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...

Stable isotope labelled amino acids from cell walls/cell membranes

Mass spectrometry is becoming a cutting edge technology in the fields of clinical diagnostics and personalized medicine. A key application is the quantification and/or assessment of fold changes of molecules derived from primary and secondary metabolism. Samples derived from human origin contain a wide variety of metabolites at a wide range of concentrations,...

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...

Laser Eye

Lasers produce a concentrated beam of light which can cause permanent eye damage if viewed directly. Standard protective goggles block out a narrow frequency range which must be matched to the laser in use. However if the laser uses multiple wavelengths, or if these occur in the visible spectrum then the user may not even be able to see what they are...
