TEACHINGAE 523: Nanoscale Contact Mechanics: This course focuses on aspects of SPMs to provide fundamental/theoretical background in connection with practical operations. Topics include adhesive contact mechanics, short & long-range force interactions, principles of Scanning Tunneling Microscopy (STM), electron tunneling, tip & surface preparation, AC and DC Atomic Force Microscopy (AFM), detectors, control systems, basics of piezoelectric elements, issues and solutions in SPM instrumentation, force/scale calibration, modeling of oscillating cantilever, force interactions with surface, stability conditions, optimization of AC/DC experiments, high-resolution AFM, force spectroscopy, energy dissipation at the AFM tip, lateral contact stiffness, scanning thermal microscopy, electrostatic force and Kelvin probe microscopy, capacitance sensing, quantitative magnetic force studies, near-field optical imaging, molecular spectroscopy, macromolecular deposition/unfolding/binding, atomic friction, quantitative mechanics at the nanometer scale, application of SPMs in biological systems. The course includes four laboratory assignments where basic and advance principles in AFM are taught, the appication of theory in instrumented nanoindentation is studied, and the measurement of adhesive energies at the nanoscale using SPM probes is conducted. AE 461: Structures and Controls Laboratory: This course examines theory and application of experimental techniques in aerospace engineering with emphasis on structural mechanics, vibrations, dynamics, and control systems. The course includes 2-hour lectures and 9 laboratory assignments with regular pre-lab and post-lab reports and memos. AE 321: Aerospace Structures I: This course examines fundamental concepts in the linear theory of elasticity, including stress, strain, equilibrium, compatibility, material constitution and properties. Introduction to failure mechanisms and criteria. Application to plane stress/strain problems, beams in extension and bending, and shafts in torsion. AE 322/323: Aerospace Structures II: This course examines fundamental concepts in the analysis of beams and shafts of monocoque and semi-monocoque construction, energy methods, theory of elastic stability with applications to buckling of columns, introduction to finite element structural analysis - with application to trusses, frames, and plane stress/strain problems. |
