  2. 16. Interfacial Properties of Film Forming Proteins and their Layer-by-Layer Assembly with Nanoparticles

    Author : Olga Krivosheeva; Per Claesson; Thomas Arnebrant; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein adsorption; mussel adhesive protein; Mefp-1; hydrophobins; HFBI; HFBII; adsorption kinetics; layer-by-layer; stability; cross-linking; zeta-potential; dual polarization interferometry; quartz crystal microbalances;

    Abstract :  The aim of this thesis work was to investigate the interfacial properties of film forming proteins, stability of the layers created by them, and their interactions with nanoparticles. Mussel adhesive protein (Mefp-1) and hydrophobins (HFBI and HFBII) were the three main proteins used. READ MORE

  4. 17. Assembly and adhesive properties of curli : a stationary phase-specific surface organelle in Gram-negative enteric bacteria

    Author : Mårten Hammar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Escherichia colilcurli fimbriae csgstarvation;

    Abstract : The natural environments of bacteria are most often characterized by suboptimal conditions for growth, e. g., limited supply of nutrients. Consequently, periods of dormancy or negligible growth are the rule rather than the exception. READ MORE

  5. 18. Colliding asperities : a tribological event on micro scale

    Author : Shaojie Kang; Stefan Björklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : In order to predict and optimize energy efficiency, fuel consumption and service life, friction and wear need to be predetermined with higher accuracy than what is possible today. This prediction and optimization is crucial for the development of sustainable mechanical components and systems with excellent environmental performance. READ MORE

  6. 19. The influence of tool steel microstructure on galling

    Author : Patrik Karlsson; Pavel Krakhmalev; Anders Gåård; Bojan Podgornik; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galling; Microstructure; Material transfer; Tool steel; Stainless steel; Metall transfer; Materialteknik; Materials Engineering;

    Abstract : In sheet metal forming (SMF) of materials such as stainless steels there is a major problem with transfer and accumulation of sheet material to the metal forming tool surface. The problem is known as galling; a sort of severe adhesive wear, which results in severe scratching of produced parts. READ MORE

  7. 20. Modelling of wear and galling in press hardening simulations

    Author : Liang Deng; Mats Oldenburg; Karl Nielsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Implementation of press hardened parts in automobile responses to the requirement of reduced carbon dioxide emission because the press hardened part has very high ratio of strength to weight. Furthermore, ultra high-strength steels (press hardened parts) increases the vehicle safety. READ MORE
