• Abstract

  This project proposes the growth of single crystals of novel type-I intermetallic clathrates by the self-fluz technique, especially in families based on germanium (Ge46) containing mixed acceptors (e.g. Ba8GaxAuyGe46-x-y) and also the introduction of trivalent rare earth ions as guests (e.g. Ba6La2Ga12Au2Ge32). We will investigate the structural, thermodynamic and transport properties of …

• Abstract

  In this work will be performed an exhaustive study of the behavior of magnetic nanoparticles diluted in matrices of different types of liquid crystals, especially lyotropic liquid crystals, and polymeric elastomers, as well as common liquids such as oil and water. The interest is to study and understand the influence of anisotropy of liquid crystals chemically different (and with differen…

• Abstract

  We propose to characterize novel single crystals of germanium-based clathrates with respect to their thermoelectric properties. We have synthesized several sets of such samples, which have the general formulae Ba8GayMzGe46-y-z (M = Au, Ag, Cu) and Ba8-xRxGayAgzGe46-y-z (R = La, Ce, Eu). The inclusion of rare earth elements is expected to improve their thermoelectric conversion efficiency,…

• Abstract

  This project proposes to extensively study of magnetorhelogic properties of liquid crystals doped with magnetic particles. Sets of lyotropic liquid crystals doped with magnetic particles (ferrolyotropics), will be prepared. These sets will have different compositions of liquid crystal and different size of magnetic particles, ranging from nano to micrometer scale. The samples will be char…
