Surface roughness and chemistry of battery foil, key to better battery

The project goal is to improve the surface properties of aluminium battery foils (current collectors), with a special attention to surface roughness and wettability. These surface properties have a crucial role for the function an…
Project

BioSusTex - Towards Absolute Safe and Sustainable Biobased Textile

The textile value chain involves a diverse range of materials, end users, and complex applications. Although there is a shift towards greater sustainability, progress is slow and requires more innovative technologies to address is…
Project

Anti-reflective coatings for solar collectors

In the project we are developing an anti-reflective coating on the cover glass of solar collectors, which will result in an increase in the efficiency.
Project

FunCoat – Functional Coatings for more energy efficient heat pumps

The aim is to decrease the problems with frost by developing functional coatings on the heat exchanger surfaces, which would lead to large energy savings due to a reduced need of defrosting.
