  • Course Description

    This advanced course in “Particle Characterization” deals with methods and techniques for quantitatively and qualitatively evaluating properties of single particles and particulate assemblies. Emphasis is on the fine-particle size range, from micrometers to nanometers. Particle characteristics are linked to relevant applications in industry. Transport properties, adhesion/ cohesion phenomena and surface-particle removal mechanisms are dealt with in detail. Contents: Introduction: Need for studying particle characteristics; Typical industrial applications; emerging nano-particle technologies; microelectronics applications. Single Particle: Concept & Definition; Particle Surface; Surface-Fluid Interactions; Sub-Surface Region; Internal Grain Boundaries; Interior of Particle; Size; Shape. Particulate Assemblies: Description & Properties; Statistical Concepts; Mean Diameters & Shape Factors; Distribution Functions & Models; Surface Area & Specific Surface Calculations. Fine Particle Characterization: Size Analysis & Sampling; Shape Determination Methods; Pattern Recognition & Feature Extraction; Particle Signature & Meloy Equations; Property Representation. Physico-Chemical Properties: Visual Appearance; Absorption; Electrical Properties; Transport Properties; Adhesion & Deposition; Removal from Surfaces; Magnetism; Thermal Conductivity; Aggregation, Coagulation & Restructuring; Chemical Properties. Applications: Dust Explosions; Dust Flame Propagation; Health Hazards; Deserts & Sand Movement; Hazard Potential of Heat-Transfer Fluids; Atmospheric Aerosols; Nano-technology.
