Ambient Dried Aerogels based on Alkyl Sulfide Bridged Polysilsesquioxanes
Aerogel is a low-density solid material that is produced by removing the liquid component from a conventional gel. Ambient dried aerogels utilize calculated levels of temperature and pressure using certain chemicals to remove the liquids from the aerogel. This technology is a method of preparation of low density, porous aerogels without the use of supercritical...

Reworkable UV Curable Thermosets Based on 7-Glycidyloxycoumarin Dimers
This invention focuses on epoxy thermosets that are developed by UV curing epoxy monomers with coumarin dimer. Background: This invention focuses on a new process for epoxy thermosets to be prepared--curing the epoxy monomers with coumarin dimer bridging groups between epoxide groups that are cured with commercial hardeners. Using the coumarin dimer...

Reworkable UV Curable Thermosets based on 7-Glycidyloxycoumarin
This invention describes a reversible thermoset that is cured by a particular set of ultraviolet waves and degraded by a different set of ultraviolet waves. The resin's ability to be re-used makes it a dynamic choice for adhesive and structural needs. Background: Epoxy, a thermosetting resin, is an adhesive compound that is hardened by a variety...

Reactive, Fluorescent Epoxy Monomers for Making Epoxy Thermosets Visible Under Ultraviolet Light
This technology allows for the easy identification of epoxy repairs using ultraviolet (UV) light. A fluorescent dye is covalently bonded to the epoxy group molecule, preventing it from leaching out of the cured adhesive. This dye, which emits a bright fluorescence under UV light, does not reduce the adhesive strength of the epoxy and will not lose its...
