Small optical force can budge nanoscale objects.
With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported.
Spectral phase conjugation via temporal imaging
Cornell Group, led by CNS Director Alex Gaeta, experimentally demonstrate wavelength-preserving spectral phase conjugation for compensating chromatic dispersion and self-phase modulation in optical fibers.
A paper by recently-graduated C&CB graduate student Michael Jaquith and Associate Professor, and CNS Researcher, John Marohn is featured on the front cover of the 14 September 2009 edition of the Journal of Materials Chemistry.

Carbon nanotube 'ink' may lead to thinner, lighter transistors and solar cells
Using a simple chemical process, scientists at Cornell and DuPont have invented a method of preparing carbon nanotubes for suspension in a semiconducting "ink," which can then be printed into such thin, flexible electronics as transistors and photovoltaic materials.
Electron Injection from Colloidal PbS Quantum Dots into Titanium Dioxide Nanoparticles
CNS researchers recently published work that includes demonstration of a nanocrystal-based solar cell.
