From wood waste to high-performance polymers

A transparent and thermally stable polyamide – 100 percent biobased

31-Aug-2018

The natural substance 3-carene is a component of turpentine oil, a waste stream of the production of cellulose from wood. Up to now, this by-product has been incinerated for the most part. Fraunhofer researchers are using new catalytic processes to convert 3-carene into building blocks for ...

Clean through solar power

03-Aug-2018

In combination with the right materials, sunbeams can work wonders: they clean building facades and decompose pollutants from the air or in the water. The magic word is photocatalysis. In practice, though, the effectiveness of this „miracle cure“ fluctuates greatly, depending on the material used ...

Evaluating risk of hydrogen embrittlement

New simulation of cold cracks in high-strength steels

04-May-2018

High-strength steels play a vital role in the construction of modern vehicles and machines. If these steels are welded during the production of components, mobile hydrogen atoms can cause problems within the material: the atoms accumulate slowly at highly stressed areas of a component, resulting ...
