The use of supercritical fluids in the area of material processing and for particle formation has been known for several years now. The advantages of supercritical fluid processing include mild operating temperatures, production of solvent free particles and easy micro encapsulation of particles. One of the attractive methods of particle processing using supercritical fluid is the Supercritical...

In our current study, supercritical water impregnation (SCWI) was introduced as a unique catalyst preparation method by employing the high diffusivity property of supercritical water. The method allows nano-particles to place on support surfaces in extremely dispersed conditions. The silica-based nanocatalyst granules for this purpose were prepared by initial impregnation of highly porous silic...

Aerogels are a special class of porous material, which have excellent physicochemical properties such as low density, high porosity, high surface area and adjustable surface chemistry. Aerogels were first prepared several decades ago, but never truly commercialized due to their high cost. Technological advancements in the production and quality of different types of aerogel cut costs down and m...
