Abstract Hydrogen-related defects play crucial roles in determining physical properties of their host oxides. In this work, we report our systematic experimental and theoretical (based on density functional theory) studies the defect states formed hydrogenated-rutile TiO 2 gaseous H atomic H. gas-hydrogenated , incorporated hydrogen tends to occupy oxygen vacancy site negatively charged. The takes interstitial position atom-hydrogenated forming a weak O-H bond with closest ion becomes...
Abstract The canonical Wnt/β-Catenin signaling pathway is widely involved in regulating diverse biological processes. Dysregulation of the results severe consequences, such as developmental defects and malignant cancers. Here, we identified Ube2s a novel activator pathway. It modified β-Catenin at K19 via K11-linked polyubiquitin chain. This modification resulted an antagonistic effect against destruction complex/β-TrCP cascade-orchestrated degradation. As result, stability was enhanced,...
The band gap of rutile TiO2 is reduced remarkably through high-temperature annealing in hydrogen atmosphere, and the absorption visible light hydrogenated-TiO2 can be enhanced. These modifications become more evident with increase pressure. A defect arises near valence upon hydrogenation while conduction remains almost unchanged, which helps for meeting requirements production water splitting. This method could also indicative adjustment other oxide semiconductors.
Hydrogen behavior in oxides has triggered much interest for its scientific and technological importance a wide range of research fields from novel ion conductors to astrochemistry. Here, we report giant conductivity enhancement ZnFe2O4 ferrite insulators the metallic state by over eleven orders magnitude induced electrochemically generated atomic hydrogen at room temperature. The amount incorporated increased an exponential function with time. An activation energy chemisorption was measured...
In this study, a novel and facile approach for the synthesis of ternary boron carbonitride (B-C-N) nanotubes was reported. Growth occurred by heating simple starting materials powder, zinc oxide ethanol absolute at 1150 degrees C under mixture gas flow nitrogen hydrogen. As substrate, commercial stainless steel foil with typical thickness 0.05 mm played an additional role catalyst during growth nanotubes. The were characterized SEM, TEM, EDX, EELS. results indicate that synthesized B-C-N...
A layer of catalyst film on substrate is usually required during the vapor-liquid-solid (VLS) growth one-dimensional (1D) nanomaterials. In this work, however, a novel approach for synthesizing high-purity bamboo-like boron nitride (BN) nanotubes directly commercial stainless steel foils was demonstrated. Synthesis realized by heating and zinc oxide (ZnO) powders at 1200 degrees C under mixture gas flow nitrogen hydrogen. The played an additional role besides VLS nanotubes. addition,...
As a typical kind of high‐efficiency crystalline silicon (c‐Si) solar cell, amorphous/crystalline heterojunction (SHJ) cell is stepping into mass production currently. It great significance to recover Ag from unqualified, broken, and end‐of‐life (EoL) SHJ cells. Herein, facile method including alkaline chemical immersion pyrolysis developed. By immersing the sodium hydroxide (NaOH) aqueous solution for period time, electrodes can be peeled off effectively. The increase concentration ( C s )...
