Research Assistant, NanoEnergy Lab, Mechanical Engineering Dept., WPI March 2015-Present

● Designed experiments, made samples, ordered chemicals, installed and maintained the lab for 3 projects

● Applied the unique synthesis technology (flame synthesis) to grow semiconductor nanowires thin film

● Synthesized thin film transitional metal semiconductors as novel photoanode materials by CVD or PVD

● Identified morphology with SEM and measured solar absorption efficiency of nanoparticals in PEC test PROJECTS:

Independent research: Conversion of tungsten oxide to tungsten disulfide, WPI March 2015 -Present

● Operated spin coating of seed layer, grew and annealed WO3 nanowires on metal foils in flame synthesis

● Converted WO3 nanowires into WS2 nanotubes and kept their shape in the 3-zones tube furnace by CVD

● Controlled and optimized growth of WS2monolayers by calibrating H2, N2, Ar through the tube furnace

● Created one sulfur bubbler that can supply constant S gas with hot plate, thermocouple and heating tape Team project: Growth of tungsten oxide nanowires by PVD in vacuum system, WPI Jan 2016-Present

● Leaded this project and taught one undergraduate student how to use the tube furnace and PVD method

● Built vacuum system by installing a pressure gauge and connected to vacuum pump through quartz tube

● Put pure WO3 powder at desired position in furnace and calibrated N2 as carrier to deposit on Si wafer Team research: Coating of monolayer tungsten disulfuide on foils by CVD,WPI Sept-Nov 2015

● Cleaned the thin flim surface using IPA/Acetone/DI water solution and coated seed layer by spin coating

● Measured temperatures inside tube furnace when it’s on and achieved desired temperatures and positions

● Pulled precursors (WO3 and S powder) to the desired positions, vaporized and then deposited on wafers Team project: Improving flame resistance of Nylon6/PU composites, WPI March 2016-Present PUBLICATION:
