  1. 11. The mechanisms controlling heat and mass transfer on frying of beefburgers

    Författare :Bea Kovácsné Oroszvári; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; permeability; porosity; contraction; frying; beefburger; heat and mass transfer;

    Sammanfattning : The aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied.

  3. 12. The effect of microstructural features, defects and surface quality on the fatigue performance in Al-Si-Mg Cast alloys

    Författare :Toni Bogdanoff; Ehsan Ghassemali; Salem Seifeddine; Anders E.W. Jarfors; Ru Peng; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum-Silicon alloys; defects; material characterization; fatigue performance; digital image correlation;

    Sammanfattning : Global warming is driving industry to manufacture lighter components to reduce carbon dioxide (CO2) emissions. Promising candidates for achieving this are aluminium-silicon (Al-Si) cast alloys, which offer a high weight-to-strength ratio, excellent corrosion resistance, and good castability. LÄS MER

  4. 13. Synthesis of nanoporous Ca3Co4O9 thin films for flexible thermoelectrics

    Författare :Binbin Xin; Per Eklund; Biplab Paul; Niclas Solin; Tomas Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : During energy generation, transportation and usage, large amounts of energy are lost as waste heat. With increasing energy consumption and environmental issues, exploiting this waste heat has drawn extensive attention. LÄS MER

  5. 14. Coated Surfaces for Inkjet-Printed Conductors

    Författare :Thomas Öhlund; Hans-Erik Nilsson; Jonas Örtegren; Jouko Peltonen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet; Nanoparticles; Paper; Flexible substrates; Sintering; Printed Electronics; Functional Printing;

    Sammanfattning : In this thesis, a number of commercially available paper substrates of various types are characterized and their characteristics related to the performance of inkjet-printed conductors using silver nanoparticle ink. The evaluated performance variables are electrical conductivity as well as the minimum achievable conductor width and the edge raggedness. LÄS MER

  7. 15. Electrochemical Reactions of Quinones at Conducting Polymer Electrodes

    Författare :Canyan Che; Xavier Crispin; Mikhail Vagin; Magnus Jonsson; Viktor Gueskine; Mieczyslaw Lapkowski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Proton-coupled multielectron transfer reactions are of great abundance in Nature. In particular, two-proton-two-electron transfers in quinone/hydroquinone redox couples are behind oxidative phosphorylation (ADP-to-ATP) and photosystem II. LÄS MER
