Symmetry properties of molecules and solids. Structure of complex and disordered materials. Introduction to thermodynamic functions and laws governing equilibrium properties, relating macroscopic behavior to molecular models of materials. Develops basis for understanding a broad range of materials phenomena, from heat capacities, phase transformations, and multiphase equilibria to chemical reactions and magnetism.

This course focuses on the fundamentals of structure, energetics, and bonding that underpin materials science. It is the introductory lecture class for sophomore students in Materials Science and Engineering, taken with 3.014 and 3.016 to create a unified introduction to the subject. Topics include: an introduction to thermodynamic functions and laws governing equilibrium properties, relating macroscopic behavior to atomistic and molecular models of materials; the role of electronic bonding in determining the energy, structure, and stability of materials; quantum mechanical descriptions of interacting electrons and atoms; materials phenomena, such as heat capacities, phase transformations, and multiphase equilibria to chemical reactions and magnetism; symmetry properties of molecules and solids; structure of complex, disordered, and amorphous materials; tensors and constraints on physical properties imposed by symmetry; and determination of structure through diffraction. Real-world applications include engineered alloys, electronic and magnetic materials, ionic and network solids, polymers, and biomaterials.

Students wear nametags of an ion and find others throughout the school with whom they can create ionic compounds.

This activity will take complex molecules and polyatomic ions the students have learned and construct them out of marshmallows and redhots. This develops understanding in VESPR structures and hybrid molecules.

Phenomenology of mechanical behavior of materials at the macroscopic level. Relationship of mechanical behavior to material structure and mechanisms of deformation and failure. Topics include: elasticity, viscoelasticity, plasticity, creep, fracture, and fatigue. Case studies and examples drawn from a variety of classes of materials including: metals, ceramics, polymers, thin films, composites, and cellular materials.

This course focuses on the latest scientific developments and discoveries in the field of nanomechanics, the study of forces and motion on extremely tiny (10-9 m) areas of synthetic and biological materials and structures. At this level, mechanical properties are intimately related to chemistry, physics, and quantum mechanics. Most lectures will consist of a theoretical component that will then be compared to recent experimental data (case studies) in the literature. The course begins with a series of introductory lectures that describes the normal and lateral forces acting at the atomic scale. The following discussions include experimental techniques in high resolution force spectroscopy, atomistic aspects of adhesion, nanoindentation, molecular details of fracture, chemical force microscopy, elasticity of single macromolecular chains, intermolecular interactions in polymers, dynamic force spectroscopy, biomolecular bond strength measurements, and molecular motors.

Organic chemistry is the study of the carbon and the bonding patterns that make carbon the central element to life. A well-rounded science student must take courses in organic chemistry to understand its application to various other topics, such as the study of DNA, pharmaceuticals, and plastics. In the first semester of organic chemistry, the student will cover the basics. The student will explore different explanations of how molecules bond and learn about the simplest carbon structures (alkanes) before moving on to more complex carbon structures (alkenes and alkynes) and their reactions. The student will then transition into stereoechemistry (the spatial arrangement of atoms) and spectroscopy (methods of identifying molecules) and will conclude the course by examining the four basic organic chemistry mechanisms. This last section will demonstrate electron movement in chemical reactions. Upon successful completion of this course, students will be able to: Describe organic molecules in terms of bonding, stereochemistry, functional groups, and resonance; Demonstrate proficiency in the nomenclature of organic molecules; Derive the intermolecular force of given molecules based on their chemical structures; Draw and represent organic molecules, using arrow notation to show the movement of electrons; Demonstrate proficiency in identifying various classes of reactions (i.e. addition, elimination, arrangements); Describe the thermodynamics of organic reactions using energy diagrams; Analyze the stereochemistry of simple organic molecules and the stereochemical consequences of reactions; Demonstrate proficiency in Newman projections and conformations of cyclohexanes; Demonstrate proficiency in determining whether alkyl halides will undergo a substitution or elimination reaction for a given set of reaction conditions; Describe the basic reaction mechanisms of alcohols; Demonstrate proficiency in calculating the degree of unsaturation of molecules; Describe the basic reaction mechanisms of alkenes and alkynes; Explain the concept of chirality, optical activity, and stereoisomerism; Explain the concept of a carbocation, which is an ion with a positively-charged carbon; Rank different carbocations according to their stability and/or reactivity; Explain the differences between SN1 and SN2 substitution reactions and between E1 and E2 eliminations reactions.
