Scientific work in Mendeleev University

The University conducts a lot of research from completely different fields of knowledge, one of the priority lines is energy resource-saving and chemical technology safety. Scientists at Mendeleev University are developing modern technologies for creating new-generation inorganic materials for construction, such as synthetic granite or glass-ceramics. The research works in the field of materials for the nuclear energy industry have been carried out in the University since 1949, and work in this direction continues to this day. The achievements in the field of rare-earth and dissimilar metals are particularly concerned with rhenium, hafnium, and zirconium, which is especially effective in energy, engineering, and jewelry. The scientists of Mendeleev University solve the problems of removing organic and inorganic compounds and heavy metal components from water treatment of nuclear and thermal power plants. The advantages of the method are evident. Power inputs are the lowest, chemical reagents are not used in this case. MUCTR has been directing the work of chemistry and applied chemistry Head Council attached to Ministry of Education of Russia, more than 15 research schools of scientists being up to world standard working in MUCTR to date. Here are some priority areas of research work at the University: energy and resource-saving technologies; new-generation inorganic materials; petrochemistry and oil refining; materials and technologies for the nuclear industry; materials for medicine and health care; nanotechnology; problems of sustainable development.

Dmitri Mendeleev

Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He created the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered. In the society of that time, he was treated differently. Someone criticized his work, someone called him a genius, but the contribution that he made to the development of science can not be overestimated. Chemistry, physics, hydrodynamics, meteorology, geology — everywhere he left his mark. During the 72 years of his life, he made many discoveries, for which he was respected throughout the world, but he never won the Nobel prize for his main creation, which we use to this day — the periodic table of elements.

The Periodic Table

The discovery of the periodic table is a long story. At first, John Newlands described a Law of Octaves, noting their periodicity according to relative atomic weight in 1864. Then there was Lothar Meyer, who published a paper in 1864 describing 28 elements classified by their valence. On 6 March 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence between the Properties of the Atomic Weights of the Elements, which describes elements according to both atomic weight and valence. The presentation stated that the properties of elements change periodically according to their atomic weight, which makes it possible to predict the properties of yet unknown elements. Mendeleev and Meyer published their tables at the same time. The success of the Mendeleev table was the presence of free space for the corresponding yet undiscovered elements and the location of the elements by properties, rather than by atomic weight. There are many ways the Periodic Table can be used. The atomic number, atomic weight, orbital arrangement of electrons, oxidation states, and valence of elements can all be found in the table. The table enables us to recognize families of elements. Finally, the table can be used to predict the properties of missing elements.
