Summary: By introducing alkali metal ions (Li/Na/K) into CuxS (x = 1 or 2), the oxygen evolution reaction (OER) performance of copper sulfides can be greatly enhanced. The doping of alkali metal ions increases electrical conductivity and optimizes the adsorption energy of oxygenated intermediates, resulting in improved OER performance. NaCu5S3 exhibits the most optimal overpotential of 271 mV @ 20 mA cm(-2), significantly higher than Cu2S, CuS, and most other copper sulfides. Therefore, the doping strategy of alkali metal ions shows important and promising effects on the design of efficient copper sulfide electrocatalysts.

Summary: In this study, a metal Fe/Co phthalocyanine covalent organic polymers (COPs)/carbon nanotube-based heteroatom-doped carbon electrocatalyst was prepared for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). The obtained CoFe-COP/CNT-700 catalyst exhibited significant specific surface area and structural flaws, and the interaction between Co and Fe elements improved ORR and OER activities. The CoFe-COP/CNT-700 catalyst showed superior catalytic performance compared to Pt/C-IrO2 in 0.1 M KOH solution, with a half-wave potential of 0.847 V and a low potential of 1.67 V at 10 mA/cm2 for ORR and OER, respectively. Furthermore, the CoFe-COP/CNT-700 catalyst demonstrated a power density of 117 mW/cm2 and enhanced stability in zinc-air battery applications. The findings of this study have significant implications for the development of effective bifunctional electrocatalysts for zinc-air batteries.

Summary: The authors find that Ir-doped calcium copper titanate (CCTO) perovskite exhibits ultrahigh mass activity for the acidic oxygen evolution reaction (OER). By substituting Ti with Ir, the metal-oxygen covalency is significantly increased, leading to a reduced energy barrier for charge transfer. CCTO, as a highly polarizable perovskite, possesses low defect formation energy for oxygen vacancy, inducing a high number of oxygen vacancies in Ir-doped CCTO (Ir-CCTO). Electron transfer occurs from the oxygen vacancies and Ti to the substituted Ir, resulting in favorable adsorptions of oxygen intermediates at Ti sites and efficient charge supplies during OER.

Summary: Aluminum oxide (alumina, Al2O3) is a widely used ceramic material due to its excellent dielectric, chemical resistance, and low cost. A novel densifying technique called the powder metallurgy hot isostatic press (PM-HIP) process is reported for the first time, which can directly convert Al2O3 powders into fully densified ceramics in one step. The PM-HIP process facilitates the sintering process and leads to the formation of highly dense dislocation arrays within the entire volume of the sintered body, resulting in unique material properties-processing relationships in the Al2O3 ceramics. The Al2O3 ceramics sintered by PM-HIP exhibit unique mechanical and electrical properties, making them suitable for use in electrostatic chucks.
