Tiny double accelerator recycles energy

A team of DESY scientists has built a miniature double particle accelerator that can recycle some of the laser energy fed into the system to boost the energy of the accelerated electrons a second time. The device uses narrowband ...

Scientists reveal infrared spectroscopy of neutral water dimer

A research team led by Profs. Jiang Ling, Yang Xueming and Zhang Donghui from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences, in collaboration with Prof. Li Jun from Tsinghua University, ...

Sneaking up on tiny crystals with electron diffraction

Understanding the structure of proteins, the building blocks of life, is essential to obtain insight into their biological function. Due to their minute size and extreme fragility, these structures are enormously difficult ...

When plasmons reach atomic flatland

Researchers from the MPSD and the Lawrence Berkeley National Laboratory (LBNL) in the United States have discovered a significant new fundamental kind of quantum electronic oscillation, or plasmon, in atomically thin materials. ...

Temporally shaping the electric field of an attosecond pulse

Chemical reactions are determined at their most fundamental level by their respective electronic structure and dynamics. Steered by a stimulus such as light irradiation, electrons rearrange themselves in liquids or solids. ...

Photosynthesis seen in a new light by rapid X-ray pulses

The ability to transform sunlight into energy is one of Nature's more remarkable feats. Scientists understand the basic process of photosynthesis, but many crucial details remain elusive, occurring at dimensions and fleeting ...

Happy hour for time-resolved crystallography

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg ...
