  1. 1. Design of robust preparative chromatography

    Författare :Marcus Degerman; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; optimization; modeling; preparative chromatography; Design space; Control Space; uncertainty analysis;

    Sammanfattning : This work presents a methodology for analyzing and optimizing preparative chromatographic processes. It uses a model-based approach to find the critical process parameters, analyze the control space and suggest a design space that can be registered with the regulatory agencies. LÄS MER

  3. 2. BUILDING AN X-RAY PHOTOELECTRON SPECTROSCOPY ENDSTATION FOR OPERANDO STUDIES OF CATALYTIC CO AND CO2 HYDROGENATION REACTIONS

    Författare :David Degerman; Anders Nilsson; Joachim Schnadt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kemisk fysik; Chemical Physics;

    Sammanfattning : X-ray Photoelectron Spectroscopy (XPS) provides an element-specific surface sensitive probe of the chemical composition in a system, and is consequently one of the workhorses of surface science and catalysis research. The obtained information on the chemical and physical state of the catalyst and adsorbates is essential in the endeavor to achieve a fundamental understanding how chemical reactions are facilitated by the catalyst.

  4. 3. CO, CO2 and N2 hydrogenation reactions probed by operando x-ray photoelectron spectroscopy

    Författare :David Degerman; Anders Nilsson; Miquel Salmeron; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Operando Catalysis; Hydrogenation reactions; High-Pressure X-Ray Photoelectron Spectroscopy; Syngas; kemisk fysik; Chemical Physics;

    Sammanfattning : Catalytic reactions are essential for generating the chemical products required by the modern society. In particular, reactions related to clean energy storage and generation as well as fertilizer production are facilitated by catalysts. However, the processes are often insufficiently understood at a mechanistic level. LÄS MER

  5. 4. Time-Lapse Bright-Field Microscopy and Image Acquisition of In-Vitro Neural Stem Cells

    Författare :Johan Degerman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This project involves development of a system for time-lapse image acquisition of neural stem cells. The purpose of analyzing time sequences is to find migrational patterns that are characteristic for different cell types. LÄS MER

  7. 5. Time-Lapse Microscopy Imaging and Image Analysis for Cell Migration Studies

    Författare :Johan Degerman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cell image segmentation; computational imaging; cell migration modelling; Time-lapse microscopy;

    Sammanfattning : This thesis considers a complete automatic system for in-vitro cell imaging and migration image analysis. The development of such can be divided into three main problems:The first considered problem concerns how to build a robust time-lapse sequence acquisition system, for imaging adult hippocampal cells in bright-field microscopy.
