About
Doug Loy is a professor at the University of Arizona in the Department of Chemistry and Biochemistry. He holds a Master of Science degree from Northern Arizona University and a Ph.D. from the University of California, Irvine. His professional experience includes technical staff positions at Sandia National Labs from 1991 to 2003 and at Los Alamos National Labs from 2003 to 2005. He also served as an adjunct professor at the University of New Mexico from 2001 to 2005. His research focuses on energy science, instrument development, materials and polymer chemistry, surface and solid state chemistry, and synthesis and synthetic methods development. A significant area of his research involves fuel cell electrolyte membranes, where he aims to develop cost-effective, easily processed, and chemically stable proton-conducting membranes with high thermal stability and tailorable gas permeabilities. Notably, he and his colleagues at Sandia National Labs have developed sulfonated polyarylenes as polymeric electrolytes, which have demonstrated excellent proton conductivity, thermal stability, mechanical properties, and chemical stability. Fuel cells built with these membranes have outperformed those using commercially available membranes, highlighting his contributions to advancing fuel cell technology.

with olefinic alcohols and dynamic covalent polymerizations with dienes to prepare sulfur polyols and terpolyols that were used in polymerizations with aromatic diisocyanates and short chain diols. Using these methods, a new class of high molecular weight, soluble block copolymer polyurethanes were prepared as confirmed by Size Exclusion Chromatography, NMR spectroscopy, thermal analysis, and microscopic imaging. These sulfur-based polyurethanes were readily solution processed into large area fr…
Three-dimensional printing of glass micro-optics
Optica · 2021 · 89 citations
To meet the increasing needs of high-precision glass micro-optics and address the major limitations of current three-dimensional (3D) printing optics, we have developed a liquid, solvent-free, silica precursor and two-photon 3D printing process. The printed optical elements can be fully converted to transparent inorganic glass at temperatures as low as 600 C with a shrinkage rate of 17%. We have demonstrated the whole process, from material development, printing, and performance evaluation of th…

articleOpen accessTo address the major challenges to obtain high spatial resolution in snapshot hyperspectral imaging, 3D printed glass lightguide array has been developed to sample the intermediate image in high spatial resolution and redistribute the pixels in the output end to achieve high spectral resolution. Curved 3D printed lightguide array can significantly simplify the snapshot hyperspectral imaging system, achieve better imaging performance, and reduce the system complexity and cost. We have developed t…
