The Electron Microscope Lab is a College Shared Lab, and consists of two major equipment, namely Transmission Electron Microscope (TEM) and Environmental Scanning Electron Microscope (ESEM). The Lab is located on the first floor of the John A. Peoples Building (JAP), Room 105. The lab provides services to faculty, students and research scholars.

Overview of TEM
Transmission Electron Microscope (TEM) was obtained by Dr. Paul B. Tchounwou through his NIH grant. The TEM model is JEOL-1011 with a resolution of 0.2 nm lattice with magnification of 50 to 1,000,000 under the accelerating voltage of 40 to 100 kV. The JEM-1011 is a compact high performance TEM with advanced features and functions. Its high contrast objective lens polepiece combines the highest possible contrast and brightness with optimum resolution.
Overview of ESEM
Environmental Scanning Electron Microscope (ESEM) was obtained by Dr. Farshad Amini through his NSF MRI grant. The SEM model is Quanta 200, which provides the necessary environment to allow any sample data collection in a true “all in one” SEM high-vacuum, SEM low-vacuum, and ESEM system. The system allows moist/wet samples, hot or dirty specimens be examined in their natural states without any special preparation (such as drying or coating) that can mask or damage the structure to be viewed.
