At Stand 4211 in Hall 4 of Fakuma (October 13 - 17, 2009, Messe Friedrichshafen), the Fraunhofer ILT will be presenting a novel, compact and industry-ready plant concept to laser weld plastics using fiber lasers.
Bonding metal to plastic with a laser-structured metallic surface and subsequent extrusion.
A TWIST®-welded microfluidics component, minimal canal width < 50 µm.
Thanks to the TWIST® radiation concept, a quick, temporal and localized beam modulation forms the basis for this new laser method. Fraunhofer ILT's researchers in Aachen have developed and qualified TWIST® - "Transmission Welding by an Incremental Scanning Technique" - an innovative process to weld plastics.
When compared to standardized laser plastic welding plants, this new concept significantly reduces investment costs as well as plant size, and is nearly maintenance-free. Furthermore, the TWIST® plant concept is characterized by its higher process speed and flexibility when structuring welding contours, as compared to conventional joining methods. Hence, it is particularly suitable for small and medium series, which require quick retooling. By using new wave lengths in combination with the TWIST® concept, operators are now able to weld transparent components together without an infrared absorber and at high speeds.
To bond metal with commercially available plastics, the Fraunhofer ILT has developed a laser-supported joining process that can dispense with using additional material. A suitable structuring of the metal's surface at high speed allows form fit joints to be attained above the bonds with high strength.Contact person 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

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...
