The LaAlO3/SrTiO3 interface provides an intriguing 2-dimensional electron system in which the coexistence of superconductivity and magnetism has been observed. This chapter presents preliminary results of ongoing angular dependent torque magnetometry measurements on SrTiO3-LaAlO3 heterostructures at different magnetic fields and temperatures. The authors have calculated the lattice thermal conductivity in layered oxide thermoelectric (TE) materials using perturbed molecular dynamics methods and tried to reveal the mechanisms of thermal conduction, thereby building up a strategy to control it. In order to achieve the next generation of nanometer sized electronic devices a detailed understanding and control of electrical transport is essential. The chapter reports on electronic transport measurements of biphenylpropanethiol (BP3) capped gold nanoparticles (AuNPs) with a diameter of 4 nm used as functional units. Controlled Vocabulary Terms electronic structure; lattice dynamics; magnetic fields; superconductivity
