  4. 2. Modification of Float Glass Surfaces by Ion Exchange

    Author : Stefan Karlsson; Bo Jonson; Helmut Schaeffer; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ion exchange; float glass; surface modification; surface colour; flexural strength; Glasteknologi; Glass Technology;

    Abstract : Glass is a common material in each person’s life, e.g. drinking vessels, windows, displays, insulation and optical fibres. By modifying the glass surface it is possible to change the performance of the entire glass object, generally known as Surface Engineering. READ MORE

  5. 3. Continuous electropermutation using ion-exchange textile

    Author : Carl-Ola Danielsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ion-exchange textile; ion-exchange membrane; electopermutation; electroextraction; Mechanical manufacturing engineering; Mekanisk tillverkningsteknik;

    Abstract : Increased levels of nitrate in ground water has made many wells unsuitable as sources for drinking water. In this thesis an ion-exchange assisted electromembrane process, suitable for nitrate removal, is investigated both theoretically and experimentally. READ MORE

  6. 4. Land surface heat exchange over snow and frozen soil

    Author : David Gustafsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface energy balance; Snow; Boreal forest; SVAT models; Eddy-correlation Measurements; Latent heat flux; Sensible heat flux; Net radiation; Soil temperature; Aerodynamic roughness; Surface resistance; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Abstract : The energy exchange in the soil-snow-vegetation-atmospheresystem was studied to improve the quantitative knowledge of thegoverning processes. The lack of such knowledge contributes tothe uncertainty in the applicability of many existing modelsindependent of the temporal or spatial scale. READ MORE
