(30.0 vs. 55.5% in the peripheral process; 15.7 vs.  https://www.selleckchem.com/products/bpv-hopic.html  24.4 % in spiral ganglion neuron). The results suggest that calretinin-poor cochlear nerve fibers may be selectively lost after the hyperglycemic insults. The finding also supports a calretinin's neuroprotective role against diabetic neuropathy in cochlear afferent neurons.New triazene based metal complexes such as Cu[1-(phenyldiazenyl)piperidine]2Br₂ (BTACHCuBr₂), Cu[1-(phenyldiazenyl)piperidine]2Cl₂ (BTACH-CuCl₂), Ni[1-(phenyldiazenyl)piperidine]2Cl₂ (BTACH-NiCl₂ · 6H₂O), Cu[2,2,6,6-tetramethyl-1-(phenyldiazenyl)piperidine]2Cl₂ (BTACM-SnCl₂), Ti[2,2,6,6-tetramethyl-1-(phenyldiazenyl)piperidine]2Cl₂ (BTACM-TiCl₂) were synthesized. All of the five compounds did not absorb in the visible light wavelength region and it does not have the color change disadvantage when using as an additive in polymerization. All materials also had thermal stability up to 245 °C. Among the synthesized compounds, BTACH-CuBr₂ showed the best radical inhibitor property when n-hexyl acrylate monomer was polymerized with the synthesized metal complexes at 150 °C isothermal condition. It exhibited more than 5 times of the polymerization delayed initiation compared to other synthesized metal complexes cases.In this study, the effect by Iron with nickel-based catalyst for the combined steam and carbon dioxide reforming of methane was investigated. Fe-promoted and un-promoted Ni-Mg-Ce/γ-Al2O3 catalysts were prepared by co-impregnation and evaluated in a quartz fixed-bed reactor at H₂OCO₂CH₄ ratios of 0.911 and a temperature of 1073 K under atmospheric pressure. The physicochemical properties of the catalysts were investigated by N₂ adsorption-desorption, XRD, H₂-TPR, CO₂-TPD, TGA and FE-SEM. The iron-supported catalysts showed improved resistance to carbon deposition and suppressed sintering of nickel. As a result, NMC-Fe(5) showed the lowest coke and high stability over 70 h among all other catalysts.A Co₂MnSi Heusler alloy has been prepared by mechanical alloying (MA) method successfully using a mixture of elemental Co50Mn25Si25 powders. A two-phase mixture of amorphous phase and remaining Mn were obtained after 5 hours of MA without any evidence for the formation of Co₂MnSi alloys. The saturation magnetization of MA powders decreased with MA time due to the magnetic dilution by alloying with nonmagnetic Mn and Si elements to 48 emu/g after 5 hours of MA. On the other hand, a Co₂MnSi single phase was obtained by MA after 3 hours and subsequently heat treated up to 650 °C. X-ray diffraction result showed that the average grain size of Co₂MnSi Heusler alloys prepared by MA for 5 hours and heat treatment to be in the range of 85 nm. The saturation magnetization of Co₂MnSi Heusler alloys prepared by MA and heat treatment reached a maximum value of 112 emu/g for 5 hours MA sample. It was also observed that the coercivity of 5 hours MA sample annealed at 650 °C was fairly low value of 27 Oe.In this study, we investigated the electrochemical effects of morphological changes using BaSnO₃ (BSO) of various shapes (columns, hollow rods, spheres) as anode materials for Li-ion batteries. The BSOs were prepared by hydrothermal method and their electrochemical properties were evaluated using galvanostataic charge/discharge and CV test. As a results, columnar BSO exhibits the best electrochemical properties, as an inert material, BaO can contribute to Li storage because of higher electrical conductivity. This results suggest that the formation of column shape can lead to improved electrochemical properties as anode materials of secondary battery.Perovskite solar cells (PSCs) represent the third generation of solar cells that comprise a semiconductor electrode, a counter electrode, and an electrolyte. Perovskite solar cells (PSCs) have been comprehensively researched and led to an impressive improvement in a short period of time as cheaper alternatives to silicon solar cells due to their high energy-conversion efficiency and low production cost. Tin oxide (SnO₂) has attracted attention as a promising candidate for electron transport material of perovskite solar cells, because it can be easily processed by low annealing temperature and solution processing method. However, in the fabrication of SnO₂ electron transfer layer (ETL) via the conventional solution method, it is greatly difficult to increase the size of the substrate by the solution treatment method or to commercialize it. In this work, we report the photovoltaic characteristics of SnO₂ based electron transport layer for perovskite solar cells (PSCs) fabricated by the thermal-evaporation processing method. The deposited SnO₂ layer with the thermal evaporator is known to be not crystallographically stable. To solve this problem, we performed the annealing process at relatively low temperature (below 200 °C). As a result, we could confirm the optimum annealing temperature and we could demonstrate PSCs with thermally deposited SnO₂ as the compact electron transport layer through a low-temperature annealing process. It would contribute to new opportunities in commercialization and development of perovskite solar cells.We explore the effect of high-speed blade coating on electrical characteristics of conjugated polymer-based thin-film transistors (TFTs). As the blade-coating speed increased, the thickness of the polymer thin-film was naturally increased while the surface roughness was found to be unchanged. Polymer TFTs show two remarkable tendencies on the magnitude of field-effect mobility with increasing blade-coating speed. As the blade-coating speed increased up to 2 mm/s, the fieldeffect mobility increased to 4.72 cm²V-1s-1. However, when the coating speed reached 6 mm/s beyond 2 mm/s, the field-effect mobility rather decreased to 3.18 cm²V-1s-1. The threshold voltage was positively shifted from 2.09 to 8.29 V with respect to increase in blade-coating speed.Compared with conventional semiconductor quantum dots, hybrid SiO₂ coated CdTe QDs exhibited high stability, long fluorescent lifetime, high photoluminescence quantum yields, and well biocompatibility. In this paper, CdTe QDs with tunable PL from green to red emitting were prepared by an aqueous synthesis. A sol-gel process resulted in CdTe QDs coated with a hybrid SiO₂ shell contained CdS-like clusters to obtain red-shifted PL spectra, increased PL efficiency and high stability. The clusters were formed by the reaction of Cd2+ and S2- ions generated via the decomposition of thioglycolic acid. The clusters around CdTe cores created a core-shell structure which is very similar with traditional semiconductor core-shell QDs. After being coated with a hybrid SiO₂ shell, the PL of green-emitting naked CdTe QDs was red-shifted largely (~30 nm) while the PL of yellowemitting CdTe QDs revealed a small red-shifted (~20 nm). Furthermore, The PL of red-emitting naked CdTe QDs was red-shifted much small (less than 10 nm).
