This article describes the synthesis of indium tin oxide (ITO) thin films using solgel processing with a mixture of InCl₃, methanol, and SnCl₂, where the solutions were spin coated onto glass substrates. The combined architecture of black phosphorus on ITO thin films shows promise in its use for transparent electronics, which can also serve as a stepping stone for future solar cell platforms

Synthesis of Octahedral-Shaped NiO and Approaches to an Anode Material of Manufactured Solid Oxide Fuel Cells Using the Decalcomania Method

Micrometer-sized and octahedral-shaped NiO particles were synthesized by microwave thermal treatment at 300 watt power for 15 min in a microwave chamber to be used as an anode material in solid oxide fuel cells. SEM image and particle size distribution revealed near-perfect octahedral NiO microparticle with sizes ranging from 4.0~11.0 μm. The anode functional layer (AFL, 60 wt% NiO synthesized: commercial 40 wt% YSZ), electrolyte (commercial Yttria-stabilized zirconia, YSZ), and cathode (commercial La0.8Sr0.2MnO3, LSM) layers were manufactured using the decalcomania method on a porous anode support, sequentially. The sintered electrolyte at 1450°C for 2 h using the decalcomania method was dense and had a thickness of about 10 μm. The cathode was sintered at 1250°C for 2 h, and it was porous. Using humidified hydrogen as a fuel, a coin cell with a 15 μm thick anode functional layer exhibited maximum power densities of 0.28, 0.38, and 0.65 W/cm2 at 700, 750, and 800°C, respectively. Otherwise, when a commercial YSZ anode functional layer was used, the maximum power density was 0.55 W/cm2 at 800°C

Targeted Degradation of Transcription Coactivator SRC-1 through the N-Degron Pathway

Aberrantly elevated steroid receptor coactivator-1 (SRC-1) expression and activity are strongly correlated with cancer progression and metastasis. Here we report, for the first time, the development of a proteolysis targeting chimera (PROTAC) that is composed of a selective SRC-1 binder linked to a specific ligand for UBR box, a unique class of E3 ligases recognizing N-degrons. We showed that the bifunctional molecule efficiently and selectively induced the degradation of SRC-1 in cells through the N-degron pathway. Importantly, given the ubiquitous expression of the UBR protein in most cells, PROTACs targeting the UBR box could degrade a protein of interest regardless of cell types. We also showed that the SRC-1 degrader significantly suppressed cancer cell invasion and migration in vitro and in vivo. Together, these results demonstrate that the SRC-1 degrader can be an invaluable chemical tool in the studies of SRC-1 functions. Moreover, our findings suggest PROTACs based on the N-degron pathway as a widely useful strategy to degrade disease-relevant proteins.N

Factors associated with health-related quality of life in kidney transplant recipients in Korea.

Health-related quality of life (HRQOL) of kidney transplant recipients is an outcome evaluation after kidney transplants. Therefore, we investigated the associations among perceived health status, social support, self-determination, post-traumatic growth, and kidney transplant recipients' HRQOL. This study involved a descriptive, self-report survey of 163 kidney transplant recipients visiting an outpatient solid organ transplant center in South Korea. Participants' general and transplant characteristics, perceived health status, post-traumatic growth, social support, self-determination, and HRQOL were collected. Data were statistically analyzed using the software SPSS version 25.0. HRQOL showed statistically significant positive correlation with perceived health status (r = .56, p < .001), post-traumatic growth (r = .18, p = .022), social support (r = .25, p = .002), and self-determination (r = .36, p < .001). The factors affecting HRQOL were perceived health status (β = 0.47, p < 0.001), post-transplant occupation (β = 0.17, p = 0.009), and income source (β = -0.13, p = 0.046). The explanatory power of these variables was 34.8% (F = 28.81, p < 0.001). In the subdomains of HRQOL, the factors influencing HRQOL of mental component summary were perceived health status (β = 0.45, p < 0.001), self-determination (β = 0.27, p < 0.001), and education level (β = 0.18, p = 0.006). The explanatory power of these variables was 34.8% (F = 28.81, p < 0.001). To promote the HRQOL of kidney transplant recipients, an institutional system to assist kidney transplant recipients in returning to work needs to be developed. Additionally, creating an environment that allows kidney transplant recipients to act with self-determination, and developing intervention programs that can enhance self-determination will contribute to enhancing the HRQOL of kidney transplant recipients

Synthesis of Submicron Hexagonal Plate-Type SnS 2

SnS2 and Sn1−xTixS2 (x = 0, 0.1, 0.3, 0.5, and 0.7 mol) materials were designed using solvothermal method with the aim to enhance hydrogen production from water/methanol water photosplitting. Scanning electron microscopy revealed hexagonal plates with one side, 3.0 μm in length, in the SnS2 materials. Pure SnS2 showed absorption band edges of above 660 nm, and the absorption was shifted to low wavelengths with the insertion of Ti ions. The evolution of H2 from MeOH/H2O (1 : 1) photosplitting over SnS2 hexagonal plates in the photocatalytic liquid system was 0.016 mL h−1 g−1, and the evolutions were enhanced in Sn1−xTixS2. In particular, 0.049 mL h−1 g−1 of H2 gas was produced in Sn0.7Ti0.3S2 without electrolytes and it increased significantly to more than 90.6% (0.47 mL h−1 g−1 evolutions) at higher pH using 0.1 M of KOH. Based on the UV-visible absorption spectra, the high photocatalytic activity of Sn1−xTixS2 was attributed to the existence of an appropriate band-gap state that retarded recombination between the electrons and holes

High-Efficiently Photoelectrochemical Hydrogen Production over Zn-Incorporated Nanotubes

To investigate the Zn dopant and nanotube morphology effects of TiO2 in electrochemical hydrogen production from the photo-splitting of methanol/water solution, we have designed a Zn-incorporated TiO2 nanotube (Zn-TNT) photocatalyst. The TNT and Zn-TNT materials had a width of 70~100 nm. The hydrogen production over the Zn-TNT photocatalysts was higher than that over the TNT; specifically, 10.2 mL of H2 gas was produced after 9 hours when 0.5 g of 0.01 mol% Zn-TNT was used. The zeta-potential values in aqueous solution determined by electrophoretic light scattering (ELS) had negative surface charges, which was related to the surface stability, and the absolute value was the largest in 0.01 mol% Zn-TNT. On the basis of UV-visible and photoluminescence (PL) spectra results, the high photoactivity of Zn-TNT was attributed to the shift toward the visible region and increase of PL intensity due to the increased number of excited electrons and holes

Fabrication and characterization of inkjet-printed 2D perovskite optoelectronic devices

Article presents the large scale synthesis of solution-processed 2D (CH₃(CH₂)₃NH₃)₂(CH₃NH₃)ₙ − 1PbₙI₃ₙ + 1 (n = 2, 3, and 4) perovskites, a family of layered compounds with composition-tunable bandgap, where inkjet printing was used to fabricate heterostructure, flexible photodetector devices. The flexible, inkjet-printed perovskite 2D heterostructures have significant potential for optoelectronic devices, which can enable broad possibilities with compositional tunability and versatility of the organohalide perovskites

Effective Carbon Dioxide Photoreduction over Metals (Fe-, Co-, Ni-, and Cu-) Incorporated TiO2/Basalt Fiber Films

Mineralogical basalt fibers as a complementary adsorbent were introduced to improve the adsorption of CO2 over the surfaces of photocatalysts. TiO2 photocatalysts (M-TiO2) incorporated with 5.0 mol.% 3d-transition metals (Fe, Co, Ni, and Cu) were prepared using a solvothermal method and mixed with basalt fibers for applications to CO2 photoreduction. The resulting 5.0 mol.% M-TiO2 powders were characterized by X-ray diffraction, scanning electron microscopy, ultraviolet-visible spectroscopy, photoluminescence, Brunauer, Emmett, and Teller surface area, and CO2-temperature-programmed desorption. A paste composed of two materials was coated and fixed on a Pyrex plate by a thermal treatment. The 5.0 mol.% M-TiO2/basalt fiber films increased the adsorption of CO2 significantly, indicating superior photocatalytic behavior compared to pure TiO2 and basalt fiber films, and produced 158~360 μmol gcat-1 L−1 CH4 gases after an 8 h reaction. In particular, the best performance was observed over the 5.0 mol.% Co-TiO2/basalt fiber film. These results were attributed to the effective CO2 gas adsorption and inhibition of photogenerated electron-hole pair recombination
