Abstract:
A novel method for producing inorganic fine particles, which comprises heating a liquid raw material and applying a shock wave to the material. The method allows the suppression of mutual agglomeration or adhesion of particles in the pulverization of a liquid raw material, such as a slurry of zirconia hydrate particles, for preparing an inorganic raw material powder having a sharp particle size distribution and further allows, in the case of a multi-component system, the homogenization of the chemical composition among the resulting particles and even in the interior of a particle.
Abstract:
An improved hydrogen generation system comprising a multi-port wave reformer in which shock and expansion waves are created in a manner causing head-on colliding shock waves and multi-stage compression where reacting gases within a eight port wave reformer are heated and compressed to thermally crack or decompose one or more fuel sources, such as hydrocarbon fuels, to generate a fuel product containing hydrogen.
Abstract:
A bearing element comprises a bearing element substrate (4) and a sliding layer (5) of a sliding layer material. The sliding layer material comprises a polymeric material and nanodiamonds. The nanodiamonds are surface-functionalised nanodiamonds, they comprise one or more functional groups selected from the group consisting of: hydrogen (-H), hydroxyl (-OH), carboxyl (-COOH), amino (-NH2) and nitro (02N). The nanodiamonds preferably have an average particle size of between about 1 nm and about 10nm. Preferably, the nanodiamonds are detonation produced nanodiamonds. The bearing element may be particularly suitable for automotive applications and may provide enhanced resistance to wear and fatigue.
