    Abstract : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A.

  3. 22. Unveiling structural heterogeneities in aqueous solutions using dynamic light scattering

    University essay from Stockholms universitet/Fysikum

    Author : Oskar Eklund; [2021]
    Keywords : ;

    Abstract : To investigate the existence  of  molecular heterogeneties in mixtures of DMSO-water, the dynamics were measured with the method of dynamic light scattering (DLS). Three different compositions (20 mol %, 33 mol% and 60 mol%) were included in the study and measured at room temperature (295 K) and for one composition (33 mol %) also a temperature dependence (from 295 K down to 263 K) was measured.

  4. 23. EFFECT OF TUNING THE SURFACE OF LLZO PARTICLES ON THE PERFORMANCE OF CERAMIC –POLYMER COMPOSITE ELECTROLYTES

    University essay from Uppsala universitet/Strukturkemi; Uppsala universitet/Oorganisk kemi; Uppsala universitet/Fysikalisk kemi

    Author : Dagmawi Befikadu Gebrehiwot; [2021]
    Keywords : ;

    Abstract : Liquid based electrolytes are known to have safety issues and for their low volumetric energy densities to meet the future energy storage demand. Solid electrolytes based on ion conducting solid ceramic and solid polymer electrolytes are being studied and considered as an alternative to alleviate the issues with liquid electrolytes. READ MORE

  5. 24. The evaluation of preparation techniques for the measurements of hydrogen isotope ratios in ecology

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Kusal Weragama; [2021]
    Keywords : Deuterium; liquid water equilibration; steam equilibration; exchangeable H fraction; non-exchangeable H; Equilibrium fractionation factor; Isotopic soil fraction;

    Abstract : The stable isotope ratio of non-exchangeable hydrogen (δ2Hn) emerged as a promising new tool for source attribution in aquatic ecology, which can better discriminate between the organic matter sources. However, determining the absolute isotopic values is problematic due to the functional groups with hydrogen (H) that can easily exchange with the ambient water. READ MORE

  6. 25. Testbed Development for Non-invasive Intracranial Pressure Monitoring with a Microwave based Electromagnetic Skin Patch Sensor

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Sandra Palm; Hassan Saado; [2021]
    Keywords : Intracranial pressure; Artificial cerebrospinal fluid; Biomedical engineering; Microwave sensor;

    Abstract : Traumatic brain injuries (TBIs) are a major public health problem worldwide where the symptoms can be anything from mild concussion to severe swelling of the brain tissue. As a result of TBI the intracranial pressure (ICP) can elevate to pathological levels with severe consequences such as hypoxia, ischemia and brain hemorrhage. READ MORE
