  2. 1. Evaluation of Capillary Flow in Gels - The Liquid Uptake of Capillaries and Gelation Mechanisms in Alginate Gels

    Author : Johanna Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; alginate gel; capillary action; Capillary flow;

    Abstract : For centuries it has been known that wetting liquids penetrate porous materials if the pores are sufficiently small. In some cases the liquid penetration is desired, like in kitchen paper or diapers, in other systems the penetration should be minimised or avoided, like in water repellent textiles or paper printing.

  4. 2. Surface tension-driven flow in soft porous materials — An investigation of the mechanism of capillary flow in microchannels of hydrogels

    Author : Johanna Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting on soft materials; Capillary flow; alginate gel; capillary action;

    Abstract : Spontaneous spreading of liquids in porous materials is of great industrial relevance and occurs in, for example, diapers, fabrics, paper or paint. Often, it is necessary to manipulate the spreading rate of liquids to result in the desired mass transport, for example to soak up large liquid volumes, as in a diaper. READ MORE

    Abstract : Capillary-based platforms for diagnostics are popular for the point-of-care diagnostics market because of their low cost, easy fabrication, and easy operation. Lateral flow tests are an excellent example of capillary-based platforms for point-of-care diagnostics. READ MORE

  6. 4. Mechanisms of transendothelial and tissue transport in the peritoneum. Experimental studies on rat

    Author : Bert-Inge Rosengren; Njurmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nefrologi; Urologi; hyaluronan; interstitium; blood flow; rat; pore; inhibition; temperature; peritoneal dialysis; permeability; capillary; protein; passive; active; transport; transcytosis; vesicle; Urology; nephrology; small solute;

    Abstract : In the present thesis, the quantitative role of active transport (transcytosis) in bulk transvascular protein movement in vivo was evaluated. Using chemical transcytosis inhibition (N-ethylmaleimide (NEM) and filipin), we were able to show that NEM actually increases endothelial permeability to macromolecules, probably as a result of unspecific toxic action on endothelial cells.

  7. 5. Novel on-line mid infrared detection strategies in capillary electrophoretic systems

    Author : Malin Kölhed; Bo Karlberg; Sven P. Jacobsson; Andre' J. Sommer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; on-line hyphenation; mid infrared detection; capillary electrophoresis; FTIR; quantum cascade laser; aqueous samples; Analytical chemistry; Analytisk kemi;

    Abstract : Infrared absorption spectra can provide analytically useful information on a large variety of compounds, ranging from small ions to large biological molecules. In fact, all analytes that possess a dipole moment that changes during vibration are infrared-active. The infrared (IR) spectrum can be subdivided into far-, mid- and near- regions. READ MORE
