Summary: The sluggish nature of oxygen reduction reaction (ORR) and the current use of expensive precious metals (platinum [Pt], palladium [Pd], etc.) are barriers to the commercialization and scale-up of fuel cell and metal-air battery technologies. Given this, the development of low-cost non-precious metal-based electrocatalysts with high activity and durability is an area that requires attention. In this study, a cupric oxide (CuO) modified zinc oxide (ZnO) supported on nitrogen-doped carbon (CuO/ZnO/NC-60 0) was reported as a desirable electrocatalyst due to its activity in alkaline medium, durability, and low cost.

Summary: The photocatalytic removal of NO with high selectivity and inhibition of NO2 production has been achieved by synthesizing Au/Bi4Ti3O12 heterojunctions. This is accomplished through the promotion of carrier separation by the built-in electric field of the heterojunction, as well as the transfer of electrons from BTO to Au nanoparticles. Additionally, the surface plasmon resonance effect of the Au nanoparticles further enhances the absorption of visible light, resulting in an excellent NO removal rate of about 48%.

Summary: This study investigates the AlN nucleation layer issue in GaN high frequency telecommunication and power switching systems fabricated after heteroepitaxy on Silicon or Silicon Carbide. It is shown that using 3C-SiC as an intermediate layer can significantly decrease RF propagation losses. Measurements and analyses demonstrate that dopant diffusion into the 3C-SiC pseudo-substrate is confined beneath the interface, and a slightly conductive zone is present beneath the AlN/3C-SiC interface, explaining the low propagation losses obtained for the devices. This work highlights the importance and efficiency of the 3C-SiC intermediate layer as a pseudo-substrate.
