    Sammanfattning : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. LÄS MER

  3. 2. Reactions in the System Nitro-cellulose/ Diphenylamine with Special Reference to the Formation of a Stabilizing Product Bonded to Nitro-cellulose

    Författare :Torbjörn Lindblom; Bengt Nygård; Sten-Eric Lindquist; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Nitro-cellulose; NC; Propellant; Stabilizer; Diphenylamine; DPA; Stability; Shelf-life; Chemometry; FTIR; HPLC; Microcalorimetry; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The methods HPLC, microcalorimetry and FTIR together with chemometry, provide good analytical tools to follow the degradation of nitro-cellulose.The degradation products formed from diphenylamine (DPA) during storage can be followed with HPLC. FTIR, together with chemometry, also gives the precision needed for safety control of propellants. LÄS MER

  4. 3. In Search of the Holy Grail of Photoelectrochemistry : A Study of Thin Film Electrodes for Solar Hydrogen Generation
