Laboratory and Campus Tours
NAMRC
33 will provide tours of the following research laboratories as well as
other material processing and manufacturing related facilities located on
campus. You may also want to take a tour of the Columbia University campus
on your own. Maps of the campus will be provided in your registration
packet
Manufacturing Research Laboratory
The
Laboratory hosts various laser systems to facilitate research into novel and
nontraditional manufacturing processes including laser shock peening, laser
peen shaping, laser correction of distortions, laser cleaning, and laser
micro machining. The experimental investigations are complemented by
detailed material characterization and numerical analysis.
The
Columbia Nanomechanics Center
The
Columbia Nanomechanics Research Center is directed jointly by Professor
Jeffrey Kysar of the Mechanical Engineering Department and Professor Xi Chen
of the Civil Engineering and Engineering Mechanics Department. Current
topics of research include nanocomposite thin films which are synthesized by
electrocodeposition of metals and nanoparticles. Mechanical characterization
of the thin films is performed by a thin film bulge tester in the
laboratory. Another current project is to use Electron Backscatter
Diffraction (EBSD) as well as micron scale x-ray diffraction from the
synchrotron source at Brookhaven National Laboratory to characterize the
deformation and stress state induced by plastic deformation of metals.
Facilities in the laboratory include: CNC wire Electrical Discharge Machine
(EDM), laser-interferometric thin film bulge tester to measure stress-strain
response, Bridgman-Stockbarger crystal growth apparatus, microtensile tester
for use in scanning electron microscope, as well as deposition facilities
for nanocomposite thin films.
Optical Nanostructures Laboratory
The
ability to control the flow of light has been greatly aided with the
development of sub-wavelength structures - nanostructures with dimensions on
order tens of nanometers to several hundred nanometers. At these
lengthscales, we can not only perturb the characteristics of light (through
MEMS/NEMS structures), but also directly manage the dispersion of light, its
interaction with atom-like matter, and harness the amazingly extraordinary
behaviors unexpected from the macro lengthscales. We explore these phenomena
experimentally, supported by nanofabrication techniques and theoretical and
numerical simulations.
