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.

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
