Carbon-coated iron catalyst structure could lead to more-active fuel cells

Fuel cells have long held promise as power sources, but low efficiency has created obstacles to realizing that promise. Researchers have identified the active form of an iron-containing catalyst for the trickiest part of the process: reducing oxygen gas, which has two oxygen atoms, so that it can break apart and combine with ionized hydrogen to make water.

Seeing polarons at a metal oxide surface

Polarons in metal oxides play a key role in processes such as catalysis, high temperature superconductivity, and dielectric breakdown in nanoscale electronics. For this reason, numerous studies have been conducted on technologically relevant oxide materials in which charge carriers are believed to be self-trapped, forming polarons.

Stretchable nano-devices towards smart contact lenses

A stretchable nano-scale device has been created to manipulate light. Using the technology, high-tech lenses could one day filter harmful optical radiation without interfering with vision - or in a more advanced version, transmit data and gather live vital information or even show information like a head-up display.
