| ○ | ○ | Article | Analysis of coffee bean with laser desorption ionization high-resolution mass spectrometry | This study evaluates the application of laser desorption ionization high-resolution mass spectrometry (LDI-HRMS) to identify coffee components. The coffee analysis was performed based on origins, roasting temperatures, and extraction methods. The LDI-HRMS experimental results were compared with electrospray ionization (ESI) HRMS analysis, which revealed major compositional differences of coffee ingredients between LDI and ESI data. It was also observed that bitter components in coffee increased with the increasing roasting temperature, and espresso was found to have more carbohydrate-derived compounds. This study clearly shows that coffee components can efficiently be identified with LDI. Moreover, a more systematic database can be constructed by combining it with LDI-imaging because LDI is simple, fast, and requires small amount sample consumption. | Cho, Eunji; Acter, Thamina; Uddin, Nizam; Kim, Sunghwan | Kyungpook Natl Univ, Mass Spectrometry Based Convergence Res Inst, 80 Daehak Ro, Daegu 41566, South Korea; East West Univ, Dept Math & Phys Sci, A-2 Jahurul Islam Ave, Dhaka 1212, Bangladesh; Daffodil Int Univ, Fac Allied Hlth Sci, Dept Nutr & Food Engn, Dhaka, Bangladesh; Kyungpook Natl Univ, Dept Chem, Daegu, South Korea; Green Nano Mat Res Ctr, Daegu, South Korea | Uddin, Dr. Nizam/N-3536-2014; Kim, Sunghwan/HKN-9812-2023; Uddin, Nizam/N-3536-2014 | 55863428700; 56768064900; 57188533756; 57203772967 | aktermina10@ewubd.edu;sunghwank@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0 | 2025-06-25 | 0 | 0 | coffee; component analysis; high-resolution mass spectrometry; laser desorption ionization | LIQUID-CHROMATOGRAPHY; MOLECULAR-LEVEL; ONLINE ANALYSIS; ARABICA COFFEE; CRUDE-OIL; DISCRIMINATION; ROBUSTA; ACID; MS; QUANTIFICATION | coffee; component analysis; high-resolution mass spectrometry; laser desorption ionization | Electrospray ionization; Mass spectrometry; Application of laser; Coffee analysis; Coffee beans; Compositional difference; Desorption ionization; Extraction method; High resolution mass spectrometry; Laser desorption; Roasting temperature; Simple++; Desorption | English | 2022 | 2022-03 | 10.1002/bkcs.12477 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Dibromorhodamine-based photoredox catalysis under visible light for the colorimetric detection of Hg(II) ion | We demonstrated a colorimetric readout of Hg(II) ion through visible-light-induced polymerization, initiated by an Hg(II)-responsive photoredox initiator/catalyst under aerobic conditions. Thiosemicarbazide-functionalized 4 ',5 '-dibromorhodamine was synthesized as a stimuli-responsive photoredox catalyst. The rhodamine derivatives bearing thiosemicarbazide have been known as fluorogenic probes of Hg(II) ion with excellent sensitivity and selectivity. In this work, we incorporated a heavy halogen atom (i.e., Br) onto the xanthene core ring of the rhodamine derivative to improve the photoredox catalytic performance of rhodamine 6G, which exhibits a low catalytic performance, presumably due to the poor quantum yield of intersystem crossing. Thus, this photoredox catalyst led to the formation of a hydrogel with Hg(II) ion in a concentration of 10 mu M, as the catalyst initiated free-radical polymerization of poly(ethylene glycol) diacrylate and N-vinylpyrrolidone with triethanolamine under visible light for 1 min. | Nganga, Joseph B.; Jung, Young Jae; Choi, Won Oh; Lee, Hyosun; Lee, Jeong Tae; Lee, Jungkyu K. | Kyungpook Natl Univ, Dept Chem, Daegu 37224, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 37224, South Korea; Hallym Univ, Dept Chem, Chunchon 24252, South Korea; Hallym Univ, Inst Appl Chem, Chunchon 24252, South Korea | 57226016306; 57211604984; 57760569800; 15750846000; 8911413500; 8312040000 | jtshl@hallym.ac.kr;jkl@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0.06 | 2025-06-25 | 1 | 1 | dibromorhodamine; naked eye detection; Photoredox catalysis; polymerization based signal amplification | POLYMERIZATION REACTIONS | dibromorhodamine; naked eye detection; Photoredox catalysis; polymerization based signal amplification | Amines; Catalysis; Catalysts; Color; Colorimetry; Eye protection; Free radical polymerization; Free radicals; Light; Mercury compounds; Polyethylene glycols; Catalytic performance; Dibromorhodamine; Naked-eye detection; Photoredox catalysis; Polymerization based signal amplification; Rhodamine; Signal amplifications; Thiosemicarbazides; Visible light; ]+ catalyst; Ions | English | 2022 | 2022-07 | 10.1002/bkcs.12547 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Excess dopant effect in platinum-based alloys toward the oxygen electroreduction reaction | Doping the PtNi octahedra with trace amount of transition metals has recently been shown to significantly improve the activity and durability of the oxygen reduction reaction (ORR). However, the role of excessive amounts of doped elements on ORR performance is unclear. In this work, PtNi octahedra were synthesized with and without excess Mo dopant. Also, spherical PtNi nanoparticles containing excess Co dopant were synthesized. The ORR performance revealed that PtNiMo octahedra and PtNiCo nanoparticles showed inferior ORR activities compared to bimetallic PtNi octahedra. Based on the electrochemical analysis, we found that unfavorable oxygen-binding strengths of PtNiMo and PtNiCo catalysts decrease the ORR performances. | Kabiraz, Mrinal Kanti; Kim, Hee Jin; Hong, Youngmin; Chang, Qiaowan; Choi, Sang-Il | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nanomat Res Ctr, Daegu 41566, South Korea; Columbia Univ, Dept Chem Engn, New York, NY 10027 USA; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu, South Korea | Kabiraz, Mrinal/AAE-6381-2020; Choi, Sang-Il/AGR-1133-2022; Chang, Qiaowan/EHZ-6021-2022 | 57201400780; 57193334513; 57194557373; 56524911100; 56167600800 | sichoi@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0.49 | 2025-06-25 | 8 | 8 | dopant; excess metal; nanocatalyst; oxygen reduction reaction; platinum-nickel | CATALYSTS; MEMBRANE; EVOLUTION | dopant; excess metal; nanocatalyst; oxygen reduction reaction; platinum-nickel | Binary alloys; Electrolytic reduction; Nanoparticles; Nickel; Oxygen; Platinum alloys; Synthesis (chemical); Ternary alloys; Trace elements; Dopants effects; Doped elements; Excess metal; Nano-catalyst; Oxygen electroreduction reactions; Oxygen reduction reaction; Platinum-nickel; Reaction performance; Synthesised; Trace amounts; Nanocatalysts | English | 2022 | 2022-09 | 10.1002/bkcs.12588 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | Particle size effect on the catalytic properties of zeolitic imidazolate frameworks | Zeolitic imidazolate frameworks (ZIFs) possess unique structural, textural, and physico-chemical properties and, therefore, they are promising materials for the synthesis of catalysts. The presence of acidic and basic sites in the structure of ZIFs and the possibility of controlling their number and accessibility offer various ways of using ZIFs in acid-base catalysis. Domestic and foreign works devoted to the study of the catalytic properties of ZIFs in reactions of the acid-base type and published within the recent 15 years are reviewed. Special attention is given to the effect of the crystal size of ZIFs on their catalytic properties in such reactions as condensation, cyclization, and esterification. The advantages and drawbacks of ZIFs as catalysts and the main questions that arise during practical use are considered. | Timofeeva, M. N.; Lukoyanov, I. A.; Panchenko, V. N.; Jhung, S.

| ○ | ○ | Article | Peroxidase-like activity of an azamacrocyclic Ni(II) complex | Peroxidase-like activity of an azamacrocyclic Ni(II) complex, [Ni(II)(DMDAC)](2+) (DMDAC = 1,8-dimethyl-1,3,6,8,10,13-hexaaza-cyclotetradecane = 1,8-dimethyl diazacyclam), was investigated by observing the oxidation of 2,2 '-azinobis(3-ethylbenzothiazoline)-6-sulfonic acid (ABTS) in the presence of H2O2. UV/Vis and electron paramagnetic resonance spectral changes obtained from the mixture solution of [Ni(II)(DMDAC)](ClO4)(2), ABTS, and H2O2 indicated that both ABTS and its oxidized form, ABTS(+center dot), were the substrates of the peroxidase-like activity of [Ni(II)(DMDAC)](2+). Current work and previously reported experimental and theoretical works on the peroxidase-like activity of azamacrocyclic Ni(II) complexes suggest that these kind of macrocyclic Ni(II) complexes can generally exhibit peroxidase-like activity in aqueous solution and the catalytic cycle proceeds through the heterolytic cleavage of the O-OH bond in a Ni(II)-hydroperoxo species. | Cho, Jang-Hoon; Kim, Sunghwan; Lee, Hong-In | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Res Ctr, Daegu 41566, South Korea | Lee, Hong-In/IXN-3185-2023; Kim, Sunghwan/HKN-9812-2023 | 8402955600; 57203772967; 8509535000 | leehi@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0.19 | 2025-06-25 | 3 | 3 | azamacrocyclic Ni(II) complex; Ni-oxo complex; peroxidase activity | GLUTATHIONE-PEROXIDASE; VANADIUM BROMOPEROXIDASE; MANGANESE-PEROXIDASE; MECHANISTIC INSIGHTS; CATALYTIC-ACTIVITY; HYDROGEN-PEROXIDE; OXIDATION; HYDROPEROXIDE; NICKEL(II); REACTIVITY | azamacrocyclic Ni(II) complex; Ni-oxo complex; peroxidase activity | Catalyst activity; Paramagnetic resonance; 'current; Azamacrocyclic; Catalytic cycles; Heterolytic cleavage; Macrocyclics; Mixture solution; Peroxidase-like activities; Spectral change; Sulphonic acids; Nickel compounds | English | 2022 | 2022-03 | 10.1002/bkcs.12493 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Review | Recent research trends in fluorescent reporters-based lateral flow immunoassay for protein biomarkers specific to acute myocardial infarction | A rapid and sensitive method is urgently required for the detection of acute myocardial infarction (AMI), a major cause of death globally. As a user-friendly diagnostic platform, the lateral flow immunoassay (LFIA) has been considered as a rapid and low-cost tool for point-of-care testing. Among the available LFIAs, fluorescent nanoparticles have been widely used as reporters to improve the sensitivity of detection targets. This review describes the basic principle of fluorescence-based LFIA and various fluorescent nanoparticles used as a signal readout. Recently, various studies on fluorescent reporters-based LFIAs for diagnosing potential AMI have been outlined by determining the level of AMI-specific protein biomarkers, including cardiac troponins I and T, heart-type fatty acid-binding protein, myoglobin, brain natriuretic peptide, suppression of tumorigenicity 2, creatine kinase-MB, and C-reactive protein. The challenges of the used fluorescent reporters in LFIA are discussed to achieve affordable and excellent performances for clinical applications. | Supianto, Mulya; Lee, Hye Jin | Kyungpook Natl Univ, Dept Chem, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, 80 Daehakro, Daegu 41566, South Korea | Supianto, Mulya/KIH-9760-2024; LEE, HYEJIN/W-1345-2018 | 57304127400; 56569175200 | hyejinlee@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0.15 | 2025-06-25 | 9 | 8 | acute myocardial infarction; biomarkers; fluorescence; lateral flow immunoassay; nanoparticles | ACID-BINDING PROTEIN; QUANTUM DOTS; ASSAY | Biomarkers; Cardiology; Fatty acids; Fluorescence; Immunology; Proteins; Acute myocardial infarction; Causes of death; Fluorescent nanoparticles; Fluorescent reporter; Lateral flow immunoassay; Rapid method; Recent researches; Research trends; Sensitive method; User friendly; Nanoparticles | English | 2022 | 2022-01 | 10.1002/bkcs.12430 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Synthesis and characterization of β-carotene-loaded albumin nanoparticles by high-speed homogenizer | beta-Carotene (BC) is a strong antioxidant, but its therapeutic application has been limited by its poor aqueous solubility. Protein-based nanoparticles (NPs) have been used to increase the aqueous solubility of hydrophobic drugs. In this study, bovine serum albumin (BSA) was used to prepare NPs to encapsulate BC using a high-speed homogenizer. After homogenization, BC-BSA-NPs were formed and the encapsulated BC was dissolved in phosphate-buffered saline at pH 7.4. Various characterization methods, including dynamic light scattering, transmission electron microscopy, and spectrophotometry, indicated that BC-BSA-NPs were spherical with an average size of 112 nm and encapsulated BC with high efficiency. BC encapsulated in NPs was stable during the preparation process and was continuously released in PBS at 37 degrees C for 3 days. The 2,2-diphenyl-1-picrylhydrazyl and ferric reducing antioxidant power assays demonstrated good antioxidant activity of BC-BSA-NPs. These results suggest that BSA-NPs are a promising nanocarrier for the delivery of BC. | Yang, Hye Gyeong; Yang, Eun-Ju; Park, Eun Ji; Lee, Young Jin; Safavi, Maryam Sadat; Song, Kyung-Sik; Na, Dong Hee | Chung Ang Univ, Coll Pharm, Seoul 06974, South Korea; D&D Pharmatech, Seongnam, Gyeonggi Do, South Korea; Tarbiat Modares Univ, Fac Chem Engn, Biotechnol Grp, Tehran, Iran; Kyungpook Natl Univ, Coll Pharm, Daegu, South Korea | 57194626603; 57191204368; 57760110400; 57188873692; 56533588300; 13310139000; 7103210503 | dhna@cau.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0.43 | 2025-06-25 | 7 | 7 | antioxidant activity; albumin nanoparticles; beta-carotene; in vitro release; solubilization | PROTEIN NANOPARTICLES; BOUND PACLITAXEL; SERUM-ALBUMIN; VITAMIN-A; DELIVERY; CARRIERS | albumin nanoparticles; antioxidant activity; in vitro release; solubilization; β-carotene | Antioxidants; Controlled drug delivery; High resolution transmission electron microscopy; Light scattering; Light transmission; Mammals; Nanoparticles; Synthesis (chemical); Targeted drug delivery; Albumin nanoparticles; Antioxidant activities; Bovine serum albumins; High Speed; Homogenizers; In vitro release; In-vitro; Solubilisation; Vitro release; Β-carotene; Solubility | English | 2022 | 2022-05 | 10.1002/bkcs.12509 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The effect of acrylic silane crosslinker on room-temperature cured acrylate binder for road markings | An acrylic binder with excellent physical properties is prepared using copolymer of methyl methacrylate (MMA) and butyl acrylate monomer (BAM), 2-hydroxyethyl methacrylate (2-HEMA), 3-(trimethoxysilyl)propyl methacrylate (TMSPMA), and additives. The obtained acrylic resins are subjected to a redox initiator system (ROIS) for room temperature curing. The effects of the TMSPMA concentration and [acryl-copolymer]/[2-HEMA] ratio on backbone content are studied in terms of traffic marking paint. The mechanical and morphological properties are thoroughly evaluated using universal testing machine (UTM), UV spectrum, and SEM. With increasing TMSPMA content, the adhesive strength and transmittance of the cured resins increase up to a limiting value of TMSPMA content because of the optimizing crosslink network in backbone structure. The introduction of TMSPMA may be effectively attributed to strong adhesive and high transparency of an acrylic resin series. Consequently, acrylic resins with optimal TMSPMA content can be mostly utilized as a high-performance binder in the traffic marking paint field. | Jang, Dong Gyu; Lim, Won-Bin; Bae, Ji-Hong; Lee, Ju-Hong; Min, Jin-Gyu; Kim, Ju-Won; Yoon, Keun-Byoung; Huh, PilHo | Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Pusan Natl Univ, Dept Polymer Sci & Engn, Busan 46241, South Korea | 57731689500; 57215429636; 57197818028; 57221327675; 57217687607; 57733187700; 7401607550; 6603741375 | kbyoon@knu.ackr;pilho.huh@pusan.ac.kr;kbyoon@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0.31 | 2025-06-25 | 5 | 5 | acrylic resin; optimal TMSPMA content; polymer binder; room-temperature curing; traffic marking paint | CONTROLLED RADICAL POLYMERIZATION; LINKING POLYMERIZATION; REDOX; POLYURETHANE; COATINGS; SOLVENT | acrylic resin; optimal TMSPMA content; polymer binder; room-temperature curing; traffic marking paint | Acrylic monomers; Additives; Adhesives; Curing; Esters; Paint; Road and street markings; Ultraviolet spectroscopy; 2-hydroxyethyl methacrylate; 3-(Trimethoxysilyl)propyl methacrylate; 3-trimethoxysilyl propyl methacrylates; Acrylic resins; Crosslinker; Optimal 3-(trimethoxysilyl)propyl methacrylate content; Polymer binders; Room temperature cured; Room temperature curing; Traffic marking paint; Resins | English | 2022 | 2022-08 | 10.1002/bkcs.12576 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Uncoordinated tetrazole ligands in metal-organic frameworks for proton-conductivity studies | Zr-based metal-organic frameworks (MOFs) were modified with pendant tetrazole ligands for proton conductivity studies. Although tetrazolate ligands coordinated to metal cations have been widely utilized to construct MOFs or porous coordination polymers, to date, the use of uncoordinated tetrazole groups in MOFs has been limited. In this study, a benzene-1,4-dicarboxylic acid with pendant tetrazole groups (BDC-N-4) was synthesized and used to prepare a Zr-based UiO-66 MOF using a mixed-ligand strategy. The tetrazole-functionalized UiO-66-N-4 was compared to MOFs containing other acidic functional groups (hydroxyl, carboxylic acid, and sulfonic acid) with respect to their proton conductivities and acidities (calculated pK(a)). Interestingly, UiO-66-N-4 showed a significant decrease in the activation energy with increase in the amount of added tetrazole groups, suggesting the Grotthuss proton conduction mechanism for uncoordinated tetrazole-containing MOFs. | Lee, Daeyeon; Lee, Sangho; Son, Younghu; Kim, Jun Yeong; Cha, Seungheon; Kwak, Dongmin; Lee, Jooyeon; Kwak, Jaesung; Yoon, Minyoung; Kim, Min | Chungbuk Natl Univ, Dept Chem, Cheongju 28644, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Korea Res Inst Chem Res, Infect Dis Therapeut Res Ctr, Daejeon 34114, South Korea | Son, Younghu/AAX-9531-2021; Kim, Min/Q-9608-2019 | 57680196100; 58374503000; 57216839175; 57679887000; 57678658300; 59083240100; 57205516966; 22734356700; 25222186500; 25649767300 | leejs6031@chungbuk.ac.kr;jkwak@krict.re.kr;myyoon@knu.ac.kr;minkim@chungbuk.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 43 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 1.7 | 72.2 | 0.93 | 2025-06-25 | 15 | 15 | coordination polymer; functionalization; metal-organic framework; proton conductivity; tetrazole | SULFONIC-ACID GROUPS; COORDINATION POLYMERS; UIO-66 | coordination polymer; functionalization; metal–organic framework; proton conductivity; tetrazole | Activation energy; Ligands; Metals; Coordination Polymers; Coordination-polymers; Dicarboxylic acid; Functionalizations; Metal cation; Metalorganic frameworks (MOFs); Mixed-ligands; Porous coordination polymer; Synthesised; Tetrazoles; Proton conductivity | English | 2022 | 2022-07 | 10.1002/bkcs.12539 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Anastomotic leak after minimally invasive anterior resection for rectal cancer with high versus low ligation of the inferior mesenteric artery: a study protocol for a multicentre randomized clinical trial | Background Although many efforts have been made to decrease the incidence of anastomotic leak (AL), it remains one of the most serious complications of rectal cancer surgery. Many previous studies have reported an association between the ligation level of the inferior mesenteric artery (IMA) (high or low) and the incidence of AL after rectal cancer surgery. However, we cannot draw a solid conclusion because of the low quality and heterogeneity of those studies. Therefore, this study aims to investigate the impact of the IMA ligation level on the occurrence of AL after minimally invasive anterior resection of rectal cancer. Methods/design Patients with primary rectal cancer without distant metastases will be included after screening. They will be randomly assigned (1:1) to receive high or low ligation of the IMA. The primary endpoint is AL incidence; secondary endpoints are quality of life; urinary, sexual, and defecatory functions; and 3-year disease-free survival. We hypothesized that the incidence rate of AL would be 15% and 5% in the high- and low-ligation groups, respectively. With a two-sided alpha of 0.05 and a power of 0.8, the sample size is calculated to be 314 patients (157 per group), considering a 10% dropout rate. Discussion Although many studies have compared the short- and long-term outcomes of high and low ligation of the IMA in rectal cancer surgery, it is still debatable. This trial aims to help draw a more solid conclusion regarding the association between the IMA ligation level and AL incidence after rectal cancer surgery. We also hope to contribute to standardizing the method of rectal cancer surgery in this trial. | Lee, Soo Young; Kim, Sohyun; Son, Gyung Mo; Kim, Hye Jin; Park, Soo Yeun; Park, Jun Seok; Kim, Chang Hyun; Ha, Gi Won; Lee, Kyung-Ha; Kim, Jin Soo; Bae, Ki Beom; Bae, Sung Uk; Kang, Sung Il | Chonnam Natl Univ, Hwasun Hosp, Dept Surg, Hwasun, Jeonnam, South Korea; Med Sch, Hwasun, Jeonnam, South Korea; Yeungnam Univ, Coll Med, Dept Surg, Daegu, South Korea; Pusan Natl Univ, Yangsan Hosp, Sch Med, Dept Surg, 20 Geumo Ro Mulgeum Eup, Yangsan 50612, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Colorectal Canc Ctr, Sch Med, 807 Hogukro, Daegu 40414, South Korea; Jeonbuk Natl Univ, Jeonbuk Natl Univ Hosp, Biomed Res Inst, Res Inst Clin Med, Jeonju, Jeonbuk, South Korea; Chungnam Natl Univ, Dept Surg, Chungnam Natl Univ Hosp, Daejeon, South Korea; Chungnam Natl Univ, Coll Med, Daejeon, South Korea; Chungnam Natl Univ, Sejong Hosp, Dept Surg, Daejeon, South Korea; Inje Univ, Dept Surg, Busan Paik Hosp, Coll Med,Paik Inst Clin Res, Busan, South Korea; Keimyung Univ, Sch Med, Dept Surg, Daegu, South Korea; Dongsan Med Ctr, Daegu, South Korea | Kim, chang/F-6457-2013; 손, 경모/HZJ-3181-2023; Kim, Hye/W-1059-2019; Park, Joonhong/AAZ-9885-2020; Lee, Soo Young/NFU-0636-2025; Ha, Gi/W-2026-2019; Bae, Sung/W-1915-2019 | 59055078800; 39361754400; 35741980300; 57204567554; 40561578300; 35226761100; 57214805950; 56562681000; 55548203300; 57209556084; 57223615889; 55748167300; 57191976856 | skm1711@pusan.ac.kr;hjinkim@knu.ac.kr; | TRIALS | TRIALS | 1745-6215 | 23 | 1 | SCIE | MEDICINE, RESEARCH & EXPERIMENTAL | 2022 | 2.5 | 72.4 | 0 | 2025-06-25 | 0 | 0 | Rectal cancer; Anastomotic leak; Inferior mesenteric artery ligation; Randomized controlled trial | INDEX; PRESERVATION; INSTRUMENT; EXCISION; OUTCOMES; SURGERY | Anastomotic leak; Inferior mesenteric artery ligation; Randomized controlled trial; Rectal cancer | Anastomotic Leak; Humans; Laparoscopy; Ligation; Mesenteric Artery, Inferior; Multicenter Studies as Topic; Quality of Life; Randomized Controlled Trials as Topic; Rectal Neoplasms; adult; aged; anastomosis leakage; artery ligation; Article; cancer surgery; cancer survival; clinical outcome; clinical trial protocol; confidentiality; controlled study; defecation; disease free survival; human; incidence; inferior mesenteric artery ligation; major clinical study; minimally invasive surgery; multicenter study; prospective study; quality of life; randomized controlled trial; rectum cancer; sexual function; South Korea; standardization; urinary tract function; adverse event; anastomosis leakage; inferior mesenteric artery; laparoscopy; ligation; multicenter study (topic); pathology; procedures; randomized controlled trial (topic); rectum tumor | English | 2022 | 2022-10-31 | 10.1186/s13063-022-06862-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Comprehensive modeling of the extrinsic transconductance for InxGa1-xAs/In0.52Al0.48As quantum-well high-electron-mobility transistors | This paper presents the comprehensive modeling of extrinsic transconductance (gmₑₓₜ) in the saturation regime for InxGa1-xAs/In0.52Al0.48As quantum-well (QW) high-electron-mobility transistors (HEMTs) with Lg from 10 μm to sub-100 nm, covering the ballistic and mobility relevant regimes. First, we fabricated and characterized two types of lattice matched (LM) channel In0.53Ga0.47As QW HEMTs on a 3-inch InP substrate. One of these was fully fabricated with an i-line stepper, yielding Lg from 10 μm to 0.5 μm, and the other was fabricated in a mix & match manner with a combination of an i-line stepper and an e-beam lithography equipment, where T-shaped gates were implemented using a tri-layer resist stack of ZEP520A-PMGI-ZEP520A in the e-beam lithography process. Using devices with a wide range of Lg values, we examined the transconductance (gm) characteristics in saturation and attempted to correlate them to analytical expressions capable of describing the carrier transport properties of the devices using only physical parameters, such as the gate capacitance (Cgi) apparent mobility (μnₐₚₚ), and saturation velocity (vsat), and the series resistances (Rs and Rd). In this way, we assessed the dependences of the extrinsic transconductances of the fabricated devices on their gate lengths, with the model parameters of Cgi = 0.65 μF/cm2, μnₐₚₚ = 9400 cm2/V⋅s, vsat = 4.3 × 107 cm/s and Rs = 147 Ω⋅μm. These values were observed to be well-matched with those of the physical parameters. Most importantly, we extended the proposed approach to realistically project the increase in gmₑₓₜ that could be accomplished by improving certain device parameters. © 2022 Elsevier Ltd | Yun, Seung-Won; Jo, Hyeon-Bhin; Jeong, Hyeon-Seok; Park, Wan-Soo; Yoo, Ji-Hoon; Lee, In-Geun; Kim, Tae-Woo; Tsutsumi, Takuya; Sugiyama, Hiroki; Matsuzaki, Hideaki; Kim, Dae-Hyun | School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; Department of Materials Science and Engineering, Yonsei University (YSU), South Korea; School of Electrical Engineering, University of Ulsan (UoU), South Korea; NTT Device Technology Laboratories, NTT Corporation, Japan; NTT Device Technology Laboratories, NTT Corporation, Japan; NTT Device Technology Laboratories, NTT Corporation, Japan; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea | 57221602680; 57202871742; 57200366272; 57222957219; 57545572700; 37016357200; 57203495132; 37007126500; 35417698400; 7202461821; 57212363794 | twkim78@ulsan.ac.kr; | Solid-State Electronics | SOLID STATE ELECTRON | 0038-1101 | 1879-2405 | 198 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 1.7 | 72.4 | 0 | 2025-06-25 | 0 | Compound semiconductors; Device modeing; HEMTs; III-V semiconductors; InGaAs HEMTs; Mobility; Transconductance | Electric resistance; Electron mobility; Fabrication; Gallium alloys; High electron mobility transistors; Indium alloys; Indium phosphide; Semiconducting indium; Semiconducting indium gallium arsenide; Semiconducting indium phosphide; Semiconductor alloys; Semiconductor quantum wells; Transconductance; Compound semiconductors; Comprehensive modeling; Device modeing; Extrinsic transconductance; High electron-mobility transistors; III/V semiconductors; Ingaas high-electron-mobility transistor; Mobility; Quantum-wells; III-V semiconductors | English | Final | 2022 | 10.1016/j.sse.2022.108484 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Extraction of effective mobility of In0.8Ga0.2As/In0.52Al0.48As quantum well high-electron-mobility transistors on InP substrate | In this work, we explored the effective mobility of In-rich InxGa1-xAs/In0.52Al0.48As (x > 0.53) quantum well (QW) high-electron-mobility transistors (HEMTs) on an InP substrate. Historically, the carrier transport prop-erties of these types of devices have been assessed mostly using their Hall mobility, not using the effective mobility, mainly because the excessive gate leakage current degrades and contaminates their measured capac-itance voltage (CV) characteristics. However, our recent studies on these devices achieved a significant reduction in the gate leakage current, which motivated us to explore their effective mobility. In this work, therefore, we used a conventional split CV technique to determine and analyze the effective mobility of In0.8Ga0.2As/ In0.52Al0.48As QW HEMTs. We also attempted to model the extracted effective mobility by considering three different scattering mechanisms-Coulombic scattering, phonon scattering and surface-roughness scattering- under the guidance of Matthiessen's rule. | Park, Wan-Soo; Kim, Jun-Gyu; Yun, Seung-Won; Jeong, Hyeon-Seok; Jo, Hyeon-Bhin; Kim, Tae-Woo; Tsutsumi, Takuya; Sugiyama, Hiroki; Matsuzaki, Hideaki; Kim, Dae-Hyun | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Univ Ulsan, Sch Elect Engn, Ulsan, South Korea; NTT Corp, NTT Device Technol Labs, Tokyo, Japan | ; Kim, Junghwan/AAQ-9204-2021; Kim, Yong/H-6157-2013; Jo, Hyeon Bhin/HLW-9536-2023 | 57222957219; 57203326312; 57221602680; 57200366272; 57202871742; 57203495132; 37007126500; 35417698400; 7202461821; 57212363794 | dae-hyun.kim@ee.knu.ac.kr; | SOLID-STATE ELECTRONICS | SOLID STATE ELECTRON | 0038-1101 | 1879-2405 | 197 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 1.7 | 72.4 | 0.52 | 2025-06-25 | 4 | 6 | HEMTs; Effective mobility; Compound semiconductor; III-V semiconductor; Split CV; Mobility | Compound semiconductor; Effective mobility; HEMTs; III-V semiconductor; Mobility; Split CV | Aluminum compounds; Capacitance; Electron mobility; Hall mobility; High electron mobility transistors; Indium phosphide; Leakage currents; Semiconducting indium phosphide; Semiconductor quantum wells; Substrates; Surface roughness; Capacitance voltage; Compound semiconductors; Effective mobilities; Gate-leakage current; High electron-mobility transistors; III/V semiconductors; InP substrates; Mobility; Quantum-wells; Split capacitance voltage; III-V semiconductors | English | 2022 | 2022-11 | 10.1016/j.sse.2022.108446 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Recombinant Unique Cartilage Matrix-associated Protein Potentiates Osteogenic Differentiation and Mineralization of MC3T3-E1 Cells | Objective: The relative balance of osteoblasts in bone formation and osteoclasts in bone resorption is crucial for maintaining bone health. With age, this balance between osteoblasts and osteoclasts is broken, resulting in bone loss. Anabolic drugs are continuously being developed to counteract this low bone mass. Recombinant proteins are used as biotherapeutics due to being relatively easy to produce on a large scale and are cost-effective through various expression systems. This study aimed to develop a recombinant protein that would positively impact osteoblast differentiation and mineralized nodule formation using unique cartilage matrix-associated protein (UCMA). Methods: A recombinant glutathione-S-transferase (GST)-UCMA fusion protein was generated in an E.coli system, and purified by affinity chromatography. MC3T3-E1 osteoblast cells and Osterix (Osx)-knockdown stable cells were cultured for 14 days to investigate osteoblast differentiation and nodule formation in the presence of the recombinant GST-UCMA protein. The differentiated cells were assessed by alizarin red S staining and quantitative PCR of the osteoblast differentiation marker osteocalcin. In addition, cell viability in the presence of the recombinant GST-UCMA protein was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and cell adhesion assay. Results: The isolation of both purified recombinant GST-only and GST-UCMA proteins were confirmed at 26 kDa and 34 kDa, respectively, by Coomassie staining and western blot analysis. Neither dose-dependent nor time-dependent presence of recombinant GST-UCMA affected MC3T3-E1 cell viability. However, MC3T3-E1 cell adhesion to the recombinant GST-UCMA protein increased dose-dependently. Osteoblast differentiation and nodule formation were promoted in both MC3T3-E1 osteoblast cells and Osx-knockdown stable cells when cultured in the presence of recombinant GST-UCMA protein. Conclusion: A recombinant GST-UCMA protein induces osteogenic differentiation and mineralization, suggesting its potential use as an anabolic drug to increase low bone mass in osteoporotic patients. | Lee, Yeon-Ju; Ju, Hyeon Yeong; Park, Seung-Yoon; Ihn, Hye Jung; Park, Eui Kyun; Kim, Jung-Eun | Kyungpook Natl Univ, Sch Med, Dept Mol Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Dept Biomed Sci, BK21 Four KNU Convergence Educ Program Biomed Sci, Daegu 41944, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu 41944, South Korea; Dongguk Univ, Sch Med, Dept Biochem, Gyeongju 38066, South Korea; Kyungpook Natl Univ, IHBR, Sch Dent, Dept Oral Pathol & Regenerat Med, Daegu 41940, South Korea | 57199022123; 57730449200; 8627776300; 56421724400; 37071072400; 57209054588 | kjeun@knu.ac.kr; | CURRENT MOLECULAR MEDICINE | CURR MOL MED | 1566-5240 | 1875-5666 | 22 | 8 | SCIE | MEDICINE, RESEARCH & EXPERIMENTAL | 2022 | 2.5 | 72.4 | 0.35 | 2025-06-25 | 4 | 4 | UCMA protein; GST-fusion; recombinant; osteoblast; differentiation; mineralization | PARATHYROID-HORMONE 1-34; OSTEOBLAST DIFFERENTIATION; POSTMENOPAUSAL WOMEN; BONE; OSTEOPOROSIS; EXPRESSION; OSTERIX; UCMA; FRACTURES; PLACEBO | differentiation; GST-fusion; mineralization; osteoblast; recombinant; UCMA protein | Cartilage; Cell Differentiation; Humans; Matrilin Proteins; Osteoblasts; Osteocalcin; Osteogenesis; alizarin red s; nuclear matrix protein; matrilin; osteocalcin; affinity chromatography; animal cell; animal experiment; animal model; Article; bone development; bone regeneration; cartilage; cell adhesion assay; cell differentiation; cell proliferation; cell viability; controlled study; MC3T3 cell line; mineralization; mouse; MTT assay; nonhuman; osteoblast; protein expression; RNA isolation; Western blotting; cartilage; human; metabolism; osteoblast | English | 2022 | 2022 | 10.2174/1566524021666211117144314 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Vertical homo-junction In0.53Ga0.47As tunneling field-effect transistors with minimum subthreshold swing of 52 mV/decade | In this work, we successfully fabricated vertical homo-junction In0.53Ga0.47As tunneling field-effect transistors (TFETs) by a top-down approach. We particularly focused on recovery of the sidewall damage induced during dry etching of the In0.53Ga0.47As layer. The recovery steps comprised a series of digital etching cycles, short wet etching of the In0.53Ga0.47As layer, and (NH4)2S-based treatment. The fabricated device with a gate length of 100 nm exhibited a minimum subthreshold swing of 52 mV/decade at room temperature and an average subthreshold swing of 60 mV/decade over more than two decades of drain current. We also fabricated and analyzed In0.53Ga0.47As metal-oxidesemiconductor capacitors and metal-oxidesemiconductor field-effect transistors to investigate the effect of the S-treatment on their electrical characteristics. © 2022 Elsevier Ltd | Baek, Ji-Min; Kim, Hyo-Jin; Yoo, Ji-Hoon; Shin, Ju-Won; Shin, Ki-Yong; Amir, Walid; Ju, Gunwu; Kim, Hyung-Jun; Oh, Joohee; Kim, Hyoungsub; Kim, Tae-Woo; Kim, Dae-Hyun | School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea; School of Electrical Engineering, University of Ulsan (UoU), South Korea; School of Electrical Engineering, University of Ulsan (UoU), South Korea; School of Electrical Engineering, University of Ulsan (UoU), South Korea; Korea Institute of Science and Technology (KIST), South Korea; Korea Institute of Science and Technology (KIST), South Korea; School of Advanced Materials Science and Engineering, Sungkyunkwan University (SKKU), South Korea; School of Advanced Materials Science and Engineering, Sungkyunkwan University (SKKU), South Korea; School of Electrical Engineering, University of Ulsan (UoU), South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), South Korea | 57189694750; 57202516002; 57545572700; 57344071200; 57221120602; 57220184861; 53363788600; 57203630389; 57226750001; 55570860000; 57203495132; 57212363794 | twkim78@ulsan.ac.kr; | Solid-State Electronics | SOLID STATE ELECTRON | 0038-1101 | 1879-2405 | 197 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2022 | 1.7 | 72.4 | 0.26 | 2025-06-25 | 3 | In<sub>0.53</sub>Ga<sub>0.47</sub>As; Plasma damage; Sub-60mV/decade; Sulfur treatment; Surface recovery; Top-down; Tunneling field-effect transistors; Vertical | Drain current; Dry etching; Gallium alloys; Recovery; Sulfur; Tunnel field effect transistors; Wet etching; Homo-junctions; In0.53ga0.47as; Plasma damage; Sub-60mv/decade; Sub-threshold swing(ss); Sulfur treatment; Surface recovery; Topdown; Tunneling field-effect transistors; Vertical; Semiconductor alloys | English | Final | 2022 | 10.1016/j.sse.2022.108447 | 바로가기 | 바로가기 | 바로가기 |
