  2. 16. Integrated biomechanical, electronic and topographic characterization of titanium dental implants

    Author : Johanna Löberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface roughness parameters; 3D-SEM; AFM; Interfacial shear strength; Impedance spectroscopy; Cyclic voltammetry; SBF; MG-63; TiO2-nanoparticles;

    Abstract : Titanium dental implants are medical devices used to restore the function entailed with the loss of one or several teeth. To obtain successful function over long periods, the dental implants must be sufficiently anchored in the bone to withstand the forces induced by for example chewing. READ MORE

  4. 17. Alkali Metal Aurivillius Phases Structure and Electrical Properties

    Author : Stefan Borg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; neutron powder diffraction; phase transition; X-ray powder diffraction; Aurivillius phases; impedance spectroscopy; Curie temperature; electron microscopy;

    Abstract : The quest for new materials is crucial for the development of smaller and more efficient electronic components. Aurivillius phases have recently received considerable attention due to their wide-ranging properties and are considered promising candidates in e.g. memory devices, microwave filters and fuel cells.

  5. 18. 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

  6. 19. State-of-Health Estimation of Li-ion Batteries: Ageing Models

    Author : Jens Groot; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; State-of-health; lithium-ion battery; EV; PHEV; cycle life test; impedance spectroscopy; DVA; battery testing; ICA; battery model; HEV;

    Abstract : Significant research efforts are being made to understand, and ultimately mitigate, thedegradation of Li-ion batteries upon usage. Currently, battery ageing models are used inorder to optimise the battery usage and to achieve robust battery solutions. READ MORE

  7. 20. Near infrared and skin impedance spectroscopic in vivo measurements on human skin : development of a diagnostic tool for skin cancer

    Author : Ida Bodén; Peter Naredi; Britta Lindholm-Sethson; Paul Geladi; Bo Karlberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Combined probe head; Malignant melanoma; diagnosis; NIR; Skin impedance; PCA; PLS-DA; kirurgi; Surgery;

    Abstract : Every year approximately 2800 Swedes are diagnosed with malignant melanoma, the form of cancer that is most rapidly increasing in incidence in the Western world. The earlier we can identify and diagnose a malignant melanoma, the better is the prognosis. READ MORE
