| ○ | ○ | Article | Construction of a gelatin aerogel catalyst functionalized with LaCoO3 and g-C3N5 for efficient ciprofloxacin degradation via adsorption and peroxymonosulfate activation | Three-dimensional porous gelatin-based aerogels functionalized with LaCoO3 and nitrogen-rich graphitic carbon nitride (g-C3N5) were successfully fabricated via a freeze-drying approach. Herein, the gelatin-based aerogels served as excellent adsorbents and catalysts activating peroxymonosulfate (PMS) to efficiently degrade ciprofloxacin (CIP) from aqueous solutions. In comparison to the pristine gelatin aerogel (GA), the optimized functionalized aerogel (GA-LCCN-1.5) demonstrated a 17.0% superior CIP adsorption performance. Remarkably, GA-LCCN-1.5 exhibited 95.7% removal efficiency for CIP, attributed to the effective generation of (OH)-O-center dot, SO4 center dot-, and O-1(2) via PMS activation. In addition, high degradation efficiencies over 84.1% were maintained throughout a broad pH range of 3-9. Notably, GA-LCCN-1.5 demonstrated outstanding stability and reusability, with 93.2% CIP removal efficiency even after five reuse cycles indicating significant promise in real applications. Radical quenching and electron spin resonance (ESR) analysis suggest that CIP degradation was dominated by radical and non-radical routes through GA-LCCN-1.5 catalyzed PMS decomposition. Besides, the plausible CIP degradation mechanisms were systemically analyzed and proposed. The toxicities of CIP and the intermediate byproducts were evaluated and reported. The findings of this study and insights demonstrate a facile construction of a biopolymer-based aerogel catalyst for synergistic and efficient PMS activation for the removal of antibiotics in water. | Yea, Yeonji; Cha, Byungjun; Njaramba, Lewis Kamande; Kim, Sewoon; Choi, Jong Uk; Yoon, Yeomin; Park, Chang Min | Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ Iowa, Dept Civil & Environm Engn, Iowa City, IA 52242 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; Kamande, Lewis/JLL-5435-2023 | 57217304205; 57337280900; 57223183206; 57201422323; 57205217094; 7402126688; 57209588953 | sewoon-kim@uiowa.edu;yoony@cec.sc.edu;cmpark@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 495 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 1.38 | 2025-05-07 | 5 | 5 | Gelatin aerogel; Peroxymonosulfate; LaCoO3; g-C3N5; Ciprofloxacin | CARBON; PERFORMANCE; OXIDATION; ATRAZINE; OXYGEN | Ciprofloxacin; g-C<sub>3</sub>N<sub>5</sub>; Gelatin aerogel; LaCoO<sub>3</sub>; Peroxymonosulfate | Antibiotics; Catalysts; Chemical activation; Degradation; Efficiency; Electron spin resonance spectroscopy; Electrospinning; Lanthanum compounds; Magnetic moments; Reusability; Ciprofloxacin; Freeze drying; Functionalized; G-C3N5; Gelatin aerogel; Graphitic carbon nitrides; Peroxymonosulfate; Peroxymonosulfate activations; Removal efficiencies; ]+ catalyst; Aerogels | English | 2024 | 2024-09-01 | 10.1016/j.cej.2024.153106 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Continuous and self-charging electricity generator based on saltwater | In the field of energy harvesting and storage techniques, extensive efforts have been made to utilize abundant seawater on earth as an eco-friendly energy source. However, seawater-based energy harvesting methods are sensitive to environmental conditions, causing problems in sustainable energy production. Meanwhile, similar to common batteries, seawater-based batteries require external energy sources for charging and recharging. Therefore, developing seawater-based electricity devices that can produce energy continuously irrespective of environmental conditions and without external energy sources remains a great challenge. Herein, we developed a saltwater-based electricity generator (SWEG) using carbon nanotube and graphene oxide as electrodes, which can produce electricity sustainably and self-recharge without the need for any external energy sources after discharging the stored energy. The proposed SWEG generates a stable open-circuit voltage of similar to 300 mV. After being fully discharged at a high current density (0.5 mu A cm(-2)), the voltage can be recovered in 2 h. At moderate discharge current density (0.1 mu A cm(-2)), considerable voltage is maintained for 24 h. This continuous energy generation was aroused from the ion-redistribution between the surface of electrodes and the electrolyte of salt water. Our results demonstrate the feasibility of self-charging and continuous electricity generation without the constraint of atmospheric conditions. | Ha, Hyunho; Jang, Yunseon; Sung, Joohwan; Lee, Jiyeon; So, Hye-Mi; Lee, Jin Young; Lee, Hye Min; Jeong, Soo-Hwan; Hyun, Seungmin | Korea Inst Machinery & Mat KIMM, Dept Nano Devices & Displays, 156 Gajeongbuk Ro, Daejeon 34103, South Korea; Kyungpook Natl Univ, Dept Chem Engn, 80 Daehak Ro, Daegu 41566, South Korea; LG Energy Solut, Adv Automot Battery Dev Ctr, Adv Automot Battery Div, 188 Munji Ro, Daejeon 34122, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, 80 Daehak Ro, Daegu 41566, South Korea; Univ Sci & Technol UST, Dept Nano Devices & Displays, Daejeon 34113, South Korea | Jang, Yunseon/IXW-8517-2023; , SooHwanJeong/JOJ-6732-2023 | 57220616968; 57851212600; 58977234900; 58853009300; 7102300040; 57080044000; 58318585700; 7402425359; 55566541700 | shjeong@knu.ac.kr;hyun@kimm.re.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 488 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 0 | 2025-05-07 | 0 | 0 | Saltwater -based electricity generator; Energy harvesting; Electricity generator | POWER-GENERATION; GRAPHENE OXIDE; WAVE ENERGY; REDISTRIBUTION; DROPLET | Electricity generator; Energy harvesting; Saltwater-based electricity generator | Carbon nanotubes; Charging (batteries); Electric discharges; Electrodes; Electrolytes; Graphene; Open circuit voltage; Power generation; Seawater; Secondary batteries; Eco-friendly; Electricity generators; Energy source; Environmental conditions; External energy sources; Harvesting methods; Saltwater-based electricity generator; Storage technique; Sustainable energy; Energy harvesting | English | 2024 | 2024-05-15 | 10.1016/j.cej.2024.151054 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Controlling the compositional matrix of pyrogenic products using carbon dioxide in the pyrolysis of agricultural plastic waste | Plastics are extensively employed in agriculture, generating an enormous volume of plastic waste. This study investigated the pyrolysis of silage film waste (SFW) to enable its conversion into energy/value-added chemicals. CO2 was chosen as the reactive medium to provide green pyrolysis. Nevertheless, the results showed that most of the carbon in the SFW was assigned to wax-like oil formed by thermal cracking. It was presumed that the reactivity of CO2 was effective only under certain optimal temperature conditions. To this end, the test setup was modified to increase the residence time of the reactants (CO2 and volatiles from SFW). With respect to inert gas conditions, syngas formation was observed under CO2 conditions. The enhanced formation of syngas was realised by the simultaneous reduction of CO2 into CO and the oxidation of volatiles into CO. CO2 also enhances the thermal cracking of volatiles, leading to enhanced formation of C-2-hydrocarbons. These features provide an effective means of decreasing the aromaticity of oil from SFW pyrolysis. The simultaneous reduction of CO2 into CO and oxidation of volatiles into CO block the mechanistic pathway to form polycyclic aromatic hydrocarbons. CO enhancement by CO2 offers an effective means for abating the fate of toxic chemicals. | Lee, Dong -Jun; Park, Jonghyun; Kim, Jee Young; Jung, Sungyup; Choi, Ye-Bin; Park, Soyeon; Seo, Siyoung; Tsang, Yiu Fai; 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; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, 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 | ; Kim, Jee Young/LKL-4818-2024; Tsang, Yiu/AAJ-2524-2020; Jung, Sungyup/ABE-1493-2021; Kwon, Eilhann/AGY-3339-2022 | 57191538179; 58544742000; 57191420766; 55073290800; 58758862500; 58758785600; 57219439927; 22954605700; 9240622100 | ek2148@hanyang.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 482 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 2.48 | 2025-05-07 | 9 | 10 | Waste valorisation; Waste-to-energy; Agricultural plastic waste; Pyrolysis; Polycyclic aromatic hydrocarbon (PAH) | POLYCYCLIC AROMATIC-HYDROCARBONS; TECHNOLOGIES; POLYETHYLENE; FILM; OIL | Agricultural plastic waste; Polycyclic aromatic hydrocarbon (PAH); Pyrolysis; Waste valorisation; Waste-to-energy | English | 2024 | 2024-02-15 | 10.1016/j.cej.2024.148968 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Development of a circulating fluidized bed for a 100 kg/day waste plastic pyrolysis-combustion system | The aim of this study was to develop a 100 kg/day plastic waste pyrolysis-combustion circulating fluidized bed (CFB) system. The CFB was designed to provide heat from the combustor (semi-riser type) to the pyrolyzer (bubbling fluidized bed (BFB)) through heat carriers in high efficiency. A 100 kg/day scale system, including an oil condensation facility, was constructed and operated continuously for 34.5 hrs. Pelletized polypropylene was supplied to the pyrolyzer as plastic waste. The temperature in the pyrolyzer and plastic feeding rate were experimental variables. The weight percentage of low (C1-C12) 1 - C 12 ) and middle (C13-C22) 13 - C 22 ) carbon number components of the produced oil in CFB operated at 512-551 degrees C was 65.3 and 23.2 %, respectively. These were significantly higher than 34.6 and 28.4 % of the BFBs with similar temperatures previously, implying that the heat transfer in the CFB was more intense than that in the BFB. Compared to the BFB, only subtle differences in the pyrolysis gas yield was observed for CFB, which signified that the gas mixing between two reactors was minimized during the operation. Although no blockage was found in the CFB, clogging of condensers and pipelines occurred during low-temperature operation owing to the relatively low pour point of the product oil. The results in this study provide detailed and practical information on the temperature, pressure, product gas, oil, and clogging issues to better understand plastic pyrolysis in CFB. | Kim, Daewook; Yoon, Young Min; Jang, Jae Jun; Choi, Yujin; Won, Yooseob; Ryu, Ho-Jung; Nam, Hyungseok; Lee, Doyeon; Choi, Jeong-Hoo; Hwang, Byungwook | Korea Inst Energy Res, 152 Gajeong Ro, Daejeon 34129, South Korea; Kyungpook Natl Univ, 80 Daehak Ro, Daegu 41566, South Korea; Sungkyunkwan Univ, 2066 Seobu Ro, Suwon 16419, South Korea; Hanbat Natl Univ, 125 Donseodae Ro, Daejeon 34158, South Korea; Konkuk Univ, 120 Neungdong Ro, Seoul 05029, South Korea | Yoon, Youngmin/MSZ-2536-2025; Ryu, Ho-Jung/AAV-3451-2020 | 55569361600; 58701048400; 57553717800; 57734617200; 57212454920; 7202277238; 57190418228; 55881252900; 7501392397; 44461423600 | namhs219@knu.ac.kr;hbw@kier.re.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 499 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 0.28 | 2025-05-07 | 2 | 2 | Waste plastic; Pyrolysis; Combustion; Circulating fluidized bed; Polypropylene | PRESSURE-DROP; RECOVERY; FLOW; POLYPROPYLENE; POLYETHYLENE; POLYOLEFINS | Circulating fluidized bed; Combustion; Polypropylene; Pyrolysis; Waste plastic | Fluidized bed combustors; Fluidized beds; Pyrolysis; Waste incineration; Bubbling fluidized bed; Circulating fluidized bed; Combustion systems; Fluidized bed system; Plastic pyrolysis; Plastics waste; Pyrolysis combustions; Pyrolyze; Waste plastic; Waste pyrolysis; Fluidized bed combustion | English | 2024 | 2024-11-01 | 10.1016/j.cej.2024.156257 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Direct conversion of cottonseeds into biodiesel | Biodiesel production is recommended to achieve sustainable energy practices because of its high compatibility with petrol-derived diesel. Conventionally, acid- or alkaline-catalyzed transesterification of refined oil is used for biodiesel production, however, oil extraction and refinement from oil-bearing biomass leads to losses. Therefore, we propose a novel approach that directly converts cottonseeds into biodiesel. Biodiesel yield from non-catalytic transesterification of cottonseed oil at 360 degrees C within 1 min was high at 96.3 wt%, surpassing the yield (80.6 wt%) from alkali-catalyzed transesterification at 60 degrees C for 60 min. Biodiesel yield from non-catalytic transesterification of cottonseed at 360 degrees C within 1 min was 22.7 wt%. For cottonseed oil content (20.9 wt%), overall biodiesel yield from cottonseed was 108.7 wt%, implying that oil extraction using conventional methods was incomplete. Therefore, directly converting cottonseed into biodiesel through non-catalytic transesterification is a viable and efficient alternative for biodiesel production. | Park, Gyeongnam; Choi, Dongho; Kim, Jee Young; Jung, Sungyup; Tsang, Yiu Fai; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Hong Kong 999077, New Territories, Peoples R China; Educ Univ Hong Kong, State Key Lab Marine Pollut, Hong Kong 999077, New Territories, Peoples R China | Kim, Jee Young/LKL-4818-2024; Choi, Dongho/LTY-8225-2024; Tsang, Yiu/AAJ-2524-2020; Jung, Sungyup/GZG-6207-2022; Kwon, Eilhann/AGY-3339-2022 | 59141730800; 57200013497; 57191420766; 55073290800; 22954605700; 9240622100 | ek2148@hanyang.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 493 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 1.1 | 2025-05-07 | 7 | 7 | Circular economy; Biomass valorization; Biodiesel; Non-catalytic transesterification; Cottonseeds | ENERGY; WASTE; OIL; TRANSESTERIFICATION; INFRASTRUCTURE; GOSSYPOL | Biodiesel; Biomass valorization; Circular economy; Cottonseeds; Non-catalytic transesterification | Catalysis; Cottonseed oil; Extraction; Oilseeds; Transesterification; Alkalines; Biodiesel production; Biomass valorizations; Circular economy; Cottonseed; Direct conversion; Non-catalytic transesterification; Oil extraction; Sustainable energy; Transesterifications; Biodiesel | English | 2024 | 2024-08-01 | 10.1016/j.cej.2024.152491 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Dynamically crosslinked poly(vinyl alcohol)/borax strain sensors for organ motion monitoring | Wearable electronic sensing devices can detect various physiological responses and subtle changes in the skin in real time for the early detection and treatment of potential health problems or diseases. Among them, flexible hydrogel-based sensors are attracting much attention because they can monitor human movements and physiological signals. However, developing hydrogel-based sensors with rapid self-healing, self-adhesion, excellent conductivity and sensitivity characteristics remains a challenge. In this study, a hydrogel with a dynamic reversible network structure was developed using poly(vinyl alcohol) (PVA), hyaluronic acid (HA), borax, and tannic acid (TA). Multiple hydrogen bonds resulting from abundant hydroxyl groups in the hydrogel composed of borax, PVA, and TA improved the self-healing ability of the hydrogel, and the conductivity of this system (similar to 0.62 S/m) was improved upon immersion in NaCl. The optimum hydrogel exhibited excellent elasticity (similar to 941 %), biocompatibility, and demonstrated adhesion to porcine skin (dry: 5.3 kPa; wet: 2 kPa) without external stimulation in air and underwater environments. In addition, the fabricated hydrogels exhibited excellent sensitivity (similar to 300 % strain, gauge factor (GF) = 2.86; 300-900 % strain, GF = 4.95), allowing them to detect and distinguish various large and small human movements. Hydrogels that exhibited stable electrical signals even after 500 cycles were obtained, and the PBHT-N hydrogels were implanted into rabbit hearts to verify their applicability as strain sensors for effective real-time heart rate monitoring during rapid body movement. | Nam, Ji Woo; Moon, Chang-Hwan; Kim, Dae-Hyun; Kim, Min Hee; Park, Won Ho | Chungnam Natl Univ, Dept Organ Mat Engn, Daejeon 34134, South Korea; Chungnam Natl Univ, Coll Vet Med, Dept Vet Surg, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Text Engn, Sangju 37224, South Korea | 59168769700; 57211242244; 57215570370; 57188948163; 57211114215 | mhkim88@knu.ac.kr;parkwh@cnu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 498 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 0.83 | 2025-05-07 | 7 | 7 | Poly(vinyl alcohol); Conductive hydrogel; Self-healing; Strain sensor; Human motion detection; Implantable heart monitoring | HYDROGEL | Conductive hydrogel; Human motion detection; Implantable heart monitoring; Poly(vinyl alcohol); Self-healing; Strain sensor | Cardiology; Electrotherapeutics; Medical problems; mHealth; Physiological models; Conductive hydrogel; Heart monitoring; Human motion detection; Implantable heart monitoring; Poly (vinyl alcohol) (PVA); Poly(vinyl alcohol); Poly(vinyl alcohol) (PVA); Self-healing; Strain sensors; Heart | English | 2024 | 2024-10-15 | 10.1016/j.cej.2024.155748 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effective aerobic oxidative denitrogenation of model fuel with metal-free porous carbon derived from phytic acid-loaded polyaniline | Aerobic oxidative denitrogenation (ODN) of a model fuel was first done with metal-free P and O co-doped carbon catalysts. The catalysts, phytic acid (PA)-loaded polyaniline-derived carbons (PPDCs), were firstly prepared by high-temperature pyrolysis of polyaniline with phytic acid (as P/O sources). One material, PPDC-2 showed a conversion of 95 % and 86 % for indole (IND) and quinoline (500 ppm each), respectively, at 100 degrees C, with O-2 as an oxidant. A very small activation energy of 26.6 kJ mol(-1) was observed in the IND oxidation. Radical trapping experiments and electron spin resonance spectroscopy analyses supported the formation of superoxide anion radicals (O-2(-)) from the fed O-2, which was responsible for the IND oxidation. A plausible reaction mechanism was proposed by analyzing the experimental results and DFT calculations on charge separations on carbons. Defect sites also could play an important role in the activation of O-2 since PPDC-2 showed higher defect sites compared to the non-doped carbon. PPDC-2 was also found to be recyclable for the ODN, by simple acetone soaking, without a considerable loss in performance. | Ahmed, Imteaz; 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 | 55377179600; 6701659467 | sung@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 479 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 1.52 | 2025-04-16 | 7 | 7 | Fuel purification; Mechanism; Metal-free catalyst; Oxidative denitrogenation; O/P co-doped carbon | REDUCED GRAPHENE OXIDE; FREE CATALYST; DOPED GRAPHENE; DIESEL FUEL; NITROGEN; OIL; DESULFURIZATION; ADSORPTION; SULFUR; BORON | Fuel purification; Mechanism; Metal-free catalyst; O/P co-doped carbon; Oxidative denitrogenation | Acetone; Activation energy; Carbon; Defects; Electron spin resonance spectroscopy; Magnetic moments; Porous materials; Co-doped; Derived carbons; Doped carbons; Indole oxidation; Metal free; Metal-free catalysts; Model fuels; O/P co-doped carbon; Oxidative denitrogenation; Phytic acids; Catalysts | English | 2024 | 2024-01-01 | 10.1016/j.cej.2023.147679 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Electrocatalytic conversion of ethylene to ethylene oxide mediated by halide oxidation: Chloride vs. Bromide vs. Iodide | Ethylene oxide (EO) is among the most extensively used chemicals and is conventionally produced via the thermochemical oxidation of ethylene. This study demonstrates that a Pt-doped RuO2 and TiO2 composite (PtRuO2/TiO2) electrocatalyst drives ethylene oxidation to EO in the presence of reactive chlorine and bromine species in aqueous chloride and bromide solutions at Faradaic efficiencies (FEs) of -100 % and -90 %, respectively. Despite a lower FE, the bromine production is more feasible than the chlorine production and the as-formed bromine species remains stable for postreaction with ethylene. The iodine species exhibits a low reactivity toward ethylene. The activity of Pt-RuO2/TiO2 is substantially higher than that of other catalysts. Membraned and membraneless flow electrolyzers with a Pt-RuO2/TiO2 anode for ethylene oxidation and a Pt/C cathode for oxygen reduction are demonstrated at J = 500 mA cm- 2. Technoeconomic analysis reveals reduction in the production cost of EO by 10 % with the membraneless electrolyzer. | Liang, Nan-Nan; Choi, Wonjung; Han, Dong Suk; Park, Hyunwoong | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Qatar Univ, Ctr Adv Mat, Res Complex H10, Doha, Qatar | Han, Dong SuK/AAX-9333-2021; Park, Hyunwoong/A-1247-2012 | 57800564000; 56419210400; 58809106000; 7601565583 | hwp@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 494 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 1.38 | 2025-05-07 | 9 | 9 | Electrocatalysis; Green synthesis; Partial oxidation; Halogen species; Ethylene | ELECTROCHEMICAL OXIDATION; MOLECULAR-HYDROGEN; WATER; REMEDIATION; ANODES; BIVO4 | Electrocatalysis; Ethylene; Green synthesis; Halogen species; Partial oxidation | Chlorine compounds; Electrocatalysis; Electrocatalysts; Electrodes; Electrolysis; Electrolytic reduction; Oxidation; Platinum compounds; Ruthenium compounds; Titanium dioxide; Electrocatalytic; Electrolyzers; Ethylene oxidation; Ethylene oxides; Faradaic efficiencies; Green synthesis; Halogen species; Membraneless; Partial oxidations; Thermochemicals; Ethylene | English | 2024 | 2024-08-15 | 10.1016/j.cej.2024.153042 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhancing sustainability: Upcycled membrane distillation for water and nutrient recovery from anaerobic membrane bioreactor effluent | Addressing the critical issue of recycling end-of-life membranes, this study focuses on the meticulous process of removing contaminants and rejuvenating deteriorated polyvinylidene difluoride (PVDF) membranes for secondary applications. We unveil a successful upcycling approach wherein these membranes are effectively cleaned and recoated, transforming them for utilization in the membrane distillation (MD) process. Citric acid proved to be the most effective cleaning agent, efficiently removing foulants and restoring the membranes' original color, surface composition, and hydrophobicity. Surface analyses confirmed the removal of metallic foulants, with significant improvements in pore structure and contact angle, indicating effective property restoration. Further analyses revealed that coating PVDF membranes with 5 % carnauba wax and 0.1 % polysulfone resulted in the most hydrophobic surface, characterized by increased prominence of carnauba wax peaks, decreased PVDF peaks, and reduced O 1s peak, enhancing hydrophobicity. Optimal hydrophobicity suitable for MD was achieved with minimal polysulfone addition, producing near-superhydrophobic characteristics with a water contact angle of similar to 150 degrees and peak surface roughness of 287 nm. Higher polysulfone content reduced hydrophobicity and surface roughness. The upcycled membrane significantly decreased the crossover of ionic species to the permeate with minimal reduction in water flux, demonstrating superior retention of nutrients as eco-friendly fertilizers from anaerobic digestate. Additionally, acidifying the digestate to pH 5 minimizes NH3 emissions, and MD treatment at 70 degrees C inactivates pathogens, making the process suitable for water and nutrient recovery, thereby supporting zero liquid discharge and the transition to a circular economy. | Park, Hyung-June; Park, Hyeona; Kim, Jinwoo; Lee, Kwonki; Naddeo, Vincenzo; Choo, Kwang-Ho | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Inst Water Ind, 80 Daehak Ro, Daegu 41566, South Korea; Synopex, 54-42 Dongtanhana 1-gil, Hwaseong 18423, South Korea; Univ Salerno, Dept Civil Engn, Sanit Environm Engn Div, Via Giovanni Paolo II, I-84084 Fisciano, Italy; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | Naddeo, Vincenzo/C-4057-2008; Choo, Kwang-Ho/A-3456-2016 | 57213039678; 57213039681; 57901150400; 59304659400; 57225215311; 7102083272 | chookh@knu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 498 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 0 | 2025-05-07 | 0 | 0 | Circular economy; Membrane distillation; Membrane upcycling; Natural wax; Nutrient recovery | POLYSULFONE MEMBRANES; FOULING PREVENTION; NANOPARTICLES; MECHANISMS; STRATEGY | Circular economy; Membrane distillation; Membrane upcycling; Natural wax; Nutrient recovery | Effluents; Surface roughness; Carnauba wax; Circular economy; Foulants; Membrane distillation; Membrane upcycling; Natural waxes; Nutrient recovery; Polysulphone; Polyvinylidene difluoride; Water recovery; Nafion membranes | English | 2024 | 2024-10-15 | 10.1016/j.cej.2024.155267 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Exploring novel quorum quenching strain: Enhanced disrupting autoinducer-2 bacterial communication to combat biofouling in membrane bioreactor for wastewater treatment | Prior investigations concerning quorum quenching (QQ), which hinders quorum sensing (QS) in microbial communication, concentrated predominantly on N-acylhomoserine lactones (AHLs), which are communicated merely by gram-negative bacteria. However, to combat biofouling more effectively, particularly biofilm-related issues, it is important to explore the inhibition of autoinducer-2 (AI-2), a universal signal (interspecies communication) employed by both gram-negative and gram-positive bacteria. This study aimed to isolate and identify novel strains capable of more effectively inhibiting AI-2 signaling for use in engineering fields. The results revealed that the newly isolated strain Pantoea sp. PL-1 demonstrated remarkable efficacy in attenuating AI-2 signals, leading to a substantial reduction in the AI-2 precursor (S)-4,5-dihydroxy-2,3-pentandione (DPD) in both its pellet (with a DPD removal efficiency of 90.8 % after 180 min, with a rate constant of k = 0.8 h-1) and supernatant form (66.9 %, k = 0.37 h-1). Interestingly, the findings indicate that strain DKY-1, a strain previously reported to exhibit AI-2 QQ activity, only reduced DPD levels in its supernatant form (extracellular activity), while both the pellet and the supernatant of strain PL-1 demonstrated AI-2 QQ activity, indicating both intracellular and extracellular QQ activity. Adding the PL-1 supernatant to co-cultures of two AI-2 QS strains, E. coli K12 and P. mirabilis, successfully reduced DPD by 40 % and 70 %, respectively, without impeding their growth. Additionally, when assessing the impact of PL-1 to minimize membrane biofouling in a membrane bioreactor, it demonstrated superior performance compared to the DKY-1 strain, with a 40 % improvement. The AI-2 QQ compound of PL-1 has been identified as highly hydrophilic and low-molecular-weight, and its exact properties have not yet been fully elucidated. Therefore, uncovering its identity may be an important goal for future research. | Park, Hyeyeon; Jang, Jun-U; Park, Jeongmi; Park, Hyeona; Choo, Kwang-Ho; Jeon, Jongho; Yeo, Hyeonuk; Lee, Chung-Hak; Lee, Kibaek | Chonnam Natl Univ, Dept Biotechnol & Bioengn, Gwangju 61186, South Korea; Kyungpook Natl Univ, Adv Inst Water Ind, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem Educ, Daegu 41566, South Korea; Seoul Natl Univ, Sch Chem & Biol Engn, Seoul 08826, South Korea | Choo, Kwang-Ho/A-3456-2016; yeo, hyeonuk/G-7890-2017; Yeo, Hyeonuk/AHE-0397-2022 | 58116081800; 58116081700; 58116037400; 57213039681; 7102083272; 35082028100; 55324816500; 7410142508; 55845961700 | kibaek@jnu.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 486 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 0.83 | 2025-05-07 | 5 | 4 | Autoinducer-2; Quorum sensing; Quorum quenching; Biofilm; Biofouling; Membrane bioreactor | BIOFILM FORMATION; RESISTANCE; TECHNOLOGY; GROWTH; MBRS | Autoinducer-2; Biofilm; Biofouling; Membrane bioreactor; Quorum quenching; Quorum sensing | Bioconversion; Biofilms; Biofouling; Escherichia coli; Pelletizing; Quenching; Rate constants; Wastewater treatment; Autoinducer-2; Bacterial communications; Gram-negative bacteria; Gram-positive bacterium; Membrane bioreactor; Microbial communications; N-acylhomoserine lactones; Quorum quenching; Quorum-sensing; Supernatants; Bioreactors | English | 2024 | 2024-04-15 | 10.1016/j.cej.2024.150173 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Flashlight treatment for instantaneous structuring of dense MXene film into porous MXene/TiO2 nanocomposite for lithium-ion battery anodes | MXenes, the two-dimensional metal carbides and nitrides, have been considered a new class of electrode materials with their noticeable performance in various energy storage systems. Furthermore, the unique property and morphology allow MXenes to be assembled into freestanding films, which can be applied in energy storage devices with lightweight and high energy density. However, their tendency to restack and aggregate remains a challenge to enhance the electrochemical performance of MXenes. In this study, we propose a facile method to fabricate a porous MXene-TiO2 freestanding anode with the help of a flashlight. Simply heating the MXene films with a flashlight in milliseconds increases the interlayer spacing of the MXenes and simultaneously forms TiO2 on the MXene surface. Along with the widened interlayer and formation of TiO2, improved wettability, easy electrolyte penetration, and reduced electrode resistance were achieved. As a result, this freestanding anode exhibits nearly 50 times higher Li+ storage capacity (148 mAh/g) than pristine MXene film (3 mAh/g) at 0.05 A/g and excellent cycle stability up to 1500 cycles without degradation. © 2024 Elsevier B.V. | Hong, Jeongsoo; Paeng, Changung; Park, Seongmin; In, Insik; Lee, Huijin; Velhal, Ninad B.; Yun, Tae Ho; Jo, Changshin; Yim, Changyong | Department of Chemical Engineering, Pohang University of Science and Technology (POSTECH), 77 Cheongam-Ro, Nam-Gu, Gyeongbuk, Pohang, 37673, South Korea; Department of Energy Materials & Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Gyeongbuk, Sangju, 37224, South Korea; Department of IT-Energy Convergence (BK21 Four), Korea National University of Transportation (KNUT), 50 Daehak-Ro, Chungbuk, Chungju, 27469, South Korea, Department of Polymer Science and Engineering, Chemical Industry Institute, Korea National University of Transportation (KNUT), 50 Daehak-Ro, Chungbuk, Chungju, 27469, South Korea; Department of IT-Energy Convergence (BK21 Four), Korea National University of Transportation (KNUT), 50 Daehak-Ro, Chungbuk, Chungju, 27469, South Korea, Department of Polymer Science and Engineering, Chemical Industry Institute, Korea National University of Transportation (KNUT), 50 Daehak-Ro, Chungbuk, Chungju, 27469, South Korea; Department of Energy Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-daero, Gyeongbuk, Sangju, 37224, South Korea; Department of Energy Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-daero, Gyeongbuk, Sangju, 37224, South Korea; Department of Precision Mechanical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-daero, Gyeongbuk, Sangju, 37224, South Korea; Department of Chemical Engineering, Pohang University of Science and Technology (POSTECH), 77 Cheongam-Ro, Nam-Gu, Gyeongbuk, Pohang, 37673, South Korea, Graduate Institute of Ferrous and Eco Materials Technology (GIFT), Pohang University of Science and Technology (POSTECH), 77 Cheongam-Ro, Nam-Gu, Gyeongbuk, Pohang, 37673, South Korea; Department of Energy Materials & Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Gyeongbuk, Sangju, 37224, South Korea, Department of Energy Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-daero, Gyeongbuk, Sangju, 37224, South Korea, Department of Advanced Science and Technology Convergence, Kyungpook National University (KNU), 2559 Gyeongsang-daero, Gyeongsangbuk, Sangju, 37224, South Korea | 58514049400; 58161154100; 57210991898; 8509060200; 58895644700; 56116686900; 55383561400; 37112455900; 36877182000 | jochangshin@postech.ac.kr; | Chemical Engineering Journal | CHEM ENG J | 1385-8947 | 1873-3212 | 484 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 3.86 | 2025-05-07 | 16 | 3D porous structure; Anti-restacking; Flashlight; MXene; TiO<sub>2</sub> formation | English | Final | 2024 | 10.1016/j.cej.2024.149598 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Hydrogen production from fishing net waste for sustainable clean fuel: Techno-economic analysis and life cycle assessment | Fishing net waste (FNW) represents more than half of marine debris, posing a substantial challenge to marine ecosystems. Conventional disposal methods, such as landfills and incineration, contribute to environmental pollution and overlook valuable material recovery. To address this issue, an innovative process that converts FNWs into high -purity hydrogen (H2) through pyrolysis under CO2 conditions, integrated with a natural gas (NG) reforming process, was proposed. The resulting gas undergoes a water-gas shift (WGS) reaction with NGreforming syngas, amplifying H2 production yield. High -purity H2 is achieved through pressure swing adsorption (PSA). The high -temperature flue gas from pyrolysis oil combustion is utilized to generate electricity via the steam Rankine cycle (SRC) process. Furthermore, CO2 in the flue gas is liquefied and stored through a carbon capture and storage (CCS) process. Techno-economic evaluation and life -cycle assessment (LCA) were performed to scrutinize the efficiency and feasibility of the proposed process. This study first demonstrated that the CO2- based waste fishing net pyrolysis integrated H2 production process yielded 10.66 kmol h-1 of H2, providing a significant step toward sustainable H2 production. Second, 87.13 % of wasted energy was recovered through the thermal integrated energy optimization of the waste fishing net and NG reforming process, and an additional 539.1 kW of electricity was generated through the SRC process, demonstrating high energy efficiency. Finally, although the levelized cost of hydrogen (LCOH) was slightly greater than that of the steam methane reforming (SMR) process, LCA revealed a significantly low greenhouse gas (GHG) index. Therefore, the proposed process serves as an eco-friendly approach to increase hydrogen production yield, which is a clean raw material with no carbon emissions, concurrently addressing the recycling of FNWs. | Lee, Hyejeong; Im, Junhyeok; Cho, Hyungtae; Jung, Sungyup; Choi, Hyeseung; Choi, Dongho; Kim, Junghwan; Lee, Jaewon; Kwon, Eilhann E. | Korea Inst Ind Technol, Low Carbon Energy Grp, 55 Jongga Ro, Ulsan 44413, South Korea; Yonsei Univ, Dept Chem & Biomol Engn, 50 Yonsei Ro, Seoul 03722, South Korea; Hongik Univ, Dept Chem Engn, 94 Wausan Ro, Seoul 04066, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Hanyang Univ, Sch Int Studies, Seoul 04763, South Korea; Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea | ; Choi, Dongho/LTY-8225-2024; lee, jaewon/JEO-9073-2023; Kim, Junghwan/AAQ-9204-2021; Jung, Sungyup/ABE-1493-2021; Kwon, Eilhann/AGY-3339-2022; Cho, Hyungtae/JEO-8285-2023 | 57471133700; 58770576100; 55326115100; 55073290800; 59278021900; 57200013497; 56222925800; 57200543537; 9240622100 | j.lee@kitech.re.kr;ek2148@hanyang.ac.kr; | CHEMICAL ENGINEERING JOURNAL | CHEM ENG J | 1385-8947 | 1873-3212 | 481 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 13.2 | 3.0 | 3.31 | 2025-05-07 | 13 | 15 | Fishing net waste; Steam methane reforming; CO2 capture and storage; cleanH2; Sustainability; Greenhouse gas | GAS SHIFT REACTION; CO2 CAPTURE; POWER-PLANTS; OPTIMIZATION; PYROLYSIS; MEMBRANE; RECOVERY; DESIGN; STEAM; MEA | clean H<sub>2</sub>; CO<sub>2</sub> capture and storage; Fishing net waste; Greenhouse gas; Steam methane reforming; Sustainability | English | 2024 | 2024-02-01 | 10.1016/j.cej.2024.148741 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Industrial-scale blown active packaging film with essential oils: Properties, dual-functional performance, and box packaging application of instant noodles | This study aimed to develop a bio-based blown active packaging film containing the essential oils and chaff with dual insect-repellent and antimicrobial activities at industrial-scale. The mixture of Origanum vulgare and Tanacetum cinerariifolium (O1T3) was adsorbed on celite and fumed silica, and their insect-repellent activities were determined using a long cylinder trap. The immobilized O1T3 on celite (OTC) exhibited superior prolonged repellent efficacy for up to 14 days. Linear low-density polyethylene/chaff blown active films (LLCBF-OTCs) were then manufactured with three different percentages of the OTC using a blown twin-screw extruder. Their optical and mechanical properties were examined to determine the optimum OTC concentration. Among them, LLCBF-OTC0.5 exhibited the highest elongation at break and tensile strength, as well as similar opacity and color with LLCBF film. Finally, its antimicrobial and insect-repellent activities were evaluated using ISO22196 standard and the designed large chambers to control P. interpunctella and C. cautella larvae under a simulated field condition of instant noodles, respectively. Its ISO22196-based values of antimicrobial activity were 4.9 for Escherichia coli and 3.5 for Staphylococcus aureus. More importantly, the LLCBF-OTC0.5 showed 8.12- and 2.17fold greater insect-repellent activity than the control film against P. interpunctella and T. castaneum, respectively. Thus, LLCBF-OTC0.5 demonstrated excellent feasibility for its commercial use as an industrial-scale active box packaging film in the food industry. | Kim, Su-Hyeon; Kang, Si Eun; Kim, Young-Duk; Park, Mi-Kyung | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; DGIST, ICT Res Inst, Daegu 42988, South Korea; Kyungpook Natl Univ, Food & Bioind Inst, Daegu 41566, South Korea | Park, MK/GVU-0647-2022 | 57217051011; 58794797800; 55955831300; 7404491155 | parkmik@knu.ac.kr; | FOOD PACKAGING AND SHELF LIFE | FOOD PACKAGING SHELF | 2214-2894 | 43 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2024 | 10.6 | 3.0 | 1.18 | 2025-05-07 | 3 | 3 | Bio-based blown active film; Box packaging; Industrial -scale; Origanum vulgare; Tanacetum cinerariifolium; Instant noodles | ANTIMICROBIAL ACTIVITY; CHITOSAN; BASIL | Bio-based blown active film; Box packaging; Industrial-scale; Instant noodles; Origanum vulgare; Tanacetum cinerariifolium | English | 2024 | 2024-06 | 10.1016/j.fpsl.2024.101276 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
