Water activist honored with OU International Water Prize

Martha Gebeyehu, coordinator for Ethiopia’s Water Expertise and Training Centre, was recently named the recipient of the 2019 International Water Prize. A panel of water experts from around the world selected Gebeyehu for her ongoing commitment to empowering and training people to manage their own water and sanitation. 

“Martha is serving some of the world’s poorest in some of the most rural and remote regions of Ethiopia,” said Shauna Curry, chief executive officer of the Centre for Affordable Water and Sanitation Technology. “Her belief in the power of people to bring change to their own homes led to her work in the area of household water treatment. This quickly broadened to the entire area of water, sanitation and hygiene with low-cost technology that people can implement themselves.” 

While pursuing a master’s degree in business administration, Gebeyehu became the first water quality analyst for the Ethiopian Kale Heywet Church Development Commission implementing safe testing practices and procedures. Her growing knowledge, coupled with an eagerness to share her expertise, led her to initiate the development of a laboratory and facilitate the first water quality workshops. She has personally educated and trained over 1,000 individuals for the WET Center. Now she serves as WET Center coordinator, guiding WAter, Sanitation and Hygiene projects from conception and implementing research projects to effectively link government water policy to rural communities. 

“I became interested in working with WASH through a strong understanding of the technical aspects of water quality and a drive to share my knowledge with others,” says Gebeyehu. “Ultimately, I am dedicated to serving those in need so that they can reach their full potential and well-being.” 

Sponsored by the University of Oklahoma Water Technologies for Emerging Regions Center, the International Water Prize is one of the first and largest prizes dedicated solely to the field of water supply and sanitation in remote areas of emerging regions. The award-winner is selected through a nomination process and honors an individual that has made significant contributions in these areas, particularly communities in rural or remote regions. 

Gebeyehu will formally receive the OU International Water Prize and give the plenary lecture at the sixth Biennial OU International WaTER Conference, scheduled for Sept. 16-19, 2019. The conference includes local and international speakers, breakout sessions and poster and paper sessions in the fields of social entrepreneurship, behavior change, water technologies, climate change and hydro-philanthropy in the developing world.

OU Researcher Determines Catalytic Active Sites Using Carbon Nanotubes

University of Oklahoma researcher Steven Crossley and his team have devised a novel method to determine the cause of catalytic activity.

NORMAN – Catalytic research led by University of Oklahoma researcher Steven Crossley has developed a new and more definitive way to determine the active site in a complex catalyst. His team’s research was recently published in Nature Communications.

Catalysts consisting of metal particles supported on reducible oxides show promising performance for a variety of current and emerging industrial reactions, such as the production of renewable fuels and chemicals. Although the beneficial results of the new materials are evident, identifying the cause of the activity of the catalyst can be challenging. Catalysts often are discovered and optimized by trial and error, making it difficult to decouple the numerous possibilities. This can lead to decisions based on speculative or indirect evidence.

“When placing the metal on the active support, the catalytic activity and selectivity is much better than you would expect than if you were to combine the performance of metal with the support alone,” explained Crossley, a chemical engineer, Teigen Presidential Professor and Sam A. Wilson Professor within the Gallogly College of Engineering. “The challenge is that, when you put the two components together, it is difficult to understand the cause of the promising performance.” Understanding the nature of the catalytic active site is critical for controlling a catalyst’s activity and selectivity.

Crossley’s novel method of separating active sites while maintaining the ability of the metal to create potential active sites on the support uses vertically grown carbon nanotubes that act as “hydrogen highways.” To determine if catalytic activity was from either direct contact between the support and the metal or from metal-induced promoter effects on the oxide support, Crossley’s team separated the metal palladium from the oxide catalyst titanium by a controlled distance on a conductive bridge of carbon nanotubes. The researchers introduced hydrogen to the system and verified that hydrogen was able to migrate along the nanotubes to create new potential active sites on the oxide support. They then tested the catalytic activity of these materials and contrasted it with the activity of the same materials when the metal and the support were in direct physical contact.

“In three experiments, we were able to rule out different scenarios and prove that it is necessary to have physical contact between the palladium and titanium to produce methyl furan under these conditions,” Crossley said.

The carbon nanotube hydrogen highways can be used with a variety of different bifunctional catalysts.

“Using this straightforward and simple method, we can better understand how these complex materials work, and use this information to make better catalysts,” Crossley said.

Crossley and his OU team are working in collaboration with Jeff Miller, a chemical engineering professor at Purdue University. This work was supported by the National Science Foundation CAREER award 165393.

OU Radar Team Developing Mobile Radar Testbed for U.S. Navy

By Jana Smith, Director
Strategic Communications for R&D
University of Oklahoma


NORMAN—The University of Oklahoma Advanced Radar Research Center is developing an all-digital polarimetric phased array mobile radar testbed with a $5.4 million grant from the U.S. Department of Defense, Office of Naval Research, to address significant near-term obstacles and fulfill many operational missions. The ARRC team is providing a mobile radar testbed that can demonstrate multiple radar modes that increase public safety outcomes, such as weather monitoring and air traffic surveillance and control.

“The University of Oklahoma is the only university developing a system like this one,” said Mark Yeary, OU ARRC team leader and professor of electrical and computer engineering, OU Gallogly College of Engineering. “The ARRC has been successful in attracting the attention of the U.S. Navy and other agencies by building a team of experts that includes both meteorologists and engineers.”

Yeary and ARRC team members Robert Palmer, Caleb Fulton, Hjalti Sigmarrson, Jorge Salazar Cerrano and Nathan Goodman are working with Redmond Kelley, Matt McCord and John Meier, ARRC engineers on the project. The team is responsible for all aspects of the project, including electrical and mechanical design, mechanical assembly, thermal designs, data and processing control, a chiller system, truck with factory integrated generator, array positioner, enclosure and truck modifications.

“The all-digital radar can do what most radars cannot do, which is why the U.S. Navy is extremely interested in the capabilities of this mobile radar testbed. We are fully engaged in the research and development the U.S. Navy is doing and are addressing their needs with this project,” said Caleb Fulton, professor of electrical and computer engineering, Gallogly College of Engineering.

The funding from the U.S. Navy was made possible by foundational work on the so-called Horus all-digital polarimetric phased array radar done in collaboration with NOAA’s National Severe Storms Laboratory for the weather applications. The new system will build upon this work with NOAA and is defined by its flexibility and the software is easily reconfigured to address the challenges the U.S. Navy will face in the future.

This is the second grant the ARRC team has received from the ONR this year for developing new technologies that will advance the U.S. Navy’s mission. For more information, contact Yeary at yeary@ou.edu or visit the ARRC website at https://arrc.ou.edu.
















































OU Engineering Professor Receives DARPA Young Faculty Award

Andrea L'Afflitto and Michel Fiddy, DARPA Young Faculty Award Program Manager
Funding goes toward development of military drones

Andrea L’Afflitto, an assistant professor at the School of Aerospace and Mechanical Engineering at the University of Oklahoma, has received the Defense Advanced Research Projects Agency’s Young Faculty Award for his proposal to develop autonomous drones for tactical operations.

“We are at dawn of new technology as drones continue making great strides,” said L’Afflitto. “However, there’s still a lot more to explore with how this technology can be advantageous to our lives.”

The Defense Advanced Research Projects Agency award will fund the development of unmanned aerial systems such as drones. Existing technology, such as quadcopters or machines with robotic arms, move laterally. L’Afflitto’s research focuses on teaching drones to act in a tactical manner while mimicking human movements and thoughts, specifically among the armed forces. He proposed ground troops would use drones during warfare, transportation and reconstruction so that risk of detection is minimized. The goal is to utilize drones as a relatively cost-effective way to perform duties without sacrificing personnel.

Although the drone market is increasing rapidly, there are valid arguments regarding ethics. L’Afflitto said it’s important to evaluate regulations, including key factors such as height limits, designated restricted zones such as civilian areas and consistent oversight with surveillance.

“There’s definitely a moral responsibility related to interacting with drones,” said L’Afflitto. “Safety should always be a top priority. Effective countermeasures can help prevent accidents and liability.”

DARPA Young Faculty awards identify and engage rising stars in junior faculty positions in academia and researchers at nonprofit research institutions with the aim of addressing national security challenges and advancing fundamental research in diverse disciplines.

Engineers in Brazil: A Student's Perspective From Experience in Rio de Janeiro

Noelle Vargas - May 2018
By Noelle Vargas

“People change people: that is the secret of life.” – Mark Blutman

Who are we? What impact do we want to leave on our world? The definition of “our world”- what does that encompass? As an OU student, our eyes stretch from the residential towers down the South Oval to the engineering quad. However, there is more to our world than the twenty minute hike across campus. It is easy to claim that as a student “our world” is focused on improving ourselves academically and climbing organizational hierarchies. However, there is more to our world and there is more to what we can offer. Our brain for nine months in a calendar year, is focused on increasing knowledge to pursue a career in our desired field. But what world do we desire to impact through our career? Our world is bigger than OU’s campus - bigger than Norman - bigger than Oklahoma - and even bigger than the United States. This seems statistically obvious: a world is bigger than a country. However, how many times do we actually take a step back and consider the entirety of our world? We, especially myself, get too caught up in our own lives that we do not know about the lives experienced elsewhere.

Studying abroad provides the opportunity to widen our horizons and have another culture seep into our character. “Engineers in Brazil” is unlike any program. From the beginning of the program, our professors, Dean Mike Stice and Dr. Robert Huck ingrained in us, the students, that we were taking part in more than just the courses of Engineering Professional Development and Introduction to Petroleum Engineering; we were also actively incorporating culture into the classroom. We were opening our minds and hearts to the world and its reachable possibilities. Education is not a four-year journey - it is a lifetime of learning. We were encouraged to observe and analyze the similarities and differences between our United States culture and the Brazilian culture, rather than categorizing in our heads which is better. Before traveling to Rio de Janeiro, there were many precautionary statements about pickpocketing, diseases, infections bugs, and questionable safety. Rather, I found the areas we traveled to within the state of Rio de Janeiro – including Rio de Janeiro (City), Leblon, Ipanema, Copacabana, and neighboring cities – to be safe with locals who showed the utmost care and openness to help. English was definitely not a spoken language in the state of Rio de Janeiro, but the locals that we met, truly tried to help us when we were lost or confused tourists. There are many assumptions made about other places of our world. However, it is only when we become bold and take the risk to come face-to-face with the new place that we can make our own conclusions about a country and become global citizens.

Realizing we had the opportunity to engage with the local citizens excited me even before heading onto a plane for Brazil. We met Brazilian engineering students from the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) and high schoolers from the American School of Rio de Janeiro. They gave us their own insight on their Brazilian culture while sharing their respective aspirations in the engineering field. What I thoroughly enjoyed even more was how easy the flow of conversation was. We were all either in our twenties or late teens who had the same interests and passions as we shared the Millennial culture. They shared with us things to do, places to go, and food to eat in Rio de Janeiro while we told them vice versa the things to do in Oklahoma and the United States. Accompanied by the PUC-Rio engineering students, we traveled across the state to Halliburton, Baker Hughes a GE company, INMETRO, Enel, and many other engineering companies. There, we learned about the work of the professional engineers in their respective companies living in Brazil.
Traveling to a new continent, not speaking the language, and not knowing the other OU students and faculty members defines chaos for me. Honestly, I was scared about how I was going to connect with the 14 others on this study abroad adventure. However, it is at the very edge of chaos where one experiences the finest learning. We were 15 people who were on a new experience and territory, which led us to seek a “home” within each other. What amazed me was how we were able to trust each other enough to be raw. We were all living together for two weeks and every emotion was experienced. We saw each other in our hypest of times, groggiest of times, and all other emotions in between. This is what makes studying abroad so unifying - we trusted each other and felt secure enough to be open and show the deep layers of our character. I never thought I would grow to appreciate and become greatly fond of a group of people so quickly.

As students, this two week summer program taught us to embrace culture. It is important that we incorporate the positive aspects of another culture, the Brazilian culture, learned elsewhere into our own culture and lives in the United States. Through observing the Brazilian culture, I learned to always keep an open eye and hand to those surrounding me and recognize when they need help. I learned that the United States culture is not the only culture in our world and that we cannot think it is better than the rest. I learned that the competitive culture and thoughts of “How can I be the best, be on top, and beat everyone else?” is the wrong perception. Through studying abroad in Brazil, I was quick to learn that not everyone in our world thinks about their own personal progression in life, but instead looks around and seeks assisting others in the progression of their lives. One day, we will become professional engineers who will work with colleagues who could be from any of the continents in our world. In any engineering company, one will always recognize that engineering is a profession that has racial diversity. “Engineers in Brazil” taught us that world peace will be achieved through interpersonal relationships. It taught us that in order to leave an impact in anything we must become global citizens and combine leadership, culture, and positive change together. We left Rio de Janeiro with a broader insight to the world and the urge to meet more of it. We left with desire burning in us to impact our world, create those interpersonal relationships, and create world peace. We departed Brazil with the possibility of questioning the unquestionable. The best part is that as a student, you can see in the eyes of both professors the belief they had in us, the students and our generation. They believed in the capability of young, bright engineers who when posed with an issue will strive to fix it.

Ms. Regennia, first and foremost, thank you for sending me the scholarship opportunity information and encouraging me to apply.

Jabar Shumate – Vice President for University Community, OU
Mr. Jabar, thank you for writing a letter of recommendation to support my application. I really appreciated you not making me write it myself, and then you sign it like some people ask you to do. Your letter of recommendation let me and others know that you really knew me and my potential. My participation in the 2017 OU George McLaurin Male Leadership Conference helped me as an incoming freshman. I also benefited by volunteering with the 2018 Leadership Class. Those experiences really connected us.

Lisa Morales – Executive Director of the Diversity and Inclusion Program, Gallogly College of Engineering
Ms. Lisa, thank you and the entire Diversity & Inclusion team for making so many opportunities available for the D&I students. Those practice interviews, resume writing and group projects during the MEP Orientation and Freshman Engineering Experience classes were right on time! The STAR Interview and panel interview experiences gave me the confidence I needed. I had to go through two rounds of panel interviews using the STAR interview process with Toyota and Rainbow Push leadership over a two-day period.

Bushra Ashif, Global Engagement Fellowship and Fulbright Program Coordinator, OU College of International Studies
Professor Bushra, thank you for the Global Engagement experiences and scholarship. Fresh off my summer study abroad experience in Puebla, Mexico, prepared me to develop and present projects during the June Toyota two-day Interview Sell Event in Plano, Texas. I was able to step up and create the product idea. I led the group presentation with the elevator pitch during the group project that was a part of the judging process. I really slayed it! I'm sure my Global Engagement experiences listed on my resume set me apart from the other 22 finalists.

Crystal Garcia, Director of Diversity and Inclusion/MEP, OU Gallogly College of Engineering
Ms. Crystal, my freshman participation in the AT&T Summer Bridge Program provided me with the group experiences, technical references and situations to refer to during my STAR interviews.

I don't know what I would have done without your support during one of the most emotional times in my life.

Matthew Hamilton, Vice President of Enrollment and Student Financial Services
Mr. Matthew, you were so right! There were so many opportunities for me to figure out and plan to ensure that my college expenses were paid for without taking out student loans. Thank for always remembering me by name when I see you around campus.

As a computer engineering student in the Gallogly College of Engineering, I was definitely a standout among the other candidates representing colleges and universities from all over the United States. My design engineering, digital design, physics and programming classes gave me the technical experiences, vocabulary and confidence needed during the interviews and group project discussions.

Walking into Toyota North America Corporation’s awesome new high-tech building was not as overwhelming and intimidating as it may have been for some of the other candidates. I was at ease in the new state-of-the-art building and was familiar with the technical equipment because I have those experiences every day at OU! Lastly, meeting Toyota Boomer Sooners in high-level positions and on the interview panels made me feel right at home.

Once again, thank you OU family members for preparing me for this incredible journey. Every one of my OU freshman experiences with you positioned me for this phenomenal opportunity with Toyota North America Corporation. I can only imagine what the next three years at OU have in store for me. I'll keep you posted!

Boomer Sooner!
