I'm a Graduate Student in the Mechanical, Industrial and Manufacturing Engineering Department at the University of Toledo. Currently I am working as an RA with Prof.Reza Rizvi at the Polymer, Inorganic and Composite Structure Lab having a current research focus of "Exfoliation of 2-D Materials and their application." I have worked to develop a novel way to synthesis low defect 2D layered materials." Now I am working to synthesis conductive ink for flexible electronics from the exfoliated graphene.
Recently our lab has invented a new method known as “CFE or Continuous Flow Exfoliation” , for exfoliating 2-D layered materials using a high pressure gas flowing through a Converging-Diverging(CD) nozzle. This is a result of a series of experiments by Dr.Reza Rizvi(my MS adviser) at the UCLA involving gas exfoliation of 2-D materials. It was realized that the critical component in the exfoliation process is not the gas intercalation effect, but rather a gas relief valve in our set up acting as an annular CD nozzle during the venting stage. Subsequent experiments confirmed that a continuous multiphase isentropic flow of gas and 2-D layered materials through a CD nozzle carefully collected in a solvent will result in a significant fraction (4-10%) of the original material exfoliating in a single layer particles. Now our approach is to:
-
Study the why the materials are being exfoliatedSca (our guess is it’s because of the shock that forms at the diverging section of the nozzle).
-
Scaling the process
-
Application development.
