At this year’s plastics trade show in Düsseldorf (October 27 to November 3, 2010) the Fraunhofer ILT is presenting the TransTWIST laser-based plastics welding machine at the Fraunhofer-Gesellschaft stand (E91) in Hall 3. In live demonstrations the researchers will show how two transparent joining partners made of plastic can be lap-welded using laser radiation.
In conventional laser welding a suitable radiation absorber is normally applied to the underlying joining partner. This is time consuming and costly. Furthermore, the appearance of the component or weld is affected by the color of the radiation absorber.Nearly invisible welds
TransTWIST shows a great potential for use bio-biomedical field, especially microfluidics, packaging industry and in design applications.Contacts at the Fraunhofer ILT

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
