A virtual wall for oily liquids

Researchers have developed a technique to form a virtual wall for oily liquids that will help confine them to a certain area, aiding researchers who are studying these complex molecules. This development will have future implications in the guided delivery of oil and effective blockage of oil spreading.

Intense two-color double X-ray laser pulses: a powerful tool to study ultrafast processes

A team working at the SACLA X-ray Free-Electron Laser (XFEL) in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions.
