A nanoparticle of a decomposition product of a transition metal aluminum hydride compound, a transition metal borohydride compound, or a transition metal gallium hydride compound. A process of: reacting a transition metal salt with an aluminum hydride compound, a borohydride compound, or a gallium hydride compound to produce one or more of the nanoparticles. The reaction occurs in solution while being sonicated at a temperature at which the metal hydride compound decomposes. A process of: reacting a nanoparticle with a compound containing at least two hydroxyl groups to form a coating having multi-dentate metal-alkoxides.

A lithiated carbon phosphonitride material is made by, for example, reacting P(CN)with LiN(CN)in solution (for example, dimethoxyethane or pyridine), then drying the solution to obtain the product. The material is a thermoset that is stable to over 400&#xb0; C. and exhibits up to 10S&#xb7;cm2 of Liconductivity.

A nanopowder and a method of making are disclosed. The nanopowder may be in the form of nanoparticles with an average size of less than about 200 nm and contain a reactive transition metal, such as hafnium, zirconium, or titanium. The nanopowder can be formed in a liquid under sonication by reducing a halide of the transition metal.

Preparation of nanopowders of reactive metals via reduction under sonication

A method of preparing a nanomaterial comprising boron includes sonicating a boron trihalide and/or boron alkoxide in a hydrocarbon solvent with an alkali metal under an inert atmosphere to form a dark solid, and annealing the dark solid at a temperature sufficient to sublime alkali metal salt therein, thereby obtaining a boron nanomaterial. Reacting with a Group IVB metal produces a metal boride, and combining an alkali metal salt of a hydrocarbon with the boron trihalide prior to sonicating produces a carbonaceous boron material.

The present invention is directed to a method for producing novel metal nanoparticles and nanomaterials. The method involves mixing one or more metal halide starting materials, one or more lithium reducing agent and one or more solvents. In an exemplary embodiment, the resultant metal nanoparticles are substantially free from impurities and have a novel porous and substantially hollow structure.

Single crystals of binary and ternary compounds of alkaline earth and a chalcogen, with or without a transition element, are grown by: charging a reaction vessel with an alkaline earth chalcogenide, with or without a transition element or a halide thereof, an acidic mineralizer, and anhydrous ammonia to where the fill factor in the reaction vessel is 30-95%; sealing the reaction vessel to the outside atmosphere; heating the contents of the reaction vessel to a temperature of at least 300.degree. C. until single crystal materials visible to the eye form in the reaction vessel; cooling the contents of the reaction vessel; and extracting the single crystal materials from the reaction vessel.
