Comparing photosynthetic and photovoltaic efficiencies and recognizing the potential for improvementMay 1, 2011

Comparing photosynthetic and photovoltaic efficiencies is not a simple issue. Both harvest the energy in sunlight, operate in distinctly different ways and produce different types of products: biomass or chemical fuels in the case of natural photosynthesis and non-stored electrical current in the case of photovoltaics. To find common ground for evaluating energy-conversion efficiency, a group of researchers lead by Robert Blankenship of Washington University in St.

GM, Argonne sign licensing deal for advanced battery chemistryJanuary 6, 2011

General Motors Co. and Argonne National Laboratory announced today they have reached a worldwide licensing agreement to use Argonne's patented composite cathode material to make advanced lithium-ion batteries that last longer between charges and can charge at higher voltages.

Spin signatures of photogenerated radical anionsOctober 1, 2010

Photovoltaic (PV) cells are the most promising man-made devices for direct solar energy utilization. In analogy with natural photosynthesis, the key steps in PV solar energy conversion are the generation, separation and extraction of charges.

What happens to organic molecules on Mars?August 1, 2010

The ongoing search for evidence of past or present life on Mars includes efforts to identify organic compounds and biomarkers, such as proteins in Martian soil, but their absence to date remains a mystery.

DOE awards Argonne projects 200 million hours of supercomputer timeJuly 28, 2010

Five researchers at Argonne National Laboratory will lead projects that have been awarded almost 200 million processor-hours of computing time at Argonne’s Leadership Computing Facility.

Argonne scientist receives Humboldt Research AwardJune 1, 2010

Julius Jellinek of Argonne National Laboratory has been elected a recipient of the prestigious Humboldt Research Award, known also as the Humboldt Prize, by the Alexander von Humboldt Foundation in Germany for his extensive groundbreaking work in physics and chemistry of finite-size systems.
