| ○ | ○ | Article | Development of a mobile radon calibration system at KRISS | A mobile radon calibration system was developed with a high-sensitivity radon detector, a movable calibration chamber, and a Ra-226 solid source at the Korea Research Institute of Standards and Science (KRISS). The high-sensitivity radon detector was based on electrostatic collection mechanism. The volume of the calibration chamber was (1003.8 +/- 6.0) L. The mobile radon calibration system was calibrated with Rn-222 CRM from the radon primary system at KRISS. The sensitivities were established to be (231.8 +/- 16.1) cpm/(kBq/m(3)) for Po-218 and (254.9 +/- 17.8) cpm/(kBq/m(3)) for Po-214, respectively (k = 2). | Han, M. J.; Hwang, S. H.; Heo, D.

| ○ | ○ | Article | Consistency of Cubic Galileon Cosmology: Model-Independent Bounds from Background Expansion and Perturbative Analyses | We revisit the cosmological dynamics of the cubic Galileon model in light of the recently proposed model-independent analyses of the Pantheon supernova data. At the background level, it is shown to be compatible with data and preferred over standard quintessence models. Furthermore, the model is shown to be consistent with the trans-Planckian censorship conjecture (as well as other Swampland conjectures). It is shown that for the given parametrization, the model fails to satisfy the bounds on the reconstructed growth index derived from the Pantheon data set at the level of linear perturbations. | Brahma, Suddhasattwa; Hossain, Md Wali | McGill Univ, Dept Phys, Montreal, PQ H3A 2T8, Canada; Kyungpook Natl Univ, Ctr High Energy Phys, Daegu 37224, South Korea; Jamia Millia Islamia, Dept Phys, New Delhi 110025, India | 55454466800; 57207879193 | suddhasattwa.brahma@gmail.com;mhossain@jmi.ac.in; | UNIVERSE | UNIVERSE-BASEL | 2218-1997 | 7 | 6 | SCIE | ASTRONOMY & ASTROPHYSICS;PHYSICS, PARTICLES & FIELDS | 2021 | 2.813 | 45.7 | 0.13 | 2025-07-30 | 2 | 2 | swampland; dark energy; cubic Galileon cosmology | MODIFIED GRAVITY; HUBBLE CONSTANT; CONSTRAINTS; DYNAMICS; EQUATIONS; INFLATION; DISTANCE; ENERGY; SCALE | Cubic Galileon cosmology; Dark energy; Swampland | English | 2021 | 2021-06 | 10.3390/universe7060167 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Detection of Low-Energy X-rays Using YSO Scintillation Crystal Arrays for GRB Experiments | We developed an X-ray detector using 36 arrays, each consisting of a 64-pixellated yttrium oxyorthosilicate (YSO) scintillation crystal and a 64-channel multi-anode photomultiplier tube. The X-ray detector was designed to detect X-rays with energies lower than 10 keV, primarily with the aim of localizing gamma-ray bursts (GRBs). YSO crystals have no intrinsic background, which is advantageous for increasing low-energy sensitivity. The fabricated detector was integrated into UBAT, the payload of the Ultra-Fast Flash Observatory (UFFO)/Lomonosov for GRB observation. The UFFO was successfully operated in space in a low-Earth orbit. In this paper, we present the responses of the X-ray detector of the UBAT engineering model identical to the flight model, using Am-241 and Fe-55 radioactive sources and an Amptek X-ray tube. We found that the X-ray detector can measure energies lower than 5 keV. As such, we expect YSO crystals to be good candidates for the X-ray detector materials for future GRB missions. | Kim, Minbin; Ripa, Jakub; Park, Il H.; Bogomolov, Vitaly; Brandt, Soren; Budtz-Jorgensen, Carl; Castro-Tirado, Alberto J.; Chang, Sheng-Hsiung; Chang, Yenyun; Chen, Chia Ray; Chen, C-W; Chen, Pisin; Connell, Paul; Eyles, Chris; Gaikov, Georgii; Hong, Gihan; Huang, Jian Jung; Huang, Ming-Huey Alfred; Jeong, Soomin; Kim, Jieun; Lee, Jik; Lim, Heuijin; Lin, Chih-Yang; Liu, Tsung-Che; Nam, Jiwoo; Panasyuk, Mikhail; Petrov, Vasily; Reglero, Victor; Rodrigo, Juana M.; Svertilov, Sergey; Vedenkin, Nikolay; Wang, Ming Zu; Yashin, Ivan | Sungkyunkwan Univ, Dept Phys, 2066 Seobu Ro, Suwon 16419, South Korea; Sungkyunkwan Univ, Inst Sci & Technol Space, 2066 Seobu Ro, Suwon 16419, South Korea; Masaryk Univ, Fac Sci, Dept Theoret Phys & Astrophys, Brno 60177, Czech Republic; Moscow MV Lomonosov State Univ, Skobeltsyn Inst Nucl Phys Lomonosov, Moscow 119234, Russia; Lomonosov Moscow State Univ, Phys Dept, Moscow 119234, Russia; Tech Univ Denmark, Natl Space Inst, DK-2800 Lyngby, Denmark; Inst Astrofis Andalucia IAA CSIC, POB 03004, Granada 18080, Spain; Univ Malaga, Dept Ingn Sistemas & Automat, Unidad Asociada, CSIC, Malaga 29016, Spain; Natl Space Org, 9 Prosper 1st Rd,Hsinchu Sci Pk, Hsinchu 30078, Taiwan; Natl Taiwan Univ, Dept Phys, 1 Roosevelt Rd, Taipei 10617, Taiwan; Natl Taiwan Univ, Grad Inst Astrophys, 1 Roosevelt Rd, Taipei 10617, Taiwan; Natl Taiwan Univ, Leung Ctr Cosmol & Particle Astrophys, 1 Roosevelt Rd, Taipei 10617, Taiwan; Univ Valencia, GACE, Edif Ctr Invest, Valencia 46100, Spain; Natl United Univ, Dept Energy Engn, 2 Lienda Rd, Miaoli 36063, Taiwan; Agcy Def Dev, POB 35, Daejeon 34186, South Korea; Korea Polar Res Inst KOPRI, Div Atmospher Sci, 26 Songdomirae Ro, Incheon 21990, South Korea; Kyungpook Natl Univ, Ctr High Energy Phys, 80 Daehak Ro, Daegu 41566, South Korea; Dongnam Inst Radiol & Med Sci, Jwadong Gil 40, Busan 46033, South Korea; Natl Yang Ming Chiao Tung Univ, Dept Electrophys, 1001 Univ Rd, Hsinchu 300, Taiwan | ; chen, chen wen/GZM-3705-2022; Lavezzi, Lia/AAO-9660-2021; Jakub, Ripa/F-7526-2017; Chen, Pisin/IAO-8769-2023; Liu, Tiancai/C-6822-2011; Kim, Ji/AAU-5043-2020; Hong, GiHan/JQX-2798-2023; Chang, Sheng-Hsiung/V-5505-2019; Huang, Ming-Hsi/E-3872-2010; Castro-Tirado, Alberto/I-5039-2015; Ripa, Jakub/F-7526-2017 | 59075109500; 22935877100; 56419230500; 56419583200; 57214554770; 7004298620; 7006060970; 56984697300; 7501843644; 23466269700; 56075983000; 57222564782; 7005068948; 7004009631; 57196482080; 57206440605; 57207289899; 7404259744; 35104920200; 55916151000; 36835827400; 36619521200; 57317342100; 7405911064; 35225869700; 7004962170; 7402842714; 7004117262; 23976555900; 6603995484; 21733877200; 35228078700; 57213561618 | happykmb@gmail.com;jakub.ripa@ttk.elte.hu;ilpark@skku.edu;vit_bogom@nm.ru;sb@space.dtu.dk;carl@space.dtu.dk;ajct@iaa.es;judean@nspo.narl.org.tw;gixd@hep1.phys.ntu.edu.tw;chiaray@nspo.narl.org.tw;cwchen@nspo.narl.org.tw;pisinchen@phys.ntu.edu.tw;Paul.Connell@uv.es;cje@star.sr.bham.ac.uk;georgy.gaykov@gmail.com;hgh987321@naver.com;njinee@hotmail.com;mahuang@nuu.edu.tw;soominjeong@gmail.com;jekim@kopri.re.kr;jiklee999@gmail.com;heuijin.lim@gmail.com;sunnylin@nspo.narl.org.tw;diewanger@gmail.com;jwnam@phys.ntu.edu.tw;panasyuk@sinp.msu.ru;vas@srd.sinp.msu.ru;Victor.Reglero@uv.es;juana.m.rodrigo@hotmail.com;sis@coronas.ru;vnn.space@gmail.com;mwang@phys.ntu.edu.tw;ivn@eas.sinp.msu.ru; | UNIVERSE | UNIVERSE-BASEL | 2218-1997 | 7 | 11 | SCIE | ASTRONOMY & ASTROPHYSICS;PHYSICS, PARTICLES & FIELDS | 2021 | 2.813 | 45.7 | 0 | 2025-07-30 | 0 | 0 | gamma-ray burst; YSO; UBAT; UFFO | SLEWING MIRROR TELESCOPE; BURST; REDSHIFT; SPECTRA | Gamma-ray burst; UBAT; UFFO; YSO | English | 2021 | 2021-11 | 10.3390/universe7110396 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of chemical substitution on polytypes and extended defects in chalcopyrites: A density functional theory study | In ternary semiconductors, both stacking disorder and cation disorder can cause the formation of polytypes and extended defects. We perform density functional theory calculations to investigate the stability of polytypes in six ternary sulfides, such as CuIn S 2, CuGa S 2, CuAl S 2, AgIn S 2, AgGa S 2, and AgAl S 2. The formation energy of polytypes generated by stacking disorders is used to generate the anisotropic next-nearest neighbor Ising models. The estimated stacking fault energy by the model is in good agreement with the calculated stacking fault energy. The incorporation of Ga and Ag tends to suppress and promote the formation of stacking faults, respectively. On the other hand, the electronic bandgap of the polytypes generated by cation disorder is negatively correlated with the formation energy, resulting in the trapping of charge carriers at antisite domain boundaries. The formation of antisite domain boundaries can be suppressed by the incorporation of Ag and Ga. | Park, Kanghyeon; Jeong, Byeong-Hyeon; Lim, Hui Yeor; Park, Ji-Sang | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea | Park, Ji-Sang/F-9944-2010 | 57221558202; 57219744897; 57221552866; 36671796300 | jsparkphys@knu.ac.kr; | JOURNAL OF APPLIED PHYSICS | J APPL PHYS | 0021-8979 | 1089-7550 | 129 | 2 | SCIE | PHYSICS, APPLIED | 2021 | 2.877 | 45.7 | 0.33 | 2025-07-30 | 4 | 5 | STABILITY; CUINS2 | Aluminum alloys; Binary alloys; Carrier mobility; Copper alloys; Copper compounds; Density functional theory; Gallium alloys; Ising model; Positive ions; Silver; Stacking faults; Sulfur compounds; Density functional theory studies; Effect of chemicals; Electronic band gaps; Formation energies; Nearest neighbors; Stacking disorders; Stacking fault energies; Ternary semiconductors; Silver alloys | English | 2021 | 2021-01-14 | 10.1063/5.0038565 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Sustainable synthesis of carbon quantum dots from banana peel waste using hydrothermal process for in vivo bioimaging | Banana peel is a common solid biowaste. This paper reports a sustainable synthesis of carbon quantum dots (CQDs) from banana peel waste by a simple hydrothermal method. The resulting CQDs have a narrow size distribution, and the average particle size was measured as 5 nm. The nitrogen-containing and oxygen-containing functionalities on/in the surface of carbon structure were observed in the resulting CQDs. CQDs emit intense blue fluorescence under the excitation of UV-light (365 nm) with a good quantum yield of 20% without any surface passivation chemicals. Besides, CQDs exhibit excellent water solubility and excitation-dependent emission performance. Furthermore, the banana peel waste-derived CQDs had almost no photobleaching under UV-light irradiation for a long-time, suggesting that they have high photostability. Since no chemical reagent was involved in the synthesis of CQDs, the synthesized CQDs were confirmed to have lower toxicity for nematodes even at a high concentration of 200 mu g mL(-1). Because of the intense fluorescence with excellent fluorescence stability and biocompatibility, CQDs can be used for bioimaging in nematodes. The CQDs efficiently stained into the whole body of the nematodes and brightly illuminated the multicolor by varying the excitation wavelength. Therefore, fluorescent CQDs would be a great potential candidate for bioimaging applications. | Atchudan, Raji; Edison, Thomas Nesakumar Jebakumar Immanuel; Shanmugam, Mani; Perumal, Suguna; Somanathan, Thirunavukkarasu; Lee, Yong Rok | Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Vels Inst Sci Technol & Adv Studies VISTAS, Sch Basic Sci, Dept Chem, Chennai 600117, Tamil Nadu, India; Inst Aeronaut Engn, Dept Sci & Humanities, Hyderabad 500043, India | ; RAJI, ATCHUDAN/C-9904-2017; perumal, suguna/N-9075-2017; Edison, Thomas/N-8909-2015; Jebakumar Immanuel Edison, Thomas Nesakumar/N-8909-2015; Lee, Yong/K-6373-2015 | 26648054700; 6506181821; 58474957000; 56673798900; 14068969400; 57330662900 | atchudanr@yu.ac.kr;yrlee@yu.ac.kr; | PHYSICA E-LOW-DIMENSIONAL SYSTEMS & NANOSTRUCTURES | PHYSICA E | 1386-9477 | 1873-1759 | 126 | SCIE | NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, CONDENSED MATTER | 2021 | 3.369 | 45.7 | 19.47 | 2025-07-30 | 250 | 300 | Banana peel waste; Carbon quantum dots; Hydrothermal method; Nematodes; Bioimaging | Banana peel waste; Bioimaging; Carbon quantum dots; Hydrothermal method; Nematodes | Biocompatibility; Carbon; Carbon Quantum Dots; Fluorescence; Fruits; Nanocrystals; Particle size; Passivation; Photobleaching; Semiconductor quantum dots; Average particle size; Emission performance; Excitation wavelength; Hydrothermal methods; Hydrothermal process; Narrow size distributions; Surface passivation; UV-light irradiation; Hydrothermal synthesis | English | 2021 | 2021-02 | 10.1016/j.physe.2020.114417 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Light quality-dependent regulation of photoprotection and antioxidant properties in rice seedlings grown under different light-emitting diodes | We examined light quality-dependent regulation of photoprotection and antioxidant properties in rice seedlings. Seedlings grown under red or green light-emitting diodes (LEDs) showed declines in quantum yield of electron transport through PSII, maximum relative electron transport rates, and photochemical quenching compared to the white and blue LED, but no difference in maximum photochemical efficiency of PSII was found. Blue LED treatment resulted in greater increases in not only nonphotochemical quenching, but also zeaxanthin formation, expressions of beta-carotene hydroxylase and violaxanthin de-epoxidase, and anthocyanin compared to other LED treatments. By contrast, green and red LEDs increased activities of superoxide dismutase and ascorbate peroxidase as well as expression levels of catalase (CAT)a and CATb to white and blue LEDs. Green and red LEDs also greatly upregulated expressions of phytochrome (PHY) A, PHYB, PHYC, and cryptochrome 2 compared to white and blue LEDs, whereas blue LED upregulated CRY1. Our results demonstrate that specific wavelengths of different LEDs differentially influence photosynthetic performance, photoprotection, and antioxidant properties, possibly through regulating expressions of phytochrome and cryptochrome genes in a light-quality-dependent manner. | Tran, L.

| ○ | ○ | Article | Nitrogen fertilization levels influence the physicochemical properties of floury rice varieties | Background and objectives This study was conducted to determine the effect of nitrogen fertilization level during cultivation on physicochemical properties of two floury rice varieties (Shingil and Garumi 2) with different endosperm types under dry-milling process. Findings In both varieties, the protein content was increased in proportion to the level of nitrogen fertilization, while the amylose content exhibited a slight decrease in the highest nitrogen fertilization level. Damaged starch and digestible starch fractions were decreased with increasing nitrogen fertilization for both varieties, maybe due to the reduction in total starch relative to the protein content. Nevertheless, the level of damaged starch increased in Shingil under the highest nitrogen fertilization of 270 kg/ha, suggesting that nitrogen fertilization level can affect the physicochemical characteristics of starch particles during dry milling. The proportion of short amylopectin chains (DP6-12) decreased with increasing nitrogen fertilization. The difference was more prominent in Shingil than the other variety Garumi 2, indicating that Shingil could experience a greater increase in hardening and a faster retrogradation by increased nitrogen fertilization level than Garumi 2. Conclusions Nitrogen fertilization levels during rice growth affected the starch and protein contents in the endosperm, the chain length of amylopectin, which should, in turn, contribute to the processing properties of floury rice varieties. Significance and novelty This study will help develop fertilization strategies for the novel floury rice varieties and consequently provide helpful information to the rice-processing food industry. | Han, Chae-Min; Shin, Jong-Hee; Kwon, Jung-Bae; Won, Jong-Gun; Kim, Jong-Sang | Gyeongsangbuk Do Prov Agr Res & Extens Serv, Div Crops Res, Daegu, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | 57222965378; 55239526000; 57222961523; 57222964146; 37106950100 | jongsangkim@gmail.com; | CEREAL CHEMISTRY | CEREAL CHEM | 0009-0352 | 1943-3638 | 98 | 6 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY | 2021 | 2.534 | 45.9 | 0.72 | 2025-07-30 | 9 | 10 | endosperm type; nitrogen fertilization; rice flour; starch structure | STARCH; GELATINIZATION; DIGESTIBILITY; VISCOSITY | endosperm type; nitrogen fertilization; rice flour; starch structure | Amylopectins; Grain (agricultural product); Milling (machining); Nitrogen; Proteins; Damaged starch; Dry milling; Endosperm type; High-nitrogen; Nitrogen fertilization; Nitrogen fertilization level; Physicochemical property; Protein contents; Rice flour; Starch structure; Physicochemical properties | English | 2021 | 2021-11 | 10.1002/cche.10478 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Dieckol is a natural positive allosteric modulator of GABAA-benzodiazepine receptors and enhances inhibitory synaptic activity in cultured neurons | Phlorotannin supplement (PS) is a natural hypnotic substrate that modulates gamma-aminobutyric acid type A (GABA(A))-benzodiazepine (BZD) receptors. However, there is a lack of functional data assessing the role of individual components of PS, such as Dieckol, as allosteric activators of GABA(A) receptors (GABA(A)R). Using the whole cell patch clamp technique, we demonstrated that PS functionally enhanced the activity of GABA(A)-BZD receptors in a heterologous system and in primary cultured neurons. Application of diazepam (DZP) or Dieckol (1) increased GABA(A)R-mediated inward current in HEK293T cells containing the alpha 1 subunit in a dose-dependent manner, (2) which was blocked by co-treatment with the selective benzodiazepine site antagonist, flumazenil (FLZ); it also (3) increased the amplitude of GABA(A)-BZD receptors in primary cultured neurons, which was blocked by FLZ and (4) attenuated spontaneous activity in cultured neurons. These results indicate that PS and Dieckol act as positive allosteric activators of GABA(A)-BZD receptors, which might be the underlying mechanism of the sedative-hypnotic effect of PS. To our knowledge, this is the first study to directly link Dieckol-induced GABA(A)R activation via the BZD site binding and suppression of spontaneous neuronal activity in vitro. | Kwon, Sangoh; Jung, Jong Hoon; Cho, Suengmok; Moon, Kwang-Deog; Lee, Jaekwang | S&D Res & Dev Inst, Cheongju, South Korea; Korea Food Res Inst, Res Grp Funct Food Mat, Div Funct Food, Jeollabuk Do, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Major Food Biotechnol, Daegu, South Korea; Pukyong Natl Univ, Dept Food Sci & Technol, Busan, South Korea | ; Lee, Jongmin/Q-4909-2019; Cho, Suengmok/JCD-8778-2023 | 35484587500; 57194273651; 56486407400; 55999192900; 57206732862 | jklee@kfri.re.kr; | NUTRITIONAL NEUROSCIENCE | NUTR NEUROSCI | 1028-415X | 1476-8305 | 24 | 11 | SCIE | NEUROSCIENCES;NUTRITION & DIETETICS | 2021 | 4.062 | 46.0 | 0.63 | 2025-07-30 | 8 | 7 | Dieckol; phlorotannin; GABAA-benzodiazepine receptor; insomnia; cultured neurons; polyphenol; therapeutic agent; sleep | EYE-MOVEMENT SLEEP; BENZODIAZEPINE-RECEPTOR; GABA; PHLOROTANNINS; PHARMACOLOGY; ZOLPIDEM; SUBUNIT; BINDING; SITE; MICE | cultured neurons; Dieckol; GABAA-benzodiazepine receptor; insomnia; phlorotannin; polyphenol; sleep; therapeutic agent | Benzofurans; gamma-Aminobutyric Acid; HEK293 Cells; Humans; Neurons; Receptors, GABA-A; 4 (2 hydroxyethyl) 1 piperazineethanesulfonic acid; 4 aminobutyric acid; benzodiazepine; benzodiazepine receptor; diazepam; flumazenil; sedative agent; 4 aminobutyric acid; 4 aminobutyric acid A receptor; benzofuran derivative; dieckol; allosterism; Article; binding assay; cognition; cytotoxicity; electrophysiology; emotion; excitatory postsynaptic potential; insomnia; nerve cell culture; nonhuman; protein expression; room temperature; site directed mutagenesis; HEK293 cell line; human; metabolism; nerve cell | English | 2021 | 2021-11-02 | 10.1080/1028415x.2019.1681089 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | CONFORMAL VECTOR FIELDS ON ALMOST CO-KAHLER MANIFOLDS | In this paper, we characterize almost co-Kahler manifolds with a conformal vector field. It is proven that if an almost co-Kahler manifold has a conformal vector field that is collinear with the Reeb vector field, then the manifold is a K-almost co-Kahler manifold. It is also shown that if a (kappa, mu)-almost co-Kahler manifold admits a Killing vector field V, then either the manifold is K-almost co-Kahler or the vector field V is an infinitesimal strict contact transformation, provided that the (1,1) tensor h remains invariant under the Killing vector field.

| ○ | ○ | Article | Fabrication of highly thermal conductive PA6/hBN composites via in-situ polymerization process | In this research, thermally conductive polyamide 6/hexagonal boron nitride (PA6/hBN) nanocomposites waaere fabricated via an in-situ ring-opening polymerization of epsilon -caprolactam. The hBN filler was exfoliated through a co-solvent exfoliation process and then chemically modified to form an epsilon -caprolactam-grafted BN (cBN). After that, PA6 was introduced onto the cBN surface using a grafting from method. The thermal conductivities of the PA6/cBN composites significantly increased up to 180 % when the BN content was 16.5 wt%. The tensile strength and Young's modulus of the PA6/cBN composites with 16.5 wt% hBN increased by 30 % and 92 %, respectively, compared to the pristine PA6. The grafted PA6 on BN composites exhibited strong polymer-filler interfacial interactions. Overall, this study provides a facile method of fabricating high-performance PA6 with improved thermal and mechanical properties and higher thermal conductivity. | Zhang, He-xin; Seo, Do Hyun; Lee, Dong-Eun; Yoon, Keun-Byoung | Anhui Univ Technol, Sch Chem & Chem Engn, Maanshan, Peoples R China; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Architecture & Civil Engn, Daegu, South Korea | Hexin, Zhang/ACI-3911-2022 | 25633288200; 57221464293; 56605563300; 7401607550 | polyhx@ciac.ac.cn;dolee@knu.ac.kr;kbyoon@knu.ac.kr; | JOURNAL OF POLYMER RESEARCH | J POLYM RES | 1022-9760 | 1572-8935 | 28 | 2 | SCIE | POLYMER SCIENCE | 2021 | 3.061 | 46.1 | 0.16 | 2025-07-30 | 6 | 5 | Polyamide-6; Hexagonal boron nitride; Nanocomposite; Thermal conductivity | Hexagonal boron nitride; Nanocomposite; Polyamide-6; Thermal conductivity | Cubic boron nitride; Fabrication; Filled polymers; Fillers; Grafting (chemical); III-V semiconductors; Tensile strength; Thermal conductivity; c-BN surface; Chemically modified; Facile method; Grafting from method; In-situ polymerization process; Interfacial interaction; Polymer-filler; Thermal and mechanical properties; Ring opening polymerization | English | 2021 | 2021-01-11 | 10.1007/s10965-020-02378-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Synthetization of hybrid nanocellulose aerogels for the removal of heavy metal ions | This study aims to explore heavy metal ion adsorbents with excellent removal performance. For this, chitosan and gelatin-based hydrogel beads (Hyb) were prepared and crosslinked with a nanocellulose structure using ammonium zirconium carbonate (AZC) and calcium chloride (Ca). The prepared hybrid aerogels, HybAZC and HybCa, were characterized by using various techniques to investigate their respective morphologies and functional groups for a better understanding of their capacity for heavy metal ion adsorption. Then, we systematically investigated the difference in removal and adsorption capacities of heavy metal ions for single and multiple ion cases using the prepared aerogels-HybAZC and HybCa. The tested heavy metal ions were Hg(II), Pb(II), Cd(II), and Cr(III) ions. For the adsorption systems with single ion (S-HybAZC and S-HybCa) cases, every single metal ionic solution was studied in the presence of the aerogels; but for the multiple ion (M-HybAZC and M-HybCa) adsorption systems, mixed metal ionic solutions with predetermined concentrations of four heavy metal ions were studied. In a single system using S-HybAZC and S-HybCa aerogels, the removal efficiencies of all metal ions except the Cd(II) ion (using S-HybCa) were calculated to be above 65%. In multiple systems, regardless of the quality or quantity of aerogels or metal ions, the removal efficiencies were calculated to be above 85%. Overall, results suggest the prepared aerogels HybAZC and HybCa can be employed as effective adsorbents for single and multiple systems. Thus, hybrid nanocellulose aerogels have great potential for practical applications in the removal of heavy metal ions. | Perumal, Suguna; Lee, Hansol; Jeon, Sangmin; Yoon, Dong Ho; Cheong, In Woo | Kyungpook Natl Univ, Sch Engn, Dept Appl Chem, Daehak Ro 80, Daegu 41566, South Korea; Yeungnam Univ, Sch Chem Engn, Gyongsan 38541, South Korea; Pohang Univ Sci & Technol POSTECH, Dept Chem Engn, 77 Cheongam Ro, Pohang, Gyeongbuk, South Korea; Kuk Il Paper Mfg Co Ltd, R&D Ctr, Baekok Daero 563, Yongin 17128, South Korea | perumal, suguna/N-9075-2017 | 56673798900; 55701189200; 7203005726; 57205212303; 7006733373 | suguna.perumal@gmail.com;inwoo@knu.ac.kr; | JOURNAL OF POLYMER RESEARCH | J POLYM RES | 1022-9760 | 1572-8935 | 28 | 8 | SCIE | POLYMER SCIENCE | 2021 | 3.061 | 46.1 | 0.47 | 2025-07-30 | 6 | 6 | Hydrogel beads; Nanocellulose fibers; Crosslinker; Removal efficiencies; Adsorption capacities; Heavy metal ions | AMMONIUM ZIRCONIUM CARBONATE; GRANULAR ACTIVATED CARBON; CROSS-LINKING; HYDROGEL PARTICLES; AQUEOUS-SOLUTIONS; CELLULOSE FIBERS; WASTE; ADSORPTION; CHITOSAN; CADMIUM | Adsorption capacities; Crosslinker; Heavy metal ions; Hydrogel beads; Nanocellulose fibers; Removal efficiencies | Adsorption; Cadmium Compounds; Calcium Chloride; Cellulose; Chromium Compounds; Efficiency; Adsorption; Cadmium compounds; Calcium chloride; Cellulose; Cellulose nanocrystals; Chromium compounds; Efficiency; Heavy metals; Lead compounds; Mercury compounds; Metal ions; Nanocellulose; Zirconium compounds; Adsorption capacities; Adsorption system; Heavy metal ion adsorptions; Hybrid aerogels; Multiple systems; Removal efficiencies; Removal of heavy metal ions; Removal performance; Aerogels | English | 2021 | 2021-08 | 10.1007/s10965-021-02693-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | The Neural Correlates of Positive Versus Negative Thought-action Fusion in Healthy Young Adults | Objective: Thought-action fusion (TAF), one of the most-studied dysfunctional beliefs in obsessive-compulsive disorder, represents an individual's belief that his/her thoughts directly influence events. TAF belief types are divided into personal thoughts relating to positive (positive TAF) and negative outcomes (negative TAF). However, the neural mechanisms underlying both aspects of the TAF response remain elusive. Methods: This functional magnetic resonance imaging study aimed to investigate the neural circuits related to positive and negative TAF and their relationships with psychological measures. Thirty-one healthy male volunteers participated in a modified TAF task wherein they were asked to read the name of a close person embedded in positive statements (PS) or negative statements (NS). Results: Conjunction analysis revealed activation of the fusiform and lingual gyri, midcingulate and superior medial frontal gyri, inferior orbitofrontal gyrus, and temporoparietal junction. The NS > PS comparison showed additional activation in the precuneus and medial prefrontal cortex, superior frontal gyrus, insula, globus pallidus, thalamus, and midbrain. Precuneus activity was associated with the TAF score among these areas. Moreover, activity in the inferior orbitofrontal gyrus, insula, superior, middle and medial frontal gyri, globus pallidus, inferior parietal lobule, and precuneus was associated with dimensional obsessive-compulsive scores. In contrast, the PS > NS comparison revealed no significant activation. Conclusion: These results suggest that negative TAF, relative to positive TAF, recruits additional regions for self-referential processing, salience, and habitual responding, which may contribute to the activation of the belief that a negative thought increases the probability of that negative outcome. | Lee, Sang Won; Cha, Hyunsil; Jang, Tae Yang; Kim, Eunji; Song, Huijin; Chang, Yongmin; Lee, Seung Jae | Kyungpook Natl Univ, Dept Psychiat, Chilgok Hosp, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Psychiat, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Med & Biol Engn, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Psychiat, Daegu, South Korea; Seoul Natl Univ Hosp, Biomed Res Inst, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Radiol, Daegu, South Korea | Lee, Seung/AAI-1191-2020 | 55820414800; 57189728122; 57219848497; 57215273419; 8231186700; 7501840633; 58509400200 | ychang@knu.ac.kr;jayleemd@knu.ac.kr; | CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE | CLIN PSYCHOPHARM NEU | 1738-1088 | 2093-4327 | 19 | 4 | SCIE | NEUROSCIENCES;PHARMACOLOGY & PHARMACY | 2021 | 3.731 | 46.1 | 0.2 | 2025-07-30 | 2 | 3 | Thought-action fusion; Cognitive theory; Obsessive-compulsive disorder; Cortico-striato-thalamo-cortical circuit; Affective network; Salience network | OBSESSIVE-COMPULSIVE DISORDER; COGNITIVE FUSION; PERSPECTIVE; PREDICTORS; INVENTORY | Affective network; Cognitive theory; Cortico-striato-thalamo-cortical circuit; Obsessive-compulsive disorder; Salience network; Thought-action fusion | adult; anxiety assessment; Article; behavior assessment; brain function; brain region; cingulate gyrus; comparative study; controlled study; correlation analysis; functional magnetic resonance imaging; fusiform gyrus; globus pallidus; human; human experiment; inferior parietal lobule; insula; lingual gyrus; male; medial prefrontal cortex; mesencephalon; middle frontal gyrus; negative thought action fusion; nerve cell network; normal human; orbital cortex; positive thought action fusion; precuneus; psychologic assessment; psychological aspect; scoring system; superior frontal gyrus; temporoparietal junction; thalamus; thinking; young adult | English | 2021 | 2021-11 | 10.9758/cpn.2021.19.4.628 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Degradation Properties of Refractory MoNbTaVW High-Entropy Alloys with Simultaneous Si/Al Pack Cementation Coatings Under High-Temperature Flame Tests | This paper aims to improve the oxidation resistance of MoNbTaVW (at%) refractory high-entropy alloys after flame tests at 1350 celcius with Si/Al pack cementation coatings. After the Si/Al pack cementation coatings were applied, a coating layer of about 80 mu m with a sequence of Si-rich layer (silicide)/interdiffusion layer/Al-rich layer (aluminide)/Al diffusion layer was formed. After the flame tests at 1350 degrees C for 20 min, the uncoated specimens formed composite oxides of Nb2O5 (s), Ta2O5 (s), and V2O5 (s) with porosity of MoO3 (g) and WO3 (g) with a weight gain. On the other hand, the Si/Al coated specimens were composed of Si-rich layer (silicide)/interdiffusion layer/Al-rich layer (aluminide)/Al diffusion layer. After the flame tests, SiO2 and Al2O3 ceramic protective layers were formed on the surface and prevented additional oxidation. The oxidation behaviors of MoNbTaVW alloys and the Si/Al pack cementation coated alloys were discussed with microstructures and phase development.

| ○ | ○ | Article | Effect of finish line locations of tooth preparation on the accuracy of intraoral scanners | Aim: The purpose of this study was to compare the accuracy of intraoral scanning on a tooth model according to four finish line conditions (supragingival, equigingival, subgingival, and subgingival with gingival cord). Materials and methods: To simulate the clinical situation, the abutment was fabricated using ceramic materials. A pigment was added to the transparent orthodontic silicone to create a translucent gingiva. A CAD reference model (CRM) was obtained using a contact scanner. Finish lines on the tooth preparation were placed at the subgingival (0.5 mm below the level of the gingiva), equigingival, and supragingival (0.5 mm above the level of the gingiva) locations. In addition, a gingival cord was packed into the gingival sulcus below the subgingival finish line. A CAD test model (CTM) was obtained using two types of intraoral scanners (IOSs), i500 (Medit) and EZIS PO (DDS; N = 20 per locations). CRM and CTM were superimposed and analyzed using 3D analysis software. In the statistical analysis, the comparison of accuracy according to the finish line locations was confirmed by one-way ANOVA (alpha = 0.05). The differences between the groups were analyzed using the Tukey HSD post-hoc test. Result: There was a significant difference in the accuracy of intraoral scanning according to the finish line locations of the tooth preparations (P < 0.001). The equigingival and subgingival finish lines showed poor accuracy. The use of gingival cords significantly improved the accuracy (P < 0.05). There were significant differences between the two types of IOSs, with the i500 showing better accuracy than the EZIS PO (P< 0.001). Conclusion: Supragingival finish lines or the use of gingival displacement cords is recommended for clinically acceptable accuracy (< 100 mu m) of the marginal region captured with an IOS. | Son, Keunbada; Lee, Kyu-Bok | Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu, South Korea; Kyungpook Natl Univ, Adv Dent Device Dev Inst A3DI, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu, South Korea | Son, Keunbada/AAG-8089-2019; SON, Keunbada/AAG-8089-2019 | 57202916520; 15925571200 | kblee@knu.ac.kr; | INTERNATIONAL JOURNAL OF COMPUTERIZED DENTISTRY | INT J COMPUT DENT | 1463-4201 | 24 | 1 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2021 | 2.923 | 46.2 | 3.21 | 2025-07-30 | 31 | 36 | finish line; tooth preparation; intraoral scanner; accuracy | GINGIVAL DISPLACEMENT; MARGIN PLACEMENT; SYSTEMS; FIT | accuracy; finish line; intraoral scanner; tooth preparation | Computer-Aided Design; Dental Impression Technique; Dental Models; Humans; Tooth; Tooth Preparation; computer aided design; dental impression; dental procedure; dental surgery; diagnostic imaging; human; tooth | English | 2021 | 2021-봄 | 바로가기 | 바로가기 | 바로가기 |
