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 ultrafast X-ray spectroscopy at the Department of Energy's Lawrence Berkeley National Laboratory (Berkele more

Femtosecond X-ray spectroscopy
A new record at BESSY II: ten million ions in an ion trap cooled for the first time to 7.4 K
Previously it was only possible to cool down about one thousand ions to 7.5 K using buffer gas. However, a thousand ions are not nearly enough for spectroscopic analyses. The ion trap with this new method provides a new opportunity to use cryogenic X-ray spectroscopy to study the magnetism and groun more
How to measure oxygen coefficient in complex oxides
Scientists of the Faculty of Chemistry of the Lomonosov Moscow State University under the leadership of Prof. Yury Teterin and in cooperation with Russian and British colleagues have developed a technique, which provides an opportunity of quantitative evaluation of oxygen coefficient of uranium in c more
