 36762550700; 7402126688; 57209588953 ⓘ jaganknu96@knu.ac.kr; kuttysaravana205@knu.ac.kr; chabss72@knu.ac.kr; dpduswl@naver.com; lewiskamande@knu.ac.kr; minjang@kw.ac.kr; yoony@ewha.ac.kr; cmpark@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 510 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 0 2025-05-07 ⓘ 0 0 double Z-type charge transfer; Sonophotocatalysis; PDS activation; Ecotoxicity ⓘ ⓘ double Z-type charge transfer; Ecotoxicity; g-C<sub>3</sub>N<sub>5</sub>; PDS activation; Sonophotocatalysis ⓘ Biodegradation; Doping (additives); Electron spin resonance spectroscopy; Free radical reactions; Free radicals; Reaction intermediates; Double Z-type charge transfer; Ecotoxicity; G-C3N5; Mechanistics; Performance; Peroxydisulfate; Peroxydisulphate activation; Reactive oxygen species; Sonophotocatalysis; Sulfamethoxazole ⓘ English 2025 2025-04-15 10.1016/j.cej.2025.161715 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Diatom derived hollow 3D Frame as a synergetic support for millerite nanoparticles: A unique hydrogen evolution electrocatalyst and its mechanistic insights ⓘ The embedding of metal nanoparticles (NPs) on/into porous supports, including alumina, zeolites, and porous carbon materials, has recently been widely studied to develop advanced catalysts for various energy-related applications. Unlike conventional support materials, diatoms (i.e., Bacillariophyceae), naturally available aluminosilicate materials with a hollow, three-dimensional (3D) porous, durable structure, provide unique opportunities as a support material of metal nanoparticle catalysts for energy-related catalytic applications. Here, we developed an environmentally benign diatom/NiS (Millerite (NiS)) hetero-catalyst for electrocatalytic application. The prepared hetero-composite material was characterized using various analytical methods to understand the structural features and the chemical nature. The diatom/NiS nanocatalyst demonstrated remarkable hydrogen evolution reaction (HER) activity, achieving a low overpotential (53.6 mV) and Tafel slope (55.1 mV dec-1) in sulfuric acid (0.50 M) at-10 mA cm- 2 current density comparable to the commercial noble metal catalyst (Pt/C), which was significantly enhanced than pure NiS. The product (H2) analysis proved the quantitative Faradaic efficiency (99.74 %). The results of the density functional theory (DFT) calculations allow a fundamental understanding of the unique catalytic activity of the material. The DFT calculation results revealed that embedding NiS nanoparticles in diatoms generated effective active sites, resulting in the low Delta GH* (-0.05 eV) for the diatom/NiS heterostructure. Further experiments proved that the heterostructure showed a catalytic activity in oxygen evolution reaction (OER) in a basic medium. This work presents the unique cooperative catalytic behavior of diatom-supported NiS nanoparticle heterostructure, and the proposed strategy can represent the development of a noble eco-friendly electrocatalyst for energy conversion and harvesting. ⓘ Panda, Atanu; Son, Younghu; Umer, Muhammad; Lee, Geunsik; Balamurugan, Mani; Lee, Jihyun; Kim, Wooyul; Umapathi, Reddicherla; Lohith, E.

○ Review ⓘ Dry electrode technology: A new processing paradigm for enhancing performance and sustainability in lithium-based batteries ⓘ Dry electrode technology is rapidly emerging as a transformative approach to address the technical and environmental limitations of conventional wet-slurry processes in lithium-ion batteries (LIBs) and solid-state batteries. By eliminating the use of solvents, this method reduces energy consumption and environmental burden while enabling the fabrication of thick, high-energy-density electrodes with enhanced mechanical stability. This review provides a comprehensive comparison between wet and dry electrode manufacturing, with an emphasis on the microstructural evolution, binder fibrillation behavior, and large-scale process scalability of dry-processed electrodes. Recent advances in dry electrode fabrication for all-solid-state batteries (ASSBs), the use of functional conductive additives, and interfacial challenges associated with dry-processed architectures are critically examined. Key technological highlights include the role of PTFE-based binder fibrillation in forming robust mechanical networks, mitigation strategies for PTFE decomposition under reductive conditions, and the development of bilayer dry-processed solid-state electrolytes to enhance electrochemical and mechanical stability. This review aims to provide a technical roadmap for next-generation battery manufacturing and offers insights into the commercialization challenges and environmental sustainability of dry electrode processing. © 2025 Elsevier B.V. ⓘ Choi, Junghyun; Moon, San; Lee, Dongsoo; Han, Seungmin; Yang, Subi; Jung, Dae Soo; Joo, Jin; Kim, Patrick Joohyun ⓘ School of Chemical, Biological and Battery Engineering, Gachon University, Gyeonggi-do, Seongnam-si, 13120, South Korea; Center for Advanced Battery Materials, Korea Research Institute of Chemical Technology, Daejeon, 34114, South Korea; School of Chemical, Biological and Battery Engineering, Gachon University, Gyeonggi-do, Seongnam-si, 13120, South Korea; Energy Storage Materials Center, Korea Institute of Ceramic Engineering and Technology, Jinju, 52851, South Korea; Energy Storage Materials Center, Korea Institute of Ceramic Engineering and Technology, Jinju, 52851, South Korea, School of Chemical Engineering and Applied Chemistry, Kyungpook National University, Daegu, 41566, South Korea; Energy Storage Materials Center, Korea Institute of Ceramic Engineering and Technology, Jinju, 52851, South Korea; School of Chemical Engineering and Applied Chemistry, Kyungpook National University, Daegu, 41566, South Korea; School of Chemical Engineering and Applied Chemistry, Kyungpook National University, Daegu, 41566, South Korea ⓘ ⓘ 59883103900; 54796797100; 57201799820; 58619237900; 58817498700; 16233760500; 57189617034; 57195611779 ⓘ dsjung@kicet.re.kr; ⓘ Chemical Engineering Journal ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 519 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 ⓘ 0 ⓘ ⓘ Dry electrode; Environmentally friendly; Lithium-ion batteries; Thick electrode; Wet electrode ⓘ Additives; Binders; Electrochemical electrodes; Energy utilization; Environmental technology; Mechanical stability; Solid electrolytes; Solid state devices; Solid-State Batteries; Sustainable development; 'Dry' [; Dry electrode; Electrode technology; Environmentally friendly; Ion batteries; Lithium ions; Mechanical; Performance; Thick electrodes; Wet electrode; Lithium-ion batteries ⓘ English Final 2025 10.1016/j.cej.2025.165044 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Facile manufacturing solutions for ultra-durable flexible MXene micro-supercapacitors in 8-inch scale ⓘ The increasing demand for portable and wearable electronic devices has intensified the need for flexible and miniaturized energy storage solutions. Micro-supercapacitors (MSCs) have emerged as promising candidates due to their high power density, rapid charge-discharge capabilities, and long cycle life. Among various materials, MXenes-two-dimensional transition metal carbides and nitrides-stand out for their exceptional electrical conductivity and tunable surface chemistry. However, scalable fabrication of MXene-based flexible MSCs (fMSCs) remains a challenge. This work presents a facile method for the large-scale production of MXene-based fMSCs, enabling the fabrication of up to 100 devices in a single step. Our approach addresses the limitations of current techniques by offering an efficient and scalable solution that ensures high yield and mechanical robustness. We encountered electrochemical performance degradation during repetitive bending due to weak durability when directly fabricating photomasks onto PI films. This issue was mitigated by introducing a polymer buffer layer, resulting in an increase in volumetric capacitance from 1,093.1F cm- 3 for MXene alone fMSCs to 1,487.7F cm-3 for BLMXene fMSCs (MXene flexible micro-supercapacitors with a buffer layer). Additionally, capacitance retention improved significantly from 24.4 % to 90.3 % after 10,000 bending cycles. Importantly, our findings reveal that using the same material (PVA) for both the buffer layer and the electrolyte significantly enhances device performance and durability. This approach not only benefits MXene-based flexible supercapacitors but also has broad implications for the wider field of supercapacitor research. Improving performance through material compatibility can lead to more efficient and robust energy storage solutions, advancing flexible energy storage devices for industrial and commercial applications. ⓘ Kim, Eunji; Choi, Yunhui; Kim, Hyeong Jin; Jin, Hyeong Min; Oh, Yeon-Wha; Jung, Sanghee; Kang, Il-Suk; Han, Hee; Roh, Jaewoo; Oh, Il-Kwon; Lee, Jinwoo; Ahn, Chi Won; Lee, Yonghee ⓘ Korea Adv Inst Sci & Technol KAIST, Dept Chem & Biomol Engn, 291 Daehak Ro, Daejeon 34141, South Korea; Natl Nano Fab Centetr NNFC, Daejeon 34141, South Korea; Chungnam Natl Univ, Dept Organ Mat Engn, 99 Daehak Ro, Daejeon 34134, South Korea; Chungnam Natl Univ, Dept Mat Sci & Engn, 99 Daehak Ro, Daejeon 34134, South Korea; Korea Adv Inst Sci & Technol KAIST, Dept Mech Engn, 291 Daehak Ro, Daejeon 34141, South Korea; Kyungpook Natl Univ, Dept Nano & Adv Mat Sci & Engn, 2559 Gyeongsang Daero, Sangju 37224, Gyeongsangbuk D, South Korea ⓘ Jin, Hyeong/AAQ-5895-2021; Lee, Jae/G-7717-2012; OH, IL-KWON/B-7121-2011 ⓘ 59602968000; 59463341000; 59863459100; 55079981800; 57543347100; 57837161300; 18535939800; 55661557300; 59383754900; 7101831052; 56007027600; 7201986640; 57348660100 ⓘ jwlee1@kaist.ac.kr; cwahn@nnfc.re.kr; yhlee@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 505 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2024 13.2 3.0 0 2025-05-07 ⓘ 0 0 Flexible devices; Microsupercapacitors; MXenes; Scalable production; Buffer layer ⓘ SOLID-STATE; FABRICATION ⓘ Buffer layer; Flexible devices; Microsupercapacitors; MXenes; Scalable production ⓘ Buffer layers; Buffer storage; Capacitor storage; Electronics devices; Energy; Flexible device; High-power-density; Manufacturing solutions; Microsupercapacitors; Mxene; Rapid charges; Scalable production; Storage solutions; Surface chemistry ⓘ English 2025 2025-02-01 10.1016/j.cej.2024.159109 ⓘ 바로가기 바로가기 바로가기 바로가기
