Physics - Electrons and Water Molecules Form a Pulsating Cluster

Electrons and Water Molecules Form a Pulsating Cluster March 3, 2021• Physics 14, s29 In water, single electrons can cluster with water molecules to form a quasiparticle that oscillates in size, a behavior that could influence the equilibration speed of chemical reactions in the system. M. Wörner/Max Born Institute M. Wörner/Max Born Institute × When a free electron in water interacts with neighboring water molecules, it can form a quasiparticle known as a “solvated” electron. How these solvated electrons behave provides fundamental insights for charge transport and chemical reactions. Now, Michael Wörner of the Max Born Institute in Germany and colleagues have observed solvated electrons in water inducing previously unseen terahertz-scale oscillations in the water’s polarization [1]. These oscillations may play an important role in how a chemical reaction approaches equilibrium.

Dr Michael Schneider receives European XFEL Young Scientist Award

Date Time Dr. Michael Schneider receives European XFEL Young Scientist Award The European XFEL Young Scientist Award recognizes outstanding contributions of young researchers in the early stages of their career to research at European XFEL. | Abb. Schneider, MBI Michael Schneider received the award for his important contributions in three distinct areas pertaining to diffraction experiments with soft x-rays at European XFEL. X-ray pulses delivered by x-ray free-electron lasers are typically focused to a few-micrometer size in order to achieve extreme x-ray intensities at the sample inside the scientific instrument. In his PhD work, Michael Schneider developed an approach to monitor the beam footprint on a solid transmission sample in a diffraction experiment. In essence, along with the diffraction pattern from a sample of interest captured on a 2D detector, his approach allows to simultaneously record an image of the spatial intensity distribution of an x-ray pulse on the sample

Extreme Ultra-violet laser pulses from white light

27 Jan 2021 Share: Researchers have found a way to effectively squeeze extreme-ultraviolet (XUV) wavelengths from white light. The team s new method compresses the spectral width of broadband visible white light combined with vacuum-ultraviolet (VUV) to generate narrowband laser pulses within the extreme-ultraviolet (XUV) range. Fig. 1: (a) A specific colour can be selected from a broadband light source using e.g. a prism or a grating. This comes, however, at the expense of losing most of the light. (b) By applying a nonlinear optical technique such as four-wave mixing in krypton, it is possible to generate a specific colour using all the available light at different colours.

High-flux table-top source for femtosecond hard X-ray pulses

(b) Copper tape target for X-ray. view more Credit: MBI Femtosecond hard X-ray pulses are an important tool for unraveling structure changes of condensed matter on atomic length and time scales. A novel laser-driven X-ray source provides femtosecond copper Kα pulses at a 1 kHz repetition rate with an unprecedented flux of some 10^12 X-ray photons per second. Elementary processes in physics, chemistry, and biology are connected with changes of the atomic or molecular structure on a femtosecond time scale (1 femtosecond (fs) = 10^-15 seconds). Ultrafast X-ray methods hold strong potential for following structure changes in space and time and generate movies of the motions of electrons, atoms and molecules. This perspective has resulted in a strong demand for femtosecond hard X-ray pul
