  2. 21. Development of Capillary Electrophoresis Methods Coupled to Mass Spectrometry for Biomedical and Pharmaceutical Analysis

    Author : Anisa Elhamili; Jonas Bergquist; Magnus Wetterhall; Douglas Westerlund; Alejandro Cifuentes; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Capillary Electrophoresis; Capillary Surface Modificaions; Electrospray Ionization; Mass Spectrometry; Peptides; Intact Proteins; Basic Pharmaceutical Drug Molecules and Complex Biological Samples; Chemistry; Kemi; Analytical Chemistry; Analytisk kemi;

    Abstract : The analysis of large intact proteins and complex biological samples containing drug molecules is a common complicated task for many scientists. However, due to the importance of these molecules, there is a growing interest in pharmaceutical and medicinal research to develop rapid, highly sensitive and efficient analytical techniques.

  4. 22. Exploring the SPR methodology for monitoring of critical attributes in toxicity testing and bioproduction

    Author : Gunnar Bergström; Carl-Fredrik Mandenius; Bengt Danielsson; Linköpings universitet; []
    Keywords : ;

    Abstract : Analysis of biological components is central in bioprocess monitoring, process control, product quality control and cell based toxicity assaying. One of these themes that is pursued in this thesis is the use of biosensors for monitoring of molecular markers, exploiting the natural selectivity of biomolecules. READ MORE

  5. 23. Free Volume Depth Profiling at Polymer Surfaces and Interfaces

    Author : John Algers; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biopolymers; Polymerteknik; Polymer technology; polymer interfaces; polymer surfaces; positron lifetime; free volume;

    Abstract : Pulsed low energy positron beams provide a unique and non-destructive tool to depth probe the free volume of polymers at surfaces and interfaces. Since the employment of low energy positron beams in polymer research is an emerging technique, some focus in this thesis has been on extracting methods and equations needed to interpret the experimental data.

  6. 24. Application of imaging TOF-SIMS in cell and tissue research

    Author : Katrin Richter; Göteborgs universitet; []
    Keywords : TOF-SIMS; imaging mass spectrometry; cryopreparation; ions; lipids; galactosylceramide; sulfatide; fatty acids;

    Abstract : This thesis is aimed at extending the use of TOF-SIMS (time of flight secondary ion mass spectrometry) as an analytical tool in cell and tissue research. TOF-SIMS is a relatively new method that allows analysis of the chemical composition of sample surfaces. READ MORE

  7. 25. Wave propagation in rock and the influence of discontinuities

    Author : Andreas Eitzenberger; Charlie Chunlin Li; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : This thesis concerns wave propagation in rock as a tool for determination of rockproperties and as a consequence of activities, such as trains.Using waves as a tool often means that rock properties are determined or the interior of a sample is studied without being damaged. READ MORE
