Researchers Develop Novel Method To Observe Mysterious Photosynthesis Process
2014-07-10 13:21:26

Brett Smith for redOrbit.com - Your Universe Online In the pursuit of a renewable energy source, scientists have been trying to understand the exact mechanism behind photosynthesis, and now a large team of scientists has successfully captured the detailed “snapshots” of the process using a powerful laser, according to a report in Nature Communications. “An effective method of solar-based water-splitting is essential for artificial photosynthesis to succeed but developing such a...

Promising News For Solar Fuels from Berkeley Lab Researchers
2014-03-07 15:04:01

Berkeley Lab There’s promising news from the front on efforts to produce  fuels through artificial photosynthesis. A new study by Berkeley Lab researchers at the Joint Center for Artificial Photosynthesis (JCAP) shows that nearly 90-percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules. Gary Moore, a chemist and principal investigator with Berkeley Lab’s Physical Biosciences Division, led...

Researchers Identify Key Intermediate Steps In Artificial Photosynthesis Reaction

Lynn Yarris, Berkeley Lab Artificial photosynthesis, in which we emulate the process used by nature to capture energy from the sun and convert it into electrochemical energy, is expected to be a major asset in any sustainable energy portfolio for the future. Artificial photosynthesis offers the promise of producing liquid fuels that are renewable and can be used without exacerbating global climate change. A key to realizing commercial-scale artificial photosynthesis technology is the...

Artificial Leaf Jumps Developmental Hurdle
2014-02-19 13:11:38

Arizona State University In a recent early online edition of Nature Chemistry, ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf. Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel – the Energy Frontier Research Center, funded by the Department of Energy, in the Department of Chemistry and...

Method Developed To Make Hydrogen Fuel From Sunlight
2013-08-29 15:41:47

Lawrence Berkeley National Laboratory Berkeley Lab Researchers at Joint Center for Artificial Photosynthesis Make Unique Semiconductor/Catalyst Construct In the search for clean, green sustainable energy sources to meet human needs for generations to come, perhaps no technology matches the ultimate potential of artificial photosynthesis. Bionic leaves that could produce energy-dense fuels from nothing more than sunlight, water and atmosphere-warming carbon dioxide, with no byproducts...

Manganese Oxidation Played Key Role In Formation Of Oxygen On Earth
2013-06-27 07:25:47

April Flowers for redOrbit.com - Your Universe Online Oxygen is a necessary component for the survival of most terrestrial life on Earth. The planet´s atmosphere, however, did not always contain this life-sustaining substance. How and when oxygenic photosynthesis — the process responsible for producing oxygen on Earth through the splitting of water molecules — first began has been considered one of the great science mysteries of our planet. A new study, led by...

Details Described For Low-Cost, Biomass-Derived Catalyst For Hydrogen Production
2013-04-24 14:22:38

Brookhaven National Laboratory Promising results are a step toward a range of renewable energy strategies fueled by Nature In a paper to be published in an upcoming issue of Energy & Environmental Science (now available online), researchers at the U.S. Department of Energy's Brookhaven National Laboratory describe details of a low-cost, stable, effective catalyst that could replace costly platinum in the production of hydrogen. The catalyst, made from renewable soybeans and abundant...

Another innovative feature has been added to the world's first practical "artificial leaf," making the device even more suitable for providing people in developing countries and remote areas with electricity, scientists reported here today. It gives the leaf the ability to self-heal damage that occurs during production of energy. Daniel G. Nocera, Ph.D., described the advance during the "Kavli Foundation Innovations in Chemistry Lecture" at the 245th National Meeting & Exposition of...

New Insights Could Lead To Better Catalysts For Water Splitting
2013-03-29 10:47:24

California Institute of Technology Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory believe they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe. The finding suggests a new way of approaching the design of catalysts that drive the water-splitting reactions of artificial photosynthesis. "If we want to...

Making Electricity With Artificial Leaves Made From Crystalline Silicon
2013-03-05 20:11:32

Lee Rannals for redOrbit.com — Your Universe Online Researchers writing in the Proceedings of the National Academy of Sciences claim they have developed a solar-to-fuel roadmap for crystalline silicon, opening up a potential future system that efficiently harvests sunlight to make storable fuel. A new analysis helps lay out the roadmap for researchers to improve the efficiency of an "artificial leaf," which is a concept of using a silicon solar cell to harness sunlight the way...
