This allows wrappings, mobile phones, CD jewel cases and laptops to be given an attractive new look. The technology is suitable for mass production and can be integrated into existing printing presses. Iscent Oy, a new Finnish enterprise, is commercialising the technology jointly with VTT.
Applications of the technology include the ability to label genuine brand products with a technical solution that is difficult to counterfeit. Printers can reduce the use of inks with this method, and advertising agencies can create striking packages that are environmentally friendly. Applications further include transparent films and gift wrappings, which can be made more decorative without compromising transparency. The technology is also suitable for injection-moulded plastic products such as mobile phone shells, CD jewel cases and laptops, and for laminate solutions such as interior design elements and sports equipment.
Commercial holograms in the printing industry are almost without exception printed on narrow-web lines. Iscent is investing in the capacity to produce end product up to 1,200 mm wide, which will open up a completely new range of business opportunities, enabling large-volume product lines thanks to minimised raw material costs.
Commercial holographic technologies are based on metal foiling or coatings, laminated structures and UV curable varnishes. With the new light scattering method, none of these will be needed, nor will any other extra materials: the rainbow colours are generated simply by altering the topography of the plastic or paper surface being treated.
The new method is based on a hot embossing technology where a pair of rollers similar to a calender exerts nip pressure on the plastic or paper web run through them. The lattice design on the main roller is copied to the web by the heat and pressure.
Iscent Oy, based in Tampere, Finland, is commercialising a new, high-quality optical effect film material. Iscent supplies film materials to Finnish and foreign companies and licenses its technology to converting industry of film materials. The new method enables cost-effective production and has a potential worldwide market. The technology can be licensed internationally for a scalable business 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...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
