I'm not sure, but I think that this is colloidal silica. It's super-easy to make (from a $3 bag of finely-milled silica from a ceramics supply store, and some water). It's also commonly available as a filler for epoxy resin. I'm sure they put a lot of work into the uses and research and all, but colloidal silica has been around for a long time and it, if it was so revolutionary, it would have been more more widely used already.
