  2. 21. Synthesis and Characterization of Amorphous Carbide-based Thin Films

    Author : Matilda Folkenant; Ulf Jansson; Erik Lewin; Paul Mayrhofer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous; coating; thin film; nanocomposite; sputter deposition; PVD; XPS; SEM; TEM; electrical properties; mechanical properties;

    Abstract : In this thesis, research on synthesis, structure and characterization of amorphous carbide-based thin films is presented. Crystalline and nanocomposite carbide films can exhibit properties such as high electrical conductivity, high hardness and low friction and wear. READ MORE

  5. 23. Carbon Nanotube Polymer Composites: Mechanical, Electrical and Photorefractive Properties

    Author : Liliana Licea Jimenez; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon nanotubes; electrical properties; photorefractive properties.; polymer matrix nanocomposites; mechanical properties;

    Abstract : Incorporation of carbon nanotubes (CNT) into polymers is attractive due to the generally good processability of polymers and unprecedented properties of nanotubes. In this work, preparation and matrix known earlier but not employed so-far for nanocomposites are studied towards enhanced mechanical and electrical performances. READ MORE

  6. 24. Synthesis and Characterization of Multifunctional Carbide- and Boride-based Thin Films

    Author : Nils Nedfors; Ulf Jansson; Witold Gulbinski; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thin film; coating; magnetron sputtering; nanocomposite; boride; carbide; electrical properties; mechanical properties; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : This thesis present research on synthesis, microstructure, and properties of carbide- and boride- based thin films. The films have been synthesized by dc magnetron sputtering, and their microstructures have been characterized mainly by X-ray photoelectron spectroscopy (XPS), X-ray diffraction, and transmission electron microscopy.

  7. 25. Advances in time–domain induced polarisation tomography : Data acquisition, processing and modelling

    Author : Per-Ivar Olsson; Teknisk geologi; []
    Keywords : Tomography; Signal–to–noise ratio; Waveform; Duty–Cycle; induced polarisation; Electrical properties;

    Abstract : What would you find below your feet – how do you find out? Perhaps you could look at a geological map, drill, or dig? That could work, but sometimes the maps are not detailed enough, and digging everywhere to find out is impractical. Imagine if you could develop a method that allows you to see straight through the ground, as x–rays through the body! To some extent, such methods already exist; you can for example send electric current into the ground that tells you what lies beneath when it returns. READ MORE
