Measuring the mass of atoms through collisions with imaging electrons in an electron microscope

Imaging electrons of transmission electron microscopes can be used in research to drive and study the dynamics of atomic processes, especially in materials such as graphene (a one-atom-thick carbon layer). The measurement have resulted in a demand for an accurate theoretical description of the elastic collision process between the imaging electrons...

Noise-protected, tuneable, levitated pressure and force sensor

Very regular clocks are essential in our everyday lives. They enable us to navigate, from the marine chronometers used to determine longitude, to GPS. Stable clocks power the internet, defining the speed with which information can be sent and received.If your timepiece is very precise, it is easy to detect even small changes to its regularity. By measuring...
