  2. 1. Vapor phase deposition of WO and WC

    Author : Per Tägtström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; vapor deposition; ALE; CVD; tungsten oxide; epitaxy; nanocrystals; tungsten carbide; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : WO3 and WC are two compounds that are widely used for a number of different thin film applications. In this thesis, these compounds have been deposited using two different deposition methods: atomic layer epitaxy (ALE) and chemical vapor deposition (CVD). READ MORE

  4. 2. Chemical vapor deposition of hard coatings : Development of W(C,N) coatings for cemented carbide and TiN deposition on a CoCrFeNi substrate

    Author : Katalin Böőr; Mats Boman; Markku Leskelä; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : There is a constant need for cutting tool material development to be able to machine new materials and improve the metal cutting efficiency. Inserts of indexable cutting tools usually consist of WC-Co cemented carbide (cc) with μm thick layers of ceramic coatings. READ MORE

  5. 3. A Quantum Chemical Exploration of SiC Chemical Vapor Deposition

    Author : Pitsiri Sukkaew; Örjan Danielsson; Erik Janzén; Olle Kordina; Lars Ojamäe; Raymond A. Adomaitis; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : SiC is a wide bandgap semiconductor with many attractive properties. It hasattracted particular attentions in the areas of power and sensor devices as wellas biomedical and biosensor applications. This is owing to its properties suchas large bandgap, high breakdown electric field, high thermal conductivitiesand chemically robustness. READ MORE

  6. 4. Simulations of Silicon Carbide Chemical Vapor Deposition

    Author : Örjan Danielsson; Erik Janzén; Anne Henry; Michel Pons; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Most of the modern electronics technology is based on the semiconducting material silicon. The increasing demands for smaller electronic devices with improved performance at lower costs drive the conventional silicon technology to its limits. READ MORE

  7. 5. Analysis of carbon black oxidation

    Author : Soheil Soltani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diesel particulate filter DPF ; deconvolution; inverse problems; residence time distribution; computational fluid dynamics CFD ; kinetic modeling; transient kinetics;

    Abstract : Diesel engines are known to be a major source of a highly pollutant material known as particulate matter, PM, which is a strongly threatening agent to human health. Therefore, diesel particulate filters are used to reduce PM emissions by trapping soot. READ MORE
