    摘要： A new low temperature method of reducing metallic salts, both inorganic and organic to metallic nanoparticles has been discovered. The reduction reaction is carried out in low boiling point monoalkylethers of ethylene glycol and mixtures of this solvent with alkane diols. Metallic nanoparticles are produced with size range of 1–100 nm.

    摘要： The present invention is a polyol method for making composite particles of two or more immiscible transition metals, where these particles are of nanoscale dimensions, and where the constituent metals are of essentially nanocrystalline morphology. The method of the invention has the steps of (1) dissolving or suspending two or more precursor metal compounds in an alcohol or polyol (diol, triol, etc.) solution, and (2) taking the solution or suspension to a temperature where the metal compound reduces, causing the first and second metals to form nanoscale composites. The term “polyol solution” will be used herein to describe solutions that contain either alcohol or polyol.

    摘要： Thin films or coatings having a thickness of about 100 nanometers or larger are made of nanostructured particles which have a particle size less than 100 nm (i.e. 0.1 micron) by thermally spraying a solution of a liquid coating precursor feedstock onto a substrate to form the film or coating. By thermal spraying with different precursor feedstock solutions, coatings can be made with more than one layer. Also, by varying the composition of the precursor feedstock during spraying, a fine composition gradient coating can be formed which is made up of the same small nanoparticle size particles of less than, 100 nm. Many combinations of materials can be co-deposited and by applying an external energy source either during the coating process or during post deposition, the resulting coating can be modified.
