BES Highlights

New capabilities at x-ray free-electron lasers (XFELs), such as the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory,
The transition state is where reactants become products in a chemical reaction. Defined as the highest energy point on the minimum energy path
Second-generation bioethanol is derived from cellulose-based feedstocks. Production of such bioethanol is expected to grow significantly worldwide
Enzymes that contain metal ions—that is, metalloenzymes—possess the reactivity of a transition metal center and the molecular evolution
For semi-rigid molecules at low energies, the well-established normal mode approximation gives a basic understanding of molecular vibrations and
