CHEMENG 260: Polymer Science and Engineering (CHEMENG 160)

Interrelationships among molecular structure, morphology, and mechanical behavior of polymers. Topics include amorphous and semicrystalline polymers, glass transitions, rubber elasticity, linear viscoelasticity, and rheology. Applications of polymers in biomedical devices and microelectronics. Prerequisites: CHEME 31 A,B or CHEM 31X, CHEM 33 and 171, or equivalent.

CHEMENG 420: Growth and Form

Advanced topics course examining the role of physical forces in shaping living cells, tissues, and organs, making use of D'Arcy Thompson's classic text On Growth and Form. The course begins with a review of relevant physical principles drawn from statistical physics, polymer theory, rheology and materials science. We then examine current knowledge of cellular mechanotransduction pathways, the roles of physical forces in guiding embryonic development, and the contribution of aberrant cellular response to mechanical cues in heart disease and cancer. The course concludes by examining current frontiers in stem cell biology and tissue engineering.

CHEMENG 442: Structure and Reactivity of Solid Surfaces

The structure of solid surfaces including experimental methods for determining the structure of single crystal surfaces. The adsorption of molecules on these surfaces including the thermodynamics of adsorption processes, surface diffusion, and surface reactions. Molecular structure of adsorbates. Current topics in surface structure and reactivity, including systems for heterogeneous catalysis and electronic materials.

CHEMENG 462: Complex Fluids and Non-Newtonian Flows (ME 455)

Definition of a complex liquid and microrheology. Division of complex fluids into suspensions, solutions, and melts. Suspensions as colloidal and non-colloidal. Extra stress and relation to the stresslet. Suspension rheology including Brownian and non-Brownian fibers. Microhydrodynamics and the Fokker-Planck equation. Linear viscoelasticity and the weak flow limit. Polymer solutions including single mode (dumbbell) and multimode models. Nonlinear viscoelasticity. Intermolecular effects in nondilute solutions and melts and the concept of reptation. Prerequisites: low Reynolds number hydrodynamics or consent of instructor.

CHEMENG 469: Solid Structure and Properties of Polymers

Fundamental structure-properties relationships of solid polymers in bulk and thin films. Topics include chain conformations in bulk amorphous polymers, glass transition, crystallization, semi-crystalline morphology, liquid crystalline order, polymer blends, block copolymers, polymer networks/gels, semiconducting polymers, and experimental methods of characterizing polymer structure.

CHEMENG 470: Complex Fluid Interfaces: Capillarity and Interfacial Dynamics

Complex fluid interfaces arise whenever amphiphiles (surfactants, phospholipids, polymers, colloidal particles) collect at liquid-fluid surfaces, imbuing them with nonlinear mechanical responses. Examples in nature include the cell membrane, lung surfactants, and the tear film. Industrial applications include emulsions and foams that require stabilization. The course discusses concepts in capillarity and wetting, interfacial fluid dynamics, thin film stability, the microstructure of self-organized monolayers and bilayers. Experimental microstructural methods (Brewster angle microscopy, fluorescence microscopy, grazing incidence x-ray diffraction) will be described. Prerequisite: 310 or equivalent.
