Light work
Article Abstract:
Nanotubes that break apart water molecules to liberate hydrogen can now do so more efficiently and could soon use the optical spectrum of sunlight. Scientists have begun formulating titanium dioxide nanotubes that respond to visible light by adding carbon to titanium dioxide nanotubes to shift the wavelengths of light the tubes absorb to the visible portion of the spectrum which as much as doubles the efficiency under an artificial mixture of ultraviolet and visible light.

Chicken-wire electronics
Article Abstract:
The chicken-wire-like carbon structures have provided new devices and extraordinary physics for researchers. Nanotube researchers have developed a new way to make thin sheets of nanotubes that might be rapidly adaptable to commercial production, as they can be used as components of displays, solar cells, organic light-emitting diodes and artificial muscles.
