  1. 1. Thermoelectric Ba8Ga16Ge30 clathrates for waste heat recovery

    Författare :Daniel Cederkrantz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal stability; substitution; thermal conductivity; Seebeck coefficient; electrical resistance; Clathrates; Ba8Ga16Ge30; waste heat recovery; semiconductors;

    Sammanfattning : The modern, highly industrialized, society of today requires huge amounts of energy to function. This has resulted in a heavy dependence on the very energy efficient fossil fuels, a source of energy which of course is not infinite and we are slowly approaching the day when oil runs out. LÄS MER

  3. 2. Laser Based Powder Bed Fusion of Plain Carbon and Low-Alloy Steels: Microstructure and Processability

    Författare :William Hearn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-Alloy Steel; Additive Manufacturing; Lack of Fusion Porosity; Laser Based Powder Bed Fusion; Plain Carbon Steel; Intrinsic Heat Treatment; Keyhole Porosity; Cold Cracking;

    Sammanfattning : Despite the prominence of laser based powder bed fusion (LB-PBF) as an additive manufacturing technique, the number of alloys that have been approved for the process remains limited. In traditional manufacturing, ferrous alloys are the most common alloy group, consisting primarily of plain carbon and low-alloy steels. LÄS MER

  4. 3. 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.

  5. 4. Aspects on wettability and surface composition of modified wood

    Författare :Lars-Elof Bryne; Ove Söderström; Charles R. Frihart; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wettability; contact angle; work of adhesion; Lewis acid-base; modified wood; Building engineering; Byggnadsteknik;

    Sammanfattning : Wood is often combined with other materials such as thermoplastics, adhesives and coatings. In general, combinations of wood and polymers especially in outdoor exposure have poor long-term durability. LÄS MER

  7. 5. Exploring the functionality of coconut proteins

    Författare :Borges Chambale; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coconut; coconut milk; extraction; proteins; emulsions; functional properties; denaturation; gels; yield stress; glass structure;

    Sammanfattning : At present, coconut proteins are discarded as a waste product by the coconut oil industry. If the range of applications of coconut proteins is to be expanded, their potential functionalities should be investigated. Emulsions and gels are of the greatest interest in food industry. LÄS MER
