  2. 1. In situ Sequencing Methods for spatially-resolved transcriptome analysis

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Marco Mignardi; Stockholms universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Padlock probes; rolling circle amplification; in situ sequencing; spatially-resolved transcriptomics; molecular diagnostics; biokemi; Biochemistry;

    Abstract : It is well known that cells in tissues display a large heterogeneity in gene expression due to differences in cell lineage origin and variation in the local environment at different sites in the tissue, a heterogeneity that is difficult to study by analyzing bulk RNA extracts from tissue. Recently, genome-wide transcriptome analysis technologies have enabled the analysis of this variation with single-cell resolution. READ MORE

    Abstract : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.

  5. 3. Domain engineering in KTiOPO4

    University dissertation from Stockholm : KTH

    Author : Carlota Canalias; KTH.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quasi-phase matching; KTiOPO4; ferroelectric domains; atomic force microscopy; periodic electric field poling; polarization switching; second harmonic generation; TECHNOLOGY Engineering physics Optical physics; TEKNIKVETENSKAP Teknisk fysik Optisk fysik;

    Abstract : Ferroelectric crystals are commonly used in nonlinear optics for frequency conversion of laser radiation. The quasi-phase matching (QPM) approach uses a periodically modulated nonlinearity that can be achieved by periodically inverting domains in ferroelectric crystals and allows versatile and efficient frequency conversion in the whole transparency region of the material.

  6. 4. Generation of induced neurons via direct conversion in vivo and in vitro

    University dissertation from Neurobiology

    Author : Olof Torper; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cellular reprogramming; cell replacement therapies; induced dopaminergic neurons; in vivo reprogramming; Lentiviral vectors; AAV vectors;

    Abstract : Cellular reprogramming is when one cell is changed into another. This involves structural modifications on the DNA of a cell resulting in a transcriptional change. This occurs naturally during development when early pluripotent cells gradually differentiate into more specialized cells that finally result in a complete organism. READ MORE

  7. 5. In-situ Investigations of Lithium-Sulfur Batteries

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Matthew Sadd; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : As the demand for high energy-density storage devices increases, we must look beyond the current state of the art technology, the lithium-ion battery. Lithium-ion battery technologies are approaching their theoretical limit in terms of capacity, and now that the demand for longer-range electric vehicles (EVs) and the implementation of grid storage is increasing, we need to provide technologies that can go beyond what is currently possible.
