Patent Title	Inventor(s)	Issue Date	Patent Number
1-100 nm metal ferrite spinel coatings are provided on substrates, preferably by using an atomic layer deposition process. The coatings are able to store energy such as solar energy, and to release that stored energy, via a redox reaction. The coating is first thermally or chemically reduced. The reduced coating is then oxidized in a second step to release energy and/or hydrogen, carbon monoxide or other reduced species. Metal ferrite spinel energy storage devices and methods for making and using same	Weimer, Alan W. , Perkins, Christopher , Scheffe, Jonathan , George, Steven M. , Lichty, Paul	05/29/2012	8,187,731
Prepare silicon nitride-silicon carbide composite powders by carbothermal reduction of crystalline silica powder, carbon powder and, optionally, crystalline silicon nitride powder. The crystalline silicon carbide portion of the composite powders has a mean number diameter less than about 700 nanometers and contains nitrogen. The composite powders may be used to prepare sintered ceramic bodies and self-reinforced silicon nitride ceramic bodies. Silicon nitride/silicon carbide composite powders	Dunmead, Stephen D. , Weimer, Alan W. , Carroll, Daniel F. , Eisman, Glenn A. , Cochran, Gene A. , Susnitzky, David W. , Beaman, Donald R. , Nilsen, Kevin J.	06/11/1996	US 5525556
Silicon carbide/silicon nitride composites are prepared by carbothermal reduction of crystalline silica powder, carbon powder and optionally crsytalline silicon nitride powder. The crystalline silicon carbide portion of the composite has a mean number diameter less than about 700 nanometers and contains nitrogen.
