  2. 6. Photon stimulated CVD of amorphous carbon thin films : By Mikael Lindstram

    Author : Mikael Lindstam; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; photolysis; thermal activation; CVD; amorphous carbon; modelling; kinetics; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Amorphous carbon has attracted much interest for several decades now because of its complex crystal structure and microstructure. Depending on the carbon sp2/sp3 bonding ratio, these materials yield a broad spectrum of useful properties; which can be tailored for specific applications. READ MORE

  4. 7. Microstructural investigation of CVD TiAlN, TiN and WN coatings

    Author : Ren Qiu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEM; XEDS; TiN; SEM; APT; TiAlN; coating growth; EBSD; WN; CVD;

    Abstract : High speed machining of workpiece materials puts extreme thermal and pressure loads onto the cutting tool inserts, which thus must possess both high hardness and good toughness. Nowadays, most cutting tools are made of cemented carbide substrates that are coated with wear-resistant coatings. READ MORE

  5. 8. Microstructure and plastic deformation of textured CVD alumina coatings

    Author : Siamak Shoja; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; α-Al2O3; Texture; Coatings; TKD; Plastic deformation; Deformation mechanisms; Electron microscopy; CVD;

    Abstract : It is known that the wear performance of α-alumina coatings produced by chemical vapor deposition (CVD) is significantly influenced by the type and degree of texture. However, the main reasons behind this behavior are not fully understood. This thesis contains studies of two related topics for increasing the understanding of α-alumina coatings. READ MORE

  6. 9. CVD solutions for new directions in SiC and GaN epitaxy

    Author : Xun Li; Urban Forsberg; Erik Janzén; Henrik Pedersen; Sebastian Lourdudoss; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CVD; SiC; GaN; epitaxy;

    Abstract : This thesis aims to develop a chemical vapor deposition (CVD) process for the new directions in both silicon carbon (SiC) and gallium nitride (GaN) epitaxial growth. The properties of the grown epitaxial layers are investigated in detail in order to have a deep understanding. READ MORE

  7. 10. Genetic predisposition to salt sensitivity and cardiovascular disease

    Author : Jonas Dahlberg; Kardiovaskulär forskning - hypertoni; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NEDD4L; SGK-1; CVD; ischemic stroke; genetics; CVD deaths; myopcardial infarction;

    Abstract : Abstract The average amount of salt ingested is about 10 grams daily compared to less than one gram in pre-historic life. Salt, althought somewhat debated, is considered a risk factor for elevated blood pressure and end organ damage beyond the blood pressure effect. READ MORE
