  1. 6. The bentonite barrier : microstructural aspects on colloid filtration and radiation effects on bentonite colloid stability

    Författare :Michael Holmboe; Mats Jonsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry;

    Sammanfattning : In many countries a multi-barrier concept in a deep geological repository is planned for final disposal of nuclear waste. Many of these different concepts, for example the Swedish KBS-3 model, include an engineered barrier consisting of compacted bentonite. LÄS MER

  3. 7. Creating Ultrafast Biosensors for Neuroscience

    Författare :Yuanmo Wang; Chalmers tekniska högskola; []

    Sammanfattning : Neuronal communication is the basis for all our brain function and relies on regulated exocytosis, a cell function that involves release of quantal amounts of neurotransmitters into the gap space between interconnected neurons to serve as chemical signals. To study exocytosis, which is a fast process that occurs on the timescale of sub-milliseconds to milliseconds, a toolbox of analytical methods has been developed where the electrochemical based techniques offer quantitative and sufficient high temporal recording speed.

    Sammanfattning : Irritable bowel syndrome (IBS) is a complex disorder of gut-brain interactions. The diagnosis of IBS is based on subjective reporting of abdominal pain and altered bowel habits in the absence of any clinical alterations of the gut or other pathological conditions. LÄS MER

  5. 9. Tailored Reaction Media for the Synthesis of Subvalent Cluster Compounds

    Författare :Josefin Åkerstedt; Lars Kloo; Sven Lidin; Ulf Gedde; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Inorganic Chemistry;

    Sammanfattning : Different synthetic approaches and modifications to reaction media have been applied in order to find new routes to the synthesis of main-group clusters and transition metal compounds. The focus has been on the Group 15 element bismuth and the transition metal palladium. LÄS MER

  7. 10. Biomarkers for Better Understanding of the Pathophysiology and Treatment of Chronic Pain : Investigations of Human Biofluids

    Sammanfattning : Chronic pain affects 20 % of the global population, causes suffering, is difficult to treat, and constitutes a large economic burden for society. So far, the characterization of molecular mechanisms of chronic pain-like behaviors in animal models has not translated into effective treatments. LÄS MER
