Checking out iron under pressure

Iron is the most stable and heaviest chemical element produced by nucleosynthesis in stars, making it the most abundant heavy element in the universe and in the interiors of Earth and other rocky planets.

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. ...
