In experiments with the lab’s ultrafast "electron camera," laser light hitting a material is almost completely converted into nuclear vibrations, which are key to switching a material’s properties on and off for future electronics and other applications.
Research with SLAC’s X-ray laser simulates what happens when a meteor hits Earth’s crust. The results suggest that scientists studying impact sites have been overestimating the sizes of the meteors that made them.
This novel method could shrink the equipment needed to make laser pulses billionths of a billionth of a second long for studying ultra-speedy electron movements in solids, chemical reactions and future electronics.
With SLAC’s X-ray laser, a research team captured ultrafast changes in fluorescent proteins between “dark” and “light” states. The insights allowed the scientists to design improved markers for biological imaging.
Following the 2017 American Physical Society (APS) general election, Philip Bucksbaum will be vice president of APS in 2018 – an election that places him in the presidential line. He will become president-elect in 2019 and president in 2020.
The research team was able to watch energy from light flow through atomic ripples in a molecule. Such insights may provide new ways to develop a class of materials that improve efficiency and reduce the size of applications like solar cells and memory storage devices.
