Spraying nanopaper

New process produces extremely smooth cellulose layers on an industrial scale

11-Jul-2019

With a new spray coating process, very uniform layers of cellulose nanofibers (CNF) can be produced on an industrial scale. X-ray investigations at DESY's research light source PETRA III as well as investigations with an atomic force microscope and neutron scattering show how the layer is ...

Charge transfer within transition-metal dyes analysed

11-Jul-2019

Transition-metal complexes in dye-based solar cells are responsible for converting light into electrical energy. A model of spatial charge separation within the molecule has been used to describe this conversion. However, an analysis at BESSY II shows that this description of the process is too ...
