Another Milestone in Hybrid Artificial Photosynthesis

Berkeley Lab researchers using a bioinorganic hybrid approach to artificial photosynthesis have combined semiconducting nanowires with select microbes to create a system that produces renewable molecular hydrogen and uses it to synthesize carbon dioxide into methane, the primary constituent of natural gas.

Orange is the New Red

Berkeley Lab researchers discovered that a photoprotective mechanism in cyanobacteria is triggered by an unprecedented, large-scale movement from one location to another of the carotenoid pigment within the Orange Carotenoid Protein.

CLAIRE Brings Electron Microscopy to Soft Materials

Berkeley Lab researchers, working at the Molecular Foundry, have invented a technique called “CLAIRE” that extends the incredible resolution of electron microscopy to the non-invasive nanoscale imaging of soft matter, including biomolecules, liquids, polymers, gels and foams.

Major Advance in Artificial Photosynthesis Poses Win/Win for the Environment

By combining biocompatible light-capturing nanowire arrays with select bacterial populations, a potentially game-changing new artificial photosynthesis system offers a win/win situation for the environment: solar-powered green chemistry using sequestered carbon dioxide.

Two Berkeley Lab Scientists Named AAAS Fellows

Two Berkeley Lab scientists, climate scientist William Collins and chemist Heinz Frei, have been named Fellows of the American Association for the Advancement of Science (AAAS) for 2014.

On the Road to Artificial Photosynthesis

New experimental results have revealed the critical influence of the electronic and geometric effects in the carbon dioxide reduction reaction.

Postcards from the Photosynthetic Edge

Using the world’s most powerful x-ray laser, an international collaboration led by Berkeley Lab researchers took femtosecond “snapshots” of water oxidation in photosystem II, the only known biological system able to harness sunlight for splitting the water molecule. The results should help advance the development of artificial photosynthesis for clean, green and renewable energy.

Dynamic Spectroscopy Duo

Berkeley Lab researchers have developed a new technique called two-dimensional electronic-vibrational spectroscopy that can be used to study the interplay between electrons and atomic nuclei during a photochemical reaction. Photochemical reactions are critical to a wide range of natural and technological phenomena, including photosynthesis, vision, nanomaterials and solar energy.

Promising News for Solar Fuels from Berkeley Lab Researchers at JCAP

A JCAP study shows that nearly 90-percent of the electrons generated by a semiconductor/cobaloxime hybrid catalyst designed to store solar energy in hydrogen are being stored in their intended target molecules.

Every Step You Take: Berkeley Lab Researchers Identify Key Intermediate Steps in Artificial Photosynthesis Reaction

The first direct, temporally resolved observations of intermediate steps in water oxidation using cobalt oxide, an Earth-abundant solid catalyst, revealed kinetic bottlenecks whose elimination would help boost the efficiency of artificial photosynthesis systems.
