○ ○ Article ⓘ Red ginseng oil promotes hair growth and protects skin against UVC radiation ⓘ Background: A wide range of environmental factors, such as diseases, nutritional deficiencies, ageing, hormonal imbalances, stress, and ultraviolet (UV) radiation, may affect the structure and function of the skin that covers the entire surface of the human body. In this study, we investigated roles of red ginseng oil (RGO) in enhancing skin functions, including hair growth and skin protection, using mouse models. Methods: For hair growth experiment, shaved dorsal skins of C57BL/6 mice were topically applied with vehicle, RGO, RGO's major compounds, or minoxidil for consecutive 21 days and skin tissues were examined the hair growth promoting capacity. For skin protection experiment, SKH-1 hairless mice were topically applied with vehicle or RGO twice a day for three days prior to exposure to UVC radiation at 20 kJ/cm(2). Skin tissues were collected to evaluate skin protective effects of RGO. Results: Topical application of RGO to C57BL/6 mice effectively promoted hair regeneration by inducing early telogen-to-anagen transition and significantly increasing the density and bulb diameter of hair follicles. Major compounds, including linoleic acids and beta-sitosterol, contributed to RGO-promoted hair growth. Treatment with RGO as well as its major components upregulated expression of hair growth-related proteins. Furthermore, in SKH-1 hairless mice, RGO had a protective effect against UVC-induced skin damage by inhibiting inflammation and apoptosis, as well as inducing cytoprotective systems. Conclusion: These data suggest that RGO may be a potent agent for improving skin health and thereby preventing and/or treating hair loss and protecting skin against UV radiation.

○ ○ Article ⓘ The increasing hematopoietic effect of the combined treatment of Korean Red Ginseng and Colla corii asini on cyclophosphamide-induced immunosuppression in mice ⓘ Background: Hematopoiesis is the production of blood cells from hematopoietic stem cells (HSCs) that reside in the bone marrow. Cyclophosphamide (CTX) is a chemotherapy drug that suppresses the immune system. Korean Red Ginseng (KRG) and Colla corii asini (CCA) have been traditionally used for boosting the immune system. Methods: HSCs in the bone marrow, and immune cell subtype in splenocytes, PBMCs, and thymocytes were investigated. Serum levels of hematopoietic-related markers were analyzed using ELISA. Protein expression in spleen tissue was analyzed using western blot analysis. Hematoxylin & eosin staining in the femurs of mice were also conducted. Results: The combination of KRG and CCA with a ratio of 3:2 increased HSCs, CD3 and CD8(+) T cells in the circulation, and CD3 T cells in the spleen. A ratio of 2:3 (KRG:CCA) increased the thymic regulatory T cells and recovered the CD3 T cells in the spleen and circulation while recovering proteins in the JAK-STAT pathway in the spleen. Overall, blood cell population and differentiating factors vital for cell differentiation were also significantly recovered by all combinations especially in ratios of 3:2 and 2:3. Conclusion: A ratio of 3:2 (KRG:CCA) is the most ideal combination as it recovered the HSC population in the bone marrow of mice. (C) 2021 The Korean Society of Ginseng.

○ ○ Article ⓘ Eco-friendly and economically optimal design model (EEODM) to reduce the CO2 emissions and the cost of long-span waffle slabs ⓘ As the emission of CO2 is directly proportional to the nature of the materials used in the construction of buildings, an eco-friendly economic design is required for waffle slabs used in large buildings such as stores, shopping malls. In this study, a multi-objective optimization design model, denoted as an ecofriendly and economically optimal design model (EEODM), is proposed to reduce the CO2 emissions and costs of long-span waffle slabs. The developed model was analyzed to determine the change in CO2 emissions and costs with respect to design variables in 20 types of long-span waffle slabs. Based on the results of the analysis, CO2 emission efficiency analysis (CEEA) and cost-efficiency analysis (CEA) are proposed as the new qualitative scales to determine environmental and economic feasibility, respectively. Through CEEA and CEA, a new design standard is proposed to overcome the limitations of existing waffle forms. To verify the applicability of the EEODM, the model proposed in this study was applied to the actual waffle slab of Gimpo International Airport in Korea. The results indicate that the two proposed waffle forms reduced CO2 emissions and costs compared to the existing sections of the airport. (c) 2021 Elsevier Ltd. All rights reserved.

○ ○ Article ⓘ Effects of a transformative learning theory based debriefing in simulation: A randomized trial ⓘ Debriefing, based on reflection, is imperative in simulation. Mezirow's transformative learning theory (TLT) uses critical reflection in providing care to patients, which involves clinical judgment in nursing. The aim of this study was to compare the effects of TLT-versus a non-TLT-based debriefing protocol on knowledge, problem-solving process, critical thinking disposition, and clinical judgment in nursing students. A randomized controlled trial was performed. Fifty-six junior nursing students were assigned to the TLT (n = 26) and the control (n = 30) groups in South Korea. Debriefing protocols based on Mezirow's TLT for the experimental group and gatheranalyze-summarize-based debriefing for the control group were used for four weeks. Scores of the TLT group were significantly higher than those of the control group in the problem-solving process, critical thinking disposition, and clinical judgment of reflection. We identified the main effects of group, time, and time-by-group interaction for clinical judgment (noticing, interpreting, and responding), except for knowledge between the two groups. The TLT debriefing approach in simulation can be tailored to improve problem-solving, critical thinking, and clinical judgment outcomes, which are vital to nursing education related to the provision of care to patients. ⓘ Oh, Yun-Jeong; Kang, Hee-Young; Song, Yeoungsuk; Lindquist, Ruth ⓘ Nambu Univ, Dept Nursing, Gwangju, South Korea; Chosun Univ, Dept Nursing, Gwangju, South Korea; Kyungpook Natl Univ, Coll Nursing, 101 Dongin Dong, Daegu 700422, South Korea; Univ Minnesota, Sch Nursing, Minneapolis, MN 55455 USA ⓘ Song, Yeoungsuk/MSZ-3096-2025 ⓘ 57221313253; 36561677900; 55494171100; 35552932800 ⓘ 2000-tiger@hanmail.net;moohykang@naver.com;asansong@knu.ac.kr;lindq002@umn.edu; ⓘ NURSE EDUCATION IN PRACTICE ⓘ NURSE EDUC PRACT ⓘ 1471-5953 1873-5223 50 SCIE;SSCI NURSING ⓘ 2021 3.43 8.4 0.84 2025-07-30 ⓘ 11 8 Transformative learning theory; Knowledge; Problem-solving; Critical thinking; Clinical judgment ⓘ ⓘ Clinical judgment; Critical thinking; Knowledge; Problem-solving; Transformative learning theory ⓘ Clinical Competence; Education, Nursing; Humans; Judgment; Problem Solving; Problem-Based Learning; Republic of Korea; Students, Nursing; Thinking; adult; article; controlled study; critical thinking; decision making; female; group dynamics; human; learning theory; major clinical study; male; nursing education; nursing student; problem solving; randomized controlled trial; simulation; South Korea; clinical competence; decision making; nursing education; nursing student; problem based learning; problem solving; procedures; thinking ⓘ English 2021 2021-01 10.1016/j.nepr.2020.102962 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Understanding the impacts of the COVID-19 pandemic on sustainable agri-food system and agroecosystem decarbonization nexus: A review ⓘ The existing finite natural resources have witnessed unsustainable usage in the past few years, especially for food production, with accompanying environmental devastation and ecosystem damage. Regrettably, the global population and consumption demands are increasing ceaselessly, leading to the need for more resources for food production, which could potentially aggravate the sustainability and ecosystem degradation issues, while stimulating drastic climate change. Meanwhile, the unexpected emergence of the COVID-19 pandemic and some implemented measures to combat its spread disrupted agricultural activities and the food supply chain, which also led to a reduction in ecosystem carbonization. This study sets out to explore policy framework and selected feasible actions that are being adopted during the COVID-19 pandemic, which could potentially reduce the emissions even after the pandemic to promote a resilient and sustainable agri-food system. In this study, we reviewed 27 articles that focus on the current state of the agri-food system in light of the COVID-19 pandemic and its impact on the decarbonization of the agroecosystem. This review has taken the form of a systematic methodology in analyzing the adoption and implementation of various measures to mitigate the spread of COVID-19 on the impact of the agri-food system and reduction in ecosystem degradation. Up to 0.3 Mt of CO2 reduction from the agri-food system alone was reportedly achieved during the first 6 months of the pandemic in 23 European countries. The various adopted measures indicate that the circular economy approach is a panacea to achieve the needed sustainability in the agri-food system. Also, it dictates a need for a paradigm change towards improvement on localized food production that promotes sustainable production and consumption. ⓘ Adelodun, Bashir; Kareem, Kola Yusuff; Kumar, Pankaj; Kumar, Vinod; Choi, Kyung Sook; Yadav, Krishna Kumar; Yadav, Akanksha; El-Denglawey, A.; Cabral-Pinto, Marina; Son, Cao Truong; Krishnan, Santhana; Khan, Nadeem A. ⓘ Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Univ Ilorin, Dept Agr & Biosyst Engn, PMB 1515, Ilorin 240103, Nigeria; Gurukula Kangri Deemed Be Univ, Dept Zool & Environm Sci, Agroecol & Pollut Res Lab, Haridwar 249404, Uttarakhand, India; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu 41566, South Korea; Madhyanchal Profess Univ, Fac Sci & Technol, Ratibad, Bhopal 462044, India; Banaras Hindu Univ, Inst Sci, Dept Home Sci, MMV, Varanasi 221005, Uttar Pradesh, India; Taif Univ, Coll Univ Coll Turabah, Dept Phys, POB 11099, At Taif 21944, Saudi Arabia; Univ Aveiro, Dept Geosci, Geobiotec Res Ctr, P-3810193 Aveiro, Portugal; Vietnam Natl Univ Agr, Fac Nat Resources & Environm, Hanoi, Vietnam; Univ Teknol Malaysia UTM, Fac Engn, Sch Civil Engn, Ctr Environm Sustainabil & Water Secur IPASA,Res, Skudai 81310, Malaysia; Prince Songkla Univ, Fac Engn, Dept Environm Engn, PSU Energy Syst Res Inst, Hat Yai 90110, Songkhla, Thailand; Jamia Millia Islamia, Dept Civil Engn, New Delhi, India; South Valley Univ, Fac Sci, Dept Phys, Nano & Thin Film Lab, Qena 83523, Egypt ⓘ Kumar, P.Vinod/HKP-1552-2023; Adelodun, Bashir/O-2941-2018; Kumar, Pankaj/AAF-2231-2019; Krishnan, Santhana/Y-7862-2018; Kumar, Dr. Vinod/K-9971-2016; Krishnan, PhD, Santhana/Y-7862-2018; Yadav, Dr. Krishna Kumar/ABE-6962-2021; Khan, Nadeem/AAD-3306-2019; Pinto, Marina/AAA-6633-2022; Kareem, Kola/AAQ-8968-2021 ⓘ 57193774482; 57217253943; 57281192700; 57200152850; 54392662900; 57202908705; 57226434780; 57193526449; 22133337700; 57212762982; 56999772000; 57720323800 ⓘ adelodun.b@unilorin.edu.ng;ks.choi@knu.ac.kr;envirokrishna@gmail.com; ⓘ JOURNAL OF CLEANER PRODUCTION ⓘ J CLEAN PROD ⓘ 0959-6526 1879-1786 318 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY ⓘ 2021 11.072 8.4 2.91 2025-07-30 ⓘ 58 64 Sustainable agri-food system; COVID-19; Supply chain; Production and consumption; Circular economy ⓘ GREENHOUSE-GAS EMISSIONS; ENVIRONMENTAL IMPACTS; CIRCULAR ECONOMY; ECO-INNOVATION; CLIMATE-CHANGE; SUPPLY CHAIN; WASTE; MANAGEMENT; KNOWLEDGE; WATER ⓘ Circular economy; COVID-19; Production and consumption; Supply chain; Sustainable agri-food system ⓘ Carbonization; Climate change; Decarbonization; Ecosystems; Food supply; Supply chains; Sustainable development; % reductions; Agri-food system; Agro-ecosystems; Circular economy; Decarbonisation; Ecosystem degradation; Food production; Global population; Production and consumption; Sustainable agri-food system; COVID-19 ⓘ English 2021 2021-10-10 10.1016/j.jclepro.2021.128451 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Doping-induced photocatalytic activity and hydrogen evolution of ZnS: V nanoparticles ⓘ In the present study, we fabricate the ZnS: V (0, 2, 4, and 6 at%) nanoparticles (NPs) using the chemical-refluxing technique. We analyzed these samples based on structural, optical, magnetic, degradation, and hydrogen evolution properties. Comprehensive analyses of the chemical, structural, and optical measurements show that the vanadium (V) ions occupied the Zn host site without altering their original structure and without forming new phases. We confirmed the paramagnetic nature of the doped samples via magnetic measurements. We examined the photocatalytic properties of the fabricated NPs by the degrading Rhodamine-B (RhB) dye in an aqueous solution under the ultraviolet (UV) light, and the ZnS: V of 2 at% displayed higher degradation efficiency than the other samples. Moreover, 2 at% ZnS: V (sample showed a higher H2 evolution rate (1140 mu molg-1h-1) than the other samples and was 17 times greater than that of pure ZnS lattice. The observed efficient photocatalytic organic pollutant degradation and better hydrogen fuel evolution in 2 at% ZnS: V sample could be due to the presence of a large surface area, creation of more defect sites, dislocation sites of the prepared compound, generation, and the presence of a huge number of charge carriers due to the substitution of V-dopant in the Zn host site and non-recombination rate of charges. ⓘ Poornaprakash, B.; Park, Herie; Subramanyam, K.; Vattikuti, S.

○ ○ Article ⓘ Effective removal of Cr(VI) and methyl orange from the aqueous environment using two-dimensional (2D) Ti3C2Tx MXene nanosheets ⓘ Industrial use of heavy metals and dyes critically depends on the effective handling of industrial effluents. Effective remediation of industrial effluents using various adsorbent materials has thus become critical. In this paper, we study two-dimensional MXenes as an adsorbent for removing Cr(VI) and methyl orange (MO) in waters. The physico-chemical performance of MXenes was studied using X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller, scanning electron microscopy, high resolution-transmission electron microscopy, thermogravimetric analysis, and X-ray photoelectron spectroscopy techniques. The adsorption system, including influence of contact time, pH of solutions, co-ions, and desorption experiments were performed for effective Cr(VI) and MO removal. The Cr(VI) and MO removal rate of the MXenes was very fast, and the kinetic system was driven by pseudo-second-order kinetics. The sorption isotherm closely well-tailored with the Langmuir isotherm, and the maximum removal efficiencies were 104 and 94.8 mg/g for Cr (VI) and MO, respectively. The MXenes was successfully regenerated by 0.1 M NaOH aqueous solution and can be repeatedly recycled. The uptake of Cr(VI) and MO by the MXenes was mainly due to chemical adsorption, namely electrostatic adsorption, complexation, surface interactions, and ion exchange mechanisms. This investigation demonstrates the selectivity and feasibility of the MXenes as a real adsorbent for eliminating Cr(VI) and MO from the aqueous environment. ⓘ Karthikeyan, Perumal; Ramkumar, Krishnapillai; Pandi, Kalimuthu; Fayyaz, Aqsa; Meenakshi, Sankaran; Park, Chang Min ⓘ Deemed Univ Gandhigram, Gandhigram Rural Inst, Dept Chem, Dindigul 624302, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Inst Sci & Technol KIST, Ctr Environm Hlth & Welf Res, Hwarang Ro 14, Seoul 02792, South Korea ⓘ Kalimuthu, Pandi/AAV-6987-2021; Karthikeyan, Perumal/T-6719-2019; Meenakshi, Sankaran/AAF-5748-2020; Park, Chang Min/CAA-8506-2022 ⓘ 57207499412; 57218685433; 56273058900; 57217157699; 58099005900; 57209588953 ⓘ karthi2011chemistry@gmail.com;ramkumar007ckpt@gmail.com;kpandi@kist.re.kr;aqsafayyaz10@gmail.com;sankaranmeenakshi2014@gmail.com;cmpark@knu.ac.kr; ⓘ CERAMICS INTERNATIONAL ⓘ CERAM INT ⓘ 0272-8842 1873-3956 47 3 SCIE MATERIALS SCIENCE, CERAMICS ⓘ 2021 5.532 8.6 7.57 2025-07-30 ⓘ 116 131 MXenes; Adsorption; Isotherm; Hexavalent chromium; Methyl orange ⓘ EFFICIENT REMOVAL; ADSORPTION; PHOSPHATE; COMPOSITE; PERFORMANCE; CHROMIUM; CHITOSAN; DYE; VI ⓘ Adsorption; Hexavalent chromium; Isotherm; Methyl orange; MXenes ⓘ Adsorption; Adsorption isotherms; Azo dyes; Chemical analysis; Citrus fruits; Effluents; Fourier transform infrared spectroscopy; Heavy metals; High resolution transmission electron microscopy; Ion exchange; Scanning electron microscopy; Sewage; Sodium hydroxide; Thermogravimetric analysis; X ray photoelectron spectroscopy; Chemical adsorption; Electrostatic adsorption; Industrial effluent; Ion exchange mechanisms; Pseudo second order kinetics; Removal efficiencies; Surface interactions; Two Dimensional (2 D); Chromium compounds ⓘ English 2021 2021-02-01 10.1016/j.ceramint.2020.09.221 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Energy transfer and luminescence study of Dy3+doped zinc-aluminoborosilicate glasses for white light emission ⓘ A series of Dy3+ doped aluminoborosilicate glasses with general formula 20SiO(2)-(40-x)B2O3-10Al(2)O(3)-20NaF(2)-10ZnO-xDy(2)O(3) (x = 0, 0.1, 0.5, 1.0. 1.5, 2.0 and 2.5 mol %) were prepared by melt-quenching method. The FTIR analysis confirms the presence of stretching and bending vibrations of BO4, BO3 and SiO4 units in the prepared glasses. DTA results show that Tg is decreasing with addition of Dy3+ ions in the glass system. Theoretically calculated mechanical properties such as elastic modulus, bulk modulus, shear modulus and Poisson's ratio suggest the increase in mechanical stability of glasses with dysprosium addition. Also experimental analysis carried out using Vicker's microhardness suggests glass stability with applied loads. Absorption spectrum shows twelve bands that exist due to transition from H-6(15/2) level to different excited levels. Nephelauxetic ratio and bonding parameter calculated shows decreasing ionicity of glasses with increase in Dy3+ ions. Judd-Oflet parameter calculated for all the glasses follow the trend 526 > 524 > 524. Luminescence study shows three emission peaks having transitions from F-4(9/2) -> H-6(15/2) (blue), F-4(9/2) -> H-6(13/2) (yellow) and F-4(9/2) -> H-6(11/2) (red). Radiative parameters calculated suggest higher stimulated emission cross-section for present glasses having F-4(9/2) -> H-6(13/2) transition. The decay measurement for all the glass samples were recorded with an excitation at 350 nm and monitoring emission at 575 nm corresponding to the F-4(9/2) -> H-6(13/2) transition and decay curves were fitted to bi-exponential fit. The CIE colour chromaticity coordinates were determined using CIE chromaticity diagram and the values were found to be in close proximity with the standard white light (0.33. 0.33) for all the glasses.

○ ○ Article ⓘ Magnetic, electron paramagnetic resonance, and photocatalytic analysis of diluted magnetic semiconductor CdS:V nanoparticles ⓘ Diluted magnetic semiconductors related to II?VI-based compounds are of significant interest for the development of spin-based operating electronic devices such as magneto-optical instruments, spintronics, and nonvolatile memory devices. Thus, studies of electron paramagnetic resonance, magnetic characteristics, and the photocatalytic properties of transition metal-doped II-VI-based semiconductors are of great importance. We therefore comprehensively studied the structural, electron spin resonance, magnetic hysteresis, and photocatalytic characteristics of CdS:V4+ nanoparticles (NPs) fabricated by the rapid microwave route for the first time. The structural analyses revealed the authentic substitution of V4+ dopant ions into the CdS matrix. The widening of the optical band gap and relevant quantum confinement phenomenon are discussed in terms of the inclusion of V4+ ions into the CdS matrix. The electron paramagnetic resonance (EPR) spectroscopy results were corroborated by the increase in the number of magnetic spins with increasing V4+ dopant concentration. The assessed number of magnetic spins was nearly equal to 3.601597 x 10(6) and 7.254048 x 10(6) for the CdS:V (2 and 4 at%) NPs, respectively. Room-temperature magnetic hysteresis loops also revealed the existence of a large number of magnetic spins through the formation of clear paramagnetism in the CdS:V (2 and 4 at%) NPs. The CdS:V (4 at%) system displayed enriched visible light-driven photocatalytic degradation efficiency compared to bare CdS through the degradation of RhB dye in contaminated water. ⓘ Poornaprakash, B.; Vattikuti, S.

○ ○ Article ⓘ Photoluminescence and hydrogen evolution properties of ZnS:Eu quantum dots ⓘ In the era of Photonics, design and development of novel rare earth ion-doped quantum dots (QDs) for optoelectronic applications has gained significant interest owing to their outstanding characteristics. Simultaneously, the creation of a new class of photocatalytic materials on the nanoscale is also imperative for environmental purification. Thus, we report on wet chemical synthesis, the structural, morphological, and optical characteristics, fluorescence, and hydrogen evolution of ZnS:Eu (0, 2, 4, and 6 at%) QDs for optoelectronic and photocatalytic applications. Comprehensive structural studies depicted that Eu3+ ions were efficiently substituted into the host matrix and altered the original structure of the ZnS compound. The emission spectra of the ZnS:Eu QDs exhibited distinctive red fluorescence owing to the transition of dopant ions in 5D0 - 7F1, 5D0 - 7F2, 5D0 - 7F3, and 5D0 - 7F4 energy levels of the 4f orbital of the Eu3+ ions. Moreover, the photocatalytic properties of ZnS:Eu (6 at %) QDs possess better catalytic efficiency toward hydrogen evolution through a water splitting mechanism under simulated sunlight irradiation. The observed photocatalytic phenomenon in the synthesized samples agreed well with the luminescence properties exhibited by the QDs. ⓘ Poornaprakash, B.; Vattikuti, S. V.

○ ○ Article ⓘ Robust ferromagnetism of ZnO:(Ni plus Er) diluted magnetic semiconductor nanoparticles for spintronic applications ⓘ The design and production of co-doped diluted magnetic semiconductor nanostructures for the development of spin-related operating electronic devices have gained considerable attention owing to their formidable characteristics. In this study, we strived to fabricate ZnO, Zn0.98Ni0.02O, Zn0.97Ni0.02Er0.01O, and Zn0.96Ni0.02Er0.02O nanoparticles. The successful penetration of Ni and Er ions into the ZnO host material was confirmed through wide-ranging structural analyses. A slight change in the bandgap of ZnO was obtained by doping and co-doping. The photoluminescence spectra revealed that doping and co-doping induced various emissions as well as structural defects in the fabricated nanoparticles. Magnetic hysteresis loops revealed that the ZnO and Zn0.98Ni0.02O nanoparticles possessed a paramagnetic nature. However, the Zn0.97Ni0.02Er0.01O and Zn0.96Ni0.02Er0.02O nanoparticles exhibited robust ferromagnetism with clear hysteresis loops. Bound magnetic polaron behavior is well-anticipated to describe the ferromagnetism in the synthesized nanoparticles. Hence, (Ni + Er) co-doping is a promising approach for extending the ferromagnetic nature of the ZnO system for spin-based electronic devices. ⓘ Poornaprakash, B.; Ramu, S.; Subramanyam, K.; Kim, Y.

○ ○ Article ⓘ Role of oxygen vacancy defects in piezoelectric thermal stability characteristics of Mn-doped (K,Na,Li)NbO3 piezoceramics ⓘ Piezoelectric thermal stability characteristics of (K,Na,Li)NbO3 ceramics were investigated with a particular focus on the role of oxygen vacancy defects, by excluding the lattice distortion or microstructural effects with the help of a low level of Mn doping (less than 1.0 mol%). Benefiting from the reduction of intrinsic oxygen vacancy defects, controlled Mn doping (0.25 mol%) could achieve excellent ferroelectric/piezoelectric activity and superior thermal aging resistance. Beyond this doping level, however, the defect dipoles combined with extrinsic oxygen vacancies, although advantageous to the hardening effect, deteriorated the piezoelectric thermal stability and aging resistance including room-temperature properties. The thermal dissociation and migration of oxygen vacancy-associated defect dipoles were considered mainly responsible for negating the ability to restore the initial poled domain state with defect-dipole-induced polarization. Results demonstrated the importance of keeping the intrinsic and extrinsic oxygen vacancy levels as low as possible for lead-free (K,Na)NbO3 systems with more thermally stable domain structure. ⓘ Ma, Hee-Seung; Lee, Min-Ku; Kim, Byung-Hoon; Park, Kyu-Hyun; Park, Jin-Ju; Lee, Sang-Hyeop; Jeong, Yun-Gi; Kwi-Il Park; Jeong, Chang Kyu; Lee, Gyoung-Ja ⓘ Korea Atom Energy Res Inst, Smart Struct Safety & Prognosis Res Div, 111 Daedeok Daero,989 Beon Gil, Daejeon 34057, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Jeonbuk Natl Univ, Div Adv Mat Engn, 567 Baekje Daero, Jeonju 54896, Jeonbuk, South Korea ⓘ Jeong, Chang Kyu/ADT-8127-2022; Park, Kwiil/LKN-9445-2024 ⓘ 57225944898; 59302175900; 57205869559; 57210371510; 24399310900; 57225978780; 57225931077; 35280874200; 55961876600; 8588965200 ⓘ leegj@kaeri.re.kr; ⓘ CERAMICS INTERNATIONAL ⓘ CERAM INT ⓘ 0272-8842 1873-3956 47 19 SCIE MATERIALS SCIENCE, CERAMICS ⓘ 2021 5.532 8.6 1.79 2025-07-30 ⓘ 36 34 Lead-free piezoelectrics; (K,Na)NbO3-Based ceramics; Oxygen vacancy defects; Doping; Manganese ⓘ LEAD-FREE PIEZOCERAMICS; ELECTRICAL-PROPERTIES; FERROELECTRIC PROPERTIES; GIANT PIEZOELECTRICITY; DIELECTRIC-RELAXATION; TEMPERATURE STABILITY; MANGANESE ADDITION; CERAMICS; LI; MICROSTRUCTURE ⓘ (K,Na)NbO<sub>3</sub>-Based ceramics; Doping; Lead-free piezoelectrics; Manganese; Oxygen vacancy defects ⓘ Doping (additives); Niobium compounds; Oxygen vacancies; Piezoelectric ceramics; Thermal aging; Thermodynamic stability; (K,na)NbO3-based ceramic; Ageing resistance; Defect dipoles; Lead-free piezoelectrics; Li$++$; Mn-doping; Oxygen vacancy defects; Piezoelectric; Thermal; Thermal stability characteristics; Piezoelectricity ⓘ English 2021 2021-10-01 10.1016/j.ceramint.2021.06.207 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Synthesis of 3D nanoflower-like mesoporous NiCo2O4 N-doped CNTs nanocomposite for solid-state hybrid supercapacitor; efficient material for the positive electrode ⓘ In this research work, we report a novel method for developing ternary NiCo2O4 compounds using deep eutectic solvents (DESs) and a strategy for improving their pseudocapacitive performance. NiCo2O4 composites with Ndoped carbon nanotubes (NCNTs) were fabricated on Ni foam using a hydrothermal method. The electrochemical performance of the NiCo2O4 was altered with the change in the reaction temperature. The composite of NiCo2O4 and NCNTs demonstrated a maximum value of specific capacity of 303 mAh g-1 at a scan rate of 5 mV s-1. The specific capacity for the composite compound was 1.3-fold greater than that of the pristine NiCo2O4 sample. For practical applications, we constructed a flexible solid-state hybrid supercapacitor comprised of NiCo2O4/ NCNTs//activated carbon (AC) cells with an excellent energy density of 12.31 Wh kg- 1, outstanding power density of 8.96 kW kg- 1, and tremendous electrode stability. The three-dimensional mesoporous nanoflowers and nanotubes-like nanostructures of NiCo2O4 are well-suited for use in hybrid devices as well as convenient for flexible electronic devices. ⓘ Shinde, Surendra K.; Karade, Swapnil S.; Maile, Nagesh C.; Yadav, Hemraj M.; Ghodake, Gajanan S.; Jagadale, Ajay D.; Jalak, Monali B.; Lee, Dae Sung; Kim, Dae-Young ⓘ Dongguk Univ, Dept Biol & Environm Sci, Coll Life Sci & Biotechnol, Biomed Campus,32 Dongguk ro, Goyang Si, Gyeonggi Do, South Korea; Yonsei Univ, Dept Chem & Biomol Engn, Electrochem Energy Lab, Seoul, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; SASTRA Deemed Univ, Sch Elect & Elect Engn, Ctr Energy Storage & Convers, Thanjavur 613401, Tamil Nadu, India; Shivaji Univ, Dept Phys, Kolhapur, Maharashtra, India ⓘ Jagadale, Ajay/O-5253-2014; Shinde, Santaji/LFT-9528-2024; Karade, Swapnil/AAA-8285-2020; Maile, Nagesh/AFD-8838-2022 ⓘ 55776351000; 56674484600; 57193804539; 55389590800; 22979024500; 44161199800; 57203877390; 55568524907; 55742887400 ⓘ sbpkim@dongguk.edu; ⓘ CERAMICS INTERNATIONAL ⓘ CERAM INT ⓘ 0272-8842 1873-3956 47 22 SCIE MATERIALS SCIENCE, CERAMICS ⓘ 2021 5.532 8.6 1.51 2025-07-30 ⓘ 24 25 NiCo2O4; NCNTs; Composite; Deep eutectic solvents; Hydrothermal method; Hybrid supercapacitor ⓘ THIN-FILMS; ELECTROCHEMICAL PERFORMANCE; 3-DIMENSIONAL GRAPHENE; HYDROTHERMAL SYNTHESIS; CHEMICAL-SYNTHESIS; POROUS NICO2O4; CARBON; OXYGEN; ELECTROCATALYST; NANOSHEETS ⓘ Composite; Deep eutectic solvents; Hybrid supercapacitor; Hydrothermal method; NCNTs; NiCo<sub>2</sub>O<sub>4</sub> ⓘ Doping (additives); Electrodes; Eutectics; Foams; Hydrothermal synthesis; Nanoflowers; Nickel compounds; Supercapacitor; Deep eutectic solvents; Doped carbons; Hybrid supercapacitors; Hydrothermal methods; Mesoporous; N-doped; N-doped carbon nanotube; Novel methods; Positive electrodes; Specific capacities; Carbon nanotubes ⓘ English 2021 2021-11-15 10.1016/j.ceramint.2021.08.045 ⓘ 바로가기 바로가기 바로가기 바로가기
