Fall 2010-Summer 2012

Tuskegee University, Tuskegee, AL

Tuskegee Center of Advanced Materials, Research Assistant

Worked on research project under my supervisor Dr. Vijay Rangari synthesizing a new facile way of producing graphene nanoparticles using furnace. The process involves Swagelok bolt locking mechanism. Measurements of thermal conductivity were taken on the Mathesis Thermo conductivity Analyzer on graphene with the addition of epoxy at various temperatures using a Tenney F4Watlow furnace to control heating and cooling conditions. I also had training using various instruments for the characterization of nanoparticles. Instrumentation that I have used includes the x-ray difractometer for the purity and the structure of the sample. The differential scan calorimetry was use to measure the Tg, and the crystalinity of the sample and the change of integrity of the sample against the reference sample as heat is being applied. Other instruments include the scan electron microscopy, transmission electron microscopy, and the chemical vapor deposition. I have had training on the first nanotechnology chemical vapor deposition which includes operation and maintenance. Research grant includes (RISE) research infrastructure in science and engineering, (PREM) Primary research of engineering materials and STC science technology center provided the funding for energy efficiency for electronics. My research involved the use of dichalcogenides to lower the energy output to power electronic devices by using monolayered transition metals containing sulfur.
