Summary: The study investigated the effects of BN content in porous SiC ceramics on their electrical, thermal, and mechanical properties in N2 and Ar atmospheres. It was found that the electrical resistivity was mainly controlled by the sintering atmosphere, while the thermal conductivity and flexural strength were more influenced by porosity and necking area changes between SiC grains.

Summary: The investigation on hybrid structures made from graphene/hexagonal boron nitride and 2H-molybdenum disulfide (G/BN@MoS2) monolayers reveals their superior properties and potential applications. The implanted hexagon of G or BN in MoS2 alters its electronic properties, making G@MoS2 (I,II) metallic, BN@MoS2 (I) an n-type conductor, and BN@MoS2 (II) a semiconductor. The molecular adsorption studies indicate that these hybrid structures may be suitable for oxygen reduction reactions, NH3-based hydrogen production, and filtration of various gases.

Summary: Hexagonal boron nitride (h-BN) is successfully incorporated into polymer-derived SiCN ceramics, improving their mechanical properties and reducing dielectric loss. The presence of BN reduces the number of pores and prevents crack expansion, leading to enhanced mechanical strength. Additionally, BN weakens the polarization relaxation behavior, resulting in lower dielectric loss.

Summary: By using different forms of materials, metal-free photocatalysts were synthesized and their photodegradation performance difference was clarified. The BCQD showed good fluorescence and up-conversion fluorescence performance. BCN/BCQD-350 exhibited the highest removal efficiency for TC, conforming to the pseudo-second-order kinetic and Langmuir isotherm models. The photoactive species capture experiments revealed the contributions of different species to TC photodegradation, with .O-2(-) playing the largest role. The TC photodegradation by BCN/BCQD-350 started with the dehydration step and had a higher removal rate compared to other materials.
