In Situ X-Ray Scattering Helps Optimize Printed Solar Cells Print
Wednesday, 25 February 2015 00:00

Printable plastic solar cells are a potential source of inexpensive renewable energy, but the transition from lab to factory results in decreased efficiency. Now, for the first time, a miniature solar-cell printer installed in a beamline allows researchers to use x-ray diffraction and scattering to figure out why.

From CO2 to Methanol via Novel Nanocatalysts Print
Wednesday, 03 December 2014 00:00

Researchers have found novel nanocatalysts that lower the barrier to converting carbon dioxide—an abundant greenhouse gas—into methanol—a key commodity used to produce numerous industrial chemicals and fuels. In one case, it worked almost 90 times faster than catalysts commonly used for this reaction today.
