  2. 6. Experiments and Theoretical Modeling of Fullerene-like CNx and CPx Thin Film Structures

    Author : Andrej Furlan; Lars Hultman; Ulf Jansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : This thesis concerns the materials science of carbon-based fullerene-like structures as a basis for the improvement of the applicability of FL-CNx protective thin films. In particular, structural origins of mechanical properties of FL-CNx coatings and water adsorption on their surface were investigated, both of which are critical parameters for their application as, e.

  4. 7. Electrodeposition of Ag/Co and Au/Co compositionally modulated thin films and nanowire arrays

    Author : Sima Valizadeh; Per Møller; Linköpings universitet; []
    Keywords : ;

    Abstract : In the past decade, electrochemical synthesis of metallic nanowires within the pores of porous membranes have attracted considerable attention because of their special optical, electronic, and magnetic properties as well as potential for nanotechnological applications. The concept of using membranes as a template for fabrication of metallic nanowires by electrodeposition is considered as an alternative solution to overcome the difficulty of fabricating fibrils with very small diameters by lithographic methods.

  5. 8. Radio Studies of Circumnuclear Gas in Active Galaxies

    Author : Ylva Pihlström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; techniques: interferometry; galaxies: starbust; galaxies: active; galaxies: nuclei; radio lines: galaxies; techniques: high angular resolution;

    Abstract : In this thesis we have used radio interferometry in order to perform high resolution spectral line studies of circumnuclear gas in AGN and starburst galaxies. Amongst the studied objects is the Seyfert 2 NGC5793, for which we find the high opacity HI absorption to be consistent with a 50-100 pc radius atomic disk aligned with the host galaxy disk.

  6. 9. Deep photometry of galaxies : to see or not to see /Magnus Näslund

    Author : Magnus Näslund; Nils Bergvall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : The edge-on spiral galaxy NGC 4565 and the distant galaxy cluster MS2255.7+2039 have been studied at optical wavelengths with deep photometry using the 2.56 m Nordic Optical Telescope on La Palma.By careful data reductions we traced the surface brightness of NGC 4565 to faint levels.

  7. 10. Nanoplasmonic Structures for Bio/Chemo Sensing

    Author : Tomas Rindzevicius; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface-enhancement; biorecognition; nanostructures; surface plasmons; nanoholes.; biosensing;

    Abstract : Localized surface plasmon resonances (LSPR's) in noblemetal nanostructures are sensitive to refractive index changes close to the metal surface, and the LSPR's can therefore be utilized to sense molecular binding reactions. This thesis focuses on fundamental properties and proof-of-principle sensing studies of nanoplasmonic structures relevant for molecular detection. READ MORE
