New Catalyst Could Speed Up Fuel Cells
September 15, 2016 | Leave a Comment
University of Illinois at Urbana-Champaign researchers have identified the active form of an iron-containing catalyst for reducing oxygen gas, the element in a fuel cell that slows the process. Fuel cells have long held promise as power sources, but low efficiency from oxygen presence creates an obstacle to realizing the potential. The finding could help […]

Fish Scales Used to Build Energy Harvester
September 8, 2016 | Leave a Comment
Researchers in India at Jadavpur University in Koltata explored and found a way to recycle fish byproducts into an energy harvester for self-powered electronics. The basic premise behind the researchers’ work is simple: Fish scales contain collagen fibers that possess a piezoelectric property, which means that an electric charge is generated in response to applying […]
