(Taught in collaboration with Professor Mark Ratner) This survey course provides an overview of energy issues in the context of climate change and global sustainability. Energy demand for industrial, transportation, housing and commercial uses are presented, and strategies for demand reduction are discussed. Energy supply is presented from the point of view of mature echnologies (fossil and nuclear fuels, hydro power) and upcoming, renewable sources (solar, wind, geothermal, wave and tidal, biofuels). Finally, issues associated with energy storage (batteries) and transport (smart net) are discussed with particular emphasis on the hydrogen economy. While this course will address many technological and scientific aspects of energy, no prerequisite technical courses are required from the students. Guest lecturers will present other non-technical facets of the energy topic, including social, legal and economic issues.

This introductory class to materials science and engineering provides a first survey of the field by emphasizing the structure/property/processing relationship. General concept are first introduced in the area of atomic bonding, crystallography, crystalline imperfections, diffusion, phase transformations and phase diagrams. Mechanical properties are then discussed, with particular emphasis on plasticity, strengthening, fracture, fatigue and creep. These concepts are then applied to individual materials classes: metals, ceramics and polymers, with discussion of processing of these materials. Electrical and magnetic properties, as well as corrosion damage are finally presented.
Mat Sci 332
This course reviews plastic deformation and fracture of materials, emphasizing structure/property relations. The role of imperfections, state of stress, temperatures, strain-rate, environment on mechanical behavior of metals, polymers and ceramics are examined. Students will investigate, in a quarter-long laboratory team project, a series of material's mechanical properties using the Central Laboratory for Materials Mechanical Properties (CLaMMP). In 2007, student team compared pairs of pristine/recycled materials such as paper, concrete, polyethylene, aluminum and countertop materials.

This course is a materials science approach to the challenge of creating energy-efficient devices and systems. It introduces first the concept of materials energy content (production, processing, use and recycling), with students developing case studies in this area. It then describes how advanced materials make possible efficient energy capture (solar cells, nuclear materials, hard materials for oil/gas recovery, composites for wind energy, …), energy conversion (fuel cells, light emitting diodes, thermoelectrics, engines and turbines, …) and energy storage (hydrogen storage, phase-change materials,…). Also, materials enabling energy-efficient transportation and housing will be discussed.
Mat Sci 406
This class, part of the compulsory core of six MSE graduate classes, addresses the elastic response, plastic deformation and fracture of materials, emphasizing structure/property relations. Role of imperfections, state of stress, temperature, strain-rate, environment on mechanical behavior of metals, polymers, ceramics and composites are examined, with emphasis on fundamental mechanisms associated with the microstructure of materials.
The class provides also a quarter-long computational laboratory, taught by Dr. Emery, on finite-element modeling of mechanical behavior of materials, where students tackle a series of increasingly more complex mechanical situations.

Mat Sci 435
This course covers the mechanics and microstructure of structural materials for high-temperature applications. The mechanisms of time-dependent deformation and failure at high homologous temperature are treated in a quantitative manner. Materials used at high temperature (metals, ceramics and their composites) are reviewed, with emphasis on the relationship between microstructure and high-temperature mechanical properties.
