Summary: In this study, tungsten was successfully plated on the surface of diamond using the thermal diffusion method. Different process parameters were investigated for their effects on the thermal conductivity of diamond/copper composites. The results showed that plating tungsten on diamond improved the interface bonding, with the integrity and uniformity of the coating being more important factors for high thermal conductivity. Furthermore, annealing the tungsten-plated diamond enhanced the metallurgical bonding between the coating and the diamond, leading to further improvement in thermal conductivity.

Summary: A 20 nm SiC nanocoating was prepared on crushed diamond particles using sol-gel and in situ reaction methods. The 50 vol% SiC-coated diamond particles reinforced 6061Al composites were fabricated by vacuum hot pressing. The composite showed improved interfacial thermal conductance due to the presence of SiC at the diamond-Al interface, resulting in a high thermal conductivity of 485 W/mK.

Summary: The application of diamonds for thermal management of solid-state lasers has attracted increasing interest. However, the problem of synthesizing high-performance diamonds has hindered the development of advanced heat management. In this study, diamond was deposited on a Ti:sapphire substrate using a microwave plasma chemical vapor deposition method, and the adhesion between the diamond film and the substrate was improved by using a Cr interlayer. The stable interface adhesion was attributed to the strong carbon adsorption capability of the Cr surface, and the addition of oxygen during the deposition process addressed the issue of increased non-diamond phase. Raman spectroscopy showed that the diamond film deposited on the Cr interlayers had compressive stresses and increased thermal diffusion coefficient by 17%, offering a promising potential for high-power solid-state laser heat spreaders.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
