MaletinaNational Research Tomsk Polytechnic University Russia, 634050, Tomsk, 30 Lenin Avenue, ai_cherepanova@mail.ruNanotechnology is one of the priority directions of the development of modern science. Annually revolutionary changes are occured in various areas of technologies: electronics, mechanics, medicine, chemistry using substanc-es and materials, the dimensions of which do not exceed 100 nm. Notable examples of these materials are metals Cu, Fe and their oxides.Use of nanoparticles of copper, most often caused by its antibacterial properties found broad application in surgery [1]. Devices for data recording of ultrahigh density are considered as interesting use of nanopowders of iron [2]. As components of ceramic paints these nanopowders still weren’t tested though their properties- a big specific surface, chemical activity in certain  Секция 7 Химия и химическая технология (на английском языке) 193temperature intervals, assume possibility of receiving unusual color effects.Therefore the purpose of this work is to study the influence of nanopowders of copper and iron on coloring of a glazed surface.As samples for researches the nanopowders of copper and iron received by the EEP [3] method were taken/ In the presented micrographs, it is possi-ble to notice big agglomeration of nanoparticles which sizes make of 50–80 nm.According to ZAF Method Standardless Quantitative Analysis an ele-ment ratio in nanopowder of iron was 98.16 % Fe and 1.84 % O; in copper nanopowders it was 91.45 % of Cu and 8.55 % of O.Nanopowders of metals were mixed with lead-free frit in various ra-tions and formed samples of a cylindrical form. It should be noted that, when mixing with oxidic powder metal agglomerates were easily collapsed. Firing was carried out in vacuum at 920 °C (speed of increase in temperature was of 60 °C / min, endurance 120 sec).The received samples have various shades: emerald (copper) and claret (iron) with wavelengths from 494 to 591 nm. With increase of nanopowders concentration the intensity of the coloring increases.References 1. Alekseeva T.P.

It plays an important role in the nervous and immune systems, besides cholesterol involved in lipid metabo-lism. It is well-known fact that high concentrations of cholesterol in the blood can lead to cardiovascular diseases. According to statistics from the World Health Organization, 17.5 million people died from cardiovascular diseases in 2012, representing 31% of all global deaths [1]. Therefore, control of cho-lesterol blood levels and cholesterol food levels is of great importance.There are several methods of cholesterol determination. The most at-tractive for this purpose looks electrochemistry, due to its simplicity, rap-idness and low costs. Sensors give an opportunity of size minimization and real-time analysis. Earlier was developed enzymatic sensor [2]. Usage of enzyme helped to improve the selectivity of sensor. Enzymatic sensor was based on hydrogen peroxide detection, which was generated by cholesterol oxidation on Cho-lesterol Oxidase. This type of determination has disadvantages, such as inac-curacy due to its indirect nature, enzymatic sensitivity to storage conditions.Voltammetric determination depends on the nature of electrode material, and also depends on the potential at which the electrochemical reaction of an-alyte takes place. Cholesterol itself doesn’t give a selective electrochemical response. In the present work the working electrode surface was modified with 2,6-diacetyl-2,4,6,8-tetraazabicyclo[3.3.0.]octane-3,7-dione-diphosphonic acid, which was synthesized at Jacobs University Bremen (Bremen, Germa-ny). On the working electrode modifier inflicted electrochemically. Applica-tion of the modifier helped to get a response from cholesterol. Cholesterol
