  4. 2. Force measurements using scanning probe microscopy : Applications to advanced powder processing

    Author : Anders Meurk; KTH; []
    Keywords : atomic force microscope; AFM; SPM; van der Waals interaction; DLVO-theory; surface forces; colloidal probe; force curve; friction; adhesion; stick-slip; cantilever; calibration; spring constant; silicon nitride; iron; silica;

    Abstract : The object of this thesis is to apply scanning probemicroscopy (SPM) to the field of advanced powder processing.Measurement of interparticle surface forces at conditionsrelevant to ceramic processing has been performed together withthorough studies of powder friction. READ MORE

  5. 3. Modeling of non-equilibrium scanning probe microscopy

    Author : Alexander Gustafsson; Magnus Paulsson; Tchavdar Todorov; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; scanning tunneling microscopy; molecular dynamics; density functional theory; non-equilibrium Green s functions; Condensed Matter Physics; Kondenserade materians fysik;

    Abstract : The work in this thesis is basically divided into two related but separate investigations.The first part treats simple chemical reactions of adsorbate molecules on metallic surfaces, induced by means of a scanning tunneling probe (STM). The investigation serves as a parameter free extension to existing theories. READ MORE

  6. 4. Scanning Probe Microscopy: Design and Applications

    Author : Håkan Olin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : A compact scanning tunneling microscope (STM) and a scanning ion-conductance microscope (SICM) has been constructed. The concentric microscope head was built around a commercial piezoelectric inchworm motor that was used for coarse positioning. The microscope has a high resonance frequency (9.6 kHz), low noise (0.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biological Physics; Biologisk fysik;

    Abstract : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. READ MORE
