Stozhko Natalia Yurievna Doctor of Chemistry, Professor, Head of the Department of Physics and Chemistry of the Ural State University of Economics, Honorary Worker of Science and Technology of the Russian Federation. Graduated in 1977 from the Faculty of Chemistry of the Ural State University. In 1983 she defended the PhD thesis, in 2006 - the doctoral thesis on the topic: "Modified graphite-containing electrodes in stripping voltammetry". Research interests: Analytical chemistry, electrochemical methods of analysis, sensors, nanoparticles and nanomaterials, nanoeffects, electrochemistry of nanoparticles, antioxidants, "green" chemistry. Results of scientific activity: a methodology for creating a new generation of graphite-containing electrodes with high analytical characteristics is proposed. Electrochemical sensors with ultramicro- and nanostructured modifying layers, portable sensors with electrochemical sample preparation, 19 certified methods for laboratory, field and automatic flow-through-discrete analysis have been developed, two State Standart have been introduced to determine a number of elements in environmental objects, food products and foodstuffs raw material.
