Scientists led by Prof Zhiwei Huang at National University of Singapore have developed a novel time-of-flight resolved Bessel light bullet-enabled stimulated Raman scattering microscopy for deeper tissue 3D chemical imaging with high resolution.

A Swift Kick to Initiate Electronic Motion in Molecules

December 7, 2020 sarah JonasFeature

Researchers have observed the production of electronic excitations near a single atom in a molecule. This is caused by impulsive stimulated X-ray Raman scattering of X-ray pulses that last less than a femtosecond. The combination of X-ray Raman scattering and the ability produce sub-femtosecond X-ray pulses allows scientists to view motion in molecules at atom-scale resolution and helps them understand chemical reactions involving light.
