  1. 1. Structural characterization of complex inorganic materials using solid-state NMR spectroscopy

    Author : Hua Guo; Ulrich Häusserman; Sven Lidin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solid-state NMR; materials characterization; inorganic materials; Calcium phosphate cements; bone-substitution materials; Mixed-anion compounds; perovskite; Oxyhydride materials; Oxynitride materials; Barium titanate; Strontium vanadate; oorganisk kemi; Inorganic Chemistry;

    Abstract : Over the past decades, advancements in technology have relied greatly on the development of new functional inorganic materials. Detailed structural characterization of these materials is key for the understanding and also prediction of chemical and physical properties. READ MORE

  2. 2. Effect of metal ion irradiation on hard coating synthesis by physical vapor deposition

    Author : Tun-Wei Hsu; Magnus Odén; Grzegorz Greczynski; Sven Ulrich; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The aim of this thesis is to understand and control how the ions in the plasma influence the film growth during thin film deposition processes. Two physical vapor deposition (PVD) techniques are investigated, namely magnetron sputtering and cathodic arc evaporation. READ MORE

  3. 3. Theoretical Routes for c-BN Thin Film Growth

    Author : Johan Karlsson; Karin Larsson; Sven Ulrich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cubic boron nitride; chemical vapor deposition; density functional theory; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : Cubic boron nitride (c-BN) has been in focus for several years due to its interesting properties. The possibility for large area chemical vapor deposition (CVD) is a requirement for the realization of these different properties in various applications. Unfortunately, there are at present severe problems in the CVD growth of c-BN. READ MORE

  5. 5. Defect-engineered (Ti,Al)N thin films

    Author : Isabella Citlalli Schramm Benítez; Frank Mücklich; Magnus Odén; Sven Ulrich; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the effect of point defects (nitrogen vacancies and interstitials) and multilayering ((Ti,Al)N/TiN) on the phase transformations in cathodic arc-evaporated cubic (Ti,Al)N thin films at elevated temperatures. Special attention is paid to the evolution of the beneficial spinodal decomposition into c-TiN and c-AlN, the detrimental formation of wurtzite AlN and the potential application as hard coating in cutting tools.
