Martsinovich, Natalia - University of Sheffield

个人简介

Dr Natalia Martsinovich obtained her first degree in Chemistry from the Belarusian State University in 2000. She then obtained a PhD in Theoretical Chemistry from the University of Sussex in 2005, where she also worked as a temporary Lecturer in Physical Chemistry in 2003-04. She was a postdoctoral researcher in the Department of Physics at King’s College London (2004-08), and in the Department of Chemistry at the University of Warwick (2008-13). In 2013 she was appointed Lecturer at the University of Sheffield.

研究领域

My research is focussed on studying the properties of surface-adsorbate interfaces and processes taking place at these interfaces. Important applications include photovoltaics and photocatalysis. I use a range of theoretical methods, mainly density-functional theory, and also charge transfer theory and molecular mechanics. Photovoltaics Photovoltaics uses solar cells to convert solar energy into electricity. Several types of solar cells have been developed; the current market leaders – silicon solar cells – are efficient but expensive. Solar cells based on organic molecules, such as dye-sensitised solar cells (DSSC) are cheap and are currently a subject of active research. The efficiencies of these solar cells are controlled by light absorption properties and rates of charge transfer within the solar cell. In my recent project in Warwick, I developed a model for calculating the rates of charge transfer between semiconductors and adsorbed dyes, to identify semiconductor-dye interfaces which lead to efficient DSSC. Photocatalysis Photocatalysis is a process which converts the energy of the Sun into the energy of chemicals. One of the most important photocatalytic processes is the splitting of water into molecular oxygen and hydrogen. This process is particularly interesting because hydrogen is a promising fuel and an environmentally friendly "clean" alternative to petrol. I will study semiconductor metal oxides (TiO2, WO3, Fe2O3 etc.) and their interfaces with water and organic molecules to obtain the rates of charge transfer in photocatalytic oxidation and reduction reactions. Molecular self-assembly Another area of interest is molecular self-assembly – the process whereby molecules assembly into ordered patterns, thanks to specific interactions between these molecules. These ordered structures have the potential to be used as circuits in molecular electronics. I have modelled the structures and dynamics of two-dimensional assemblies of organic molecules (e.g. carboxylic acids) on graphite, in collaboration with the experimental group of M. Lackinger in Munich.
