Lee Rannals for redOrbit.com - Your Universe Online Researchers at Stanford University and the Department of Energy's (DOE) SLAC National Accelerator Laboratory used an X-ray laser to get a glimpse of photosynthesis in action. Using the laser, they were able to look at the structure and chemical behavior of a natural catalyst involved in photosynthesis. "This method opens up the way to study changes going on in the catalytic cycle of the water oxidation in nature," Junko Yano, a chemist...

Hydrogen production by solar water splitting in photoelectrochemical cells (PEC) has long been considered the holy grail of sustainable energy research. Iron oxide is a promising electrode material. An international team of researchers led by Empa, the Swiss Federal Laboratories for Materials Science and Technology, have now gained in-depth insights into the electronic structure of an iron oxide electrode — while it was in operation. This opens up new possibilities for an affordable...

Algal protein gives boost to electrochemical water splitting Water splitting in photo-electrochemical cells to yield hydrogen is a promising way to sustainable fuels. A team of Swiss and US scientists now made major progress in developing highly efficient electrodes — made of an algal protein, thus mimicking a central step in natural photosynthesis. Photosynthesis is considered the «Holy Grail» in the field of sustainable energy generation because it directly converts...

Using advanced theoretical computations, a team of Kentucky scientists has derived a means to "tweak" an inexpensive semiconductor to function as photoelectrochemical catalyst. Scientists from the University of Kentucky and the University of Louisville have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight. The research, funded by the U.S. Department of Energy, was led by Professors Madhu Menon and R. Michael Sheetz at...

An international team, of scientists, led by a team at Monash University has found the key to the hydrogen economy could come from a very simple mineral, commonly seen as a black stain on rocks. Their findings, developed with the assistance of researchers at UC Davis in the USA and using the facilities at the Australian Synchrotron, was published in the journal Nature Chemistry yesterday 15 May 2011. Professor Leone Spiccia from the School of Chemistry at Monash University said the ultimate...

A report commissioned by the U.S. Department of Energy has concluded that a novel University of Colorado Boulder method of producing hydrogen fuel from sunlight is the only approach among eight competing technologies that is projected to meet future cost targets set by the federal agency. The process, which is being developed by Professor Alan Weimer's research team of CU-Boulder's chemical and biological engineering department, involves an array of mirrors to concentrate the sun's rays and...

KARLSRUHE, Germany, April 14, 2011 /PRNewswire/ -- The exploitation and utilization of new energy sources are considered to be among today's major challenges. Solar energy plays a central role, and its direct conversion into chemical energy, for example hydrogen generation by water splitting, is one of its interesting variants. Titanium oxide-based photocatalysis is the presently most efficient, yet little understood conversion process. In cooperation with colleagues from Germany and...

Scientists are making progress toward development of an "artificial leaf" that mimics a real leaf's chemical magic with photosynthesis "” but instead converts sunlight and water into a liquid fuel such as methanol for cars and trucks. That is among the conclusions in a newly-available report from top authorities on solar energy who met at the 1st Annual Chemical Sciences and Society Symposium. The gathering launched a new effort to initiate international cooperation and innovative...

Scientists at Israel's Weizmann Institute say they have developed a new water splitting technology that eliminates the need for a sacrificial chemical. Professor David Milstein and colleagues said their new technology achieved a bond generation between oxygen atoms and defined the mechanism by which it takes place. Discovery of an efficient artificial catalyst for the sunlight-driven splitting of water into oxygen and hydrogen is a major goal of renewable clean energy research, institute...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
