The situation regarding titanium is paradoxical. On the one hand, titanium is found in abundance in the natural environment: in terms of natural occurrence in the earths crust, the element is the third among all metals, directly following iron and aluminium. In industry, particularly in metallurgy it is used very rarely, about one hundred times less than aluminium. This happens in spite of the outstanding properties of titanium: it is lightweight, fast, heatproof and chemically stable. But it is too expensive as it is very difficult to extract it from minerals, and the raw materials for its production are extremely expensive.
It came to having to purchase titanium dioxide from abroad. It is used as a basis for titanium white, and the production of plastics, paper and even cosmetics. There are enough deposits in Russia; the problem is that Russia has not yet managed to establish the production of high-quality raw titanium.
This stumbling block will probably be removed soon with the help of the technology developed in the Baikov Institute of Metallurgy and Material Authority, Russian Academy of Sciences(IMET RAS), in the laboratory of Professor Reznichenko by G.B. Sadykhov, Doctor of Science (Engineering).

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
