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 ...

One catalyst supplies electrons, other one controls position of raw material. Reactions are powered by visible light, not UV. Technique could allow creation of novel molecules for pharmaceuticals.

Small molecules with a carbon-carbon double bond—alkenes—are starting points for chemicals in products such as paints and flavorings. But many ways to modify alkenes are energy intensive or depend on ...

Most chemical reactions take place within just a few picoseconds – that is, 10-12 seconds. Several techniques are already available for studying reactions between gases or solutions, but the dynamics ...

On the move: time sequence of the electron distribution of the molecule 1,3-cyclohexadiene after it is excited by a light pulse. (Courtesy: SLAC) Scientists in the US and UK are the first to observe ...

Harvard researchers uncovered the surprising role of light in ultra-cold chemical reactions, according to an article published last month in the scientific journal Nature Physics. Chemistry and ...

Waves of electricity or chemicals ripple through living tissues in many processes, including heart-muscle contractions, nerve signaling, and cell metabolism. To learn how those waves form and ...

Chemical manufacturing is an energy-intensive industry; a team of chemists is designing a technique that could power the necessary reactions with sunlight or LEDs. Read from CU expert Arindam Sau and ...
