From airplanes to soda cans, aluminum is a crucial — not to mention, an incredibly sustainable — material in manufacturing. Since 2019, Georgia Tech has partnered with Novelis, a global leader in aluminum rolling and recycling, through the Novelis Innovation Hub to advance research and business opportunities in aluminum manufacturing.

Novelis and the Georgia Institute of Technology recently co-hosted the 19th International Conference on Aluminum Alloys (ICAA19). Held on Georgia Tech's campus, this event brought together the brightest minds in aluminum technology for four days of intensive learning and networking.

Since its inception in 1986, ICAA has been the premier global forum for aluminum manufacturing innovations. This year, the conference attracted over 300 participants from 19 countries, including representatives from academia, research organizations, and industry leaders.

“The diverse mix of attendees created a rich tapestry of knowledge and experience, fostering a robust exchange of ideas,” said Naresh Thadhani, conference co-chair and professor in the School of Materials Science and Engineering

ICAA19 featured 12 symposia topics and over 250 technical presentations, delving into critical themes such as sustainability, future mobility, and next-generation manufacturing. Keynote addresses from leaders at the Aluminum Association, Airbus, and Coca-Cola set the stage for insightful discussions. Novelis Chief Technology Officer Philippe Meyer and Georgia Tech Executive Vice President for Research Chaouki Abdallah headlined the event, underscoring the importance of Novelis’ partnership with Georgia Tech.

Marking the fifth anniversary of the Novelis Innovation Hub at Georgia Tech, Hub Executive Director Shreyes Melkote says that “ICAA19 represents a prime example of the close collaboration between Novelis and the Institute, enabled by the Novelis Innovation Hub.” Melkote, a professor in the George W. Woodruff School of Mechanical Engineering, also serves as the associate director of the Georgia Tech Manufacturing Institute.

“This unique center for research, development, and technology has been instrumental in advancing aluminum innovations, exemplifying the power of partnerships in driving industry progress,” says Meyer. “As we reflect on the success of ICAA19, we remain committed to strengthening our existing partnerships and forging new alliances to accelerate innovation. The collaborative spirit showcased at the conference is a testament to our dedication to leading the aluminum industry into a more sustainable future.”

Semiconductors make our world run, but the industry faces a turning point. For decades, computer chip efficiency has doubled every two years, but that progress is slowing. To complicate the problem further, global demand for semiconductors threatens to outpace the supply. The U.S. has the opportunity to meet the growing need for chips — both by increasing domestic manufacturing and building up the workforce, which is at its lowest in decades. To bolster semiconductor research and manufacturing, in 2022, Congress passed the $52.7 billion bipartisan CHIPS and Science Act that President Joe Biden signed into law. New paradigms and pioneers are needed to make these critical advances.

Georgia Tech is playing a significant role in creating the next generation of chips, as the Institute is especially well positioned to innovate in the semiconductor field. All areas of the semiconductor stack — the components that build a chip, from hardware to artificial intelligence — are studied at Tech, and collaboration among faculty is a hallmark of its research enterprise. Such cooperation is necessary to build better chips, since they need to be reinvented in every layer of the stack.

Georgia Tech has been selected as one of six universities globally to receive funding for the newly established Global Industrial Technology Cooperation Center. The announcement was made by the Ministry of Trade, Industry, and Energy in South Korea during the Global Open Innovation Strategy Meeting in April.

The KIAT-Georgia Tech Semiconductor Electronics Center will receive $1.8 million to establish a sustainable semiconductor electronics research partnership between Korean companies, researchers, and Georgia Tech. 

“I am thrilled to announce that we have secured funding to launch a groundbreaking collaboration between Georgia Tech’s world-class researchers and Korean companies,” said Hong Yeo, associate professor and Woodruff Faculty Fellow in the George W. Woodruff School of Mechanical Engineering and the Wallace H. Coulter Department of Biomedical Engineering. “This initiative will drive the development of cutting-edge technologies to advance semiconductor, sensors, and electronics research.”

Yeo will lead the center, and Michael Filler, interim executive director for the Institute of Electronics and Nanotechnology, and Muhannad Bakir, director of the 3D Advanced Packaging Research Center, will serve as co-PIs.

The center will focus on advancing semiconductor research, a critical area of technology that forms the backbone of modern electronics.

The Cooperation Center is a global technology collaboration platform designed to facilitate international joint research and development planning, partner matching, and local support for domestic researchers. The selection of Georgia Tech underscores the Institute’s leadership and expertise in the field of semiconductors.

Quantum sensors detect the smallest of environmental changes — for example, an atom reacting to a magnetic field. As these sensors “read” the unique behaviors of subatomic particles, they also dramatically improve scientists’ ability to measure and detect changes in our wider environment.

Monitoring these tiny changes results in a wide range of applications — from improving navigation and natural disaster forecasting, to smarter medical imaging and detection of biomarkers of disease, gravitational wave detection, and even better quantum communication for secure data sharing.

Georgia Tech physicists are pioneering new quantum sensing platforms to aid in these efforts. The research team’s latest study, “Sensing Spin Wave Excitations by Spin Defects in Few-Layer Thick Hexagonal Boron Nitride” was published in Science Advances this week. 

The research team includes School of Physics Assistant Professors Chunhui (Rita) Du and Hailong Wang (corresponding authors) alongside fellow Georgia Tech researchers Jingcheng Zhou, Mengqi Huang, Faris Al-matouq, Jiu Chang, Dziga Djugba, and Professor Zhigang Jiang and their collaborators. 

An ultra-sensitive platform

The new research investigates quantum sensing by leveraging color centers — small defects within crystals (Du’s team uses diamonds and other 2D layered materials) that allow light to be absorbed and emitted, which also give the crystal unique electronic properties. 

By embedding these color centers into a material called hexagonal boron nitride (hBN), the team hoped to create an extremely sensitive quantum sensor — a new resource for developing next-generation, transformative sensing devices. 

For its part, hBN is particularly attractive for quantum sensing and computing because it could contain defects that can be manipulated with light — also known as "optically active spin qubits."

The quantum spin defects in hBN are also very magnetically sensitive, and allow scientists to “see” or “sense” in more detail than other conventional techniques. In addition, the sheet-like structure of hBN is compatible with ultra-sensitive tools like nanodevices, making it a particularly intriguing resource for investigation.

The team’s research has resulted in a critical breakthrough in sensing spin waves, Du says, explaining that “in this study, we were able to detect spin excitations that were simply unattainable in previous studies.” 

Detecting spin waves is a fundamental component of quantum sensing, because these phenomena can travel for long distances, making them an ideal candidate for energy-efficient information control, communication, and processing.

The future of quantum

“For the first time, we experimentally demonstrated two-dimensional van der Waals quantum sensing — using few-layer thick hBN in a real-world environment,” Du explains, underscoring the potential the material holds for precise quantum sensing. “Further research could make it possible to sense electromagnetic features at the atomic scale using color centers in thin layers of hBN.”

Du also emphasizes the collaborative nature of the research, highlighting the diverse skill sets and resources of researchers within Georgia Tech. 

“Within the School of Physics, Professor Zhigang Jiang's research group provided the team with high-quality hBN crystals. Jingcheng Zhou, who is a member of both Professor Hailong Wang’s and my research teams, performed the cutting-edge quantum sensing measurements,” she says. “Many incredible students also helped with this project.”

Du is a leading scientist in the field of quantum sensing — this year, she received a new grant from the U.S. Department of Energy, along with a Sloan Research Fellowship for her pioneering work on developing state-of-the-art quantum sensing techniques for quantum information technology applications. The prestigious Sloan award recognizes researchers whose “creativity, innovation, and research accomplishments make them stand out as the next-generation of leaders in the fields.”

Effective July 1, Eric Vogel will become the executive director of the Institute for Matter and Systems (IMS), Georgia Tech’s newest Interdisciplinary Research Institute (IRI) that will launch on the same date.

As an evolution of the Institute for Materials (IMat) and the Institute for Electronics and Nanotechnology (IEN), IMS aims to enable convergent research at Georgia Tech related to the science, technology, and societal underpinnings of innovative materials and devices. Additionally, IMS seeks to integrate these innovations into systems that enhance human well-being and performance across information and communication, the built environment, and human-centric technologies that improve human health, wellness, and performance.

“Executive Vice President for Research Chaouki Abdallah and I are very excited about the launch of IMS, which positions Georgia Tech for integration of science and technology from atoms to devices, while explicitly drawing in researchers in the social sciences, design, business, and computing,” said Vice President of Interdisciplinary Research Julia Kubanek.

“IMS will ensure relevance across Georgia Tech through its newly configured Internal Advisor and Ambassador Board with representation across all six Colleges and GTRI,” she said. “Additional advisory committees representing IMS employees and facility users will ensure that we don’t sacrifice any of the research excellence for which IEN and IMat are known. With IMS I expect we will be even better positioned to tackle research problems that will have the greatest positive societal impact.”

Vogel will continue in his current position as the executive director of IMat until the launch of IMS. In addition to leading and growing IMat, Vogel is the Hightower Professor of Materials Science and Engineering at Georgia Tech’s School of Materials Science and Engineering, and he served as the IEN deputy director prior to leading IMat.

“It is an honor to be appointed executive director of the Institute for Matter and Systems, and I look forward to collaborating with the talented faculty and staff associated with it,” said Vogel. “This opportunity allows us to leverage the core competencies of IEN and IMat while extending our capabilities beyond nanotechnology and materials science. Together, we will be a hub for interdisciplinary research ranging from advanced materials to complex systems that solve global challenges.”

Georgia Tech’s IRIs facilitate collaboration between researchers and students from its six Colleges, the Georgia Tech Research Institute, national laboratories, and corporate entities to tackle critical topics of strategic significance for the Institute as well as for local, state, national, and international communities. IMS will also house and maintain the state-of-the-art Materials Characterization Facility and one of the largest academic cleanrooms in the nation, which offers a broad range of fabrication capabilities from basic discovery to prototype realization.

Before joining Georgia Tech in 2011, Vogel was an associate professor of materials science and engineering and electrical engineering at the University of Texas at Dallas. During this time, he also served as the associate director of the Texas Analog Center of Excellence and led UT Dallas’s involvement in the Southwest Academy for Nanoelectronics.

Prior to UT Dallas, he led the CMOS and Novel Devices Group and established the Nanofabrication Facility at the National Institute of Standards and Technology. Vogel holds a Ph.D. in electrical engineering from North Carolina State University and a B.S. in electrical engineering from the Pennsylvania State University. His research focuses on the development and fundamental understanding of electronic and nanomaterials and devices.

More than 400 people participated in Energy Materials Day on March 27, as researchers and industry leaders came together to discuss and advance energy materials technologies such as solar energy, carbon-neutral fuels, and batteries.

Energy materials are the things — natural, manufactured, or both — that aid the use of energy. They also play a key role in developing cleaner, more efficient energy solutions.

Energy Materials Day was co-hosted by Georgia Tech’s Strategic Energy Institute (SEI), the Institute for Materials (IMat), and the Georgia Tech Advanced Battery Center. The event evolved out of last year’s Georgia Tech Battery Day.

“As an engine of innovation in science and technology, Georgia Tech has incredible opportunities and the responsibility to conduct research to benefit society,” said Chaouki Abdallah, executive vice president for Research at Georgia Tech. “We call this ‘research that matters.’”

Events like Energy Materials Day are part of an ongoing, long-range effort to position Georgia Tech, and Georgia, as a go-to location for modern energy companies. Tech was recently ranked by U.S. News & World Report as the top public university for energy research. Abdallah also outlined why Georgia Tech, with more than 1,000 researchers across campus working in the energy space, is a natural fit for events that foster collaboration between the public and private sectors.

“Right here, right now, we have the opportunity to harness our collective powers, our collective knowledge, our collective resources to become a global engine of innovation,” he said.

Plenary speaker Danielle Merfeld, global chief technology officer at QCells, highlighted opportunities for the current and future clean energy infrastructure in the United States.

"At the heart of our discussions today [are these questions]: What is new technology, and how do you make it ... and make it at scale, in an affordable, accessible, and reliable way?” she said.

"... [The] good news is this country has taken a very deliberate step toward creating the most robust industrial policy we've had in decades. ... This is driving opportunity and creating the foundation for manufacturing. So, [we can] use that industrial base of making and consuming power [and] decarbonize the electric grid by 2035...."

“Events like this are so important to forwarding progress in research and industry,” said Eric Vogel, IMat’s executive director. “It’s important to bring together professionals throughout the industry to keep these lines of communication open.”

The day was divided into three tracks: battery materials and technologies, photovoltaics and the grid, and materials for carbon-neutral fuel production. Attendees were encouraged to listen to talks from all three areas. Each track included academic speakers who shared their research and private-sector speakers who described how technological advancements are affecting the industry.

“With its rich history in energy research, Georgia Tech remains a leader in addressing global energy challenges,” said Tim Lieuwen, executive director of SEI. “The success of Energy Materials Day is encouraging, and I eagerly anticipate continuing these discussions in 2025.”

Jud Ready, a principal research engineer at the Georgia Tech Research Institute (GTRI), has been selected to join the National Academy of Inventors’ (NAI) 2024 Class of Senior Members – a group of 124 academic inventors from NAI’s Member Institutions who have made significant contributions to innovation and technology.

Holding a dual appointment as Deputy Director of Innovation Initiatives for Georgia Tech’s Institute for Materials, one of Tech’s 10 Interdisciplinary Research Institutes (IRI) focused on advancing materials research and innovation, and with over two decades of experience as an adjunct professor in Tech’s School of Materials Science & Engineering, Ready has established himself as a leader in materials science and engineering.

Matthew McDowell, Woodruff Faculty Fellow and associate professor in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering and initiative lead for energy storage at the Strategic Energy Institute, has received $1.3 million in funding through the Pioneering Railroad, Oceanic, and Plane Electrification with 1K energy storage systems (PROPEL-1K) program. Aimed at accelerating the electrification of the aviation, railroad, and maritime transportation sectors, PROPEL-1K is one of the latest ARPA-E grants with projects to develop energy storage systems that can achieve over 1,000 watt-hour per kilogram and 1,000 watt-hour per liter. These technologies will improve energy density fourfold over current technologies.

Inspired by fuel injectors in internal combustion engines and conventional flow batteries, McDowell’s project will advance an alkali hydroxide triple phase flow battery to enable reversible operation of ultrahigh-energy density battery chemistries. The project’s proposed design will increase energy density by leveraging innovative pumping and handling of molten alkali metal and hydroxide species to maximize the volume of reactants over inactive components.

McDowell will work with Asegun Henry, associate professor in the Department of Mechanical Engineering at the Massachusetts Institute of Technology (MIT). Prior to MIT, Henry was an assistant professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech.

Created in 2007, the Advanced Research Projects Agency-Energy (ARPA-E) in the Department of Energy advances high-potential, high-impact energy technologies. The agency focuses on transformational energy projects that can be meaningfully advanced with a small amount of funding over a defined period through a streamlined awards process that enables quick action and catalyzes cutting-edge areas of energy research.

Energy is everywhere, affecting everything, all the time. And it can be manipulated and converted into the kind of energy that we depend on as a civilization. But transforming this ambient energy (the result of gyrating atoms and molecules) into something we can plug into and use when we need it requires specific materials.

These energy materials — some natural, some manufactured, some a combination — facilitate the conversion or transmission of energy. They also play an essential role in how we store energy, how we reduce power consumption, and how we develop cleaner, efficient energy solutions.

“Advanced materials and clean energy technologies are tightly connected, and at Georgia Tech we’ve been making major investments in people and facilities in batteries, solar energy, and hydrogen, for several decades,” said Tim Lieuwen, the David S. Lewis Jr. Chair and professor of aerospace engineering, and executive director of Georgia Tech’s Strategic Energy Institute (SEI).

That research synergy is the underpinning of Georgia Tech Energy Materials Day (March 27), a gathering of people from academia, government, and industry, co-hosted by SEI, the Institute for Materials (IMat), and the Georgia Tech Advanced Battery Center. This event aims to build on the momentum created by Georgia Tech Battery Day, held in March 2023, which drew more than 230 energy researchers and industry representatives.

“We thought it would be a good idea to expand on the Battery Day idea and showcase a wide range of research and expertise in other areas, such as solar energy and clean fuels, in addition to what we’re doing in batteries and energy storage,” said Matt McDowell, associate professor in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering (MSE), and co-director, with Gleb Yushin, of the Advanced Battery Center.

Energy Materials Day will bring together experts from academia, government, and industry to discuss and accelerate research in three key areas: battery materials and technologies, photovoltaics and the grid, and materials for carbon-neutral fuel production, “all of which are crucial for driving the clean energy transition,” noted Eric Vogel, executive director of IMat and the Hightower Professor of Materials Science and Engineering.

“Georgia Tech is leading the charge in research in these three areas,” he said. “And we’re excited to unite so many experts to spark the important discussions that will help us advance our nation’s path to net-zero emissions.”

Building an Energy Hub

Energy Materials Day is part of an ongoing, long-range effort to position Georgia Tech, and Georgia, as a go-to location for modern energy companies. So far, the message seems to be landing. Georgia has had more than $28 billion invested or announced in electric vehicle-related projects since 2020. And Georgia Tech was recently ranked by U.S. News & World Report as the top public university for energy research.

Georgia has become a major player in solar energy, also, with the announcement last year of a $2.5 billion plant being developed by Korean solar company Hanwha Qcells, taking advantage of President Biden’s climate policies. Qcells’ global chief technology officer, Danielle Merfeld, a member of SEI’s External Advisory Board, will be the keynote speaker for Energy Materials Day.

“Growing these industry relationships, building trust through collaborations with industry — these have been strong motivations in our efforts to create a hub here in Atlanta,” said Yushin, professor in MSE and co-founder of Sila Nanotechnologies, a battery materials startup valued at more than $3 billion.

McDowell and Yushin are leading the battery initiative for Energy Materials Day and they’ll be among 12 experts making presentations on battery materials and technologies, including six from Georgia Tech and four from industry. In addition to the formal sessions and presentations, there will also be an opportunity for networking.

“I think Georgia Tech has a responsibility to help grow a manufacturing ecosystem,” McDowell said. “We have the research and educational experience and expertise that companies need, and we’re working to coordinate our efforts with industry.”

Marta Hatzell, associate professor of mechanical engineering and chemical and biomolecular engineering, is leading the carbon-neutral fuel production portion of the event, while Juan-Pablo Correa-Baena, assistant professor in MSE, is leading the photovoltaics initiative.

They’ll be joined by a host of experts from Georgia Tech and institutes across the country, “some of the top thought leaders in their fields,” said Correa-Baena, whose lab has spent years optimizing a semiconductor material for solar energy conversion.

“Over the past decade, we have been working to achieve high efficiencies in solar panels based on a new, low-cost material called halide perovskites,” he said. His lab recently discovered how to prevent the chemical interactions that can degrade it. “It’s kind of a miracle material, and we want to increase its lifespan, make it more robust and commercially relevant.”

While Correa-Baena is working to revolutionize solar energy, Hatzell’s lab is designing materials to clean up the manufacturing of clean fuels.

“We’re interested in decarbonizing the industrial sector, through the production of carbon-neutral fuels,” said Hatzell, whose lab is designing new materials to make clean ammonia and hydrogen, both of which have the potential to play a major role in a carbon-free fuel system, without using fossil fuels as the feedstock. “We’re also working on a collaborative project focusing on assessing the economics of clean ammonia on a larger, global scale.”

The hope for Energy Materials Day is that other collaborations will be fostered as industry’s needs and the research enterprise collide in one place — Georgia Tech’s Exhibition Hall — over one day. The event is part of what Yushin called “the snowball effect.”

“You attract a new company to the region, and then another,” he said. “If we want to boost domestic production and supply chains, we must roll like a snowball gathering momentum. Education is a significant part of that effect. To build this new technology and new facilities for a new industry, you need trained, talented engineers. And we’ve got plenty of those. Georgia Tech can become the single point of contact, helping companies solve the technical challenges in a new age of clean energy.”

Georgia Institute of Technology School of Electrical and Computer Engineering Ph.D. candidate Fabia Farlin Athena received the prestigious Stanford Energy Postdoctoral Fellowship, becoming Georgia Tech’s first recipient of the distinction.

With climate change becoming one of the a defining issue of the 21st century, the transition to a low-carbon energy system will solve about three-fourths of the problem, according to the fellowship’s website. At the same time, the new energy system needs to be affordable, reliable, and available to the average person.

The three-year fellowship sponsored in Stanford’s Precourt Institute of Energy and Doerr School of Sustainability aims to identify, develop, and connect the next generation of energy leaders — from science and engineering to policy and economics — to translate theoretical climate change solutions into tangible realities.

At Stanford, Athena, who is advised by Eric M. Vogel in the School of Materials Science and Engineering, will work on emerging materials and devices for energy-efficient sustainable computing. She will be working with H.-S. Philip Wong, professor of electrical engineering, and Alberto Salleo, professor of materials science and engineering.

After being selected as a finalist, she presented her current Ph.D. research on adaptive oxide devices for energy-efficient computing, as well as her proposed research to the fellowship’s advisory board.

“It was an amazing experience to go through the selection process of writing the proposal and finally getting interviewed by the honorable advisory board,” Athena said. “It was humbling to get the opportunity to discuss my research with a person I have always looked up to in Professor Steven Chu, a Nobel Laureate in Physics and former U.S. Secretary of Energy!”

Athena is just one of 10 fellows selected globally this year. The fellowship provides her the opportunity to explore new and profound postdoctoral research that is distinct from her Ph.D. work.

“I am deeply grateful to my advisor Prof. Eric M. Vogel for his constant kind support throughout my Ph.D. and for believing in me,” Athena said. “He has been a pillar of constant support throughout my journey. I am also grateful to Prof. Samuel Graham for his kind constant support, including for this fellowship. I am thankful to my respected P.I.s at Stanford, Professor H.-S. Philip Wong, and Professor Alberto Salleo for their support of my proposal. I am also grateful to my respected mentors Prof. Suman Datta, Prof. William Alan Doolittle, Dr. Takashi Ando, and Dr. Vijay Narayanan for their kind support, advice, and opportunities. Finally, I would like to thank Georgia Tech ECE for providing the platform for learning, exploration, and collaboration.”

Before her time at Georgia Tech, Athena received her undergraduate degree in materials science and engineering from the Bangladesh University of Engineering and Technology. She then spent two semesters at Purdue University as a graduate researcher, where she collaborated with the Idaho National Lab on nuclear materials for next-generation energy.

Athena’s research has been recognized with the Georgia Tech ECE Ph.D. Fellowship, 2022 Cadence Diversity in Technology Scholarship, 2023 EECS Rising Stars, 2023 Colonel Oscar P. Cleaver Award for the most outstanding Ph.D. dissertation proposal in Georgia Tech ECE, 2023 MRS Graduate Student Award, and IBM Ph.D. Fellowship from 2022-2024.
