Process Yields High-Energy-Density Plant-Based Transportation Fuel

A team of University of Wisconsin-Madison engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone - a biomass derivative - into the chemical equivalent of jet fuel. The process preserves about 95 percent of the energy from the original biomass.

Highly Absorbing, Flexible Solar Cells Created With Silicon Wire Arrays

Using arrays of long, thin silicon wires embedded in a polymer substrate, California Institute of Technology scientists have created a new type of flexible solar cell that enhances the absorption of sunlight and efficiently converts its photons into electrons. The solar cell uses a fraction of the expensive semiconductor materials required by conventional solar cells.

Turning Light Into an Electrical Current Using a Golden Nanoscale System

University of Pennsylvania material scientists have demonstrated the transduction of optical radiation to electrical current in a molecular circuit. The array of nano-sized molecules of gold respond to electromagnetic waves by creating surface plasmons that induce and project electrical current across molecules - similar to that of photovoltaic solar cells.
