If China, for its effort to support and develop national research and industry in electronics, microelectronics and nanotechnology, is poised to position itself among the world leaders in these areas, it still has some difficulties in imposing its products scale. Thus, the chip LCoS (Liquid Crystal on Silicon for, based on a new technology of video projection, especially used for liquid crystal displays and operating by reflection through a reflective layer placed between the transistor TFT – Thin-Film Transistor – and liquid crystal display), have been independently developed by China to offer a national alternative to products developed abroad.

With a device to the micro-compression and compression nano-situ, researchers at Riso DTU has shown that the deformation of micro and nano depended mainly on the size of their crystals. Their research opens the way for the use of such knowledge in the field of nanoproduction of micro-electro-mechanical systems such as digital microphones, pressure sensors in miniature water pumps, or accelerometers used in airbags .

The precise manipulation of nanowires in nanotechnology or biotechnology in single cells, traditionally made with mechanical micromanipulators oriented manually, often requires relatively long times, which increase the risk of damage to the sample. This drawback could be remedied by a robot designed by three engineers from the Ecole Polytechnique Federal de Lausanne (EPFL), according to its inventors manipulate with nanometer precision five to ten times faster objects of interest.
The miBot Imina of technology comes in the form of a parallelepiped with a size slightly larger than a thimble, extended by a manipulator arm. At the end of this arm can be set different tools, including pliers, micro-needles, or spikes tunneling microscopy. The control of the robot and its mechanical arms are controlled by external electronics. The user controls the movements of the robot using a joystick.

Scientists at the Joint Research Center Dresden-Rossendorf FZD Leibniz (Saxony) [1] have managed to develop transistors based on germanium, which have a frequency switching even faster. The new transistors can also reach levels higher production, promising and production costs lower.
Germanium has been the material of the first generation of transistors, before being replaced in the 60s by the silicon.

The oligopirroles are a type of organic compounds with increasing interest in the area of new materials and nanotechnology. In the Department of Organic Chemistry of the UAM group led by Dr. Juan Carlos Carter has developed a novel method of synthesis of these compounds with complete control of the size of the string oligopirrolica.
The
pyrroles are
chemical compounds whose pentagonal cyclic structure containing four
carbon atoms and one nitrogen. The union of two pyrroles by their carbon chemical bond leads to a dipyrrole, if they join the three
pyrroles product is a tripirrol and, ultimately, when joined several units of pyrrole the resulting structure is called oligopirrol. Such compounds can be visualized as a molecular chain in which each link in the chain is a unit of pyrrole. The
oligopirroles have great potential in the areas of nanotechnology and new organic materials, especially due to its excellent properties such as electron conductors, liquid crystals and ion-selective complexing.

The cup, which magically wash themselves? In the near future, such a miracle could become reality. Saarland, a nanotechnology company has now developed a substance that can run off almost anything – even bacteria and fungi have no chance.
German nanotechnology have developed a coating that will come with some certainty on a similar significance for everyday life like in France in 1954, invented for Teflon pots and pans.
The new, scratch-resistant and heat resistant material is biologically safe, nontoxic and boundless nachgerade applicable – not only for kitchen appliances, or textiles. It is also striking effects such as wood, leaves or living in the drag-flow optimization of aircraft. The material layer is extremely thin, flexible, and even breathable. Their basic material is silicon. It is this mineral used in glass production and accounts for 15 percent of Earth’s mass. Supply problems with the cheap raw materials, it will not give.

Graphene, the rising star of materials for the electronics of the future, is widely studied in the world of nanotechnology by many research groups around the world. A team of researchers at the University of Illinois at Urbana Champaign, led by the Group Director of Nanoelectronics Joseph Lyding, and the doctoral student Kyle Ritter, showed experimentally properties on behavior and metal semiconductor that material. Indeed, the researchers said,
