Printed electronics, for example in solar cells, sensors or displays, are becoming increasingly popular on the mass market. Apart from the possibility of new functions and designs, productive deposition methods and the flexible materials used promise significant reductions in production costs.

The short lifetime of the products has often been an obstacle to their widespread commercialization up to now. The main reason for this is the high sensitivity of the electronic functional materials inside the devices, which can be damaged by water vapor and oxygen.
The Fraunhofer Institute for Electron Beam and Plasma Technology FEP in Dresden develops vacuum processes to productively seal polymer films roll-to-roll with so-called high-barrier and functional layers. A standard polymer film would allow large amounts of water vapor and oxygen to pass through. Permeation barrier layers prevent gas diffusion and thus protect the active, organic materials. In addition to the barrier function, the film can also be enhanced through further, application-related functional layers. For example, the optical properties of the film can be adapted or transparent electrodes can be added on top of a barrier stack.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
