Decoding the role of water in gold nanocatalysis

Researchers have, for the first time, provided direct evidence of a water-mediated reaction mechanism for the catalytic oxidation of carbon monoxide. The work used gold nanoparticles and titanium dioxide as a catalyst to speed the process and determined that water serves as a co-catalyst for the reaction that transforms carbon monoxide into carbon dioxide.

Inhomogeneous surface plasmon polaritons

Scientists have discovered a new way to control light. Light can be guided along the surface of a metal via a surface plasmon polariton phenomenon. When light guided along the surface of one metal encounters a different metal surface, the new type of plasmon called an 'inhomogeneous surface plasmon polariton' results that has controlled confinement properties.
