Research Assistant

Fabrication of Ordered Pits on Aluminum and Aluminum Alloy 3003 Utilizing Colloidal Crystal Templating (Xerox collaboration) (1/2008 – 5/2010)

Research and analysis of the possible method for producing uniform pits array on inkjet printing drum of copier machines were conducted to increase its process efficiency. Samples of interest include pure aluminum and aluminum alloy 3003. Electrochemistry techniques, theory, and application were applied to produce the results. Surface of the substrates were electropolished or mechanically polished. SEM, AFM, QCM, and JMP were used to complete result analysis.

• Successfully developed a new method for fabricating ordered micro-porous pits arrays on aluminum and aluminum alloy 3003 utilizing colloidal crystal method for solid-ink based printer.

• Developed method was practical, efficient, and could be applied to possible industrial process. Its application might not be limited to flat surfaces.

Deposition of Copper from Aqueous Solutions onto Oxide-base Metal Interface

(1/2010 – 8/2010)

Novel copper deposition technique based on mass transfer utilizing electrochemical techniques was developed and experimented for successful implementation onto oxide-base metal interface (aluminum and titanium).

• Validated the novel copper deposition technique utilizing galvanic displacement by the use of Quartz Crystal Microbalance (QCM) and the use of imaging equipment (SEM, AFM). Copper was successfully deposited with the thickness in the order of hundreds of nanometer.

Development of Corrosion Initiation Sites in Aluminum Alloys 2024

(1/2007 – 1/2008)

Effect of the corrosion initiation sites on aluminum alloy 2024 and its implication toward subsequent product application was studied utilizing electrochemistry techniques.

• Confirmed the hypothesis of the evidence of the sub-micron initial growth of pits in aluminum alloy 2024 utilizing series of etching and imaging experiments.

Teaching Assistant

Chemical Engineering Lab II (ChE 426)

(1/2009 – 5/2009)

• Instructed chemical engineering senior lab courses (ChE 426)

• Provided assistance for instructor by administering laboratory work and grading report

• Helped 30 students to understand course materials for the heat and transfer, distillation, and chemical reactor performance

PROJECTS

Styrene Production Facility (12/2007)

Preliminary design of a new grass roots facility was planned to increase styrene production. CAPCOST, HENSAD, and HYSIS were utilized to generate the analysis and results. Principles of fluid mechanic, thermodynamic, and mass transfer were applied.

• Successfully designed and implemented MUMNE network (multiple heat exchanger network configurations) utilizing HENSAD

• Created and realized a new catalyst design that reduce reactor volume configuration, thus reduced the cost of production while improving efficiency. Production were successfully increased by 3.4% with internal rate of return (IRR) of 15.94%

Dynamic Modeling of Stirred Tank Heater (4/2007)

Developed a design to improve stability of tank heater system utilizing process control principle.

• Using MATLAB and Simulink, stability of the tank heater system was simulated and considerable improvement was discovered.

Pipeline Configuration of Plant Design (4/2006)

Suitable pipeline configurations with centrifugal pump were designed with the principle of fluid dynamic to improve the plant dynamic.

• Successfully calculated and implemented pipeline size, length and configuration, including the PFD and P&ID diagrams.

Production of Chlorinated Polyvinyl Chloride (11/2005)

Planned and designed a process for producing chlorinated polyvinyl chloride (CPVC) utilizing mass transfer principle
