  2. 1. 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

  4. 2. Adhesion and Friction - a Study on Tactility

    Author : Kenneth Duvefelt; Ulf Olofsson; Emile Van Der Heide; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

    Abstract : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. READ MORE

  5. 3. New methods for evaluation of tissue creping and the importance of coating, paper and adhesion

    Author : Jonna Boudreau; Christophe Barbier; Ulf Germgård; Sverker Albertsson; Robert Pelton; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue; creping; paper adhesion; Tissue paper; creping; paper adhesion; coating layer; adhesives; Yankee cylinder; crepe structure; wavelength measurements; Chemical Engineering; Kemiteknik;

    Abstract : The creping process and the conditions on the Yankee cylinder dryer are key factors in a tissue paper mill, and they therefore need to be kept under good control in order to maintain a high and uniform quality. To this end it would be valuable to be able to make on-line measurements of Yankee coating thickness as well as the crepe structure of the tissue paper. READ MORE

  6. 4. Platelet Adhesion to Proteins in Microplates : Applications in Experimental and Clinical Research

    Author : Andreas Eriksson; Per Whiss; Håkan Wallén; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; platelets; platelet adhesion; platelet assay; synergistic activation; thrombosis; anti-platelet treatment; Pharmacology; Farmakologi;

    Abstract : Platelets are crucial for prevention of blood loss after vessel injury. Platelet adhesion to disrupted vessel walls is mediated by receptors such as the GPIb-IX-V complex that binds von Willebrand factor and the collagen-binding integrin α2β1. READ MORE
