A perspective article published last month by University of California, Riverside chemists in the Journal of Physical Chemistry Letters was selected as an Editors Choice—an honor only a handful of research papers receive.

Laser-like Beams That Use 250x Less Power
2014-06-06 03:56:27

With precarious particles called polaritons that straddle the worlds of light and matter, University of Michigan researchers have demonstrated a new, practical and potentially more efficient way to make a coherent laser-like beam.

JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet.

Study Could Lead To Paradigm Shift In Organic Solar Cell Research
2013-11-20 09:56:25

Organic solar cells have long been touted as lightweight, low-cost alternatives to rigid solar panels made of silicon.

Harnessing Power By Funneling Solar Energy
2012-11-26 12:53:51

MIT engineers have worked out a computational model which shows how solar energy can be more or less funneled before it’s captured, ensuring an efficient and effective solar energy capturing mechanism.

Organic Solar Cells One Step Closer To Success
2012-06-15 13:24:53

Organic solar cells have long been a promising alternative to conventional solar cells, but their low efficiency, low stability, and low strength have kept them from widespread commercial use.

2012-05-24 21:01:08

Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave.

Single Nanomaterial Yields Many Laser Colors
2012-04-30 07:46:35

Engineers at Brown University and QD Vision Inc. have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays.

2012-03-30 07:50:23

Physicists at the University of California, San Diego have discovered patterns which underlie the properties of a new state of matter.
