Long-Sought Workaround to Helium Shortage?

Neutron Detection Method

12-Jun-2018

Doctors use X-rays to see inside people, and scientists use neutrons to peer inside advanced materials and devices such as fuel cells to better understand and improve them. But a critical shortage of a rare form of helium used for detecting neutrons—which are difficult to spot directly—threatens ...

3D X-rays measure particle movement inside lithium ion batteries

23-May-2018

Lithium ion batteries have come a long way since their introduction in the late 1990s. They're used in many everyday devices, such as laptop computers, mobile phones, and medical devices, as well as automotive and aerospace platforms, and others. However, lithium ion battery performance still can ...

Levitation yields better neutron-lifetime measurement

14-May-2018

Being repulsive can have its advantages. In the case of an experiment at Los Alamos National Laboratory's linear accelerator, a repulsive magnetic field and a clever detector system are allowing ultracold neutrons to be levitated so their actual lifetimes can be more accurately measured. For the ...

Elucidation of vibration energy of a single molecule in an external force field

14-May-2018

A molecule adsorbed on a surface (Figure 1A) vibrates on the surface (Figure 1B). The vibration energy is determined by the mass of the molecule and by the restoring forces exerted on the molecule. The restoring force originates from the interaction within the molecule and with the surface. By ...
