3D Printing of Glass Structures Using Laser Patterning of Precondensed, Liquid Silica and Organically Modified Silica Polymers

This technology allows for 3D printers to print optical structures that have a glassy texture. The technology takes liquid polymer silica and transforms it into the desired optical structure, with minimal shrinkage. Background: The 3D printer market has had an increasing demand and growth over the past few years. With the wide variety that the market...

Recrystallization of Ceramics

This technology is a recrystallization method of zirconium diboride (ZrB2) to change the ceramic material properties. The brittle nature of the ceramic material is transformed to be metal-like after the recrystallization process, which results in "strain-free" equiaxed grains. Background: Although ceramic materials are brittle with high...

Novel Method for Synthesis of Indoles

This invention describes a novel method of generating heterocyclic compounds via a 3+2 annulation. This method does not require expensive reagents and, in some instances, can be completed in a chiral manner. Background: Existing methods to synthesize heterocycles usually require multiple steps, metal catalysts, and/or relatively expensive reagents....
