  1. 1. Mass-Transport through Interfaces

    Författare :Sofie Gårdebjer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; poly 3-hydroxybutyrate ; permeability; diffusion cells; poly lactide-co-glycolide acid ; mass-transport; polyethylene; poly lactic acid ; ethylene acrylic acid; interfaces; cellulose;

    Sammanfattning : Many of the products in our daily life consist of layered structures, where packaging materials and wound care products can be mentioned as examples. These structures often consist of different kind of polymeric materials and between these materials interfaces are formed. LÄS MER

  3. 2. Mass Transport via Thermoplasmonics

    Författare :Steven Jones; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : When a metallic nanoparticle is illuminated with light under resonant conditions, the free electron gas oscillates in such a way that substantial amplification of the local electric field amplitude is achieved – this is known as a plasmonic resonance. This resonance enhances both the optical scattering as well as absorption. LÄS MER

  4. 3. Mass Transport in Apple Tissue: Effects of Tissue Structure and Osmotic Processing Conditions

    Författare :Nikolaos Mavroudis; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; drying; porosity; shrinkage; cell vitality; apple structure; apple; osmotic processing; mass transport; mass transport mechanisms;

    Sammanfattning : Osmotic processing can be a very useful processing step in today’s food industry enabling the production of high quality natural food ingredients out of plant tissues. The maintenance of high product quality is quite product specific with regard to quality attributes. These attributes include fresh/like appearance, taste, texture and composition. LÄS MER

  5. 4. Diffusive Mass Transport of Ions in Wood

    Författare :Reddysuresh Kolavali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorption; wood; mass transport; impregnation;

    Sammanfattning : Understanding the conditions that control the mass transfer of various chemicals/ions in wood is of great importance when it is subjected to various processes. Homogeneous impregnation with chemicals/ions, for example, increases the uniformity of the treatments to which the wood is subjected, reduces reaction times and may increase the yield of the final products.

  7. 5. Overcoming the Mass Transport Limitations of Dye-Sensitised Solar Cells : Towards highly efficient and robust alternative redox mediator electrolyte DSSCs

    Författare :Roger Jiang; Gerrit Boschloo; Erik Johansson; Anders Hagfeldt; Frédéric Sauvage; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitised solar cell; dye-sensitized solar cell; photoelectrochemical cell; cobalt tris bipyridine ; mass transport; photocurrent transients;

    Sammanfattning : Dye-sensitised solar cells (DSSCs) have been subject to decadelong research interest, and may have some potential niche market applications. Recently, major advances in power conversion efficiencies have been achieved following the transition to cobalt polypyridine based redox mediators. LÄS MER
