  1. 1. Food and Packaging Interactions Affecting Food Quality

    Författare :Fredrik Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sorbed vegetable oil; oxygen transmission rate; food packaging; supercritical fluid extraction; inertness test; refillable PET bottles; permeability; aroma; interactions; sorption;

    Sammanfattning : Food and packaging interactions that may impair the food quality have been studied and methods to determine these interactions have been developed. An off-line supercritical fluid extraction method using carbon dioxide was developed and used to extract sorbed low molecular weight compounds from polymer films. LÄS MER

  3. 2. Technological Change in an International Industrial System

    Författare :Leif Linnskog; Ulf Johanson; Peter Söderbaum; Hans Hasselbladh; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology; technological change; industrial networks; business relationships; strategic intention; power; negotiations; social capital; coalitions; structural inertness; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi; Industriell ekonomi och organisation;

    Sammanfattning : Industrial systems resist change, more often, because heavy production facilities and industrial constructions are expensive and have long economic lives, but also because people tend to defend ingrained conceptions of how things are and how activities ought to be performed. Starting out from the question: “How does technological change come about in an international, industrial system?” the thesis investigates the interplay between technological, social, and economic factors.

  4. 3. Ohmic Contacts for High Temperature Integrated Circuits in Silicon Carbide

    Författare :Katarina Smedfors; Carl-Mikael Zetterling; Niklas Rorsman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : In electrical devices and integrated circuits, ohmic contacts are necessary and a prerequisite for the current transport over the metal-semiconductor junctions. At the same time, a desired property of the ohmic contacts is to not add resistance or in other way disturb the performance. LÄS MER

  5. 4. Liquid Exfoliation of Molybdenum Disulfide for Inkjet Printing

    Författare :Viviane Forsberg; Håkan Olin; Renyun Zhang; Magnus Hummelgård; Joakim Bäckström; Li Yang; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MoS2; Exfoliation; Inkjet Printing; 2D materials; Environmental Friendly; TMD; thin films; industrial printing; 2D inks; printed electronics; thin films carrier mobility; large-area electronics; graphene analogues; solar cells;

    Sammanfattning : Since the discovery of graphene, substantial effort has been put toward the synthesis and production of 2D materials. Developing scalable methods for the production of high-quality exfoliated nanosheets has proved a significant challenge. LÄS MER

  7. 5. Microfabrication of Optical Components in Synthetic Diamond : Infrared Optics for Applications  in Astronomy and Spectroscopy

    Författare :Ernesto Vargas Catalan; Mikael Karlsson; Thomas Schuelke; Uppsala universitet; []
    Nyckelord :Diamond; microfabrication; microoptics; astronomy; IR-spectroscopy; corongraph; waveguide;

    Sammanfattning : Infrared optics is a broad general term, relevant to a range of fields. The manufactured diamond optical components utilized within this thesis were applied to both astronomy, in which direct imaging of star system using large ground-based telescopes and diamond coronagraphs was performed, and in absorption spectroscopy probing solvents and proteins using a tuneable quantum cascade laser and diamond waveguides.
