A new type of hybrid TiO2–Ag nanocluster (NC) photoelectrode exhibits wavelength-switchable photocurrent by tuning the light wavelength from ultraviolet (UV) to visible light. The combination of UV-active TiO2 and visible-light-active Ag NCs with photoelectrochemical behaviour leads to the unique switchable photocurrent in the system.

Organic Aerogels

ABSTRACTThe aqueous, sol-gel polymerization of melamine with formaldehyde, followed by supercritical extraction, leads to the formation of a new type of organic aerogel. Synthetic conditions (e.g. reaction time, pH) affect the density, transparency, and microstructure of the resultant aerogels. Unlike previous organic aerogels based upon resorcinol-formaldehyde, the melamine-formaldehyde aerogels are both colorless and transparent. Low densities (0.1–0.8 g/cc), high surface areas (∼1000 m2/g), and optical clarity are only a few of the promising characteristics of this new material.
