Abstract: Provided herein is a novel silica-supported nickel nanocomposite and a novel one-pot solution combustion synthesis of that nanocomposite. The method allows the synthesis of small size nickel nanoparticles (e.g., 3 nm to 40 nm) for which a considerable percentage of nickel is inserted into silica, experiencing strong metal-support interaction. These exceptional physicochemical properties make them desirable for various industrial applications, such as electronic, heterogeneous catalysis as well as conversion and storage of energy.

Abstract: This invention relates to a novel nickel catalyst and a novel one-pot solution combustion synthesis of that catalyst for the CO2 reforming and low temperature steam reformation of methane. The novel nickel catalyst has exceptional activity for dry reforming and steam reforming of methane, and exhibits excellent resilience to deactivation due to carbon formation.

Abstract: Certain embodiments of the present invention may be directed to a transistor structure. The transistor structure may include a semiconductor substrate. The semiconductor substrate may include a drift region, a collector region, an emitter region, and a lightly-doped/undoped region. The lightly-doped/undoped region may be lightly-doped and/or undoped. The transistor structure may also include a heterostructure. The heterostructure forms a heterojunction with the lightly-doped/undoped region. The transistor structure may also include a collector terminal. The collector terminal is in contact with the collector region. The transistor structure may also include a gate terminal. The gate terminal is in contact with the heterostructure. The transistor structure may also include an emitter terminal. The emitter terminal is in contact with the lightly-doped/undoped region and the emitter region.
