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

    Author : Torbjörn Lindblom; Bengt Nygård; Sten-Eric Lindquist; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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. READ MORE

  4. 4. Calorimetric methods for the study of fungi on building materials

    Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fungal growth; fungal activity; ergosterol; humidity; temperature; calorespirometry; oxygen; mätmetoder; röta; svamp; byggmaterial; påväxt; kalorimetri; microcalorimetry; isothermal calorimetry; Fungi; building materials; mould; Serpula lacrymans; rot fungi;

    Abstract : The aim of this project is to study the fungal growth habits on building materials as a function of humidity, temperature and other environmental parameters. The method of calorimetry is used as a way to quantify fungal activity on building materials. READ MORE

  5. 5. A Microcalorimetric Study of Macrocyclic Complexes in Aqueous Solution

    Author : Magnus Stödeman; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Aqueous Solution; Calixarene; Cyclodextrin; Vaporization; Macrocyclic compounds; Microcalorimetry; Kemi;

    Abstract : The present work involves a microcalorimetric characterization of the interactions among macrocyclic compounds and aliphatic molecules in aqueous solution. The macrocyclic compounds used in the study are a-,b- and g-cyclodextrin and 25,26,27,28-tetrahydroxycalix[4]arene-5,11,17,23- tetrasulphonate. READ MORE
