NEW SILENT COOLER FOR POWERFUL PROCESSOR IS EXPECTED IN SHOPS IN JANUARY

The Israeli company Active Cool shown at Comdex its already made a splash design - cooler for processors AC4G.

AC4G consists of two main parts of the power unit and the cooling unit. The power supply is installed in a free PCI-slot and feeds electricity to the cooling unit itself, in turn, is connected to an external power outlet. The components of the cooling device: the cooling plate, the powerful thermoelectric device with special properties, radiator and fan.
Cooling plate firmly against the CPU. A thermoelectric device removes heat from the heat sink plate and transmits to the radiator. Fan, in turn, removes heat from the radiator.

The power supply AS4G a microprocessor data processing system temperature and CPU temperature coming from the temperature sensors. Depending on the temperature of the microprocessor determines the operation mode of the thermoelectric device and the fan speed. Since the thermoelectric device performs most of the work on cooling system, the fan on the radiator usually runs at only 50% capacity, which significantly reduces the overall noise of the system unit. Manufacturers promise that even when the heavy for the applications processor, its temperature set at AC4G not rise above 72 degrees.

The cost of the device is about $ 120. Active Cool AC4G will be sold through the channels of Thermaltake, starting from January 2003.

PLUTONIUM IS A SUPERCONDUCTOR TOO

Plutonium is a superconductor TOO

A team of scientists from the Los Alamos National Laboratory, USA, and the University of Florida Institute of transuranic elements (Germany) under the direction of John Sarrao (John Sarrao) first discovered the effect of superconductivity in plutonium.

Found that fusion of plutonium, cobalt, and gallium becomes superconducting at a temperature of 18.5 Kelvin. The unusually high transition temperature may indicate that the substances on the basis of the plutonium may represent a new class of superconductors - in addition to the already known conventional superconducting materials, high-temperature copper oxides and the so-called vysokofermionnym systems.

The transition temperature at a plutonium alloy is an order of magnitude higher than that observed in vysokofermionnyh systems (substances containing uranium and cerium). The material also has a high critical current, making possible its application in industry in areas where high radioactivity of the plutonium is not an obstacle.

Effect of superconductivity were revealed in the measurements of magnetic susceptibility and resistance over a wide temperature range.

Scientists hope that further studies will be able to detect superconductivity and other transuranic elements with less toxicity.

UK TERAHERTZ LASERS IS ON THE WAY

UK: Terahertz Lasers are on the way

The generator consists of a titanium-sapphire laser frequency standard glass Fabry-Perrot and photoconductive antennas generating terahertz radiation at the difference frequency (difference frequency generation, DFG). It uses two laser light beam are very close frequencies A and B, which is formed by mixing radiation of frequency equal to the frequency difference A-B.

Although the technique DFG previously used to generate terahertz radiation, the novelty of the invention consists of Leeds scientists that the two beams A and B are not generated by two different lasers and the same. Thereby, there is no need to synchronize the two separate lasers the frequency and the further alignment of the laser beams, whereby the system is more compact and reliable. In the long term this could lead to cheaper and more compact customizable terahertz sources than currently exist.

By varying the thickness of the Fabry-Perot, you can adjust the frequency of radiation at this time demonstrated lasing frequency of 0.3 and 0.5 THz.

It is assumed that the frequency range of the new device will be able to cover the range of microwave frequencies in the region up to a few terahertz. The radiation power is limited to a conversion efficiency of the pump and at the present time is about 1 microwatt in continuous mode.

A NEW METHOD OF MAKING POWERFUL PERMANENT MAGNETS

A new method of making powerful permanent magnets

New type magnets composed of two phases - phase high coercivity, and a soft magnetic phase with low coercivity (magnetic field strength required for complete demagnetization of ferromagnetic material). The first phase provides a high anisotropy of the material and the magnetic soft - a high magnetization. Both phases interact via exchange interaction (exchange coupling).

However, managing the interaction of the two components should be carried out at the nanoscale.

Staff at TJ Watson Research Center of IBM Corporation in New York under the guidance of the Chern Hao (Hao Zeng), together with colleagues from Louisiana Technical University and the Georgia Institute of Technology have developed an original method of self-assembly of nanoparticles. As the building blocks used in the assembly of nanoparticles of iron-platinum and iron oxide Fe3O4. The components are mixed, then the conditions under which self-assembly takes place. The maximum magnetization of the new material is achieved by choosing the size and composition of the nanoparticles.

Currently this way able to obtain two-phase material, the maximum magnetization that is 50% higher than conventional platinum-iron magnets.
