Description:

The Keck-II Center was established in late 2001 through the support of W. M. Keck Foundation. Keck-II also has received some support from Northwestern's Institute for Nanotechnology's NSF-sponsored Nanoscale Science & Engineering Center (NSEC) as well as from the State of IL and Northwestern. Keck-II facilitates research, collaboration, education and outreach in all science from soft biological matter to hard physical matter, specializing in surface analysis and nano-scale characterization.  Keck-II hosts Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS), X-ray Photoelectron Spectroscopy (XPS), Fourier Transform Infrared Spectroscopy (FT-IR), Confocal Raman System, High Resolution Stylus Profilometer, 3D Optical Microscope, Spectroscopic Ellipsometer, and Zetasizer. Keck-II is open to all the faculty and students at Northwestern University as well as the researchers at the nearby academic institutions and related industrial companies. The Keck-II Center operates and functions like its sister facilities (SPID and EPIC)-based on the core philosophy of open-access, hand-on training, collaboration and assistance from our able staff. Training is offered on a periodic basis, both as “crash courses” or part of hands-on structured courses, as well as individual ad-hoc training as need arises.
