| ○ | ○ | Article | Optimizing Window Glass Design for Energy Efficiency in South Korean Office Buildings: A Hierarchical Analysis Using Energy Simulation | The world is emphasizing the need for building design that considers energy performance to deal with climate problems. South Korea has constantly been tightening the design standards for saving building energy but with a focus on thermal performance and equipment systems. Accordingly, this study conducted an energy simulation experiment on office buildings with different window-to-wall ratios (WWRs) to propose a smart glazing plan to improve energy performance. An energy simulation experiment was performed on office buildings with varying WWRs to hierarchically analyze the influence of building window performance elements, including the heat transmission coefficient (U-value), visible light transmittance (VLT), and solar heat gain coefficient (SHGC), on building energy performance. The analysis showed that SHGC had the most significant impact on the heating and cooling load, by 22.13%, with the influences of the variables being 12.4% for the U-value, 4.78% for VLT, and 82.83% for SHGC. The results showed that the solar heat gain coefficient (SHGC) had the greatest impact on energy performance among window performance elements, and the effect increased significantly in certain WWRs. Moreover, to improve the energy performance of buildings with higher WWRs, it is essential to reflect the optimum composition of the U-value and SHGC on the window plan. This study's findings propose measures to supplement existing window plans focusing on thermal performance. Furthermore, these results hold academic value in providing concrete grounds for that. | Lee, Yu-Jeong; Kim, Sang-Hee; Ryu, Ji-Hye; Lee, Kweon-Hyoung | Dong Eui Univ, Div Urban Architecture & Civil Engn, Busan 47340, South Korea; Kyungpook Natl Univ, A3 Architectural Lab, Daegu 41566, South Korea; Kyungpook Natl Univ, Convergence Inst Construct Environm & Energy Engn, Daegu 41566, South Korea | Kim, Sang/D-3387-2011 | 58738917200; 57222484247; 56192651000; 56726955000 | leeujeong0@gamil.com;urban0039@naver.com;ryou0407@knu.ac.kr;idleekh@deu.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 13 | 11 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2023 | 3.1 | 27.7 | 0.29 | 2025-06-25 | 3 | 3 | building energy conservation; energy performance; building design; window-to-wall ratio; optical performance; glazing; SHGC; U-value; VLT | OPTIMIZATION; REGIONS | building design; building energy conservation; energy performance; glazing; optical performance; SHGC; U-value; VLT; window-to-wall ratio | Architectural design; Energy efficiency; Glazes; Historic preservation; Passive solar; Walls (structural partitions); Building design; Building energy conservation; Energy performance; Energy simulation; Glazing; Optical performance; Solar heat gain coefficient; U values; Visible light transmittances; Window-to-wall ratio; Office buildings | English | 2023 | 2023-11 | 10.3390/buildings13112850 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Quantitative Evaluation Method and Process of BIM Data for Generating BIM-Based 2D Deliverables | Views, drawings, and data extracted from building information modeling (BIM) constitute essential deliverables throughout the lifecycle of an architecture, engineering, and construction project, offering crucial insights for comprehending the design. Nevertheless, many employers evaluating BIM deliverables lack standardized criteria for the specific intended use of each BIM outcome, which hampers the practical utility of BIM results. This study introduces a quantitative evaluation method for the management of BIM-based two-dimensional (2D) deliverables. The BIM outcome measurement index for 2D deliverables (BOMI-2D) is formulated to provide a quantitative assessment of BIM data, focusing on their composition, structure, data readiness, and consistency. Pilot tests validated the efficacy of BOMI-2D, revealing an impressive 88.3% reduction in additional work required for 2D deliverables when data readiness increased by 25% and consistency improved by 32%. BOMI-2D is poised to play a pivotal role as an evaluation index for BIM data and outcomes, ultimately enhancing their utilization and productivity. | Kim, Yije; Chin, Sangyoon; Choo, Seungyeon | Sungkyunkwan Univ, Dept Convergence Engn Future City, Suwon 16419, South Korea; Sungkyunkwan Univ, Sch Civil Architectural Engn & Landscape Architect, Suwon 16419, South Korea; Kyungpook Natl Univ, Sch Architecture, Daegu 41566, South Korea | Choo, Seungyeon/JFB-0390-2023 | 57357791000; 7202600955; 36835366900 | yije89@gmail.com;schin@skku.edu;choo@knu.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 13 | 12 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2023 | 3.1 | 27.7 | 0.43 | 2025-06-25 | 3 | 3 | building information modeling (BIM); BIM outcome measurement; evaluation index; BIM-based drawings; 2D deliverables; readiness; consistency | MODEL | 2D deliverables; BIM outcome measurement; BIM-based drawings; building information modeling (BIM); consistency; evaluation index; readiness | Information theory; Life cycle; 2d deliverable; Building information modeling; Building information modeling outcome measurement; Building information modeling-based drawing; Building Information Modelling; Consistency; Evaluation index; Model-based OPC; Readiness; Architectural design | English | 2023 | 2023-12 | 10.3390/buildings13123124 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Designing attribute-based verifiable data storage and retrieval scheme in cloud computing environment | The cloud computing technology is a novel storage and computing paradigm that enables individuals and organizations to store data, share data with intended group of users and retrieve data when require. It greatly improves peoples' data storage and sharing, and data retrieval capabilities by providing flexible, less expensive and quality services. For data security and privacy concerns, secure and authenticated data storage, fine-grained access control of encrypted data, secure search for the outsourced data and search results verification are of critical importance. However, achieving the aforementioned functionalities simultaneously is quite challenging. In this paper, for the first time, we propose a secure lightweight Attribute-Based verifiable Data Storage and data Retrieval Scheme (ABDSRS) for cloud environments that attains the following features: (i) lightweight design, (ii) provably secure, (iii) fine-grained data access control, (iv) data owner (DO) anonymity, (v) data and DO authenticity, (vi) keyword policy search over encrypted data, (vii) keyword privacy, and (viii) search results verification. ABDSRS employs attribute-based online-offline mechanism in which only authorized DOs can anonymously upload data to the cloud. And, a data user (DU) can search over encrypted data using keyword policy. ABDSRS enables a DU to verify the correctness of the search results (i.e., the correctness of the operations performed by the cloud) without interacting with any authority. ABDSRS is lightweight in the sense that the heavy computations are offloaded either to the cloud or to offline phase, while only lightweight operations are executed at the DU device. We formalize more general security definitions of ABDSRS by considering various possible adversarial capabilities and present rigorous security analysis. We also conduct experiments to evaluate ABDSRS's performance. | Bera, Sourav; Prasad, Suryakant; Rao, Y.

| ○ | Article | Phase-controllable topochemical polymerization of liquid crystalline epoxy according to spacer length | Liquid crystalline epoxies (LCEs) have received considerable attention owing to their potential applications in heat dissipation in electronic devices. Herein, we report novel LCE systems (LCEn, n = spacer length) comprising bifunctional phenyl benzoate LC monomers with different spacers that are cured using an imidazole curing agent. Based on microstructural analyses, the lengths of the different alkyl chains considerably affect the LC phases. LCE4 and LCE6 exhibit smectic orientations, whereas LCE8 exhibits a nematic orientation during polymerization. All LCEn samples exhibit high thermal conductivities and superior thermal properties because the mesomorphic assemblies enhance their strong intra- and intermolecular interactions. LCE4, in particular, which displays a compact orientation order, exhibits remarkably high thermal conductivity (0.49 W m(-1) K-1). Furthermore, the LCEn samples exhibit superior thermal conductive behavior to those of existing commercial polymers. These results suggest the potential of LCEs as electronic materials based on their thermomechanical properties and high thermal conductivities. | Ku, Kyosun; Yeo, Hyeonuk | Kyungpook Natl Univ, Adv Inst Water Ind, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem Educ, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Pharm, Daegu 41566, South Korea | yeo, hyeonuk/G-7890-2017; Yeo, Hyeonuk/AHE-0397-2022 | yeo@knu.ac.kr; | POLYMER CHEMISTRY | POLYM CHEM-UK | 1759-9954 | 1759-9962 | 14 | 5 | SCIE | POLYMER SCIENCE | 2023 | 4.1 | 27.9 | 10 | HIGH THERMAL-CONDUCTIVITY; BORON-NITRIDE; RESIN; COMPOSITES; ELASTOMER; MORPHOLOGY; MECHANISM; ALIGNMENT; KINETICS; DRIVEN | English | 2023 | 2023-01-31 | 10.1039/d2py01454h | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Anti-Inflammatory and Antiatopic Effects of Rorippa cantoniensis (Lour.) Ohwi in RAW 264.7 and HaCaT Cells | This study evaluated the effects of Rorippa cantoniensis (Lour.) ohwi extract (RCE) on factors associated with inflammation-related skin lesions in RAW 264.7 and HaCaT cells. RCE inhibited the levels of proinflammatory mediators and cytokines such as nitric oxide (NO), prostaglandin E2 (PGE2), interleukin (IL)-6, and tumor necrosis factor (TNF)-α in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. In addition, RCE significantly inhibited the expression of chemokines and cytokines such as MDC/CCL22, TARC/CCL17, RANTES/CCL5, CTSS, IL-6, IL-1β, and TNF-α in HaCaT cells costimulated by TNF-α and interferon (IFN)-γ in a concentration-dependent manner. These results suggest that RCE attenuated the TNF-α- and IFN-γ-induced release of proinflammatory chemokines and cytokines probably by suppressing the activation of MAPK (JNK and p38), NF-κB, and STAT1 signaling. Moreover, RCE significantly increased the expression of skin components such as hyaluronic acid and aquaporin, which play important roles in the physical and chemical barriers of the skin. These results suggest that RCE has significant anti-inflammatory and antiatopic activities, which may be beneficial for the topical treatment of inflammatory skin disorders. © 2023 by the authors. | Kim, Min-Jin; Hwang, Buyng Su; Hwang, Yong; Jeong, Yong Tae; Jeong, Dae Won; Oh, Young Taek | Nakdonggang National Institute of Biological Resources, 137, Donam 2-gil, Sangju-si, 37242, South Korea, Department of Life Sciences, Kyungpook National University (KNU), 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Nakdonggang National Institute of Biological Resources, 137, Donam 2-gil, Sangju-si, 37242, South Korea; Nakdonggang National Institute of Biological Resources, 137, Donam 2-gil, Sangju-si, 37242, South Korea; Nakdonggang National Institute of Biological Resources, 137, Donam 2-gil, Sangju-si, 37242, South Korea; Nakdonggang National Institute of Biological Resources, 137, Donam 2-gil, Sangju-si, 37242, South Korea; Nakdonggang National Institute of Biological Resources, 137, Donam 2-gil, Sangju-si, 37242, South Korea | 58508828300; 35484054800; 57223012097; 57211430574; 58510314600; 56157403400 | alswls0428@nnibr.re.kr;ohyt@nnibr.re.kr; | Molecules | MOLECULES | N/A | 1420-3049 | 28 | 14 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 1.19 | 2025-06-25 | 8 | antiatopic activity; inflammatory; MAPK; NF-κB; Rorippa cantoniensis (Lour.)

| ○ | ○ | Article | Anti-Periodontitis Effects of Dendropanax morbiferus H.Lev Leaf Extract on Ligature-Induced Periodontitis in Rats | Periodontitis is caused by pathogens in the oral cavity. It is a chronic infectious disease that causes symptoms including gingival bleeding and tooth loss resulting from the destruction of periodontal tissues coupled with inflammation. Dendropanax morbiferus H.Lev (DM) is a natural product that exhibits various biological activities with few side effects. In this study, the potential of DM leaf hot-water extracts (DMWE) as a treatment for periodontitis was determined and its anti-oxidant and anti-inflammatory effects were evaluated. Compounds in DMWE were identified by high-performance liquid chromatography (HPLC) and nitric oxide (NO) and prostaglandin E-2 (PGE(2)) production was measured in RAW 264.7 cells. We measured the gingival index and gingival sulcus depth, and micro-CT was performed in vivo using a ligature-induced periodontitis rat model, which is similar to human periodontitis. The DMWE-treated group exhibited a decrease in cytokine concentration and relieved the gingival index and gingival sulcus depth compared with the periodontitis-induced control group. In addition, micro-CT and histological analysis revealed that DMWE exhibited anti-inflammatory effects and improved alveolar bone loss in periodontitis-induced rats. These findings suggest that DMWE has excellent anti-oxidant and anti-inflammatory effects that protect and prevent periodontal tissue damage and tooth loss caused by the inflammatory response. | Yang, Ye jin; Song, Jun-Ho; Yang, Ju-Hye; Kim, Min Jung; Kim, Kwang Youn; Kim, Jin-Kyoung; Jin, Yeung Bea; Kim, Woo Hyun; Kim, Suk; Kim, Ki-Rim; Park, Kwang Il; Lee, Hu-Jang | Gyeongsang Natl Univ, Coll Vet Med, Jinju 52828, South Korea; Korea Inst Oriental Med, Korean Med KM Applicat Ctr, Daegu 41062, South Korea; Daegu Hlth Coll, Dept Dent Hyg, Daegu 41453, South Korea; Kyungpook Natl Univ, Dept Dent Hyg, Sangju 37224, South Korea | ; Yang, Ju-Hye/GNH-6607-2022; Kim, Jinwoong/G-6289-2013; Song, Jun-Ho/AAA-2854-2021; Kim, Woo/A-8216-2019 | 58077409200; 58076580600; 57061012700; 57221073742; 58076309300; 57226774190; 59041371000; 55694027500; 26651495500; 35793746200; 55722171100; 7501491534 | rim0804@knu.ac.kr;kipark@gnu.ac.kr;hujang@gnu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 28 | 2 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 0.45 | 2025-06-25 | 2 | 3 | Dendropanax morbiferus H; Lev; periodontitis; anti-inflammation; anti-oxidant; alveolar bone; ligature-induced periodontitis | GINGIVAL CREVICULAR FLUID; PERI-IMPLANT DISEASES; CLASSIFICATION; ANTIOXIDANT; EXPRESSION; STRESS; CELLS; LPS | alveolar bone; anti-inflammation; anti-oxidant; Dendropanax morbiferus H.Lév; ligature-induced periodontitis; periodontitis | Alveolar Bone Loss; Animals; Anti-Inflammatory Agents; Antioxidants; Disease Models, Animal; Humans; Periodontitis; Plant Extracts; Rats; Tooth Loss; antiinflammatory agent; antioxidant; plant extract; alveolar bone loss; animal; complication; disease model; human; pathology; periodontal disease; periodontitis; rat | English | 2023 | 2023-01 | 10.3390/molecules28020849 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Chemical and Thermal Characteristics of Ion-Exchanged Lignosulfonate | Lignosulfonate features sulfonate groups, which makes it soluble in water and hence, suitable for a wide range of applications. However, its characterization is challenging because of its limited solubility in organic solvents. Thus, this study investigated the chemical and thermal characteristics of ion-exchanged sodium lignosulfonate (Na-LS) and compared it with those of industrial kraft lignin derived from softwood and hardwood. The results demonstrated that the ion exchange successfully converted Na-LS to lignosulfonic acid (H-LS), as proven by the Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and elemental analysis. H-LS has a greater apparent molecular weight than those of Na-LS and softwood and hardwood kraft lignin (SKL and HKL). According to P-31 nuclear magnetic resonance (NMR) analysis, H-LS has less phenolic OH than SKL and HKL, indicating that it has more polymeric chains. Furthermore, H-LS has substantially more native side chains, such as beta-O-4 units, than SKL and HKL. Thermal analysis revealed that H-LS has a greater glass temperature (T-g) than SKL and HKL, although Na-LS has a lower T-g than SKL and HKL. In addition, H-LS degraded faster than Na-LS did because the acid condition accelerated degradation reaction. | Wibowo, Eko Setio; Park, Byung-Dae | Kyungpook Natl Univ, Dept Wood & Paper Sci, Daegu 41566, South Korea; Natl Res & Innovat Agcy, Res Ctr Biomass & Bioprod, Bogor 16911, Indonesia | ; Park, Byung-Dae/ABB-1934-2020; Wibowo, Eko/AAL-5888-2021 | 57214910272; 7402834820 | byungdae@knu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 28 | 6 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 2.67 | 2025-06-25 | 17 | 20 | lignosulfonate; ion-exchange; kraft lignin; lignin structure; thermal properties | TECHNICAL LIGNINS; SODIUM LIGNOSULFONATE; ACID; CONVERSION; CATALYST; FRACTIONATION; SPECTROSCOPY; HYDROLYSIS | ion-exchange; kraft lignin; lignin structure; lignosulfonate; thermal properties | English | 2023 | 2023-03 | 10.3390/molecules28062755 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Microwave-Assisted Cu-Catalyzed Diaryletherification for Facile Synthesis of Bioactive Prenylated Diresorcinols | Prenylated diresorcinols exhibit various bioactivities, including cytotoxic, antibacterial, and antifungal activities. Therefore, establishing facile and efficient synthetic routes for prenylated diresorcinols facilitates their development as chemical probes or drugs with a novel mode of action. In this study, microwave-assisted copper catalysis was explored as a cost-effective and environmentally friendly method for the cross-coupling of sterically hindered ortho-prenylated phenols and aryl halides to produce bioactive prenylated diresorcinols, diorcinol I and leotiomycene B. Notable advantages of microwave-assisted catalysis include not only operational simplicity and rapid heating but also shorter reaction times and higher chemical yields. In addition, highly regioselective prenylation of phenol was achieved for the preparation of ortho-prenyl phenol via directed lithiation and subsequent alkylation. This study provides valuable insights for the preparation of other bioactive prenylated diresorcinols. Furthermore, considering that prenylated benzenoids are biosynthetic precursors of various polycyclic natural products, this synthetic route could be expanded to more complex bioactive compounds possessing diaryl ethers. | Jo, Seoyoung; Kang, Bohun; Jung, Jong-Wha | Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Coll Pharm, Daegu 41566, South Korea; Kyungpook Natl Univ, Vessel Organ Interact Res Ctr, Daegu 41566, South Korea | 57212269191; 57224409767; 26032128600 | jungj@knu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 28 | 1 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 0.3 | 2025-06-25 | 1 | 2 | Cu-catalyzed diaryletherification; microwave-assisted cross-coupling; prenylated diresorcinols; diorcinol I; leotiomycene B | DIPHENYL ETHERS; FUNGUS; MACROCYCLES; DERIVATIVES; CHEMISTRY; ARYLATION; PHENOLS; ROOTS | Cu-catalyzed diaryletherification; diorcinol I; leotiomycene B; microwave-assisted cross-coupling; prenylated diresorcinols | Catalysis; Ethers; Microwaves; Phenol; Phenols; ether derivative; phenol; phenol derivative; catalysis; chemistry; microwave radiation | English | 2023 | 2023-01 | 10.3390/molecules28010062 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Nature of Luminescence and Pharmacological Activity of Sulfaguanidine | Sulfonamides are one of the oldest groups of veterinary chemotherapeutic agents. Physico-chemical properties, the concentration and the nature of the environment are the factors responsible for the distribution of sulfonamides in the living organism. Although these drug compounds have been in use for more than half a century, knowledge about their behavior is still limited. Physiological activity is currently attributed to the sulfanyl radical. Our study is devoted to the spectral properties of aqueous solutions of sulfaguanidine, in which the formation of complexes with an H-bond and a protonated form takes place. The nature of the fluorescent state of sulfaguanidine was interpreted using computational chemistry, the electronic absorption method and the luminescence method. The structure of sulfaguanidine includes several active fragments: aniline, sulfonic and guanidine. To reveal the role of fragments in the physiological activity of the studied antibiotic, we calculated and compared the effective charges of the fragments of aniline and sulfaguanidine molecules. Chromophore groups were identified in molecules, which determine the intermolecular interaction between a molecule and a proton-donor solvent. The study also revealed the impact of sulfone and guanidine groups, as well as complexation, on the effective charge of the antibiotic fragment responsible for physiological activity and luminescent ability. | Tchaikovskaya, Olga; Bocharnikova, Elena; Bazyl, Olga; Chaidonova, Vlada; Mayer, George; Avramov, Paul | Russian Acad Sci, Inst Electrophys, Quantum Elect Lab, Ural Branch, Ekaterinburg 620146, Russia; Tomsk State Univ, Fac Phys, Lab Photophys & Photochem Mol, Tomsk 634050, Russia; Hyg & Epidemiol Ctr Republ Khakassia, Abakan 655017, Russia; Kyungpook Natl Univ, Dept Chem, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, 80 Daehak Ro, Daegu 41566, South Korea | Mayer, Georgiy/O-6690-2014; Bocharnikova, Elena/AAF-2312-2021; Tchaikovskaya, Olga/O-6715-2014 | 57997675500; 57208567909; 6602226139; 57214091375; 7201807576; 7004322420 | tchon@phys.tsu.ru;bocharnikova.2010@mail.ru;olga.k.bazyl@gmail.com;krayvlada0523@mail.ru;mayer_gv@mail.tsu.ru;paul.veniaminovich@knu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 28 | 10 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 0.74 | 2025-06-25 | 3 | 5 | sulfaguanidine; spectroscopy; H-bonded complexes; computational chemistry | DERIVATIVES | computational chemistry; H-bonded complexes; spectroscopy; sulfaguanidine | Aniline Compounds; Anti-Bacterial Agents; Guanidines; Luminescence; Sulfaguanidine; Sulfanilamide; Sulfonamides; aniline; aniline derivative; antiinfective agent; guanidine derivative; sulfaguanidine; sulfanilamide; sulfonamide; chemistry; luminescence | English | 2023 | 2023-05-18 | 10.3390/molecules28104159 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Reactive Disperse Dyes Bearing Various Blocked Isocyanate Groups for Digital Textile Printing Ink | Wastewater management is of considerable economic and environmental importance for the dyeing industry. Digital textile printing (DTP), which is based on sublimation transfer and does not generate wastewater, is currently being explored as an inkjet-based method of printing colorants onto fabric. It finds wide industrial applications with most poly(ethylene terephthalate) (PET) and nylon fibers. However, for additional industrial applications, it is necessary to use natural fibers, such as cotton. Therefore, to expand the applicability of DTP, it is essential to develop a novel reactive disperse dye that can interact with the fabric. In this study, we introduced a blocked isocyanate functional group into the dye to enhance binding to the fabric. The effect of sublimation transfer on fabrics as a function of temperature was compared using the newly synthesized reactive disperse dyes with different blocking groups based on pyrazole derivatives, such as pyrazole (Py), di-methylpyrazole (DMPy), and di-tert-butylpyrazole (DtBPy). Fabrics coated with the new reactive disperse dyes, including PET, nylon, and cotton, were printed at 190 degrees C, 200 degrees C, and 210 degrees C using thermal transfer equipment. In the case of the synthesized DHP-A dye on cotton at 210 degrees C, the color strength was 2.1, which was higher than that of commercial dyes and other synthesized dyes, such as DMP-A and DTP-A. The fastness values of the synthesized DHP-A were measured on cotton, and it was found that the washing and light fastness values on cotton are higher than those of commercial dyes. This study confirmed the possibility of introducing isocyanate groups into reactive disperse dyes. | Jeong, Subin; Kim, Giyoung; Bae, Hyoungeun; Kim, Hyeokjin; Seo, Eunjeong; Choi, Sujeong; Jeong, Jieun; Jung, Hyocheol; Lee, Sangho; Cheong, Inwoo; Kim, Jinchul; Park, Youngil | Korea Res Inst Chem Technol, Res Ctr Green Fine Chem, Ulsan 44412, South Korea; Korea Dyeing & Finishing Technol Inst, DYETEC Inst, Test Bed Res, Daegu 41706, South Korea; Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea | ; Kim, Kyoung-Sook/A-7768-2017; Lee, Sang-Ho/T-3699-2019 | 57683018600; 57210997221; 57578621900; 57189362981; 58094534200; 58246611000; 56330436800; 57015914900; 58743026900; 7006733373; 56805502600; 55494480300 | inwoo@knu.ac.kr;jckim81@krict.re.kr;ypark@krict.re.kr; | MOLECULES | MOLECULES | 1420-3049 | 28 | 9 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 0.45 | 2025-06-25 | 4 | 3 | digital textile printing; thermal transfer printing; reactive disperse dye; blocked isocyanate; anthraquinone dye | COTTON; NYLON; WATER | anthraquinone dye; blocked isocyanate; digital textile printing; reactive disperse dye; thermal transfer printing | English | 2023 | 2023-04-29 | 10.3390/molecules28093812 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Structural Analysis of Spermidine Synthase from Kluyveromyces lactis | Spermidine is a polyamine molecule that performs various cellular functions, such as DNA and RNA stabilization, autophagy modulation, and eIF5A formation, and is generated from putrescine by aminopropyltransferase spermidine synthase (SpdS). During synthesis, the aminopropyl moiety is donated from decarboxylated S-adenosylmethionine to form putrescine, with 5 '-deoxy-5 '-methylthioadenosine being produced as a byproduct. Although the molecular mechanism of SpdS function has been well-established, its structure-based evolutionary relationships remain to be fully understood. Moreover, only a few structural studies have been conducted on SpdS from fungal species. Here, we determined the crystal structure of an apo-form of SpdS from Kluyveromyces lactis (KlSpdS) at 1.9 angstrom resolution. Structural comparison with its homologs revealed a conformational change in the alpha 6 helix linked to the gate-keeping loop, with approximately 40 degrees outward rotation. This change caused the catalytic residue Asp170 to move outward, possibly due to the absence of a ligand in the active site. These findings improve our understanding of the structural diversity of SpdS and provide a missing link that expands our knowledge of the structural features of SpdS in fungal species. | Kim, Seongjin; Chang, Jeong Ho | Kyungpook Natl Univ, Dept Biol Educ, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Biomed Convergence Sci & Technol, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sci Educ Res Inst, 80 Daehak Ro, Daegu 41566, South Korea | 58220725700; 57203598905 | jhcbio@knu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 28 | 8 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 0.3 | 2025-06-25 | 2 | 2 | SpdS; spermidine; putrescine; polyamine; aminopropyltransferase | CRYSTAL-STRUCTURE; PLASMODIUM-FALCIPARUM; S-ADENOSYLMETHIONINE; POLYAMINE SYNTHESIS; INHIBITION; MECHANISM; BINDING | aminopropyltransferase; polyamine; putrescine; SpdS; spermidine | Kluyveromyces lactis; Polyamines; Putrescine; Spermidine; Spermidine Synthase; polyamine; putrescine; spermidine; spermidine synthase; chemistry; genetics; Kluyveromyces lactis | English | 2023 | 2023-04 | 10.3390/molecules28083446 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Structure and Vibrational Spectroscopy of C82 Fullerenol Valent Isomers: An Experimental and Theoretical Joint Study | Gd@C82OxHy endohedral complexes for advanced biomedical applications (computer tomography, cancer treatment, etc.) were synthesized using high-frequency arc plasma discharge through a mixture of graphite and Gd2O3 oxide. The Gd@C-82 endohedral complex was isolated by high-efficiency liquid chromatography and consequently oxidized with the formation of a family of Gd endohedral fullerenols with gross formula Gd@C82O8(OH)(20). Fourier-transformed infrared (FTIR) spectroscopy was used to study the structure and spectroscopic properties of the complexes in combination with the DFTB3 electronic structure calculations and infrared spectra simulations. It was shown that the main IR spectral features are formed by a fullerenole C-82 cage that allows one to consider the force constants at the DFTB3 level of theory without consideration of gadolinium endohedral ions inside the carbon cage. Based on the comparison of experimental FTIR and theoretical DFTB3 IR spectra, it was found that oxidation of the C-82 cage causes the formation of Gd@C82O28H20, with a breakdown of the integrity of the parent C-82 cage with the formation of pores between neighboring carbonyl and carboxyl groups. The Gd@C82O6(OOH)(2)(OH)(18) endohedral complex with epoxy, carbonyl and carboxyl groups was considered the most reliable fullerenole structural model. | Tomilin, Felix N.; Artyushenko, Polina V.; Shchugoreva, Irina A.; Rogova, Anastasia V.; Vnukova, Natalia G.; Churilov, Grigory N.; Shestakov, Nikolay P.; Tchaikovskaya, Olga N.; Ovchinnikov, Sergei G.; Avramov, Pavel V. | Fed Res Ctr KSC SB RAS, Kirensky Inst Phys, Krasnoyarsk 660036, Russia; Siberian Fed Univ, Sch Nonferrous Met & Mat Sci, Krasnoyarsk 660041, Russia; RAS, Fed Res Ctr Krasnoyarsk Sci Ctr, Lab Digital Controlled Drugs & Theranost, Siberian Branch, Krasnoyarsk 660036, Russia; VF Voino Yasenetsky Krasnoyarsk State Med Univ, Lab Biomol & Med Technol, Krasnoyarsk 660022, Russia; Tomsk State Univ, Dept Phys, Tomsk 634050, Russia; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea | Tomilin, Felix/F-3763-2014; Churilov, Grigory/A-3348-2014; Tchaikovskaya, Olga/AHA-4096-2022; Rogova, Anastasia/ADS-6671-2022; Artyushenko, Polina/AAO-8226-2020; Ovchinnikov, Sergei/GXF-4864-2022; Shestakov;, Nikolai/M-2163-2016 | 6602246772; 26429141000; 57206772345; 57214097579; 6603211758; 7004579568; 7005336539; 57997675500; 14122071800; 7004322420 | felixnt@gmail.com;paul.veniaminovich@knu.ac.kr; | MOLECULES | MOLECULES | 1420-3049 | 28 | 4 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 0.3 | 2025-06-25 | 3 | 2 | C-82; Gd endohedral complexes; biomedical applications; fullerenols; DFTB3 electronic structure calculations; IR spectra | C-60; METALLOFULLERENES; DERIVATIVES; RELAXIVITY; STABILITY; TRANSPORT; SPECTRA; DFT | biomedical applications; C<sub>82</sub>; DFTB3 electronic structure calculations; fullerenols; Gd endohedral complexes; IR spectra | Carbon; Fullerenes; Isomerism; Spectrum Analysis; carbon; fullerene derivative; fullerenol; chemistry; isomerism; spectroscopy | English | 2023 | 2023-02 | 10.3390/molecules28041569 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | The Use of Infrared Spectroscopy for the Quantification of Bioactive Compounds in Food: A Review | Infrared spectroscopy (wavelengths ranging from 750-25,000 nm) offers a rapid means of assessing the chemical composition of a wide range of sample types, both for qualitative and quantitative analyses. Its use in the food industry has increased significantly over the past five decades and it is now an accepted analytical technique for the routine analysis of certain analytes. Furthermore, it is commonly used for routine screening and quality control purposes in numerous industry settings, albeit not typically for the analysis of bioactive compounds. Using the Scopus database, a systematic search of literature of the five years between 2016 and 2020 identified 45 studies using near-infrared and 17 studies using mid-infrared spectroscopy for the quantification of bioactive compounds in food products. The most common bioactive compounds assessed were polyphenols, anthocyanins, carotenoids and ascorbic acid. Numerous factors affect the accuracy of the developed model, including the analyte class and concentration, matrix type, instrument geometry, wavelength selection and spectral processing/pre-processing methods. Additionally, only a few studies were validated on independently sourced samples. Nevertheless, the results demonstrate some promise of infrared spectroscopy for the rapid estimation of a wide range of bioactive compounds in food matrices. | Johnson, Joel B.; Walsh, Kerry B.; Naiker, Mani; Ameer, Kashif | Cent Queensland Univ, Sch Hlth Med & Appl Sci, North Rockhampton, Qld 4701, Australia; Univ Sargodha, Inst Food Sci & Nutr, Sargodha 40100, Pakistan; Chonnam Natl Univ, Dept Integrat Food Biosci & Biotechnol, Gwangju 61186, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | ; Johnson, Joel/AAA-1053-2020; Ameer, Kashif/H-5449-2019 | 57205101123; 7403291431; 23569829200; 57190066397 | joel.johnson@cqumail.com; | MOLECULES | MOLECULES | 1420-3049 | 28 | 7 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;CHEMISTRY, MULTIDISCIPLINARY | 2023 | 4.2 | 28.0 | 2.71 | 2025-06-25 | 40 | 48 | phenolics; bioactive compounds; infrared spectroscopy; NIR spectroscopy | TOTAL ANTIOXIDANT CAPACITY; QUEEN GARNET PLUM; PARTIAL LEAST-SQUARES; PROSPECTIVE COHORT; PHENOLIC-COMPOUNDS; MIDINFRARED SPECTROSCOPY; QUALITY ASSESSMENT; OLIVE OIL; REFLECTANCE SPECTROSCOPY; NIR SPECTROSCOPY | bioactive compounds; infrared spectroscopy; NIR spectroscopy; phenolics | Anthocyanins; Food; Polyphenols; Spectrophotometry, Infrared; Spectroscopy, Near-Infrared; anthocyanin; polyphenol; food; infrared spectrophotometry; near infrared spectroscopy; procedures | English | 2023 | 2023-04 | 10.3390/molecules28073215 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
