○ ○ Article ⓘ Enhancing long-term stability and energy/power density of sodium ion battery through fluorination-induced electron density engineering in covalent organic nanosheets ⓘ The structure-related performance of covalent organic nanosheets (CONs) as anode materials in sodium-ion batteries is investigated by the introduction of an electron-withdrawing atom such as fluorine in the unit structure of CON. Then, strong permanent dipoles induced by fluorine are well preserved through the CON framework; these dipoles can provide a large number of accessible sites for Na+ on the self-assembled frameworks. The effect of the dipole on the Na+ storage capacity of fluorinated CON-37 is demonstrated by subsequently comparing that of non-fluorinated CON-35 with respect to various electrochemical behaviors. As a result, the interaction between Na+ and the pi framework of CON-37 is reduced with respect to CON-35 as fluorine could withdraw the electron density of the framework. Therefore, the charging/discharging capacity of CON-37 can be improved as a result of better ion and charge carrier conductivity with high stability for up to 2500 subsequent cycles. Furthermore, its chemical structure is extremely well maintained for up to 2500 cycles. The CON-37 electrode exhibits stable cycling performance and a rate capability, maintaining a highly improved reversible discharge capacity of similar to 350 mA h g(-1) for up to 2500 cycles at a current density of 100 mA g(-1). ⓘ Lee, Minseop; Park, Soohyeon; Bae, Byeonghwak; Jeong, Young Kyu; Oh, Jae-Min; Park, Jin Kuen; Paek, Seung-Min ⓘ Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Hankuk Univ Foreign Studies, Dept Chem, Yongin 17035, Gyeonggi Do, South Korea; Korea Inst Ind Technol, 137-41 Gwahakdanji Ro, Gangneung Si 25440, Gangwon, South Korea; Dongguk Univ, Dept Energy & Mat Engn, Seoul 04620, South Korea ⓘ ; Lee, Minseop/JVZ-7552-2024; Paek, Seung-Min/E-4667-2011 ⓘ 57201550392; 57432261100; 58677460400; 16156681100; 7402155053; 55085701500; 7102686289 ⓘ immrc@kitech.re.kr;jaemin.oh@dongguk.edu;jinkpark@hufs.ac.kr;smpaek@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 477 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 0.77 2025-06-25 ⓘ 8 9 Covalent organic frameworks; Sodium ion batteries; Fluorinations; Charge-discharge capacities; Cycling performances ⓘ OPEN-CIRCUIT VOLTAGE; PERFORMANCE; LI; INTERCALATION; FRAMEWORK; INSERTION; ANODES ⓘ Charge-discharge capacities; Covalent organic frameworks; Cycling performances; Fluorinations; Sodium ion batteries ⓘ Anodes; Carrier concentration; Electric discharges; Electron density measurement; Fluorination; Fluorine; Halogenation; Metal ions; Nanosheets; Anode material; Charge/discharge capacities; Covalent organic frameworks; Cycling performance; Long term stability; Organics; Performance; Power densities; Sodium ion batteries; Structure-related; Sodium-ion batteries ⓘ English 2023 2023-12-01 10.1016/j.cej.2023.147072 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Evaluation of secondary effluent organic matter removal by an in-series forward osmosis-ultrafiltration hybrid process using parallel factor analysis with self-organizing maps ⓘ This study explores removal of effluent organic matter (EfOM) from secondary municipal wastewater effluent by a custom-devised in-series forward osmosis-ultrafiltration (FO-UF) hybrid system in which naturally-driven os-motic pressure, induced by the concentration difference between the feed solution and the draw solution, is a sole driving force for post UF filtration. Water flux and reverse salt flux are greatly affected by concentration and type of draw solution as well as different FO membrane configurations of the active layer facing feed solution (AL-FS) and the active layer facing draw solution (AL-DS). Maximum fluorescence intensity values obtained from parallel factor analysis (PARAFAC) revealed that the FO-UF hybrid process removes EfOM up to 97% of initial con-centration over 2 h experimentation, owing to 6-8% of additional removal by post UF membrane. PARAFAC and self-organizing maps (SOM) modeling revealed that humic-like substances are removed preferentially over protein-like and smaller-sized organics in both AL-FS and AL-DS modes. However, in AL-DS mode, fouling, possibly due to humic-like substances, followed by deteriorating water quality, is observed earlier than in AL-FS mode. During the FO-UF processes, overall properties of EfOM in feed solution are shifted to hydrophilic and smaller-sized organic matter. This work provides a concept of pump-less FO-UF hybrid filtration and demon-strates the proposed system as a feasible option for EfOM removal in water reuse. As the first of its kind, the incorporation of PARAFAC with SOM modeling in FO process gives an insight into the fouling and transport of EfOM in the AL-FS and AL-DS modes. ⓘ Nam, Seong-Nam; Jo, Kyungkeun; Kim, Sewoon; Jun, Byung-Moon; Jang, Min; Park, Chang Min; Han, Jonghun; Heo, Jiyong; Yoon, Yeomin ⓘ Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Korea Army Acad Yeongcheon, Mil Environm Res Ctr, 495 Hoguk Ro, Yeongcheon Si 38900, Gyeongsangbuk D, South Korea; Univ Iowa, Dept Civil & Environm Engn, Iowa City, IA 52242 USA; Korea Atom Energy Res Inst KAERI, Radwaste Management Ctr, 111 Daedeok Daero 989beon Gil, Daejeon 34057, South Korea; Kwangwoon Univ, Dept Environm Engn, 20 Kwangwoon Ro, Seoul 01897, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae Gil, Seoul 03760, South Korea ⓘ Nam, Seong-Nam/ABT-9415-2022; Yoon, Yeomin/KDP-2253-2024; Jang, Min/J-2230-2012; Park, Chang Min/CAA-8506-2022; Jun, Byung-Moon/Y-2134-2019 ⓘ 57226757907; 58160300000; 57201422323; 55326699900; 36762550700; 57209588953; 59803784200; 42461338400; 7402126688 ⓘ jiyongheo@naver.com;yoony@cec.sc.edu; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 464 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 0.77 2025-06-25 ⓘ 8 8 Effluent organic matter; Forward osmosis; Machine learning; Parallel factor analysis; Self-organizing map ⓘ WASTE-WATER TREATMENT; INTERNAL CONCENTRATION POLARIZATION; EEM-PARAFAC-SOM; FLUORESCENCE; REUSE; CLASSIFICATION; IDENTIFICATION; COAGULATION; RECLAMATION; COMPONENTS ⓘ Effluent organic matter; Forward osmosis; Machine learning; Parallel factor analysis; Self-organizing map ⓘ Biogeochemistry; Conformal mapping; Effluents; Hybrid systems; Machine learning; Microfiltration; Multivariant analysis; Organic compounds; Semantics; Ultrafiltration; Water conservation; Water quality; Active Layer; Draw solutions; Effluent organic matter; Feed solution; Forward osmosis; Hybrid process; Machine-learning; Organic matter removal; Parallel factor analysis; Self-organizing-maps; Self organizing maps ⓘ English 2023 2023-05-15 10.1016/j.cej.2023.142640 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Fabrication of highly effective Ag6Si2O7/SmFeO3 heterojunction with synergistically enhanced sonophotocatalytic degradation of ciprofloxacin and production of H2O2: Influencing factors and degradation mechanism ⓘ The design of an effective catalyst for refractory pollutant destruction and H2O2 production remains a major challenge. In this study, a number of novel Ag6Si2O7/SmFeO3 (ASF) heterojunction catalysts were rationally fabricated through an in-situ precipitation strategy. The properties of the fabricated ASF nanocomposites were confirmed through different characterization techniques. In particular, the ASF-1.5 sample exhibits excellent sonophotocatalytic efficiency (94.9%) in an initial ciprofloxacin (CIP) concentration of 10 mg/L, a catalyst dosage of 0.6 g/L, US power of 400 W, pH of 5.0, and US frequency of 40 kHz within 60-min irradiation. Furthermore, the optimized ASF-1.5 sample exhibited the best H2O2 production rate of 258.5 mu M, which was 2.92-fold higher than that of bare Ag6Si2O7. Scavenging experiments demonstrated that (OH)-O-center dot and h(+) were the primary reactive oxidative species (ROS) in the CIP abatement reaction. The synergistic effect of ultrasound and visible light can then promote ROS production, enabling the ASF-1.5 heterojunction to exhibit superior efficiency in CIP degradation and H2O2 generation. Moreover, a tentative sonophotocatalytic mechanism and potential routes for CIP degradation were established. To summarize, this study provides new insights into the rational design of highly effective ASF sonophotocatalysts for clean energy production and ecological applications. ⓘ Yun, Keunyoung; Saravanakumar, Karunamoorthy; Jagan, Govindan; Yea, Yeonji; Yoon, Yeomin; Park, Chang Min ⓘ Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak-ro, Daegu 41566, South Korea; Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Ewha Womans Univ, Dept Environm Sci & Engn, 52 Ewhayeodae-gil, Seoul 03760, South Korea ⓘ ; Yoon, Yeomin/KDP-2253-2024; Park, Chang Min/CAA-8506-2022; Karunamoorthy, Saravanakumar/Q-2005-2016 ⓘ 57884548300; 57223020778; 57885044400; 57217304205; 7402126688; 57209588953 ⓘ sravanan205@gmail.com;cmpark@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 468 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 3.27 2025-06-25 ⓘ 33 34 Ag6Si2O7/SmFeO3; Synergistic effect; Sonophotocatalysis; Ciprofloxacin; H2O2 production ⓘ PHOTOCATALYTIC DEGRADATION; NANOCOMPOSITE; NANOPARTICLES; REDUCTION; OXIDATION; COMPOSITE ⓘ Ag<sub>6</sub>Si<sub>2</sub>O<sub>7</sub>/SmFeO<sub>3</sub>; Ciprofloxacin; H<sub>2</sub>O<sub>2</sub> production; Sonophotocatalysis; Synergistic effect ⓘ Antibiotics; Catalysts; Degradation; Fabrication; Heterojunctions; Iron compounds; Samarium compounds; Silicon; Silver compounds; Ag6si2O7/SmFeO3; Ciprofloxacin; Degradation mechanism; H2O2 production; In-situ precipitation; Property; Reactive oxidative species; Sonophotocatalysis; Synergistic effect; ]+ catalyst; Silicon compounds ⓘ English 2023 2023-07-15 10.1016/j.cej.2023.143491 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Fe-doped kelp biochar-assisted peroxymonosulfate activation for ciprofloxacin degradation: Multiple active site-triggered radical and non-radical mechanisms ⓘ In this study, a novel iron-doped kelp-derived biochar (KBC) (Fe-KBC) was prepared via a combination of hydrothermal carbonization and pyrolysis, characterized, and tested for ciprofloxacin (CIP) degradation via peroxymonosulfate (PMS) activation. The CIP removal in KBC800/PMS was remarkably improved in Fe-KBC800/PMS from 63.38% to 97.48%, under optimised condition (CIP 10 mg L  1, KBC800/Fe-KBC800 0.1 g L  1, PMS 0.5 mM). It was demonstrated that the CIP degradation in Fe-KBC800/PMS was dominantly attributed to the enhanced electron transfer and the generation of radical (SO4 & BULL; ) and non-radical (1O2) species, on the surface reactive sites of Fe-KBC800, such as defects, O  C=O in graphitic structures, and Fe-oxides, which were induced by the doped Fe. Those also suggest that the Fe was doped via substituting H+ in CHx and K+, as well as bonding with O in C  O. The Fe-KBC800/PMS showed an excellent degree of mineralization of CIP and the possible CIP degradation pathways were proposed based on identified intermediates. The performance of Fe-KBC800/PMS was not significantly affected by reuses and co-existing ions, i.e., K+, Na+, Ca2+, Cl , and SO42 , while it was inhibited by Mg2+, HCO3 , H2PO4 , HA, and in natural groundwater, which may affect PMS activation. However, it was greatly enhanced by simply increasing PMS dose. The results in this study provides new insights into the reactions in metal-biochar composites and PMS activation thereby, emphasizing the great potential of Fe-KBC800/PMS in the control of refractory organics in aqueous phase. ⓘ 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; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 471 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 5.96 2025-06-25 ⓘ 54 63 Antibiotics; Electron transfer pathway; Fe -doping; Peroxymonosulfate; Radical; Seaweed derived biochar ⓘ MAGNETIC BIOCHAR; REMOVAL; CARBON; ADSORPTION; OXIDATION; SORPTION; ACID; ANTIBIOTICS; CHEMISTRY; GRAPHENE ⓘ Antibiotics; Electron transfer pathway; Fe-doping; Peroxymonosulfate; Radical; Seaweed derived biochar ⓘ Carbonization; Chemical activation; Electron transitions; Free radical reactions; Groundwater; Iron oxides; Refractory materials; Active site; Biochar; Electron transfer pathways; Fe doping; Fe-doped; Peroxymonosulfate; Peroxymonosulfate activations; Radical; Radical mechanism; Seaweed derived biochar; Antibiotics ⓘ English 2023 2023-09-01 10.1016/j.cej.2023.144519 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Gel polymer electrolyte with improved adhesion property based on poly (4-hydroxybutyl acrylate) for lithium-ion batteries ⓘ Gel polymer electrolytes (GPEs) have emerged as a promising candidate in lithium-ion batteries (LIBs) to address safety issues of liquid electrolytes and to realize flexible batteries. For GPEs, good adhesion between electrolyte and electrodes is highly important to secure performance and stability of the LIBs. Here, new GPEs based on the poly(4-hydroxybutyl acrylate) network are presented. The 4-hydroxybutyl acrylate is a versatile monomer providing excellent adhesion characteristics for various applications, however, there have been no studies for GPEs. We investigated from GPE materials design to their gelation, adhesion, rheology, electrochemical stability, and ion conductivities. In materials design, we gradually controlled liquid content (80-95 vol%) and monomer: crosslinker ratio (99:1-80:20), simultaneously. From the investigation of 16 GPE candidates, we categorized the GPEs based on tan delta change during photopolymerization, into no gelation, viscous gel formation, and stable gel formation. The mechanical properties of the GPEs can be efficiently controlled based on GPE materials design, by showing range of storage modulus from 0.92 kPa to 19.01 kPa. From adhesion characterization, the prepared GPEs indeed present up to 10.92 times higher lap shear strength compared to reference GPEs with conventional ethylene oxide linkage. Also, the GPEs exhibit excellent electrochemical stabilities without significant electrochemical current generation compared to liquid electrolyte, and show reasonable ion conductivities above 10(-3) S center dot cm(-1). We applied GPE8 in half-cell LIB to investigate the electrochemical performance. The initial Coulombic efficiency and discharge capacity were 99.69% and 212.37 mAh center dot g(-1), and exhibited capacity retention of 87.43% upon varied C rate from 0.1 C to 1 C. ⓘ Choi, Hui Ju; Jeong, Yea-Ji; Choi, Hong Soo; Kim, Jun Seop; Ahn, Junho; Shin, Woohyeon; Jung, Byung Mun; Cho, Eunyeong; Lee, Hee Jung; Choi, Jin Hyun; Choi, Min-Jae; Yoon, Jihee; Yi, Jin Woo; Hwang, Geon-Tae; Yoo, Jung-Keun; Chung, Kyeongwoon ⓘ Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Korea Inst Mat Sci KIMS, Composites Res Div, Chang Won 51508, South Korea; Awexomeray Co, Dept Future Technol, Anyang 14056, South Korea; Hankuk Fiber Co Ltd, R&D Ctr, Miryang 50403, South Korea; Ulsan Natl Inst Sci & Technol UNIST, Sch Mat Sci & Engn, Ulsan 44919, South Korea; Yonsei Univ, Dept Chem & Biomol Engn, Seoul 03722, South Korea; Dongguk Univ, Dept Chem & Biochem Engn, Seoul 04620, South Korea; Pukyong Natl Univ, Dept Mat Sci & Engn, Pusan 48513, South Korea; Univ Sci & Technol UST, Adv Mat Engn Div, Daejeon 34113, South Korea ⓘ ; Choi, Min-Jae/AAI-1155-2019 ⓘ 57222315884; 58247114900; 56571739200; 57210185925; 55928966400; 57222326165; 55846388600; 57223973026; 57222316304; 36076723600; 58509938700; 58247519200; 7402731890; 36704574900; 49561920600; 56416916000 ⓘ yoojk@kims.re.kr;kychung@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 474 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 0.58 2025-06-25 ⓘ 6 6 Lithium-ion battery; Gel polymer electrolyte; Poly(4-hydroxybutyl acrylate); Adhesion properties; Materials design ⓘ POLYACRYLONITRILE; PERFORMANCE; CONDUCTIVITY; COPOLYMER; NETWORK; STORAGE ⓘ Adhesion properties; Gel polymer electrolyte; Lithium-ion battery; Materials design; Poly(4-hydroxybutyl acrylate) ⓘ Adhesion; Electric discharges; Ethylene; Gelation; Ions; Monomers; Photopolymerization; Polyelectrolytes; Adhesion properties; Electrochemical stabilities; Electrolyte material; Gel formation; Gel polymer electrolytes; Ion conductivities; Liquid electrolytes; Materials design; Poly(4-hydroxybutyl acrylate); Property-based; Lithium-ion batteries ⓘ English 2023 2023-10-15 10.1016/j.cej.2023.145673 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Green/sustainable strategy for the enhanced thermal destruction of abandoned, lost, discarded fishing gears (ALDFGs) ⓘ One of the most prevalent wastes in the ocean is abandoned, lost, and discarded fishing gears (ALDFGs), which poses a potential mortality risk to all marine creatures. Considering the complex compositional nature and non -biodegradability, the thermal destruction of ALDFGs could offer a strategic measure to abate all hazardous potentials triggered by ALDFGs. More specifically, it is of paramount significance to completely break down ALDFGs into the smallest molecules such as syngas (H2 and CO). Also, the conversion of ALDFGs into the smallest molecular units offer an innovative means for neutralizing toxic chemicals (that are inevitably generated from thermochemical process) given that toxicity is proportional to the degree of aromaticity/substitution of het-eroatoms (S, N, Cl, etc.). To enhance the overall thermal destruction efficiency, carbon dioxide (CO2) was used as a raw material. CO2 was employed as the renewable resource for carbon and oxygen to enhance syngas for-mation. In detail, this study experimentally proved the mechanistic contribution of CO2 to shifting carbon in wax-like/liquid hydrocarbons (HCs) into CO. The formation of CO from catalytic thermal destruction under CO2 condition was 64 times more than from thermal destruction without catalyst under CO2. Before the thermal destruction, the plastic types of ALDFGs (fishing rope (PP/PE), line (nylon 6), and net (PE)) were determined. Also, FT-IR analysis revealed that all plastics components in ALDFGs were partially oxidized. ⓘ Kwon, Dohee; Choi, Dongho; Jung, Sungyup; Chen, Wei-Hsin; Tsang, Yiu Fai; Park, Seong-Jik; Nam, In-Hyun; Kwon, Eilhann E. ⓘ Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Natl Cheng Kung Univ, Dept Aeronaut & Astronaut, Tainan 701, Taiwan; Tunghai Univ, Res Ctr Smart Sustainable Circular Econ, Taichung 407, Taiwan; Natl Chin Yi Univ Technol, Dept Mech Engn, Taichung 411, Taiwan; Educ Univ Hong Kong, Dept Sci & Environm Studies, Hong Kong 999077, Peoples R China; Hankyong Natl Univ, Dept Bioresources & Rural Syst Engn, Anseong 17579, South Korea; Korea Inst Geosci & Mineral Resources KIGAM, Mineral Resources Res Div, Daejeon 34132, South Korea ⓘ Kwon, Eilhann/AGY-3339-2022; Jung, Sungyup/ABE-1493-2021; Tsang, Yiu/AAJ-2524-2020; Park, Seong-Jik/JDN-3009-2023; Chen, Wei-Hsin/S-2033-2018; Nam, In-Hyun/GPP-2752-2022; Choi, Dongho/LTY-8225-2024 ⓘ 57208275497; 57200013497; 55073290800; 57200873137; 22954605700; 34668330800; 7005940659; 9240622100 ⓘ nih@kigam.re.kr;ek2148@hanyang.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 470 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 0.38 2025-06-25 ⓘ 4 4 Marine plastic debris; Ocean waste; Circular economy; Sustainability; Waste-to-energy; CO2 utilization ⓘ HIGH-DENSITY POLYETHYLENE; CO-PYROLYSIS; CATALYTIC PYROLYSIS; PLASTIC WASTE; BIOMASS; BEHAVIOR; DEGRADATION; KINETICS; POLYPROPYLENE; PRODUCTS ⓘ Circular economy; CO<sub>2</sub> utilization; Marine plastic debris; Ocean waste; Sustainability; Waste-to-energy ⓘ Biodegradability; Fisheries; Sustainable development; Synthesis gas; Circular economy; CO2 utilization; Discarded fishing gears; Marine plastic debris; Marine plastics; Ocean waste; Plastic debris; Syn gas; Thermal destruction; Waste to energy; Carbon dioxide ⓘ English 2023 2023-08-15 10.1016/j.cej.2023.144426 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ High-throughput compositional mapping of triple-cation tin-lead perovskites for high-efficiency solar cells ⓘ Mixed tin-lead perovskites suffer from structural instability and rapid tin oxidation; thus, the investigation of their optimal composition ranges is important to address these inherent weaknesses. The critical role of triple cations in mixed Sn-Pb iodides is studied by performing a wide range of compositional screenings over mechanochemically synthesized bulk and solution-processed thin films. A ternary phase map of FA (Sn0.6Pb0.4)I-3, MA(Sn0.6Pb0.4)I-3, and Cs(Sn0.6Pb0.4)I-3 is formed, and a promising composition window of (FA(0.6-x)MA(0.4)Cs(x))Sn0.6Pb0.4I3 (0 <= x <= 0.1) is demonstrated through phase, photoluminescence, and stability evaluations. Solar cell performance and chemical stability across the targeted compositional space are investigated, and FA(0.55)MA(0.4)Cs(0.05)Sn(0.6)Pb(0.4)I(3) with strain-relaxed lattices, reduced defect densities, and improved oxidation stability is demonstrated. The inverted perovskite solar cells with the optimal composition demonstrate a power conversion efficiency of over 22% with an open-circuit voltage of 0.867 V, which corresponds to voltage loss of 0.363 V, promising for the development of narrow-bandgap perovskite solar cells. ⓘ Gunasekaran, Rajendra Kumar; Jung, Jina; Yang, Sung Woong; Yun, Jungchul; Yun, Yeonghun; Vidyasagar, Devthade; Choi, Won Chang; Lee, Chang-Lyoul; Noh, Jun Hong; Kim, Dong Hoe; Lee, Sangwook ⓘ Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu, South Korea; Adv Photon Res Inst APRI, Gwangju Inst Sci & Technol GIST, Gwangju, South Korea; Korea Univ, Sch Civil Environm & Architectural Engn, Green Sch, Seoul, South Korea; Korea Univ, Dept Mat Sci & Engn, Seoul, South Korea; Korea Univ, Dept Mat Sci & Engn, Seoul 02841, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea ⓘ Kim, Dong Hoe/HLQ-5764-2023; Vidyasagar, Devthade/O-3930-2015; Gunasekaran, Rajendra Kumar/ISU-5759-2023; Yun, Yeonghun/KRP-9208-2024; JUNG, Jina/HMD-1392-2023; Lee, Sangwook/O-9166-2015; Noh, Jun/A-7769-2010 ⓘ 57201582809; 57222277455; 58055005400; 58066629400; 57202548363; 57201674442; 57306430400; 57196254178; 11339532400; 56366898500; 57203597324 ⓘ donghoekim@korea.ac.kr;wook2@knu.ac.kr; ⓘ INFOMAT ⓘ INFOMAT ⓘ 2567-3165 5 4 SCIE MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2023 22.7 3.1 3.1 2025-06-25 ⓘ 25 26 compositional engineering; mixed tin-lead iodides; narrow-bandgap perovskites; perovskite solar cells; strain relaxation; ternary phase mapping ⓘ IODIDE PEROVSKITES; STRAIN RELAXATION; PHASE; METHYLAMMONIUM; STABILITY; OXIDATION; VACANCIES; IMPACT; CESIUM; FILMS ⓘ compositional engineering; mixed tin–lead iodides; narrow-bandgap perovskites; perovskite solar cells; strain relaxation; ternary phase mapping ⓘ ⓘ English 2023 2023-04 10.1002/inf2.12393 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Highly porous polyaniline- or polypyrrole-derived carbons: Preparation, characterization, and applications in adsorption ⓘ Nitrogen-doped porous carbons are one of the most fascinating materials with noticeable applications in adsorption/separations, catalysis, supercapacitors, and batteries. Polyaniline (pANI)-or polypyrrole (pPYR)-derived carbons (pADCs or pPDCs, respectively) exhibit very remarkable performances in the liquid-and gas-phase adsorptions because of some unique characteristics including nitrogen-and oxygen-functionalities, very high specific surface area, and tailored porosity. In this report, we reviewed the recent advances in the prepa-ration and characterization of pADC-and pPDC-type materials and their applications in the adsorptive removal/ separation of various chemicals from water, liquid fuel, and air. The preparation procedures and the surface properties of the reported pADC or pPDC adsorbents were explained, with adequate tables. The adsorption re-sults were discussed in terms of the following points: (i) maximum adsorption capacities of the pADCs or pPDCs for a specific adsorbate, (ii) possible adsorbate-adsorbent interactions to understand the adsorption mechanisms, (iii) regeneration of pADC or pPDC adsorbents for recyclability. We believe that this review will provide new scientific perceptions to design/optimize highly porous carbons, especially pADCs or pPDCs, for various appli-cations including adsorption. ⓘ Khan, Nazmul Abedin; Hassan, Mahmud; Lee, Hye Jin; Jhung, Sung Hwa ⓘ East West Univ, Dept Math & Phys Sci, Dhaka 1212, Bangladesh; 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; LEE, HYEJIN/W-1345-2018 ⓘ 35170042700; 59284273900; 56569175200; 6701659467 ⓘ nazmulkhan.du@gmail.com;sung@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 474 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 0.76 2025-06-25 ⓘ 22 22 Adsorption; Carbonization; Polyaniline-derived carbon; Polypyrrole-derived carbon; Review ⓘ METAL-ORGANIC FRAMEWORKS; OXYGEN REDUCTION REACTION; PERSONAL CARE PRODUCTS; N-DOPED CARBON; ACTIVATED CARBON; CO2 ADSORPTION; REMARKABLE ADSORBENT; PERFORMANCE; REMOVAL; NANOTUBES ⓘ Adsorption; Carbonization; Polyaniline-derived carbon; Polypyrrole-derived carbon; Review ⓘ Adsorption; Carbon; Doping (additives); Nitrogen; Polypyrroles; Porous materials; Adsorption separation; Carbonisation; Derived carbons; Liquid phase adsorption; Nitrogen-doped; Performance; Polyaniline-derived carbon; Polypyrrole-derived carbon; Porous carbons; Carbonization ⓘ English 2023 2023-10-15 10.1016/j.cej.2023.145472 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Highly propylene-selective asymmetric mixed-matrix membranes by polymer phase-inversion in sync with in-situ ZIF-8 formation ⓘ Although mixed-matrix membranes (MMMs) have been extensively studied, their commercial applications have been hampered by scientific and engineering challenges. Herein, we report an innovative one-step MMM fabrication method that can put the commercialization of MMMs forward by overcoming most of the current challenges because it enables the rapid formation of high-performance asymmetric MMMs in a scalable manner. The method termed phase-inversion in sync with metal-organic framework (MOF) formation (PIMOF) involves a polymer film undergoing phase inversion and simultaneously ZIF-8 nanoparticles forming in-situ inside the polymer. The resulting MMMs show unexpectedly high C3H6/C3H8 separation performances (C3H6 permeance of ca. 7.5 GPU and C3H6/C3H8 separation factor of ca. 107), which is attributed mostly to the high effective ZIF-8 loading (>50 wt%) and the enhanced molecular sieving effect of the unusually small sub-5 nm ZIF-8 filler nanoparticles by restricted linker motion. ⓘ Hua, Yinying; Park, Sunghwan; Choi, Gyeong Min; Jung, Ho Jin; Cho, Kie Yong; Jeong, Hae-Kwon ⓘ Texas A&M Univ, Artie McFerrin Dept Chem Engn, 3122 TAMU, College Stn, TX 77843 USA; Kyungpook Natl Univ, Sch Energy Mat & Chem Engn, 2559 Gyeongsang Daero, Sangju Si 37224, Gyeongsangbug D, South Korea; Pukyong Natl Univ, Dept Ind Chem, 45 Yongso Ro, Busan 48513, South Korea; Texas A&M Univ, Dept Mat Sci & Engn, 3122 TAMU, College Stn, TX 77843 USA ⓘ ; Hua, Yinying/GRF-1267-2022; Cho, Kie/B-2991-2017 ⓘ 57190427313; 56402062100; 57900808800; 57427225100; 35783987600; 7401619878 ⓘ hjeong7@tamu.edu; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 466 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 1.44 2025-06-25 ⓘ 15 16 Mixed -matrix membranes; Metal -organic frameworks; Zeolitic-imidazolate frameworks; Gas separations; Propylene; propane separation ⓘ HOLLOW-FIBER; GAS; SEPARATION; LAYER; OPPORTUNITIES; POLYSULFONE; PERFORMANCE; CHALLENGES; WET; DRY ⓘ Gas separations; Metal–organic frameworks; Mixed-matrix membranes; Propylene/propane separation; Zeolitic-imidazolate frameworks ⓘ Gas permeable membranes; Metal nanoparticles; Propylene; Semiconducting films; Commercial applications; Engineering challenges; Gas separations; Membrane fabrication; Metalorganic frameworks (MOFs); Mixed-matrix membranes; Phase inversion; Polymer phase; Propylene/propane separation; Zeolitic imidazolate frameworks; Polymer films ⓘ English 2023 2023-06-15 10.1016/j.cej.2023.143048 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Hybrid renewable energy systems involving thermochemical conversion process for waste-to-energy strategy ⓘ Waste-to-energy (WtE) conversion processes integrated with other renewable energy processes (thermochemical hybrid WtE systems) have emerged rapidly as a strategy for simultaneously achieving waste disposal and lessening reliance on fossil fuels. The selection of proper hybrid WtE system configurations is crucial for sustainable and feasible power generation. Understanding the possible configurations of thermochemical waste processing (gasification, pyrolysis, or hydrothermal conversion) and renewable energy technologies (solar thermal, photovoltaics, thermophotovoltaics, solid oxide fuel cells, and anaerobic digestion) is vital for further development and propagation. However, there is a lack of articles that give comparative analysis of the hybrid WtE systems. Herein, we provide a systematic review of existing sustainable energy systems that integrate the thermochemical conversion of various kinds of waste with other renewable energy technologies. The challenges associated with bioenergy-based integrated systems are discussed along with suggestions for future research. ⓘ Lee, Jechan; Lin, Kun-Yi Andrew; Jung, Sungyup; Kwon, Eilhann E. ⓘ Sungkyunkwan Univ, Sch Civil Architectural Engn & Landscape Architect, Suwon 16419, South Korea; Sungkyunkwan Univ, Dept Global Smart City, Suwon 16419, South Korea; Natl Chung Hsing Univ, Dept Environm Engn, Taichung 402, Taiwan; Natl Chung Hsing Univ, Innovat & Dev Ctr Sustainable Agr, Taichung 402, Taiwan; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea ⓘ Lin, Kun-Yi/B-2503-2015; Jung, Sungyup/GZG-6207-2022; Kwon, Eilhann/AGY-3339-2022; Lee, Jechan/J-1229-2016 ⓘ 57188712886; 44961317800; 55073290800; 9240622100 ⓘ ek2148@hanyang.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 452 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 3.06 2025-06-25 ⓘ 83 89 Hybrid system; Renewable energy; Waste valorization; Plastic waste; Organic waste ⓘ MUNICIPAL SOLID-WASTE; OXIDE FUEL-CELL; POWER-GENERATION SYSTEM; LIFE-CYCLE ASSESSMENT; ANAEROBIC-DIGESTION; HYDROTHERMAL LIQUEFACTION; GASIFICATION ENERGY; INCINERATION POWER; ECONOMIC-ANALYSIS; DAIRY WASTE ⓘ Hybrid system; Organic waste; Plastic waste; Renewable energy; Waste valorization; Waste-to-energy ⓘ Anaerobic digestion; Fossil fuels; Renewable energy resources; Solar power generation; Solid oxide fuel cells (SOFC); Waste disposal; Conversion process; Organic wastes; Plastics waste; Renewable energies; Renewable energy technologies; Thermochemical Conversion; Thermochemicals; Waste to energy; Waste valorizations; Waste-to-energy systems; Hybrid systems ⓘ English 2023 2023-01-15 10.1016/j.cej.2022.139218 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Hybridization of the thermo-chemical process of polyvinyl chloride in the production of bioethanol using horse hay ⓘ The improper disposal of polyvinyl chloride (PVC) is hazardous to the environment. To rectify the inappropriate disposal of PVC, this study proposes a sustainable method to valorize hydrogen chloride (HCl) (from the thermolysis of PVC) in bioethanol (BE) production. Prior to saccharification, lignocellulosic biomass (horse hay) was treated with HCl. The optimized parameters for acid treatment were determined from a series of saccharification tests. In detail, the sugar recovery yield was 75 % after 2 % HCl, 120 degrees C, and 2 h treatment of horse hay. In addition, this study suggests that a nitrogen source is required during fermentation to enhance BE productivity. To valorize the residual materials from the saccharification of horse hay and dechlorination of PVC, they were pyrolyzed. Co-pyrolysis of the residues was performed in a CO2 gas environment. The gas-phase reaction of CO2 and volatiles stemming from the two residues was observed, which directly led to the enhanced generation of carbon monoxide (CO). These observations are attributed to the simultaneous redox mechanisms of CO2 and volatiles. To accelerate the reaction rate of the redox mechanisms, catalytic co-pyrolysis of the residues over Co/ SiO2 was performed, and such attempts were confirmed by the enhanced formation of H2 and CO. This study highlights that the hybridization of the thermochemical process of PVC in the production of BE could be a viable approach for waste valorization. ⓘ Lee, Dong-Jun; Cho, Seong-Heon; Park, Jonghyun; Yim, Jun Ho; Jung, Sungyup; Park, Junsu; Tsang, Yiu Fai; Chen, Wei-Hsin; Jeon, Young Jae; Kwon, Eilhann E. ⓘ Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Natl Inst Anim Sci NIAS, Dept Anim Environm, Wonju 55365, South Korea; Pukyong Natl Univ, Dept Microbiol, Busan 48513, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Hong Kong 999077, Peoples R China; Educ Univ Hong Kong, State Key Lab Marine Pollut, Hong Kong 999077, Peoples R China; Natl Cheng Kung Univ, Dept Aeronaut & Astronaut, Tainan 701, Taiwan; Tunghai Univ, Res Ctr Smart Sustainable Circular Econ, Taichung 407, Taiwan; Natl Chin Yi Univ Technol, Dept Mech Engn, Taichung 411, Taiwan; Pukyong Natl Univ, Sch Marine & Fisheries Life Sci, Busan 48513, South Korea ⓘ ; Tsang, Yiu/AAJ-2524-2020; Jung, Sungyup/ABE-1493-2021; Kwon, Eilhann/AGY-3339-2022; Chen, Wei-Hsin/S-2033-2018 ⓘ 57191538179; 56583023200; 58544742000; 57205674301; 55073290800; 57222137944; 22954605700; 57200873137; 7201888480; 9240622100 ⓘ youngjaejeon@pknu.ac.kr;ek2148@hanyang.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 477 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 0.1 2025-06-25 ⓘ 1 1 Circular economy; Waste-to-energy; Biomass valorization; Carbon neutrality; CO 2 utilization ⓘ CO2; INCINERATION; MANAGEMENT; CONVERSION; CATALYSTS; RECOVERY; LITHIUM; LIGNIN; COBALT ⓘ Biomass valorization; Carbon neutrality; Circular economy; CO<sub>2</sub> utilization; Waste-to-energy ⓘ Bioethanol; Carbon dioxide; Carbon monoxide; Dechlorination; Ethanol; Phase interfaces; Polyvinyl chlorides; Pyrolysis; Saccharification; Silicon; Bio-ethanols; Biomass valorizations; Carbon monoxide2 utilization; Carbon neutralities; Circular economy; Copyrolysis; Hybridisation; Hydrogen chloride; Thermo chemical process; Waste to energy; Chlorine compounds ⓘ English 2023 2023-12-01 10.1016/j.cej.2023.146905 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ In-situ pyrolysis of Undaria pinnatifida as a green carbo-catalyst for degradation of organic contaminants: Role of inherent N and P in the degradation pathway ⓘ Tetracycline (TC) is one of the most used antibiotics for human, veterinary medicine, and food additives. The consumption of TC is not thoroughly utilized, and the residual TCs are released from the human and animal bodies by renal excretion. It leads to the accumulation of TC in the environment, which causes adverse effects on the ecosystem. Thus, it is necessary to remove TC from water bodies. The present study demonstrates a singlestep biochar preparation method from seaweed (Undaria pinnatifida) which can be applied for groundwater treatment. Physicochemical characterization of the seaweed-derived biochar (SWBC) reveals that pyrolysis temperature plays a crucial role in peroxymonosulfate (PMS) activation and tetracycline (TC) degradation performance. Complete degradation of TC (10 mg L-1) was achieved in 60 min with 0.5 mM of PMS and 0.1 g L-1 of SWBC pyrolyzed at 800 degrees C (SWBC800). The TC removal trends were further verified by the pseudo- (PFOKM) and two-compartment (TCFOKM) first-order kinetic models. Chemical scavenger experiments and electron spin resonance spectra (ESR) confirmed that both radical (hydroxyl radical, HO center dot, and sulfate radical, SO4 center dot- ) and nonradical (singlet oxygen, 1O2) reactive oxygen species (ROS) formed in the SWBC800/PMS system. The quantification of ROS was calculated to be 2.45 x 10-2, 1.97 x 10-2, and 4.05 x 10-2 mg min-1 for HO center dot, SO4 center dot- , and 1O2, respectively, indicating singlet oxygen is more dominant in the catalytic process. Furthermore, an electrochemical analysis also verified that a non-radical reaction mechanism and an electron-transfer pathway occurred in the SWBC800/PMS system. The SWBC800 catalyst with the PMS system successfully demonstrated reusability in TC degradation. Based on the toxicity analysis SWBC800 is found to be an eco-friendly catalyst for groundwater treatment. ⓘ Annamalai, Sivasankar; Shin, Won Sik ⓘ Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea ⓘ Annamalai, Sivasankar/G-7823-2016 ⓘ 56388546200; 23019870800 ⓘ wshin@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 465 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 2.69 2025-06-25 ⓘ 28 28 Antibiotics; Seaweed biochar; Peroxymonosulfate; Singlet oxygen; Electrochemical analysis ⓘ PEROXYMONOSULFATE ACTIVATION; DOPED GRAPHENE; OXIDATION; TETRACYCLINE; PERSULFATE; NITROGEN; REMOVAL; SULFUR; PHOSPHORUS; NANOTUBES ⓘ Antibiotics; Electrochemical analysis; Peroxymonosulfate; Seaweed biochar; Singlet oxygen ⓘ Additives; Catalysts; Degradation; Electron spin resonance spectroscopy; Free radical reactions; Groundwater; Magnetic moments; Oxygen; Paramagnetic resonance; Pyrolysis; Reaction kinetics; Seaweed; Sulfur compounds; Water treatment; Biochar; Degradation of organic contaminants; Electrochemical analysis; Groundwater treatment; Peroxymonosulfate; Reactive oxygen species; Seaweed biochar; Singlet oxygen; Undaria pinnatifida; ]+ catalyst; Antibiotics ⓘ English 2023 2023-06-01 10.1016/j.cej.2023.142813 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Longitudinally grown pyrolyzed quinacridones for sodium-ion battery anode ⓘ Carbonaceous materials have been actively investigated as anode materials for sodium-ion batteries (SIBs). However, the development of carbonaceous materials that can effectively accommodate large sodium ions within carbon microstructures is highly challenging. In this study, quinacridones (QAs) are used to prepare SIB anode materials via pyrolysis. Among QAs, 2,9-dimethylquinacridone (2,9-DMQA) exhibits prominent morphological development with a high char yield of 61 % at 600 degrees C. Additionally, we reveal that the pyrolysis mechanism and microstructure are significantly affected by the crystal orientation of the precursor. As the 2,9-DMQA has a parallel-oriented crystal structure, the pyrolyzed 2,9-DMQAs grow polycyclic aromatic hydrocarbons with lon-gitudinal microstructures through thermal polymerization initiated by methyl substituents. In addition, the evolution of gas from the 2,9-DMQA precursor induces the reorganization of the carbon framework to form a disordered structure. The anodes fabricated with the 2,9-DMQA pyrolyzed at 600 degrees C (2,9-DMQA-600) show sodium-ion storage performance with a high rate capability (290 mAh/g at a current density of 0.05 A/g) and excellent cycle stability (247 mAh/g at 0.1 A/g after 200 cycles and 134 mAh/g at 5 A/g after 1000 cycles). The well-developed carbon microstructures and surface-confined sodium-ion storage derived from the remaining N -containing and O-containing functional groups provide superior electrochemical performance. ⓘ Chae, Seongwook; Lee, Taewoong; Kwon, Woong; Kang, Haisu; Seo, Hyeok Jun; Kim, Eunji; Jeong, Euigyung; Lee, Jin Hong; Lee, Seung Geol ⓘ Pusan Natl Univ, Sch Chem Engn, 2,Busandaehak Ro 63beon Gil, Busan 46241, South Korea; Kyungpook Natl Univ, Dept Text Syst Engn, 80,Daehak Ro, Daegu 41566, South Korea; Pusan Natl Univ, Dept Organ Mat Sci & Engn, 2, Busandaehak Rro 63beon Gil, Busan 46241, South Korea; Univ Illinois, Dept Chem & Biomol Engn, Urbana, IL 61801 USA ⓘ Lee, Won-Jong/C-1960-2011; Lee, Seung Geol/B-3461-2015 ⓘ 57320497800; 57287573400; 57208867074; 57211014509; 57725265900; 57203571027; 35885596300; 50761132800; 35215858300 ⓘ wolfpack@knu.ac.kr;jinhong.lee@pusan.ac.kr;seunggeol.lee@pusan.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 453 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 1.73 2025-06-25 ⓘ 17 19 Quinacridones; Thermal polymerization; Pyrolysis; Sodium-ion batteries; Active sites ⓘ HIGH-CAPACITY; CARBON NANOFIBERS; DOPED GRAPHENE; STORAGE; ELECTRODES; CYCLABILITY; MECHANISM; INSERTION ⓘ Active sites; Pyrolysis; Quinacridones; Sodium-ion batteries; Thermal polymerization ⓘ Anodes; Carbon; Crystal orientation; Metal ions; Microstructure; Polycyclic aromatic hydrocarbons; Polymerization; Active site; Anode material; Battery anodes; Carbon microstructures; Carbonaceous materials; Dimethylquinacridone; Quinacridone; Sodium ion batteries; Sodium ions; Thermal polymerizations; Pyrolysis ⓘ English 2023 2023-02-01 10.1016/j.cej.2022.139805 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Low-temperature reprogrammable dual light-responsive liquid crystalline elastomer films ⓘ The liquid crystal elastomers (LCEs) possessing azobenzene moieties and boron ester bonds were prepared using Michael addition reaction and photopolymerisation. The azobenzene moieties imparted the LCEs with photoresponsiveness, whereas the boron ester bonds enabled the LCEs to undergo director alignment, reprogramming, and self-healing through a dynamic bond exchange reaction (DBER). This combined strategy overcame the competition between actuation and a DBER at high temperatures, which has been a drawback in the previously developed LCE vitrimers. Interestingly, the developed monodomain LCEs (MLCEs) showed the bending actuation in responsive to both UV and blue lights and unbending motion in responsive to green light, which paves the way for the design of new actuators for biomedical applications. Furthermore, taking advantage of the dynamic nature of boron ester chemistry, bilayer-structured actuators capable of thermo- or photo-controllable bending/ unbending motions were fabricated by welding the MLCE film with a poly(ethylene terephthalate) substrate or itself below their nematic-to-isotropic transition temperatures via a 'glue-free' method. The MLCEs developed in this study can undergo multidirectional movements in response to different stimuli and can be used in applications such as microrobots, untethered biomimetic grippers, and surgical instruments. ⓘ Das, Gautam; Jo, Hyunjin; Park, Soo-Young ⓘ Kyungpook Natl Univ, Sch Appl Chem Engn, Polymer Nano Mat Lab, Daegu 41566, South Korea ⓘ park, soo-young/N-3170-2017 ⓘ 24358918500; 58235142000; 57194041850 ⓘ psy@knu.ac.kr; ⓘ CHEMICAL ENGINEERING JOURNAL ⓘ CHEM ENG J ⓘ 1385-8947 1873-3212 466 SCIE ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL ⓘ 2023 13.4 3.1 1.63 2025-06-25 ⓘ 16 17 Liquid crystalline elastomer; Dynamic bonding; Reprogramming; Photoresponsive; Actuators ⓘ SHAPE-MEMORY BEHAVIOR; NETWORKS; POLYMERS; MODULATION; VITRIMERS ⓘ Actuators; Dynamic bonding; Liquid crystalline elastomer; Photoresponsive; Reprogramming ⓘ Actuators; Addition reactions; Biomimetics; Boron; Chemical bonds; Elastomers; Esters; Ethylene; Functional polymers; Liquid crystals; Medical applications; Photopolymerization; Plastics; Surgical equipment; Azobenzene moiety; Dynamic bonding; Ester bonds; Exchange reaction; Liquid crystal elastomers; Liquid crystalline elastomers; Lows-temperatures; Monodomains; Photo-responsive; Reprogramming; Temperature ⓘ English 2023 2023-06-15 10.1016/j.cej.2023.143368 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Metabolite profiling of Nymphaea rubra (Burm. f.) flower extracts using cyclic ion mobility-mass spectrometry and their associated biological activities ⓘ Nymphaea rubra flowers (NRF) are widely used as a food and in folk medicine throughout the subtropical regions due to their health-promoting characteristics. This study characterized the phytochemical composition of various extracts/fractions of NRF by establishing a quadrupole-cyclic ion mobility-time-of-flight (Q-cIM-TOF) mass spectrometry method in both positive and negative electrospray ionization modes. Over 100 phytoconstituents were tentatively identified, among which 53 phytochemicals belonging to phenolic acids, tannins, flavonoids, terpenoids, alkaloids, xanthones, and naphthopyrones have never been documented in NRF before. Moreover, the ethyl acetate fraction of NRF demonstrated strong antioxidant potential (IC50: 9.21 +/- 0.47 mu g/mL in DPPH assay and 13.65 +/- 0.03 mu g/mL in ABTS assay) and tyrosinase, alpha-glucosidase, and elastase inhibition (IC50: 10.58 +/- 0.20, 2.48 +/- 0.02, and 38.15 +/- 0.25 mu g/mL, respectively). The findings highlight the value of NRF as a source of functional components and broaden its potential applications in the food and nutraceutical industries. ⓘ Naznin, Marufa; Alam, Md Badrul; Alam, Rafiqul;
