Abstract: A method and apparatus by which liquid feedstock suspensions containing fine particles, micron- and nano-sized, are injected, with sufficient droplet velocity, preferably axially, into a plume of a thermal spray apparatus for the production of high-quality nanostructured coatings allows complete entrainment of the droplets in the plume, while the injection orifice remains potentially blockage-free for long periods of operation. The method and apparatus permit delivery at a low flow rate and with sufficient velocity to permit effective deposition, while reducing obstructions for a suspension feedstock delivery system and permits suspension feedstock to be controlled and delivered with reduced sensitivity of the spray process on the injection conditions to enable production of nanostructured coatings.

Abstract: A method and product derived therefrom for consolidating nanoparticles to form particles in a micrometric size distribution. The method preserves the nanoparticles with the resultant micrometric particles. The primary processing operation is milling.

Abstract: This invention relates to a method by which liquid feedstock suspensions containing fine particles, micron- and nano-sized, are injected, with sufficient droplet velocity, preferably axially, into a thermal spray apparatus for the production of high-quality nanostructured coatings. The method allows complete entrainment of the droplets in a high temperature gas stream, while the injection orifice remains potentially blockage-free for long periods of operation.

Abstract: Disclosed is a method for rapidly carrying out a hydrogenation of a material capable of absorbing hydrogen. It was discovered that when a powder of a material capable of absorbing hydrogen is ground under a hydrogen pressure, not at room temperature but at a higher temperature (about 300° C. in the case of magnesium) and in the presence of a hydrogenation activator such as graphite and optionally a catalyst, it is possible to transform completely the powder of this material into a hydride. Such a transformation is achieved in a period of time less than 1 hour whereas the known methods call for periods of time as much as 10 times longer. This is an unexpected result which gives rise to a considerable reduction in the cost of manufacture of an hydride, particularly MgH2.
