  1. 1. Diffusion of Radionuclides in Bentonite Clay Laboratory and in sity Studies

    Detta är en avhandling från Stockholm : KTH

    Författare :Mats Jansson; KTH.; [2002]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; cation; anion; diffusion; sorption; cobalt; caesium; strontium; iodide; pertechnetate; surface diffusion; in situ; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : This thesis deals with the diffusion of ions in compactedbentonite clay. Laboratory experiments were performed toexamine in detail different processes that affect thediffusion. To demonstrate that the results obtained from thelaboratory investigations are valid under in situ conditions,two different kinds of in situ experiments were performed. LÄS MER

    Sammanfattning : This thesis is a summary and discussion of eight papers dealing with failures and structural aspects of Ni-Cd industrial pocket plate batteries, applications of voltammetry in adsorption studies on goethite (a-FeOOH) surfaces and synthesis and characterisation of nanostructured carbons. The work consists of different areas of chemistry; electrochemistry, structural chemistry and solution chemistry. LÄS MER

  3. 3. Further characterisation and applications of the diffusive gradients in thin films technique In situ measurements of anions and cations in environmental waters

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Helene Österlund; Luleå tekniska universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : As both the toxicity and the mobility of trace elements are related to chemical forms present, robust methods for element speciation analysis are of great interest. During the last 15 years, hundreds of scientific articles have been published on the development and applications of the diffusive gradients in thin films (DGT) passive sampling technique. LÄS MER

  4. 4. Bio-based C-3 Platform Chemical: Biotechnological Production and -Conversion of 3-Hydroxypropionaldehyde

    Detta är en avhandling från Lund University

    Författare :Roya Rezaei; Lund University.; Lunds universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactobacillus reuteri; 3-hydroxypropionic acid; biotransformation; Glycerol; 3-hydroxypropionaldehyde; In situ complexation;

    Sammanfattning : Demands for efficient, greener, economical and sustainable production of chemicals, materials and energy have led to development of industrial biotechnology as a key technology area to provide such products from bio-based raw materials from agricultural-, forestry- and related industrial residues and by-products. For the bio-based industry, it is essential to develop a number of building blocks or platform chemicals for C2-C6 chemicals and even aromatic chemicals. LÄS MER

  5. 5. The Mussel Adhesive Protein (Mefp-1) A GREEN Corrosion Inhibitor

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Fan Zhang; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon steel; mussel adhesive protein; Mefp-1; inhibitor; adsorption; film forming; complexation; cross-linking; ceria nanoparticle; composite film; EIS; AFM; QCM-D; ATR-FTIR; Confocal Raman Micro-spectroscopy; DFT calculation;

    Sammanfattning : Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. LÄS MER
