Summary: In this study, a solid-liquid-air triphase bio-photocathode based on a superhydrophobic three-dimensional porous micro-nano-hierarchical structured CuxO@TiO2 film was reported, which can accurately detect H2O2.

Summary: A strategy for preparing nitrogen-doped porous carbon (NPC-Co) using a dual-template method is reported. PtCo metal nanoparticles (NPs) were added to develop a catalyst (PtCo/NPC-Co) with high catalytic performance for the oxygen reduction reaction (ORR). Polydopamine was selected as the carbon and nitrogen source because it can complex metals, encapsulate templates, and reduce metals. By using ZnO and Co NPs as a double template, a carrier (NPC-Co) with a high mesoporous ratio and high N content was obtained. The interaction effect between NPC-Co and PtCo NPs enhanced the overall electrocatalytic performance of PtCo/NPC-Co, which exhibited excellent catalytic performance and durability for oxygen reduction.

Summary: This paper examines the wetting behavior of copper droplet on a graphite substrate using molecular dynamics simulation. It finds that the wetting process is influenced by Ar pressure, with hindered wetting at low temperatures and promoted wetting at high temperatures. However, beyond a certain Ar pressure, further increase does not improve wetting, and Ar pressure increases the potential of mean force between the copper droplet and the graphite substrate, making detachment more difficult.

Summary: In this paper, the regulation of crystal structure and orientation during direct current (DC) electrodeposition for achieving performance control of electrodeposited copper films was investigated. It was found that electrolyte aging during continuous DC electrodeposition in acidic electrolytes containing additives promoted spontaneous transformation of copper crystal structure. A special crystal structure composed of vertical twins with high aspect ratio and (220) orientation was revealed, which was mainly attributed to energy minimization in the deposited film. The generation priority of vertical twins was found to be between the equiaxed structure (UD-type) and the (1 1 1) textured columnar structure (FT-type). Complex interactions and degradation of additives were identified as the driving forces for crystal transformation. Additionally, the surface roughness changed with the transformation process of the crystal structure, providing a potential method for regulating the surface roughness of copper films.

Summary: In this study, PH13-8Mo stainless steel parts doped with cerium were fabricated and compared with undoped parts. The doping of cerium improved the microstructure, phase constituents, and tensile properties of the stainless steel. The results showed that doping with cerium enhanced the mechanical stability of austenite, improved the sphericity of oxide inclusion, and increased the ultimate tensile strength and fracture elongation of the PH13-8Mo parts. The improved strength and ductility were attributed to the strengthening effects of nanoscale precipitation and grain refining, as well as the enhanced inclusion sphericity and coherency between the inclusion and matrix.

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.
