Like many other labs, Graham Fleming’s group is focusing on interdisciplinary techniques to make new discoveries and explore the mysteries of fundamental processes. Chemistry graduate student Kaydren Orcutt highlights how researchers can combine physics and biology, generating single photons in a bid to unentangle the mysteries of photosynthesis.

Birgitta Whaley

Birgitta Whaley, a UC Berkeley professor of chemistry and co-director of the Berkeley Quantum Information and Computation Center, has been appointed to the U.S. President’s Council of Advisors on Science and Technology (PCAST), the White House announced on Tuesday, Oct. 22. Whaley, who is also a faculty scientist at Lawrence Berkeley National Laboratory, was among seven new advisers, the first PCAST members appointed by President Donald Trump since his inauguration three years ago. Upon signing an executive order this morning launching PCAST, President Trump indicated that he would appoint another nine advisers, for a total of 16.

Meet our faculty: Martin Head-Gordon

Martin Head-Gordon

Learn about Martin Head-Gordon, a theoretical chemist at the University of California, Berkeley and Lawrence Berkeley National Laboratory, and a recently elected member of the National Academy of Sciences. He develops electronic structure theory to permit improved calculations of molecules, including the strength of chemical bonds. To better understand how and why bonds form, he also works on energy decomposition analysis (EDA), which gives the value of physically different contributions to chemical bonds.

Quantum dots are just as awesome as we'd hoped

Quantum dots—tiny, easy-to-produce particles—may soon take the place of more expensive single crystal semiconductors in advanced electronics found in solar panels, camera sensors, and medical imaging tools.

Scientists measure near-perfect performance in low-cost semiconductors

High-quality bespoke nanocrystalsTiny, easy-to-produce particles, called quantum dots, may soon take the place of more expensive single crystal semiconductors in advanced electronics found in solar panels, camera sensors and medical imaging tools. Although quantum dots have begun to break into the consumer market – in the form of quantum dot TVs – they have been hampered by long-standing uncertainties about their quality. Now, a new measurement technique developed by researchers at Stanford University and UC Berkeley may finally dissolve those doubts.
