| ○ | ○ | Article | Catalytic oxidation reactions for environmental remediation with transition metal nitride nanoparticles | Catalytic oxidation reactions, one of typical examples of environmental catalysis, can be effectively carried out with transition metal nitrides (TMNs) that are recently advanced much. TMNs are more advantageous compared to their counterpart, traditional metal oxides, due to their better electronic configuration, enhanced redox properties, lower operating temperatures, and resistance to sintering. They can be also used as a replacement for expensive noble metal catalysts. Considering their advantageous applications, a review about the preparation of the TMNs and their applications in oxidation catalysis is required. At the beginning of the review, the advantages of the TMNs over metal oxides were introduced. Next, the preparation methods of TMNs were discussed. Then, the application of TMNs in catalytic oxidation reactions, including oxidative desulfurization and denitrogenation of fuel, was discussed in detail. Finally, the contents were summarized and prospects were given for the future study of TMNs. | Ahmed, Imteaz; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea | Jhung, Sung/AAO-6683-2021 | 55377179600; 6701659467 | imteaz2004@gmail.com;sung@knu.ac.kr; | JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING | J ENVIRON CHEM ENG | 2213-2929 | 2213-3437 | 12 | 3 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 7.2 | 14.0 | 1.06 | 2025-05-07 | 8 | 8 | Environmental catalysis; Metal-nitrides; Oxidation; Nanoparticles; Transition metals | HYDROGEN EVOLUTION REACTION; MOLYBDENUM NITRIDE; TITANIUM NITRIDE; SELECTIVE OXIDATION; ORGANIC FRAMEWORKS; IRON NITRIDE; FACILE ROUTE; TUNGSTEN NITRIDE; HIGHLY EFFICIENT; RECENT PROGRESS | Environmental catalysis; Metal-nitrides; Nanoparticles; Oxidation; Transition metals | Catalysis; Catalysts; Metal nanoparticles; Nitrides; Precious metals; Refractory metal compounds; Sintering; Electronic configuration; Environmental catalysis; Environmental remediation; Low operating temperature; Metal nitrides; Metal-oxide; Nitride nanoparticles; Oxidation reactions; Redox property; Transition metal nitrides; Catalytic oxidation | English | 2024 | 2024-06 | 10.1016/j.jece.2024.112907 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Chromatin remodeling-driven autophagy activation induces cisplatin resistance in oral squamous cell carcinoma | It is still challenging to predict the efficacy of cisplatin-based therapy, particularly in relation to the activation of macroautophagy/autophagy in oral squamous cell carcinoma (OSCC). We studied the effect of selected chromatin remodeling genes on the cisplatin resistance and their interplay with autophagy in 3-dimensional tumor model and xenografts. We analyzed gene expression patterns in the cisplatin-sensitive UMSCC1, and a paired cisplatin-resistant UM-Cis cells. Many histone protein gene clusters involved in nucleosome assembly showed significant difference of expression. Gain- and loss-of-function analyses revealed an inverse correlation between cisplatin resistance and HIST1H3D expression, while a positive correlation was observed with HIST3H2A or HIST3H2B expression. In UM-Cis, HIST3H2A- and HIST3H2B-mediated chromatin remodeling upregulates autophagy status, which results in cisplatin resistance. Additionally, knockdown of HIST3H2A or HIST3H2B downregulated autophagy-activating genes via chromatin compaction of their promoter regions. MiTF, one of the key autophagy regulators upregulated in UM-Cis, negatively regulated transcription of HIST1H3D, suggesting an interplay between chromatin remodeling-dependent cisplatin resistance and autophagy. On comparing the staining intensity between cisplatin-sensitive and -insensitive tissues from OSCC patients, protein expression pattern of the selected histone protein genes were matched with the in vitro data. By examining the relationship between autophagy and chromatin remodeling genes, we identified a set of candidate genes with potential use as markers predicting chemoresistance in OSCC biopsy samples. | Oh, Su Young; Kim, Jinkyung; Lee, Kah Young; Lee, Heon-Jin; Kwon, Tae-Geon; Kim, Jin-Wook; Lee, Sung-Tak; Kim, Dae-Geon; Choi, So-Young; Hong, Su-Hyung | Kyungpook Natl Univ, Sch Dent, Dept Microbiol & Immunol, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral & Maxillofacial Surg, Daegu, South Korea | 57204016703; 56107874300; 57226450171; 36462383000; 35205433300; 55862646000; 55931708300; 57226434973; 57202918688; 8691449100 | dentalchoi@knu.ac.kr;hongsu@knu.ac.kr; | CELL DEATH & DISEASE | CELL DEATH DIS | 2041-4889 | 15 | 8 | SCIE | CELL BIOLOGY | 2024 | 9.6 | 14.0 | 2.32 | 2025-05-07 | 6 | 7 | EPIGENETIC CONTROL; MECHANISMS; CANCER; HEAD | Animals; Antineoplastic Agents; Autophagy; Carcinoma, Squamous Cell; Cell Line, Tumor; Chromatin Assembly and Disassembly; Cisplatin; Drug Resistance, Neoplasm; Gene Expression Regulation, Neoplastic; Histones; Humans; Mice; Mice, Nude; Mouth Neoplasms; Xenograft Model Antitumor Assays; autophagy related protein; bafilomycin A1; chloroquine; cisplatin; hist1h3d protein; hist3h2a protein; hist3h2b protein; histone; histone H2A; histone H2B; histone H3; histone H4; messenger RNA; microphthalmia associated transcription factor; microtubule associated protein; nucleosome assembly protein 1; nucleosome assembly protein 1 like 2; small interfering RNA; unclassified drug; antineoplastic agent; cisplatin; histone; animal experiment; animal model; apoptosis; Article; autophagy (cellular); cancer resistance; cancer survival; cell viability; chemosensitivity; chromatin assembly and disassembly; chromatin structure; cisplatin-resistant cell line; controlled study; differential gene expression; disease free survival; DNA microarray; down regulation; drug efficacy; FaDu cell line; gain of function mutation; gene cluster; gene expression profiling; gene knockdown; gene ontology; gene overexpression; human; human tissue; in vitro study; loss of function mutation; male; monotherapy; mouse; mouth squamous cell carcinoma; mRNA expression level; nonhuman; nucleosome; organoid; post treatment survival; promoter region; protein expression level; three dimensional cell culture; transcription regulation; tumor spheroid; tumor volume; tumor xenograft; two dimensional cell culture; UM-SCC-1 cell line; upregulation; animal; drug effect; drug resistance; drug screening; drug therapy; gene expression regulation; genetics; metabolism; mouth tumor; nude mouse; pathology; squamous cell carcinoma; tumor cell line | English | 2024 | 2024-08-13 | 10.1038/s41419-024-06975-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Cobalt-based metal-organic framework/nickel-cobalt sulphide composite nanopetal arrays for high-performance hybrid coin cell supercapacitor | Affordable, environmentally friendly, and straightforward techniques, such as chemical bath deposition and electrodeposition, were employed to create a composite material consisting of cobalt metal-organic framework (Co-MOF) and nickel cobalt sulfide (NCS) on a nickel foam substrate. Comprehensive characterization was carried out to assess the resulting binder-free electrodes' structural, morphological, and electrochemical properties, including Co-MOF, NCS, and the Co-MOF/NCS composite. Morphological analysis revealed a highly ordered, porous, interconnected nanostructure resembling petal-like arrays in the Co-MOF/NCS composite. Notably, the electrochemical performance of the Co-MOF/NCS composite surpassed that of both pristine Co-MOF and NCS. It achieved the highest areal capacitance of 1.59 F/cm2 at 1 mA/cm2 current density. Furthermore, the Co-MOF/NCS composite demonstrated remarkable cyclic stability and capacity retention, preserving 83.80 % of its capacity after 15,000 cycles and 89.58 % after 10,000 cycles. The exceptional electrochemical behavior can be attributed to the unique nanopetal structure, which promotes the intercalation of electrolyte ions, provides numerous active sites, and ensures good electrical conductivity. A hybrid asymmetric coin cell supercapacitor was constructed to highlight its practical utility in energy storage. It uses Co-MOF/NCS nanopetal arrays as the positive electrode and an activated carbon film as the negative electrode. The fabricated asymmetric coin cell supercapacitor exhibited outstanding electrochemical performance, achieving a high energy density (ED) of 0.215 mW/cm2 (38.47 Wh/kg) at a power density (PD) of 1.778 mW/cm2 (3175.3 W/kg), with a retention capability of 88.07 % over 10,000 cycles. © 2024 Elsevier Ltd | Velhal, Ninad B.; Maile, Nagesh C.; Paeng, Changung; Lee, Huijin; Kim, Taewook; Kim, Jisoo; Yim, Changyong | Department of Energy Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea; School of Chemical Engineering, Institute for Environment and Energy, Pusan National University, Busan, 46241, South Korea; Department of Energy Materials & Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea; Department of Energy Materials & Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea; Department of Energy Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Department of Energy Materials & Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Department of Advanced Science and Technology Convergence, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Convergence Research Center of Mechanical and Chemical Engineering (CRCMCE), Kyungpook National University (KNU), 2559 Gyeongsang-daero, Sangju, 37224, Gyeongbuk, South Korea; Department of Advanced Science and Technology Convergence, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Department of Precision Mechanical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Convergence Research Center of Mechanical and Chemical Engineering (CRCMCE), Kyungpook National University (KNU), 2559 Gyeongsang-daero, Sangju, 37224, Gyeongbuk, South Korea; Department of Energy Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Department of Energy Materials & Chemical Engineering, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Department of Advanced Science and Technology Convergence, Kyungpook National University (KNU), 2559 Gyeongsang-Daero, Sangju, 37224, Gyeongbuk, South Korea, Convergence Research Center of Mechanical and Chemical Engineering (CRCMCE), Kyungpook National University (KNU), 2559 Gyeongsang-daero, Sangju, 37224, Gyeongbuk, South Korea | 56116686900; 57193804539; 58161154100; 58895644700; 57030752600; 57192647685; 36877182000 | taewook@knu.ac.kr;js.kim@knu.ac.kr; | Journal of Energy Storage | J ENERGY STORAGE | 2352-152X | 2352-1538 | 90 | SCIE | ENERGY & FUELS | 2024 | 9.8 | 14.0 | 4.51 | 2025-05-07 | 19 | Chemical bath deposition; Cobalt-MOF; Coin cell supercapacitor; Composite; Electrodeposition; Nanopetals arrays; Nickel cobalt sulfide | Activated carbon; Carbon films; Cobalt compounds; Crystalline materials; Electrochemical electrodes; Electrodeposition; Electrolytes; Foams; Nickel compounds; Organometallics; Sulfur compounds; Chemical-bath deposition; Cobalt sulphides; Cobalt-based; Cobalt-MOF; Coin cell supercapacitor; Coin cells; Electrochemical performance; Framework nickel; Metalorganic frameworks (MOFs); Nanopetal array; Supercapacitor | English | Final | 2024 | 10.1016/j.est.2024.111764 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Core-shell carbon@Ni2 (CO3 )(OH)2 particles as advanced cathode materials for hybrid supercapacitor: The key role of carbon for enhanced electrochemical properties | Three-dimensional porous Ni2(CO3)(OH)2 compounds were grown on carbon nanopowder using a facile hydrothermal method for the production of core-shell carbon@Ni2(CO3)(OH)2 compounds. This work successfully overcame the shortcomings related to the low electrical conductivity and poor electrical stability caused by the presence of hollows in the Ni2(CO3)(OH)2 structure. The hollow spaces were filled with carbon powder, which acted as a seed material, yielding an ideal electrode material with a large specific surface area, high electrical conductivity, and good stability. A Ni2(CO3)(OH)2 electrode containing 50 mg of carbon powder could store more energy than a Ni2(CO3)(OH)2 electrode without carbon seed materials. The Ni2(CO3)(OH)2 electrode comprising 50 mg of carbon powder has a considerably high specific capacity (181.7 mAh g-1 at 3 A g-1) and excellent cycling stability (77.9 % capacity retention after 5000 cycles), which is 1.5 times higher than that of the Ni2(CO3)(OH)2 electrode without carbon powder. Moreover, an asymmetric supercapacitor using Ni2(CO3)(OH)2 containing 50 mg of carbon powder as the positive electrode and graphene as the negative electrode exhibits a high energy density of 34.2 Wh kg- 1 and a power density of 176.1 W kg- 1 at a current density of 2 A g-1. Using a combination of carbon and a Ni2(CO3)(OH)2 nanowire compound to increase the electrochemical property and specific surface area, respectively, a suitable synergistic effect can be obtained, which may pave the way for efficient electrode design for high-performance supercapacitors. | Lee, Damin; Kim, Dong Hwan; Roh, Jong Wook; Keppetipola, Nilanka M.; Toupance, Thierry; Cojocaru, Ludmila; Kim, Jeongmin | DGIST, Div Nanotechnol, 333 Techno Jungang Daero, Daegu 42988, South Korea; Kyungpook Natl Univ, Reg Leading Res Ctr Smart Energy Syst, Daegu 41566, South Korea; Univ Bordeaux, CNRS, UMR 5255, ISM,Bordeaux INP,Grp Chim Mol & Materiaux C2M, 351 Cours Liberat, F-33405 Talence, France; Coll France, UMR 8260, Chim Solide & Energie CSE, F-75231 Paris, France; Komaba Inst Sci KIS, Grad Sch Arts & Sci, 4-6-1 Komaba, Meguro, Tokyo 1538904, Japan | TOUPANCE, Thierry/O-3368-2018; Cojocaru, Ludmila/HKV-3402-2023; Kim, Donghwan/KQT-9371-2024 | 57194601076; 57195540717; 25638796100; 57221673990; 6701783693; 36500685000; 57203325094 | damin91@knu.ac.kr;cojocaru@g.ecc.u-tokyo.ac.jp;jkim@dgist.ac.kr; | JOURNAL OF ENERGY STORAGE | J ENERGY STORAGE | 2352-152X | 2352-1538 | 97 | SCIE | ENERGY & FUELS | 2024 | 9.8 | 14.0 | 1.97 | 2025-05-07 | 6 | 7 | Core -shell structure; Nanowires; Hydrothermal method; Faradaic capacitors; Supercapacitors | ASYMMETRIC SUPERCAPACITORS; ACTIVATED CARBON; PERFORMANCE; NICKEL; ELECTRODE; STORAGE; COMPOSITES; NANOSHEET; MICROSPHERES; NANOFLAKES | Core-shell structure; Faradaic capacitors; Hydrothermal method; Nanowires; Supercapacitors | Carbon; Cathodes; Electric conductivity; Electrochemical electrodes; Electrochemical properties; Hybrid materials; Shells (structures); Specific surface area; Supercapacitor; Carbon nanopowders; Carbon powder; Cathodes material; Core shell; Core shell structure; Electrical conductivity; Electrical stability; Faradaic capacitor; Hybrid supercapacitors; Hydrothermal methods; Nanowires | English | 2024 | 2024-09-10 | 10.1016/j.est.2024.112944 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficient capture of particulate matter with composite air filters comprising bamboo-derived nanofiber and base paper | Particulate-matter (PM) air filters comprising chemically synthesized polymers and petroleum-based materials are not environmentally sustainable because they do not biodegrade, causing secondary environmental pollution. To overcome this problem, we synthesized and analyzed the PM-capturing performance of composite sandwichstructured air filters containing bamboo-derived lignocellulose nanofibers and lignocellulose base paper. Bamboo pulp was produced through an organosolv process, and lignocellulose nanofibers and lignocellulose base paper were manufactured via electrospinning and paper processes, respectively. The manufacturing process was not only optimized via a rheological analysis of the precursor solution with different mixed solvent composition (6:4, 5:5, and 4:6 of 1-ethyl-3-methylimidazolium acetate:dimethylformamide) and different lignocellulose weight percent (3.3, 4.0, and 4.6 wt%), but also via nanofiber characterization, including electrospinnability, diameter distribution, and basis weight. The base paper condition was optimized based on analyses of the air permeability, PM filtration efficiency, and strength according to the paper thickness of 0.38 +/- 0.05 and 0.10 +/- 0.05 mm. As the lignocellulose nanofibers and base paper effectively captured particles smaller and larger than 2.5 mu m, respectively, the structure of their composite sandwich-structured air filter was optimized to improve its PMcapturing performance. The study results provide new insights into the manufacturing of highly efficient PM air filters suitable for practical applications with diverse PM size distributions. | Kim, Min Ji; Kim, Kang-Jae; Kim, Seung Geun; Oh, Soong Ju; Yun, Ji Sun | Korea Inst Ceram Engn & Technol, New Growth Mat Div, 101,Soho ro, Jinju 52851, South Korea; Korea Univ, Dept Mat Sci & Engn, Seoul 02841, South Korea; Kyungpook Natl Univ, Sch Forestry Sci & Landscape Architecture, Major Wood & Paper Sci, 80 Daehakro, Daegu 41566, South Korea; Jirisan Hanji, R&D Ctr, 26,Gwangchisaneop 2-gil, Namwon Si 55727, Jeonrabug Do, South Korea | Kim, Kang-Jae/K-3915-2019; Oh, Soong/C-8842-2015 | 58366277500; 35733947500; 58038858900; 36673541700; 55920249300 | susubin@kicet.re.kr; | JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING | J ENVIRON CHEM ENG | 2213-2929 | 2213-3437 | 12 | 5 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 7.2 | 14.0 | 0.34 | 2025-05-07 | 1 | 1 | Bamboo; Lignocellulose; Nanofiber; Composite material; Air filter; Particulate matter | IONIC LIQUIDS; ELECTROSPUN NANOFIBERS; BINARY-MIXTURES; CELLULOSE; DISSOLUTION; PRESSURE | Air filter; Bamboo; Composite material; Lignocellulose; Nanofiber; Particulate matter | Air Filters; Bamboo; Basis Weight; Lignocellulose; Paper; Performance; Processes; Air filters; Bamboo; Biodegradable polymers; Dimethylformamide; Lignin; Nanofibers; Particle size analysis; Base paper; Composite sandwiches; Composites material; Environmental pollutions; Particulate Matter; Performance; Petroleum-based materials; Polymer-based materials; Synthesised; Synthesized polymers; Lignocellulose | English | 2024 | 2024-10 | 10.1016/j.jece.2024.113726 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Electrocatalytic carbon dioxide conversion to formate using gas-diffusion electrodes with group 12-15 metals | The group 12-15 metals of the periodic table are considered promising catalysts for the electrochemical conversion of CO2 to formate. The activities of these metals are estimated and compared using bulk metals (i.e., metal plates) in conventional aqueous CO2 electrolysis systems. Herein, five group 12-15 metals (Cd, In, Sn, Pb, and Bi) in the particulate form are hydrothermally synthesized, and their catalytic activities in formate production are examined in the gas-diffusion electrode device with continuous CO2 supply, with catalyst mass loading and applied current density as independent variables. The faradic efficiency values lower than 80% are obtained for Pb and Cd regardless of the experimental conditions. By contrast, In, Sn, and Bi show the relatively reliable faradaic efficiency values of >80% and cathodic energy efficiency values of >45% at cathodic J of 100-300 mA cm(-2) (hence partial current density for formate, J(FM) similar to 250 mA cm(-2)). Surface characterization reveals the crystalline structures of BiOCl, Cd(OH)(2), In(OH)(3), PbO, and SnO2. Among the metals, Sn is further modified under a reductive atmosphere to increase its energy efficiency. The figures of merit (faradaic efficiency, current, and cathodic energy efficiency) for the modified Sn are marginally higher than those for the other Sn types. | Piao, Guangxia; Yu, Gukgyeong; Kim, Seonghun; Cha, Jin Sun; Han, Dong Suk; Park, Hyunwoong | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Korea Testing Lab, Mat Technol Ctr, Seoul 08389, South Korea; Qatar Univ, Ctr Adv Mat, Doha 2713, Qatar | Han, Dong SuK/AAX-9333-2021 | 57193277010; 58784406000; 55854379300; 35309753600; 36139213900; 7601565583 | hwp@knu.ac.kr; | JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING | J ENVIRON CHEM ENG | 2213-2929 | 2213-3437 | 12 | 3 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 7.2 | 14.0 | 0.34 | 2025-05-07 | 1 | 1 | CO2 reduction; Formate; Electrocatalyst; Hydrogen treatment; Defect | ELECTROCHEMICAL REDUCTION; CO2; WATER; COPPER; ELECTROREDUCTION; PHOTOSYNTHESIS; EFFICIENT; ACID | CO<sub>2</sub> reduction; Defect; Electrocatalyst; Formate; Hydrogen treatment | Bismuth compounds; Cadmium compounds; Carbon dioxide; Catalyst activity; Diffusion in gases; Electrodes; Energy efficiency; Indium compounds; Lead oxide; Tin oxides; Carbon dioxide conversions; CO 2 reduction; Electrocatalytic; Electrochemical conversion; Faradaic efficiencies; Formate; Gas diffusion electrodes; Hydrogen treatments; Periodic table; ]+ catalyst; Electrocatalysts | English | 2024 | 2024-06 | 10.1016/j.jece.2024.112623 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Geometric optimization of fin structures for accelerated melting of phase change material in a triplex tube heat exchanger | This study aims to optimize the thermal energy storage performance of a novel Triplex Tube Heat Exchanger (TTHX) embedded with Phase Change Material (PCM). The PCM is placed in the inner tube and the outer annulus, while the heat transfer fluid (HTF) flows through the middle annulus section. This TTHX configuration outperforms conventional designs by effectively dividing the PCM volume into two distinct sections, consequently enhancing the interaction between HTF and PCM. The experimental results show that the PCM placed in the inner tube melts faster than the PCM in the outer annulus, indicating a need for fins to enhance heat transfer in the outer annulus. In this regard, several designs of the branched fin structures are proposed for the outer annulus region. Taguchi optimization method is used to identify the optimum fin design configuration by considering branched fin designs (F), their angular placement around the periphery of the middle tube (alpha), and the branch angle (beta) as the independent design factors. The objective is to optimize the fin configuration so as to decrease the melt time of the PCM. All the cases of the L16 Taguchi design array are simulated numerically using the enthalpy-porosity model in ANSYS Fluent 2021 R2. The target parameters are the melt time, average temperature, and the energy storage features which are continuously recorded. The main effects plots of the Taguchi analysis suggest an optimum geometry as the one having fin design of F4 (containing angled and straight branches), alpha as 60 degrees and beta equal to 50 degrees. The optimum fin configuration reduces the melt time by 35 % in comparison to the reference base case design. The energy storage characteristics are also improved with the optimum design storing 267 kJ/kg energy at 71.92 min, while the base case stores 208 kJ/kg at the same time. This gain has been achieved due to faster energy transfer rate which is increased to a value of 0.062 kW/kg for the optimum design as compared to 0.042 kW/kg for the base case, reporting an increase of 47.6 % in the energy transfer rate. | Hussain, Bilal; Irfan, Muhammad; Khan, Muhammad Mahabat; Ullah, Saif; ul Hasnain, Fakhar | Capital Univ Sci & Technol, Dept Mech Engn, Islamabad 45750, Pakistan; Kyungpook Natl Univ, Dept Mech Engn, Taegu, South Korea | Irfan, Muhammad/ITT-2985-2023; Khan, Muhammad/J-9077-2019; hussain, bilal/X-8876-2019 | 59872376200; 57191273029; 57190667751; 58588826400; 57856336600 | m.irfan@cust.edu.pk; | JOURNAL OF ENERGY STORAGE | J ENERGY STORAGE | 2352-152X | 2352-1538 | 79 | SCIE | ENERGY & FUELS | 2024 | 9.8 | 14.0 | 2.82 | 2025-05-07 | 10 | 12 | Phase change material; Triplex tube heat exchanger; Thermal energy storage; Thermal performance enhancement; Branched fins; Heat transfer rate | CONVECTION; STORAGE | Branched fins; Heat transfer rate; Phase change material; Thermal energy storage; Thermal performance enhancement; Triplex tube heat exchanger | Energy transfer; Fins (heat exchange); Heat storage; Heat transfer; Phase change materials; Storage (materials); Structural design; Structural optimization; Taguchi methods; Tubes (components); Branched fin; Fin configuration; Fins structures; Heat transfer fluids; Heat transfer rate; Inner tubes; Thermal energy storage; Thermal performance enhancements; Triplex tube heat exchanger; Tube heat exchangers; Thermal energy | English | 2024 | 2024-02-15 | 10.1016/j.est.2023.110162 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Mitigating PTFE decomposition in ultra thick dry-processed anodes for high energy density lithium-ion batteries | Dry electrode technology is a next-generation method for manufacturing lithium-ion batteries because it is useful for fabricating thick electrodes without solvents, facilitating high energy densities and cutting down on the battery manufacturing costs. However, the commonly used polytetrafluoroethylene (PTFE) binder in dry electrode technology undergoes severe decomposition in dry-processed anodes during the first lithiation process due to its low lowest unoccupied molecular orbital level. This phenomenon seriously aggravates battery performance, such as in terms of the initial coulombic efficiency and cycle life. Thus, a strategy to suppress this irreversible reaction of PTFE should be established for dry-processed anodes to increase the energy density of LIBs without adverse effects on battery performance. To address this challenge, in this work, fluoroethylene carbonate (FEC) as an electrolyte additive has been introduced to form a preemptive and stable FEC-derived solid electrolyte interface (SEI) to protect a graphite and the PTFE binder. This SEI considerably alleviates the irreversible reaction of PTFE, thereby securing the reversible capacity and maintaining the structure of the electrode through the great binding properties. These results provide guidance for increasing the electrochemical stability in dryprocessed anode systems, which gets closer the innovative dry anode technology for cost-effectiveness and high energy density. | Han, Seungmin; Noh, Eui-Hyurk; Chae, Sujong; Kwon, Kihwan; Lee, Juhyun; Woo, Ji-Su; Park, Seongsu; Lee, Jung Woo; Kim, Patrick Joohyun; Song, Taeseup; Kwak, Won-Jin; Choi, Junghyun | Korea Inst Ceram Engn & Technol, Energy Storage Mat Ctr, Jinju 52851, South Korea; Hanyang Univ, Dept Energy Engn, 222 Wangsimni Ro, Seoul 04763, South Korea; UNIST, Sch Energy & Chem Engn, Ulsan 44919, South Korea; Ajou Univ, Dept Energy Syst Res, Suwon 16499, South Korea; Pukyong Natl Univ, Dept Ind Chem, 45 Yongso Ro, Pusan 48513, South Korea; Pusan Natl Univ, Dept Mat Sci & Engn, Busan 46241, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Gachon Univ, Sch Chem Biol & Battery Engn, Seongnam Si 13120, Gyeonggi Do, South Korea | ; Chae, Sujong/MHP-9006-2025; Kwak, Won-Jin/GPX-5328-2022 | 58619237900; 59004380500; 56258842100; 58045803700; 59832117900; 57949453700; 57191228569; 57208309536; 57195611779; 25825726200; 56275955200; 59883103900 | tssong@hanyang.ac.kr;wjkwak@unist.ac.kr;junghchoi@gachon.ac.kr; | JOURNAL OF ENERGY STORAGE | J ENERGY STORAGE | 2352-152X | 2352-1538 | 96 | SCIE | ENERGY & FUELS | 2024 | 9.8 | 14.0 | 2.25 | 2025-05-07 | 14 | 14 | Lithium -ion batteries; Dry -processed anode; Thick film electrode; Fluoroethylene carbonate; Electrolyte additive | REDUCTION; VEHICLES | Dry-processed anode; Electrolyte additive; Fluoroethylene carbonate; Lithium-ion batteries; Thick film electrode | Additives; Binding energy; Cost effectiveness; Ions; Lithium-ion batteries; Molecular orbitals; Solid electrolytes; Solid-State Batteries; Thick films; 'Dry' [; Battery performance; Dry electrode; Dry-processed anode; Electrode technology; Electrolyte additives; Fluoroethylene carbonates; Higher energy density; Irreversible reactions; Thick-film electrodes; Anodes | English | 2024 | 2024-08-15 | 10.1016/j.est.2024.112693 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | PDK4-mediated metabolic reprogramming is a potential therapeutic target for neovascular age-related macular degeneration | Age-related macular degeneration (AMD) causes severe blindness in the elderly due to choroidal neovascularization (CNV), which results from the dysfunction of the retinal pigment epithelium (RPE). While normal RPE depends exclusively on mitochondrial oxidative phosphorylation for energy production, the inflammatory conditions associated with metabolic reprogramming of the RPE play a pivotal role in CNV. Although mitochondrial pyruvate dehydrogenase kinase (PDK) is a central node of energy metabolism, its role in the development of CNV in neovascular AMD has not been investigated. In the present study, we used a laser-induced CNV mouse model to evaluate the effects of Pdk4 gene ablation and treatment with pan-PDK or specific PDK4 inhibitors on fluorescein angiography and CNV lesion area. Among PDK isoforms, only PDK4 was upregulated in the RPE of laser-induced CNV mice, and Pdk4 gene ablation attenuated CNV. Next, we evaluated mitochondrial changes mediated by PDK1-4 inhibition using siRNA or PDK inhibitors in inflammatory cytokine mixture (ICM)-treated primary human RPE (hRPE) cells. PDK4 silencing only in ICM-treated hRPE cells restored mitochondrial respiration and reduced inflammatory cytokine secretion. Likewise, GM10395, a specific PDK4 inhibitor, restored oxidative phosphorylation and decreased ICM-induced upregulation of inflammatory cytokine secretion. In a laser-induced CNV mouse model, GM10395 significantly alleviated CNV. Taken together, we demonstrate that specific PDK4 inhibition could be a therapeutic strategy for neovascular AMD by preventing mitochondrial metabolic reprogramming in the RPE under inflammatory conditions. | Kim, Juhee; Jeon, Yujin; Son, Jinyoung; Pagire, Haushabhau S.; Pagire, Suvarna H.; Ahn, Jin Hee; Uemura, Akiyoshi; Lee, In-Kyu; Park, Sungmi; Park, Dong Ho | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Biomed Sci, Daegu, South Korea; BK21 FOUR KNU Convergence Educ Program Biomed Sci, Daegu, South Korea; Gwangju Inst Sci & Technol, Dept Chem, Gwangju, South Korea; JD Biosci Inc, R&D Ctr, Gwangju, South Korea; Nagoya City Univ, Grad Sch Med Sci, Dept Ophthalmol & Visual Sci, Nagoya, Japan; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med, Daegu, South Korea | ; Uemura, Akiyoshi/I-7510-2017; Ahn, Jin/C-6122-2019 | 57219717701; 58699202700; 59253927400; 55599893000; 56716279400; 56714432600; 7102872436; 36071537600; 56252420000; 36676632900 | smpark93@gmail.com;DongHo_Park@knu.ac.kr; | CELL DEATH & DISEASE | CELL DEATH DIS | 2041-4889 | 15 | 8 | SCIE | CELL BIOLOGY | 2024 | 9.6 | 14.0 | 0 | 2025-05-07 | 1 | 1 | RETINAL-PIGMENT EPITHELIUM; EXPRESSION; CYTOKINES | Animals; Choroidal Neovascularization; Disease Models, Animal; Humans; Macular Degeneration; Metabolic Reprogramming; Mice; Mice, Inbred C57BL; Mitochondria; Oxidative Phosphorylation; Pyruvate Dehydrogenase Acetyl-Transferring Kinase; Retinal Pigment Epithelium; cytokine; gm 10395; heat shock protein 90; interleukin 1beta; interleukin 6; interleukin 8; messenger RNA; monocyte chemotactic protein 1; protein serine threonine kinase inhibitor; pyruvate dehydrogenase kinase 4; small interfering RNA; unclassified drug; PDK4 protein, human; Pdk4 protein, mouse; pyruvate dehydrogenase kinase; aerobic metabolism; aged; animal experiment; animal model; animal tissue; Article; controlled study; cytokine release; enzyme linked immunosorbent assay; female; fluorescence angiography; gene silencing; human; immunohistochemistry; knockout mouse; laser-induced choroidal neovascularization; male; metabolic reprogramming; mitochondrial respiration; mouse; nonhuman; oxidative phosphorylation; oxygen consumption rate; practice guideline; real time polymerase chain reaction; upregulation; Western blotting; animal; C57BL mouse; disease model; drug effect; drug therapy; macular degeneration; metabolic reprogramming; metabolism; mitochondrion; pathology; retinal pigment epithelium; subretinal neovascularization | English | 2024 | 2024-08-09 | 10.1038/s41419-024-06968-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Redefining progress, challenges, and future opportunities of mixed-matrix membranes from an engineering perspective for commercial gas separation applications: A review | Mixed-matrix membranes (MMMs) for gas separations integrate inorganic fillers into a polymer matrix, combining the cost-effective scalability of polymer membranes with the superior performance of expensive inorganic ones. Over the past three decades, the development of MMMs has focused on addressing scientific challenges such as filler agglomeration and poor interfacial interaction, which significantly impact the performance and scalability. Despite breakthroughs in mitigating these issues, translating these achievements into commercially viable solutions has been limited. This review reevaluates the developments, challenges, and prospects of MMMs, emphasizing the engineering perspective in addressing the practical aspects of scale-up and commercialization. It highlights, in particular, fabrication strategies and the importance of engineering approaches in realizing their commercial potential. Furthermore, it discusses the advantages, disadvantages, scalability, and cost implications of both traditional and recent MMM processing methods, outlining the benchmarks required for MMMs to be commercially viable on a large scale. This perspective encourages a shift towards application-driven research to advance the development of MMMs that meet both performance and commercialization criteria. | Hua, Yinying; Park, Sunghwan; Jeong, Hae-Kwon | Texas A&M Univ, Artie McFerrin Dept Chem Engn, 3122 TAMU, College Stn, TX 77843 USA; Kyungpook Natl Univ, Dept Energy Chem Engn, 2559 Gyeongsang Daero, Sangju 37224, Gyeongsangbuk, South Korea; Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, 2559 Gyeongsang Daero, Sangju 37224, Gyeongsangbuk, South Korea; Texas A&M Univ, Dept Mat Sci & Engn, 3122 TAMU, College Stn, TX 77843 USA | Hua, Yinying/GRF-1267-2022 | 57190427313; 56402062100; 7401619878 | sunghwan@knu.ac.kr;hjeong7@tamu.edu; | JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING | J ENVIRON CHEM ENG | 2213-2929 | 2213-3437 | 12 | 5 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 7.2 | 14.0 | 1.06 | 2025-05-07 | 11 | 13 | Mixed-matrix membranes; Gas separations; Membrane fabrications; Engineering perspective; Scale-up; Commercialization | METAL-ORGANIC FRAMEWORK; HOLLOW-FIBER MEMBRANES; THIN-FILM NANOCOMPOSITE; POLYLACTIDE/LAYERED SILICATE NANOCOMPOSITES; WALLED CARBON NANOTUBES; CO2 SEPARATION; HIGH-PERFORMANCE; DUAL-LAYER; ZEOLITE; POLYMER | Commercialization; Engineering perspective; Gas separations; Membrane fabrications; Mixed-matrix membranes; Scale-up | Cost effectiveness; Fabrication; Fillers; Gas permeable membranes; Commercialisation; Cost effective; Engineering perspective; Gas separations; Inorganic-fillers; Membrane fabrication; Mixed-matrix membranes; Performance; Polymer matrices; Scale-up; Scalability | English | 2024 | 2024-10 | 10.1016/j.jece.2024.113753 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Selective chlorine evolution reaction using Pt-RuO2 electrocatalysts in brackish water and seawater at circum-neutral pH and its application to seawater desalination | Precious metal-based mixed metal oxides have been widely used as catalysts for the chlorine evolution reaction (CER). However, a concurrent oxygen evolution reaction (OER) leads to insufficient selectivity for CER at circum-neutral pH. Herein, nanoparticulate Pt-RuO2 (PRO) is synthesized with various Pt/Ru ratios at sub-boiling temperatures, followed by post-annealing. The synthetic conditions significantly influence the physicochemical properties (crystalline structures, morphologies, surface areas, double-layer capacitance, and charge transfer resistance) and the electrocatalytic activities of CER in NaCl solutions (0.137 and 0.5 M) and seawater (with a salinity of 3.6 g L-1). Among PRO-x@y samples (where x is the mole fraction of Pt in the mixed Pt and Ru precursor solutions, and y is the annealing temperature [degrees C]), PRO-0.2@800 and PRO-0.8@500 show remarkable faradaic efficiencies (FEs) for CER (CER-FE). Despite their similar FEs (CER-FEs of approximately 95 % and 99 %, and OER-FEs of 4-6 % and <1 %, for PRO-0.2 and PRO-0.8, respectively), the Pt-rich PRO requires less potential for the same current density (J) and exhibits excellent stability at J = 800 mA cm(-2) over 250 h in seawater at circum-neutral pH. The optimized PRO electrode is further used for seawater desalination and simultaneous production of HClO, achieving FEs of similar to 100 %. Finally, various electrochemical analyses are conducted to elucidate the CER mechanism. | Liang, Nan-Nan; Han, Dong Suk; Kim, Seonghun; Park, Hyunwoong | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Qatar Univ, Ctr Adv Mat, POB 2713, Doha, Qatar | ; Han, Dong SuK/AAX-9333-2021 | 57800564000; 36139213900; 55854379300; 7601565583 | ksh86@knu.ac.kr;hwp@knu.ac.kr; | JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING | J ENVIRON CHEM ENG | 2213-2929 | 2213-3437 | 12 | 5 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 7.2 | 14.0 | 0.34 | 2025-05-07 | 2 | 3 | Mixed metal oxides; Oxygen evolution reaction; Chlorine evolution reaction; Seawater electrolysis; Selectivity | ELECTROCHEMICAL OXIDATION; MOLECULAR-HYDROGEN; NANOPARTICLES; CHLORALKALI; ELECTRODE; OXYGEN | Chlorine evolution reaction; Mixed metal oxides; Oxygen evolution reaction; Seawater electrolysis; Selectivity | Annealing; Charge transfer; Desalination; Electrocatalysts; Oxygen; Physicochemical properties; Platinum compounds; Sodium chloride; Chlorine evolution; Chlorine evolution reaction; Evolution reactions; Faradaic efficiencies; Mixed metal oxide; Neutral pH; RuO 2; Seawater desalination; Seawater electrolysis; Selectivity; Ruthenium compounds | English | 2024 | 2024-10 | 10.1016/j.jece.2024.113622 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Synergistic control of cohesive and adhesive forces in anchored porous CoMn 2 O 4 for superior reversible lithium-ion storage and high energy-power density | Today, the growing demand for environmentally friendly energy storage systems has prompted extensive research on improving electrode performance due to the rapid advancement of portable electronic devices. In this investigation, we successfully synthesized CoMn 2 O 4 (CMO) microspheres featuring uniformity, as well as hollow and porous structures. Through the controlled cohesive and adhesive forces during the calcination process, we achieved the synthesis of CoMn 2 O 4 microspheres with porous and hollow characteristics, utilizing CoMn-glycolate solid microspheres as the precursor. By integrating a three-dimensional network of reduced graphene oxide (rGO) anchored CoMn 2 O 4 (P-CMO) microspheres, we enhanced the surface area and accelerated ion diffusion in Li -ion storage devices. The rGO-P-CMO composite achieved a discharge capacity of 1457 mAh g -1 at 100 mA g -1 , surpassing the theoretical limit, and retained 80 % capacitance at 1000 mA g -1 . Besides, we constructed a novel rechargeable lithium -ion battery (LIB) full cell utilizing the rGO-P-CMO microspheres as the anode and the Li 1.2 Mn 0.54 Ni 0.13 Co 0.13 O 2 (LMNCO) as the cathode. The LIB full cell (rGO-P-CMO||LMNCO) exhibited a discharge capacity of 147 mA g -1 and achieved a practical energy density of 220.5 Wh kg - 1 , considering the combined weight of the active electrode materials. Therefore, the exceptional electrochemical performance displayed by the proposed LIB full cell configuration holds significant potential in advancing the development of next -generation, high-performance batteries tailored for electric vehicle implementations. | Alagar, Srinivasan; Karuppiah, Chelladurai; Jeong, Sang Mun; Mariappan, Ramalakshmi; Piraman, Shakkthivel; Yang, Chun-Chen | Alagappa Univ, Dept Nanosci & Technol, Sustainable Energy & Smart Mat Res Lab, Sci Campus, Karaikkudi 630002, Tamil Nadu, India; Ming Chi Univ Technol, Battery Res Ctr Green Energy, New Taipei City 24301, Taiwan; Chungbuk Natl Univ, Dept Chem Engn, Cheongju 28644, Chungbuk, South Korea; Univ Technol & Appl Sci, Dept Appl Sci, Muscat 133, Oman; Kyungpook Natl Univ, Dept Chem, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, 80 Daehakro, Daegu 41566, South Korea | A, SRINIVASAN/L-8204-2017; Karuppiah, Chelladurai/H-7068-2019 | 56610159700; 55910716400; 58834913100; 57725526700; 55641100500; 35241314100 | apsakthivel@yahoo.com;ccyang@mail.mcut.edu.tw; | JOURNAL OF ENERGY STORAGE | J ENERGY STORAGE | 2352-152X | 2352-1538 | 88 | SCIE | ENERGY & FUELS | 2024 | 9.8 | 14.0 | 0.28 | 2025-05-07 | 2 | 2 | Anode; High discharge capacity; Li 1.2 Mn 0.54 Ni 0.13 Co 0.13 O 2; LIB full-cell; Energy-power density | HOLLOW SPHERES; PERFORMANCE; ANODES; NANOPARTICLES; MICROSPHERES; FABRICATION; CAPACITY; MNCO2O4; NANOSHEETS; BATTERY | Anode; Energy-power density; High discharge capacity; Li<sub>1.2</sub>Mn<sub>0.54</sub>Ni<sub>0.13</sub>Co<sub>0.13</sub>O<sub>2</sub> ; LIB full-cell; rGO-porous CoMn<sub>2</sub>O<sub>4</sub> microspheres | Adhesives; Cathodes; Electric discharges; Graphene; Ions; Lithium compounds; Lithium-ion batteries; Manganese compounds; Microspheres; Nickel compounds; Storage (materials); Virtual storage; Cohesive force; Discharge capacities; Energies (power); Energy-power density; High discharge capacity; Li1.2mn0.54ni0.13co0.13O2; Lithium-ion battery full-cell; Power densities; Reduced graphene oxide-porous comn2O4 microsphere; Reduced graphene oxides; Anodes | English | 2024 | 2024-05-30 | 10.1016/j.est.2024.111378 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Synthesis and properties of a ternary transition metal compound as positive electrode for high-performance supercapacitors | A nanostructured NixFeyCuz(CO3)(OH)2 electrode with a large surface area was deposited on a Ni-foam substrate using a facile hydrothermal method. The well-organized microscopic and free-standing nano-sized ternary metal compounds exhibited high electrical conductivity and competent ion transport ability. This composite is particularly attractive for high-performance power-storage systems owing to its binder-free nature and exceptional value as a current-carrying electrode. Ternary electrodes containing three transition metals have a higher entropy than binary electrodes, which reduces the movement distance of ions on the electrode surface and enhances key electrochemical advantages, thereby providing a high specific capacitance with durability and cycling stability when coated with a highly conductive electrochemical pattern. The NixFeyCuz(CO3)(OH)2 compound demonstrated remarkable specific surface area of 106 m2 g-1 and high specific capacities of 271.8 and 75.2 mAh g-1 at current densities of 3 and 15 A g-1. In addition, an asymmetric supercapacitor fabricated with the NixFeyCuz(CO3)(OH)2 compound as the positive electrode and graphene as the negative electrode exhibited a high energy density of 55.1 W h kg-1 at power and current densities of 398.5 W kg-1 and 2 A g-1, respectively, as well as a remarkable cycling stability of 84.3 %, which was maintained following 10,000 long cycles. | Km, Dasha Kumar; Kim, Kwang Ho; Saeed, Ghuzanfar; Toupance, Thierry; Jeong, Young-Keun; Lee, Damin | Pusan Natl Univ, Sch Convergence Sci, San 30 Jangjeon Dong, Busan 609735, South Korea; Pusan Natl Univ, Global Frontier R&D Ctr Hybrid Interface Mat, San 30 Jangjeon Dong, Busan 609735, South Korea; Kyungpook Natl Univ, Reg Leading Res Ctr Smart Energy Syst, Daegu 41566, South Korea; DGIST, Div Nanotechnol, 333 Techno Jungang Daero, Daegu 42988, South Korea; Univ Bordeaux, Bordeaux INP, ISM, CNRS,UMR 5255,Grp Chim Mol & Mat C2M, 351 Cours Liberat, F-33405 Talence, France | Kim, Hee-Je/O-3501-2019; TOUPANCE, Thierry/O-3368-2018 | 57868605600; 57199439961; 55918453900; 6701783693; 16316094700; 57194601076 | nano@pusan.ac.kr;damin91@knu.ac.kr; | JOURNAL OF ENERGY STORAGE | J ENERGY STORAGE | 2352-152X | 2352-1538 | 78 | SCIE | ENERGY & FUELS | 2024 | 9.8 | 14.0 | 4.51 | 2025-05-07 | 17 | 19 | Ternary-carbonate hydroxide; Faradaic capacitors; Hydrothermal method; Supercapacitors; Energy storage device | CUCO2O4 NANOSHEETS; NICKEL; COMPOSITES; HYDROXIDE; CAPACITY; GROWTH; XPS | Energy storage device; Faradaic capacitors; Hydrothermal method; Supercapacitors; Ternary-carbonate hydroxide | Electrochemical electrodes; Hydrothermal synthesis; Refractory metal compounds; Transition metal oxides; Transition metals; Cycling stability; Electrochemicals; Energy storage device; Faradaic capacitor; Hydrothermal methods; Performance; Positive electrodes; Property; Ternary-carbonate hydroxide; Transition-metal compounds; Supercapacitor | English | 2024 | 2024-02-01 | 10.1016/j.est.2023.110032 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Synthesis of novel 2D g-C3N4/3D CoSe2 hierarchical microflower-like hybrids for high-performance energy-storage applications | The rapid development of new vehicles and portable electronics has continuously pressured advanced renewable energy-storage technologies to deliver exceptional energy-power outputs and long lifetimes. Hybrid supercapacitors attract attention owing to their outstanding power density, high specific capacitance, and excellent cycling stability. In this study, two-dimensional (2D) g-C3N4 nanosheets and 3D CoSe2 hierarchical microflower heterojunction electrodes were synthesized using a facile hydrothermal preparation method, and their electrochemical performances were evaluated. Surface morphology analysis demonstrated that the g-C3N4 nanosheets were well-dispersed on the CoSe2 hierarchical microflower surface. The interstitial contact between CoSe2 and gC3N4 effectively narrowed the bandgap energy, enhanced the electrical conductivity, and improved the electrochemical properties. Electrochemical analysis indicated rapid reaction kinetics and significant energy-storage capacity for the CoSe2/g-C3N4 heterojunction electrode. Notably, the CoSe2/g-C3N4 heterojunction electrode achieved a specific capacitance of 1024.4 F/g at 1 A/g. The assembled CoSe2/g-C3N4 heterojunction hybrid supercapacitor device exhibited a high energy (62 Wh/kg), high power density (775 W/kg), and remarkable lifespan after 10,000 cycles. The developed electrode is promising for energy-related device applications. | Wang, Rui; Dai, Aijia; Vijayalakshmi, Mule; Jang, Won Young; Kakarla, Raghava Reddy; Shim, Jaesool; Aminabhavi, Tejraj M.; Reddy, Ch.

| ○ | ○ | Article | Systematic analysis of dual-functional catalysts for simultaneous CO-NOx reduction: Toward an effective catalyst design strategy | The development of a multifunctional catalyst suitable for application in existing facilities with limited space, with specific emphasis on its capability to concurrently remove CO and NOx is vital for meeting stringent environmental regulations. This is particularly pertinent to industries such as liquefied natural gas-based power plants and multipollutant-emitting industrial facilities. Another important consideration is that the catalyst should operate over a wide temperature range to facilitate its application across various industrial sites. In this study, we synthesized vanadium-based catalysts with a series of noble metals (Pt, Pd, and Au). The V-W-Pd/TiO2 catalyst achieved a simultaneous CO-NOx reduction efficiency greater than 90% in the widest temperature range, 228-321 degrees C. The excellent catalytic activities resulted from the Pd active sites, which oxidated CO and adsorbed NOx. This enables the catalyst to easily participate in the NH3-SCR reaction and facilitates NOx reduction. Moreover, we systematically analyzed the reaction properties of each catalyst using diffuse reflectance infrared Fourier transform and temperature programmed desorption methods. This enabled the elucidation of the reaction characteristics and competitive adsorption properties of the catalysts. | Kim, Jeongtak; Jeong, Soon Kwan; Jeong, Min Hye; Choi, Sun A.; Shin, Kyuchul; Hwang, Sun-Mi | Korea Inst Energy Res KIER, Climate Change Res Div, Clean Air Res Lab, 152 Gajeongro, Daejeon 34129, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea | Hwang, Sun-Mi/LBH-0692-2024 | 57204511907; 23970861300; 56486866900; 55844617600; 14030501800; 25928373000 | kyuchul.shin@knu.ac.kr;smhwang@kier.re.kr; | JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING | J ENVIRON CHEM ENG | 2213-2929 | 2213-3437 | 12 | 3 | SCIE | ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL | 2024 | 7.2 | 14.0 | 0 | 2025-05-07 | 0 | 0 | Dual function catalyst; CO oxidation; Simultaneous emission reduction; Multiple air pollutants removal | NH3-SCR REACTION; PERFORMANCE; OXIDATION; NH3; DRIFT; FE; CU | CO oxidation; Dual function catalyst; Multiple air pollutants removal; NH<sub>3</sub>-SCR; Simultaneous emission reduction | Catalyst activity; Emission control; Environmental regulations; Gas plants; Nitrogen oxides; Temperature programmed desorption; Air pollutants; CO oxidation; Dual function; Dual function catalyst; Emission reduction; Multiple air pollutant removal; NH3-SCR; Pollutants removal; Simultaneous emission reduction; ]+ catalyst; Ammonia | English | 2024 | 2024-06 | 10.1016/j.jece.2024.113028 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
