| ○ | ○ | Article | CO2 to Value-Added Chemicals: Synthesis and Performance of Mono- and Bimetallic Nickel-Cobalt Nanofiber Catalysts | In an epoch dominated by escalating concerns over climate change and looming energy crises, the imperative to design highly efficient catalysts that can facilitate the sequestration and transformation of carbon dioxide (CO2) into beneficial chemicals is paramount. This research presents the successful synthesis of nanofiber catalysts, incorporating monometallic nickel (Ni) and cobalt (Co) and their bimetallic blend, NiCo, via a facile electrospinning technique, with precise control over the Ni/Co molar ratios. Application of an array of advanced analytical methods, including SEM, TGA-DSC, FTIR-ATR, XRD, Raman, XRF, and ICP-MS, validated the effective integration and homogeneous distribution of active Ni/Co catalysts within the nanofibers. The catalytic performance of these mono- and bimetallic Ni/Co nanofiber catalysts was systematically examined under ambient pressure conditions for CO2 hydrogenation reactions. The bimetallic NiCo nanofiber catalysts, specifically with a Ni/Co molar ratio of 1:2, and thermally treated at 1050 & DEG;C, demonstrated a high CO selectivity (98.5%) and a marked increase in CO2 conversion rate-up to 16.7 times that of monometallic Ni nanofiber catalyst and 10.8 times that of the monometallic Co nanofiber catalyst. This significant enhancement in catalytic performance is attributed to the improved accessibility of active sites, minimized particle size, and the strong Ni-Co-C interactions within these nanofiber structures. These nanofiber catalysts offer a unique model system that illuminates the fundamental aspects of supported catalysis and accentuates its crucial role in addressing pressing environmental challenges. | Schossig, John; Gandotra, Akash; Arizapana, Kevin; Weber, Daniel; Wildy, Michael; Wei, Wanying; Xu, Kai; Yu, Lei; Chimenti, Robert; Mantawy, Islam; Hyun, Dong Choon; Chen, Wenshuai; Zhang, Cheng; Lu, Ping | Rowan Univ, Dept Chem & Biochem, Glassboro, NJ 08028 USA; Long Isl Univ Post, Chem Dept, Brookville, NY 11548 USA; Rowan Univ, Dept Phys & Astron, Glassboro, NJ 08028 USA; Dept Civil & Environm Engn, Glassboro, NJ 08028 USA; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Northeast Forestry Univ, Key Lab Biobased Mat Sci & Technol, Minist Educ, Harbin 150040, Peoples R China | ; Mantawy, Islam/J-2065-2016; Lu, Ping/D-4724-2011 | 58420501800; 58419167100; 57845980700; 57644780100; 57846873700; 57219923324; 58419841800; 55488190100; 56495065100; 56626083600; 15834575400; 35304598300; 57213609342; 57195511292 | schoss43@students.rowan.edu;akash.gandotra@my.liu.edu;arizap27@students.rowan.edu;daniel.weber4@my.liu.edu;wildym28@rowan.edu;weiw8@rowan.edu;xuk4@students.rowan.edu;yu@rowan.edu;chimenti@rowan.edu;mantawy@rowan.edu;dong.hyun@knu.ac.kr;chenwenshuai@nefu.edu.cn;cheng.zhang@liu.edu;lup@rowan.edu; | CATALYSTS | CATALYSTS | 2073-4344 | 13 | 6 | SCIE | CHEMISTRY, PHYSICAL | 2023 | 3.8 | 41.3 | 0.91 | 2025-06-25 | 10 | 8 | nanofiber catalysts; CO2 hydrogenation; monometallic and bimetallic Ni; Co; supported catalysis; electrospinning | CARBON-FIBERS; THERMAL-DECOMPOSITION; ACETATE TETRAHYDRATE; HYDROGENATION; POLYACRYLONITRILE; NANOPARTICLES; DEGRADATION; SELECTIVITY; DEPOSITION; SCIENCE | CO<sub>2</sub> hydrogenation; electrospinning; monometallic and bimetallic Ni/Co; nanofiber catalysts; supported catalysis | English | 2023 | 2023-06 | 10.3390/catal13061017 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of the Ni-to-CaO Ratio on Integrated CO2 Capture and Direct Methanation | Direct methanation in an integrated CO2 capture and utilization system has recently gained considerable attention as a promising approach owing to its simplified process and lower requirement of total thermal energy as compared to conventional CO2 capture and utilization techniques. This study formulated macroporous structured Ni/CaO catal-sorbents by controlling the Ni-to-CaO ratio. The influence of this ratio on the CO2 capture (capacity and kinetics) and direct methanation performances (productivity and kinetics) was evaluated at 500 C-?. CO2 capture combined with direct methanation experiments revealed that 10Ni/CaO exhibited the best CO2 capture capacity, kinetics, and CH4 productivity with the thermal stability of Ni and CaO species. | Woo, Jin-Hyeok; Jo, Seongbin; Kim, Ju-Eon; Kim, Tae-Young; Son, Han-Dong; Ryu, Ho-Jung; Hwang, Byungwook; Kim, Jae-Chang; Lee, Soo-Chool; Gilliard-AbdulAziz, Kandis Leslie | Kyungpook Natl Univ, Dept Chem Engn, Daegu 41566, South Korea; Univ Calif Riverside, Dept Chem & Environm Engn, Riverside, CA 92521 USA; Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; Korea Inst Energy Res, Photovolta Lab, Daejeon 34129, South Korea; Univ Calif Riverside, Dept Mat Sci & Engn, Riverside, CA 92521 USA | ; Ryu, Ho-Jung/AAV-3451-2020; Kim, Yu/L-8480-2017; Jo, SeongBin/MFJ-9000-2025 | 57215492471; 57190754848; 58417827600; 57208461628; 58307056400; 7202277238; 44461423600; 55382762400; 8524020100; 57200598917 | wjh8865@knu.ac.kr;sjo016@ucr.edu;lawliet@knu.ac.kr;tyoung0218@knu.ac.kr;coma133he@knu.ac.kr;hjryu@kier.re.kr;hbw@kier.re.kr;kjchang@knu.ac.kr;soochool@knu.ac.kr;klabulaziz@engr.ucr.edu; | CATALYSTS | CATALYSTS | 2073-4344 | 13 | 8 | SCIE | CHEMISTRY, PHYSICAL | 2023 | 3.8 | 41.3 | 0.91 | 2025-06-25 | 10 | 8 | ICCU; direct methanation; Ni/CaO ratio; macroporous structure; Ni dispersion | CONVERSION; SORBENTS; SYSTEM; GAS | direct methanation; ICCU; macroporous structure; Ni dispersion; Ni/CaO ratio | English | 2023 | 2023-08 | 10.3390/catal13081174 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Engineering of GH11 Xylanases for Optimal pH Shifting for Industrial Applications | Endo-1,4-beta-xylanases belonging to the glycoside hydrolase (GH) 11 family hydrolyze the beta-1,4-glycosidic linkages in the xylan backbone to convert polymeric xylan into xylooligosaccharides. GH11 xylanases play an essential role in sugar metabolism and are one of the most widely used enzymes in various industries, such as pulp and paper, food and feed, biorefinery, textile, and pharmaceutical industries. pH is a crucial factor influencing the biochemical properties of GH11 xylanase and its application in bioprocessing. For the optimal pH shifting of GH11 xylanase in industrial applications, various protein engineering studies using directed evolution, rational engineering, and in silico approaches have been adopted. Here, we review the functions, structures, and engineering methods developed for the optimal pH shifting of GH11 xylanases. The various GH11 engineering techniques and key residues involved in pH shifting are discussed based on their crystal and modeled structure. This review provides an overview of recent advancements in the characterization and engineering of GH11 xylanases, providing a guide for future research in this field. | Kim, In Jung; Kim, Soo Rin; Bornscheuer, Uwe T.; Nam, Ki Hyun | Gyeongsang Natl Univ, Inst Agr & Life Sci, Dept Food Sci & Technol, Jinju 52828, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Univ Greifswald, Inst Biochem, Dept Biotechnol & Enzyme Catalysis, D-17487 Greifswald, Germany; Kookmin Univ, Coll Gen Educ, Seoul 02707, South Korea | Nam, Ki Hyun/N-6812-2019; Bornscheuer, Uwe/C-4612-2012; Kim, Soo Rin/X-2192-2019 | 57195531808; 36659584200; 7006947469; 13808340200 | ij0308@gnu.ac.kr;soorinkim@knu.ac.kr;uwe.bornscheuer@uni-greifswald.de;structure@kookmin.ac.kr; | CATALYSTS | CATALYSTS | 2073-4344 | 13 | 11 | SCIE | CHEMISTRY, PHYSICAL | 2023 | 3.8 | 41.3 | 0.63 | 2025-06-25 | 14 | 13 | xylanase; GH11; engineering; pH; tolerance; structure | BACILLUS-AMYLOLIQUEFACIENS XYLANASE; DIRECTED EVOLUTION; GEOBACILLUS-STEAROTHERMOPHILUS; CIRCULANS XYLANASE; PERFORMANCE; MECHANISMS; THERMOSTABILITY; ENZYMES | engineering; GH11; pH; structure; tolerance; xylanase | English | 2023 | 2023-11 | 10.3390/catal13111405 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | High Precision Hybrid Torque Control for 4-DOF Redundant Parallel Robots under Variable Load | As regards the impact and chattering of 4-DOF redundant parallel robots that occur under high-speed variable load operating conditions, this study proposed a novel control algorithm based on torque feedforward and fuzzy computational torque feedback hybrid control, which considered both the joint friction torque and the disturbance torque caused by the variable load. First of all, a modified dynamic model under variable load was established as follows: converting terminal load change to terminal centroid coordinate change, then mapping to the calculation of terminal energy, and lastly, establishing a dynamic model for each branch chain under variable load based on the Lagrange equation. Subsequently, torque feedforward was used to compensate for the friction torque and the disturbance torque caused by the variable load. Feedforward torques include friction torque and nonlinear disturbance torque under variable load. The friction torque is obtained by parameter identification based on the Stribeck friction model, while the nonlinear disturbance torque is obtained by real-time calculation based on the modified dynamic model under variable load. Finally, dynamic control of the robot under variable load was realized in combination with the fuzzy computational torque feedback control. The experimental and simulation results show that the motion accuracy of the fuzzy calculation torque feedback and torque feedforward control of the three drive joints of the robot under variable loads is 49.87%, 70.48%, and 50.37% lower than that of the fuzzy calculation torque feedback. Compared with pure torque feedback control, the speed stability of the three driving joints under fuzzy calculation torque feedback and torque feedforward control is 23.35%, 17.66%, and 25.04% higher, respectively. | Hu, Shengqiao; Liu, Houcai; Kang, Huimin; Ouyang, Puren; Liu, Zhicheng; Cui, Zhengjie | Hunan Univ Sci & Technol, Dept Mech Engn, Xiangtan 411201, Peoples R China; Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea; Toronto Metropolitan Univ, Dept Aerosp Engn, Toronto, ON M5B2K3, Canada | ; Hu, Shengqiao/GYJ-4392-2022; Ouyang, Puren/Y-9765-2018 | 57216397455; 57919613600; 33867598400; 57201551574; 59301479300; 57223237820 | hushengqiao@knu.ac.kr;houcailiu@163.com;xykanghm@163.com;pouyang@torontomu.ca; | ACTUATORS | ACTUATORS | 2076-0825 | 12 | 6 | SCIE | ENGINEERING, MECHANICAL;INSTRUMENTS & INSTRUMENTATION | 2023 | 2.2 | 41.3 | 0.73 | 2025-06-25 | 3 | 5 | redundant parallel robot; joint space; variable load; torque feedback; torque feedforward | MANIPULATOR | joint space; redundant parallel robot; torque feedback; torque feedforward; variable load | English | 2023 | 2023-06 | 10.3390/act12060232 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Improving the Stability of Ru-Doped Ni-Based Catalysts for Steam Methane Reforming during Daily Startup and Shutdown Operation | In this study, a Ru-doped Ni pellet-type catalyst was prepared to produce hydrogen via steam methane reforming (SMR). A small amount of Ru addition on the Ni catalyst improved Ni dispersion, thus affording a higher catalytic activity than that of the Ni catalyst. During the daily startup and shutdown (DSS) operations, the CH4 conversion of Ni catalysts significantly decreased because of Ni metal oxidation to NiAl2O4, which is not reduced completely at 700 & DEG;C. Conversely, the oxidized Ni species in the Ru-Ni catalyst can be reduced under SMR conditions because of H-2 spillover from the surface of Ru onto the surface of Ni. Consequently, the addition of a small quantity of Ru to the Ni catalyst can improve the catalytic activity and stability during the DSS operation. | Kim, Tae-Young; Lee, Jong-Heon; Jo, Seongbin; Kim, Jueon; Woo, Jin-Hyeok; Dhanusuraman, Ragupathy; Kim, Jae-Chang; Lee, Soo-Chool | Kyungpook Natl Univ, Res Inst Adv Energy Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem Engn, Daegu 41566, South Korea; Univ Calif Riverside, Dept Chem & Environm Engn, Riverside, CA 92521 USA; Natl Inst Technol Puducherry, Dept Chem, Nano Electrochem Lab NEL, Karaikal 609609, India | ; Kim, Yu/L-8480-2017; Jo, SeongBin/MFJ-9000-2025 | 57208461628; 57218697910; 57190754848; 58417827600; 57215492471; 23668492700; 55382762400; 8524020100 | tyoung0218@knu.ac.kr;rnswma123@knu.ac.kr;sjo016@ucr.edu;lawliet@knu.ac.kr;wjh8865@knu.ac.kr;ragu.nitpy@gmail.com;kjchang@knu.ac.kr;soochool@knu.ac.kr; | CATALYSTS | CATALYSTS | 2073-4344 | 13 | 6 | SCIE | CHEMISTRY, PHYSICAL | 2023 | 3.8 | 41.3 | 0.8 | 2025-06-25 | 5 | 7 | Ni pellet-type catalyst; Ru promotion; steam-methane reforming; daily startup and shutdown operation; fuel cell | SUPPORTED NI; SINTERING RESISTANCE; NICKEL; PERFORMANCE; PELLET; DRY | daily startup and shutdown operation; fuel cell; Ni pellet-type catalyst; Ru promotion; steam–methane reforming | English | 2023 | 2023-06 | 10.3390/catal13060949 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Revisit to Grain Boundary Effect in Pt Nanocrystals toward the Oxygen Electroreduction Reaction | The effect of catalytic surface defects in the oxygen reduction reaction (ORR) has been extensively studied to enhance the performance of proton-exchange-membrane fuel cells. Platinum (Pt)-based nanocatalysts have been used to overcome the poor performance of ORR, and Sabatier-type activity plots have been used to identify the optimal adsorption properties for ORR intermediates on the catalytic surface. Grain boundaries (GBs) within the nanostructures have been identified as the optimal active sites for ORR due to their reasonable coordination number and high oxygen residence time. However, oxidation of Pt atoms exposed at GB sites and leaching of non-noble metals from bimetallic Pt alloys have been identified as the "Achilles Heel" of GB-containing nanocatalysts. In this concept, we revisit the effect of GBs on nanocatalysts, summarize the mechanism of GBs towards ORR, and suggest outlooks for improving ORR for future design of nanocatalysts. | Kabiraz, Mrinal Kanti; Choi, Sang-Il | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Kabiraz, Mrinal/AAE-6381-2020; Choi, Sang-Il/N-7571-2013; Choi, Sangil/N-7571-2013 | 57201400780; 56167600800 | sichoi@knu.ac.kr; | CHEMCATCHEM | CHEMCATCHEM | 1867-3880 | 1867-3899 | 15 | 12 | SCIE | CHEMISTRY, PHYSICAL | 2023 | 3.8 | 41.3 | 0.94 | 2025-06-25 | 7 | 7 | electrocatalysis; grain boundary; oxygen reduction reaction; platinum; reaction mechanism | REDUCTION REACTION; PLATINUM; ELECTROCATALYSTS; CATALYSTS; SURFACES | electrocatalysis; grain boundary; oxygen reduction reaction; platinum; reaction mechanism | Electrocatalysis; Electrolytic reduction; Nanocatalysts; Oxygen; Platinum alloys; Proton exchange membrane fuel cells (PEMFC); Surface defects; Catalytic surfaces; Grain boundary effects; Grain-boundaries; Nano-catalyst; Oxygen electroreduction reactions; Oxygen reduction reaction; Performance; Platinum nanocrystals; Proton-exchange membranes fuel cells; Reaction mechanism; Grain boundaries | English | 2023 | 2023-06-22 | 10.1002/cctc.202300454 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Evaluation of SWER(Ze) Relationships by Precipitation Imaging Package (PIP) during ICE-POP 2018 | Improving estimation of snow water equivalent rate (SWER) from radar reflectivity (Ze), known as a SWER(Ze) relationship, is a priority for NASA's Global Precipitation Measurement (GPM) mission ground validation pro-gram as it is needed to comprehensively validate spaceborne precipitation retrievals. This study investigates the performance of eight operational and four research-based SWER(Ze) relationships utilizing Precipitation Imaging Probe (PIP) observations from the International Collaborative Experiment for Pyeongchang 2018 Olympic and Paralympic Winter Games (ICE-POP 2018) field campaign. During ICE-POP 2018, there were 10 snow events that are classified by synoptic conditions as either cold low or warm low, and a SWER(Ze) relationship is derived for each event. Additionally, a SWER(Ze) relationship is de-rived for each synoptic classification by merging all events within each class. Two new types of SWER(Ze) relationships are de-rived from PIP measurements of bulk density and habit classification. These two physically based SWER(Ze) relationships provided superior estimates of SWER when compared to the operational, event-specific, and synoptic SWER(Ze) relation-ships. For estimates of the event snow water equivalent total, the event-specific, synoptic, and best-performing operational SWER(Ze) relationships outperformed the physically based SWER(Ze) relationship, although the physically based relation-ships still performed well. This study recommends using the density or habit-based SWER(Ze) relationships for microphysical studies, whereas the other SWER(Ze) relationships are better suited toward hydrologic application. | Tokay, Ali; Helms, Charles N.; Kim, Kwonil; Gatlin, Patrick N.; Wolff, David B. | Univ Maryland, Goddard Earth Sci Technol & Res GESTAR II, Baltimore, MD 21201 USA; NASA Goddard Space Flight Ctr, Greenbelt, MD 20771 USA; Univ Maryland, Earth Syst Sci Interdisciplinary Ctr, College Pk, MD USA; Kyungpook Natl Univ, Ctr Atmospher Remote Sensing CARE, Daegu, South Korea; NASA Marshall Space Flight Ctr, Huntsville, AL USA; NASA Goddard Space Flight Ctr Wallops Flight Facil, Wallops Isl, VA USA | Kim, Kwonil/HTN-0103-2023; Wolff, David/H-5502-2012 | 6701653010; 51161295700; 57191964318; 8537480000; 7102190308 | tokay@umbc.edu; | JOURNAL OF HYDROMETEOROLOGY | J HYDROMETEOROL | 1525-755X | 1525-7541 | 24 | 4 | SCIE | METEOROLOGY & ATMOSPHERIC SCIENCES | 2023 | 3.1 | 41.4 | 0.33 | 2025-06-25 | 2 | 2 | Snowfall; Cloud microphysics; In situ atmospheric observations | SNOWFALL-RATE; MICROPHYSICAL PROPERTIES; RADAR REFLECTIVITY; FALL SPEED; DISDROMETER; RETRIEVAL; CLASSIFICATION; UNCERTAINTIES; IMPACT | Cloud microphysics; In situ atmospheric observations; Snowfall | cloud microphysics; image analysis; in situ measurement; radar imagery; snow water equivalent; synoptic meteorology | English | 2023 | 2023-04 | 10.1175/jhm-d-22-0101.1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Ink Tone Analysis of Printed Character Images towards Identification of Medieval Korean Printing Technique: The Song of Enlightenment (1239), the Jikji (1377), and the Gutenberg Bible (∼1455) | To identify printing techniques for medieval Korean books, ink tone analysis of printed characters is proposed. Ink tones of printed character images in two ancient books, The Song of Enlightenment with Commentaries by Buddhist Monk Nammyeong Cheon ( ), designated as Korean treasures in 1984 and 2012, were compared and analyzed. Both books have been misidentified and disclosed by the Cultural Heritage Administration of Korea as woodblock-printed versions from the Goryeo dynasty of Korea in the 13th century. Ink tone analysis showed clear differences in brightness histograms between printed characters on the two books, suggesting printing technique differences. Statistical ink tone analysis of printed characters in the two books revealed totally different brightness (or darkness) histograms of pixels, within inked areas, suggesting differences in printing techniques and materials used for the two books. Ink tone analysis was performed for the Jikji ( : metal type printed in Korea in 1337) and the Gutenberg Bible (metal type printed in Europe around 1455) for comparisons. As additional references, the ink tone analysis was conducted for two sets of old Korean books titled Myeongeuirok ( ), printed in 1777, and Sok-Myeongeuirok ( ), printed in 1778, using both metal type and re-carved woodblocks. The Gongin version of The Song of Enlightenment, designated as a Korean treasure in 2012, showed very similar distribution and average brightness of ink with the metal-type-printed books from Korea and Europe from the 14th to 18th centuries. All metal-type-printed books from Korea and the Gutenberg Bible showed spotty prints with lighter ink tones and more symmetrical histograms compared with woodblock printed Korean books from the 14th to 18th centuries. Ink tone analysis of printed character images can provide additional insights into a printing technique identification method. It is additional evidence for metal type printing of the Gongin version ( ) of The Song of Enlightenment, designated as a Korean treasure in 2012. The version of interest is the world's oldest extant book, printed using metal type in Korea in September 1239, as indicated in the imprint. This predates Jikji (1377) by 138 years and the 42-line Gutenberg Bible (similar to 1455) by 216 years. | Yoo, Woo Sik | WaferMasters Inc, Dublin, CA 94568 USA; Kyungpook Natl Univ, Inst Humanities Studies, Daegu 41566, South Korea | 55665974300 | woosik.yoo@wafermasters.com; | HERITAGE | HERITAGE-BASEL | 2571-9408 | 6 | 3 | ESCI | HUMANITIES, MULTIDISCIPLINARY;MULTIDISCIPLINARY SCIENCES | 2023 | 2 | 41.4 | 2.22 | 2025-06-25 | 3 | 5 | The Song of Enlightenment (); Jikji (); medieval Korean printing; Gutenberg Bible; image analysis; ink tone analysis; printing technique; metal type printing; woodblock printing | METAL-TYPE | Gutenberg Bible; image analysis; ink tone analysis; Jikji (直指); medieval Korean printing; metal type printing; printing technique; The Song of Enlightenment (); woodblock printing | English | 2023 | 2023-03 | 10.3390/heritage6030135 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A neurophysiological approach to the distinction between motor and cognitive skills: a functional magnetic resonance imaging study | This study investigated the neurophysiological differences underpinning motor and cognitive skills by measuring the brain activity via functional magnetic resonance imaging. Twenty-five healthy adults (11 women, 25.8 +/- 3.5 years of age) participated in the study. We developed three types of tasks, namely, simple motor task (SMT), complex motor task (CMT), and cognitive task (CT), using two-dimensional images of Gomoku, a traditional game known as five in a row. When shown the stimulus, participants were instructed to identify the best spot to win the game and to perform motor imagery of placing the stone for the SMT and CMT but not for the CT. Accordingly, we found significant activation from the CMT minus SMT contrast in the dorsolateral prefrontal cortex, posterior parietal cortex, precentral gyrus, and superior frontal cortex, which reflected increased visuospatial attention, working memory, and motor planning. From the CT minus SMT contrast, we observed significant activation in the left caudate nucleus, right medial prefrontal cortex, and right primary somatosensory cortex, responsible for visuospatial working memory, error detection, and cognitive imagery, respectively. The present findings indicate that adopting a conventional classification of cognitive and motor tasks focused on the extent of decision making and motor control involved in task performance might not be ideal. | Lu, Yunhang; Kim, Jingu; Kim, Teri | Kyungpook Natl Univ, Dept Phys Educ, Daegu, South Korea; Kyungpook Natl Univ, Inst Sports Sci, Daegu, South Korea | 57262012200; 18835844000; 57824218600 | terikim@knu.ac.kr; | FRONTIERS IN NEUROSCIENCE | FRONT NEUROSCI-SWITZ | 1662-453X | 17 | SCIE | NEUROSCIENCES | 2023 | 3.2 | 41.5 | 0.18 | 2025-06-25 | 1 | 1 | cognitive task; motor task; functional MRI; Gomoku; cognitive load | MEDIAL PREFRONTAL CORTEX; PREMOTOR CORTEX; WORKING-MEMORY; SUPPLEMENTARY; PERFORMANCE; INVOLVEMENT; ACTIVATION; STRATEGIES; AREAS; FINE | cognitive load; cognitive task; functional MRI; Gomoku; motor task | adult; article; brain function; caudate nucleus; child; clinical article; cognition; cognitive load; controlled study; decision making; dorsolateral prefrontal cortex; female; frontal cortex; functional magnetic resonance imaging; human; human experiment; imagery; medial prefrontal cortex; motor control; posterior parietal cortex; primary motor cortex; primary somatosensory cortex; school child; skill; spatial attention; task performance; working memory | English | 2023 | 2023-05-19 | 10.3389/fnins.2023.1178800 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Benzotriazole-containing fluorinated acrylic polymer coatings with high thermal stability, low surface energy, high visible-light transparency, and UV-blocking performance | Acryl chemistry provides the convenience of manufacturing various functional polymers because of a lot of commercially available monomers and a facile polymerization method. In this study, novel fluorinated acrylic polymers with a benzotriazole pendant were successfully synthesized via radical polymerization. These polymers exhibited considerably high thermal stabilities and low surface energies because of fluorinated alkyl groups along with excellent optical properties owing to the presence of fluorinated alkyl groups and the intense UV absorption of the benzotriazole moiety (i.e., relatively low refractive indices), illustrating perfect UV-blocking performances of up to approximately 380 nm. Moreover, polymer-coated PET films exhibited high visible-light transmittance due to the antireflection in the interface between the PET substrate and the polymer film. The present benzotriazole-containing fluorinated acrylic polymers are expected to be used as UV-blocking organic coating materials, especially for organic solar cell applications.

| ○ | ○ | Article | Determination of viscosities of alcohols, fatty oils, and mineral oils based on diffusion rates of fluids in a fluorescent microporous conjugated polymer film | A polydiphenylacetylene derivative containing a trimethylsilyl group in one of the two side phenyl rings (PDPA-C1) was examined for use in a film-type solid-state sensor to determine the viscosity of various fluids, such as alcohols, fatty oils, and mineral oils. The fluids readily diffused into the polymer film upon contact and, simultaneously, the fluorescence (FL) emission increased with time to reach a FL enhancing equilibrium. The FL enhancing rate decreased as the viscosity of the fluids increased. The relationship between the time to reach the FL enhancing equilibrium (t(eq), (FL)) and the viscosity of each fluid (eta) was captured well by a modified Forster-Hoffmann equation, log t(eq), (FL) = C + x log eta. The slope (x) values indicate the viscosity sensitivities of the PDPA-C1 film for the fluids, which were determined to be 1.02 for alcohols, 4.15 for fatty oils, and 0.63 for mineral oils. This sensing process yielded not only significantly higher viscosity sensitivities but also higher reproducibility than the conventional sensing process based on the measurement of FL intensity. The typical Forster-Hoffmann equation did not capture the relationship between the probe FL intensity and the fluid viscosity well. The unknown viscosities of commercial oils were identified exactly using the modified Forster-Hoffmann equation as a calibration curve. | Choi, Young-Ghil; Jin, Young-Jae; Lee, Wang-Eun; Lee, Jineun; Kwak, Giseop | Kyungpook Natl Univ, Sch Appl Chem Engn, Dept Polymer Sci & Engn, Polymer Nanomat Lab, 1370 Sankyuk Dong, Daegu 702701, South Korea; Korea Res Inst Chem Technol KRICT, Reliabil Assessment Ctr Chem Mat, 141 Gajeong Ro, Daejeon 305600, South Korea | , Giseop/M-8370-2018 | 57195627236; 55307815700; 26221842400; 57226333374; 17137322300 | gkwak@knu.ac.kr; | POLYMER BULLETIN | POLYM BULL | 0170-0839 | 1436-2449 | 80 | 2 | SCIE | POLYMER SCIENCE | 2023 | 3.1 | 41.6 | 0 | 2025-06-25 | 0 | 0 | Viscosity; Diffusion; Fluorescence; Microporous polymer; Conjugated polymer | EMISSION | Conjugated polymer; Diffusion; Fluorescence; Microporous polymer; Viscosity | Conjugated polymers; Diffusion in liquids; Microporosity; Mineral oils; Minerals; Polymer films; Semiconducting films; Viscosity; Diffusion rate; Fatty oil; Fluorescence intensities; Forster; Hoffmann equation; Microporous; Microporous polymers; Oil based; Sensing process; Trimethylsilyl groups; Fluorescence | English | 2023 | 2023-02 | 10.1007/s00289-022-04154-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Tracing characteristic variations of cellulose nanocrystals during the post-synthesis purification process | The production of cellulose nanocrystals (CNC) from biomass involves pretreatment, CNC synthesis, and post-synthesis purification. Information on quality variation during the different stages of pretreatment and CNC synthesis is well documented; however, the post-synthesis purification stage has received little attention. In this study, characteristic variations of CNC during the post-synthesis purification process were investigated. The stages in the process were washing (first and second), neutralization, and centrifugation. CNC's yield decreased after the second washing and neutralization. Cellobiose and cellotriose were detected in the supernatants after the first and second washings. After neutralization, CNC showed a higher colloidal dispersion compared to the first and the second washings. The dimension, morphological, and structural properties were moderately altered during the purification process. Crystallinity increased while crystallite size reduced as CNC purification progressed. The CtCBD3 bound to CNC's surface reduced by 24.27% after the second washing and increased by 47.44% after neutralization. The results in this study provide comprehensive information regarding the overall changes in CNC's characteristics during its purification. | Yeo, Hyeon Jin; Adedeji, Olajide Emmanuel; Kang, Mi Dan; Park, Hee-Soo; Shin, Minhye; Kim, Dong Hyun; Jung, Young Hoon | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Fed Univ Wukari, Dept Food Sci & Technol, PMB 1020, Wukari, Nigeria; Inha Univ, Sch Med, Dept Microbiol, Incheon 22212, South Korea; Gangneung Wonju Natl Univ, Dept Marine Food Sci & Technol, Kangnung 25457, Gangwon, South Korea | Adedeji, Olajide/GYU-3066-2022; Kim, Dong Hyun/LDT-2672-2024; Jung, Young Hoon/F-1703-2013; Park, Hee-Soo/AAC-6422-2019; Jung, Young/F-1703-2013 | 57208240157; 57202229091; 57311023600; 15751448400; 57208401604; 55574224522; 55550063700 | younghoonjung@knu.ac.kr; | POLYMER BULLETIN | POLYM BULL | 0170-0839 | 1436-2449 | 80 | 2 | SCIE | POLYMER SCIENCE | 2023 | 3.1 | 41.6 | 0.13 | 2025-06-25 | 1 | 1 | Cellulose nanocrystals; Crystallinity; Cellulose-binding protein; Surface morphology | BACTERIAL EXPANSIN BSEXLX1; EXTRACTION; BINDING; WASTE | Cellulose nanocrystals; Cellulose-binding protein; Crystallinity; Surface morphology | Anatomy; Biosynthesis; Cellulose Derivatives; Crystallinity; Purification; Sols; Biosynthesis; Cellulose derivatives; Crystallinity; Crystallite size; Morphology; Nanocellulose; Nanocrystals; Purification; Sols; Washing; Binding proteins; Cellulose-binding; Cellulose-binding protein; Cristallinity; Nanocrystal synthesis; Neutralisation; Postsynthesis; Pre-treatments; Purification process; Quality variation; Surface morphology | English | 2023 | 2023-02 | 10.1007/s00289-022-04121-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | The Right to Food and Responsibility to Protect in North Korea: In the Face of Food Availability Decline and Food Entitlement Decline | The North Korean authorities have the responsibility to protect (R2P) their people from starvation. Yet, reports of death from starvation in North Korea have been consistent since the widespread famine during the so-called "Arduous March." According to Amartya Sen, in a society with massive starvation and food refugees, famine crises are not merely due to food availability decline (FAD). Instead, the dominant variable in such crises is the food entitlement decline (FED) of vulnerable social groups. Therefore, since the repeated failure of the North Korean government to fulfill its responsibility justifies and obliges the international community to act, the "food entitlement" of the North Korean people needs to be further explored from social, economic, and political perspectives to help clarify and validate such international responsibility. Focusing on Kim Jong-un's leadership since 2012, this paper explores the substance and causes of FAD and FED in North Korea and monitors any changes. To seek effective commitments from the international community, including South Korea, the current research also analyzes the impact of the persistent violation of the people's right to food on the North Korean economic-social system and political regime, and the ensuing influence on the human rights situation with reference to the cases of Vietnam, China, and Mongolia in terms of the dichotomic social differentiation, beginnings of the civil society, and political change in the late-communist stage. | Heo, Man-ho | Kyungpook Natl Univ, Daegu, South Korea | 7005504107 | mhheo@knu.ac.kr; | PACIFIC FOCUS | PAC FOCUS | 1225-4657 | 1976-5118 | 38 | 3 | SSCI | AREA STUDIES;INTERNATIONAL RELATIONS | 2023 | 0.7 | 41.8 | 0 | 2025-06-25 | 0 | 0 | food availability decline (FAD); food entitlement decline (FED); responsibility to protect (R2P); class discrimination policy; market economy | class discrimination policy; food availability decline (FAD); food entitlement decline (FED); market economy; responsibility to protect (R2P) | English | 2023 | 2023-12 | 10.1111/pafo.12240 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
