  2. 1. Skin hydration - How water and osmolytes influence biophysical properties of stratum corneum

    Author : Sebastian Björklund; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stratum corneum; diffusive transport; permeability; flow-through cell; Franz cell; transdermal drug delivery; water activity; vapor pressure; osmotic gradient; relative humidity; ceramide; free fatty acid; cholesterol; keratin filaments; natural moisturizing factor NMF ; urea; glycerol; molecular mobility; 13C natural-abundance solid-state NMR; polarization transfer; isothermal calorimetry; impedance spectroscopy; X-ray diffraction;

    Abstract : The outermost layer of skin (i.e., the stratum corneum, SC) is the interface that separates the water-rich inside of the body from the relatively dry external environment. SC forms an effective permeability barrier, which has to be overcome in transdermal drug delivery. READ MORE

  4. 2. Inactivation, Cell Injury and Growth of Microorganisms Exposed to Pulsed Electric Fields Using a Continuous Process

    Author : Kristina Aronsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Leuconostoc mesenteroides; PEF; Listeria innocua; cell injury; flow-through treatment chamber; membrane permeabilization; post-processing growth; microbial inactivation; pulsed electric fields; Escherichia coli; Saccharomyces cerevisiae;

    Abstract : Pulsed electric fields (PEF) is a proven technology to inactivate microorganisms under non-thermal conditions. The PEF technology has a potential as a "quality friendly" alternative to traditional methods of food preservation. READ MORE

  5. 3. Experimental and Mathematical Study of Incompressible Fluid Flow through Ceramic Foam Filters

    Author : Shahin Akbarnejad; Ragnhild Elizabeth Aune; Pӓr Jönsson; Andreas Westermoen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Ceramic Foam Filters (CFFs) are widely used to filter solid particles and inclusions from molten metal in metal production, particularly in the aluminum industry. In general, the molten metal is poured on the top of a ceramic foam filter until it reaches a certain height, also known as metal head or gravity head. READ MORE

  6. 4. Collagen of the extracellular matrix. Functional and structural studies

    Author : Olof Olsson; Avdelningen för translationell cancerforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Collagen; Extra Cellular Matrix. TGF-beta; integrin αvβ6;

    Abstract : The cancer microenvironment has been attracting increasing attention as the realization of its importance for both disease treatment and malignant progression. Here the aim was to elucidate some of the effects and mechanisms of the tumor microenvironment related to the extracellular matrix (ECM). READ MORE

  7. 5. Miniaturised Bioanalytical Chemistry in Acoustically Levitated Droplets

    Author : Sabina Santesson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; protein crystallisation; affinity two-phase partitioning; single cell analysis; bioanalytical chemistry; airborne chemistry; levitated droplets; Miniaturisation; acoustic levitation;

    Abstract : Fuelled by the current demands of the biological sciences, there is today a growing interest in microscale analysis. Miniaturisation of analytical instruments has become a long-standing trend. Miniaturisation offers several advantages, including rapid separation times, high performance and throughput, reduced costs, etc. READ MORE
