    Sammanfattning : The depletion of oil reserves and the increasingly stringent European Union regulation of air pollution have forced researchers and manufacturers to search for cleaner and sustainable substitutes to petroleum‐based transportation fuels. Biofuels like small aliphatic alcohols are of increasing interest as alternatives to fossil fuels, as they offer long‐term fuel‐source regenerability. LÄS MER

  4. 3. Synthesis and properties of substituted Hg-based superconductors

    Författare :Dmitriy A. Pavlov; Ingrid Bryntse; Lauri Niinistö; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hg-based cuprate superconductors; synthesis and structure determination; LiF flux; oxyfluorides; irrevrsibility line; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : This thesis is focused on studies of substituted Hg-based superconducting copper oxides ((Hg1-xMx)Ba2Can-1CunO2n+2+δ). These compounds are promising objects of investigation, not only from a fundamental point of view but also because of their high values of superconducting transition temperature (Tc) and irreversibility field (Hirr).
