Lecture plan, UMASS 2013 summer school

Lecture 1 --Basics

  • Pictures of irreversible phenomena
  • Outline of course.
  • Orders of magnitude of a colloidal dispersion; length, time, energy.
  • Interaction with fluid

    Lecture 2 --Fractals and opacity

  • Irreversible aggregation.
  • Mathematical fractals; measures of fractality
  • scattering.
  • Opacity as a measure of interaction
  • viscosity, elasticity

    Lecture 3 --Controlling objects by external forcing

  • Sedimentation: onsager matrix, scaling with size, stokeslet representation
  • how shape influences chiral response
  • Electrophoresis, different induced flow, different scaling with size.
  • Rotational response: twist matrix
  • Types of aligning behavior. symmetric, non-axially aligning, axially aligning.
  • Response to time-dependent force: achieving full alignment.

    Lecture 4 --Colloidal phase separation

  • Finish topics from lecture 3
  • conventional phase separation
  • Elastic phase separation
