  2. 6. High-Capacity Cool Thermal Energy Storage for Peak Shaving - a Solution for Energy Challenges in the 21st century

    Author : Bo He; KTH; []
    Keywords : Comfort cooling; peak shaving; phase change materials PCM ; cool thermal energy storage; DSC; phase change temperature; the heat of fusion; phase equilibrium; phase diagram.;

    Abstract : Due to climatic change, increasing thermal loads inbuildings and rising living standards, comfort cooling inbuildings is becoming increasingly important and the demand forcomfort cooling is expanding very quickly around the world. Theincreased cooling demand results in a peak in electrical powerdemand during the hottest summer hours. READ MORE

  4. 7. Biological membrane interfaces involved in diseases : a biophysical study

    Author : Fredrick Lindström; Gerhard Gröbner; Dick Sandström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid-state NMR; DSC; Amyloid-beta peptide; Nociceptin; DMPC; DMPG; DDAB; peptide-lipid interaction; branched-chain fatty acid.; Biophysical chemistry; Biofysikalisk kemi;

    Abstract : Interactions between peptides and biological lipid membranes play a crucial role in many cellular processes such as in the mechanism behind Alzheimer’s disease where amyloid-beta peptide (Abeta)is thought to be a key component. The initial step of binding between a surface active peptide and its target membrane or membrane receptor can involve a non specific electrostatic association where positively charged amino acid residues and a negatively charged membrane surface interact.

  5. 8. Synthesis of Transition Metal Aluminides from Elemental Powder Mixtures

    Author : Hossein Sina; Materialteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminides; Intermetallics; Powder Metallurgy; Reactive Sintering; Combustion Synthesis; Thermal Analysis; DSC; Onset temperature; Phase evolution; SEM; EDS; XRD;

    Abstract : Structural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance.

  6. 9. Reactive Sintering of Cu-Al, Ni-Al and Ni-Ti Powder Mixtures

    Author : Hossein Sina; Materialteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; In-situ microscopy; DSC; Intermetallic; aluminide;

    Abstract : Intermetallic compounds are a distinct group of materials having attractive properties and wide applications. In the present work, the formation of intermetallic compounds from elemental components in Cu-Al, Ni-Al and Ni-Ti systems has been studied. Metallic powders were mixed in stoichiometric ratios corresponding to CuAl2, NiAl and NiTi. READ MORE

  7. 10. Interactions between Amylose, Native Potato, Hydrophobically Modified Potato and High Amylopectin Potato Starches

    Author : Fernando Ortega-Ojeda; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; DSC; rheology; starch; polymers;

    Abstract : The behaviour of different starches and their mixtures was investigated using several analysis techniques, i.e. small-deformation oscillatory measurements (rheological measurements), differential scanning calo-rimetry (DSC), light microscopy, and UV spectrophotometry (turbidi-metry).
