    Sammanfattning : We were interested in investigating the stabilisation behaviour of 6-aminouracils, a new class of heavy metal free thermo-stabiliser for PVC. We have therefore investigated the performance and mechanism of stabilisation for 1,3-dibutyl-6-aminouracil, both alone, and in combination with a sodium perchlorate co-stabiliser. LÄS MER

    Sammanfattning : The current society undergoes a global energy transformation from fossil fuels to renewable energy. The alternative energy sources to fossil fuels are key factors to accelerate the transition towards a sustainable energy system. Among those, electrofuels (e-fuels) is a promising group that remarkably benefits overall carbon neutrality. LÄS MER
