UNUSUAL ON INGREDIENTS CERAMICS OFFERS OPPORTUNITIES FOR SUPERCONDUCTIVITY

UNUSUAL ON INGREDIENTS CERAMICS offers opportunities for superconductivity

Ceramic materials based on mednokislyh connections allow the development of new high-temperature superconductors, physicists believe from Ohio State University.

The researchers found that the so-called mednokislye ceramic materials serve as a switch between two different types of superconductivity under certain conditions.

The results of studies have been reported in two papers published in recent issues of the journal Physical Review Letters.

Mednokisly material may serve as a very good insulator. And changing its composition is so small that it can be a good superconductor.

This discovery could settle the growing controversy among scientists and to direct the path of buckyball-like superconductivity in ceramics.

Scholars have argued that mednokislye v is a superconductor for the so-called: d-wave or s-wave, explained Thomas Lemberger, a professor of physics.

The difference depends on the electrons within the material are placed. Materials with wave behavior more desirable because they have the best technical properties at high temperatures. Unfortunately, most high-mednokislyh compositions seem to exhibit the behavior of d-wave.

But the wave superconductivity at high temperatures is still possible is the goal of the current study.

For example, buckyballs-like ball-shaped carbon molecules discovered by Bell Labs (the system of research laboratories around the world, created by the company of the same name) in 1991, show the wave superconductivity at 40 degrees Kelvin (-233 | C), - very high temperatures for superconductors. Achieve these limits allowed buckyballs with potassium.

Now Lemberger and his colleagues can change the behavior of a class of compounds mednokislyh, changing the properties of d-wave to s-wave if they will make further in the material enough cerium - the usual ingredient used in creating glassware.

Mechanisms of behavior of both types of materials - a kind of gift. If you make it to the action to suppress one of the behaviors mednokislogo connection, latest automatically switch to the other.

Opening in 1986 mednoksilyh connections puzzled scientists. Ceramics - the usual insulator, but when it is associated with the atoms of elements such as lanthanum and cerium, mednokislye materials suddenly become excellent conductors.

Scientists create thin films mednokislyh compounds, adding thereto varying amounts of cerium and perform observation as sequenced electrons within the material itself. Measurements were made on the basis of an analysis of how deeply the magnetic field can penetrate through each film.

Scientists have speculated on what mednokislye materials can withstand wave superconductivity at temperatures up to 90 Kelvin (-183 | C). This would make the materials useful guides for commercial electronics. If metallic conductors were replaced superconducting ceramics, devices would be more effective, and it would be possible to create a fundamentally new types of devices.

COMPLETED CONSTRUCTION 33 WIND TURBINE

COMPLETED CONSTRUCTION 33 wind turbine

33 wind turbines, each rated at 600 kW, were installed in Grobiņa (Liepaja District) jointly by the Latvian company Latvijas energoceltnieks (LEC) and the German Enercon. Installation of wind turbines in Grobiņa - one of the most significant energy projects implemented by our company - said General Director of the LES Andris Puce. - This will be the largest source of alternative energy in Latvia. Previously, the total project cost was estimated at about 20 million USD.

It would seem, should only be glad that we have developed competition and emergence of independent producers of clean electricity. However, the project has disadvantages too short.

As has been reported, , a group of eleven companies of similar Veja parks (Veja parks 10 ... Veja parks 20) was among the lucky few who have received the opportunity to realize the double tariff electricity. It happened shortly before the abolition of the stimulus rates.

And experts still question the legality of the transaction. After all, in force at the time the legislation for such a tariff could claim only low-power wind power station (WPS). In this case, de facto it was serious about building wind farms.

Although de jure everything looked beautiful - 11 companies receive 11 licenses for the construction of 11 wind turbines with a capacity of 1.8 MW each.

But the most important thing, thanks to the project grobinskomu other companies willing to invest in wind power tens of millions of euros, while not claiming to be supertarify are unlikely in the near future will be able to realize their plans. Thus, in 2002 the government approved the zero quota for the construction of new wind farm. This is explained by the fact that because of purchases by stimulating the average tariff rates for electricity in the state could increase by 1.7%.

A state energy policy allows for growth over five years is not more than 5%.

Potential investors (and build a wind farm with capacity from 30 to 100 MW are ready to German, British, Swedish firm) had hoped that the project Veja parks by the end of this year will not be realized and its license is canceled. However, their hopes were dashed.

What will happen next? In their declaration, the government announced its intention to Repshe to promote Latvia#39;s independence from imported energy and to support economically viable projects on the use of renewable energy resources. However, experts fear that the next year will be allocated zero quota for the installation of new capacity.

Indeed, the main consultant in the new government will be the same as the old - GAO Latvenergo.

TRANSISTOR IBM OPERATES AT FREQUENCIES OF 350 GHZ

TRANSISTOR IBM operates at frequencies of 350 GHz

On Monday, IBM introduced a new design of transistor circuits for wireless communication, which promises to provide sufficient power to create networks of the future that can change the way people use wireless networks at work and at home. The new design of the transistor based on silicon-germanium (SiGe) technology, will provide a three-fold increase in performance. Department of Microelectronics IBM tells in detail about the details of this design at the International Conference International Electron Devices Meeting (IEDM), to be held in December in San Francisco.

New IBM transistor operating frequency 350 GHz clock rate will allow communication chips approximately 150 GHz and the data rate of hundreds gigabits per second. This is enough to transmit, for example, high-quality video from the TV adapter on a high resolution screen. Clock rate, these chips will be four to five times faster than the fastest chips used today in wireless LANs and home networks, and the energy they consume about 90% less.

SiGe technology is the incorporation of germanium atoms in different sites of the crystal lattice of silicon. This facilitates the flow of electrons through a transistor that can be used to improve performance or save energy. The rest of the manufacturing process is different from the manufacturing process conventional silicon chip, which makes mass production of its relatively low cost. According to the IBM, the chips with a new 350-GHz transistor will start to appear in 2005-2006.

In June 2001, IBM introduced the transistor with an operating frequency of 210 GHz, and the chips based on it should be on the market at the end of the future or the beginning of 2004.
