    Abstract : An environmentally sustainable production of electrical power is important for preserving the earth’s natural resources. In order to utilize this power as efficiently as possible, it is of great importance to minimize the losses, for example in sliding electrical contacts. READ MORE

  5. 3. Thermal conductivity of some metals under pressure

    Author : Bertil Sundqvist; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Although measurements of a wide variety of physical properties have been carried out under pressure during the last decades, data for thermal conductivity under pressure are sparse. This is especially so in the case of metals, where the experimental difficulties are very large. READ MORE

  6. 4. Density Functional Theory Studies of Small Supported Gold Clusters and Related Questions : What a Difference an Atom Makes

    Abstract : During the last decades the specific manipulation of matter on the (sub-) nanometer scale, also known as nanoscience, became possible by technologies such as the scanning tunneling microscope. Nanocatalysts, i.e. catalytic active structures of up to a few nanometers in size, belong to this rather new class of materials. READ MORE
