Gregory Freihofer wins 2nd place at the SAMPE CAMX student paper competition
We are pleased to announce that three of our current and former lab members have published their paper “Silane functionalization effects on dispersion of alumina nanoparticles in hybrid carbon fiber composites” in the journal of Applied Optics.
Current and former lab members Alex Selimov, Sanjida Jahan, and Eric Barker worked in collaboration with scientists at Imperial College London, studying the effects of silane treatments on the dispersion properties of alumina nanoparticles in composite materials.
Lab member Zachary Stein has presented a poster on the research he has been conducting this summer as part of his participation in the Summer Undergraduate Research Fellowship (SURF), which he was awarded in April. Zac has been studying the effects of sand ingression on thermal barrier coatings and the research presented was on some initial analysis of the experiments conducted at Argonne National Laboratory this July.
Zac presented at the Summer Research Academy’s “Meet Student Researchers: Poster Showcase.” The Summer Research Academy introduces its participants to academic research and how to get started on conducting research themselves.
Lab member Debraliz Isaac-Aragones spent the summer at Purdue University in West Lafayette, Indiana participating in the Summer Undergraduate Research Fellowship (SURF) program. Her research focused on alternative thermal management solutions for electronic devices using thermal interface materials. She investigated the conduction pattern of particle-filled polymer composites using infrared microscopy. The experimental results were validated with both simulation software and theoretical relationships found in literature. She presented her summer’s work at the 2018 SURF Symposium.
Debraliz also participated in a program called Pathways that provided additional mentoring, networking, and professional opportunities for underrepresented students interested in pursuing a PhD. “We had several informal meetings where a small group of students and I engaged in discussion with faculty and graduate students. It has been a valuable experience to ask questions first-hand about what life is like in and after graduate school.” Overall, SURF gave her a better outlook on her future as a researcher.
Four students, three of them members of our lab, were part of a field team who recently conducted experiments at Argonne National Laboratory (ANL). Experiment campaigns at ANL are rigorous and demanding, but highly rewarding. The students reflect on their experience.
Matthew Northam, graduate student:
“I am, overall, very happy with how this year’s ANL trip went. Our group hit a few road blocks during the XRD experimentations, as to be expected, but everyone was constantly focused and determined to work together and get around the problems. Because the beam went down, we had to do twice as much work in the last day of experiments in order to reach our goals, but we came up with a new sample holder design and became more efficient regarding data collection and achieved our goals and then more. I couldn’t have asked for a better group of dedicated people to work with.”
Lin Rossmann, graduate student:
“Zac was our MVP, hands down. It’s impressive enough for an undergrad to be in charge of their own study, but not only did he do that, he also took the lead on our data analysis. With some help from the beamline scientists, he was able to analyze some of our XRD data to get strain information while we were still there. Being able to analyze data while the experiment is still ongoing is very important, because then you can be confident that your collection parameters are good, and if they’re not, you have time to fix it.”
Peter Warren, graduate student:
“To be able to go to Argonne National Lab and conduct experiments was an amazing and transforming experience. The entire trip was very enlightening, and was filled with excitement. I feel extremely lucky and blessed to have been a part of this trip. Being able to interact with some of the most brilliant scientists in the world felt quite surreal. This trip has given me both motivation and encouragement to continue my academic career in engineering.”
Zachary Stein, undergraduate student:
“It was definitely challenging to run my own study and ensure the best possible data was being produced, but the rest of the team was there assisting me along the way. Teamwork and on-the-spot problem solving is essential, meaning everyone must know each other’s projects as well as their own to be able to contribute fully. It was a week of important life lessons, but the most important of all is to keep a persistent, determined, and focused attitude so that no obstacles can stand in the way.”
We are proud to announce that Estefania Bohorquez has won second place in the Best Poster Award at Thermal Barrier Coatings V, a conference held by Engineering Conferences International (ECI). Her poster, titled “Raman studies on EB-PVD 7 wt% yttria-stabilized zirconia coatings with CMAS deposits,” is the result of a collaboration with the German Aerospace Center (DLR).
The conference was held in Irsee, Germany from June 24 – 29, 2018. This is the first time the lab has been represented at this event, which occurs every 4 years and is highly competitive.
The collaboration with DLR developed from the NSF International Research Experience for Students (IRES) program. As part of IRES, Estefania was one of a group of students who spent a summer conducting research at a DLR facility. To read more about IRES, click here.
A team of researchers under Dr. Seetha Raghavan and Dr. Ranajay Ghosh has just returned from an experimental campaign at the Advanced Photon Source (APS) at Argonne National Laboratory (ANL). The experiments encompassed three different projects, each making use of the high-energy synchrotron x-rays of the APS to investigate the microstructure and physical properties of thermal barrier coatings (TBCs). TBCs are used to protect components in gas turbine engines from the extreme heat of combustion, and the team is contributing to their advancement in three areas.
The project led by graduate students Matthew Northam and Lin Rossmann encompasses investigating the properties of thermal barrier coatings produced by plasma-spray physical vapor deposition, a new and promising manufacturing method that may be more customizable and cost-effective than the current techniques in industry. This project is in collaboration with Dr. Bryan Harder of NASA’s Glenn Research Center; Matt and Lin visited Glenn in the spring semester to manufacture and begin testing these samples with Dr. Harder.
Postdoctoral fellow Sandip Haldar and graduate student Peter Warren led a Department of Energy-funded study on thermal barrier coatings doped with the rare earth element europium. Rare earth elements fluoresce when stimulated with certain wavelengths of light, and the duration of this fluorescence is dependent on temperature. A major objective of the DoE project is to implement rare-earth-doped TBCs such that the temperature inside an engine can be measured non-destructively and optically. The study performed at ANL will provide insight into how the addition of europium affects the mechanical properties of the TBC.
Undergraduate student Zachary Stein led a study investigating the effects of sand and ash on thermal barrier coatings. Fine debris like sand, dust, and ash causes damage to the TBCs in aircraft engines and shortens the engine lifetime, so understanding the nature of its effects is important to improving future coatings. This project is in collaboration with the German Aerospace Center (DLR), and DLR postdoctoral fellow Dr. Ravi Naraparaju joined the team for a day to discuss the project with Zac and Dr. Raghavan.
The team members from Raghavan Research Group were postdoctoral fellow Sandip Haldar, graduate students Matthew Northam and Lin Rossmann, and undergraduate student Zachary Stein; graduate student Peter Warren is a member of Dr. Ghosh’s research group. The team thanks the scientists at Sector 1 of the Advanced Photon Source who helped them: Dr. Jonathan Almer, Jun-Sang Park, Peter Kenesei, and Ali Mashayehki.

The 2018 IRES team, with help from volunteers, hosted activities for UCF STEM Day. This year they had two groups of students; one from middle school and one from high school. Each group rotated through different stations where they learned about topics on heat transfer, spectroscopy, and gas turbine engines.
At the heat transfer station, the students learned about different heat transfer mechanisms through the use of thermochromic materials. A volunteer did a demonstration with thermochromic sheets made from thermochromic liquid crystals to show its color variation in response to temperature change.
At the next station, the students learned about non-destructive methods of testing through a spectroscopy demonstration. An IRES participant prepared spectrometers for the students to use to see the different color spectrum when exposed to various sources of light.
The final station consisted of posters showing a deconstructed gas turbine engine and “engines of the future”. One of the goals of this IRES STEM activity was to promote international collaboration through a language learning exchange. The IRES participants thought the students some technical and non-technical words pertaining to gas turbine engines in German. In addition, they discussed the functions of engines and the importance of using thermal barrier coatings to allow higher turbine inlet temperature, which enhances the thermal efficiency.
At the end of the activity, the IRES participants asked the students questions on what they had learned and gave out prizes for correct answers. Overall, the students really enjoyed the activity!
Special thanks goes out to all of our volunteers and the IRES students for coming together and making this activity possible.

Camp Connect is a week-long day camp that introduces high school and middle school students to various engineering disciplines at the University of Central Florida. For Camp Connect we hosted “Shedding Light on Damage in Aircraft Structures”. We had 4 groups of 20 students, meaning we met up to 80 students in total. We started off by educating the students about spectrums and how we use light to test our materials and study their mechanical properties. Afterwards the students got into group of four and created their own spectroscopes. Spectroscopes are a tool used to split the wavelengths of lights into the colors that make them up also called spectrums. Once they created the spectroscopes we allowed the students to look at various light sources through the spectroscopes and record their observations. They got to look at fluorescent, incandescent, projector, computer, and their cellphone lights. Following the observations, they played a matching game where they compared different spectrums to the lights they observed and see how many they could match up. Two groups got all five spectrums correct. It was a great activity and the kids had a great time learning about light and understanding how it can be used to tell us about our materials.
Special Thanks to Taiason Cole, Khanh Vo, Sanjida Jahan, Ryan Hoover, and Eric Barker

As part of STEM Day at UCF, the IRES students, with help from other lab members, hosted two activities for groups of high school and middle school students. In one activity, a gas turbine engine was deconstructed into three different sections. The kids learned about how gas turbine engines work at the individual stations that highlighted the engineering of each section, with the help of a 3D-printed cutaway model (borrowed from the UCF chapter of ASME). To emphasize the international aspect of science and engineering, we taught them some common and technical words in German, and encouraged them to teach us relevant words in the languages they knew. The kids translated a total of 23 words in over 6 different languages!
In the second activity, the kids learned about spectroscopy and each built a simple spectroscope, which they got to take home with them. Spectroscopes are a simple tool to introduce kids to the field of spectroscopy, which is a powerful diagnostic tool for engineers as well as a scientific tool. One of our lab teams is using a type of spectroscopy called photoluminescent piezospectroscopy to investigate the effects of sand ingression on the coatings of turbine blades.
The kids enjoyed themselves and learned a bit, and the volunteers have a fun time as well.
A special thanks to our volunteers: Sanjeev Ballapuram-Murali, Taiason Cole, John Hatchitt, Ryan Hoover, Cesar Lopez, and Brooke Sarley, and IRES students Estefania Bohorquez, Debraliz Isaac-Aragones, Owen Pryor, and Lin Rossmann.
