  1. 21. Carbon Dioxide: The Unknown Factor in the Atmospheric Corrosion of Light Metals. A Laboratory Study

    Författare :Daniel Bengtsson Blücher; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SO2; temperature; CO2; atmospheric corrosion; magnesium; NO2; aluminum alloys; NaCl; O3; Mg-Al alloys;

    Sammanfattning : The atmospheric corrosion of Al and Mg-Al alloys was investigated using controlled air in the laboratory. The effects of CO2, temperature, NaCl, relative humidity, SO2, NO2 and O3 on corrosion rate and corrosion product composition were examined. LÄS MER

  3. 22. Alpha-radioimmunotherapy with At-211: Evaluations and imaging on normal tissues and tumors

    Författare :Tom Bäck; Göteborgs universitet; []
    Nyckelord :radioimmunotherapy; astatine; RBE; renal function; GFR; imaging; targeted radiotherapy; alpha-RIT;

    Sammanfattning : Alpha-radioimmunotherapy (alpha-RIT) is an internal conformal radiotherapy at the cellular level using alpha-particle emitting radionuclides. Alpha-particles have a very short range in tissues (... LÄS MER

  4. 23. A journey towards complete structure determination of zeolites by electron crystallography methods

    Författare :Elina Kapaca; Xiaodong Zou; Philippe Boullay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; Zeolites; Structure determination; Rotation electron diffraction; Continuous rotation electron diffraction; Disorder; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Electron crystallography has recently become very successful for structural studies of materials with sub-micrometer sized crystals. In this thesis two major techniques have been applied for structure elucidation – 3-dimensional electron diffraction (3D ED) and high-resolution transmission electron microscopy (HRTEM) imaging.

  5. 24. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass

    Författare :Anna Strandberg; Markus Broström; Rainer Backman; Christoffer Boman; Maria Zevenhoven; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Char conversion; pyrolysis; devolatilization; ash transformation; biomass; fuel characterization; fuel composition; ash composition; silicate formation; carbonate formation; thermogravimetric analysis; micro-tomography;

    Sammanfattning : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. LÄS MER

  7. 25. Detailed structure features from 3D electron diffraction : Heteroatoms, framework disorders, and guest species in zeolites

    Författare :Jungyoun Cho; Xiaodong Zou; Tom Willhammar; Miguel Camblor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; zeolite; transmission electron microscope; structure determination; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : 3D electron diffraction (3D ED) has evolved as a powerful method for ab initio structure determination from sub micrometer-sized crystals. It can be used to elucidate the arrangement of atoms in crystalline materials and to provide insights into the laws of nature that govern the properties of matter. LÄS MER
