Article Therapeutic Effects of TN13 Peptide on Acute Respiratory Distress Syndrome and Sepsis Models In Vivo Background/Objectives: Regulation of acute inflammatory responses is crucial for host mortality and morbidity induced by pathogens. The pathogenesis of acute respiratory distress syndrome (ARDS) and sepsis are associated with systemic inflammation. p38 MAPK is a crucial regulator of inflammatory responses and is a potential target for acute inflammatory diseases, including ARDS and sepsis. We investigated the therapeutic effects of the TAT-TN13 peptide (TN13) on severe inflammatory diseases, including ARDS and sepsis, in vivo. Methods: To establish the ARDS model, C57BL/6 mice were intranasally (i.n.) administered lipopolysaccharide (LPS; 5 mg/kg, 40 mu L) to induce lung inflammation. As a positive control, dexamethasone (DEX; 0.2 mg/kg) was administered intraperitoneally (i.n.) 1 h post-LPS exposure. In the experimental groups, TN13 was administered intranasally (i.n.) at doses of 2.5 mg or 5 mg/kg at the same time point. In the LPS-induced sepsis model, mice received an intraperitoneal injection of LPS (20 mg/kg) to induce systemic inflammation. TN13 (25 mg/kg, i.p.) was administered 1 h after LPS treatment. Control mice received phosphate-buffered saline (PBS). Lung histopathology, inflammatory cell infiltration, cytokine levels, and survival rates were assessed to evaluate TN13 efficacy. Results: TN13 significantly reduced inflammatory cell recruitment and cytokine production in the lungs, thereby mitigating LPS-induced ARDS. In the sepsis model, TN13 treatment improved survival rates by suppressing inflammatory responses. Mechanistically, TN13 exerted its effects by inhibiting the p38 MAPK/NF-kappa B signaling pathway. Conclusions: These results collectively suggested that TN13 could be an effective treatment option for severe inflammatory diseases.

Article Diverse Rotation Curves of Galaxies in a Simulated Universe: The Observed Dependence on Stellar Mass and Morphology Reproduced We use the IllustrisTNG cosmological hydrodynamical simulation to study the rotation curves of galaxies in the local universe. To do that, we first select the galaxies with 9.4 < log(Mstar/M circle dot) < 11.5 to make a sample comparable to that of SDSS/MaNGA observations. We then construct the 2D line-of-sight velocity map and conduct the fit to determine the rotational velocity and the slope of the rotation curve in the outer region (R-t < r < 3 x r(half,*)). The outer slopes of the simulated galaxies show diverse patterns that are dependent on morphology and stellar mass. The outer slope increases as galaxies are more disky, and decreases as galaxies are more massive, except for the very massive early-type galaxies. The outer slope of the rotation curves shows a correlation with the dark matter fraction, slightly better than for the gas mass fraction. Our study demonstrates that the observed dependence of galaxy rotation curves on morphology and stellar mass can be successfully reproduced in cosmological simulations, and provides a hint that dark matter plays an important role in shaping the rotation curve. The sample of simulated galaxies in this study could serve as an important test bed for the subsequent study tracing galaxies back in time, enabling a deeper understanding of the physical origin behind the diverse rotation curves.

Article Green Peas in the Southern Sky: Broadband Color Selection and Spectroscopic Follow-up We present a systematic search for 1696 green pea (GP) galaxy candidates in the southern hemisphere selected from the Dark Energy Survey Data Release 2 and provide preliminary results from spectroscopic follow-up observations of 26 targets chosen among them. Our selection criteria include the colors in the gri bands and compact morphology in the color-composite images. The multiwavelength spectral energy distribution fitting shows that the selected GP candidates exhibit star formation rates up to several tens of M circle dot yr-1. With the mean stellar mass of logM*/M circle dot=8.6 , GP candidates are located at roughly 1 dex above the main sequence of star-forming galaxies at z similar to 0.3. Spectroscopic follow-up observations of the GP candidates with Gemini/Gemini Multi-Object Spectrograph are underway. All 26 targets are spectroscopically confirmed to be at z = 0.3-0.41 and have an [O iii] equivalent width larger than 85 & Aring;, classified to be starbursts with low-to-moderate dust attenuation. These confirmed GPs show a lower metallicity offset from the mass-metallicity relation of local star-forming galaxies, indicating that GPs are less chemically evolved systems at their early stage of evolution.

Article Periodic Low-amplitude Radial Velocity Variations in the Supergiant α Persei alpha Per (HD 20902) is one of the brightest F5 supergiants, located at the blue edge of the instability strip. Several studies reported similar to 100 day periods in the radial velocity (RV) variations in alpha Per, but the reported periods and amplitudes were all different, and the origins of these periodic RV variations remained unknown. We obtained 884 spectra for alpha Per from 2005 to 2020 using the Bohyunsan Observatory Echelle Spectrograph. We found a significant 130.6 day period in RV variations in the generalized Lomb-Scargle periodogram. In addition, the primary 130.6 day period has changed into 66.0 days during the observational duration. The line bisectors, stellar activity indices, such as Ca ii H & K lines and H alpha equivalent widths, and Hipparcos photometric data were analyzed to establish the origins and the periodicity change of the RV variations. We found similar to 130 day periods in line bisector variations, which also changed into similar to 66 days as in RV variations, with a time delay of similar to 400 days leading the RV variations. Either nonradial oscillations or rotational modulation of surface features can affect both RV and line bisector variations. However, nonradial oscillations are more likely to be the origin of RV variations in alpha Per, considering the characteristics of the periodogram of RV variations. The change of the periodicities and the time delay between RV and line bisector variations as observed in this work may provide interesting clues to the ongoing physical processes in alpha Per.

Article Possibility of Using 3.3 μm Polycyclic Aromatic Hydrocarbon Luminosity as a Molecular Gas Mass Estimator We present CO(1-0) observations of 50 star-forming galaxies at 0.01 =-1.09 +/- 0.36 [L-circle dot/(K km s(-1) pc(2))] in the conversion between 3.3 mu m PAH and CO luminosities. The variation in the L-3.3/L-CO ' ratio is not dependent on the galaxy properties, including total IR luminosity, stellar mass, and star formation rate excess. The total gas mass, estimated using the dust-to-gas ratio and dust mass, is correlated with 3.3 mu m PAH luminosity, in line with the prescription using alpha(CO) = 0.8-4.5 covering both normal star-forming galaxies and starburst galaxies. Active galactic nucleus (AGN)-dominated galaxies tend to have a lower L-3.3/L-CO ' than non-AGN galaxies, which needs to be investigated further with an increased sample size. The established L-3.3-L-CO ' correlation is expected to be applicable to wide-field near-infrared spectrophotometric surveys that allow the detection of 3.3 mu m emission from numerous low-redshift galaxies.

Article Resolution enhancement of light field displays using a polarization-dependent virtual-moving liquid crystalline polymer-lenticular lens array with rapid switching operation We propose an effective method to enhance resolution in light field (LF) three-dimensional (3D) displays using a virtual-moving liquid crystalline polymer-lenticular lens array (LCP-LLA) combined with a time-sequential polarization control scheme and rapid lateral switching of periodic focusing operations. The virtual-moving LCPLLA is custom-fabricated by stacking two LCP-LLAs with a half sub-pixel pitch offset, enabling a time-sequential virtual lateral shift of the focal plane. Additionally, we enhance the angular resolution of reconstructed 3D images by optimizing the lateral shifting configurations of the stacked LCP-LLAs in alignment with the sub-pixel arrangement of the display panel. These approaches notably minimize spatial resolution loss while improving angular resolution with a fixed panel configuration, based on the optical properties of the custom-designed virtual-moving LCP-LLA. Experimental validation demonstrates the efficacy of this method, achieving two-fold enhancement in angular resolution for 3D images with 20 viewpoints, without compromising spatial resolution.

Article Seoul National University AGN Monitoring Project. V. Velocity-resolved Hβ Reverberation Mapping and Evidence of Kinematics Evolution We present velocity-resolved reverberation lags of H beta for 20 active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project. We detect unambiguous velocity-resolved structures in 12 AGNs, among which eight objects exhibit symmetric structures, two objects show inflow-like characteristics, and two objects display outflow-like signatures. For two AGNs, we successfully measure the velocity-resolved lags in different years, revealing evidence of evolving broad-line region (BLR) kinematics. By combining our sample with the literature velocity-resolved lags, we find that the symmetric velocity-resolved lags are the most common (40%) type among this sample. The frequency of inflow kinematics is also notable (20%), while outflow kinematics are less common (11%). Our sample significantly expands the previous velocity-resolved reverberation mapping sample in the high-luminosity regime, enabling us to constrain BLR kinematics across a large dynamic range of luminosity.

Article UV-Enhanced Room-Temperature Ammonia Detection Using a Ga2O3/Ti3C2Tx MXene Gas Sensor The present study proposes a Ga2O3/Ti3C2Tx heterojunction-based gas sensor capable of detecting NH3 at room temperature. In this heterojunction, Ga2O3 nanorods, a type of metal oxide, were synthesized on 2-D Ti3C2Tx MXene using a hydrothermal method. The sensor was fabricated by drop casting the Ga2O3/Ti3C2Tx composite onto interdigitated electrodes (IDEs) and evaluated under varying NH3 concentrations with and without ultraviolet (UV) illumination. The fabricated Ga2O3/Ti3C2Tx heterojunction exhibits enhanced reactivity with ammonia gas due to the high surface area of Ga2O3 and the superior electrical conductivity of Ti3 C2Tx, resulting in a synergistic effect that significantly improves NH3 detection performance. In addition, when exposed to UV light at room temperature, the Ga2O3/Ti3C2Tx gas sensor demonstrates an increased response and stable baseline resistance recovery. The response to 25-ppm NH3 increased from 18.68% without UV to 23.47% with UV, highlighting the enhanced performance enabled by UV illumination. These findings indicate the sensor's potential for ammonia detection across a wide concentration range and highlight its promise for commercial applications in various environmental settings.

Article Adsorptive removal of cationic dyes from water with polypyrrole-derived porous carbons Polypyrrole-derived carbons (PpDCs) were obtained via pyrolysis of polypyrrole under various preparation conditions. After characterization, PpDCs were used for the adsorptive purification of water contaminated with organic dyes. One PpDC (PpDC-800) exhibited the highest adsorption capacity (Qo) for cationic dyes (e.g., methylene blue and crystal violet) compared to other adsorbents. The adsorption capacity of PpDC-800 for methylene blue and crystal violet was approximately seven times higher than that of activated carbon. The effective adsorption of cationic dyes (200 mg/L) over PpDC-800 was also observed in water with very low concentrations of methylene blue or crystal violet (1 mg/L), which causes toxicity and affects aesthetics. PpDC-800 showed high selectivity for methylene blue adsorption from an equivalent-weight mixture of anionic methyl orange and cationic methylene blue. Plausible adsorption mechanisms of methylene blue removal, such as electrostatic and π-π interactions, have been suggested. Structural characterization and adsorption mechanism were confirmed using XRD, N2 adsorption, Raman spectroscopy, SEM, XPS, zeta potential analysis, and other techniques.

Article Controlled Formation of Au Nanonetworks via Discrete BTA-Oligo(Acrylic Acid)3 Supramolecular Templates Precise control over molecular dispersity and supramolecular assembly is essential for designing nanostructures with targeted properties and functionalities. In this study, we explore the impact of molecular dispersity in BTA-oligo(AA)3 oligomers on the formation and structural organization of Au nanomaterials in an aqueous system. Discrete and polydisperse BTA-oligo(AA)3 samples are systematically synthesized and characterized to evaluate their role as templates for nanostructure formation. UV-vis spectroscopy and TEM analyses reveal distinct differences in the resulting nanostructures. Specifically, discrete oligomers facilitate the formation of well-defined, interconnected Au nanonetworks with high structural uniformity, even at elevated concentrations. In contrast, polydisperse oligomers facilitated the formation of isolated Au nanoparticles with limited control over morphology and connectivity. These differences are attributed to the greater molecular uniformity and enhanced self-assembly capabilities of the discrete oligomers, which serve as effective templates for directing Au precursor organization and reduction into ordered nanostructures. This study provides mechanistic insight into how molecular dispersity affects the templating and assembly of gold nanomaterials. The findings offer a promising strategy for developing tailored nanostructures with interconnected morphologies and controlled optical and structural properties, paving the way for advanced applications.

Article Enhanced electrochemical performance of flexible carbon substrates via carbonized layer of oxidant-induced polydopamine for high-performance supercapacitors Flexible substrates are essential for advancing energy storage materials in portable and wearable devices. Carbon cloth is a promising option due to its flexibility and lightweight properties, but its high electrical resistance and hydrophobic surface present challenges for solution-based electrolytes. To overcome these issues, a surface modification technique was developed that coats carbon cloth with dopamine and subsequently carbonizes it. This process enhances hydrophilicity while preserving the sp2 carbon structure, significantly improving electrical conductivity. The chemical bath deposition of Ni(OH)2 onto the carbonized polydopamine-coated carbon cloth produced a uniform layer that increased specific capacitance dramatically. At a current density of 1 A/g, the specific capacitance reached 1100F/g, compared to 919F/g for Ni(OH)2 on unmodified carbon cloth. Furthermore, the electrodes maintained high specific capacitance at higher current densities, showcasing superior rate capability. Overall, carbonized polydopamine layers effectively reduce electrical resistivity and hydrophobicity, enhancing the performance of carbon-based materials for energy storage applications.

Article Exploring the Effect of the Polyol Structure and the Incorporation of Lignin on the Properties of Bio-Based Polyurethane This study developed bio-based waterborne polyurethane (BWPU) dispersions containing lignin as a sustainable filler with castor oil (CO), polycaprolactone diol (PCL), or poly(trimethylene ether) glycol (PO3G). The effects of the polyol structure and the presence of lignin on the mechanical performance, thermal stability, water absorption, ethanol resistance, and UV-blocking capabilities of the resulting BWPU samples were evaluated. The results revealed that lignin affects the molecular packing and interchain interactions of CO-based BWPU, thus improving its tensile strength and thermal stability while reducing its water absorption and ethanol permeability. In the PCL-based BWPU, lignin had a minimal impact on water absorption and ethanol resistance but led to greater UV-blocking ability due to interactions between the semi-crystalline matrix of PCL and the aromatic structure of the lignin. In the PO3G-based BWPU, lignin disrupted the polymer network, increasing its water absorption and reducing its ethanol resistance but significantly improving its elongation and UV-shielding behavior. These results highlight the dual role of lignin as a sustainable reinforcing agent and functional additive in enhancing the properties of BWPU. By tailoring the polyol structure and optimizing lignin use, this study demonstrates a framework for the development of eco-friendly PU composites suitable for use as coatings, barriers, UV-shielding films, and packaging Kim, Bomin; Lee, Jihoon; Jang, Sunjin; Park, Jaehyeon; Choi, Jinsil; Lee, Seungyeol; Jung, Joonhoo; Park, Jaehyung Interior & Exterior Mat Dev Team, Hyundai Motor Grp, Hwaseong 18280, South Korea; Kyungpook Natl Univ, Dept Carbon & Fiber Composite Mat, Daegu 41566, South Korea; Kyungpook Nation Univ, Dept Integrat Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Plant Med, Daegu 41566, South Korea; ANPOLY Inc, Pohang 37666, South Korea 58641148700; 59338387300; 57191615594; 58745582800; 58512402700; 56106499600; 58640695700; 59879989800 bomin812@gmail.com; ruta5266@gmail.com; jsjsjsj0501@gmail.com; p0526jh@gmail.com; chlwlstlf321@gmail.com; leesy1123@knu.ac.kr; jjung@anpolyinc.com; parkj@knu.ac.kr; POLYMERS POLYMERS-BASEL 2073-4360 17 5 SCIE POLYMER SCIENCE 2024 4.9 19.7 0 2025-05-07 2 2 bio-based polyurethane; lignin; bio-based polyol; waterborne polyurethane dispersion; sustainability OIL-BASED POLYURETHANE; NANOCOMPOSITES; COMPOSITES; ELASTOMERS bio-based polyol; bio-based polyurethane; lignin; sustainability; waterborne polyurethane dispersion Castor Oil; Ethanol; Lignins; Polyurethanes; Resistance; Tensile Strength; Thermal Stability; Water Absorption; Hydroelasticity; Polyurethanes; Thermal barrier coatings; Bio-based; Bio-based polyol; Bio-based polyurethane; Castor oil; Polycaprolactone diols; Polyurethane dispersions; Property; Waterborne Polyurethane; Waterborne polyurethane dispersion; Tensile strength English 2025 2025-03 10.3390/polym17050604 바로가기 바로가기 바로가기 바로가기
Article Field Data Retrieval for Electric Vehicles and Estimating Equivalent Circuit Model Parameters via Particle Swarm Optimization Data retrieval techniques are crucial for developing an effective battery management system for an electric vehicle to accurately assess the battery's health and performance by monitoring operating conditions such as voltage, current, time, temperature, and state of charge. This paper proposes an efficient approach to retrieve real-world field data (voltage, current, and time) under running vehicle conditions. In the first step, noise is removed from the field data using a moving-average filter. Then, first- and second-order derivations are applied to the filtered data to determine specific data set conditions. After that, a new approach based on zero-crossing is implemented to retrieve the field data. A second-order Randle circuit (SORC) is utilized in this study to analyze the selected field data. Further, a particle swarm optimization algorithm is adapted to estimate the parameters of the SORC. Our experiments indicate that the relative errors of the equivalent circuit model (ECM) are less than 2% compared to the model voltage and real voltage, which is consistent with the stable parameters of ECM.

Article Interfacial bonding effects of various silane treatments for dielectric layers in hybrid bonding and 3D packaging technology A silane-assisted surface functionalization strategy was employed to enhance the interfacial bonding performance of Cu/SiO2 hybrid bonding (HB) for advanced semiconductor packaging applications. A series of silane precursors with varying alkyl chain lengths and terminal functional groups were applied to selectively modify the SiO2 dielectric surface, promoting strong dielectric–dielectric adhesion while preserving Cu–Cu bonding regions. Among the tested silanes, (3-aminopropyl)triethoxysilane (APTES) exhibited the most favorable bonding characteristics by introducing hydrophilic amine groups that facilitate hydrogen bonding and subsequent siloxane crosslinking. The bonding behavior was evaluated by cross-sectional FE-SEM, FT-IR spectroscopy, contact angle measurements, AFM, EDS elemental mapping, and die shear tests. The APTES-treated HB chip achieved the highest bonding strength of 3.2 MPa and exhibited cohesive fracture behavior and void-free dielectric interfaces, whereas long-chain alkyl silanes resulted in reduced adhesion due to increased hydrophobicity and surface roughness. These results confirm that surface functionalization using short-chain silanes significantly improves interfacial bonding at low-temperature (250 °C) without damaging surrounding components. This study presents an applicable and thermally efficient route for enabling fine-pitch HB, emphasizing the importance of silane selection for reliable low-temperature integration in 3D semiconductor packaging. © 2025 The Author(s) Otgonbayar, Zambaga; Jekal, Suk; Noh, Jungchul; Kim, Jiwon; Park, Gyu-Sik; Sa, Minki; Hong, Sungwook Leo; Kim, Myeongjin; Kim, Jeonghun; Yoon, Chang-Min Department of Polymer Science and Engineering, Inha University, Incheon, 22212, South Korea; Program in Environmental and Polymer Engineering, Inha University, Incheon, 22212, South Korea; Department of Chemical Engineering, Hongik University, 94 Wausan-ro, Mapo-gu, Seoul, 04066, South Korea; Program in Environmental and Polymer Engineering, Inha University, Incheon, 22212, South Korea; Program in Environmental and Polymer Engineering, Inha University, Incheon, 22212, South Korea; Program in Environmental and Polymer Engineering, Inha University, Incheon, 22212, South Korea; Department of Mechanical Engineering, Loyola Marymount University, Los Angeles, 90045, CA, United States; School of Energy Engineering, Kyungpook National University, 80 Daehak-ro, Bukgu, Daegu, 41566, South Korea; Department of Chemical and Biomolecular Engineering, Yonsei University, 50 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea; Department of Polymer Science and Engineering, Inha University, Incheon, 22212, South Korea, Program in Environmental and Polymer Engineering, Inha University, Incheon, 22212, South Korea, 3D Convergence Center, Inha University, Incheon, 22212, South Korea 57216926127; 57902700100; 57132103300; 57902916700; 59150508500; 58726756400; 59843140600; 55541419000; 55983391300; 58171619600 myeongjinkim@knu.ac.kr; cmyoon4321@inha.ac.kr; Journal of Industrial and Engineering Chemistry J IND ENG CHEM 1226-086X 1876-794X SCIE CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, CHEMICAL 2024 6 19.7 0 3D packaging; Advanced semiconductor packaging; Hybrid bonding; Low-temperature bonding; Silylation; SiO<sub>2</sub>–SiO<sub>2</sub> dielectric bonding Adhesion; Bond strength (chemical); Chains; Chip scale packages; Contact angle; Diffusion bonding; High-k dielectric; Low temperature operations; Low-k dielectric; Packaging; Silanes; 3D packaging; Advanced semiconductor packaging; Hybrid bonding; Interfacial bonding; Low temperature bonding; Semiconductor packaging; Silylations; SiO 2; SiO2–SiO2 dielectric bonding; Hydrogen bonds; Temperature English Article in press 2025 10.1016/j.jiec.2025.06.045 바로가기 바로가기 바로가기
Review Interfacial Interlocking of Carbon Fiber-Reinforced Polymer Composites: A Short Review The mechanical properties of the carbon fiber-reinforced polymer composites (CFRPs) are dependent on the interfacial interaction and adhesion between carbon fibers (CFs) and polymer matrices. Therefore, it is crucial to understand how modifying the CFs can influence the properties of these composites. This review outlines recent research progress with a focus on the relationship between the interfacial and mechanical properties of CFRPs and provides a systematic summary of state-of-the-art surface modification techniques. These techniques are divided into four categories: (i) wet, (ii) electrochemical, (iii) dry, and (iv) polymer matrix modifications. Several strategies for enhancing the interfacial interactions and adhesion of CFRPs are discussed, providing insights for future trends.
