SeungYeon Kang, Ph.D. presented a seminar Friday, March 6, over, “Advanced Laser-Materials-Processing Techniques for Nanofabrication of Functional Materials and Energy Harvesting Devices.” Dr. Kang is a Program Manager for NSF’s SHAP3D additive manufacturing center at the University of Connecticut.
Abstract: Increasing number of novel materials, structures and device are being designed every day to revolutionize our future. Accordingly, new fabrication methods to complement the designs must be developed for actual realization of the devices. In this talk I’ll start by discussing the use of ultrafast lasers for advanced materials processing techniques and the significance of developing new nanofabrication methods for cost-effective manufacturing and rapid prototyping with high accuracy. The focus of my talk will be on a novel direct laser writing technique that enables fabrication of 3D metal-dielectric nanocomposite structures of tunable dimensions ranging from hundreds of nanometers to micrometers. This true 3D patterning technique utilizes nonlinear optical interactions between chemical precursors and femtosecond pulses to go beyond the limitations of conventional fabrication techniques that require multiple postprocessing steps and/or are restricted to fabrication in two dimensions. The first part of the talk will end with a further discussion on possible applications including metamaterials, graphene-based devices and etc. In the shorter second part of the talk, I’ll introduce a relatively new material of research interest called piezoelectrochemical materials and another advanced laser-materials-processing technique that utilizes laser induced forward transfer (LIFT). I’ll end with a discussion on how one can use these two research areas to develop energy harvesting devices that convert ambient mechanical energy into electrochemical energy.

On Friday, February 14th, Dr. Jeongmoo Huh gave a presentation over, “Micro Propulsion Systems for the Next Generation Space Missions.” Dr. Huh currently works in the Space Engineering Department in the Faculty of Aerospace Engineering at Delft University of Technology as a visiting researcher.
Abstract: Many miniaturized satellites have recently been launched and proved the feasibility of distributed space systems in space missions with improved revisit time, the time elapsed between observations by satellites, at an extremely low cost. Most preliminary small-scale satellites such as CubeSat and PocketQube, however, were either not equipped with a micro-propulsion system for its altitude/orbit control or not ready for various space missions due to inherent theoretical performance limitations of space propulsion systems that currently exist as well as limited performance achievement of micro propulsion systems. Not only normal operation of miniaturized satellites but also the next generation space mission using CubeSat/PocketQube will not be feasible without successful downsizing of space propulsion systems and their performance improvement.
The seminar will start with general principles of several chemical rockets and difficulties of downsizing of chemical rockets, and report how a chemical rocket was successfully miniaturized including a photolithography process, a MEMS (Micro-electro-mechanical Systems) based fabrication technology, and catalyst manufacturing process as well. Performance of thruster generation and propellant decomposition efficiency of 50 mN class MEMS-based monopropellant micro thrusters will be discussed based on experimental data showing how much performance was improved by using a blended propellant and regenerative micro cooling channels in micro scale thruster systems.
This will be followed by an introduction to electrospray micro colloid propulsion, one of space electric propulsion systems, which has arguably the highest specific impulse performance, up to a range of 1,500-7,000 s depending on electric power supplied. The different nature of the working principle of the system and its performance characteristics compared with chemical one will be identified. Pros and cons of chemical and electric propulsion systems will be discussed with inherent performance limitation of both propulsion systems, and a new system configuration for space micro propulsion will be suggested to meet the performance requirement of miniaturized propulsion systems for the next generation space missions, an interplanetary mission of miniaturized satellites.
Biography: Dr. Jeongmoo Huh currently works in Space Engineering Department in the Faculty of Aerospace Engineering at Delft University of Technology (TU Delft) in the Netherlands as a visiting researcher starting from July 2019. In Delft, He’s working on high energetic gel phase novel propellant development for space propulsion applications. Before joining the group, he worked as a postdoctoral researcher at Queen Mary, University of London (QMUL), in the UK from April 2017 to June 2019 participating in an electric propulsion project funded by the EU. The project was about high-performance low-cost disruptive propulsion technology using electrospray colloid propulsion for small-scale satellite applications. There was a consortium for the project and it was composed of a university, QMUL, and three different space-related companies, AirBus in the UK, NanoSpace in Sweden, and SystematIC in the Netherlands. The successful outcome is now on its way to commercialization. Dr. Huh stayed in Daejeon, South Korea for about 5 years from Feb 2012, for his graduate course and one year of postdoc experience. He received an M.S./Ph.D. degree in the Department of Aerospace Engineering from Korea Advanced Institute of Science and Technology (KAIST) in Daejeon in Feb 2016. For his Bachelor’s degree, he studied in the Department of Aerospace and Mechanical Engineering at Korea Aerospace University, Goyang, South Korea, from March 2008 to Feb 2012.

Many projects from the Spring 2019 Capstone Fair made a lasting impact on the community. Each group did an amazing job of solving a real-world problem and presenting their poster project at the fair.
The highlighted groups from last semester’s Capstone fair include the the Iron Cross Experience, Introducing Girl Scouts to STEM project, the Electronics Assist Equipment project, the B-52 Spoiler Fixture Redesign, Sooner Off-Road, and groups that worked with Baker Hughes and Schlumberger.
The members of The Iron Cross Experience (pictured below), Jared Alex, Garrett Parkhurst, Bryan Boone, Covey Barlow, and Isaac Pryzant, were tasked with introducing patrons at the Science Museum Oklahoma to gymnastics with an interactive and educational exhibit. The project was added to the Science Museum this summer and patrons can use the interactive game to perform an iron cross. The group fully integrated electronics to provide an interactive experience, manufactured the X-Frame graphics stand to match aesthetic of the ring stand, displayed dynamic graphics and feedback for the user when interacting with the exhibit, and did troubleshooting and maintenance guide for the ring stand, electronic components, programming, and X-Frame.
The Electronics Assist Equipment members, Pranav Mohan, Ashley Medice, Gerald Lance, and David Carris (pictured below) were featured on KOCO 5 for their work with 11-year-old Christopher Ramirez, a young man who does not have use of his arms or legs due to a muscle disorder. The group created tools to help him independently read a textbook, use a computer, use a phone, and play Xbox games. They placed first in prototype design at the capstone poster fair.
Emma Hensley, Moises Martinez, Nicole Reed, and Dakota Walters were members of the “Introducing Girl Scouts to STEM” project (pictured below). The group worked closely with Girl Scouts to teach them about simple machines and women in engineering. They encouraged the involvement of Girl Scouts in STEM by creating an educational experience in the space provided that could be understood by all Girl Scouts of all knowledge bases. Through the creation of a dumbwaiter, they were able to teach the girls about how to discover, connect, and take action.
The “Setup to Evaluate Debris-Scrapper Ring Design” project (pictured below) placed second overall and received first place in experimental and testing. The team worked closely with Schlumberger to implement design and prototyping of experimental setup to reciprocate scraper rings to failure in a debris-laden fluid. Scraper rings were evaluated in dynamic high-pressure and temperature applications with varying concentrations of debris. The group successfully met the design requirements and all systems were integrated. The group members were Courtney Holloway, Nicholas Son, Alexander Nagy, Abel Rivera, and Haydn Kirkpatrick.
The “Test Bench for ESP Seal Section Permeability” project (pictured below) worked with BHGE and received second place in experimental and testing. This team worked with Baker Hughes to solve the problem of the contamination of motor oil. Well-bore fluids appeared to be contaminating motor oil within the bladder section. The group addressed the permeation through bladder materials, one of the possible causes of motor oil contamination. The team was able to address the concerns and create a prototype for the company. Group members were Logan Vitello, Travis Wilbanks, Ifeanyi Ijioma, Marshall Thorpe, and Logan Roys.
Sooner Off-Road (pictured below), had objectives to reduce the weight of the Sooner Off-Road vehicle by 50%, increase performance (acceleration and top speed), increase tunability (easier and more options), and decrease cost (in house manufacturing). They were able to decrease the weight from 8 pounds to 3.01 pounds, increase the acceleration from 5 sec/100ft to 4.5 sec/100ft, increase tunability through preload shims, and decrease cost from $2,200 to $250.
The B-52 Spoiler project group members (pictured below), were given the task to consolidate seven spoiler fixtures down to three or fewer fixtures. The assembly fixtures are used to assemble the metal structure and skin of the spoilers with proper alignment. This group exceeded the target objective and consolidated down to one fixture.
Sooner Off-Road (Matt Muhlinghause, Haley Ricks, and Devin Prochniak) and The B-52 Spoiler Fixture Redesign (Morgan Wolfe, Tyler Thibodeaux, Alexandra Arment, Roshan Mathews, and Alex Mudd) tied for first place overall!
