  2. 1. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    Author : Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Keywords : Cement; Bruk; Betong; Jontransport; Fukttransport; Sorptionsisoterm; Tillsatsmaterial; Kiselstoft; Masugnsslagg; Ciment; Mortier; Béton; Transport ionique; Transport d humidité; Sorption de vapeur d eau; Additions minérales; Fumée de silice; Laitier de haut fourneau granulé moulu; Cement; Mortar; Concrete; Ion transport; moisture transport; Water vapor sorption; Supplementary cementitious materials SCMs ; Silica fume; Ground granulated blast furnace slag;

    Abstract : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. READ MORE

  4. 2. An Experimental and Theoretical Study of the Mass Transport in Lithium-Ion Battery Electrolytes

    Author : Andreas Nyman; Göran Lindbergh; Mårten Behm; Signe Kjelstrup; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium‐ion batteries; Electrolytes; Transport properties; Conductivity; Diffusion coefficients; Transport number; Maxwell-Stefan equation; Simulations; Mathematical analysis; Polarization; Hybrid electric vehicles; Litiumjonbatterier; Aprotiska elektrolyter; Transport egenskaper; Konduktivitet; Diffusion koefficienter; Transporttal; Maxwell-Stefans ekvation; Simuleringar; Matematisk analys; Polarisation; Elhybridfordon; Electrochemistry; Elektrokemi;

    Abstract : Lithium‐ion batteries are particularly suitable as energy storage solutions in high power applications, such as hybrid electric vehicles. It is generally considered that one of the processes that limit the power density for lithium‐ion batteries is the mass transport in the electrolyte. READ MORE

  5. 3. New Approaches to Studies of Paracellular Drug Transport in Intestinal Epithelial Cell Monolayers

    Author : Staffan Tavelin; Per Artursson; Staffan Tavelin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; intestinal epithelium; tight junctions; cell culture; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Studies of intestinal drug permeability have traditionally been performed in the colon-derived Caco-2 cell model. However, the permeability of these cell monolayers resembles that of the colon rather than that of the small intestine, which is the major site of drug absorption following oral administration.
