Summary: The role of dopants on deformation and mechanical properties of 4H silicon carbide (4H-SiC) was investigated using nanoindentation. It was found that different dopants can significantly affect the hardness, elastic modulus, and fracture toughness of 4H-SiC, as well as the formation of dislocations and cracks during nanoindentation. Moreover, polymorph transitions from 4H-SiC to amorphous SiC and 3C-SiC were observed. These findings provide valuable insights for the design of processing methods for differently doped 4H-SiC substrate wafers.

Summary: Composite coatings with variable Sr contents were prepared on the surface of Ti13Nb13Zr alloy using microarc oxidation and hydrothermal treatment. The coatings exhibited rod-like HA/Sr-HA crystals and showed good hydrophilicity. The coatings with different Sr contents had varying degrees of apatite coverage, with the 40-Sr sample having the best coverage. Sr addition improved the apatite induction ability of the coatings, but the effect was limited and decreased when Sr doping exceeded 70%.

Summary: Developing high-performance electrocatalysts for hydrogen evolution reaction in alkaline media is challenging but desirable for water splitting. A wet chemistry method was used to synthesize RuCu nanoflowers with tunable atomic ratios. The Ru3Cu NFs exhibited excellent catalytic properties, requiring only 55 mV for a current density of 10 mA cm(-2) and showing minimal decay after 2000 cycles. The flower-like structure and introduction of Cu improved the HER performance by providing more active sites and modulating the electronic structure of Ru.

Summary: We investigated the crack-healing mechanism of 4H silicon carbide (4H-SiC) and found that high-temperature thermal annealing in the air atmosphere effectively heals indentation-induced cracks in undoped 4H-SiC by the formation and viscous flow of SiO2. Nitrogen doping assists the atomic diffusion and crack healing of 4H-SiC, while vanadium doping hinders the healing process. The padding of glassy SiO2 is found to effectively recover the bending strength of indented 4H-SiC samples.

Summary: This work investigates the influence of erbium (Er) doping on the SiNxOy/c-Si interface, and found that activated Er3+ ions can result in a higher positive charge density, leading to band bending and deeper depletion regions. Through deep-level transient spectroscopy (DLTS), a higher density of interface states and wider energy distribution were observed in the Er-doped samples. Energy dispersive X-ray spectroscopy (EDX) analysis further supports the interaction between Er impurities and intrinsic defects at the interface.

Summary: In this study, three types of core-shell nanocrystals, Au73Pd27@Pt, Au66Pd34@Pt, and Pd@Pt, were successfully constructed using lattice engineering. The strain effect and ligand effect caused by Au were found to enhance the activity of Pt in the electrocatalytic CO2 reduction reaction (EOR). In situ FTIR studies confirmed that the EOR processes on these nanocrystals were dominated by the C2 pathway, which explained the enhancement of EOR activity by the faster kinetics of the C2 pathway producing acetate or acetaldehyde.
