Iron-platinum catalyst keeps fuel cells clean, even in cold weather
Batteries are currently outpacing fuel cells in the technological race to power the electric vehicle. Lithium batteries keep getting cheaper, while fuel cells remain hampered by pricey, short-lived platinum catalysts. Researchers suggest that adding a bit more platinum—albeit in a novel form—could help fuel cell cars catch up.
Tiny scales for medical implants and flexible electronics
Scales are the material of choice for animals from pangolins to fish: They're customizable, water-friendly, strong but flexible, and easy to fix when damaged. Scientists would like to recreate this unique structure—they can imagine uses from medical implants to flexible electronics—but it's proved difficult using non-organic materials.
Carbon nanotubes for enhanced Li-S battery performance
Lithium-sulfur batteries are considered to be one of the most competitive candidates for "post-lithium" technology due to their advantageous cost and specific energy.
