Elizabeth Gardner, Purdue University Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Purdue University physicists are part of an international group using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun’s energy into carbohydrates used to power cellular processes. “The proteins we study...

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...

New Insights Could Lead To Better Catalysts For Water Splitting

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...

Inexpensive hydrogen for automotive or jet fuel may be possible by mimicking photosynthesis, according to a Penn State materials chemist, but a number of problems need to be solved first. "We are focused on the hardest way to make fuel," said Thomas Mallouk, Evan Pugh Professor of Materials Chemistry and Physics. "We are creating an artificial system that mimics photosynthesis, but it will be practical only when it is as cheap as gasoline or jet fuel." Splitting water into hydrogen and oxygen...

In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular "dimmer switch" that helps control the flow of solar energy moving through the system of light harvesting proteins. This discovery holds important implications for the future design of artificial photosynthesis systems that could provide the world with a sustainable and secure source of...
