Title: Innovations of David A. Nelson
Introduction
David A. Nelson is a notable inventor based in Richland, WA (US). He has made significant contributions to the field of materials science and engineering, holding a total of 5 patents. His work focuses on innovative solutions for chemical absorption and water separation technologies.
Latest Patents
One of his latest patents is for a "Photopatternable sorbent and functionalized films." This invention involves a composition that includes a polymer, a crosslinker, and a photo-activatable catalyst placed on a substrate. The composition is exposed to a predetermined pattern of light, which leaves an unexposed region. The light causes the polymer to become crosslinked by hydrosilylation. A solvent is then used to remove the unexposed composition from the substrate, resulting in a sorbent polymer film that can absorb specific chemical species when exposed.
Another significant patent is the "Method and apparatus for tritiated water separation." This invention presents a membrane method and apparatus designed to separate isotopic water constituents from light water. The method involves using a supported membrane made of aromatic polyphosphazene and pressurizing the water on one side of the membrane. This process forces the light water through the membrane while retaining the isotopic water constituents.
