US Patent 7306822 - Ceramic nanopowder for forming passive electronic devices

http://www.freepatentsonline.com/7306822.html

This patent from Nanoproducts Corp. teaches forming passive electronics components such as capacitors, resistors, or inductors from ceramic nanoparticle films. Claim 1 reads:

1. A method for manufacturing a product comprising one or more passive electronic components, wherein the method comprises: providing ceramic nanopowders; suspending the nanopowders in a solvent thereby preparing a nanopowder dispersion or paste; forming a layer from the nanopowder dispersion or paste such that the average grain size of the nanopowder in the layer is equal to or less than 100 nanometers; and wherein the layer provides at least one passive electronic device function selected from the group consisting of capacitor, resistor, varistor and inductor; and processing the layer into one or more passive electronic components.

US Patent 7178747 -Nanoparticle aspect ratio modification

http://www.freepatentsonline.com/7178747.pdf

While the mechanical, electrical, and optical benefits of various nanoparticles are favorable, there are still several issues restricting broad usage of nanoparticles such as nanoparticle clumping, undesired gas absorption, and variability on nanoparticle types produced. These problems necessitate post-processing of the nanoparticles and this patent from Nanoproducts Corporation teaches such post-process refining methods. Claim 1 reads:

1. A method for modifying the shape of nanomaterials comprising: providing nanomaterials of a first aspect ratio; mixing the nanomaterials with a catalyst; processing the mixture at a temperature greater than 300 K; and collecting nanomaterials with an aspect ratio different than the first aspect ratio.
