A center flare tip assembly (16) and plenum flare tip assembly (18) with arms (20), having the outside of the center flare tip assembly (16), both inside and outside of the tips (18), the outside of the arms (20), and/or adjacent features of the flare tip (12) are covered with a high emissivity thermal layer (14) with an emissivity greater than 0.85. This reduces flare metal temperatures by thirty percent (30%) or greater, and increases flare life by two (2) to five (5) times current life.

A nanocomposite has a core-shell structure with an outer shell and an inner core. The, outer shell is a graphitized carbon film, and the inner core contains nickel oxide and alumina, with a nickel oxide content of 59%-80%, an alumina content of 19%-40%, and a carbon content of not more than 1%, based on the total weight of the nanocomposite. The process for catalytic combustion of volatile organic compounds may utilize the nanocomposite as a catalyst.

A method for forming a sintered composition including providing a slurry precursor including a lithium-, sodium-, or magnesium-based compound; tape casting the slurry precursor to form a green tape; and sintering the green tape at a temperature in a range of 500° C. to 1350° C. for a time in a range of less than 60 min to form a sintered composition, such that the slurry precursor further includes a solvent and dispersant. The dispersant may include an amine compound, a carboxylic acid compound, or combinations, mixtures, or salts thereof.

A method for producing a lithium-transition metal composite oxide, including steps of: preparing a mixture including a lithium-containing compound and a transition metal compound; obtaining a molded body of the mixture; and sintering the molded bodies in a container having at least one vent hole, to obtain sintered bodies.

Embodiments relate to an improved hydroflux assisted densification process that introduces a transport phase (formed by the introduction of water during the process to suppress melting temperatures) for sintering, the transport phase being a non-aqueous solution. The process can facilitate sintering at low temperature ranges (at or below 300° C.) to yield densification>90% without the need for additional post-processing steps that otherwise would be needed if conventional processes were used. Control of the pressures and water content used during the process can enhance densification mechanisms related to dissolution-reprecipitation, allowing for a greater range of compositional spectra of materials that can be densified, a reduction of the amount of transport phase needed, a reduction of impurities and an improvement of properties in the densified material. Certain hydrated acetate powders can be used to generate a hydroxide mixture flux that is better for the low-temperature densification process.
