22. The Electronic Structure of Organic Molecular Materials : Theoretical and Spectroscopic Investigations
Abstract : In the present thesis the electronic properties of two organic molecules were studied by means of density functional theory (DFT) in connection to their possible applications in organic photovoltaics and molecular spintronics respectively.The first analysed system is the C60 derivative PCBM extensively used in polymer solar cells for the charge separation process.

23. Performance of Magnetorheological Rubber Materials
Abstract : Magnetorheological (MR) rubber materials are the solid analogue of magnetorheological fluids; i.e. their rheological properties can be controlled continously, rapidly, and reversibly by an applied magnetic field. READ MORE

25. Investigation of electrical and magnetic properties of nanoparticles and nanofibers with the aim to tailor material properties of nanocomposites
Abstract : Nanocomposites are the subject of interest in this study which can be explained by the factum that using building blocks with dimensions in the nanosize range makes it possible to design and create new materials which can satisfy several functions at the same time for many applications. The applications of interest in this study belong to the microwave frequency region and for that reason a number of materials were investigated to define their microwave absorbing properties.
