  1. 1. Carbon Nitride Characterization and Protein Interactions

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Torun Berlind; Hans Arwin; Pentti Tengvall; Hans Hultman; Thomas E. Tiwald; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis concerns synthesis and characterization of carbon-based materials and theinvestigation of the possible use, of a selection of these materials, in biomedicalapplications. Protein adsorption and blood plasma tests were used for this purposeutilizing a surface sensitive technique called spectroscopic ellipsometry. READ MORE

  2. 2. Functional properties of silicon nitride based materials for joint applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Luimar N. Corrêa Filho; Cecilia Persson; Julia Shelton; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon nitride; Coatings; Wear; Joint replacements; HiPIMS; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Total hip and total knee replacements are generally successful procedures for patients suffering with pain due to bone fracture or diseases affecting the joints. However, the materials that are commonly used still have limitations. In particular, corrosion products and wear debris may give rise to negative body reactions. READ MORE

  3. 3. The silicon nitride reaction-bonding process

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Bingqiang Lei; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : The so called Reaction-Bonded Silicon Nitride (RBSN) materials are usually produced through the chemical reaction of silicon powder compacts in a nitriding atmosphere. This nitriding reaction is strongly exothermic and much heat is generated, which may cause to overheating, even melting of the powder compacts so to hinder the further reaction due to the reduction of specific area of the powder compacts, especially when the nitridation involves a rather large mass of silicon.

  5. 5. Integrated Nonlinear Optics in Silicon Nitride Waveguides

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Clemens Krückel; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; integrated optics devices; nonlinear optics materials; four-wave mixing; nonlinear optical signal processing; wavelength conversion devices; nanostructure fabrication;

    Abstract : Current nanofabrication techniques allow patterning of optical waveguides with submicron cores. This results in strong confinement of light, which leads to high optical intensities. READ MORE
