New high-speed method for spectroscopic measurements

23-Jun-2021

Researchers at Tampere University and their collaborators have shown how spectroscopic measurements can be made much faster. By correlating polarization to the colour of a pulsed laser, the team can track changes in the spectrum of the light by simple and extremely fast polarization measurements. ...

Quality assurance in cells power plants

14-Dec-2017

Mitochondria generate most of the energy cells need through a respiratory chain for which they must produce their own proteins. The research group of Associate Professor Henna Tyynismaa, University of Helsinki, Finland, has discovered a "quality control" mechanism in the mitochondria, which is ...

New microscope sets a record for visualizing surface wetting properties

29-Nov-2017

Wetting is an everyday phenomenon that represents how well liquid spreads on a surface. When water comes into contact with an extremely water-repellent, or 'superhydrophobic' surface, droplets bead up and roll off easily. Aalto University researchers have developed a measurement technique called ...
