First direct look at how light excites electrons to kick off a chemical reaction

The first step in many light-driven chemical reactions, like the ones that power photosynthesis and human vision, is a shift in the arrangement of a molecule’s electrons as they absorb the light’s energy. Now scientists have directly observed this first step.

Energy researchers invent error-free catalysts

A team of researchers from the University of Minnesota, University of Massachusetts Amherst, University of Delaware, and University of California Santa Barbara have invented oscillating catalyst technology that can accelerate chemical reactions without errors. The groundbreaking technology can be incorporated into hundreds of industrial chemical technologies to reduce waste by thousands of tons each year while improving the performance and cost-efficiency of materials production.
