Microscopy

AFM

The Department of Chemical and Biomolecular Engineering maintains two identical state-of-the art Atomic Force Microscopes (AFMs).  The PicoSPM AFM unit is equipped for contact mode, tapping mode (both Acoustic and Magnetic AC modes) and pulsed force mode imaging.  Samples can be imaged in air, under a controlled atmosphere (using an environmental chamber), in liquid and also at a controlled temperature(-30 to 170C). There are also two top-down scanners which allow scanning a maximum area of 6 x 6 microns and 30 x 30 microns. 

SEM/TEM

Electron microscopy is available through the Coordinated Instrumentation Facility (CIF).  The JEOL 2010 Scanning Transmission Electron Microscope (STEM) has the following features:

bullet200 kV maximum accelerating voltage.
bulletLab 6 filament.
bulletPossible 0.5 nm resolution in scan mode.
bulletEnergy-Dispersive X-ray System (EDS) for elemental mapping.

The JEOL JSM-820 has:

bulletHigh resolution digital imaging
bullet6" diameter specimens
bulletBackscatter detector
