  2. 16. Long acting local anaesthetics - a study in rats

    Author : Henrik Dyhre; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; in vivo and effect kinetics; Comparison of in vitro; Neuro toxicity; Infraorbital nerve block; Sciatic nerve block; Lipid depot formulation;

    Abstract : Local anaesthetics provide excellent pain relief after central and peripheral nerve blocks. However, in many clinical situations there is an insufficient duration of action to allow effective treatment of long-term pain with single injection techniques. This problem became the focus of the present studies. READ MORE

  4. 17. Investigations of the corrosion resistances of magnetron sputtered multicomponent materials : A study on high entropy alloys, high entropy sublattice ceramics, and metallic glasses

    Author : Aishwarya Srinath; Leif Nyholm; Ulf Jansson; Rebecka Lindblad; Bernard Normand; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Corrosion resistance; high entropy alloys; magnetron sputtering; thin films; protective coatings;

    Abstract : The corrosion resistances of sputter deposited AlCrNbYZrN, CrNbTiTaWC and TaNiSiC alloys were assessed in acidic and alkaline environments. Compositionally complex alloying strategies, and whether they produced coatings with superior corrosion resistances, were explored. READ MORE

  5. 18. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties

    Author : Hans Fredriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical resonance; Raman-spectrum; carbon; optical spectrum; HOPG; GC amorphous carbon; oxidation; Nanofabrication;

    Abstract : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.

  6. 19. Reducing Alkali Chloride-Induced High Temperature Corrosion by Sulphur Containing Additives – A Combined Laboratory and Field Study

    Author : Sofia Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sulphur; Stainless Steels; Additives; Biomass; Waste; High Temperature Corrosion; Alkali Chlorides; Co-combustion;

    Abstract : In order to achieve a more sustainable society renewable fuels such as biomass and waste are attractive alternatives to fossil fuels for power production. However, fireside corrosion is a serious concern in boilers combusting biomass or waste. The high corrosion rates are often linked to large amounts of alkali chlorides in the flue gas. READ MORE

  7. 20. Controlling the Pore Size and Morphology of Mesoporous Silica

    Author : Emma M. Johansson; Magnus Odén; José M. Cordoba; Niklas Hedin; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Mesoporous silica with a hexagonally ordered pore structure (SBA-15) has been synthesized. Through variations in the synthesis conditions several morphologies, such as fibers, sheets and separate rods, have been realized. READ MORE
