  2. 6. 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. 7. 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

  5. 8. Active cellular forces in variable mechanical microenvironments

    Author : Adele Khavari; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traction force; Gradient substrate; Alginate 3D culture; Durotaxis; mechanics;

    Abstract : Our bodies are immensely complex structures, with various systems, organs, and processes that are not only biochemically driven, but strongly dependent on physical mechanics.  At the heart of all these processes are cells, which must generate forces to adhere, spread, differentiate, grow, and move.

  6. 9. Experimental therapeutic angiogenesis after myocardial infarction : efficacy of different angiogenic factors and delivery methods

    Author : Xiaojin Hao; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Angiogenesis; arteriogenesis; apoptosis; myocardial infarction; VEGF-A165; bFGF; PDGF-BB; adenovirus; plasmid; alginate;

    Abstract : Angiogenesis, the stimulation of vessel growth, is a promising therapy in ischemic heart disease. A wealth of evidence has shown that several growth factors can induce neovascularization in ischemic models. However, the optimal application of growth factors and delivery method requires further exploration. READ MORE

  7. 10. Validation of mild cooking processes with target of Listeria monocytogenes inactivation to ensure food safety

    Author : Sonja Karin Grönqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the use of Time Temperature Integrators (TTIs) to validate industrial cooking processes aimed to achieve a 6 logarithmic inactivation of Listeria monocytogenes, equal to a heat load of 2 min at 70 °C (P707.5 = 2) . To produce microbiological TTIs, live cells of L. monocytogenes were crossbound in alginate beads. READ MORE
