Title: Mary Ann Meador: Innovator in Optical Filters and Aerogels
Introduction
Mary Ann Meador is a distinguished inventor based in Strongsville, OH (US). She has made significant contributions to the field of optical filters and aerogels, holding a total of 4 patents. Her innovative work has implications for various scientific applications, particularly in astronomy and materials science.
Latest Patents
One of her latest patents is titled "Optical filter having polyimide aerogel substrate and infrared radiation scattering particles." This invention relates to broadband and tunable infrared (IR)-blocking optical filters for millimeter and sub-millimeter astronomy. The filters are composed of small diffusely scattered particles embedded in an aerogel substrate. The size of the scattering particles can be tuned to achieve variable cutoff frequencies. The aerogel scattering optical filters have ultra-low density and index of refraction, allowing for high transmission across a broad spectrum from zero frequency to above 1 THz, and as much as 10 THz.
Another notable patent is "Polymer cellulose nanocrystal composite aerogels." This invention involves composite materials that include cellulose nanocrystals incorporated into a polymer aerogel scaffold. The cellulose nanocrystals serve as a reinforcement agent, resulting in less dense aerogels that improve the tensile mechanical properties of aerogel films and reduce shrinkage upon thermal exposure. The properties of the composite aerogel can be tailored through surface modification of the cellulose nanocrystals and the backbone structure of the polymer.
