Speed record in a silicon chip covered trail of broken lead

A track is capable of electrons moving at high speed is a new record for the silicon chip, which is the cornerstone of IT.
Electrical resistance requires strict limit speed of the electrons passing through silicon. To break this limit, the computer scientists trying to replace silicon with carbon, such as thick sheets of carbon in person, or a chart, the current guidelines better Than Any Other substance at room temperature.
The figure of this property because of an unusual interaction between the lattice structure and electronic structure of the individual. This brings to reality the mass of free electrons to zero. The apparent lack of gravity allows the graphics, like photons zip at speeds up to 0003 the speed of light in vacuum.
The problem is that the graphics are difficult to mass. Now, Han Woong Yeom, and his team Pohang University of Science and Technology in South Korea believe they can emulate the conductivity of silicon. You must be registered electrons 20 times faster than their typical silicon chip.
Yeom team has a person in a thick layer of lead on the surface of a silicon block. Since the primary layer is so thin, the arrangement of atoms of silicon atoms under the influence. Team leaders are suspected of electrons, which in turn influences the electronic structure of silicon interface.
To study, provided that the high-energy photons with the material to the electrons hit, and measure the movement and energy. contributed by subtracting the photon energy for the electrons displaced, has calculated that some of the electrons in the interface of silicon leads to an apparent mass of electrons 1/20th of a typical silicon chip (Physical Review Letters, DOI: 10 1103 / had PhysRevLett .104.246803). "This is the fastest 20-time champion of electrons," Yeom said.
This is still only one third the speed of electrons in graphene, but in principle, the electron mass can be further reduced - and speeds - are coated with different metals, silicon can be used, he adds.
"This is a big step forward," said Zahid Hasan, Princeton University. Speedy Silicon Graphics followers could easily be avoided on the shelves, as the production infrastructure already exists, "says Hassan.

Opera Mobile 10.1 beta for Symbian S60

The Opera team has only a beta version of Opera Mobile browser for Symbian S60 devices released for implementation. 10.1 beta comes several months after its predecessor and takes only a few new features, but users of S60 is very interesting for you to try.
Opera Mobile Beta for Symbian S60-10 devices were found last November, his successor, and now you can enjoy the beta 10.1. Besides the usual features such as dialing, tabbed browsing, password manager, turbo Opera and Opera Link, which will now have the latest version of the performance of the engine, Soon, the Library and Opera Vega JavaScript Caraka machine graphics.













Moreover, the latest Opera Mobile on smartphones S60 geolocation support (many Web services are the most relevant content based on their current location selection), and improved angular displacement, rotation (portrait packages landscape display) and a virtual keyboard.
If you have a S60-based smartphones (or third or fifth edition), and the desire to maintain the 10.1 Beta of Opera Mobile for Symbian S60, you can download from the links below.
