  1. 1. Confined Compression of Single Particles Development of a Novel Triaxial Testing Instrument and Particle-Scale Modelling

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Henrik Jonsson; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Powder compaction; Compression; Single particle; Particle mechanics; Powder mechanics; Confined conditions; Triaxial; Apparatus design; Modelling; Galenisk farmaci; Pharmaceutics;

    Abstract : When predicting the performance of a powder compaction process, assessing the behaviour of the particles comprising the powder bed is of central relevance. Currently, however, no experimental methods are available for mimicking the multiaxial loading conditions imposed on the individual particles in a powder bed during compaction, and such analyses are therefore usually performed in silico.

  2. 2. Single Molecule Detection Microfluidic Automation and Digital Quantification

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Malte Kühnemund; Uppsala universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; single molecule; digital; rolling circle amplification; magnetic particle; padlock probe; microfluidics; resistive pulse sensing; lab on chip; mobile phone microscopy; enrichment; sequencing;

    Abstract : Much of recent progress in medical research and diagnostics has been enabled through the advances in molecular analysis technologies, which now permit the detection and analysis of single molecules with high sensitivity and specificity. Assay sensitivity is fundamentally limited by the efficiency of the detection method used for read-out. READ MORE

  4. 4. 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

  5. 5. Single Copper Nanoparticle Oxidation

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Sara Nilsson; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dark-field scattering spectroscopy; single particle; plasmonic nanospectroscopy; plasmonic sensing; transmission electron microscopy; oxidation; nanoscale Kirkendall effect;

    Abstract : Cu nanoparticles are commonly used in microelectronic devices and as catalysts in, for example, methanol synthesis and methanol steam reforming reactions. However, Cu nanoparticles are prone to oxidation. READ MORE
