  1. 1. Surface interactions and adsorbate structures : An atomic force microscopy study

    Author : Goran Bogdanovic; KTH; []
    Keywords : atomic force microscope; AFM; cantilever calibration; colloidal probe; surface force; force curve; friciton; hydrophobic; adhesion; roughness; multilayer; silica; cellulose; cationic polyelectrolyte; MAPTAC;

    Abstract : Atomic force microscopy, AFM, was used for studying somecurrent topics in the field of surface and colloid science. Themain topics addressed in this thesis were: the nature of thelong-range attraction between hydrophobic surfaces; slidingfriction behavior for microscopic contacts; and interfacialstructuring of polyelectrolyte-nanoparticle multilayerfilms.

  2. 2. Leibniz on Agency and Force

    Author : Peter Myrdal; Lilli Alanen; Pauliina Remes; John Carriero; Michael Della Rocca; Uppsala universitet; []
    Keywords : HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Leibniz; Gottfried Wilhelm; 1646-1716; Early Modern Philosophy; Agency; Force; Final causes; Theoretical Philosophy; Teoretisk filosofi;

    Abstract : This is a study of Leibniz’s theory of agency – his theory of the nature of causal powers and agents. Leibniz develops his view against the background of an Aristotelian conception of agency. The latter was rejected by many early modern philosophers in the wake of the mechanist conception of the natural world. READ MORE

  3. 3. Reconstructing force from harmonic motion

    Author : Daniel Platz; David B. Haviland; John E. Sader; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; oscillator; force spectroscopy; atomic force microscopy; intermodulation; multifrequency; inverse problem; high quality factor;

    Abstract : High-quality factor oscillators are often used in measurements of verysmall force since they exhibit an enhanced sensitivity in the narrow frequencyband around resonance. Forces containing frequencies outside this frequencyband are often not detectable and the total force acting on the oscillatorremains unknown. READ MORE

  4. 4. 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. 5. Imaging materials with intermodulation : Studies in multifrequency atomic force microscopy

    Author : Daniel Forchheimer; David Haviland; Arvind Raman; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; atomic force microscopy; nonlinear dynamics; frequency mixing; force reconstruction; Physics; Fysik;

    Abstract : The Atomic Force Microscope (AFM) is a tool for imaging surfaces at the microand nano meter scale. The microscope senses the force acting between a surfaceand a tip positioned at the end of a micro-cantilever, forming an image of the surface topography. READ MORE
