New Aerogel Products for Construction Use: Product Specifications, Application Examples, Practical Aspects [PDF]
Two new high-performance insulation materials (HPIM) for the usage in buildings are presented. We show how to use and apply the upcoming aerogel products and give examples for structural details. While both materials achieve very low lambda values due to

3D/4D Printing of Polyurethanes by Vat Photopolymerization
Vat photopolymerization relies on the light‐induced polymerization of liquid photopolymer to produce the targeted structure. Among all the polymers prepared by vat photopolymerization, due to their numerous properties polyurethanes have recently gained ...
