Researchers have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy.
Technology has been developed for a catheter-based device that would provide forward-looking, real-time, three-dimensional imaging from inside the heart and blood vessels.
Using electrons more like photons could provide the foundation for a new type of electronic device that would capitalize on the ability of graphene to carry electrons with almost no resistance.
