Researchers Capture Elusive Missing Step in Photosynthesis

May 5, 2023

After decades of effort, scientists have revealed atomic-scale details of the water splitting step of photosynthesis, the chemical process that generates the air we breathe. The latest work adds to our understanding of photosynthesis and will aid the development of fully renewable alternative energy sources.

New Device Advances Commercial Viability of Solar Fuels

December 17, 2021

A research team led by Francesca Toma, a staff scientist in the Liquid Sunlight Alliance (LiSA) and Chemical Sciences Division (CSD), has developed an artificial photosynthesis device with remarkable stability and longevity as it converts sunlight and carbon dioxide into ethylene and hydrogen—two promising sources of renewable fuels. The team used electron microscopy at the Molecular Foundry and ambient pressure X-ray photoelectron spectroscopy (APXPS) at the Advanced Light Source  to reveal how the device degrades with use, then demonstrate how to mitigate those processes.

Chloro-phylling in the Answers to Big Questions

December 1, 2021

A team of scientists, including many in the Molecular Biophysics and Integrated Bioimaging Division, uncovered new details about the reaction that powers photosynthesis. Understanding this reaction could lead to world-changing advances in technology, medicine, or energy––and also gives insight into how the enzyme photosystem II produces the oxygen we breathe. Their latest work was recently published in Nature Communications and two of the authors, Vittal Yachandra and Philipp Simon, spoke with Strategic Communications about that, shooting stuff with lasers, and why they chose this field of research.
