  1. 1. Cereal Proteins. Interfacial and Physicochemical Properties

    Detta är en avhandling från Food Technology, Lund University

    Författare :Lars Wannerberger; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; monolayer; Langmuir-Blodgett deposition; interaction; interfacial properties; adsorption; secalin; Wheat proteins; gliadin;

    Sammanfattning : The main theme of this thesis is the interfacial properties of cereal proteins from wheat and rye. Some aspects of dough bulk properties are also included. The proteins studied are of interest for the stabilisation of gas cells and the mechanism of gas retention, and the rheological properties of a bread dough. LÄS MER

  2. 2. Poly(Ethylene Oxide) Based Bottle-Brush Polymers and their Interaction with the Anionic Surfactant Sodium Dodecyl Sulphate Solution and Interfacial Properties

    Detta är en avhandling från Stockholm : KTH

    Författare :Joseph Iruthayaraj; KTH.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEO brush polymers; brush polymers; PEO; poly ethylene oxide ; polymer-surfactant; sodium dodecyl sulphate SDS ; Ellipsomtery; PEO-SDS interactions; NATURAL SCIENCES Chemistry Physical chemistry Surface and colloid chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Yt- och kolloidkemi;

    Sammanfattning : The aim of this thesis work is to study the physico-chemical properties of poly(ethylene oxide), PEO, based brush polymers both in solution and at solid/aqueous interfaces. The importance of studying the surface properties of brush polymers can be related to a broad spectrum of interfacial-related applications such as colloidal stability, lubrication, detergency, protein repellency to name a few.

  3. 3. Investigations of thermophysical properties of slags with focus on slag-metal interface

    Detta är en avhandling från Stockholm : KTH

    Författare :Luckman Muhmood; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slags; density; diffusivity; sessile drop; interfacial velocity; interfacial viscosity; interfacial dilatational modulus; interfacial shear viscosity; TECHNOLOGY Chemical engineering Metallurgical process and manufacturing engineering Metallurgical process engineering; TEKNIKVETENSKAP Kemiteknik Metallurgisk process- och produktionsteknik Metallurgisk processteknik;

    Sammanfattning : The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. LÄS MER

  5. 5. Calcium aluminate cement as dental restorative Mechanical properties and clinical durability

    Detta är en avhandling från Umeå : Umeå universitet. Institutionen för odontologi

    Författare :Karin Sunnegårdh-Grönberg; Umeå universitet.; [2004]
    Nyckelord :mechanical properties; clinical; restorations; ceramic; cement; resin composite; adaptation; SEM; odontologi; Odontology;

    Sammanfattning : In 1995, the Swedish government recommended the discontinuation of amalgam as restorative in paediatric dentistry. Because the mercury content in amalgam constitutes an environmental hazard, its use has declined. LÄS MER
