  1. 1. Concentration measurements in single particle microscopy

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Magnus Röding; Göteborgs universitet.; Gothenburg University.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion; fluorescence microscopy; nanoparticle characterization; number concentration; optical wide-field microscopy; single particle tracking; Smoluchowski process;

    Abstract : The topic of this thesis is the introduction of two novel methods for using single particle microscopy as a tool for absolute number concentration measurements of Brownian particles. The key idea of both methods is that in order to estimate number concentration, the size of the (three-dimensional) particle detection region has to be estimated. READ MORE

    Abstract : The recent development of microscopy methods, biological assays and bioanalytical sensors has significantly advanced the understanding of biological systems. Surface-based bioanalytical sensors have in recent years gained increased interest thanks to improvements in sensitivity and simplicity to use. READ MORE

  3. 3. Light scattering for analysis of thermal stress induced deformation in thin metal films

    University dissertation from Stockholm : Fysik

    Author : Carina Kylner; KTH.; [1997]
    Keywords : thin metal films; aluminum; optical quality; hillock; initial stage; lateral distribution; thermal stress; light scattering; instrument.;

    Abstract : Today, thin film based devices are found in a wide field of applications. The main reasons are that thin film technology enables access to unique physical properties and possibilities to miniaturize devices. Thin film devices are generally described in terms such as electrical, optical and magnetical properties. READ MORE

  4. 4. Super-resolution Luminescence Micro-Spectroscopy : A nano-scale view of solar cell material photophysics

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Chemical Physics

    Author : Aboma Merdasa; Lund University.; Lunds universitet.; [2017-01]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; super-resolution microscopy; Single Molecule Spectroscopy; J-aggregates; perovskites; photophysics;

    Abstract : Optical microscopy is a fundamental tool in a range of disciplines encompassed by the physical and biological sciences. At the dawn of this millennium, a break-through was made in optical microscopy where super-resolution methods emerged and declared imaging beyond the optical diffraction limit a possibility. READ MORE
