Using an X-ray free-electron laser and time-resolved X-ray solution scattering, researchers have watched, on a femtosecond timescale, the detailed steps that occur when covalent bonds form in solution ...

For the first time, researchers have captured the ephemeral electron movements in a transient state of a chemical reaction using ultrafast, tabletop X-ray spectroscopy. The researchers used ...

In a recent study published in Physical Review Letters, an international team of researchers examined how ions interact with graphene and molybdenum disulphide (MoS 2) on timescales of one femtosecond ...

Imagine being able to see every bit of a chemical reaction as it happens. To observe reactants form fleeting intermediates that seamlessly transform into products. Or to watch a movie of a protein as ...

X ray spectroscopy is a widely used method to characterize a compound based on its characteristic X ray emission spectrum 1. When energy is supplied to an atom, the electrons in the atom absorbs the ...

Over billions of years of evolution, many organisms in nature have exhibited unique surface wettability. For example, lotus leaves have the self-cleaning function. Water striders can walk on water.

The ephemeral electron movements in a transient state of a reaction important in biochemical and optoelectronic processes have been captured and, for the first time, directly characterized using ...
