Conducted a wide variety of quantum-based simulations for both organic and inorganic applications. Through the extensive use of molecular dynamics theory as well as post-processing codes written primarily in C++, Python and MATLAB, I was able to examine phenomena in the following cases:1. The misfolding of alpha de-novo based proteins in different nanopores.The group I was a part of wrote an extensive program in Fortran in order to simulate the folding behavior of proteins in different pore geometries. The comparison indicates that the protein is more stable in the spherical cavity than in the cylindrical pore, followed by the slit pores.2. Tribological behavior of sililcon carbide under high performance conditions.Through the use of molecular dynamics theory, I simulated the frictional behavior of silicon carbide under extreme conditions. The results indicated a decrease in the friction coefficient with increasing velocity due to the formation of excess free volume at the interface. These results were verified experimentally through the use of Atomic Force Microscopy.3. Superlubricity of graphene coupled with a variety of precious metals such as gold, silver and platinum.The results verified current experimental findings and expanded upon them by determining a transition from superlubricity to lubricity when one examines gold, silver and platinum crystals.4. Effect of flash heating on the sliding friction between quartz layers at subseismic slip rates.Flash heating events increase in frequency as a function of increasing sliding velocity, contributing to the increase in the interfacial temperature. For small thickness, we saw high rates of heat transfer. The efficiency of the heat transfer is reduced significantly with increased thickness, resulting in a weakened material. Using stress-strain diagrams indicate clearly a decay in the stress, as well as a transition from brittle to ductile behavior, as the sliding velocity increases.

This project concerned the design, simulation, optimization and analysis of a Deethanizer, Demethanizer and Cold Box Apparatus of an ethylene plant, for which I was the project manager.The design of the Separations II process initiated from the literature survey done through the use of the text “Plant Design and Economics for Chemical Engineers” by Peters and Timmerhaus. Based upon this information, coupled with the client’s desired unit specifications, the design of this section began on February 22, 2010 with the derivation of the preliminary process flow diagram. Separations II design team consists of three design engineers. Furthermore, each section will be divided into 3 portions with each Engineer responsible for a particular component of the Project.My primary role, as Project Manager, was to consistently monitor the progress of the project as well as to keep close coordination between the Separations I Team as well as the Purification Team and the Utilities Team. The former 2 sections represent the inlet and outlet streams of the Separations II Process. The latter section was of importance with respect to the refrigerant required for the Cold Box Apparatus.In addition to these responsibilities, I also completed an individual design portion of this project in the form of the Deethanizer column.

Lead Project Manager in the design and testing of an autonomous fuel cell-powered model car for entry into the AiChE ChemE Car Competition.In addition, I developed a novel stopping mechanism by applying reaction chemistry coupled with an integrated photosensor for use in the model car. In the first reaction, aqueous iodide is produced upon the reaction of potassium iodide, potassium bromate and hydrochloric acid. The first reaction proceeds as follows:Reaction 1 (Slow)6 I-(aq) + BrO3-(aq) + 6 H+ → 3 I2 (aq) + Br-(aq) + 3 H2OThe second reaction consisted of the aqueous iodide produced in the first reaction dissociating upon reaction with sodium thiosulfate to produce iodine ions which would then bind with the starch indicator present in the solution to reveal the blue color visible when the reaction reaches completion. The second reaction in the overall reaction for the chemical clock is as follows:Reaction 2 (Fast)I2 (aq) + 2 S2O32-(aq) → 2I -(aq) + S4O62-(aq)The method in which the reaction would be implemented into an integrated chemical clock stopping mechanism was based upon the kinetics of the reaction. Due to the fact that the first reaction is the slow reaction, Reaction 1 is the rate-limiting step of the overall process. The overall rate equation for the reaction is a 4th order reaction as follows:Rate = k[I-][BrO3-][H+]2Rate: s-1k: L4/(mol4 *sec)[X]: mol/LIn this equation, the time it takes for the solution to change color from clear to blue is represented by the inverse of the Rate of the reaction. The rate is in turn related to the initial concentration of the three reactants of the rate-determining step of the overall reaction as well as the specific reaction rate constant, k. The value of k is directly based upon the temperature of the system and is independent of the concentrations of the initial reactants.
