| ○ | ○ | Article | Improvement of the Uniformity and Electrical Properties of Polyaniline Nanocomposite Film by Addition of Auxiliary Gases during Atmospheric Pressure Plasma Polymerization | The morphological and chemical properties of polyaniline (PANI) nanocomposite films after adding small amounts of auxiliary gases such as argon, nitrogen, and oxygen during atmospheric pressure (AP) plasma polymerization are investigated in detail. A separate gas-supply line for applying an auxiliary gas is added to the AP plasma polymerization system to avoid plasma instability due to the addition of auxiliary gas during polymerization. A small amount of neutral gas species in the plasma medium can reduce the reactivity of monomers hyperactivated by high plasma energy and prevent excessive crosslinking, thereby obtaining a uniform and regular PANI nanocomposite film. The addition of small amounts of argon or nitrogen during polymerization significantly improves the uniformity and regularity of PANI nanocomposite films, whereas the addition of oxygen weakens them. In particular, the PANI film synthesized by adding a small amount of nitrogen has the best initial electrical resistance and resistance changing behavior with time after the ex situ iodine (I-2)-doping process compared with other auxiliary gases. In addition, it is experimentally demonstrated that the electrical conductivity of the ex situ I-2-doped PANI film can be preserved for a long time by isolating it from the atmosphere. | Kim, Jae-Young; Jang, Hyo-Jun; Jung, Eunyoung; Bae, Gyutae; Lee, Soonwon; Park, Choon-Sang; Shin, Bhumjae; Tae, Heung-Sik | Kyungpook Natl Univ, Sch Elect & Elect Engn, Coll IT Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Coll IT Engn, Daegu 41566, South Korea; Kansas State Univ, Dept Elect & Comp Engn, Coll Engn, Manhattan, KS 66506 USA; Sejong Univ, Dept Elect Engn, Seoul 05006, South Korea | ; Shin, BhumJae/AEV-2572-2022 | 57205191453; 57207956623; 57203199724; 57202369078; 57247086400; 16025295400; 7103027782; 7006298844 | jyk@knu.ac.kr;bs00201@knu.ac.kr;eyjung@knu.ac.kr;doctor047@knu.ac.kr;impulsive1@naver.com;purplepcs@ksu.edu;hahusbj@sejong.ac.kr;hstae@ee.knu.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.38 | 2025-07-30 | 9 | 9 | atmospheric pressure plasma polymerization; auxiliary gas addition; conductive polymer film; conjugated polymer film; plasma polymerization; polyaniline nanocomposites | CONDUCTING POLYMER; DEPOSITION; COMPOSITES; MULTILAYER; THIOPHENE; PYRROLE; DEVICES; REMOTE; DOPANT; RF | Atmospheric pressure plasma polymerization; Auxiliary gas addition; Conductive polymer film; Conjugated polymer film; Plasma polymerization; Polyaniline nanocomposites | English | 2021 | 2021-09 | 10.3390/nano11092315 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Microwave-Assisted Synthesis of Ge/GeO2-Reduced Graphene Oxide Nanocomposite with Enhanced Discharge Capacity for Lithium-Ion Batteries | Germanium/germanium oxide nanoparticles with theoretically high discharge capacities of 1624 and 2152 mAh/g have attracted significant research interest for their potential application as anode materials in Li-ion batteries. However, these materials exhibit poor long-term performance due to the large volume change of 370% during charge/discharge cycles. In the present study, to overcome this shortcoming, a Ge/GeO2/graphene composite material was synthesized. Ge/GeO2 nanoparticles were trapped between matrices of graphene nanosheets to offset the volume expansion effect. Transmission electron microscopy images revealed that the Ge/GeO2 nanoparticles were distributed on the graphene nanosheets. Discharge/charge experiments were performed to evaluate the Li storage properties of the samples. The discharge capacity of the bare Ge/GeO2 nanoparticles in the first discharge cycle was considerably large; however, the value decreased rapidly with successive cycles. Conversely, the present Ge/GeO2/graphene composite exhibited superior cycling stability. | Koo, Ji-Hye; Paek, Seung-Min | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea | Paek, Seung-Min/E-4667-2011 | 57221701800; 7102686289 | guzza95@naver.com;smpaek@knu.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 1.33 | 2025-07-30 | 28 | 28 | germanium oxide; graphene composite; anode material; lithium-ion battery | Anode material; Germanium oxide; Graphene composite; Lithium-ion battery | English | 2021 | 2021-02 | 10.3390/nano11020319 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Modulation of Conductivity and Contact Resistance of RuO2 Nanosheets via Metal Nano-Particles Surface Decoration | We studied the variation in electrical conductivity of exfoliated RuO2 nanosheets and the modulation in the contact resistance of individual nanosheet devices using charge transfer doping effects based on surface metal nanoparticle decorations. The electrical conductivity in the monolayer and bilayer RuO2 nanosheets gradually increased due to the surface decoration of Cu, and subsequently Ag, nanoparticles. We obtained contact resistances between the nanosheet and electrodes using the four-point and two-point probe techniques. Moreover, the contact resistances decreased during the surface decoration processes. We established that the surface decoration of metal nanoparticles is a suitable method for external contact engineering and the modulation of the internal properties of nanomaterials. | Kim, Jongwon; Youn, Seonhye; Baek, Ju Young; Kim, Dong Hwan; Kim, Sumin; Lee, Wooyoung; Park, Hee Jung; Kim, Juyoung; Chun, Dong Won; Park, Sang-Shik; Roh, Jong Wook; Kim, Jeongmin | DGIST, Div Nanotechnol, 333 Techno Jungang Daero, Daegu 42988, South Korea; Kyungpook Natl Univ, Sch Nano Mat Engn, Sangju 37224, South Korea; Yonsei Univ, Dept Mat Sci & Engn, 50 Yonsei Ro, Seoul 03722, South Korea; Dankook Univ, Dept Mat Sci & Engn, 119 Dandae Ro, Cheonan 31116, South Korea; Korea Inst Sci & Technol, Ctr Energy Mat Res, Seoul 02792, South Korea | ; Kim, Sumin/AAI-1978-2020 | 57234817500; 57218557480; 57188711669; 57195540717; 57898467900; 55498383000; 7601568847; 57201935243; 15047830500; 7501833211; 25638796100; 57203325094 | jwkp9605@knu.ac.kr;seonhye0718@yonsei.ac.kr;jooyeong@dgist.ac.kr;Kimdhwan@dgist.ac.kr;suminkim@yonsei.ac.kr;wooyoung@yonsei.ac.kr;parkjang@dankook.ac.kr;jykim1299@kist.re.kr;chundream98@kist.re.kr;parkss@knu.ac.kr;jw.roh@knu.ac.kr;jkim@dgist.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.25 | 2025-07-30 | 3 | 4 | two-dimensional materials; RuO2; nanosheets; surface charge transfer; electrical conductivity; contact resistance | MOS2; LAYER; GAS | Contact resistance; Electrical conduc-tivity; Nanosheets; RuO2; Surface charge transfer; Two-dimensional materials | English | 2021 | 2021-09 | 10.3390/nano11092444 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Nano/Micro-Structured ZnO Rods Synthesized by Thermal Chemical Vapor Deposition with Perpendicular Configuration | Under a one-step process, catalyst-free growth of one-dimensional (1D) ZnO hierarchical nanostructures was performed on ZnO-seeded Si substrate by thermal chemical vapor deposition with a perpendicular setup. The morphological and crystallographic properties of the nano/micro-structured ZnO rods were investigated with varying growth temperature and growth time. X-ray diffraction patterns of 1D ZnO double-structured rods showed the hexagonal wurtzite structure. The morphology and crystal structure of the ZnO double-structured rods were sensitive to the growth temperature and growth time. From Raman scattering and photoluminescence spectra, the orientation and size effects of the ZnO double-structured rods were discussed in relation to growth temperatures and growth times. | Choi, Seok Cheol; Lee, Do Kyung; Sohn, Sang Ho | LG Elect, Dept Proc Dev, Gumi 39368, South Korea; Daegu Catholic Univ, Sch Adv Mat Sci & Chem Engn, Gyongsan 38430, South Korea; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea | 59102851900; 55941000700; 7101646506 | jomi119@hanmail.net;dokyung@cu.ac.kr;shsohn@knu.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 10 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.38 | 2025-07-30 | 6 | 7 | one-dimensional ZnO hierarchical nanostructures; nano/micro-structured ZnO rods; ZnO double-structured rods; thermal chemical vapor deposition; perpendicular configuration; one-step process | ZINC-OXIDE; PHOTOLUMINESCENCE; GROWTH; NANOSTRUCTURES; TEMPERATURE; NANOFLOWERS | Nano/micro-structured ZnO rods; One-dimensional ZnO hierarchical nanostructures; One-step process; Perpendicular configuration; Thermal chemical vapor deposition; ZnO double-structured rods | English | 2021 | 2021-10 | 10.3390/nano11102518 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Polyethylene Glycol Coated Magnetic Nanoparticles: Hybrid Nanofluid Formulation, Properties and Drug Delivery Prospects | Magnetic nanoparticles (MNPs) are widely used materials for biomedical applications owing to their intriguing chemical, biological and magnetic properties. The evolution of MNP based biomedical applications (such as hyperthermia treatment and drug delivery) could be advanced using magnetic nanofluids (MNFs) designed with a biocompatible surface coating strategy. This study presents the first report on the drug loading/release capability of MNF formulated with methoxy polyethylene glycol (referred to as PEG) coated MNP in aqueous (phosphate buffer) fluid. We have selected MNPs (NiFe(2)O4, CoFe(2)O4 and Fe3O4) coated with PEG for MNF formulation and evaluated the loading/release efficacy of doxorubicin (DOX), an anticancer drug. We have presented in detail the drug loading capacity and the time-dependent cumulative drug release of DOX from PEG-coated MNPs based MNFs. Specifically, we have selected three different MNPs (NiFe2O4, CoFe2O4 and Fe3O4) coated with PEG for the MNFs and compared their variance in the loading/release efficacy of DOX, through experimental results fitting into mathematical models. DOX loading takes the order in the MNFs as CoFe2O4 > NiFe2O4 > Fe3O4. Various drug release models were suggested and evaluated for the individual MNP based NFs. While the non-Fickian diffusion (anomalous) model fits for DOX release from PEG coated CoFe2O4, PEG coated NiFe2O4 NF follows zero-order kinetics with a slow drug release rate of 1.33% of DOX per minute. On the other hand, PEG coated NiFe2O4 follows zero-order DOX release. Besides, several thermophysical properties and magnetic susceptibility of the MNFs of different concentrations have been studied by dispersing the MNPs (NiFe2O4, CoFe2O4 and Fe3O4) in the base fluid at 300 K under ultrasonication. This report on the DOX loading/release capability of MNF will set a new paradigm in view that MNF can resolve problems related to the self-heating of drug carriers during mild laser treatment with its thermal conducting properties. | Mannu, Rashmi; Karthikeyan, Vaithinathan; Velu, Nandakumar; Arumugam, Chandravadhana; Roy, Vellaisamy A.

| ○ | ○ | Article | Porous Hybrids Structure between Silver Nanoparticle and Layered Double Hydroxide for Surface-Enhanced Raman Spectroscopy | Silver nanoparticle (AgNP), in terms of antibacterial, catalytic, electronic, and optical applications, is an attractive material. Especially, when prepared to furnish sharp edge and systematic particle orientation on the substrate, AgNPs can take advantage of surface-enhanced Raman spectroscopy (SERS). In this research, we suggested a synthetic method to immobilize the AgNP on metal oxide by utilizing Ag-thiolate and layered double hydroxide (LDH) as precursor and template, respectively. The layer-by-layer structure of LDH and Ag-thiolate transformed through reductive calcination to metal oxide and AgNP array. Physicochemical characterization, including powder X-ray diffraction, N2 adsorption-desorption, microscopies, and X-ray photoelectron spectroscopy, revealed that the AgNP with sufficient crystallinity and particle gap was obtained at relatively high calcination temperature, similar to 600 degrees C. UV-vis diffusion reflectance spectroscopy showed that the calcination temperature affected particle size and electronic structure of AgNP. The prepared materials were subjected to SERS tests toward 4-nitrothiophenol (4-NTP). The sample obtained at 600 degrees C exhibited 50 times higher substrate enhancement factor (SEF) than the one obtained at 400 degrees C, suggesting that the calcination temperature was a determining parameter to enhance SERS activity in current synthetic condition. | Lee, Su-Bin; Paek, Seung-Min; Oh, Jae-Min | Dongguk Univ Seoul, Dept Energy & Mat Engn, Seoul 04620, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea | Paek, Seung-Min/E-4667-2011 | 57211724798; 7102686289; 7402155053 | sban0103@naver.com;smpaek@knu.ac.kr;jaemin.oh@dongguk.edu; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.13 | 2025-07-30 | 6 | 7 | silver nanoparticle; layered double hydroxide; surface-enhanced Raman spectroscopy; porous structure | SERS SUBSTRATE; OPTICAL-PROPERTIES; THERMAL-BEHAVIOR; CALCINATION; NANOCLUSTERS; RECOGNITION; FABRICATION; CHEMISTRY; GROWTH; OXIDES | Layered double hydroxide; Porous structure; Silver nanoparticle; Surface-enhanced Raman spectroscopy | English | 2021 | 2021-02 | 10.3390/nano11020447 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Recent Advances in Gadolinium Based Contrast Agents for Bioimaging Applications | Gadolinium (Gd) based contrast agents (CAs) (Gd-CAs) represent one of the most advanced developments in the application of Gd for magnetic resonance imaging (MRI). Current challenges with existing CAs generated an urgent requirement to develop multimodal CAs with good biocompatibility, low toxicity, and prolonged circulation time. This review discussed the Gd-CAs used in bioimaging applications, addressing their advantages and limitations. Future research is required to establish the safety, efficacy and theragnostic capabilities of Gd-CAs. Nevertheless, these Gd-CAs offer extraordinary potential as imaging CAs and promise to benefit bioimaging applications significantly. | Fatima, Atiya; Ahmad, Md.

| ○ | ○ | Review | Recent Progress in Technetium-99m-Labeled Nanoparticles for Molecular Imaging and Cancer Therapy | Nanotechnology has played a tremendous role in molecular imaging and cancer therapy. Over the last decade, scientists have worked exceptionally to translate nanomedicine into clinical practice. However, although several nanoparticle-based drugs are now clinically available, there is still a vast difference between preclinical products and clinically approved drugs. An efficient translation of preclinical results to clinical settings requires several critical studies, including a detailed, highly sensitive, pharmacokinetics and biodistribution study, and selective and efficient drug delivery to the target organ or tissue. In this context, technetium-99m (Tc-99m)-based radiolabeling of nanoparticles allows easy, economical, non-invasive, and whole-body in vivo tracking by the sensitive clinical imaging technique single-photon emission computed tomography (SPECT). Hence, a critical analysis of the radiolabeling strategies of potential drug delivery and therapeutic systems used to monitor results and therapeutic outcomes at the preclinical and clinical levels remains indispensable to provide maximum benefit to the patient. This review discusses up-to-date Tc-99m radiolabeling strategies of a variety of important inorganic and organic nanoparticles and their application to preclinical imaging studies. | Mushtaq, Sajid; Bibi, Asia; Park, Jung Eun; Jeon, Jongho | Pakistan Inst Engn & Appl Sci, Dept Nucl Engn, PO Nilore, Islamabad 45650, Pakistan; Univ Wah, Dept Chem, Rawalpindi 47040, Punjab, Pakistan; Kyungpook Natl Univ, Dept Appl Chem, Coll Engn, Daegu 41566, South Korea | 57207516170; 57211603495; 57210160353; 35082028100 | sajidmushtaq@pieas.edu.pk;asiabibi.uow@gmail.com;pje1204@knu.ac.kr;jeonj@knu.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 11 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.6 | 2025-07-30 | 29 | 32 | technetium-99m; nanoparticle; molecular imaging; cancer therapy; radiolabeling | IRON-OXIDE NANOPARTICLES; ENTRAPPED GOLD NANOPARTICLES; DRUG-DELIVERY; SILICA NANOPARTICLES; MAGNETIC-RESONANCE; TARGETED DETECTION; IN-VITRO; BIODISTRIBUTION; TC-99M; DENDRIMER | Cancer therapy; Molecular imaging; Nanoparticle; Radiolabeling; Technetium‐99m | English | 2021 | 2021-11 | 10.3390/nano11113022 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Removal of Radioactive Iodine Using Silver/Iron Oxide Composite Nanoadsorbents | Efficient and cost-effective removal of radioactive iodine (radioiodine) from radioactive contaminated water has become a crucial task, following nuclear power plant disasters. Several materials for removing radioiodine have been reported in the literature. However, most of these materials exhibit some limitations, such as high production cost, slow adsorption kinetics, and poor adsorption capacity. Herein, we present silver/iron oxide nanocomposites (Ag/Fe3O4) for the efficient and specific removal of iodine anions from contaminated water. The Ag/Fe3O4 were synthesized using a modified method and characterized via scanning electron microscopy, transmission electron microscopy, and X-ray diffraction analyses. This adsorbent showed a high adsorption capacity for iodine anions (847 mg/g of the adsorbent) in pure water. Next, Ag/Fe3O4 was applied to the removal of radioiodine, and high removal efficiencies were observed in water. In addition, its desalination capacity was retained in the presence of competitive ions and varied pH. After the adsorption process, Ag/Fe3O4 was easily removed from the water by applying an external magnetic field. Moreover, the same operation can be repeated several times without a significant decrease in the performance of Ag/Fe3O4. Therefore, it is expected that the findings presented in this study will offer a new method for desalinating radioiodine in various aqueous media. | Zia, Mah Rukh; Raza, Muhammad Asim; Park, Sang Hyun; Irfan, Naseem; Ahmed, Rizwan; Park, Jung Eun; Jeon, Jongho; Mushtaq, Sajid | Pakistan Inst Engn & Appl Sci, Dept Nucl Engn, PO Nilore, Islamabad 45650, Pakistan; Korea Atom Energy Res Inst, Adv Radiat Technol Inst, Jeongeup 56212, South Korea; Univ Sci & Technol, Radiat Sci & Technol, Daejeon 34113, South Korea; Kyungpook Natl Univ, Coll Engn, Dept Appl Chem, Daegu 41566, South Korea | Raza, Muhammad Asim/GQP-3095-2022; Ahmad, RB/U-3211-2019 | 57078199700; 57197446366; 56262458400; 18436976900; 59823840000; 57210160353; 35082028100; 57207516170 | Mahrukhzia14@gmail.com;masimraza@ust.ac.kr;parksh@kaeri.re.kr;naseem@pieas.edu.pk;Rizwanahmed@pieas.edu.pk;pje1204@knu.ac.kr;jeonj@knu.ac.kr;sajidmushtaq@pieas.edu.pk; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 1.46 | 2025-07-30 | 27 | 28 | adsorbents; radioactive wastes; radioactive iodine; desalination; nanocomposites | Adsorbents; Desalination; Nanocomposites; Radioactive iodine; Radioactive wastes | English | 2021 | 2021-03 | 10.3390/nano11030588 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Surface-Functionalized Separator for Stable and Reliable Lithium Metal Batteries: A Review | Metallic Li has caught the attention of researchers studying future anodes for next-generation batteries, owing to its attractive properties: high theoretical capacity, highly negative standard potential, and very low density. However, inevitable issues, such as inhomogeneous Li deposition/dissolution and poor Coulombic efficiency, hinder the pragmatic use of Li anodes for commercial rechargeable batteries. As one of viable strategies, the surface functionalization of polymer separators has recently drawn significant attention from industries and academics to tackle the inherent issues of metallic Li anodes. In this article, separator-coating materials are classified into five or six categories to give a general guideline for fabricating functional separators compatible with post-lithium-ion batteries. The overall research trends and outlook for surface-functionalized separators are reviewed. | Kim, Patrick Joohyun | Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea | 57195611779 | pjkim@knu.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.62 | 2025-07-30 | 28 | 31 | Li metal anode; functional separator; battery safety; separator-coating materials | DENDRITE-FREE; ION BATTERY; LAYER DEPOSITION; ELECTROCHEMICAL PERFORMANCE; POLYETHYLENE SEPARATORS; THERMAL-STABILITY; ENERGY; INTERFACE; ANODES; HYBRID | Battery safety; Functional separator; Li metal anode; Separator-coating materials | English | 2021 | 2021-09 | 10.3390/nano11092275 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Synthesis, Characterizations, and 9.4 Tesla T2 MR Images of Polyacrylic Acid-Coated Terbium(III) and Holmium(III) Oxide Nanoparticles | Polyacrylic acid (PAA)-coated lanthanide oxide (Ln(2)O(3)) nanoparticles (NPs) (Ln = Tb and Ho) with high colloidal stability and good biocompatibility were synthesized, characterized, and investigated as a new class of negative (T-2) magnetic resonance imaging (MRI) contrast agents at high MR fields. Their r(2) values were appreciable at a 3.0 T MR field and higher at a 9.4 T MR field, whereas their r(1) values were negligible at all MR fields, indicating their exclusive induction of T-2 relaxations with negligible induction of T-1 relaxations. Their effectiveness as T-2 MRI contrast agents at high MR fields was confirmed from strong negative contrast enhancements in in vivo T-2 MR images at a 9.4 T MR field after intravenous administration into mice tails. | Marasini, Shanti; Yue, Huan; Ho, Son Long; Park, Ji Ae; Kim, Soyeon; Jung, Ki-Hye; Cha, Hyunsil; Liu, Shuwen; Tegafaw, Tirusew; Ahmad, Mohammad Yaseen; Ghazanfari, Adibehalsadat; Chae, Kwon-Seok; Chang, Yongmin; Lee, Gang Ho | Kyungpook Natl Univ, Coll Nat Sci, Dept Chem, Taegu 41566, South Korea; Korea Inst Radiol & Med Sci KIRAMS, Div RI Convergence Res, Seoul 01817, South Korea; Korea Testing & Res Inst, Med Device Bio Res Inst, Gwacheon 13810, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, Taegu 41944, South Korea; Kyungpook Natl Univ, Teachers Coll, Dept Biol Educ, Taegu 41566, South Korea | ; Ho, Son Long/P-3183-2015; Ahmad, Mohammad/AAH-2164-2020 | 57200329199; 57200329016; 55659242700; 16319690600; 57203773250; 53865234900; 57189728122; 57208926248; 55983618600; 57203054570; 57200327606; 15743626400; 7501840633; 7404851841 | shantimarasini.sm@gmail.com;yuehuan888@gmail.com;sonlongh@gmail.com;jpark@kirams.re.kr;ksy0188@kirams.re.kr;kihyessi@ktr.or.kr;hyunsil901002@gmail.com;liushuwen0701@gmail.com;tirukorea@gmail.com;yaseen.knu@gmail.com;adibeh.ghazanfari@gmail.com;kschae@knu.ac.kr;ychang@knu.ac.kr;ghlee@mail.knu.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.95 | 2025-07-30 | 18 | 19 | Tb2O3; Ho2O3; nanoparticles; polyacrylic acid-coating; high MR field; MRI | CONTRAST AGENTS; PERFORMANCE; RELAXATION; COMPLEXES; SURFACE; CLEARANCE; PARTICLES; NANORODS; SIZE | High MR field; Ho2O3; MRI; Nanoparticles; Polyacrylic acid‐coating; Tb2O3 | English | 2021 | 2021-05 | 10.3390/nano11051355 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Thermal Evaporation Synthesis of Vertically Aligned Zn2SnO4/ZnO Radial Heterostructured Nanowires Array | The construction of a heterostructured nanowires array allows the simultaneous manipulation of the interfacial, surface, charge transport, and transfer properties, offering new opportunities to achieve multi-functionality for various applications. Herein, we developed facile thermal evaporation and post-annealing method to synthesize ternary-Zn2SnO4/binary-ZnO radially heterostructured nanowires array (HNA). Vertically aligned ZnO nanowires array (3.5 mu m in length) were grown on a ZnO-nanoparticle-seeded, fluorine-doped tin oxide substrate by a hydrothermal method. Subsequently, the amorphous layer consisting of Zn-Sn-O complex was uniformly deposited on the surface of the ZnO nanowires via the thermal evaporation of the Zn and Sn powder mixture in vacuum, followed by post-annealing at 550 degrees C in air to oxidize and crystallize the Zn2SnO4 shell layer. The use of a powder mixture composed of elemental Zn and Sn (rather than oxides and carbon mixture) as an evaporation source ensures high vapor pressure at a low temperature (e.g., 700 degrees C) during thermal evaporation. The morphology, microstructure, and charge-transport properties of the Zn2SnO4/ZnO HNA were investigated by scanning electron microscopy, X-ray diffraction, Raman spectroscopy, transmission electron microscopy, and electrochemical impedance spectroscopy. Notably, the optimally synthesized Zn2SnO4/ZnO HNA shows an intimate interface, high surface roughness, and superior charge-separation and -transport properties compared with the pristine ZnO nanowires array. | Han, Gillsang; Kang, Minje; Jeong, Yoojae; Lee, Sangwook; Cho, Insun | Sungkyunkwan Univ, Sch Adv Mat Sci & Engn, Suwon 16419, South Korea; Ajou Univ, Dept Mat Sci & Engn, Suwon 16499, South Korea; Ajou Univ, Dept Energy Syst Res, Suwon 16499, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | Han, Gill Sang/P-8395-2015; Cho, In Sun/H-6557-2011; Lee, Sangwook/O-9166-2015 | 36463511300; 57224195151; 57224200546; 57203597324; 35739919200 | hangillsang1@gmail.com;alswp965@ajou.ac.kr;dox123@ajou.ac.kr;wook2@knu.ac.kr;insuncho@ajou.ac.kr; | NANOMATERIALS | NANOMATERIALS-BASEL | 2079-4991 | 11 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2021 | 5.719 | 22.7 | 0.32 | 2025-07-30 | 7 | 5 | thermal evaporation synthesis; Zn2SnO4; ZnO; heterostructured nanowires array; interface; charge transport | HYDROTHERMAL SYNTHESIS; OPTICAL-PROPERTIES; HIGH-PERFORMANCE; EFFICIENT; PHOTOELECTRODES; PHOTOANODE; ELECTRODES; TRANSPORT | Charge transport; Heterostructured nanowires array; Inter-face; Thermal evaporation synthesis; Zn<sub>2</sub>SnO<sub>4</sub>/ZnO | English | 2021 | 2021-06 | 10.3390/nano11061500 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Uniform fabrication of hollow titania using anionic modified acrylated polymer template for phase composition effect as photocatalyst and infrared reflective coating | Polymer coatings containing thermal blocking and near-infrared (NIR)-reflective pigments have received much attention for their potential applications in energy-saving fields. A drawback of these coatings is sustainability providing similar long-term performance. Surface cleaning is mandatory to remove contaminants that decrease reflectance. In this study, synthesized hollow titania as photocatalyst was used to impart anti-contamination to infrared (IR)-reflective coatings. A TiO2 shell was selectively formed on an anionic polystyrene core, modified by methacrylic acid. According to sintering temperature, the enhancement of light absorption ability and photocatalytic activity as methyl orange decomposition was observed with phase composition change. The methylene blue decomposition reaction, reflectance measurement, and measuring thermal profiling of coated steel confirmed the manifestation of hollow particles to dust degradation characteristics and the enhancement of reflection and thermal shielding. © 2021 by the authors.

| ○ | ○ | Article | Effects of the Assimilation of Relative Humidity Reproduced From T-PARCII and Himawari-8 Satellite Imagery Using Dynamical Initialization and Ocean-Coupled Model: A Case Study of Typhoon Lan (2017) | Effects of the assimilation of relative humidity (RH) reproduced from dropsonde data from the Tropical cyclones-Pacific Asian Research Campaign for Improvement of Intensity estimations/forecasts (T-PARCII) campaign and Himawari-8 satellite data on the simulation of Typhoon Lan (2017) were investigated herein using a weather research and forecasting model. The lateral boundary and initial conditions were obtained from Global Forecast System (GFS) forecast data. Four experiments varying from the initial vortex, assimilation of the reproduced RH (ARH), and ocean model (OCEAN, three-dimensional Price-Weller-Pinkel upper-ocean circulation model) activation were conducted for 42 h to evaluate tropical cyclone (TC) forecast performance: the GFS experiment and dynamical initialization (DI) experiments such as DI, DI-OCEAN, and DI-ARH-OCEAN, respectively. All track forecast errors were less than 100 km until landfall, that is, up to 36 h. TC intensity forecasts such as the minimum sea-level pressure and maximum surface wind speed were slightly improved in DI-related experiments compared to the GFS experiment. The DI-ARH-OCEAN experiment, in particular, demonstrated improvements in both TC forecasts and convective areas. The ocean-coupled experiments yielded significant sea surface temperature cooling in the rear-right quadrant of TC, forming a stable boundary layer that could suppress the convective activity, particularly in the lower troposphere. These findings support that compared to the original DI method, ARH could improve initial conditions, resulting in more accurate TC forecasts. Furthermore, it may argue the necessity and urgency of regular aircraft surveillance of TCs in the western North Pacific area. | Lee, Jae-Deok; Park, Doo-Sun R.; Ito, Kosuke; Wu, Chun-Chieh | Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu, South Korea; Univ Ryukyus, Dept Phys & Earth Sci, Okinawa, Japan; Natl Taiwan Univ, Dept Atmospher Sci, Taipei, Taiwan | Park, Doo-Sun/U-9448-2019; LEE, Jae-Deok/HPC-4933-2023 | 56972775300; 37117659000; 56864941100; 8987631200 | dsrpark@knu.ac.kr; | JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES | J GEOPHYS RES-ATMOS | 2169-897X | 2169-8996 | 126 | 17 | SCIE | METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 5.217 | 22.9 | 0.43 | 2025-07-30 | 5 | 5 | tropical cyclone; data assimilation; dynamic initialization; WRF | CYCLONE TRACK FORECASTS; GOES-8 WIND INFORMATION; PART I; RAPID INTENSIFICATION; TARGETED OBSERVATIONS; HURRICANE ANALYSES; DROPWINDSONDE DATA; IMPACT; SURVEILLANCE; DROPSONDE | data assimilation; dynamic initialization; tropical cyclone; WRF | Pacific Ocean; Pacific Ocean (North); aircraft; boundary layer; relative humidity; satellite data; sea surface temperature; simulation; surface wind; tropical cyclone; troposphere | English | 2021 | 2021-09-16 | 10.1029/2020jd034516 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Emissions of Tetrafluoromethane (CF4) and Hexafluoroethane (C2F6) From fast Asia: 2008 to 2019 | The perfluorocarbons (PFCs), tetrafluoromethane (CF4) and hexafluoroethane (C2F6), are potent greenhouse gases with very long atmospheric lifetimes. They are emitted almost entirely from industrial sources, including the aluminum and rare earth metal smelting industries that emit them as by-products, and the semiconductor and flat panel display manufacturing industries that use them and vent unutilized amounts to the atmosphere. Despite extensive industrial efforts to quantify and curb these emissions, "top-down" PFC emission estimates derived from atmospheric measurements continue to rise and are significantly greater than reported process- and inventory-based "bottom-up" emissions. In this study, we estimate emissions of CF4 and C2F6 from East Asia, where PFC emitting industries are heavily concentrated, using a top-down approach (a Bayesian inversion) with high-frequency atmospheric measurements at Gosan (Jeju Island, South Korea) for 2008-2019. We also compile and analyze the available bottom-up CF4 and C2F6 emissions in East Asia from industrial and government reports. Our results suggest that the observed increases in global PFC emissions since 2015 are driven primarily by China's aluminum industry, with significant contributions from Japan's and Korea's semiconductor industry. Our analysis suggests that Chinese emissions occur predominantly from the aluminum industry, although their emissions per production ratio may be improving. Our results for Japan and Korea find significant discrepancies between top-down and bottom-up emissions estimates, suggesting that the effectiveness of emission reduction systems (abatement) used in their semiconductor industries may be overestimated. Overall, our top-down results for East Asia contribute significantly to reducing the gap in the global PFC emission budgets. Plain Language Summary CF4 and C2F6, emitted mainly from the aluminum and semiconductor industries, are some of the longest-lived greenhouse gases known, and among the compounds included under the United Nations Framework Convention on Climate Change in the global effort to reduce greenhouse gas emissions and mitigate climate change. Despite significant progress from both industries in understanding and reducing their emissions over the last 3 decades, the global emissions of CF4 and C2F6 modeled using atmospheric measurements continue to rise, and are significantly larger than those currently reported by industry and government. In this study, we estimate CF4 and C2F6 emissions over 2008-2019 in East Asia, where the aluminum and semiconductor industries are heavily concentrated, using a regional inverse model framework combined with measurements at a site in East Asia (Gosan, Jeju Island, South Korea). Our results confirm the dominant role of East Asian emissions in the global budgets of CF4 and C2F6, led by emissions from China's aluminum industry. Our regional emission estimates are significantly larger than those reported for this region, locating a significant source of the global discrepancy between the reported and atmospheric measurements based emissions for these compounds. We analyze key uncertainties that could lead to these discrepancies. | Kim, Jooil; Thompson, Rona; Park, Hyeri; Bogle, Stephanie; Muhle, Jens; Park, Mi-Kyung; Kim, Yeaseul; Harth, Christina M.; Salameh, Peter K.; Schmidt, Roland; Ottinger, Deborah; Park, Sunyoung; Weiss, Ray F. | Univ Calif San Diego, Scripps Inst Oceanog, La Jolla, CA 92093 USA; Norwegian Inst Air Res NILU, Kjeller, Norway; Kyungpook Natl Univ, Dept Oceanog, Daegu, South Korea; Environm Protect Agcy, Climate Change Div, Off Atmospher Programs, Washington, DC USA; Kyungpook Natl Univ, Kyungpook Inst Oceanog, Daegu, South Korea; Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu, South Korea | Muhle, Jens/GPX-3244-2022; Park, Mi-Kyung/J-9643-2017 | 36142937600; 55482250100; 57217629478; 57231463100; 55917306500; 7404491155; 57232849000; 8878471400; 6602378882; 57202398831; 57606109000; 57085459500; 7404027402 | jjkim@ucsd.edu; | JOURNAL OF GEOPHYSICAL RESEARCH-ATMOSPHERES | J GEOPHYS RES-ATMOS | 2169-897X | 2169-8996 | 126 | 16 | SCIE | METEOROLOGY & ATMOSPHERIC SCIENCES | 2021 | 5.217 | 22.9 | 1.64 | 2025-07-30 | 0 | 25 | ATMOSPHERIC GASES; GLOBAL EMISSIONS; PERFLUOROCARBONS; PFCS; INCREASE; CHINA; SF6 | Far East; aluminum; Bayesian analysis; bottom-up approach; estimation method; greenhouse gas; industrial emission; manufacturing; rare earth element; smelting; top-down approach | English | 2021 | 2021-08-20 | 10.1029/2021jd034888 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
