Transmission electron micrographs of nanocavity-filled titanium oxide nanorods (bottom) and iron-doped titanate nanotubes (top). Both are being investigated as photocatalysts for reactions to produce hydrogen gas. The improved light-absorption of the nanocavity-filled nanorods also makes them ideal new materials for sunscreen.

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed new ways to make or modify nanorods and nanotubes of titanium oxide, a material used in a variety of industrial and medical applications. The methods and new titanium oxide materials may lead to improved catalysts for hydrogen production, more efficient solar cells, and more protective sunscreens.
