A small-scale thermoelectric power generator and combustion apparatus, components thereof, methods for making the same, and applications thereof. The thermoelectric power generator can include a burner including a matrix stabilized combustion chamber comprising a catalytically enhanced, porous flame containment portion. The combustion apparatus can include components connected in a loop configuration including a vaporization chamber; a mixing chamber connected to the vaporization chamber; a combustion chamber connected to the vaporization chamber; and a heat exchanger connected to the combustion chamber. The combustion chamber can include a porous combustion material which can include a unique catalytic material.

Thermoelectric power generator and combustion apparatus

The present disclosure relates generally to a composition comprising at least one of iridium diboride and iridium monoboride, and methods of making such. The present disclosure also relates to a composition comprising iridium monoboride and at least one of (a) rows of single iridium atoms and/or (b) one or more clusters of iridium atoms, and methods of making such.

Mechanochemical synthesis of iridium diboride and iridium monoboride

The effects of different perovskite catalysts, catalytic active materials with a crystal structure of ABO, on matrix stabilized combustion in a porous ceramic media are explored. Highly porous silicon carbide ceramics are used as a porous media for a catalytically enhanced matrix stabilized combustion of a lean mixture of methane and air. A stainless steel combustion chamber was designed incorporating a window for direct observation of the flame within the porous media. Perovskite catalytic enhancement of SiC porous matrix with La0.75Sr0.25Fe0.6Cr0.35Ru0.05O3; La0.75Sr0.25Fe0.6Cr0.4O3; La0.75Sr0.25Fe0.95Ru0.05O3; La0.75Sr0.25Cr0.95Ru0.05O3; and LaFe0.95Ru0.05O3, for example, were used to enhance combustion. The flammability limits of the combustion of methane and air were explored using both inert and catalytically enhanced surfaces of the porous ceramic media. By coating the SiC porous media with perovskite catalysts it was possible to lower the minimum stable equivalence ratio.

Perovskite catalysts enhanced combustion on porous media

The presently disclosed and/or claimed inventive concept(s) relates generally to hexagonal osmium boride, OsB, and methods of producing the same. In one non-limiting embodiment, hexagonal OsBis produced by mechanochemical synthesis of osmium and boron in a high energy ball mill.
