"Model-free pattern separation of two-color ultrafast X-ray diffraction"On the Trail of Dissolution: Only 30 Water Molecules Separate Salt
How much water does a salt molecule really need to dissolve? An international research team, including researchers from the University of Kassel, has now visualized the process at the atomic level for the first time. The study shows that the particles only separate permanently once there are about 30 water molecules. These findings provide important fundamental knowledge for Chemistry, Biology, and atmospheric research.Detecting Nanoparticles Using X-Ray Films Composed of Two Images
A long-standing dream in research using ultrashort X-ray pulses has been to observe changes in nanoparticles or biomolecules on their natural timescale. Experimentally, this can be achieved by capturing two snapshots of the same nano-object just a few femtoseconds (one millionth of a billionth of a second) apart. A new technical feature of the European XFEL has now made a major step toward realizing this dream. The University of Kassel contributed to this achievement.New publication in Physical Chemistry Chemical Physics
