Daniel George Nocera

Daniel George Nocera (born July 3, 1957 ) is an American chemist ( inorganic chemistry , photochemistry ). He is a professor at Harvard University and is known for research into the chemistry of the energy conversion of sunlight ( artificial photosynthesis ).

Life

Nocera graduated from Rutgers University with a bachelor's degree magna cum laude in 1979 and received his doctorate in 1984 under Harry B. Gray at Caltech (Spectroscopy, electrochemistry, and photochemistry of polynuclear metal-metal bonded complexes). From 1984 he was Assistant Professor and from 1990 Professor at Michigan State University (where he became Distinguished Professor) and from 1997 Professor at the Massachusetts Institute of Technology ( Henry Dreyfus Professor of Energy ) before becoming Patterson Rockwood Professor of Energy at Harvard in 2012 .

plant

He researches renewable energies and, in particular, methods of artificial photosynthesis (development of an artificial leaf ), that is, splitting water into hydrogen and oxygen for energy generation and energy storage (in the form of hydrogen). He and his group developed a method (RIPPLE) to arrange catalysts on a silicon chip.

As early as 2008, he developed a cheap water-splitting catalyst that disintegrated during the process, but renewed itself.

He researched energy conversion with multi-electron transfer and proton-coupled electron transfer. He applied the latter to the study of enzymes that transport radicals (for example ribonucleotide reductase ). He is also working on chemical sensors in the form of nanocrystals for cancer therapy, optical chemosensors in microfluidics and molecular tagging for measuring the speed of highly turbulent flows (Molecular Tagging Velocimetry, MTV).

In solid state physics he deals with the synthesis of frustrated spin systems. For example, in 2007 he and Young Lee suggested that a crystal structure (Kagome lattice) in the mineral Herbertsmithite is a quantum spin liquid, which was confirmed in 2012. In addition to ferro- and antiferromagnetism, quantum spin liquids represent a third magnetic phase in which the spins, unlike the other two phases, constantly fluctuate like the movements of molecules in a liquid, and their existence was originally suggested by Phil Anderson .

Honors

In 1990 he became a research fellow of the Alfred P. Sloan Foundation ( Sloan Research Fellow ). In 2012 he received the Remsen Award , in 2009 the American Chemical Society Award in Inorganic Chemistry , the Harrison Howe Award from ACS and also the Elizabeth Wood Award, the UN Science and Technology Award, the Burghausen Prize (2007), the Eni-Italgas Prize for Energy & the Environment and the I-APS Award in Photochemistry (2006). He is a member of the American Academy of Arts and Sciences , the National Academy of Sciences, and the Indian Academy of Sciences .

Others

In 2008 he founded the company Sun Catalyx. He also has a contract with the Indian Tata Group for industrial applications of his research.
