  1. 16. Nanoscale studies of functional materials using scanning probe microscopy

    Författare :Jesper Wittborn; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis deals with developing suitable modifications ofScanning Probe Microscopy (SPM) for investigations offunctional properties of materials. In order to make itpossible to investigate a number of properties of variousfunctional systemsusing SPM the following new techniques have beendeveloped:    A magnetic force microscope (MFM) having capability ofboth dc- and ac-mode detection.

  4. 18. Structural Studies Of Materials Using Time-Resolved X-ray Diffraction

    Författare :Hengameh Allaf Navirian; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structure of bulk crystal; x-ray diffraction; phase transition; mechanical properties; microscopy;

    Sammanfattning : This work consisted of the application of X-ray diffraction methods to the study of ultrafast phenomena in various materials. Since the X-ray pulses generated from the bending magnet at the MAX II ring, where most of the experimental work was conducted, have a duration of the order of 300 ps, they can not be used directly as probe pulses in experiments where higher temporal resolution is required.

  5. 19. Molecular mechanisms of biphasic insulin secretion

    Författare :Nikhil R. Gandasi; Sebastian Barg; Christien Merrifield; Uppsala universitet; []
    Nyckelord :Exocytosis; Insulin secretion; Membrane trafficking; Microscopy; Diabetes; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Pancreatic beta-cells secrete insulin in response to increase in blood glucose concentration with a rapid first phase and slower, sustained second phase. This secretion pattern is similar in entire pancreas, isolated islets of Langerhans and single beta-cells and it is disrupted in type 2-diabetes. LÄS MER

  7. 20. Genotyping and Mutation Detection In Situ : Development and application of single-molecule techniques

    Författare :Ida Grundberg; Mats Nilsson; Ulf Landegren; Olli-Pekka Kallioniemi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; padlock probes; in situ; rolling circle amplification; mRNA; genotyping; mutation detection; cancer; tissue sections; diagnostics; single-molecule; single-cell; microscopy; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Molekylär medicin; Molecular Medicine;

    Sammanfattning : The human body is composed of trillions of cells closely working together to maintain a functional organism. Every cell is unique in molecular composition and can acquire genetic variations that might cause it to turn pathological. LÄS MER
