The three-dimensional distribution of electrons inside molecules has been made visible for the first time at PTB's electron storage ring Metrology Light Source (MLS) in Berlin-Adlershof by means of electron spectroscopy. For this purpose, molecules which were aligned on a metallic surface were irradiated with shortwave ...

Within the scope of a cooperation project with the National Institute of Metrology (NIM, China), researchers succeeded at PTB in improving the uncertainty in the realization of the SI base unit "kelvin" via the triple point of water to less than 20 µK at PTB. In addition, ...

By means of improved measurement procedures, PTB employees from the field of spectrometry with synchrotron radiation have succeeded – in cooperation with partners from industry – in experimentally confirming the different energy dependencies of partial photoionization cross sections which could so far be predicted only by theoretical calculations. Due to this, the quantification approach of an...

The kick-off meeting for the project "Seven Nanometre Technology" (SeNaTe) has recently taken place on the occasion of IMEC in Leuven and within the scope of the EU programme "Horizon 2020" in the ECSEL call 2014-2 "Innovation Actions". PTB is one among 41 partners taking part in the 3-year project for the development of the technological infrastructure for the manufacturing of semiconducting ...

To determine the Boltzmann constant k which is necessary for the redefinition of the SI base unit of thermodynamic temperature, the kelvin, numerous research groups are using acoustic gas thermometry (speed of sound measurements) which has provided the most exact values so far. PTB has followed an alternative, completely ...
