Abstract: A one-step process to synthesize narrow band gap TiO2—TiC core-shell particles is described. A mixture of a fuel source, particularly a hydrocarbon, and a titanium precursor is detonated with a source of oxygen in a constant volume reaction vessel to produce TiO2—TiC core-shell particles. This process can synthesize TiO2—TiC core-shell structures with tailored morphology, size, phase, absorption behavior, and other hybrid morphologies with different properties depending on the Ti/C ratio used in the feed.

Abstract: Graphene coated hollow glass microspheres may be easily prepared by mixing Pristine Reactive Graphene Particles with hollow glass microspheres under conditions to associate the Pristine Reactive Graphene Particles on the external surface of the hollow glass microspheres by chemical coupling with a silane coupling agent to form graphene coated hollow glass microspheres. Graphene coated hollow glass microspheres prepared by the methods as described herein are also provided. In an embodiment, graphene coated hollow glass microspheres comprise a graphene coating formed from Pristine Reactive Graphene Particles associated on the external surface of the hollow glass microspheres by chemical coupling with a silane coupling agent.

Abstract: Apparatus and processes for high-yield production of syngas components via combustion of a carbon-containing material and an oxygen-containing material are provided. Syngas components are generated in an exothermic, combustion reaction with only minor quantities of carbon dioxide, water, and elemental carbon produced.

Abstract: An actuator device comprises an enclosed volume region defined by a housing body and a movable surface, such that at least a portion of the enclosed volume region is expandable from an initial volume state to an enlarged volume state. An electrically conductive porous material is disposed in the enclosed volume region, wherein the electrically conductive porous material has a mass density of from about 0.5 mg/cc to about 100 mg/cc, and wherein at least about 90% of the electrically conductive porous material is a carbonaceous material. A first electrode and a second electrode are configured to pass an electric current through the electrically conductive porous material. When an electric current is passed through the electrically conductive porous material, air disposed in the enclosed volume region expands and displaces the movable surface. A method of displacing a movable surface in an actuator device is also described.
