Application

Silica dioxide electrospun milled nanofibers can absorb significantly more water than commercially aailable silicagel of the same mesoporous character. Applications include adsorbent of water and other polar sorbents, catalyst carrier, filtration, separation, li-ion battery separators, and sensors.

PGM and PGM-free Catalysts for Polymer Electrolyte Membrane Fuel Cells

In this review, we highlight the recent progress in both PGM and PGM-free ORR catalysts for PEMFC applications. In addition, the remaining challenges in ORR catalyst development that meet the targets of PEMFC applications beyond the preliminary half-cell test are also discussed.

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