Found technological method of producing nanofibers.

Engineers from the University of North Carolina have modified a known method of manufacture of nanofibers, significantly increasing the speed of their output.

The process of forming fibers with a diameter of ~100-1 000 nm of polymer solutions is called elektrodrazenie. In the design of a typical setup for “spinning” stand out a pump that provides a continuous flow of liquid to a conducting needle, collecting plate and the high voltage source, generating a field between the needle tip and the plate. The solution is in contact with a metal needle, charged, and put into it the charges are accelerated by the electric field and involve in the movement of the surrounding substance, whereby the fluid is accelerated uniformly in the sky, in a thin stream. In the interelectrode gap, the solvent partially evaporates, and the stream turns into fiber, which is deposited on the plate and creates a porous layer.

Currently, the international aviation and space salon MAKS deservedly occupies a leading place among major world aviation forums.

The main goal of MAKS is to demonstrate Russian high technologies and openness of the domestic market of Russia for joint projects with foreign partners.

Researchers from the Taiwan Institute of industrial technology (ITRI) has created a new type of media called i2R e-Paper, text and images which can be printed and erased dozens of times.

Sheet i2R e-Paper is covered with plastic film with cholesteric liquid crystals which do not have Central symmetry. To get the image on this “paper” it is necessary to pass through a thermal printer. Erased by re-processing in the device.

The company Milleniata together with LG Corporation assumes in the very near future to develop the “eternal wheels” that can store information indefinitely long time.

Of course, in addition to discs will also be released the player who can not only read data from these disks, but to write to them. M-Disc can be read in any domestic player.

Australian designer Philip Legerski presented a draft promising sports electric vehicle, able to accelerate to a maximum speed of 500 kilometers per hour.
According to the developer, the purpose of creation of this machine, named B7, was an attempt to prove that cars of this type can be quick to look good and to manage and deliver driving pleasure.
The project Legerski involves the use in the power plant of the car is not heavy and expensive batteries, supercapacitors, which are more powerful, but smaller and lighter than lithium or metal hydride batteries used in existing electric cars. In the motion supercar will be using four electric motors – one for each wheel.

To look into the future, it is enough to have leisure, curiosity and imagination. So I predicted the crisis, and the subsequent hatred of the bankers.
Modern futurology — something between a prose of Arthur C. Clarke and the division of scenario planning for Shell. For example, I sell a mix of lectures, research markets future food or future media and forecasts specific to the company for 10-20 years. So I created scenarios banking-2012 public libraries-2030, education-2025. Reading a lot of specialized literature, I thus use not only their imagination, but also strangers.

Researchers from the University of Manchester, together with colleagues from the universities of East Anglia, York and Nottingham, UK, are using nanotechnology to convert solar energy into a clean fuel.
The solar energy potential is vast — just one hour of sunlight provides as much energy as man uses in a year. But nobody has yet to figure out how to use that enormous energy to produce the fuel.
Professor Wendy of Flavell (the University of Manchester and her colleagues are working to create a solar nano-device on “quantum dots” — small bundles of semiconductors that absorb sunlight. The principle of operation of the device is as follows: when sunlight is absorbed, the temperature rises on semiconductors and their conductivity increases. Then acting on the molecules of the catalyst located on the surface of “points”, they create new fuel.

Recently, we often see prototypes or concepts of the devices based on the use of cutting-edge technologies and the latest achievements of science, by which blind people and people with sight disabilities gain the opportunity to “see” the environment
The closest to mass production of such a device is a device Virtual Cane, which using the principle of sound sonar, allows its users to “see” physical objects at a distance up to 10 meters. The device is composed of a emitter, which emits a stream of inaudible sound waves that are reflected from objects and carry back information about the size and the distance to the object. The system informs the user of the vibration oscillations, the frequency and intensity of which depends on the size and distance of the object.
