  2. 1. Elastic Wave Propagation in Anisotropic Media. Application to Ultrasonic NDT

    Author : A. Jonas Niklasson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layered media; cylinders; cracks; integral equations; scattering; nondestructive testing; elastic waves; ultrasonics; transducers; anisotropy;

    Abstract : The subject of this thesis is elastic wave propagation in anisotropic materials with application to ultrasonic nondestructive testing (NDT). The first part of the thesis is concerned with modeling of ultrasonic transducers and wave propagation in anisotropic materials in general. First, a scalar 2-D case is considered. READ MORE

    Abstract : Vanadium dioxide is a well-known thermochromic material, whose optical properties can be varied reversibly in response to fluctuation of temperature. It is attractive in various fields due to its unique properties as well as its prospective applications. READ MORE

  7. 5. Optical Absorption and Electrical Conductivity in Lithium Intercalated Amorphous Tungsten Oxide Films

    Author : Lars Berggren; Gunnar A. Niklasson; Ola Hunderi; Uppsala universitet; []
    Keywords : Technology; Lithium intercalation; amorphous; tungsten-oxide; sputtered films; optical absorption; polaron radius.; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Optical and electrical properties of electrochemically lithium ion intercalated thin films of x-ray amorphous tungsten oxide made by magnetron sputtering on glass substrates coated with a thin layer of conductive tin doped indium oxide, have been studied. The composition and the density of the films were characterized by the ion beam analysis methods Rutherford Backscattering Spectroscopy and Elastic Recoil Detection Analysis. READ MORE
