| ○ | ○ | Article | Highly specific chimeric DNA-RNA-guided genome editing with enhanced CRISPR-Cas12a system | The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas12a system is composed of a Cas12a effector that acts as a DNA-cleaving endonuclease and a crispr RNA (crRNA) that guides the effector to the target DNA. It is considered a key molecule for inducing target-specific gene editing in various living systems. Here, we improved the efficiency and specificity of the CRISPR-Cas12a system through protein and crRNA engineering. In particular, to optimize the CRISPR-Cas12a system at the molecular level, we used a chimeric DNA-RNA guide chemically similar to crRNA to maximize target sequence specificity. Compared with the wild-type (wt)-Cas12a system, when using enhanced Cas12a system (en-Cas12a), the efficiency and target specificity improved on average by 2.58 and 2.77 times, respectively. In effector was used, the gene-editing efficiency and accuracy were simultaneously increased. These findings could contribute to highly accurate genome editing, such as human gene therapy, in the near future. | Kim, Hanseop; Lee, Wi-Jae; Kim, Chan Hyoung; Oh, Yeounsun; Gwon, Lee Wha; Lee, Hyomin; Song, Woojeung; Hur, Junho K.; Lim, Kyung-Seob; Jeong, Kang Jin; Nam, Ki-Hoan; Won, Young-Suk; Lee, Kyeong-Ryoon; Lee, Youngjeon; Kim, Young-Hyun; Huh, Jae-Won; Jun, Bong-Hyun; Lee, Dong-Seok; Lee, Seung Hwan | Korea Res Inst Biosci & Biotechnol KRIBB, Futurist Anim Resource & Res Ctr FARRC, Cheongju 28116, South Korea; Korea Res Inst Biosci & Biotechnol KRIBB, Natl Primate Res Ctr NPRC, Cheongju 28116, South Korea; Kyungpook Natl Univ, Sch Life Sci & Biotechnol, BK21 FOUR KNU Creat BioRes Grp, Daegu, South Korea; Konkuk Univ, Dept Biosci & Biotechnol, Seoul 143701, South Korea; Korea Univ Sci & Technol, KRIBB Sch Biosci, Dept Biomol Sci, Daejeon, South Korea; Korea Univ, Coll Life Sci & Biotechnol, Dept Biotechnol, Seoul 02841, South Korea; Korea Res Inst Biosci & Biotechnol KRIBB, Lab Anim Resource Ctr, Cheongju 28116, South Korea; Hanyang Univ, Grad Sch, Dept Med, Major Med Genet, Seoul 04763, South Korea; Hanyang Univ, Coll Med, Dept Genet, Seoul 04763, South Korea; Hanyang Univ, Grad Sch Biomed Sci & Engn, Seoul 04763, South Korea; Chungnam Natl Univ, Dept Biol Sci, Daejeon, South Korea; Univ Sci & Technol, Dept Biosci, Daejeon 34113, South Korea; Korea Univ Sci & Technol UST, KRIBB Sch Biosci, Dept Funct Genom, Daejeon, South Korea; Chung Ang Univ, Dept Life Sci, Seoul 06974, South Korea | ; Kim, Jonghwan/AAR-2815-2021; Kim, Junghwan/AAV-1973-2020; Hur, Junho/ADK-0757-2022; Lee, Youngjeon/LZH-8969-2025 | 57203630238; 57218165418; 57224822365; 57218169850; 56986646700; 59283800900; 57218860580; 35740323500; 36470521900; 56181213100; 55750745700; 15618909700; 35409534300; 57199022088; 54393408600; 16645802900; 35229652600; 57210068061; 57202327400 | bjun@konkuk.ac.kr;lee1@knu.ac.kr;lsh080390@cau.ac.kr; | MOLECULAR THERAPY NUCLEIC ACIDS | MOL THER-NUCL ACIDS | 2162-2531 | 28 | SCIE | MEDICINE, RESEARCH & EXPERIMENTAL | 2022 | 8.8 | 12.9 | 1.08 | 2025-06-25 | 12 | 11 | R-LOOP COMPLEX; WIDE SPECIFICITIES; CRISPR; CPF1; CAS9; ENDONUCLEASE; NUCLEASES; CLEAVAGE | chimeric DNA-RNA; efficient; en-Cas12a; gene therapy; genome editing; highly specific; RNA/DNA editing | article; clustered regularly interspaced short palindromic repeat; CRISPR Cas system; DNA RNA hybridization; DNA sequence; gene editing; gene therapy; human; wild type | English | 2022 | 2022-06-14 | 10.1016/j.omtn.2022.03.021 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Stabilization and Self-Passivation of Grain Boundaries in Halide Perovskite by Rigid Body Translation | The physical properties of grain boundaries in halide perovskites, especially their atomic structure, have not been fully understood yet. We report that Sigma 5 [130] symmetrical tilt grain boundaries can be stabilized by rigid body translation which is moving one side of the grain parallel with respect to the adjacent grain. Such reconstruction passivates grain boundaries by removing Pb-Pb and I-I interactions that introduce shallow defect states in the band gap. Rigid body translation also stabilizes the [110] antiphase boundary as well in both CsPbI3 and CsPbBr3. | Park, Ji-Sang | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea | 36671796300 | jsparkphys@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY LETTERS | J PHYS CHEM LETT | 1948-7185 | 13 | 20 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2022 | 5.7 | 12.9 | 0.51 | 2025-06-25 | 6 | 6 | CH3NH3PBI3 PEROVSKITE; SOLAR-CELLS; PHASE; PERFORMANCE; CATION; MICROSTRUCTURE; RECOMBINATION; SEGREGATION; STABILITY; EVOLUTION | Binary alloys; Defect states; Lead alloys; Lead compounds; Passivation; Perovskite; Rigid structures; Antiphase boundaries; Defect state; Grain-boundaries; Halide perovskites; Rigid body; Self-passivation; Shallow defects; Tilt grain boundary; Grain boundaries | English | 2022 | 2022-05-26 | 10.1021/acs.jpclett.2c01123 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | The Photocycle of Bacteriophytochrome Is Initiated by Counterclockwise Chromophore Isomerization | Photoactivation of bacteriophytochrome involves acis-trans photoisomerization of a biliverdin chromophore, butneither the precise sequence of events nor the direction of theisomerization is known. Here, we used nonadiabatic moleculardynamics simulations on the photosensory protein dimer toresolve the isomerization mechanism in atomic detail. In oursimulations the photoisomerization of the D ring occurs in thecounterclockwise direction. On a subpicosecond time scale, thephotoexcited chromophore adopts a short-lived intermediate witha highly twisted configuration stabilized by an extended hydrogen-bonding network. Within tens of picoseconds, these hydrogenbonds break, allowing the chromophore to adopt a more planarconfiguration, which we assign to the early Lumi-R state. Theisomerization process is completed via helix inversion of thebiliverdin chromophore to form the late Lumi-R state. The mechanistic insights into the photoisomerization process are essential tounderstand how bacteriophytochrome has evolved to mediate photoactivation and to engineer this protein for new applications. | Morozov, Dmitry; Modi, Vaibhav; Mironov, Vladimir; Groenhof, Gerrit | Univ Jyvaskyla, Nanosci Ctr, Jyvaskyla 40014, Finland; Univ Jyvaskyla, Dept Chem, Jyvaskyla 40014, Finland; Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea | ; Morozov, Dmitry/Q-2433-2017; Mironov, Vladimir/I-4712-2012 | 26536517500; 57191625723; 16203310700; 6506118299 | gerrit.x.groenhof@jyu.fi; | JOURNAL OF PHYSICAL CHEMISTRY LETTERS | J PHYS CHEM LETT | 1948-7185 | 13 | 20 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2022 | 5.7 | 12.9 | 1.19 | 2025-06-25 | 15 | 14 | PHOTOACTIVE YELLOW PROTEIN; CYANOBACTERIAL PHYTOCHROME CPH1; FLUORESCENT PROTEINS; STATE; PHOTOCHEMISTRY; PHOTORECEPTORS; DYNAMICS | Bacterial Proteins; Biliverdine; Hydrogen Bonding; Isomerism; Molecular Dynamics Simulation; Dimers; Hydrogen bonds; Isomerization; Isomers; Molecular dynamics; Optical resonators; Proteins; bacterial protein; biliverdin; Cis-trans photoisomerization; Counterclockwise directions; D-rings; Hydrogen bonding network; Nonadiabatic molecular dynamics; Photo activations; Photocycles; Sequence of events; Subpicosecond time scale; chemistry; hydrogen bond; isomerism; metabolism; molecular dynamics; Chromophores | English | 2022 | 2022-05-26 | 10.1021/acs.jpclett.2c00899 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A fundamental study of CO2 capture and CH4 production in a rapid cyclic system using nickel-lithium-silicate as a catal-sorbent | Sustainable CH4 production in CO2 green technology has been recently proposed to mitigate climate emergency and to utilize waste sources of CO2 in the industry, reducing the total thermal energy. However, earlier studies have focused primarily on the CO2 capture capacity and CH4 productivity, and have not elucidated the kinetics of CO2 capture and CH4 production. Here, we prepared a nickel-lithium-silicate (Ni/LS) catal-sorbent by solid state reaction, which is one of the highly scalable synthesis method. The Ni/LS shows the high CO2 capture capacity and CH4 productivity with multicycle stability at 550 degrees C and the carbonated Ni/LS catal-sorbent is regenerated completely at lower temperature than that of conventional decarbonation. Moreover, the decarbonation rate of the carbonated Ni/LS catal-sorbent is enhanced significantly according to the Le Chatelier's principle, enabling the excellent working CO2 capture capacity and CH4 productivity with multicycle stability in a rapid cyclic system without temperature or pressure swings. | Jo, Seongbin; Lee, Jong Heon; Kim, Tae Young; Woo, Jin Hyeok; Ryu, Ho-Jung; Hwang, Byungwook; Lee, Soo Chool; Kim, Jae Chang; Gilliard-AbdulAziz, Kandis Leslie | Univ Calif Riverside, Dept Chem & Environm Engn, Riverside, CA 92521 USA; Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem Engn, Daegu 41566, South Korea; Korea Inst Energy Res, Daejeon 34129, South Korea; Univ Calif Riverside, Dept Mat Sci & Engn, Riverside, CA 92521 USA | ; Ryu, Ho-Jung/AAV-3451-2020; Jo, SeongBin/MFJ-9000-2025 | 57190754848; 57218697910; 57208461628; 57215492471; 7202277238; 44461423600; 8524020100; 55382762400; 57200598917 | soochool@knu.ac.kr;kjchang@knu.ac.kr;klabdulaziz@engr.ucr.edu; | FUEL | FUEL | 0016-2361 | 1873-7153 | 311 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 1.8 | 2025-06-25 | 22 | 23 | Sustainable CH4 production; CO2 green technology; Direct methanation; Nickel-lithium-silicate; Le Chatelier's principle; Rapid cyclic system | DUAL FUNCTION MATERIALS; MGO-BASED SORBENTS; WATER-GAS SHIFT; CARBON-DIOXIDE; CONVERSION; METHANATION; REGENERATION; TEMPERATURE; NITRATES; SORPTION | CO<sub>2</sub> green technology; Direct methanation; Le Chatelier's principle; Nickel-lithium-silicate; Rapid cyclic system; Sustainable CH<sub>4</sub> production | Environmental technology; Lithium compounds; Nickel compounds; Productivity; Silicates; Solid state reactions; Sorbents; Sorption; CH 4; CO2 green technology; Cyclic systems; Direct methanation; Green technology; Le chatelier's principles; Lithium silicates; Nickel-lithium-silicate; Rapid cyclic system; Sustainable CH4 production; Carbon dioxide | English | 2022 | 2022-03-01 | 10.1016/j.fuel.2021.122602 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bioengineered Co-culture of organoids to recapitulate host-microbe interactions | The recent spike in the instances of complex physiological host-microbe interactions has raised the demand for developing in vitro models that recapitulate the microbial microenvironment in the human body. Organoids are steadily emerging as an in vitro culture system that closely mimics the structural, functional, and genetic features of complex human organs, particularly for better understanding host-microbe interactions. Recent advances in organoid culture technology have become new avenues for assessing the pathogenesis of symbiotic interactions, pathogen-induced infectious diseases, and various other diseases. The co-cultures of organoids with microbes have shown great promise in simulating host-microbe interactions with a high level of complexity for further advancement in related fields. In this review, we provide an overview of bioengineering approaches for microbe -co-cultured organoids. Latest developments in the applications of microbe-co-cultured organoids to study human physiology and pathophysiology are also highlighted. Further, an outlook on future research on bioengineered organoid co-cultures for various applications is presented. | Kim, Min Beom; Hwangbo, Soonho; Jang, Sungho; Jo, Yun Kee | Kyungpook Natl Univ, Sch Convergence, Dept Biomed Convergence Sci & Technol, Daegu 41566, South Korea; Gyeongsang Natl Univ, Dept Chem Engn, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept Mat Engn & Convergence Technol, Jinju 52828, South Korea; Incheon Natl Univ, Coll Life Sci & Bioengn, Div Bioengn, Incheon 22012, South Korea; Incheon Natl Univ, Dept Bioengn & Nanobioengn, Incheon 22012, South Korea; Incheon Natl Univ, Res Ctr Bio Mat & Proc Dev, Incheon 22012, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu 41944, South Korea | ; Hwangbo, Soonho/AAA-2827-2021 | 57789506400; 56392750600; 57199982388; 56123757800 | ykjo@knu.ac.kr; | MATERIALS TODAY BIO | MATER TODAY BIO | 2590-0064 | 16 | SCIE | ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS | 2022 | 8.2 | 13.0 | 0.75 | 2025-06-25 | 24 | 23 | Organoids; Co -culture model; Host -microbe interaction; Human physiology; Pathophysiology | CHLAMYDIA-TRACHOMATIS INFECTION; CLOSTRIDIUM-DIFFICILE TOXIN; ZIKA VIRUS; HELICOBACTER-PYLORI; ROTAVIRUS INFECTION; NEURAL PROGENITORS; CEREBRAL ORGANOIDS; MODEL; DISEASE; CELLS | Co-culture model; Host-microbe interaction; Human physiology; Organoids; Pathophysiology | Bacteria; Physiology; Co-culture model; Co-cultures; Culture modelling; Host-microbe interaction; Human bodies; Human physiology; In-vitro models; Microenvironments; Organoids; Pathophysiology; Physiological models | English | 2022 | 2022-12 | 10.1016/j.mtbio.2022.100345 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Emerging trends and nanotechnology advances for sustainable biogas production from lignocellulosic waste biomass: A critical review | Biogas production is the most important requirement for substituting fossil fuel in an eco-friendly manner. Though several routes of renewable energy sources are available, biogas generation occupies an irreplaceable position due to huge lignocellulosic biomass availability. Hence, researchers worldwide are attempting on a large scale to develop low-cost and sustainable biogas production for use in transportation, electricity and heat generation. Studies have identified various lignocellulosic resources as raw materials for biogas production. In this context, the nanotechnological intervention and emerging strategies for sustainable biogas production have greater potential to meet the requirements in terms of cost and environmental safety. Biogas generation in oxygen-free digesting processes can be boosted by utilizing customized nanoparticles to dose ions. To maximize biogas generation, it is possible to use unstable nanoparticles, but they can be tailored to provide the ions in a regulated manner. Anaerobic conditions are ideal for nanoparticles dissolution and supply to anaerobic microbes responsible for the organic material breakdown, which is a job that is well-suited to them. However, there exists a large gap in providing up-to-date information on emerging nanotechnology research in biogas generation from enormous uncommitted lignocellulosic resources. To fulfill the lacuna, the present review critically elucidates the existing methods, nanotechnological intervention, emerging and advanced trends in biogas production to benefit society. | Govarthanan, Muthusamy; Manikandan, Sivasubramanian; Subbaiya, Ramasamy; Krishnan, Radhakrishnan Yedhu; Srinivasan, Subramanian; Karmegam, Natchimuthu; Kim, Woong | Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Dept Biotechnol, Chennai 602105, Tamil Nadu, India; Copperbelt Univ, Sch Math & Nat Sci, Dept Biol Sci, Jambo Dr,POB 21692, Kitwe, Zambia; Amal Jyothi Coll Engn, Dept Food Technol, Kottayam 686518, Kerala, India; Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Dept Biomed Engn, Chennai 602105, Tamil Nadu, India; Govt Arts Coll Autonomous, Dept Bot, Salem 636007, Tamil Nadu, India | Govarthanan, Muthusamy/C-1491-2014; Subbaiya, R/AAR-2948-2021; Krishnan, Radhakrishnan/K-7885-2016; S, Manikandan/GZM-7135-2022; S, Dr. Srinivasan/AAC-1534-2022; AVS, Srini/ADT-1145-2022; Muthusamy, Govarthanan/C-1491-2014; Karmegam, Natchimuthu/J-4745-2019; Natchimuthu, Karmegam/J-4745-2019 | 54881927600; 55213168500; 55263515700; 57198186588; 57226265799; 6506043230; 55581636400 | gova.muthu@gmail.com;elshine@knu.ac.kr; | FUEL | FUEL | 0016-2361 | 1873-7153 | 312 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 6.12 | 2025-06-25 | 61 | 79 | Biogas; Lignocellulose; Methanogens; Nanoadditives; Pretreatment process | ANAEROBIC-DIGESTION; METHANE PRODUCTION; THERMOCHEMICAL PRETREATMENT; CO-DIGESTION; OPTIMIZATION; ENHANCEMENT; DESIGN; BIOBUTANOL; HYDROGEN; REACTOR | Biogas; Lignocellulose; Methanogens; Nanoadditives; Pretreatment process | Biogas; Biomass; Fossil fuels; Nanoparticles; Sustainable development; Biogas generation; Biogas production; Critical review; Eco-friendly; Emerging trends; Lignocellulosic resources; Lignocellulosic wastes; Nanoadditives; Pretreatment process; Waste biomass; Lignocellulose | English | 2022 | 2022-03-15 | 10.1016/j.fuel.2021.122928 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Evaluation of iron-based alloy nanocatalysts for the electrooxidation of ethylene glycol in membraneless fuel cells | The development of efficient and sustainable electrocatalysts for power conversion devices that generate electricity is essential to alleviate the energy crisis. In this work, carbon-supported iron-group alloy nanocatalysts composed of iron, cobalt and nickel with different atomic ratios were synthesized by a two-step reduction method. The morphology and composition of synthesized alloy nanocatalysts were studied by various physicochemical characterization techniques such as X-ray diffraction, transmission electron microscopy, and energy dispersive X-ray spectroscopy. The X-ray diffraction studies showed a well-mixed solid-solution structure rather than a phase-separated structure for the ternary metals. Furthermore, transmission electron micrographs revealed that carbon-supported iron alloy samples displayed a homogenous dispersion with a particle size of 13-30 nm. The results of electrochemical analyses such as cyclic voltammetry, linear sweep voltammetry and chronoamperometry showed that nickel-containing alloy samples exhibited significantly higher electrochemical activity than non-nickel-alloyed samples. In a single membraneless fuel cell, the alloy nanocatalysts were tested as anodes for the electro-oxidation of ethylene glycol to evaluate their durability and effectiveness at room temperature. The single cell test revealed that the performance of the ternary anode is superior to that of their counterparts, which is consistent with the results of cyclic voltammetry and chronoamperometry. The fact that nickel stimulates cobalt sites to oxidize iron to iron oxyhydroxides at lower overpotential is an important factor contributing to the improved performance of nickel-containing ternary alloy catalysts. | Gayathri, A.; Kiruthika, S.; Selvarani, V; AlSalhi, Mohamad S.; Devanesan, Sandhanasamy; Kim, Woong; Muthukumaran, B. | Univ Madras, Presidency Coll Autonomous, Dept Chem, Chennai 600005, Tamil Nadu, India; SRM Inst Sci & Technol, Coll Engn & Technol, Dept Chem Engn, Chennai 603203, Tamil Nadu, India; King Saud Univ, Coll Sci, Dept Phys & Astron, POB 2455, Riyadh 11451, Saudi Arabia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Selvarani, V/GMW-7523-2022; Devanesan, Dr. Sandhanasamy/ABH-3378-2021; Devanesan, Sandhanasamy/ABH-3378-2021 | 57216655662; 56430997500; 55151093500; 10440259800; 55279721800; 55581636400; 6603252722 | dr.muthukumaran@yahoo.com; | FUEL | FUEL | 0016-2361 | 1873-7153 | 321 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 1.02 | 2025-06-25 | 13 | 13 | Ethylene glycol oxidation; Iron-cobaltnickel; Membrane-less fuel cell; Electrocatalyst; Sodium perborate | OXYGEN-EVOLUTION; CARBON SHELL; ELECTROCHEMICAL OXIDATION; FE; NANOPARTICLES; PERFORMANCE; ELECTROCATALYSTS; CATALYSTS; METHANOL; COMPOSITES | Electrocatalyst; Ethylene glycol oxidation; Iron-cobalt–nickel; Membrane-less fuel cell; Sodium perborate | Anodes; Chronoamperometry; Cyclic voltammetry; Durability; Electrocatalysts; Electrooxidation; Energy dispersive spectroscopy; Ethylene; Fuel cells; High resolution transmission electron microscopy; Iron compounds; Nanocatalysts; Particle size; Particle size analysis; Polyols; Sodium compounds; Ternary alloys; X ray diffraction; Cobalt-nickel; Electrocatalyst; Electrooxidations; Ethylene glycol oxidation; Iron-cobalt; Iron-cobalt–nickel; Membrane-less fuel cell; Membraneless fuel cell; Nano-catalyst; Sodium perborate; Ethylene glycol | English | 2022 | 2022-08-01 | 10.1016/j.fuel.2022.124059 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | General mechanism and mitigation for strong adhesion of frozen oil sands on solid substrates | Oil sands adhered on truck bed reduce transport capacity of the truck, require manual cleaning, and create hurdles for automated surface mining. Study on the adhesion properties of oil sands to solid substrates is important to minimize the fouling of substrates during mining operation. In this work, we study the influence of hydrophobicity and mechanical properties of the substrates on the adhesion strength of frozen oil sands. By using an adhesion force apparatus with temperature control, we measure the adhesion strength of both ice and frozen oil sands on six types of substrates with water contact angle from ~20 to ~130 and Young's modulus from a few MPa to 300 GPa. A clear linear correlation between the adhesion strength of pure ice and that of frozen oil sands is observed. Furthermore, the adhesion strength increases with the load on the oil sands sample, and reaches a plateau at ~450 kPa. The maximum adhesion strength may be due to the limit of particle packing of oil sands. We also demonstrate that spray coating of anti-freezing liquids is effective for the mitigation of the adhesion of frozen oil sands. Substrates coated with various anti-freezing liquids showed undetectable oil sands adhesion strength at -20 ? with 0.06 MPa of load. The study on oil sands adhesion and potential fouling mitigation method may provide a potential solution to industries looking to reduce fouling of surfaces by frozen granular matter. | Yang, Qimeng; Moradpour, Nikoo; You, Jae Bem; Wang, Dehui; Tian, Boran; Sun, Shaofeng; Liu, Qi; Deng, Xu; Daniel, Dan; Zhang, Xuehua | Univ Alberta, Dept Chem & Mat Engn, Edmonton, AB T6G 1H9, Canada; Kyungpook Natl Univ, Dept Chem Engn, Daegu 41566, South Korea; Univ Elect Sci & Technol China, Inst Fundamental & Frontier Sci, Ctr Mat Surface Sci, Chengdu 610054, Peoples R China; Imperial Oil, Calgary, AB T2C 4P3, Canada; ASTAR, Inst Mat Res & Engn IMRE, Singapore 138634, Singapore | Zhang, Xuehua/G-1085-2010; dehui, wang/K-1302-2016; Yang, Qimeng/IWM-6186-2023; You, Jae/C-6211-2019; You, Jae Bem/C-6211-2019; Daniel, Dan/M-5386-2013; Deng, Xu/G-4589-2011; Daniel, Dan/N-2836-2019 | 57485287800; 57218341391; 55619455300; 57208004522; 57485287900; 57485076000; 57816810100; 36197988900; 56694017100; 8918489500 | jb.you@knu.ac.kr;xuehua.zhang@ualberta.ca; | FUEL | FUEL | 0016-2361 | 1873-7153 | 325 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 0.24 | 2025-06-25 | 3 | 3 | Adhesion; Hydrophobicity; Softness; Frozen oil sands; Anti-freezing liquids | LOW ICE ADHESION; EXTRACTION; BITUMEN; DESIGN; POLYDIMETHYLSILOXANE; WETTABILITY | Adhesion; Anti-freezing liquids; Frozen oil sands; Hydrophobicity; Softness | Contact angle; Elastic moduli; Freezing; Hydrophobicity; Liquids; Sand; Adhesion properties; Anti-freezing; Anti-freezing liquid; Freezing liquids; Frozen oil sand; Manual cleaning; Softness; Solid substrates; Transport capacity; Truck beds; Adhesion | English | 2022 | 2022-10-01 | 10.1016/j.fuel.2022.124797 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | How to control and manage vessels' ballast water: The perspective of Korean shipping companies | Selecting the efficiency of the technologies and reasonable strategies to ensure compliance with stricter international regulations on ballast water are issues that need to be focused on. Particularly, in a period of economic decline, these auxiliary costs due to the regulation enforcement may be a significant burden for vessel operators, especially those with old vessels, where the maintenance costs are high. Because of these new limitations on marine transport, which has been regarded as a more eco-friendly alternative than other forms of transportation, maritime policymakers in each country may need to take prudence in making policy decisions. Nevertheless, few studies have evaluated the existing alternatives that can decrease the invasion risk due to ballast water release, and fewer have developed a general system for determining the optimal technology. Accordingly, in this study, an empirical analysis focusing on the alternatives of ballast treatment systems considered by Korean shipping companies is performed. As the main approach, surveys and interviews are conducted to examine how Korean shipping companies' real response directions help cope with the International Convention for the Control and Management of Ships' Ballast Water and Sediments. The results indicate that, among 15 sub-criteria of considerations for response by Korean shipping companies, approval is the most considerable factor. In addition, through the description analysis of Korean shipping companies, a difference in the recognition and response direction according to firm size and vessels' age was observed. This study's findings provides valuable suggestions for designing government policies for the shipping industry's ballast water management. | Kim, A-Rom; Lee, Sung-Woo; Seo, Young-Joon | Korea Maritime Inst, Logist & Maritime Ind Res Dept, Busan, South Korea; Kyungpook Natl Univ, Sch Econ & Trade, 80 Daehak Ro, Daegu 41566, South Korea | Seo, Young-Joon/AAY-6105-2021 | 57202101135; 55716353700; 56999695700 | arkim@kmi.re.kr;waterfront@kmi.re.kr;y.seo@knu.ac.kr; | MARINE POLICY | MAR POLICY | 0308-597X | 1872-9460 | 138 | SSCI | ENVIRONMENTAL STUDIES;INTERNATIONAL RELATIONS | 2022 | 3.8 | 13.0 | 1.59 | 2025-06-25 | 9 | 13 | BWMC; Ballast water; Ballast water treatment system; Response direction; Korean shipping company | RISK-ASSESSMENT; NATURAL-POPULATIONS; TREATMENT SYSTEMS; SELECTION; RADIATION; CHALLENGES; EXEMPTIONS; EFFICACY; PLANKTON; POLICY | Ballast water; Ballast water treatment system; BWMC; Korean shipping company; Response direction | Korea; ballast water; maritime transportation; shipping; strategic approach; vessel; water treatment | English | 2022 | 2022-04 | 10.1016/j.marpol.2022.105007 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Nanoarchitectonics of polyaniline-derived porous carbons for efficient adsorptive denitrogenation of liquid fuel | Highly porous polyaniline-derived carbons (pDCs) were used as adsorbents to adsorb/remove hazardous organonitrogens (ONs) from liquid fuel for the first time. The nitrogen-rich pDCs were obtained via the carbonization of polyaniline (pANI) under an inert atmosphere. Further, the pDCs were activated in the presence of KOH (as a chemical activating agent) at different pyrolysis temperatures (600 to 800 degrees C) to increase the porosity or surface area of the pDCs. One pDC prepared at 700 degrees C (named pDC-700) showed very efficient adsorptions of representative ONs (indole and quinoline) from liquid fuel. The pDC-700 had a maximum adsorption capacity of 458 mg/g of quinoline which is the highest among the reported values with carbon-based adsorbents. The maximum adsorption capacity of the same adsorbent for the adsorption of indole (385 mg/g) was also very competitive against other carbonaceous adsorbents. The high adsorption capacities of the pDC-700 could be interpreted by a synergistic effect of an efficient hydrogen bonding (between the heteroatoms of pDC-700 and the adsorbates) and high microporosity of the adsorbent (SA(BET) > 2000 m(2)/g). In addition, a simple solvent washing could regenerate the pDC-700 for the successive utilization in adsorptions effectively. | Khan, Nazmul Abedin; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; East West Univ, Dept Math & Phys Sci, Dhaka 1212, Bangladesh | Jhung, Sung/AAO-6683-2021 | 35170042700; 6701659467 | nazmul.ch@ewubd.edu;sung@knu.ac.kr; | FUEL | FUEL | 0016-2361 | 1873-7153 | 320 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 0.63 | 2025-06-25 | 8 | 8 | Adsorption; Hydrogen bonding; Liquid fuel; Organonitrogens; Polyaniline-derived carbon | OXYGEN FUNCTIONAL-GROUPS; METAL-ORGANIC FRAMEWORK; NITROGEN-COMPOUNDS; REMARKABLE ADSORBENT; SELECTIVE ADSORPTION; HYDROCARBON STREAMS; HETEROCYCLIC SULFUR; NANOPOROUS CARBONS; REMOVAL; PERFORMANCE | Adsorption; Hydrogen bonding; Liquid fuel; Organonitrogens; Polyaniline-derived carbon | Carbon; Carbonization; Gas adsorption; Hydrogen; Liquids; Polyaniline; Polycyclic aromatic hydrocarbons; Porous materials; Potassium hydroxide; Activating agents; Adsorption capacities; Adsorptive denitrogenation; Carbonisation; Derived carbons; Inert atmospheres; Organonitrogen; Polyaniline-derived carbon; Pyrolysis temperature; Surface area; Hydrogen bonds | English | 2022 | 2022-07-15 | 10.1016/j.fuel.2022.123970 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Nanomaterials for transforming barrier properties of lignocellulosic biomass towards potential applications-A review | Wood with many of its useful components builds and supports the flora, besides having a commercial signifi-cance. Coatings on the wood are used to preserve it from degradation by physical, chemical, and biological attacks, and this attribute is considered as a barrier property. Latter due to commercialization, the non-permeability to volatile substances and gases is also considered as a part of barrier property. Renewable and biodegradable cellulose derivatives and lignin have been known for their porosity, hydrophilicity, and barrier property. Hemicellulose and lignin are not preferred much when compared to cellulose for many commercial applications. However, the onset of nanotechnology has made utilization of these waste or non-treatable by-products of lignocellulosic biomass as potential barrier coatings in the food and paper industry. Moreover, the weakening process of lignocellulosic biomass by microbial enzymes or microbes conjointly with nanoparticles decreases the barrier property which could be utilized for biofuel applications. Nanomaterial conjugated hemicellulose has exhibited the lowest oxygen and vapor permeability level of 0.1799 cm(3).mu m/m(2).d.kPa and 2.75 x 10 (11) g/m.s respectively, whereas lignin seems to have long term moisture control for up to 189%. The current review highlights the progress in transforming the lignocellulosic biomass derivatives for food, paper, and biofuel industrial applications. | Dey, Nibedita; Vickram, Sundaram; Thanigaivel, Sundaram; Subbaiya, Ramasamy; Kim, Woong; Karmegam, Natchimuthu; Govarthanan, Muthusamy | Saveetha Inst Med & Tech Sci SIMATS, Saveetha Sch Engn, Dept Biotechnol, Chennai 602105, Tamil Nadu, India; Copperbelt Univ, Sch Math & Nat Sci, Dept Biol Sci, Jambo Dr,POB 21692, Kitwe, Zambia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Govt Arts Coll Autonomous, Dept Bot, Salem 636007, Tamil Nadu, India | Karmegam, Natchimuthu/J-4745-2019; Natchimuthu, Karmegam/J-4745-2019; Govarthanan, Muthusamy/C-1491-2014; Subbaiya, R/AAR-2948-2021; S, Vickram/ABG-9459-2020; Sundaram, Thanigaivel/H-2860-2016; dey, nibedita/AAG-6776-2021; Muthusamy, Govarthanan/C-1491-2014; S, Thanigaivel/H-2860-2016 | 57216549253; 55257689800; 55624925900; 55263515700; 55581636400; 6506043230; 54881927600 | kanishkarmegam@gmail.com;gova.muthu@gmail.com; | FUEL | FUEL | 0016-2361 | 1873-7153 | 316 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 4.94 | 2025-06-25 | 37 | 63 | Barrier property; Biofuel; Food industry; Lignocellulose; Nanomaterials; Paper industry | GALACTOGLUCOMANNAN HEMICELLULOSE; FUNCTIONAL-PROPERTIES; ANAEROBIC-DIGESTION; TENSILE PROPERTIES; OXYGEN BARRIER; UV-BLOCKING; LIGNIN; CELLULOSE; FILMS; FIBER | Barrier property; Biofuel; Food industry; Lignocellulose; Nanomaterials; Paper industry | Barrier Properties; Biomass; Coatings; Enzymes; Moisture Control; Biomass; Coatings; Enzymes; Lignin; Mechanical permeability; Moisture control; Nanostructured materials; Paper and pulp industry; Barrier properties; Biological attack; Cellulose -derivatives; Chemical and biologicals; Commercialisation; Food industries; Paper industries; Physical attacks; Volatile gas; Volatile substances; Lignocellulose | English | 2022 | 2022-05-15 | 10.1016/j.fuel.2022.123444 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Nosocomial outbreak of severe fever with thrombocytopenia syndrome among healthcare workers in a single hospital in Daegu, Korea | Background: In August 2020, 17 healthcare workers (HCWs) were simultaneously diagnosed with severe fever with thrombocytopenia syndrome (SFTS) at a university hospital in Daegu, Republic of Korea. Methods: An epidemiologic investigation using questionnaires was conducted for all suspected HCWs who had viral infection symptoms or who had the possibility of exposure to the index patient. Results: A total of 17 HCWs infected with the SFTS virus (SFTSV) (28.8%) were identified among the 59 HCWs who had contact with the patient. Operating a bag valve mask during cardiopulmonary resusci-tation (CPR) (OR 7.50, 95% CI 1.75-41.07), cardiac massage during CPR (OR 12.00, 95% CI 1.76-241.94), exposure to the patient's body fluids (OR 7.43, 95% CI 1.91-34.69), and shorter individual hospital work experience periods (OR 6.79, 95% CI 1.70-32.10) were significantly associated with SFTS infection in the univariate analysis. However, exposure to body fluids was found to be the only statistically significant risk factor when multivariate analysis was conducted (OR 6.27. 95% CI 1.23-42.81, p = 0.036). Conclusions: This finding illustrates the importance of wearing appropriate personal protective equipment in treatment areas and when conducting any medical procedures, including CPR for patients with SFTS, and any procedure that involves potential exposure to body fluids.

| ○ | ○ | Article | Novel manganese oxide decorated polyaniline/graphitic carbon nitride nanohybrid material for efficient supercapacitor application | Supercapacitors are gaining popularity as a component in energy storage systems due to their quick charge/ discharge rates and high specific power. A facile method is introduced in this research to fabricate a novel ternary nanocomposite-based manganese oxide decorated on polyaniline/graphitic carbon nitride (PANI-GCN) nano-hybrid modified graphite sheet (GC) electrode via the electrochemical deposition method. As-prepared nano-composite modified electrode morphology, elemental analysis, surface functionalities studies, and crystalline behavior are proved using SEM, Energy Dispersive Analysis, FT-IR, and XRD techniques. The electrochemical measurements are obtained by CV, GCD, and EIS. For Bare GS, PANI, and PANI-GCN, the solution resistance (Rs) that gauges the ionic conductivity across the electrolyte, was measured to be 60.57 omega, 7.28 omega, and 6.19 omega, respectively. A greater specific capacitance of 318 F/g at 1 A/g was displayed by the developed MnO2@PANI-GCN electrode and lower charge transfer resistance over the PANI and PANI-GCN electrodes. Furthermore, the proposed electrode has shown the capacitive retention of 80.62% up to 1000 cycles. These results indicate that the ternary nanocomposite MnO2@PANI-GCN shows significant electrochemical properties towards energy storage applications. | Chahal, Priyanka; Madaswamy, Suba Lakshmi; Lee, Soo Chool; Wabaidur, Saikh Mohammad; Dhayalan, Vasudevan; Ponnusamy, Vinoth Kumar; Dhanusuraman, Ragupathy | Natl Inst Technol Puducherry, Dept Chem, Nano Electrochem Lab NEL, Karaikal 609609, India; Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; King Saud Univ, Coll Sci, Dept Chem, Riyadh 11451, Saudi Arabia; Kaohsiung Med Univ, Dept Med & Appl Chem, Kaohsiung 807, Taiwan; Kaohsiung Med Univ, Res Ctr Precis Environm Med, Kaohsiung 807, Taiwan; Kaohsiung Med Univ Hosp, Dept Med Res, Kaohsiung 807, Taiwan; Natl Inst Technol Puducherry, Dept Chem, Karaikal 609609, India | Ponnusamy, Vinoth Kumar/G-5540-2011; wabaidur, Saikh/Z-1450-2019; Chahal, Premjeet/G-5308-2013 | 57729174100; 57222147966; 8524020100; 24336563700; 20733920700; 51261449800; 23668492700 | kumar@kmu.edu.tw;ragu@nitpy.ac.in; | FUEL | FUEL | 0016-2361 | 1873-7153 | 330 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 2.98 | 2025-06-25 | 36 | 40 | Manganese oxide; Polyaniline; Graphitic carbon nitride; Electrodeposition; Supercapacitor | GRAPHITIC CARBON; GRAPHENE OXIDE; ELECTRODE; HYBRID; COMPOSITE; ELECTROCATALYST; NANOCOMPOSITES; NANOSHEETS | Electrodeposition; Graphitic carbon nitride; Manganese oxide; Polyaniline; Supercapacitor | Carbon nitride; Charge transfer; Electrochemical deposition; Electrochemical electrodes; Electrolytes; Energy storage; Manganese oxide; Morphology; Nanocomposites; Oxides; Polyaniline; Reduction; Charge- discharge rate; Facile method; Graphitic carbon nitrides; Modified graphites; Nano-hybrid materials; Nanohybrids; Specific power; Storage systems; Supercapacitor application; Ternary nanocomposites; Supercapacitor | English | 2022 | 2022-12-15 | 10.1016/j.fuel.2022.125531 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Optimization of binary acids pretreatment of corncob biomass for enhanced recovery of cellulose to produce bioethanol | Lignocellulosic agricultural wastes are the most widely utilized resource for bioethanol production due to several advantages. Removal of hemicellulose and lignin is a prerequired step during bioethanol production from lignocellulosic biomass to upgrade cellulose recovery and the substrate porosity for saccharification. Chemical pretreatment of corncob was performed in the current research applying binary acids (H2SO4 + CH3COOH) in different ratios. The attained maximum removal of lignin and hemicellulose were 81.41 +/- 2.3% and 85.6 +/- 1.8%, respectively, with enhanced cellulose recovery of 93.5 +/- 1.3% at the optimum conditions of binary acids concentration (3%, v/v), biomass loading ratio (0.1 g/mL), pretreatment temperature (120 degrees C) and time (60 min). The SEM, FTIR and XRD results revealed the removal of hemicelluloses and lignin from the corncob biomass by binary acids pretreatment and confirmed a change in the crystallinity index of corncob biomass. Ethanol fermentation was accomplished at 30 degrees C at 200 rpm for 4 days with the hydrolysates using Saccharomyces cerevisiae and obtained a maximum bioethanol concentration of 24.6 mg/mL. This study demonstrates that binary acids pretreatment is an alternative approach for the pretreatment of lignocellulosic biomass. The optimized process conditions could also increase cellulose recovery and bioethanol yield. | Selvakumar, P.; Adane, A. A.; Zelalem, T.; Hunegnaw, B.

| ○ | ○ | Article | Oxidative modification of metal-organic framework-derived carbon: An effective strategy for adsorptive elimination of carbazole and benzonitrile | The elimination of nitrogen-containing compounds (NCCs), such as carbazole (CARB) and benzonitrile (BENZ), from fuels is essential before use. In this study, an efficient adsorbent was prepared through oxidative modification of metal-organic framework (MOF)-derived carbon to effectively remove NCCs from fuel. The prepared adsorbent, oxidized MOF-derived carbon (OMDC), showed noticeable performance in removing NCCs from model fuel. OMDC showed 4-and 26-times the adsorption capacity for the removal of CARB and BENZ, respectively, compared with that of activated carbon. Moreover, OMDC showed the highest adsorption capacity for CARB and BENZ removal compared with any adsorbent reported thus far. The adsorption process could be explained by hydrogen bonding based on the presence of many hydrogen donor and acceptor sites on the developed adsorbent. Furthermore, the adsorbent could be reused several times for NCCs adsorption after simple ethanol washing. Therefore, OMDC is a potential adsorbent for the elimination of NCCs from fuels. | Mondol, Md Mahmudul Hassan; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Hassan Mondol, Md Mahmudul/AAM-8718-2021; Jhung, Sung/AAO-6683-2021 | 57217989090; 6701659467 | sung@knu.ac.kr; | FUEL | FUEL | 0016-2361 | 1873-7153 | 307 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL | 2022 | 7.4 | 13.0 | 1.49 | 2025-06-25 | 21 | 19 | Adsorption; Denitrogenation; MOF-derived carbon; Oxidation; Removal | NITROGEN-CONTAINING COMPOUNDS; DOPED POROUS CARBONS; REMARKABLE ADSORBENT; FUNCTIONAL-GROUPS; MODEL FUELS; BIO-OIL; DENITROGENATION; REMOVAL; DESULFURIZATION; MICROALGAE | Adsorption; Denitrogenation; MOF-derived carbon; Oxidation; Removal | Activated carbon; Crystalline materials; Fuels; Hydrogen; Hydrogen bonds; Organometallics; Oxidation; Polycyclic aromatic hydrocarbons; Removal; Adsorption capacities; Benzonitriles; Denitrogenation; Derived carbons; High adsorption capacity; Metal-organic framework-derived carbon; Metal-organic-frameworks; Model fuels; Oxidative modification; Performance; Adsorption | English | 2022 | 2022-01-01 | 10.1016/j.fuel.2021.121764 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
