Leslie Schoop, assistant professor of chemistry, called the work “a rediscovery of new physics in an old material."

Seeking to establish experimental proof for a highly contested topic – the role of vibrations in processes fundamental to solar energy conversion – researchers set out to map the progress of a photoinduced electron transfer (ET) reaction. 

Researchers in the Rabinowitz lab, collaborating with colleagues at the UPenn Perelman School of Medicine, completed the first comprehensive, quantitative mapping of human cardiac fuel use, reporting that the heart preferentially and voraciously consumes fatty acids.
