| ○ | ○ | Article | Interfacial coupling perovskite CeFeO3 on layered graphitic carbon nitride as a multifunctional Z-scheme photocatalyst for boosting nitrogen fixation and organic pollutants demineralization | The application of pristine graphitic carbon nitride (PCN, g-C3N4)/cerium ferrite (CeFeO3, CFO) composites as photocatalysts for energy production and water treatment has not yet been reported despite its great potential. In this study, CFO, an orthorhombic perovskite-type oxide, was covalently coupled to PCN via a facile single-step calcination strategy. Compared to PCN, optimized 1% CFO-doped PCN (PCN@CFO1) exhibited wide ranges of organic-micropollutant removal (sulfamethoxazole (SMX), atrazine, and bisphenol A) and achieved approximately 49.9% of total-organic-carbon (TOC) removal for SMX in 4 h with 5 stable reusable performances. Further, scavenger experiments and the electron paramagnetic resonance (EPR) spin-trap analysis revealed that PCN@CFO1 could produce superoxide (O-2(-center dot)) and hydroxyl radicals (center dot OH) for organic-pollutant degradation. Meanwhile, the intermediate species of organic pollutants were investigated using liquid chromatography-tandem mass spectrometry to identify the degradation pathways. Of note, PCN@CFO1 achieved up to 573.12 mu mol(-1) g(-1) of ammonia production rate and 2.92% of apparent quantum efficiency of nitrogen photo-fixation at 400 nm, which was 8 times higher than that of PCN. Through coupling CFO and PCN, the flat band potential was found to be upshifted, and a high ratio of the Ce3+ interface associated with oxygen vacancies was generated, resulting in the formation of a Z-scheme system. Remarkably, the formation of the Z-scheme structure on PCN@CFO1 showed enhancement in charge transfer, hydrophilicity, and charge separation, significantly improving the photocatalytic performance for organic-micropollutant demineralization and nitrogen photo-fixation under UVA-LED (400 nm) light irradiation. Our study provided a facile and scalable preparation strategy for multifunctional photocatalysts that could be effectively activated under energy-efficient UVA-LED irradiation for energy production and emerging pollutants degradation. | Choong, Choe Earn; Park, Chang Min; Chang, Yoon-Young; Yang, Jae-kyu; Kim, Jung Rae; Oh, Sang-Eun; Jeon, Byong-Hun; Choi, Eun Ha; Yoon, Yeomin; Jang, Min | Kwangwoon Univ, Dept Environm Engn, Seoul 01897, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Pusan Natl Univ, Sch Chem Engn, 63 Busandeahak Ro, Busan 46241, South Korea; Kangwon Natl Univ, Dept Biol Environm, 192-1 Hyoja Dong, Gangwon Do 200701, Chuncheon Si, South Korea; Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kwangwoon Univ, Plasma Biosci Res Ctr, Dept Elect & Biol Phys, Seoul 01897, South Korea; Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA | Choong, Choe Earn/J-3005-2016; Jeon, Byong-Hun/AAF-4352-2020; Kim, Jung/N-8018-2013; Park, Chang Min/CAA-8506-2022; Jang, Min/J-2230-2012; Choi, Eun/AFN-9488-2022; Yoon, Yeomin/KDP-2253-2024 | 57200944393; 57209588953; 7501839950; 57218109558; 8545413900; 7404103316; 57653536800; 56570733500; 7402126688; 36762550700 | minjang@kw.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 427 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 4.08 | 2025-06-25 | 64 | 66 | Perovskite; Carbon graphitic nitride; Z-scheme; Photocatalysis | SURFACE; OXYGEN; CONSTRUCTION; EVOLUTION; G-C3N4; CO2 | Carbon graphitic nitride; Perovskite; Photocatalysis; Z-scheme | Amines; Ammonia; Carbon nitride; Cerium compounds; Charge transfer; Computer software reusability; Electron spin resonance spectroscopy; Energy efficiency; Image enhancement; Iron compounds; Irradiation; Liquid chromatography; Magnetic moments; Mass spectrometry; Nitrogen fixation; Organic carbon; Paramagnetic resonance; Perovskite; Photocatalytic activity; Photodegradation; Water treatment; Demineralisation; Energy productions; Graphitic carbon nitrides; Interfacial couplings; Organic micropollutants; Organics; Orthorhombic perovskite-type oxide; Single-step; Sulfamethoxazole; Z-scheme; Organic pollutants | English | 2022 | 2022-01-01 | 10.1016/j.cej.2021.131406 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Metal-free oxidative desulfurization with molecular oxygen by using N-enriched porous carbons derived from ionic liquid-loaded covalent-organic polymer | A microporous triazine polymer (MCTP) was prepared and loaded, for the first time, with an N-containing ionic liquid (IL) through a ship-in-a-bottle method. The composite material, IL@MCTP, was pyrolyzed under high temperature to get N-enriched carbonaceous materials. The obtained carbons (denoted ICDCs) were utilized as a metal-free catalyst for the aerobic oxidative desulfurization (ODS) of organic sulfur compounds like dibenzo-thiophene from a model fuel. The reactivity of ICDCs in ODS was dependent on the nitrogen content and porosity of the carbons. One selected material (ICDC(8)), because of high nitrogen content and adequate porosity, showed a remarkable performance in ODS or removal of dibenzothiophene with a very low activation energy of 23.7 kJ/ mol. Radical scavenger experiments and ESR analysis revealed the important role of superoxide anion radicals (center dot O-2(-)) in oxidation. A plausible reaction mechanism to suggest an important role of nitrogen species in ICDCs to activate O-2 (via adsorption on C with a partial positive charge) was proposed. The ODS also can be carried out with air, and the catalyst was reusable for up to the fifth cycle by simple solvent washing. The ICDCs can be a competitive and environment-friendly (metal-free) ODS catalyst, especially using cheap oxidants like air or O-2. | Ahmed, Imteaz; Kim, Chul-Ung; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Korea Res Inst Chem Technol KRICT, Chem & Proc Technol Div, POB 107,141 Gajeong Ro, Yuseong 34114, Daejeon, South Korea | Jhung, Sung/AAO-6683-2021 | 55377179600; 9742142700; 6701659467 | sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 450 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 1.51 | 2025-06-25 | 23 | 25 | Covalent-organic polymers; Doped nitrogen; Metal-free oxidation; Oxygen; Oxidative desulfurization; Pyrolyzed carbon | REDUCED GRAPHENE OXIDE; FREE CATALYST; EXTRACTIVE DESULFURIZATION; SULFUR-COMPOUNDS; DIESEL FUEL; ADSORPTION; NITRIDE; DENITROGENATION; EFFICIENT; OILS | Covalent-organic polymers; Doped nitrogen; Metal-free oxidation; Oxidative desulfurization; Oxygen; Pyrolyzed carbon | Activation energy; Bottles; Carbon; Catalysts; Ionic liquids; Metals; Nitrogen removal; Porosity; Porous materials; Sulfur compounds; Covalent-organic polymer; Dibenzothiophenes; Doped nitrogen; Metal free; Metal-free oxidation; Microporous; Oxidative desulfurization; Porous carbons; Pyrolyzed carbon; ]+ catalyst; Nitrogen | English | 2022 | 2022-12-15 | 10.1016/j.cej.2022.138416 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Nitrogen-doped MoS2 as a catalytic sulfur host for lithium-sulfur batteries | Lithium-sulfur batteries (LSBs) are the leading candidates for the next-generation lithium-ion batteries because of their large energy densities and low price. However, LSBs have a critical problem in that specific capacity continuously decreases due to the shuttle effect, so it has not been commercialized. Herein, we propose an N doped MoS2 composite (nMC) with the dual functions of a chemisorption host and a conversion catalyst to inhibit the shuttle effect and thus improve the scalability of LSBs. The nMC increases the chemisorption energy of lithium polysulfide and promotes electron transfer, resulting in improved cycle stability and electrochemical performance. In addition, it controls the redox kinetics of lithium polysulfides by acting as a catalyst of the cathode. The nMC cathode accelerates the reaction rates by reducing the activation energy barrier of the Li2Sn to Li2S conversion and inhibits the shuttle effect by rapidly reducing highly soluble Li2Sn. Consequently, we developed the N-doped MoS2 composite, a catalytic host material for LSBs, that provides high initial capacity, outstanding cycle stability, and fast charging ability as cathode materials of LSBs. Especially, LSBs based on S@nMC cathode demonstrate high cycle stability with a low-capacity decay rate of 0.025% per cycle after 1000 cycles. | Cho, Jinil; Ryu, Seokgyu; Gong, Yong Jun; Pyo, Seonmi; Yun, Heejun; Kim, Heebae; Lee, Jeewon; Yoo, Jeeyoung; Kim, Youn Sang | Seoul Natl Univ, Grad Sch Convergence Sci & Technol, Program Nano Sci & Technol, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Seoul Natl Univ, Inst Chem Proc, Coll Engn, Sch Chem & Biol Engn, Seoul 08826, South Korea; Adv Inst Convergence Technol, Suwon 16229, South Korea; Seoul Natl Univ, Inst Chem Proc, Coll Engn, Seoul 08826, South Korea | Yoo, Jeeyoung/AAH-1359-2019; Kim, SoW/ABB-7917-2021; Cho, Hyuk/AAU-7753-2020 | 57209801309; 57192435552; 57203432769; 57211858131; 57218197755; 57217054648; 57339274800; 56046607500; 8938854200 | jyoo@knu.ac.kr;younskim@snu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 439 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 2.58 | 2025-06-25 | 40 | 42 | Lithium-sulfur batteries; Conversion cathode; Nano-MoS(2 )catalyst; Chemisorption; Shuttle effect; DFT calculation | COMPOSITE SEPARATOR; ION BATTERIES; TRANSITION; FUNCTIONALIZATION; POLYSULFIDES; CHALLENGES; MOLECULES; DESIGN; LAYERS | Chemisorption; Conversion cathode; DFT calculation; Lithium-sulfur batteries; Nano-MoS<sub>2</sub> catalyst; Shuttle effect | Activation energy; Binary alloys; Carbon nanofibers; Cathodes; Charging (batteries); Chemisorption; Doping (additives); Layered semiconductors; Lithium compounds; Lithium-ion batteries; Molybdenum compounds; Nanosheets; Nitrogen; Polysulfides; Reaction rates; Sulfur compounds; Conversion cathode; Cycle stability; DFT calculation; Lithium/sulfur batteries; MoS 2; N-doped; Nano-MoS2 catalyst; Polysulphides; Shuttle effect; ]+ catalyst; Lithium sulfur batteries | English | 2022 | 2022-07-01 | 10.1016/j.cej.2022.135568 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Photobiocidal-triboelectric nanolayer coating of photosensitizer/ silica-alumina for reusable and visible-light-driven antibacterial/antiviral air filters | Outbreaks of airborne pathogens pose a major threat to public health. Here we present a single-step nanocoating process to endow commercial face mask filters with photobiocidal activity, triboelectric filtration capability, and washability. These functions were successfully achieved with a composite nanolayer of silica-alumina (Si-Al) sol-gel, crystal violet (CV) photosensitizer, and hydrophobic electronegative molecules of 1H, 1H, 2H, 2H-per-fluorooctyltriethoxysilane (PFOTES). The transparent Si-Al matrix strongly immobilized the photosensitizer molecules while dispersing them spatially, thus suppressing self-quenching. During nanolayer formation, PFOTES was anisotropically rearranged on the Si-Al matrix, promoting moisture resistance and triboelectric charging of the Si-Al/PFOTES-CV (SAPC)-coated filter. The SAPC nanolayer stabilized the photoexcited state of the photosensitizer and promoted redox reaction. Compared to pure-photosensitizer-coated filters, the SAPC filter showed substantially higher photobiocidal efficiency (-99.99 % for bacteria and a virus) and photo-durability (-83 % reduction in bactericidal efficiency for the pure-photosensitizer filter but-0.34 % for the SAPC filter after 72 h of light irradiation). Moreover, after five washes with detergent, the SAPC filter maintained its photobiocidal and filtration performance, proving its reusability potential. Therefore, this SAPC nanolayer coating provides a practical strategy for manufacturing an antimicrobial and reusable mask filter for use during the ongoing COVID-19 pandemic. | Jeong, Sang Bin; Lee, Dong Uk; Lee, Byeong Jin; Heo, Ki Joon; Kim, Dong Won; Hwang, Gi Byoung; MacRobert, Alexander J.; Shin, Jae Hak; Ko, Hyun Sik; Park, Se Kye; Oh, Yong Suk; Kim, See Jo; Lee, Dong Yun; Lee, Seung-Bok; Park, Inyong; Kim, Sang Bok; Han, Bangwoo; Jung, Jae Hee; Choi, Dong Yun | Sejong Univ, Dept Mech Engn, Seoul 05006, South Korea; Korea Inst Sci & Technol, Ctr Environm Hlth & Welf Res, Seoul 02792, South Korea; Pukyong Natl Univ, Dept Ind Chem, Busan 48513, South Korea; Korea Inst Ind Technol, Biomed Mfg Technol Ctr, Yeongcheon 38822, South Korea; Andong Natl Univ, Sch Mech Engn, Andong 36729, South Korea; UCL, Mat Chem Res Ctr, Dept Chem, London WC1H 0AJ, England; Gyeongsang Natl Univ, Res Inst Green Energy Convergence Technol, Jinju 52828, South Korea; UCL Div Surg & Intervent Sci, Royal Free Campus, London NW3 2PF, England; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Korea Adv Inst Sci & Technol, Dept Mech Engn, Daejeon 34141, South Korea; Korea Inst Machinery & Mat, Dept Environm Machinery, Daejeon 34103, South Korea | ; Lee, Dong Uk/JFK-4156-2023; Hwang, Gi Byoung/AAB-9733-2022; Han, Bangwoo/AAE-5550-2020; Jung, Jae Hee/HTM-4275-2023; Oh, YongSuk/KIK-1174-2024; Choi, Dong Yun/HRD-1551-2023 | 57208903386; 57218710149; 57544771100; 56313445200; 36066372400; 35778301700; 26643365600; 57355464800; 57208902803; 57210575824; 7402125895; 7601601028; 57211001605; 55716391200; 55456477100; 14032753100; 7401726262; 14919395900; 55566743200 | jaehee@sejong.ac.kr;dychoi311@kitech.re.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 440 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 1.95 | 2025-06-25 | 28 | 31 | COVID-19; Visible light; Photobiocidal activity; Antimicrobial filters; Antiviral filters; Nanocoatings | CRYSTAL VIOLET; SINGLET OXYGEN; TRANSMISSION | Antimicrobial filters; Antiviral filters; COVID-19; Nanocoatings; Photobiocidal activity; Visible light | Alumina; Efficiency; Health risks; Light; Molecules; Photosensitizers; Redox reactions; Reusability; Silica; Sols; Viruses; Antimicrobial filter; Antiviral filter; Antivirals; COVID-19; Nano layers; Nano-coatings; Photobiocidal activity; Photosensitiser; Silica-alumina; Visible light; Aluminum oxide | English | 2022 | 2022-07-15 | 10.1016/j.cej.2022.135830 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Polysaccharide-derivative coated intravascular catheters with superior multifunctional performance via simple and biocompatible method | Antimicrobial, antithrombotic activity and low-friction functions are essential for the surface of intravascular catheters (ICs). However, the multifunctional surface, encompassing all of the above properties has not yet been realized. Here, we report a novel strategy for biocompatible and eco-friendly surface modification of the ICs with multifunctional polysaccharide, O-carboxymethyl chitosan (CMC). Micro-and nanoscale porous CMC (p-CMC) layer was simply fabricated via a selective elimination of the water-soluble polyethylene glycol (PEG) from heterogeneous CMC/PEG composite. The p-CMC structure exhibited a significantly enhanced hydration rate and superhydrophilic property. In particular, the antifouling property of superhydrophilic surface showed excellent anti-adhesion of Escherichia coli and platelets along with the intrinsic multifunctionality of CMC, indicating a dual effect of our p-CMC layer: (1) intrinsic antibacterial and antithrombotic properties of CMC and (2) anti-adhesion of substances on superhydrophilic surface. Meanwhile, despite the rough surface of the p-CMC layer, it showed high lubricity and durability under continuous wet friction conditions. Furthermore, we demonstrated that the actual p-CMC coated intravascular catheter (IC) provides superior trackability in a curved artificial blood vessel. The potential of the proposed coating strategy can be offered not only ICs, but also wide range of polymer-based applications including vascular filters, grafts, pacemakers and soft robots. | Park, Se Kye; Shin, Jae Hak; Jung, Jae Hee; Lee, Dong Yun; Choi, Dong Yun; Yoo, Seung Hwa | Korea Inst Ind Technol, Daegyeong Div, Yeongcheon Si, Gyeongsangbuk D, South Korea; Sejong Univ, Dept Mech Engn, Seoul, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu, South Korea; Jeonbuk Natl Univ, Dept Quantum Syst Engn, Jeonju Si, Jeollabuk Do, South Korea | Choi, Dong Yun/HRD-1551-2023; Jung, Jae Hee/HTM-4275-2023 | 57210575824; 57355464800; 14919395900; 57211001605; 55566743200; 57190001859 | dongyunlee@knu.ac.kr;dychoi311@kitech.re.kr;seunghwayoo@jbnu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 433 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 1.38 | 2025-06-25 | 21 | 23 | Multifunctional coatings; Polysaccharide; Vascular devices; Antimicrobial activity; Antithrombotic activity; Low-friction | CARBOXYMETHYL CHITOSAN; ANTIMICROBIAL PROPERTIES; COATINGS; SURFACE; THROMBOSIS; ANTIBIOFILM; STRATEGIES; ADHESION; COMPLEX | Antimicrobial activity; Antithrombotic activity; Low-friction; Multifunctional coatings; Polysaccharide; Vascular devices | Adhesion; Biocompatibility; Blood vessels; Coatings; Escherichia coli; Friction; Integrated circuits; Anti-microbial activity; Anti-thrombotic activities; Antiadhesion; Intravascular; Low friction; Multifunctional coatings; O-carboxymethyl chitosans; Property; Superhydrophilic surface; Vascular device; Catheters | English | 2022 | 2022-04-01 | 10.1016/j.cej.2022.134565 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Portable integrated photo-charging storage device operating at 3 V | The integration of an energy harvesting device and an energy storage device into one unit has been widely studied as a distributed power source. Herein, we propose a high-voltage-driven photo-charging storage device, integrating a series-connected perovskite solar cell and an ionogel-based solid supercapacitor. The photo -charging storage device exhibits high overall efficiencies of 13.17 % and 9.87 % at 1 mA cm-2 and 20 mA cm(-2), respectively, attributed to its high storage efficiency of over similar to 70 % at all discharge current densities. This high discharge current density of 20 mA cm(-2) is the record value for all reported integrated solar cells and electric double-layer capacitor systems. Moreover, the photo-charging storage device maintains 78.6 % of its overall efficiency after 100 cycles under AM 1.5 G illumination and exhibits remarkable cycle performance under indoor light illumination. To understand the interfacial behavior of the photo-charging storage device, impedance spectroscopy is performed for the first time. In addition, to avoid the decomposition of the perovskite solar cell active layer with moisture, an encapsulation process is conducted, which enables the device to remain operational at 3 V after 8 weeks. These results underline the high potential of this photo-charging storage device as a portable power source. | Han, Juyeon; Lee, Junyeong; Jang, Eunbin; Kim, Myeongjin; Cha, Hyojung; Jo, Sungjin; Yoo, Jeeyoung | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea | Yoo, Jeeyoung/AAH-1359-2019 | 57222146622; 58853044900; 57837176500; 55541419000; 35885242200; 7101724027; 56046607500 | sungjin@knu.ac.kr;jyoo@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 450 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 0.31 | 2025-06-25 | 5 | 5 | Supercapacitors; Perovskite solar cells; Monolithic integration; Photo-charging storage devices; Indoor charging | PEROVSKITE SOLAR-CELLS; SOLID-STATE SUPERCAPACITOR; GEL POLYMER ELECTROLYTE; ENERGY-CONVERSION; IMPEDANCE SPECTROSCOPY; PERFORMANCE; EFFICIENT; VOLTAGE; PHOTOCAPACITOR; CAPACITANCE | Indoor charging; Monolithic integration; Perovskite solar cells; Photo-charging storage devices; Supercapacitors | Energy harvesting; Monolithic integrated circuits; Perovskite; Perovskite solar cells; Storage efficiency; Virtual storage; Discharge current density; Distributed power sources; Energy harvesting device; High-voltages; Indoor charging; Monolithic integration; Overall efficiency; Photo-charging storage device; Photocharging; Series-connected; Supercapacitor | English | 2022 | 2022-12-15 | 10.1016/j.cej.2022.138463 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Probiotic strategy for biofouling control through direct injection of quorum-quenching bacteria into membrane bioreactors | In membrane bioreactors (MBRs), N-acyl homoserine lactones (AHLs)-related quorum sensing (QS) has been described as one of the main causes of biofouling during wastewater treatment. Quorum-quenching (QQ) bacteria for the mitigation of QS in MBRs have been applied but limited to entrapping methods only. Thus, this study investigates the direct injection of different doses (0-77.2 mg/d) of unentrapped QQ strains (Rhodococcus sp. BH4) into a probiotic QQ MBR (i.e., bioaugmented reactor) while monitoring the changes in fouling rates as well as microbial communities, biopolymers, signal molecules, and treatment performances. The QQ bacteria show effective biofouling mitigation in diverse MBR phases, but a halt in QQ bacteria injection leads to increased fouling rates in the probiotic QQ MBR. The QQ bacteria exhibit a noticeable AHL degradation rate during BH4 inoculation as opposed to when inoculation is halted. They also have significant inhibitory effects on the generation of soluble carbohydrates and proteins. However, cell-bound extracellular polymeric substance (EPS) concentrations are relatively higher in the probiotic QQ reactor despite decreased fouling rates. This can be ascribed to the production of EPS by injected BH4, as revealed in pure BH4 batch cultures. Probiotic QQ has impacts on both the relative bacterial abundance and the overall microbial composition. Thiothrix is identified as the most dominant genus in the mixed liquor of both MBRs; however, its relative abundance becomes low in the probiotic MBR during QQ bacteria injection. These findings provide valuable information that will foster the development of improved QQ strategies in MBRs. | Shu, Neh Nyong; Park, Hyeona; Shah, Syed Salman Ali; Mameda, Naresh; Yoo, Hyun Jin; Min, Junhong; Angelidaki, Irini; Choo, Kwang-Ho | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; Chung Ang Univ, Sch Integrat Engn, 84 Heukseok Ro, Seoul 06974, South Korea; Tech Univ Denmark, Dept Chem & Biochem Engn, DK-2800 Lyngby, Denmark; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Inst Water Ind, 80 Daehak Ro, Daegu 41566, South Korea | Mameda, Naresh/AAV-2711-2020; Mameda, Dr. Naresh/AAV-2711-2020; Angelidaki, Irini/AAX-2562-2020; Choo, Kwang-Ho/A-3456-2016; Shah, Syed Salman Ali/JCE-1663-2023 | 57475365300; 57213039681; 57215722996; 57192214360; 57200194198; 7201919986; 6603674728; 7102083272 | chookh@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 438 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 0.94 | 2025-06-25 | 15 | 15 | Membrane biofouling; Microbial community; Rhodococcus sp; BH4; Quorum quenching; Quorum sensing | SOLUBLE MICROBIAL PRODUCTS; MUNICIPAL WASTE-WATER; BIOFILM FORMATION; SENSING SIGNALS; COMMUNITY; MBR; PERFORMANCE; AEROMONAS; AUTOINDUCER-2; INHIBITION | Membrane biofouling; Microbial community; Quorum quenching; Quorum sensing; Rhodococcus sp.

| ○ | ○ | Article | Relationships between phase transition and quality characteristics of cooked rice during storage | The objective of this study was to determine crystalline structures, phase transitions, textural properties, and morphological characteristics of cooked rice with different amylose contents during storage at 4 degrees C for 14 days. Moisture content of cooked rice decreased from 64.8% to 60.2% during storage. Relative crystallinity increased during storage, indicating an increase in ordered structure by starch recrystallization. During the storage, ice freezing and ice melting enthalpies of cooked rice decreased and glass transition temperature (Tg ') increased. Inner structure of cooked rice showed smaller holes and a thicker surrounding matrix in waxy or non-waxy rice varieties and polyhedral structure in high-amylose variety. Ice melting enthalpy of cooked rice was positively and negatively correlated with hardness and adhesiveness, respectively. Tg ' was positively correlated with adhesiveness. These results indicate that phase transitions of cooked rice with different amylose contents were significantly related to their crystalline structures, morphologies, and textures during storage. | Jeong, Duyun; Zhang, Chen; Ha, Mingyo; Chung, Hyun-Jung | Kyungpook Natl Univ, Dept Food & Food Serv Ind, Sangju 37224, South Korea; Yangzhou Univ, Sch Food Sci & Engn, Huayang Xilu 196, Yangzhou 225127, Jiangsu, Peoples R China; Chonnam Natl Univ, Div Food & Nutr, Gwangju 61186, South Korea | 57203059723; 57254740100; 57759295500; 7404006790 | djeong@knu.ac.kr;zhangchen@yzu.edu.cn;mingyo653@gmail.com;hchung@jnu.ac.kr; | FOOD HYDROCOLLOIDS | FOOD HYDROCOLLOID | 0268-005X | 1873-7137 | 132 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY | 2022 | 10.7 | 3.2 | 0.68 | 2025-06-25 | 6 | 9 | Cooked rice; Amylose content; Phase transition; Morphology; Texture | STARCH RETROGRADATION; GLASS-TRANSITION; AMYLOSE CONTENT; MILLED RICE; TEMPERATURE; COOKING; MICROSTRUCTURE; BEHAVIOR; TEXTURE; SUGARS | Amylose content; Cooked rice; Morphology; Phase transition; Texture | English | 2022 | 2022-11 | 10.1016/j.foodhyd.2022.107874 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Remarkable adsorption for hazardous organic and inorganic contaminants by multifunctional amorphous core-shell structures of metal-organic framework-alginate composites | Novel metal-organic framework-alginate composite beads (CA-MIL-53-AC) were synthesized using sodium alginate (gelling agent) and calcium chloride (complexing agent) via a one-pot and dropping method to selectively remove the dichlorodiphenyltrichloroethane (DDT), arsenate (As(V)), and fluoride in an aqueous solution. To evaluate the characteristics of the synthesized composite beads, scanning electron microscopy, X-ray diffraction, Fourier-transform infrared, X-ray photoelectron spectroscopy, thermal gravimetric analysis, zeta potential, and porosimetry techniques were used in this study. The adsorption kinetics showed that DDT, As(V), and fluoride removal could be described by the pseudo-first-order model. Also, the adsorption isotherms indicated that DDT and As(V)/fluoride removal followed the Langmuir and Freundlich models, respectively. Compared with granular AC and pristine CA, CA-AC, and CA-MIL-53, the CA-MIL-53-AC showed superior adsorption performance for all target contaminants (5.29, 4.89, and 3.18 mg/g for DDT, As(V), and fluoride, respectively). The adsorptive behavior for DDT was spontaneous, exothermic, and highly favorable based on thermodynamics calculations. Furthermore, the regenerated composite beads showed high removal capacity for DDT after the third recycle. The continuous DDT adsorption in the fixed-bed column at different flow rates were well fitted using Thomas, Adams-Bohart, and Yoon-Nelson models. The plausible mechanisms for the DDT, As (V), and fluoride removal by CA-MIL-53-AC were identified as hydrophobic and pi-pi interactions, ion exchange, surface complexation, and hydrogen bonding. These findings provide significant insight to remove DDT, As(V), and fluoride from water for practical applications. | Njaramba, Lewis Kamande; Kim, Sewoon; Kim, Yejin; Cha, Byungjun; Kim, Nahyun; 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 | Kim, Tae Hyun/GNP-3195-2022; Kamande, Lewis/JLL-5435-2023; Yoon, Yeomin/KDP-2253-2024; Park, Chang Min/CAA-8506-2022 | 57223183206; 57201422323; 59052467200; 57337280900; 57336446400; 7402126688; 57209588953 | lewiskamande@gmail.com;sewoon@email.sc.edu;rysa12@naver.com;skgusskgus12@naver.com;yoony@cec.sc.edu;cmpark@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 431 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 3.08 | 2025-06-25 | 47 | 50 | MIL-53(Al); Alginate, DDT; As(V); Fluoride; Adsorption | DRINKING-WATER; MIL-53 AL; REMOVAL; FLUORIDE; OXIDE; NANOPARTICLES; GROUNDWATER; PERFORMANCE; CHEMISTRY; NITRATE | Adsorption; Alginate, DDT; As(V); Fluoride; MIL-53(Al) | Calcium chloride; Fluorine compounds; Hydrogen bonds; Ion exchange; Scanning electron microscopy; Sodium alginate; Thermodynamics; Thermogravimetric analysis; X ray photoelectron spectroscopy; Alginate, dichlorodiphenyltrichloroethane; As(V); Composite beads; Dichlorodiphenyltrichloroethane; Fluoride; Fluoride removal; Hazardous organics; Metalorganic frameworks (MOFs); MIL-53(al); Synthesised; Adsorption | English | 2022 | 2022-03-01 | 10.1016/j.cej.2021.133415 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Removal of benzonitrile and carbazole from model green-diesel derived from microalgae using metal-organic frameworks with protonated amines | The utilization of microalgae-derived fuel is very important for our sustainability. Here, adsorptive denitrogenation of model green-diesel (with considerable nitrogen-containing compounds, NCCs) was investigated to check the feasibility of adsorptive purification of fuel, derived from microalgae that is composed of NCCs. A highly porous MIL-101(Cr) (named M101) metal-organic framework was firstly modified to introduce protonated amino groups on both the linker and metallic sites of the MOF. The functionalized MOFs including P-M101-NH2-ED (P and ED mean 'protonated' and ethylenediamine, respectively), M101-NH2-ED, and M101-NH2 were applied (together with pristine M101 and a conventional activated carbon) in the adsorptive removal of N- containing compounds like benzonitrile (BENZ) and carbazole (CARB) from model green-diesel. The prepared P-M101-NH2-ED showed the most effective performances in the adsorption, compared with any other adsorbents known thus far. For instance, P-M101-NH2-ED adsorbed 15.6 and 3.6 times of BENZ and CARB, respectively, that of the activated carbon. The observed remarkable performances of P-M101-NH2-ED (Q(0) values for BENZ and CARB are 500 and 455 mg/g, respectively), although with lower porosity than other M101s, for BENZ and CARB adsorption could be explained mainly with hydrogen bonding and hydrogen bonding/cation-pi interactions, respectively. Moreover, P-M101-NH2-ED was recyclable in several cycles after simple ethanol washing. Therefore, P-M101-NH2-ED could be suggested as a plausible adsorbent to remove NCCs from green-diesel, based on remarkable performances and facile reusability. | 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; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 435 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 0.82 | 2025-06-25 | 12 | 13 | Adsorption; Denitrogenation; Green-diesel; Metal-organic frameworks; Microalgae | NITROGEN-CONTAINING COMPOUNDS; ULTRASOUND-ASSISTED SYNTHESIS; DOPED POROUS CARBONS; ADSORPTIVE DENITROGENATION; HYDROTHERMAL LIQUEFACTION; BIO-OIL; FUNCTIONAL-GROUPS; DYE REMOVAL; LIQUID FUEL; DESULFURIZATION | Adsorption; Denitrogenation; Green-diesel; Metal-organic frameworks; Microalgae | Activated carbon; Adsorption; Amines; Diesel engines; Hydrogen; Hydrogen bonds; Metals; Microorganisms; Organometallics; Polycyclic aromatic hydrocarbons; Protonation; Reusability; Adsorptive denitrogenation; Adsorptive purification; Amino group; Benzonitriles; Denitrogenation; Green diesels; Metalorganic frameworks (MOFs); Performance; Protonated; Protonated amine; Microalgae | English | 2022 | 2022-05-01 | 10.1016/j.cej.2022.134910 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Selective sequestration of perfluorinated compounds using polyaniline decorated activated biochar | Poly- and perfluorinated compounds (PFCs) in wastewater could induce the poisonous effects to the living beings throughout the world. In this present investigation, polyaniline (PANI) decorated activated biochar (AB) hybrid composite (AB@x%PANI, x = 0%, 25%, 50%, 75%, and 100% of PANI) was fabricated for PFCs adsorption via in situ chemical oxidation and co-precipitation with calcination. The physical and chemical properties of AB@x% PANI before and after adsorption were characterized by FTIR, PXRD, XPS, FE-SEM with EDX, HR-TEM, 13C NMR, and TGA analysis. Batch experiments for the effect of contact time, initial PFCs concentration, solution pH, and co-existing cations were conducted for the maximum adsorption capacity of as-synthesized adsorbents. The AB@75%PANI hybrid composite exhibited higher adsorption capacity for the removal of perfluorooctanoic, perfluorooctanesulfonic, and perfluorohexanesulfonic acids than powdered activated carbon, AB, PANI, AB@25%PANI, and AB@50%PANI. The adsorption isotherm and kinetic results demonstrated that the adsorption system using AB@75%PANI hybrid composite followed pseudo-second-order and Langmuir isotherm models. The PFCs adsorption by AB@75%PANI was mainly governed by various interaction forces such as hydrogen bonding, electrostatic attraction, hydrophobic interaction, and surface complexation in the presence of co-existing cations. These findings shed light on how to selectively eliminate PFCs from wastewater. | Yea, Yeonji; Kim, Gyuri; Wang, Dengjun; Kim, Sewoon; Yoon, Yeomin; Elanchezhiyan, S.

| ○ | ○ | Article | Synergistic conversion of CO2 into C1 and C2 gases using hybrid in-doped TiO2 and g-C3N4 photocatalysts | Achieving high-efficiency photocatalytic conversion of CO2 into value-added chemicals remains a challenge. This study synthesizes In-doped TiO2 and g-C3N4 composites (In-TiO2/g-C3N4) via a facile and reliable method. The as-synthesized In-TiO2/g-C3N4 produces CO, CH4, and C2H4 under UV, and CO and CH4 under visible light from gaseous CO2 and H2O vapor. A prolonged photocatalysis results in the continuous production of the same set of carbonaceous compounds over 30 h, with a photonic yield of similar to 40%. The yield of C2H4 with In-TiO2/g-C3N4 is similar to 11-times greater than the sum of In-TiO2 and g-C3N4. The CO2 adsorption isotherms show that In-TiO2 acts as a CO2 adsorbent and photocatalyst whereas g-C3N4 mainly works as a photocatalyst. In-situ FTIR study reveals the formation of CH4 and C2H4 on In-TiO2/g-C3N4. Time-resolved photoluminescence indicate that In-doping facilitates charge transfer and a strongly coupled g-C3N4 induces cascaded charge transfer. This leads to inhibited charge recombination and long-lived charge carriers. | Park, Jiyeon; Liu, Hao; Piao, Guangxia; Kang, Unseock; Jeong, Hye Won; Janaky, Csaba; Park, Hyunwoong | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Univ Szeged, Dept Phys Chem & Mat Sci, H-6720 Szeged, Hungary | Jeong, Hye Won/ABB-1797-2021; Janaky, Csaba/L-6467-2013; Park, Hyunwoong/A-1247-2012 | 57218367393; 58607766700; 57193277010; 55682720300; 55696273000; 8604561000; 7601565583 | h.jeong@chem.u-szeged.hu;hwp@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 437 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2022 | 15.1 | 3.2 | 2.2 | 2025-06-25 | 34 | 36 | Solar fuels; Artificial photosynthesis; Hydrocarbons; Charge transfers | CARBON-DIOXIDE; ARTIFICIAL PHOTOSYNTHESIS; REDUCTION; WATER; NANOPARTICLES; COPPER; OXIDE; ADSORPTION; NANOTUBES; OXIDATION | Artificial photosynthesis; Charge transfers; Hydrocarbons; Solar fuels | Artificial photosynthesis; Carbon dioxide; Indium compounds; Photocatalytic activity; Titanium dioxide; Artificial photosynthesis; CH 4; Facile method; Higher efficiency; Photo-catalytic; Reliable methods; Solar fuels; Synergistic conversion; Synthesised; Value-added chemicals; Charge transfer | English | 2022 | 2022-06-01 | 10.1016/j.cej.2022.135388 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
