(Phys.org)—From petroleum refining to food processing, the vast majority of commercial chemical applications involve catalysts to control the rate of chemical reactions. Anything that can increase the efficiency of catalysts ...
Specially shaped laser pulses can be used to change the state of electrons in a molecule. This process only takes several attoseconds—but it can initiate another, much slower process: The splitting of the molecule into ...
