In this study, the growth kinetics of silicon and germanium nanowires synthesized by chemical vapor deposition using a vapour-liquid-solid growth method catalyzed by gold were examined. The effects of temperature, partial pressure of the precursor gas, and different carrier gases on the growth rate were analyzed. Optimal conditions for nucleation in the nanowire growth process were identified.

Summary: Boosted CO2 hydrogenation to methanol was achieved by introducing an appropriate amount of Au into conventional Cu-based catalysts. The Au0.005Cu/ZnO bimetallic catalyst exhibited the highest methanol production rate. The formation of Au-Cu alloy was confirmed on the AuxCu/ZnO bimetallic catalysts. Experimental characterizations and density functional theory (DFT) calculations revealed the intrinsic active sites at the metal-oxide interfaces with oxygen vacancies. The promotion effect of Au in bimetallic catalysts was attributed to the increase in active sites, facilitation of CO2 activation, and modification of intermediate adsorption. This study developed a promising Au0.005Cu/ZnO bimetallic catalyst with a trace amount of Au (only 0.4 wt%) and provided insight into the reaction mechanism of Au-promoted Cu/ZnO catalysts for methanol synthesis via CO2 hydrogenation.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
