Mesoporous material
Videos
A mesoporous material is a nanoporous material containing pores with diameters between 2 and 50 nm, according to IUPAC nomenclature. For comparison, IUPAC defines microporous material as a material ha

The Stöber process is a chemical process used to prepare silica particles of controllable and uniform size for applications in materials science. It was pioneering when it was reported by Werner Stöbe
Mesoporous material
…different from that of their bulk structure. A procedure for producing mesoporous materials (silica) was patented around 1970, and methods based on the Stöber process from 1968 were still in use in 2015. It went almost unnoticed and was reproduced in 1997. Mesoporous silica nanoparticles (MSNs) were independently…

This NASA silica aerogel is a thermal insulator that is sufficiently insulating to protect crayons from a Bunsen burner flame.
