  2. 1. Particle Coating in a Wurster Type Bed

    Author : Stina Karlsson; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drying; Particle; Tracking technique; Spouted bed; Fluidisation; Multiphase flow; CFD; Trajectory; Coating; Wurster;

    Abstract : The Wurster bed process is frequently used for film coating. In the Wurster bed, particles circulate in the equipment and are sprayed with a liquid which forms a coating when dry. The procedure is repeated until the desired characteristics of the coating layer are obtained. READ MORE

  4. 2. Electrifying the Molecules of Life : Peptide and Protein Analysis by Capillary Electrophoresis Coupled to Electrospray Ionization Mass Spectrometry

    Author : Magnus Wetterhall; Jonas Bergquist; Karin E. Markides; Dominic M. Desiderio; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Capillary electrophoresis CE ; Electrospray ionization ESI ; Mass spectrometry MS ; Peptides; Proteins; Cerebrospinal fluid CSF ; Graphite coating; Monomer coating; Polymer coating; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : This thesis describes the current status and novel aspects of the analysis of the molecules of life, i.e. peptides and proteins, using capillary electrophoresis (CE) coupled to mass spectrometry (MS) via (sheathless) electrospray ionization (ESI). Early reports of sheathless CE-ESI-MS were plagued by limited lifetimes of the electrospray emitter. READ MORE

  5. 3. The Prediction of Fluid Flow, Particle In-Flight and Coating Characteristics in Atmospheric Plasma Spraying

    Author : Per Nylén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle temperature; coating temperature; coating thickness; particle velocity; plasma spraying; fluid flow; modelling;

    Abstract : The aim of this thesis is to make a contribution to the development and application of models for the simulation and optimisation of plasma spray processes in production engineering. In particular, focus is placed on the development, combination and application of models for coating deposition and robot motion optimisation, the prediction of coating temperatures during deposit, the simulation of the plasma flow field, and in-flight characteristics of injected particles.

  6. 4. Particle motion, coating and drying in Wurster fluidized beds - An experimental and discrete element modeling study

    Author : Liang Li; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airflow; Wurster; coating; CFD; particle; Fluidized bed; drying; PEPT; spray; DEM;

    Abstract : This thesis focuses on developing a mathematical model that is capable of predicting the fluidized bed coating process. First a basic understanding of pellet motion in a Wurster fluidized bed was established by conducting a series of experiments using the positron emission particle tracking (PEPT) technique.
