The Banaszak Holl Group Laboratories
We perform our research in labs in the Chemistry Department, the Physics Department, and the Biological Sciences Research Building at the University of Michigan. The combination of these laboratories provide us excellent space and facilities for synthesis and characterization, surface analysis, and a full suite of cell biology labs including tissue culture, fluoresence microscopes, and flow cytometry.
The Michigan laboratories are fully equipped for the synthesis of inorganic, organometallic, main complexes, and polymer synthesis. Pictures of our inert atmosphere box and Schlenk lines are shown below.
A large part of our research focuses on surfaces and solid/solid interfaces. We are also equipped with a surface chemistry laboratory to pursue these studies. The techniques available in our labs in the Michigan chemistry department include X-ray Photoelectron Spectroscopy, Surface Infrared Spectroscopy, Low-Energy Electron Diffraction, and Mass Spectroscopy. The pictures below highlight the XPS and IR spectrometers.
All the surface science techniques are combined in one system so that they can be used in concert to study a particular sample. The sample preparation chambers, and load lock that allows us to get sample in and out of the UHV environment in about 30 minutes, are shown below.
Scanning Probe Microscopy Studies
Scanning Tunneling Microscopy (STM) has become a technique of major importance for surface chemistry. Our STM studies are performed on a beautiful RHK microscope located in Prof. Brad Orr's laboratory in the Physics department. The picture below shows the imaging head the holds the STM tip in place over a sample. Using this technique, it is possible to achieve atomic resolution images of surface structure.
We jointly purchased a Digital Nanoscope IIIa AFM and a Molecular Imaging AFM with Prof. Orr. These instruments can perform contact and tapping AFM, phase imaging and force modulation studies, and magnetic force imaging.
