  1. 21. Sustainable methods for the preparation of diverse Au(I) complexes

    Författare :Fredric Ingner; Lukasz Pilarski; Nicklas Selander; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : Over the last three decades, the role of Au(I) complexes has become increasingly important within medicinal chemistry, material applications and synthesis. Alas, their preparation remains reliant on harsh reaction conditions, hazardous solvents, exogenous additives and, often, high reaction temperatures. LÄS MER

  2. 22. Synthesis and characterization of two- and three-dimensional nanolaminated carbides

    Författare :Quanzheng Tao; Johanna Rosén; Per O A Persson; Amit Keren; Linköpings universitet; []

    Sammanfattning : This thesis is focused towards the synthesis and characterization of novel nanolaminated materials in primarily bulk (powder) form. Of particular interest is magnetic materials, or laminates that can be used as precursor for two-dimensional (2D) materials. LÄS MER

  3. 23. The flux of extraterrestrial spinels to Earth associated with He-3 anomalies in Cenozoic and Ordovician sediments

    Författare :Samuele Boschi; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Chromite; He-3 anomaly; Cenozoic; mid-Ordovician; asteroid breakup; ordinary chondrites; Popigai ejecta; iridium anomaly; Zircons; ice age;

    Sammanfattning : The main goal of this thesis is to reconstruct the flux of extraterrestrial matter to Earth in specific time intervals of our past in order to add an astronomical dimension to the understanding of Earth's history. To accomplish this, extraterrestrial chrome-spinel grains have been extracted and analysed. LÄS MER

  4. 24. Lime Mud Reburning. Properties and Quality of the Lime Produced

    Författare :Charlotta Hanson; Chalmers University of Technology; []
    Nyckelord :;

    Sammanfattning : It is of utmost importance that the white liquor used in the digester of a sulphate pulp mill is of high quality. The white liquor is prepared in the causticizing plant, through causticizing of the sodium carbonate in the green liquor. LÄS MER

  5. 25. Dynamic principles in craniofacial surgery. Expander elements in craniofacial surgery

    Författare :Fredrik Gewalli; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scaphocephaly; Brachycephaly; Dynamic cranioplasty; Pi-procedure; DCB; Expander elements; Distraction; Mental development; ICP; Cephalometry; Cephalic index;

    Sammanfattning : Lannelongue & Lane described strip removal of ossified skull sutures in craniosynostosis in the 1890s. More complex osteotomies with bone grafting were developed during the 1960s. Dynamic techniques, utilizing force to direct the growing brain for skull reshaping was introduced by Jane 1978 with the p-plasty for sagittal synostosis. LÄS MER
