Neutrinos weighed by the world's most precise scale

12-Jun-2018 - The Karlsruhe Tritium Neutrino Experiment KATRIN now starts to weigh the mass of neutrinos. Following the electrostatic spectrometer and the detector unit, the tritium source was installed as the last of the large components of KATRIN. The ambitious and highly motivated team of physicists, ...

“Multi-spectra glasses” for scanning electron microscopy

30-Sep-2014 - The scanning electron microscope is not only used for precisely surveying the surface topology of samples, but also for determining their chemical compositions. This is done by exciting the atoms to fluoresce under irradiation by an electron beam while scanning the sample. This secondary emission ...

Terahertz dance of amino acids

RUB chemists explain the fingerprint of dissolved glycine in the Terahertz range

01-Apr-2014 - Chemists at the Ruhr-Universität Bochum (RUB) have, for the first time, completely analysed the fingerprint region of the Terahertz spectrum of a biologically relevant molecule in water, in this case, an amino acid. By combining spectroscopy and molecular-dynamics simulations, they rendered the ...
