Summary: A one-step method for preparing vertically aligned Co doped MoS2 nanosheets on carbon cloth is reported, showing long-term durability and low voltage characteristics for hydrogen and oxygen production in water electrolysis at different pH conditions. The excellent properties of Co-MoS2@CC are attributed to the uncovering of more active sites and high porosity resulting from Co doping, which enhances conductivity and reduces hydrogen adsorption energy in HER and benefits catalytic active sites in OER.

Summary: In this study, a highly active and durable N-CoP/CeO2 nanowire heterostructure electrocatalyst was developed, showing excellent catalytic activity for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The N-CoP/CeO2 catalyst exhibited low overpotentials of 215 and 74 mV at 10 mA cm-2 in 1.0 M KOH. The assembled water electrolyzer with N-CoP/CeO2 displayed super stability, maintaining 95.9% catalytic activity over 42 days at 1.52 V@10 mA cm-2. Theoretical calculations revealed that the metallic heterostructure interfaces of N-CoP/CeO2 enhanced the electrocatalytic activity through fast electron transfer and optimized adsorption/desorption processes.

Summary: Slow oxygen reduction reaction (ORR) kinetics is limiting the development of fuel cells and metal-air batteries. Carbon-based single-atom catalysts (SACs) have great potential in exploring low-cost and high-efficiency ORR catalysts due to their advantages of high electrical conductivity and maximal atom utilization. The coordination of atoms in carbon-based SACs and the defects in the carbon support significantly affect the adsorption of reaction intermediates, thus influencing the catalytic performance. Therefore, understanding the impacts of atomic coordination on the ORR is of vital importance.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.

Summary: This study investigates the effect of K/Na ratio on the phase structure, ferroelectric domains, and piezoelectric properties of potassium sodium niobate (KNN)-based ceramics. It reveals that high Na+ content leads to large ferroelectric domains, while high K+ content results in local polarity heterogeneity and distinct dielectric relaxational behavior. The balanced local polarity and stress heterogeneities contribute to improved piezoelectricity.
