| ○ | ○ | Article | Heterojunction interface passivation strategy for Cu(In1-x,Gax)Se2 solar cell with nano-level engineering of Zn-based buffer structure via atomic layer deposition method | The global needs for ecological friendliness and sustainable development in the photovoltaic (PV) market have led to an increased demand to fabricate solar cells in an environmentally sound manner using nontoxic elements. In response to these requirements, in chalcogenide solar cell technology, researchers are attempting to replace the conventional CdS buffer. A potential replacement buffer material is ZnOS due to its direct, large, and tunable bandgap. Atomic layer deposition (ALD) can be effectively used to deposit ZnOS on Cu(In1-x,Ga-x)Se-2 (CIGSe) absorbers, as this process allows the highly controlled thickness and composition, conformal coverage, inline compatibility, and relatively easier maintenance. However, CIGSe solar cells with an ALD grown ZnOS buffer usually suffer from the deficit of open circuit voltage (V-oc), which limits power conversion efficiency (PCE). To overcome the limitation, ZnOS buffer structure with ZnS nanolayer is engineered for heterojunction interface passivation (HIP) and the role of ZnS nanolayer is investigated. The insertion of the ZnS nanolayer between ZnOS and CIGSe exhibits passivation effects at the heterojunction interface, thereby to enhance the solar cell performance owing to the realization of a more refined bandgap structure. Wide bandgap ZnS passivation thus demonstrates considerable potentials for being applied in other material systems. | Shin, Sang Su; Kim, Kihwan; Yoo, Jinsu; Kim, Ji Hye; Ahn, Seungkyu; Cho, Ara; Kim, Dongryeol; Jo, Yonghee; Jeong, Inyoung; Shin, Donghyeop; Cho, Jun-Sik; Yun, Jae Ho; Park, Jonghoo; Park, Joo Hyung | Korea Inst Energy Res KIER, Photovolta Res Dept, Daejeon 34129, South Korea; Kyungpook Natl Univ, Dept Elect Engn, Daegu 41566, South Korea; Ind Surface Adv Coating ISAC Res Inc, Daejeon 34036, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea; Jeonbuk Natl Univ, Dept Elect Engn, Jeonju 54896, South Korea; Jeonbuk Natl Univ, Smart Grid Res Ctr, Jeonju 54896, South Korea | ; Park, Joo Hyung/AAL-5247-2020; Shin, Donghyeop/A-2007-2015; Yun, JaeHo/NGS-4691-2025 | 57217686358; 55710512500; 25652270600; 57202728914; 45760971600; 36349160700; 57194069208; 57646774900; 55211092800; 35103548400; 7403535861; 56431966500; 57196408322; 57193059568 | joopark@kier.re.kr; | SOLAR ENERGY MATERIALS AND SOLAR CELLS | SOL ENERG MAT SOL C | 0927-0248 | 1879-3398 | 224 | SCIE | ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2021 | 7.305 | 17.7 | 0.62 | 2025-07-30 | 11 | 12 | Heterojunction interface passivation; ZnS nanolayer; ZnOS buffer; Bandgap engineering; Cu(In,Ga)Se-2 thin film solar cell | CHEMICAL-VAPOR-DEPOSITION; JUNCTION FORMATION; BATH DEPOSITION; INDIUM SULFIDE; FILMS; EFFICIENCY; COEVAPORATION; PERFORMANCE; IMPACT; GROWTH | Bandgap engineering; Cu(In,Ga)Se<sub>2</sub> thin film solar cell; Heterojunction interface passivation; ZnOS buffer; ZnS nanolayer | Cadmium sulfide; Cadmium sulfide solar cells; Cell engineering; Conversion efficiency; Copper alloys; Energy gap; Gallium alloys; Heterojunctions; II-VI semiconductors; Indium alloys; Nanostructured materials; Open circuit voltage; Passivation; Semiconductor alloys; Wide band gap semiconductors; Zinc sulfide; Band-gap structures; Chalcogenide solar cells; Conformal coverage; Controlled thickness; Heterojunction interfaces; Passivation effect; Power conversion efficiencies; Solar cell performance; Atomic layer deposition | English | 2021 | 2021-06-01 | 10.1016/j.solmat.2021.111010 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of distance between the abutment and the adjacent teeth on intraoral scanning: An in vitro study | Statement of problem. The introduction of intraoral scanners has increased the use of digital technology in dental procedures. However, data on the accuracy of abutment scans according to the distance between the adjacent tooth and the abutment are lacking. Purpose. The purpose of this in vitro study was to compare the 3D accuracy of abutment scans according to the distance between the adjacent tooth and the abutment. Material and methods. A right maxillary first molar was removed and scanned with an industrial 3D scanner, and the image was extracted as a standard tessellation language (STL) file. Six virtual models with 1-mm, 1.5-mm, 2-mm, 2.5-mm, 3-mm, and 3.5-mm spacing between abutment teeth and adjacent teeth were fabricated with an industrial computer-aided design (CAD) software program. Then, 6 master models were fabricated with a 3D printer and copied into dental gypsum. The replicated models (reference models) were scanned 20 times with an intraoral scanner (C53600); the resulting model was referred to as the CAD test model. The adjacent teeth of the reference models were deleted, and the models were scanned with a laboratory scanner; the resulting model was referred to as the CAD reference model. The CAD reference model was used to measure the scan accuracy in 4 directions (buccal, lingual, mesial, and distal) and 4 areas (occlusal, angle, axial, and margin) by using a 3D inspection software program. The Friedman nonparametric test (alpha=.05) was used for comparison, and post hoc testing was performed by using the Mann-Whitney U-test and Bonferroni correction method (direction and area variables; of alpha=.0008, distance variable; of alpha=.0003). Results. The buccal, lingual, mesial, and distal directions of the abutment were significantly different according to distance (P<.001). The margin, axial, angle, and occlusal regions of the abutment were also significantly different according to distance (P<.001). Conclusions. The distance between the abutment teeth and adjacent teeth affected the accuracy of the abutment scan. In intraoral scanning, when the distance between the abutment teeth and the adjacent teeth is more than 1.5 mm, the scan error does not increase, and more accurate scan data can be obtained. | Huang, Mei-Yang; Son, KeunBaDa; Lee, Kyu-Bok | Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu, South Korea | SON, Keunbada/AAG-8089-2019; Huang, Mei-Yang/AAZ-1987-2020; Son, Keunbada/AAG-8089-2019 | 57216625596; 57202916520; 15925571200 | kblee@knu.ac.kr; | JOURNAL OF PROSTHETIC DENTISTRY | J PROSTHET DENT | 0022-3913 | 1097-6841 | 125 | 6 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2021 | 4.148 | 17.9 | 3.27 | 2025-07-30 | 23 | 28 | IMPRESSION TECHNIQUES; CLINICAL-EVALUATION; DIGITAL IMPRESSION; TREATMENT COMFORT; VIVO PRECISION; ACCURACY; SCANNERS; PERCEPTION; EFFICIENCY; CROWNS | Computer-Aided Design; Imaging, Three-Dimensional; computer aided design; three-dimensional imaging | English | 2021 | 2021-06 | 10.1016/j.prosdent.2020.02.034 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Evaluation of intaglio surface trueness and margin quality of interim crowns in accordance with the build angle of stereolithography apparatus 3-dimensional printing | Statement of problem. Studies on the intaglio surface trueness and margin quality of interim crowns fabricated using stereolithography apparatus (SLA) 3D printing depending on the type of tooth and the build angle are lacking. Purpose. The purpose of this in vitro study was to evaluate the effects of intaglio surface trueness and margin quality in accordance with the type of tooth and the build angles of interim crowns fabricated by SLA 3D printing. Materials and methods. A definitive cast was digitized for computer-aided design (CAD) reference model (CRM) production, and the interim crown was designed by using a CAD software program and saved as a standard tessellation language (STL) file. For CAD test model (CTM) production, 3D printing was performed in accordance with the type of tooth (maxillary central incisor, first premolar, and first molar) and the build angles (90, 120, 135, 150, 180, 210, 225, 240, and 270 degrees) (n=17). The intaglio surface of the printed interim crown was digitized. CRM and CTM used 3D inspection software to analyze the intaglio surface superimposition and root mean square (RMS). In addition, a grading system was developed to evaluate the margin quality, which was assessed visually. Statistical analysis was performed using 1-way ANOVA, 2-way ANOVA, and the Tukey honestly significant difference post hoc test (alpha=.05). Results. The RMS value showed significant differences in the various types of tooth as per the build angles (P<.001). The central incisor and first premolar showed the lowest RMS value at 180 degrees, and the first molar showed the lowest RMS value at 210 degrees. The margin quality was significantly different as per the build angle in the central incisor and the first molar (P<.05). The worst margin quality observed in all teeth was at 180 degrees. Conclusions. In 3D printing, the build angle affected the intaglio surface trueness of the interim crown. The recommended build angle for interim crowns fabricated using 3D printing is between 150 and 210 degrees. The tooth type affected the margin quality according to the build angle, except in the case of first premolars. | Yu, Beom-Young; Son, KeunBaDa; Lee, Kyu-Bok | Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu, South Korea | Son, Keunbada/AAG-8089-2019; SON, Keunbada/AAG-8089-2019 | 57209287190; 57202916520; 15925571200 | kblee@knu.ac.kr; | JOURNAL OF PROSTHETIC DENTISTRY | J PROSTHET DENT | 0022-3913 | 1097-6841 | 126 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2021 | 4.148 | 17.9 | 7.64 | 2025-07-30 | 60 | 59 | DENTAL MODELS; ACCURACY; PRECISION | Computer-Aided Design; Crowns; Printing, Three-Dimensional; Stereolithography; analysis of variance; article; first molar; first premolar; human; in vitro study; language; maxillary central incisor; post hoc analysis; software; stereolithography; computer aided design; three dimensional printing; tooth crown | English | 2021 | 2021-08 | 10.1016/j.prosdent.2020.04.028 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Fabricating a custom tray for an impression of multiple abutment teeth by using an open-source software program | Although intraoral scanners have gained in popularity, the traditional impression technique with a custom tray is still useful, particularly when making a definitive impression of multiple abutment teeth. A custom tray can be fabricated with a dental software program, avoiding the disadvantages of the manual laboratory procedures. However, additional module purchasing is necessary. This article presents a digital workflow for designing a custom tray by using an opensource software program.

| ○ | ○ | Article | Antifreeze Protein Improves the Cryopreservation Efficiency of Hosta capitata by Regulating the Genes Involved in the Low-Temperature Tolerance Mechanism | In this study, whether the addition of antifreeze protein (AFP) to a cryopreservative solution (plant vitrification solution 2 (PVS2)) is more effective in reducing freezing injuries in Hosta capitata than PVS2 alone at different cold exposure times (6, 24, and 48 h) is investigated. The upregulation of C-repeat binding factor 1 (CBF1) and dehydrin 1 (DHN1) in response to low temperature was observed in shoots. Shoots treated with distilled water (dH(2)O) strongly triggered gene expression 6 h after cold exposure, which was higher than those expressed in PVS2 and PVS2+AFP. However, 24 h after cold exposure, gene expressions detected in dH(2)O and PVS2 treatments were similar and higher than PVS2 + AFP. The expression was highest in PVS2+AFP when the exposure time was extended to 48 h. Similarly, nitric reductase activities 1 and 2 (Nia1 and Nia2) genes, which are responsible for nitric oxide production, were also upregulated in low-temperature-treated shoots, as observed for CBF1 and DHN1 expression patterns during cold exposure periods. Based on the gene expression patterns, shoots treated with PVS2+AFP were more likely to resist cold stress, which was also associated with the higher cryopreservation efficiency of PVS2+AFP compared to PVS2 alone. This finding suggests that the improvement of cryopreservation efficiency by AFP could be due to the transcriptional regulation of CBF1, DHN1, Nia1, and Nia2, which might reduce freezing injuries during cryopreservation. Thus, AFP could be potentially used as a cryoprotectant in the cryopreservation of rare and commercially important plant germplasm. | Pe, Phyo Phyo Win; Naing, Aung Htay; Kim, Chang Kil; Park, Kyeung Il | Yeungnam Univ, Dept Hort & Life Sci, Gyongsan 38541, South Korea; Yezin Agr Univ, Dept Hort, Nay Pyi Taw 15013, Myanmar; Kyungpook Natl Univ, Dept Hort, Daegu 41566, South Korea | Naing, Aung Htay/AAF-4277-2019 | 57210446910; 37112768100; 7409880701; 7408066185 | phyophyo.yau@gmail.com;aunghtaynaing2005@gmail.com;ckkim@knu.ac.kr;pki0217@yu.ac.kr; | HORTICULTURAE | HORTICULTURAE | 2311-7524 | 7 | 4 | SCIE | HORTICULTURE | 2021 | 2.923 | 18.1 | 0.43 | 2025-07-30 | 5 | 5 | antifreeze protein; cryopreservation; endangered plant germplasm; gene expression; low-temperature tolerance | Antifreeze protein; Cryopreservation; Endangered plant germplasm; Gene expression; Low-temperature tolerance | English | 2021 | 2021-04 | 10.3390/horticulturae7040082 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Characteristics and Trends of Strawberry Cultivars throughout the Cultivation Season in a Greenhouse | Each strawberry (Fragaria x ananassa) cultivar has its own growth and yield characteristics. However, the characteristics of many cultivars have not been determined at a consistent time and place, making direct comparative analysis difficult. The objective of this study was to identify characteristics and trends of five Korean strawberry cultivars in the same environment during an entire season. Therefore, environmental factors such as daily average air temperature, daily average relative humidity, daily average solar radiation, daily soil temperature, daily soil water content, daily soil electrical conductivity (EC), plant growth characteristics such as the number of leaves, plant height, leaf length, leaf width, and crown diameter, and productivity characteristics such as flowering and fruiting were measured to investigate the possible correlations of the data over one season. The vegetative growth of "Seolhyang" and "Keumsil" was greater than that of "Jukhyang" and "Maehyang". The yield of "Arihyang" was greater than that of all other cultivars. "Arihyang" also presented the greatest weight per number of fruits. Among environmental factors, higher variability in air temperature and soil water content was correlated to lower total fresh weight in the following week at different degrees for each cultivar. Among the cultivars, the time to the first flowering was delayed by about seven days when the number of leaves increased by one and was reduced by one day per 1 cm increase in plant height. The total fresh weight was enhanced up to 271 g per experimental unit, while the average number of leaves increased by one. The results indicate that the data can be used by those who need information regarding the characteristics of the strawberry cultivars through direct comparative analysis. | Ahn, Min Gyu; Kim, Dong Sub; Ahn, Su Ran; Sim, Ha Seon; Kim, Steven; Kim, Sung Kyeom | Kyungpook Natl Univ, Coll Agr & Life Sci, Dept Hort Sci, Daegu 41566, South Korea; Univ Calif Davis, Dept Plant Sci, 1636 East Alisal St, Salinas, CA 93905 USA; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea; Calif State Univ, Dept Math & Stat, Seaside, CA 93955 USA | Kim, Steven/HSH-9295-2023; Kim, Sung Kyeom/AAD-9230-2019; Kim, Dong/G-7392-2017 | 57220893546; 15760138600; 57220895028; 57220890640; 55243558900; 50262290200 | cata1119@knu.ac.kr;vdskim@ucdavis.edu;shonlysr@knu.ac.kr;dlfurgml@knu.ac.kr;stkim@csumb.edu;skkim76@knu.ac.kr; | HORTICULTURAE | HORTICULTURAE | 2311-7524 | 7 | 2 | SCIE | HORTICULTURE | 2021 | 2.923 | 18.1 | 2.49 | 2025-07-30 | 21 | 26 | Fragaria × ananassa; plant size; flowering; fresh weight; ratio of red and far-red lights | Flowering; Fragaria × ananassa; Fresh weight; Plant size; Ratio of red and far-red lights | English | 2021 | 2021-02 | 10.3390/horticulturae7020030 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Description of Sudden Polarization in the Excited Electronic States with an Ensemble Density Functional Theory Method | Sudden polarization (SP) is one of the manifestations of electron transfer in the electronically excited states of molecules. Proposed initially to explain the unusual reactivity of photoexcited olefins, SP often occurs in the excited states of molecules possessing strongly correlated diradical ground state. Theoretical description of SP involves mixing between the singly excited and the doubly excited zwitterionic states, which makes it inaccessible with the use of the popular linear-response time-dependent density functional theory methods. In this work, an extended variant of the state-interaction state-averaged spinrestricted ensemble-referenced Kohn-Sham (SI-SA-REKS, or SSR) method is applied to study SP in a number of organic diradical systems. To this end, the analytical derivative formalism is derived and implemented for the SSR(3,2) method (see the main text for explanation of the acronym), which enables the automatic geometry optimization and obtains the relaxed density matrices as well as the electron binding energies and respective Dyson's orbitals. Application of the new method to SP in the lowest singlet excited state of ethylene agrees with the results obtained previously with the use of multireference methods of wavefunction theory. A number of interesting manifestations of SP are observed, such as the charge transfer in photoexcited tetramethyleneethene (TME) diradical mediated by the vibrational motion and conductivity switching in the excited state of a donor-acceptor dyad placed in an external electric field. | Filatov, Michael; Lee, Seunghoon; Choi, Cheol Ho | CALTECH, Div Chem & Chem Engn, Pasadena, CA 91125 USA; Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea | Choi, Cheol Ho/AAA-4705-2020; Lee, Seunghoon/AAB-4846-2021 | 7005134246; 57194591254; 7402958948 | mike.filatov@gmail.com;cheolho.choi@gmail.com; | JOURNAL OF CHEMICAL THEORY AND COMPUTATION | J CHEM THEORY COMPUT | 1549-9618 | 1549-9626 | 17 | 8 | SCIE | CHEMISTRY, PHYSICAL;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2021 | 6.578 | 18.1 | 0.66 | 2025-07-30 | 11 | 11 | SELF-CONSISTENT-FIELD; KOHN-SHAM METHOD; CIS-TRANS PHOTOISOMERIZATION; AB-INITIO; GROUND-STATE; TETRAMETHYLENEETHANE TME; IONIZATION-POTENTIALS; EXCITATION-ENERGIES; WAVE-FUNCTIONS; HARTREE-FOCK | English | 2021 | 2021-08-10 | 10.1021/acs.jctc.1c00479 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Effects of 1-Methylcyclopropene Treatment on Fruit Quality during Cold Storage in Apple Cultivars Grown in Korea | The effect of 1-methylcyclopropene (1-MCP) treatment on improving the storability of four apple cultivars ('Hwangok', 'Picnic', 'Gamhong', and 'Fuji') was investigated by analyzing the physiological and biochemical factors associated with their postharvest quality attributes. The flesh firmness, titratable acidity, and soluble solids content of the cultivars were higher in treated fruits than untreated fruits, while the opposite results were observed for ethylene production. In the treated fruits, the traits affected by 1-MCP varied depending on the cultivars used. Higher firmness and lower ethylene production were observed in the 'Hwangok' and 'Picnic' than 'Gamhong' and 'Fuji' cultivars. However, 1-MCP only affected weight loss in the 'Gamhong' cultivar, while the sugar content was affected in all of the cultivars except 'Hwangok'. When analyzing cell wall hydrolase activities, 1-MCP differently affected the activities (beta-galactosidase, alpha-galactosidase, beta-glucosidase, alpha-mannosidase, beta-xylosidase, and beta-arabinosidase), with greater effects in the 'Fuji' and 'Picnic' cultivars and moderate effects in the 'Gamhong' and 'Hwangok' cultivars. In this study, the suppression of ethylene production by 1-MCP was positively associated with a transcriptional decrease in the ethylene biosynthesis genes MdACS1 and MdACO1. Overall, this study suggests that 1-MCP distinctly enhanced the storability of all apple cultivars, with a greater effect on 'Hwangok'. | Yoo, Jingi; Win, Nay Myo; Mang, Hyunggon; Cho, Young-Je; Jung, Hee-Young; Kang, In-Kyu | Washington State Univ, Tree Fruit Res & Extns Ctr, Wenatchee, WA 98801 USA; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Natl Inst Hort & Herbal Sci, Apple Res Inst, RDA, Gunwi 39000, South Korea; Seoul Natl Univ, Plant Immun Res Ctr, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea | Mang, Hyung-Gon/AGK-3411-2022 | 56818324500; 42462548000; 7005904004; 55265396300; 7403029383; 56577308800 | jingi.yoo@wsu.edu;naymyo329@gmail.com;skymang6@snu.ac.kr;yjcho@knu.ac.kr;heeyoung@knu.ac.kr;kangik@knu.ac.kr; | HORTICULTURAE | HORTICULTURAE | 2311-7524 | 7 | 10 | SCIE | HORTICULTURE | 2021 | 2.923 | 18.1 | 1.62 | 2025-07-30 | 13 | 18 | apple; 1-methylcyclopropene; ethylene; flesh firmness; storability; relative gene expression | CELL-WALL METABOLISM; ETHYLENE BIOSYNTHESIS; DEGRADING ENZYMES; EXPRESSION; 1-MCP; GENES; PERCEPTION; RESPONSES; TEMPERATURE; ATTRIBUTES | 1-methylcyclopropene; Apple; Ethylene; Flesh firmness; Relative gene expression; Storability | English | 2021 | 2021-10 | 10.3390/horticulturae7100338 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Efficacy of an Eco-Friendly Bloom Thinning Formulation on Mango Trees and Its Olfactory Effect on an Insect Pollinator, Apis mellifera | In various orchard fruit trees, thinning of blossoms and fruits is important to increase fruit size and quality and to promote a new bloom in the following season. Several chemical thinning agents are currently commercially available, but they are inconsistent and produce side effects in crop plants and insect pollinators. Because of environmental concerns, developing alternative eco-friendly bloom thinning agents is necessary. We developed an eco-friendly bloom thinning formulation (BTF) using minerals and extracts of various medicinal plants. Our BTF spray (0.1%, w/v) decreased the number of fruits per tree (46.5%) and fruit yield per tree (81.5%) but increased the fruit weight (196.8%) compared with the control treatment; the spray induced a small number of larger mango fruits in the treated trees. We also investigated the effect of BTF on the olfactory behavior of Apis mellifera L. (Hymenoptera, Apidae), a major insect pollinator. We analyzed the behavioral changes of adult workers at two different concentrations (0.1% and 1%) of nine different BTF spray components using a Y-tube olfactometer. The behavioral responses of honey bees to nine BTF components showed significant differences. However, honey bees showed no clear attraction or repellent behavior towards the tested BTF components. Our results suggest that the newly developed eco-friendly BTF is practically applicable in mango orchards without interrupting honey bee behavior. | Son, Tae-Kwon; Mostafiz, Md Munir; Hwang, Hwal-Su; Thanh, Nguyen Truong; Lee, Kyeong-Yeoll | Kyungpook Natl Univ, Coll Agr & Life Sci, Dept Farm Management, 80,Daehak ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Agr & Life Sci, Sch Appl Biosci, 80,Daehak ro, Daegu 41566, South Korea; Vietnam Enasa JSC, Plant Protect Res Inst, 26,Chung Cu 8X PLUS,Q 12, Hochiminh 729930, Vietnam; Kyungpook Natl Univ, Inst Agr Sci & Technol, 80,Daehak Ro, Daegu 41566, South Korea | Mostafiz, Md.

In this review, various physical and chemical etching methods, specifically developed for nanocrystal systems, as well as their advantages and disadvantages, are introduced. The surface changes in the etched nanocrystals are discussed in view of their impact on catalytic activity and stability to understand the relationship between the nanosurface and catalytic performance. Furthermore, we discuss the standing challenges and provide future research directions in this relevant field, which would lead to fruitful outcomes in developing highly stable and active electrocatalysts for sustainable energy technologies. | Choi, Songa; Park, Yeji; Kim, Hee Jin; Choi, Sang-Il; Lee, Kwangyeol | Korea Univ, Dept Chem, Seoul 02841, South Korea; Korea Univ, Res Inst Natl Sci, Seoul 02841, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea | ; Choi, Sang-Il/N-7571-2013; Choi, Sang-Il/AGR-1133-2022; Kim, Hee Jin/I-3252-2017; Lee, Kwangyeol/A-9269-2010 | 57208751493; 57215560821; 57193334513; 56167600800; 8510322900 | sichoi@knu.ac.kr;kylee1@korea.ac.kr; | MATERIALS CHEMISTRY FRONTIERS | MATER CHEM FRONT | 2052-1537 | 5 | 11 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2021 | 8.683 | 18.1 | 0.17 | 2025-07-30 | 10 | 10 | Catalyst activity; Electrocatalysis; Electrocatalysts; Nanocatalysts; Nanocrystals; Surface structure; Active site; Catalytic performance; Chemical etching; Future research directions; Highly stables; Surface changes; Sustainable energy technology; Etching | English | 2021 | 2021-06-07 | 10.1039/d1qm00233c | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Fruit Quality Attributes of 'Arisoo' and 'Picnic' Apples as Influenced by 1-Methylcyclopropene Concentration and Its Application Frequency during Cold Storage | The efficacy of 1-methylcyclopropene (1-MCP) in maintenance of apple fruit quality can differ depending on apple cultivar, ethylene content at harvest, 1-MCP concentration, the interval between harvest and 1-MCP application, and the number of applications. In this study, we investigated whether the 1-MCP concentration and its application frequency differently affected fruit quality attributes of the two new apple cultivars 'Arisoo' and 'Picnic'. The fruits were treated with 1-MCP (as single or double treatments) at the rate of 0 mu L L-1 (control), 0.5 mu L L-1, 1 mu L L-1, 0.5 + 0.5 mu L L-1, and 1 + 1 mu L L-1 for 18 h, and they were stored at 0 & DEG;C up to six months. Comparatively, the fruit qualities of 1-MCP treated fruits were higher than that of the control during cold storage, with a higher suppression of internal ethylene content and a slower reduction of titratable acidity in 1-MCP treatments than the controls throughout the cold storage in both cultivars, regardless of the concentration and number of applications. Reduction of fruit firmness and soluble solid contents were maintained by single application of 0.5 mu L L-1 1-MCP in 'Arisoo' apple, while double application of 0.5 + 0.5 mu L L-1 was needed in 'Picnic' cultivar. The effective concentration for weight-loss reduction was found to be the single application of 1 mu L L-1 1-MCP in both 'Arisoo' and 'Picnic'. Conclusively, 1-MCP as single treatment at the rate of 0.5 mu L L-1 could be sufficient in inhibiting ethylene action and maintaining fruit quality losses during cold storage, particularly in 'Arisoo'. However, double application of 1-MCP might be necessary for some quality attributes in 'Picnic' apple. | Kwon, Jung-Geun; Yoo, Jingi; Win, Nay Myo; Maung, The-Thiri; Naing, Aung Htay; Kang, In-Kyu | Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Washington State Univ, Fruit Res & Extens Ctr, Wenatchee, WA 98801 USA; Natl Inst Hort & Herbal Sci, RDA, Apple Res Inst, Gunwi 39000, South Korea; Kongju Natl Univ, Dept Food Sci & Technol, Chungnam 32439, South Korea | Naing, Aung Htay/AAF-4277-2019 | 57211404168; 56818324500; 42462548000; 57211713919; 37112768100; 56577308800 | jingi.yoo@wsu.edu;naymyo329@gmail.com;thiriyau08@gmail.com;kangik@knu.ac.kr; | HORTICULTURAE | HORTICULTURAE | 2311-7524 | 7 | 11 | SCIE | HORTICULTURE | 2021 | 2.923 | 18.1 | 0.87 | 2025-07-30 | 5 | 8 | apple; 1-methylcyclopropene; ethylene; fruit quality attributes; storage | ETHYLENE; 1-MCP; DISORDERS; HYDROLASES; RECEPTOR | 1-methylcyclopropene; Apple; Ethylene; Fruit quality attributes; Storage | English | 2021 | 2021-11 | 10.3390/horticulturae7110477 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | How Beneficial Is the Explicit Account of Doubly-Excited Configurations in Linear Response Theory? | In different branches of time-dependent density functional theory (TDDFT), the static and dynamic electron correlation enters in different ways. The standard spin-conserving linear response (LR-TDDFT) methodology includes explicitly the contributions of the singly-excited configurations; however, it relies on an implicit account of the electron correlation through an (approximate) exchange-correlation (XC) functional. In the mixed-reference spin-flip TDDFT (MRSF-TDDFT), a number of doubly-excited (DE) configurations are explicitly included in the description of their response states. Here, the importance of the explicit account of DE is investigated for the lowest four excited singlet states of all-trans-polyenes up to C24H26. For the optically bright 1B(u)(+) state, the DE contribution in MRSF-TDDFT approaches 10% with the increasing system size. For the optically dark 2A(g)(-) state, the DE contribution increases from ca. 13% (C4H6) to nearly 30% (C24H26). An even more considerable DE contribution (similar to 50%) is observed in the higher 1B(u)(-) states. As LRTDDFT misses these contributions entirely, its ability to accurately describe the excited states is limited by the XC functional. The hybrid XC functionals with a small fraction of the exact exchange, e.g., B3LYP, may mimic certain effects of DE through the self-interaction error (SIE). However, the description of the 1B(u)(+) state by LR-TDDFT remains poor. On the other hand, MRSF-TDDFT can flexibly take an implicit (through the XC functional) and an explicit (through DE) account of the electron correlation, which enables a more balanced description of various types of the excited states regardless of their character, thus reducing the chances of failure. | Horbatenko, Yevhen; Lee, Seunghoon; Filatov, Michael; Choi, Cheol Ho | Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea; CALTECH, Div Chem & Chem Engn, Pasadena, CA 91125 USA | Choi, Cheol Ho/AAA-4705-2020; Lee, Seunghoon/AAB-4846-2021 | 37080896900; 57194591254; 7005134246; 7402958948 | mike.filatov@gmail.com;cheolho.choi@gmail.com; | JOURNAL OF CHEMICAL THEORY AND COMPUTATION | J CHEM THEORY COMPUT | 1549-9618 | 1549-9626 | 17 | 2 | SCIE | CHEMISTRY, PHYSICAL;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2021 | 6.578 | 18.1 | 1.25 | 2025-07-30 | 24 | 24 | article; density functional theory | English | 2021 | 2021-02-09 | 10.1021/acs.jctc.0c01214 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Mixed-Reference Spin-Flip Time-Dependent Density Functional Theory (MRSF-TDDFT) as a Simple yet Accurate Method for Diradicals and Diradicaloids | Due to their multiconfigurational nature featuring strong electron correlation, accurate description of diradicals and diradicaloids is a challenge for quantum chemical methods. The recently developed mixed-reference spin-flip (MRSF)-TDDFT method is capable of describing the multiconfigurational electronic states of these systems while avoiding the spin-contamination pitfalls of SF-TDDFT. Here, we apply MRSF-TDDFT to study the adiabatic singlet-triplet (ST) gaps in a series of well-known diradicals and diradicaloids. On average, MRSF displays a very high prediction accuracy of the adiabatic ST gaps with the mean absolute error (MAE) amounting to 0.14 eV. In addition, MRSF is capable of accurately describing the effect of the Jahn-Teller distortion occurring in the trimethylenemethane diradical, the violation of the Hund rule in a series of the didehydrotoluene diradicals, and the potential energy surfaces of the didehydrobenzene (benzyne) diradicals. A convenient criterion for distinguishing diradicals and diradicaloids is suggested on the basis of the easily obtainable quantities. In all of these cases, which are difficult for the conventional methods of density functional theory (DFT), MRSF shows results consistent with the experiment and the high-level ab initio computations. Hence, the present study documents the reliability and accuracy of MRSF and lays out the guidelines for its application to strongly correlated molecular systems. | Horbatenko, Yevhen; Sadiq, Saima; Lee, Seunghoon; Filatov, Michael; Choi, Cheol Ho | Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea; CALTECH, Div Chem & Chem Engn, Pasadena, CA 91125 USA | ; Lee, Seunghoon/AAB-4846-2021; Choi, Cheol Ho/AAA-4705-2020; Sadiq, Saima/JAN-6421-2023 | 37080896900; 59029170800; 57194591254; 7005134246; 7402958948 | mike.filatov@gmail.com;cheolho.choi@gmail.com; | JOURNAL OF CHEMICAL THEORY AND COMPUTATION | J CHEM THEORY COMPUT | 1549-9618 | 1549-9626 | 17 | 2 | SCIE | CHEMISTRY, PHYSICAL;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2021 | 6.578 | 18.1 | 3.16 | 2025-07-30 | 56 | 55 | English | 2021 | 2021-02-09 | 10.1021/acs.jctc.0c01074 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Sucrose Enhances Anthocyanin Accumulation in Torenia by Promoting Expression of Anthocyanin Biosynthesis Genes | We examined the effects of different sucrose concentrations (3%, 5%, and 7%) on anthocyanin accumulation and plant growth in wild type (WT) and transgenic (T-2) torenia cultivar "Kauai Rose" overexpressing the anthocyanin regulatory transcription factors B-Peru + mPAP1 or RsMYB1. Sucrose increased anthocyanin production in both WT and transgenic plants, with higher anthocyanin production in transgenic plants compared to WT plants. Higher sucrose concentrations increased production of anthocyanin in transgenic and WT plants, with increased anthocyanin production associated with increased expression of anthocyanin biosynthesis genes. Higher sucrose concentrations reduced growth of WT and transgenic plants. Our results indicate that sucrose enhances anthocyanin production in torenia by regulating anthocyanin biosynthesis genes. | Naing, Aung Htay; Xu, Junping; Park, Kyeung Il; Chung, Mi Young; Kim, Chang Kil | Kyungpook Natl Univ, Dept Hort, Daegu 41566, South Korea; Yeungnam Univ, Dept Hort & Life Sci, Gyongsan 38541, South Korea; Suncheon Natl Univ, Dept Agr Educ, Sunchon 57922, South Korea | Naing, Aung Htay/AAF-4277-2019 | 37112768100; 56677024300; 7408066185; 24821361600; 7409880701 | aunghtaynaing2005@gmail.com;liluo@naver.com;pki0217@yu.ac.kr;queen@sunchon.ac.kr;ckkim@knu.ac.kr; | HORTICULTURAE | HORTICULTURAE | 2311-7524 | 7 | 8 | SCIE | HORTICULTURE | 2021 | 2.923 | 18.1 | 0.97 | 2025-07-30 | 10 | 12 | anthocyanin; gene expression; plant growth; sucrose; transgenic plant | TRANSCRIPTION FACTORS; SUGAR; INDUCTION; REQUIRES; PETUNIA; BIOMASS; GROWTH | Anthocyanin; Gene expression; Plant growth; Sucrose; Transgenic plant | English | 2021 | 2021-08 | 10.3390/horticulturae7080219 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
