On Thursday, May 30th, UConn’s GK-12 program hosted the second annual Engineering Design Challenge Competition, involving student teams from Connecticut’s Technical High School System, at the Storrs campus. The theme of this year’s competition was “Reverse Engineering Egg Crash Car.”

In the good-natured competition, the student teams were required to apply core engineering principles in a deceptively simple, fun and engaging way while pitting their engineering knowhow against that of other Tech School students. The participating teams were the top performers in contests held at their home Tech Schools.

In the Egg Crash Car competition, the teams were charged with building a racecar – using only the materials provided – capable of safely transporting an uncooked egg through a variety of challenges without the precious cargo breaking.

Among the materials available were Ziplock® bags, wheels, balloons, straws, pom-poms, mouse traps, fishing line, tape, poly-fill stuffing, cotton balls and rubber bands. These raw materials produced a variety of vehicles, from sleek rectangular entries to zany-looking “Mad Max” style vehicles adorned with cotton-ball armor. For each vehicle, it was stipulated that the egg “passenger” had to be removable.

The GK-12 Fellows designed three rigorous tests for the vehicles: a rear impact test, in which a suspended wooden mallet was released from three different angles into the rear of the vehicle; a rollover test, in which vehicles were released at different angles from the top of a four-foot plane; and a head-on collision test, in which CO2 canisters were attached to the rear of each vehicle as a propulsion system that carried the vehicles into a cinderblock wall. For each test, the aim was to keep the vehicle and its egg cargo intact. Other criteria included the vehicle production costs, speed and structural integrity.

In the end, the Tech School students enjoyed a fun day of friendly competition and came away with a better appreciation of core engineering concepts such as performance-based testing, tradeoffs between material cost and quality and the iterative and challenging nature of the design process.

The competition brought together teams from the Academy of Engineering and Green Technology, Howell Cheney Technical High School, Harvard H. Ellis Technical High School, E.C. Goodwin Technical High School, Ella T. Grasso Southeastern Technical High School, Norwich Technical High School, A.I. Prince Technical High School, Vinal Technical High School, and Windham Technical High School.

The teams – along with fellow students who did not compete – were mentored throughout the 2012-13 academic year by UConn Engineering doctoral candidates who are committed to helping introduce engineering concepts in Tech School classrooms. The 2012-13 GK-12 Fellows included Juan Pablo Correa Baena (Environmental Engineering); Lu Han,  Andrea Kadilak, Joseph Parisi and Rebecca Rubinstein (all in Chemical Engineering); Justin Roller and Michael Zilm (Materials Science & Engineering); and Lou Bachenheimer and Nick Curtis (Mechanical Engineering).

The GK-12 (Graduate STEM Fellows in K-12 Education) program is an innovative educational program sponsored by the National Science Foundation.  It aims to provide teaching resources (in the form of graduate students in the engineering sciences) to classrooms in the state of Connecticut Technical High School System. Dr. Doug Cooper is the Principal Investigator of UConn’s GK-12 program.

Dr. George Bollas Receives ACS PRF Doctoral New Investigator Award

By Jayna Miller

bollasgeorge_wCDr. George Bollas, an assistant professor in the Department of Chemical and Biomolecular Engineering, is the recipient of a prestigious ACS Petroleum Research Fund Doctoral New Investigator Award. The ACS PRF programs support innovative research in the petroleum field and promote the development of promising engineers and scientists. The award program provides career opportunities to young faculty and their undergraduate and graduate students by supporting advanced scientific research. The goals of the American Chemical Society Petroleum Research Fund are to support fundamental research in the petroleum field and develop the next generation of engineers and scientists through the support of advanced scientific education.
Dr. Bollas’ research project will explore aspects of Fischer-Tropsch Synthesis selectivity. The Fischer-Tropsch process is a collection of chemical reactions that provide a means of producing transportation fuels from carbon monoxide and hydrogen, a combination referred to as synthesis gas. This reaction also produces excess hydrocarbon products in addition to materials for fuel, so there remains a need to make this process more selective.

Through Dr. Bollas’ research, it may be possible to significantly improve the selectivity of this process to make the synthesis of fuel through Fisher-Tropsch more efficient and economical. Dr. Bollas and his research group plan to examine novel catalyst synthesis methods that enhance the selectivity of Fischer-Tropsch Synthesis (FTS) towards intermediate-chain length hydrocarbons, particularly synthetic gasoline.

The benefits of making Fischer-Tropsch a more efficient and less centralized process are energy independence and security. In addition, the vast unexploited resources of natural gas found recently in the US make natural gas a major source for energy and fuels production. Dr. Bollas’ new experimental work will provide the capability to expand research exploring alternative fuels and efficient processes at the CBE Department and in the Center for Clean Energy Engineering.

Dr. Bollas is a process design expert and winner of the prestigious NSF CAREER Award and the ACS PRF DNI Award. His research focuses on biomass pyrolysis, coal and biomass to liquids, Fischer-Tropsch synthesis, chemical-looping combustion, and waste to energy processes.

CBE Launching Revised Capstone Senior Design Program

By Jayna Miller

The Chemical & Biomolecular Engineering (CBE) Department is pleased to announce the launch of a revised Capstone Senior Design program this fall 2013. In this new format, each faculty member will be advising one or two capstone design projects over the entire academic year.

Prof. Leslie Shor, building on the recent successes of Prof. Dan Burkey in formulating this new format, will be leading the effort for the department. Professor Shor is a Northeast Utilities Assistant Professor of Environmental Engineering Education, and currently leads the Engineered Microhabitats research group.

Professor Shor will be chairing a “Capstone Design Governance Committee,” which will propose guidelines for Capstone Design projects, create templates for project descriptions and general project criteria, and work with faculty to ensure proposed projects meet the criteria.  Working with Burkey and Prof. George Bollas, the committee will also create milestone and evaluation rubrics for the faculty and students to follow, and produce an “example design projects catalog,” which can be used to recruit industry sponsors. The overarching goal is to help the department provide the best design experience for students and our industry partners.

http://cbe.engr.uconn.edu/wp-content/uploads/sites/1814/2013/06/capstone_cbe2013-400x300.jpgIn Capstone Design, our seniors are mentored by chemical engineering faculty and industry sponsors as they apply engineering fundamentals and tools to solve practical engineering problems. Students use this experience to develop teamwork and communication skills as they tackle their open-ended, real-world challenges. They learn about the principles and practices of design, setting priorities, project management, ethical and economic decision making, intellectual property, oral and written communication, all as they evaluate their design from a technical, economic, safety, and environmental perspective.

The department is actively seeking industry partners to propose and support a student project. For more information, please visit: http://www.cbe.engr.uconn.edu/undergraduate-program/capstone-design and learn how to join our team.

UConn Engineering Honors John (Jack) Prior

prior2013During a gala event on May 2 at the Storrs campus, the School of Engineering honored 10 exceptional alumni and friends as 2013 inductees into the UConn Academy of Distinguished Engineers. Nearly 100 attendees helped to honor the new inductees, each of whom spoke of the profound influence of UConn Engineering in shaping their careers.  One inductee was an alumnus of the Chemical Engineering department, John Prior.

John (Jack) Prior graduated from UConn in 1986 with a B.S. in Chemical Engineering, and then went on to earn a doctorate of science (Sc.D.) in Chemical Engineering from MIT, focusing his research on monitoring and controlling bioreactors for the production of biopharmaceuticals.

Jack’s current position is Senior Director for Bioprocess Engineering at Genzyme, where he oversees a team of 14 engineers responsible for improving the manufacturing processes  for these and other biopharmaceutical compounds that can be incredibly challenging to produce.

Jack’s work often places him in the “front lines” in addressing critical challenges. For example, he led company efforts to identify and correct the cause of a Thymoglobulin production challenge at the company’s facility in France in 2007. His efforts enabled patients to continue to receive this life-saving therapy. In 2008, he led efforts to understanding and address product comparability issues that had previously delayed the introduction of adult treatments for Pompe’s disease in the US.  Jack also played a key role the troubleshooting effort surrounding a viral contamination episode the company experienced in 2009.

In addition to Jack’s important management and manufacturing technology development role in the biopharmaceutical industry, he has given back to UConn directly by serving as a member of the Chemical Engineering Industrial Advisory Board since 2006.  In this capacity, he generously gives his time to provide critique, guidance, and support to the Chemical Engineering program. The CBE department would like to extend its congratulations to Jack Prior for his induction into the UConn Academy of Distinguished Engineers.
