  2. 1. Microstructure and high temperature properties of Mo(Si,Al)2 - The effect of particle strengthening and alloying

    Author : Aina Edgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; particle strengthening; Mo Si; Al 2; oxidation; alloying; high temperature mechanical properties;

    Abstract : High temperature heating processes within the steel industries result in significant emissions of CO2, primarily due to the combustion of fossil fuels. Electrification of these processes, such as through the implementation of resistive heating elements, holds great promise for reducing emissions. READ MORE

  4. 2. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries

    Author : Torbjörn Gäfvert; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kärnfysik; Nuclear physics; zircon; ceramics industry; thorium; TIG welding; waterworks; calcium chloride; dicalcium phosphate; phosphate industry; non-nuclear industries; TENORM; Natural radioactivity; NORM;

    Abstract : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. READ MORE

  5. 3. Nanostructured Ceramics - Synthesis and Understanding

    Author : Farnaz Ghajeri; Wei Xia; Freddy Kleitz; Uppsala universitet; []
    Keywords : Material Science; Nanoporouse Silica; Calcium Phosphate; Synthesis; Characterization; Adsorption; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : During the last years, nanostructured ceramics have been favored for use in the industry due to their beneficial properties. For example, calcium phosphate ceramics with their biocompatible and bioactive characteristics are beneficial in biomedicine. READ MORE

  6. 4. Sense, Actuate and Survive : Ceramic Microsystems for High-Temperature Aerospace Applications

    Author : Peter Sturesson; Greger Thornell; Lena Klintberg; Peter Bull; Pelle Rangsten; Uppsala universitet; []

  7. 5. Characterization of some natural and synthetic materials with silicate structures

    Author : Edwin Escalera; Farid Akhtar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials; Materialteknik; Engineering Materials;

    Abstract : The present thesis deals with characterization of silicate structures with a determined morphology and structure such as ordered mesoporous silica and layered silicates. Mesoporous silica groups are amorphous solids exhibiting highly ordered pore structures with narrow pore size distributions and large surface areas. READ MORE
