Abstract

"Silica sol-gel materials were employed as waste storage containers and matrices for three-dimensional nanoparticle patterning. Due to their porous nature, silica gels provide a substantially empty volume to be impregnated with waste materials. The materials are loaded into the porous gel structure through a liquid diffusion process. Additional reactive solutions, e.g. tools, are also loaded into the gels and a precipitation, e.g. metal-sulfide, ensues. This solid precipitate became immobilized within the silica get matrix. The gel can be vitrified through a viscous flow sintering process, leading to a fully enclosed and stable containment system. Silica sol-gels vitrify at much lower temperatures than the traditional silica glass melting point. Details of the experimental apparatuses and results are presented"--Abstract, page iv.
