Believe plastic but powerful that the steel

Scientific of the University of Michigan they created a light compound, similar to the plastic, more consistent and more brilliant than the steel. The material could be useful to improve products in microtecnología like microchips and biomedical sensors.

A group of American scientists of the University of Michigan could make actual the dream of any fanatic of the science fiction cinema when manufacturing "the transparent" steel. You are anything less than of a fine and light plastic as a paper sheet, but as resistant as the steel.

The material is compound for clay and a nontoxic very similar paste to the one that the children use in the school. Also, the plastic substance is biodegradable and, just as Nicholas it assured Kotov, educational manager of the investigation, your elaboration sues very little energy, money and you are completely ecologic.

According to the scientist, the invention it is ideal to design safe-deposit suits for military or policemen, or, to recover your vehicles by way of blindage. The investigators also recommended other utilities, as using it to reduce the required energy to separate gases in chemical factories, or to improve products of the microtecnología like microchips and biomedical sensors.

For long time, the scientists have tried to produce a material compound with blocks of microscopic sizes that could maintain your force. Kotov was able to make it imitating the molecular structure, as of bricks and cement that he/she are in the marine shells. "When you have a structure of bricks and cement, any blow is cushioned by each interface", the expert explained to the magazine Science.

The University of Michigan assured that Kotov already began to develop practical applications for the plastic compound that you/they could be marketed in one or two years.

They develop more resistant aluminum that the titanium

A team of investigators of the University of Buenos Aires and of the University of Oxford they have developed a metallic more resistant alloy that the titanium.

The aluminum alloy contains "particles that have a very particular" form because they are "almost crystalline", Fernando Audebert, director of the Group of Advance Materials of the Ability of Engineering of the University of Buenos Aires said.

"We fuse the aluminum with other elements to 1.100 or 1.200 grades and we cool it a thousand grades in a millisecond. In that process we retain particles icosaedrics, as if they were cores, and that contributes to the material a very high submitted. The secret is in the combination of elements, in the indictment of the alloys and in how you cool down" them, the investigator explained.

To achieve that cooling speed, the team used a technique that suppose to pour the warm liquid of the alloy on a copper wheel that you turn to towering speed in a chamber of blank. "The stream solidifies on that surface and you leave in tape form or fleje. What are made later is to chop it, to mill it and to zip it", you assured.

The utilities are many, overalls in the automotive sector, where you will be been able to use in the production of pistons for competency files or compressors for turbines of gas.
