| Application: | (3-Glycidyloxypropyl)trie • Polymer nanocomposite membranes for direct methanol fuel cells (DMFCs). • Azido terminated poly(ethylene glycol) silane that can be self-assembled on a metal-oxide surface to facilitate the orthogonal biofunctionalization. • Epoxy functionalized silsesquioxane nanoparticles (SQ-NPs). • Epoxy-functionalized mesoporous cellular foams (G-MCFs) as the support for the immobilization of penicillin G acylase (PGA). GPTES can also be used as a precursor to prepare water-repellent, self-cleaning coatings. |
