Proton exchange membrane (PEM) fuel cells operate at relatively low temperatures and are composed of two electrodes and a conductive elecrolyte.

Ultrasonic spray pyrolysis (USP) is effective for preparing a wide array of materials and is scalable and continuous. Nanomaterials prepared by USP include nanoporous metal oxides and sulfides, nanocomposites, semiconductor quantum dots, and conductive metal inks.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
