06-905: “A rough overview of soft matter”
During the Fall 2005 semester, Mohammad Islam will offer the following special topics course:
06-905: A Rough Overview of Soft Matter
Units: 9.0 Fall
T/Th 1:30 - 2:50 PM
Location: HBH 1510
Description. This course is an introduction to soft condensed matter, or “complex fluids”, including colloids, liquid crystals, surfactants, polymers, and biological structures. The emphasis will be on the unifying physical principles that govern the bulk behavior of these materials. At the end of the course, students should understand the concepts, experimental techniques, and open questions in the field.
Prerequisites. The course will be suitable for graduate students and advanced undergraduates in engineering (all fields), physics, and chemistry. Prerequisites include knowledge of thermodynamics with basic statistical mechanics and some familiarity with Fourier transforms and differential equations.
Topics. I will start with a discussion of the phenomenology, and in particular the structures and rheological behavior, of soft matter. The first few lectures will then focus on intermolecular forces, a brief review of equilibrium statistical mechanics, including linear response theory and fluctuation-dissipation relations, and an introduction to nonequilibrium statistical mechanics. Afterward I will discuss in detail common experimental techniques—scattering, microscopy, rheology, and microrheology—and the fundamental quantities they measure. Colloids are the simplest soft materials to understand, and I will use them to illustrate three key concepts: Brownian motion, self-assembly, and the effect of entropy on dynamics. These concepts will then be applied to liquid crystals, surfactants, polymers, and other systems with more complex interactions. The last part of the course will focus on materials that we don’t yet understand very well: foams, glasses, gels, and living matter such as cells and tissues. I will discuss the most recent experiments that characterize these highly nonequilibrium systems.

06-610 (09-575): Rheology and Structure of Complex Fluids
During the Fall 2005 semester, Lynn Walker will offer the following special topics course:
06-610 (09-575): Rheology and Structure of Complex Fluids
Units: 9.0 Fall
MW 4:30 - 5:50 PM
Location: DH 2105Complex fluids abound in practical applications and are driven by fundamentally appealing dynamics and physics. Macroscopic behavior of these fluids is controlled by the structure inherent to the fluids; so an understanding of the rheology-structure coupling is at the center of this active field of research. This course will cover the basic concepts of rheology and mechanical behavior of fluid systems. Both the experimental and theoretical aspects of rheology will be discussed. The basic forces influencing complex fluid rheology and rheology will be outlined and discussed; including excluded volume, van der Waals, electrostatic and other interactions. Methods of characterizing structure will be covered including scattering techniques, optical polarimetry and microscopy. Examples will focus on several types of complex fluids including polymer solutions and melts, gelling systems, suspensions and self-assembling fluids.

24-739: Special Topics in Thermal-Fluid Sciences: Interfacial Fluid Mechanics
During the Spring 2005 semester, Shelley Anna will offer the following special topics course:
24-739 "Special Topics in Thermal-Fluid Sciences"
Units: 12.0 Spring
MW 8:30 AM - 10:20 AM
Location: Scaife Hall 214This course will cover the basics of interfacial fluid mechanics and multiphase flows, including the formation and flow of multiphase materials like emulsions and foams. We will begin with an overview of static surface and interface properties including surface tension and capillarity as well as equilibrium properties of surfactants both at a surface and in the bulk. We will discuss a range of topics including Marangoni effects and thermocapillary motion, the motion, formation, and dynamics of bubbles, drops and particles in fluid media, free-surface flows like coating flows, and instabilities in two-phase flows including the Rayleigh-Plateau, Saffman-Taylor and Kelvin-Helmholtz instabilities. Advanced topics may include the rheology of multiphase materials, multiphase flows of non-Newtonian fluids, and the influence of interfacial rheology on multiphase flows. We will explore both classical problems on these topics as well as examples from the recent literature.

06-905 Advanced Topics in Colloid and Surface Phenomena
During the Spring 2004 semester, Bob Tilton offered the following special topics course:
06-905 "ADV COLL SURF"
Units: 12.0 Spring
MW 12:30 PM 02:20 PM
Location: DH A310The topic for this spring's course will be Fundamentals and Applications of Surfactants and Macromolecules at Interfaces.
We will talk about the interfacial physical chemistry of surfactants, synthetic polymers and biopolymers including proteins and DNA. Applications will be drawn from materials technology, pharmaceutical processing, and biotechnology.
Students are welcome to take this course for credit or to sign up as an auditor. The latter choice might be suitable for those who have satisfied their course requirements but are interested in learning more about complex fluids or bio-interfacial phenomena.For more information: tilton@andrew.cmu.edu

06-712 "Special Topics in Colloids and Dispersions: The Nature of Light and Its Interaction with Matter"
During the Fall 2003 semester, Dennis Prieve offered the following special topics course:
I plan to use the course to develop material for a new book which is tentatively titled "The Nature of Light and Its Interaction with Matter." The idea is to present the fundamental priniciples behind optical methods of characterization used by many of us in the complex fluids area, such as light absorption, static light scattering, dynamic light scattering, attenuated total internal reflection spectroscopy, plasmon resonance, total internal reflection microscopy, ellipsometry, reflectometry, Brewster-angle microscopy etc.
I will start with the fundamental equations of electrodynamics (Maxwell equations and associated boundary conditions) and present the solution for a linearly polarized plane wave (which can be produced by any laser) reflecting off a planar interface between two dielectrics. This will lead us to some well-known results: the angle of reflection equals the angle of incidence, Snell's law (relation between angle of refraction and the angle of incidence), Fresnel's formulae (relating the intensity of the reflected and refracted wave to the intensity of the incident wave), the existence of a critical angle of incidence (above which total internal reflection occurs), the existence of a Brewster angle …

During the Spring 2001 semester, Simon Biggs offered the following special topics course:
Units: 12.0 Spring
MW 1:30 PM 02:50 PMMy thoughts are revolving around a specialist course of "Polymers at Interfaces". I am thinking of building off of the information in Lynn Walker's course and the colloids course to give some lectures on the role of polymers in colloid science. I am thinking about topics such as (i) conformation at interfaces (effects of concentration, solvency, pH, salt etc. etc.), (ii) bridging and depletion flocculation (origins of forces, controlling parameters, kinetics of flocculation), (iii) steric stabilisation (thermodynamic considerations, solvency effects, intersegmental attractions etc.), (iv) direct measurements of polymers at interfaces (ellipsometry, small angle scattering (SANS, light, x-ray),reflectometry, surface forces (SFA, AFM, TIRM), imaging of adsorbed layers using AFM) and (v) Industrial uses of polymers in colloidal systems.
