An application highly desired by the semiconductor industry is graphene's potential role as a replacement for silicon as a substrate in microchips. Thanks to an innovative technique for applying dielectrics (insulating layers) onto graphene, that goal is a bit closer to reality.
Researchers describe a development method using columnar thin films that is quick, provides a high level of detail and resolution, and yields consistent results on prints recovered from many types of nonporous surfaces.
Engineers have demonstrated that it is possible to generate nanostructures from silk in an environmentally friendly process that uses water as a developing agent and standard fabrication techniques. This approach provides a green alternative to the toxic materials commonly used in nanofabrication while delivering fabrication quality comparable to conventional synthetic polymers.
Consumers are demanding ever smaller, more portable devices, with extra features, better performance and energy efficiency. But squeezing everything into smaller packages is a huge manufacturing challenge. To help, European researchers have developed ways to produce the micro components needed for these smaller devices.
A new, extremely thin kind of light detectors was created at Vienna University of Technology. Two very different technologies were combined for the first time: metamaterials and quantum cascade structures.
An international team of researchers has managed to create an entanglement of 103 dimensions with only two photons. The record had been established at 11 dimensions. The discovery could represent a great advance toward the construction of quantum computers with much higher processing speeds than current ones, and toward a better encryption of information.
Fuel cells and electrical energy storage systems are increasingly emerging as the core elements for new mobility concepts and for forward-looking building energy management. Employing high-resolution micro- and nano-computed tomography systems combined with scanning electron and atomic force microscopy allows a full range of optical investigations.
