Latest Patents

One of his latest patents is for an in-situ passivation and insulation layer for a flexible thermal protection system (FTPS). This innovation involves a lightweight flexible boron nitride nanotube (BNNT) mat or fabric that enhances thermal stability and shielding capabilities under hypersonic thermal flux. The BNNT mat effectively reduces stagnation temperature and maintains a low regression rate. Additionally, an in-situ passivation layer can be formed on the BNNT mat under high thermal flux, minimizing the penetration of atmosphere, heat, and radiation. This layer also diffuses heat throughout the mat laterally and radially, preventing localized excessive heat. Another significant patent involves the fabrication of metallic hollow nanoparticles. This process utilizes dendrimer molecules to create metal and semiconductor nanoshells, particularly transition metal nanoshells. The method involves attaching metallic colloids or ions to amine groups on the dendrimer surface, leading to the formation of hollow nanoparticles with adjustable void sizes.
