  1. 16. Cerium Oxide Nanoparticles and Gadolinium Integration : Synthesis, Characterization and Biomedical Applications

    Författare :Peter Eriksson; Kajsa Uvdal; Caroline Brommesson; Xuanjun Zhang; Zhang-Jun Hu; Duncan Sutherland; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A challenging task, in the area of magnetic resonance imaging is to develop contrast enhancers with built-in antioxidant properties. Oxidative stress is considered to be involved in the onset and progression of several serious conditions such as Alzheimer’s and Parkinson’s disease, and the possibility to use cerium-contained nanoparticles to modulate such inflammatory response has gained a lot of interest lately.

  3. 17. Near field immobilization of selenium oxyanions

    Författare :Anders Puranen; Mats Jonsson; Christophe Jegou; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Se-79; Selenium; Immobilization; Redox; Iron; Corrosion; Palladium; Catalyst; Spent Nuclear Fuel; Repository; Nuclear chemistry; Kärnkemi;

    Sammanfattning : The topic of this doctoral thesis is the potential near field immobilization of the radionuclide 79Se after intrusion of groundwater into a spent nuclear fuel canister in a repository. 79Se is a non naturally occurring long lived selenium isotope formed as a result of fission in nuclear fuel.

  4. 18. ZnO and CuO Nanostructures: Low Temperature Growth, Characterization, their Optoelectronic and Sensing Applications

    Författare :Gul Amin; Magnus Willander; Omer Nour; Anastasios Travlos; Linköpings universitet; []
    Nyckelord :Zinc oxide; Copper II oxide; Nanostructures; Hydrothermal growth; Light emitting diodes.;

    Sammanfattning : One dimensional (1-D), zinc oxide (ZnO) and copper (II) oxide (CuO), nanostructures have great potential for applications in the fields of optoelectronic and sensor devices. Research on nanostructures is a fascinating field that has evolved during the last few years especially after the utilization of the hydrothermal growth method. LÄS MER

  5. 19. Cerebral Protection in Experimental Cardiopulmonary Resuscitation : With Special Reference to the Effects of Methylene Blue

    Författare :Adriana Miclescu; Lars Wiklund; Samar Basu; Jo Kramer-Johansen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac arrest; cardiopulmonary resuscitation; reperfusion injury; methylene blue; nitric oxide; nitric oxide synthases; blood-brain barrier; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi; Anaesthesiology;

    Sammanfattning : Although survival rates are increasing, brain injury continues to be a leading cause of death after cardiac arrest (CA). Permanent brain damage after CA is determined by limited tolerance to ischemia from CA and cardiopulmonary resuscitation (CPR), as well as the unique cerebral response to reperfusion after return of spontaneous circulation (ROSC).

  7. 20. Solution-Chemical Synthesis of Cobalt and Iron:Zinc Oxide Nanocomposite Films

    Författare :Ulrika Lagerqvist; Annika Pohl; Peter Svedlindh; Mikael Ottosson; Theodor Schneller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fe:Zn oxide; Co-CoO; Solution-chemical synthesis; Heat treatment parameters; Nanocomposite; Film; Multilayer; Phase ratio; Phase distribution; Exchange bias; Magnetism; Photocatalysis; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : The potentially most important challenges today are related to energy and the environment. New materials and methods are needed in order to, in a sustainable way, convert and store energy, reduce pollution, and clean the air and water from contaminations. LÄS MER
