  2. 1. Nanostructured carbon materials prepared by hole-mask colloidal lithography

    Author : Hans Fredriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HOPG; GC; Colloidal Lithography; Oxygen; RIE; Nanofabrication;

    Abstract : Research and development of nanofabrication methods can be motivated both formanufacturing of commercially available products like micro electronic componentsand for development of model systems for fundamental and applied science. Thefabrication process developed during this work, hole-mask colloidal lithography(HCL), is primarily oriented towards the latter two, specifically for research in thefields of catalysis, nanoparticle plasmons, and bio- and fundamental physics.

  4. 2. Plasmonic Nanospectrocopy of Individual Nanoparticles - Studies of Metal-Hydrogen Interactions and Catalysis

    Author : Svetlana Alekseeva; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; grain boundary; metal-hydrogen interactions; plasmonic sensors; single particle spectroscopy; palladium nanoparticles and nanocrystals; localized surface plasmon resonance; hole-mask colloidal lithography; nanocatalysts; shrinking-hole colloidal lithography; plasmonic nanospectroscopy; dark field scattering spectroscopy; nanoscale effects;

    Abstract : Localized surface plasmon resonance (LSPR) is the phenomenon of collective oscillation of conduction electrons in metal nanoparticles smaller than the wavelength of light used for the excitation. Plasmonic metal nanoparticles are able to confine light to extremely small volumes around them, i.e. below the diffraction limit. READ MORE

    Abstract : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.
