Two teams from Georgia Tech have been awarded a combined $15 million from the U.S. Department of Defense (DoD) for basic research projects as part of the Multidisciplinary University Research Initiative (MURI) program. MURI seeks to fund research teams with creative and diverse solutions to complex problems and is a major part of the DoD’s research portfolio.

Alper Erturk (Lead PI), Carl Ring Family Chair and professor in the George W. Woodruff School of Mechanical Engineering, and Yuhang Hu, associate professor and Woodruff Faculty Fellow in the Woodruff School and the School of Chemical and Biomolecular Engineering, were awarded $7.5 million for their project, Bio‐Inspired Material Architectures for Deep Sea (BIMADS). Randall Engle, professor in the School of Psychology, was awarded the same amount for his project titled Understanding and Building Overall Cognitive Capability Through Attention Control.

Erturk and Hu’s interdisciplinary project will explore the fundamental science behind the biological characteristics that allow deep sea fish to adapt and survive in high pressure ocean environments. They will then translate those findings to engineer bioinspired materials needed to realize the Navy’s advanced capabilities in deep sea environments.

“In the deep ocean, marine organisms have evolved to thrive in high pressure environments, and adapt to pressure changes while remaining functional,” Erturk said. “Our goal for this project is to discover, test, and translate biological mechanisms into synthetic materials and structures that can dynamically adapt to high pressures in the ocean.”

Specifically, the researchers will test and explore the origins of the biological mechanisms (both molecular and macroscopic) that underlie the ability for deep sea snailfish to adapt to high pressures, pressure changes, and pressure differentials across material interfaces. Using findings from the biological studies, the researchers will design synthetic materials and structures that will then be evaluated in high pressure chambers.

“Knowledge gained from these studies will provide insight toward the design of structures spanning from atmospheric dive suits to robotic fish for the deep ocean,” Hu said.

BIMADS brings together experts in marine biology, bioengineering, biomimetic materials, chemistry, mechanochemistry and multiphysics chemomechanical modeling, hydrogel synthesis, biohybrid material fabrication, and the design, mechanics, and dynamics of architected structures. In addition to Erturk and Hu, the team also includes Anna Balazs and Lance Davidson from the University of Pittsburgh, John Costello from Providence College, Shashank Priya from the University of Minnesota, and Andrew Sarles from the University of Tennessee.

Attention Control in Naval Training

Engle’s project will explore the brain’s mechanisms of attention control and investigate methods to potentially improve it or reduce its decline.

“We want to better understand the role that controlling attention and individual differences in that ability has in real-world, complex tasks such as flying a plane, driving a car, or even studying for a physics test,” Engle said. “We expect this work will help the Navy identify job trainees who are best able to attend to complex tasks, and also help to mitigate the effects of fatigue and mind wandering common to those tasks.”

According to Engle, the Navy trains about a thousand air traffic control professionals each year and spends over $100,000 per candidate. But nearly a quarter of candidates fail training, leading to significant financial waste.

Engle’s work with air traffic control trainees showed that current evaluations used to select candidates for training only predicts a small percentage of success. Engle found that, by using his measures of ability to control attention in evaluations, the Navy could more than double predictive success in candidate training. In addition, researchers found that Engle’s measures appeared to have less adverse impact and bias against women and minority candidates.

Engle’s collaborative research team includes researchers from MIT, the University of Chicago, Purdue University, and Michigan State University. Each team member is studying a different aspect of attention control.

Idling at a crossroads no longer, the automotive industry is embracing electrification like never before. With more electric vehicles purchased in 2022 than any year prior, consumers are beginning to follow their lead. Yet, while opportunity abounds, new challenges will require an innovative approach to ensure a sustainable and accessible electric future for all.

With historic investments from major players in the EV space, including Rivian, Kia, and Hyundai, the state of Georgia is uniquely positioned to serve as a leader in this effort. As the state's leading research institute, Georgia Tech is on the cutting edge of the movement. 

The transportation sector is the largest greenhouse gas emitter in the U.S. at nearly 30%, with passenger vehicles accounting for around 80% of the sector's total output1 as of 2019. Electric vehicles are widely regarded as a budding solution to reduce emissions, but even as both demand and production continue to increase, EVs currently account for around 1% of the cars on America's roadways. 

From the supply chain to the infrastructure needed to support alternative-fuel vehicles alongside consumer hesitancy, achieving the goals set by both the public and private sectors — including the Biden Administration's target of EVs making up at least 50% of new car sales by 2030 — will not be easy. Through research and development, policy, and collaboration, Tech experts are working toward finding solutions that will serve as catalysts during this transitionary period for the environment and the way Americans drive.

More than 1,500 parents and children across the Atlanta metropolitan area attended a jam-packed second annual Georgia Tech Science and Engineering Day held on Saturday, March 11 in conjunction with the tenth annual 2023 Atlanta Science Festival. Located across five campus buildings, more than 40 demonstrations, hands-on STEAM activities, tours, and learning opportunities designed to engage and educate participants were offered by students, staff, and faculty volunteers.

Some of this year’s demonstration topics included battery fuel cells, nanotechnology, DNA, immunoengineering, chemistry, engineering, superconductivity levitation, wastewater treatment, aerospace, space outreach, virtual reality, biology, robotics, computing, 3D printing, paper making, and much more.

A parent attending from Peachtree City said, “we’ve discovered our son has an affinity for math and science. He’s handling tenth grade science level coursework, yet he’s only in the seventh grade and can understand math formulas ahead of his age group. We brought him here to expose him to a variety of technologies and advanced equipment that he won’t see or be exposed to in his middle school. The staff and professors here have been very kind to show him how to use some of the equipment we’ve seen. And his eyes have gotten bigger all day because of these interactions.”

Virginia Howell, director of the Roberts C. Williams Museum of Paper Making in the Renewable Bioproducts Institute at Georgia Tech said, “the paper museum is delighted to be part of the Georgia Tech Science and Engineering Day. It's a great opportunity for people to learn more about the paper museum and get hands-on experience in making a sheet of paper to take home. We offer workshops, classes, and tours to students across the state of Georgia. Kids have been lined up all day to participate at our tables today.”

Demonstrations included how to extract DNA, seeing LIDAR in action, experiencing heat sensing sensors, how x-rays are used, viewing scanning electron microscopes, playing a virtual reality game, experiencing chemical reactions, watching 3D printing, making slime, showing atom-level nano materials in synthesized materials, neuroscience demos, liquid nitrogen experiments, and many more.

Presentation areas were hosted by the Institute for Electronics and Nanotechnology, the Institute for Robotics and Intelligent Machines, and the Institute for Bioengineering and Biosciences who provided valuable space in their buildings to house demonstrations. The Ford Environmental Science & Technology Building and Molecular Science & Engineering Building also donated space for demonstrations.

Another tour offering during Science and Engineering Day was the Flowers Invention Studio at Georgia Tech which offers more than 5,000 square feet of industrial makerspace equipment.

“We are the largest student-run maker space in the nation,” said Lillian Tso, president of the Invention Studio and a fourth-year mechanical engineering student. “We house industrial grade equipment for prototyping and manufacturing—we support anything that students want to build. We're open for all students of all majors of all years. They can use our equipment for free which includes CNC machines, more than 50 3D printers, waterjets, laser cutters, and many other professional-level tools. This is our first year participating in the Georgia Tech Science and Engineering Day. We wanted to do a lot more outreach to the Georgia Tech campus and the greater Atlanta community."

Lucas Garza, president-elect of the Invention Studio, added, “we’ve had a busy day offering tours of our studio throughout the festival.”

Located in the mezzanine of the Marcus Nanotechnology Building, Ethan Sirak, a fourth-year aerospace student with the Georgia Space Grant Consortium, was providing kids with exposure to space facts and allowing them to perform crafts related to planets and space. The consortium is an organization under NASA which aims to promote STEM exposure to kids of all ages. He also assists with the Aerospace Engineering Outreach Program. He was partnered at his hands-on learning table with Bill McNutt Jr., a senior aerospace engineering student.

A young participant from Suwanee, Georgia, said, “I want to go to school at Georgia Tech because of aerospace engineering. I want to go on good adventures in future space flight and design things.”

His mom, a sixth-grade science teacher added, “I love coming to science fairs to get new ideas for my students and I love to bring my family because we just have a great time. This is our very first science fair here at Georgia Tech. We've been to ones in north Georgia because that's pretty close to where we live. But when we saw this was available, we're like, yeah, we're coming down to Tech for this today—and having a great time.”

While attendees were able to get a peek into one of the nation’s most research-intensive universities, the event also allowed the many researchers and students participating the opportunity to share their science and engineering work with the public.

One of the more unique tables was manned by Alison Reynolds, an instruction archivist with research services in the Georgia Tech library. She was displaying a selection of unique items from Georgia Tech’s science fiction archives and special collections. She said, “we’ve been teaching with science fiction since 1971 and our collection is now one of the largest science fiction collections in the United States. We wanted to display part of our special collection.”

“I had several Georgia school systems reach out to me that were interested in attending this event,“ said Leslie O 'Neill, education outreach manager with the Southeastern Nanotechnology Infrastructure Corridor (SENIC) at Georgia Tech. “Georgia Tech plays a vital part in its community. We wanted to showcase the campus; the student, faculty and staff research; and the amazing science and engineering being done. We’ve had a fantastic turnout this year for this event.”
