Through the Summer Research Academy, four of our research students got the chance to promote our research lab to undergraduate students who were interested. They talked about their own personal experience with research as well as the projects they are working on. The attendees got a chance to learn about the equipment and posters in the lab as well. Also one of our research students, Khanh Vo, presented one of our posters at the Research Showcase.
Thank you Taiason Cole, Khanh Vo, Ryan Hoover, and Eric Barker
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

Congratulations to our three lab members who were awarded Summer Undergraduate Research Fellowships by UCF. Taiason Cole was awarded under Track 1, Emerging Fellow, and will be analyzing x-ray diffraction data as part of an investigation to characterize additively manufactured Inconel 718. Eric Barker was awarded under Track 2, Fieldwork Fellow, and will be working with NASA’s Glenn Research Center for research on a new thermal barrier coating called PS-PVD. Brooke Sarley was awarded under Track 3, Publishing Fellow, and will be preparing a manuscript for publication based on research she has been conducting for several semesters on additively manufactured Inconel 718.
Lab members Eric Barker, Estefania Bohorquez, Jonathan Hernandez, Ryan Hoover, Lin Rossmann, and Brooke Sarley presented three research posters at the Showcase for Undergraduate Research Excellence (SURE) at UCF. SURE provides the perfect opportunity for UCF undergraduates from all disciplines to present their research and projects to the rest of the UCF community.
Eric Barker and Johnathan Hernandez presented on “Effects of Functionalization on Hybrid Carbon Reinforced Polymer Composites through Photoluminescence Spectroscopy.”
Estefania Bohorquez and Ryan Hoover presented on “Investigation of the Effects of Thermal Barrier Coatings via Piezospectroscopy.”

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.

Members of our laboratory volunteered at a Camp Connect event at UCF. Students, from 8th to 10th grade, came from surrounding schools to engage in activities that focus on STEM related subjects. Our members oversaw an activity showing the importance of light weight structures with high strength to weight ratios. A presentation was given by our group on space structures as examples of why the strength to weight ratios are important. Following a brief presentation on aerospace structures, the students competed to build a solar sail mast with the highest strength to weight ratio.

The trip to CNM was part of a collaboration with CNM scientists to develop nanoscale experiments to investigate the fundamentals of the stress sensing behavior for varying alumina nanoparticles. Using electron beam (E-beam) lithography, “nanobuckets” were created in Si wafers of various sizes and filled with an epoxy/alumina nanoparticle mixture.
The sample development will pave the way for experiments using an Atomic Force Microscope (AFM) within a confocal backscattering setup for measuring Photo-luminescence from the samples. These fundamental studies will investigate a range of particles, quantifying a multitude of important nano-composite properties such as interface strength, load transfer, and piezospectroscopic properties
