Synthesis of (h-BN)/SiO2 core–shell powder for improved self-lubricating ceramic composites

A method for in situ preparation of fluorescent AuNPs@AuNCs core/shell nanoparticles by the template of BSA coated gold nanoparticles was developed. The as-prepared AuNPs@AuNCs core/shell nanoparticles possessed advantages such as uniform size, improved monodispersity and excellent fluorescence. The AuNPs@AuNCs core/shell nanoparticles in powder and suspension form were applied to the detection of latent fingermark due to the above properties. The developed latent fingermarks by AuNPs@AuNCs core/shell powder on various surfaces can exhibit excellent ridge details with good contrast between the fingermarks and the substrate. Moreover, under alternative light sources, the latent fingermarks developed with AuNPs@AuNCs core/shell powder work well.

Shell Powder

Abstract Platinum core-shell powder materials are compared and discussed in an oxygen sensor application. The conductive layer materials are prepared by chemical precipitation in the absence or presence of substrate powders, such as YSZ or alumina, to produce platinum powders or platinum/ceramic core/shell composites, respectively. Physical and bulk powder characteristics are presented and discussed. An oxygen sensor is constructed and overall performance is presented to compare the different conductive materials using HTCC tapes and pre-fired substrates.
