This is the second your vacation professor at the University of Notre Dame, Indiana Alexander Mukasyan hold at the sea without traveling in search of the exotic, but in a stuffy Moscow. National Research Technological University "
Why? After all, he perfectly knows our realities. There are many reasons why doing science is much more complicated than in the West. One academic bureaucracy that costs. Clearly, when Russia come reputable foreign scientists, winning megagranty of 150 million rubles. Amount is impressive. We Mukasyana it much more modest — only 30 million.-I am well aware about the working conditions in the Russian science, — says Alexander. — Although the left here 16 years ago, but spent many years in academia, where he defended his doctoral and master’s theses. I am very indebted to Russia and always wanted to help her. A agreed to this project because I saw young people who burn the eyes. They want to do science. A few years ago this was not. I think the situation is changing, and this is encouraging. After all, the country has lost two generations of scholars, and, in my opinion, to make up for this loss — the main task of the Russian science.
Professor Field of Interest Mukasyana — solid flame. Here he is one of the most prominent experts in the world. By the way, this technology was developed in the USSR by his teacher academician Alexander Merzhanov. It allows to connect the refractory elements such as tantalum and carbon to obtain compounds with unique properties. So, on the basis of tantalum carbide created the most durable of all man-made materials that are able to now get a scholarship.
— What is the method? — Explains Professor Mukasyan. — You take tantalum and carbon powders, mix them, and then to root point of the laser beam millimeter. Local warming initiates a reaction that gives off a lot of heat. It quickly as the fire spreads throughout the volume of the substance, in seconds making it a refractory tantalum carbide. Everything happens in vacuo, and forms no melts and gases. Hence the name — solid flame. Its advantage over traditional methods of preparation of this material is obvious: large energy savings. After all, usually using special furnaces, high temperature, and synthesis for tens of hours. And then quickly, efficiently and cheaply.
Mukasyan decided to apply the already world-recognized method for creating nanotechnology refractory ceramic materials. At first glance, it seemed unreal. It is well known: the high temperature and nano incompatible. When heated, the particles begin to grow, and the whole effect of the nano is simply lost. But the scientists found just three options to solve the problem.
Since one of the purposes of research, which is created by Professor Mukasyanom in MISA Center of ceramic nanomaterials konstraktsionnyh — non-porous carbide ceramics flint. Today this material — world champion in opposition to high temperatures in oxidizing environments. In particular, on the basis of this material was made famous paneling of shuttles. The widest range of application: aerospace, aviation technology, defense, oil and gas, microelectronics, ID Therefore, the demand for it is growing rapidly. The market is divided between the major players. But the Russians have a chance to penetrate it, figuratively speaking, through nano. The essence is the same as that of tantalum carbide. Receive such ceramics is not the usual way, spending a lot of time and energy, and by applying a "solid flame".
— It allows you to reduce the sintering temperature of the nanopowder at 2400 C and 1700 C, and reduce the time from days to one hour — explains Mukasyan. — With these parameters nanograin not grow, which allows us to obtain a pore-Nanoceramics. If we all succeed, I believe that I am in the business of MISA did.
According to the professor, research is progressing well. Centre has already sent to prestigious scientific journals five articles, and presented two patents.
