Cell splits water via sunlight to produce hydrogen
05-02-2007 · EurekAlert!Engineers at Washington University in St. Louis have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst. The group is developing novel methodologies for synthesis of nanostructured films with superior opto-electronic properties.

- Learning how nature splits water
11-03-2006 · EurekAlert!
An international team led by scientists from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) pieced together high-resolution (approximately 0.15 Еngstrom) structures of a Mn4Ca cluster found in a photosynthetic protein complex. Their work could help researchers synthesize molecules that mimic this catalyst, which is a central focus in the push to develop clean energy technologies that rely on sunlight to split water and form hydrogen to feed fuel cells or other non-polluting power sources.

- New Developments in "Artificial Photosynthesis"
03-27-2007 · Brookhaven National Laboratory
Scientists at Brookhaven are trying to design catalysts inspired by photosynthesis, the natural process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a bio-inspired system that can produce fuels like methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy.

- Feeling the heat
01-10-2008 · EurekAlert!
Energy now lost as heat during the production of electricity could be harnessed through the use of silicon nanowires synthesized via a technique developed by researchers with the Lawrence Berkeley National Laboratory and the University of California at Berkeley. The far-ranging potential applications of this technology include DOE's hydrogen fuel cell-powered "Freedom CAR," and personal power-jackets that could use heat from the human body to recharge cell-phones and other electronic devices.

- Novel sugar-to-hydrogen technology promises transportation fuel independence
05-22-2007 · EurekAlert!
Researchers at Virginia Tech, Oak Ridge National Laboratory and the University of Georgia propose using polysaccharides, or sugary carbohydrates, from biomass to directly produce low-cost hydrogen for the new hydrogen economy. The vision is for the ingredients to be mixed in the fuel tank of your car, for instance, to power a fuel cell.

- Discovery of cardiac stem cells may advance regenerative heart therapy
11-22-2006 · EurekAlert!
An immediate early publication of the journal Cell, published by Cell Press, on Nov. 22, 2006, points to the possible existence of master cardiac stem cells with the capacity to produce all three major tissues of the mammalian heart. A companion Cell paper also published online reports the discovery of a second population of cardiac progenitors, which are capable of forming both cardiac muscle and the smooth muscle found in the heart's blood vessel walls.
