Numerous industrial processes make use of blends. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have studied how the external electric field affects the rate of component separation in blends composed of polymers and liquid crystals and those composed of various types of polymers.
Researchers at the Stanford School of Engineering have delivered a nanoelectronic synapse that might drive a new class of microchips that can learn, adapt and make probability-based decisions in complex environments. Their work might one day lead to real-time brain simulators that enhance our understanding of neuroscience.
A team of University of Maryland nanotechnology researchers has solved one of the most vexing challenges hindering the use of carbon nanomaterials for better electrical energy storage and for enhancing the fluorescence sensing capabilities of biosensors.
Using a special laser technique, research scientists at the Fraunhofer Institute for Laser Technology ILT and other Fraunhofer Institutes have succeeded in producing hybrid biomimetic matrices. These serve as a basis for scaffold and implant structures on which the cells can grow effectively.
A novel approach to restoring sight using a 'bionic eye' is being investigated at Swinburne University of Technology. The laser stimulation of optic nerves is the focus of this research to develop a vision prosthesis - perhaps a tiny laser device fitted in a pair of spectacles - much like the cochlear implant for restoring hearing.
The sun has enough power to supply the whole earth with electricity. But in Europe solar cells make only a vanishing small share of renewable energy sources. Solar cell production is still an expensive process. And the photovoltaic cells can only exploit about 16 percent of the energy of the sunlight.
A Beijing startup called Wuhe is making electrode materials and batteries that could lower the cost of electric vehicles. The company uses nanostructures for battery materials that, like other recent nanostructures, let the materials deliver the large bursts of power needed for acceleration while maintaining energy storage capacity. But the Wuhe advance also makes the materials easier to work with than similar electrode materials, and as a result, it could cut battery-cell manufacturing costs by 10 percent.
If you were to look at a carbon nanotube with the naked eye you wouldn't see much more than black powder, but now a team of EU-funded scientists has developed a novel way of making these multi-purpose nanotechnology building blocks more visible.
CEA-Leti and Entegris, a provider of critical products and materials used in advanced high-technology manufacturing, have signed a two-year agreement to study cross-molecular contamination to and from semiconductor wafers and containers.
Imec announces that it has successfully fabricated implant-free quantum-well (IF-QW) pFETs with an embedded silicon-germanium (SiGe) source/drain. These devices show an excellent short channel control and a record logic performance.
Researchers at Columbia Engineering School have built optical nanostructures that enable them to slow photons down and fully control light dispersion. They have shown that it is possible for light (electromagnetic waves) to propagate from point A to point B without accumulating any phase, spreading through the artificial medium as if the medium is completely missing in space. This is the first time simultaneous phase and zero-index observations have been made on the chip-scale and at the infrared wavelength.
