Urmanbetova Jamboree

One of the Institute Strategic Plan (ISP) goals is to connect globally and amplify impact by contributing “to global collaborative efforts that advance the U.N. Sustainable Development Goals (SDGs) through our education, research, and service.” In response, Sustainability Next developed a plan to expand SDG concept and skill integration across the undergraduate curriculum. In support of the plan, 21 projects representing all six colleges and 15 schools were presented at the Undergraduate Sustainability Education Jamboree, held on April 26 in the Kendeda Building auditorium. With many winning projects featuring high enrollment and core courses, this first round of sustainability education “seed grants” will significantly expand the reach of Georgia Tech’s sustainability-across-the-curriculum initiatives.

“Our Strategic Plan commitment to bring the United Nations Sustainable Development Goals (SDGs) into our teaching is part of our vision for transformative teaching and learning more broadly,” explains Larry Jacobs, Senior Vice Provost for Education and Learning. “Helping students identify connections between disciplinary concepts and skills and complex societal challenges enhances learning and supports Georgia Tech’s mission to equip students to improve the human condition.”

The Jamboree featured lightning presentations from the award winners, as well as presentations about related initiatives at Georgia Tech to help instructors, students, and staff better understand the landscape of sustainability education innovation on campus. Instructors engaged in course design or re-design through the awards will have opportunities to collaborate with and learn from their peers through a Community of Practice on Transformative Teaching with the SDGs and a SoTL (Scholarship of Teaching and Learning) research group. Many began identifying potential collaborators at the event, as they heard from other award winners. “The afternoon of lightning presentations by fellow faculty was exhilarating,” Sabir Khan, Associate Professor, Schools of Industrial Design and Architecture, shared. “I came away impressed and excited at the range of projects and have already invited a few instructors to join my class in the fall to discuss their approaches to tackling the UN SDGs."

Presenter Kate Williams, Interim Director, Transformative Teaching and Learning, Faculty Initiatives, shared connections between the Sustainability Innovation Awards and Georgia Tech’s Transformative Teaching and Learning (TTL) strategic initiative. “The success of the first round of Sustainability Education Innovation Grants demonstrates our faculty's commitment to creating innovative experiential learning opportunities for students,” Dr. Williams noted.

On April 26, 2023, the School of Physics and College of Sciences at Georgia Tech will welcome Stanford University physicist Steven Chu to speak on climate change and innovative paths towards a more sustainable future. Chu is the 1997 co-recipient of the Nobel Prize in Physics, and in his former role as U.S. Secretary of Energy, became the first scientist to hold a U.S. Cabinet position.

About the Talk

The event is part of the School of Physics “Inquiring Minds” public lecture series, and will be held at the Ferst Center for the Arts. The talk is free and open to campus and the Atlanta community, and no RSVP is required. Refreshments begin at 4:30, and the lecture will start at 5 p.m. ET.

“The multiple industrial and agricultural revolutions have transformed the world,” Chu recently shared in an abstract for the lecture. “However, an unintended consequence of this progress is that we are changing the climate of our planet. In addition to the climate risks, we will need to provide enough clean energy, water, and food for a more prosperous world that may grow to 11 billion by 2100.” 

The talk will discuss the significant technical challenges and potential solutions that could provide better paths to a more sustainable future. “How we transition from where we are now to where we need to be within 50 years is arguably the most pressing set of issues that science, innovation, and public policy have to address,” Chu added. 

The event’s faculty host is Daniel Goldman, Dunn Family Professor in the School of Physics at Georgia Tech.

About Steven Chu

Steven Chu is the William R. Kenan, Jr. Professor of Physics and a professor of Molecular and Cellular Physiology in the Medical School at Stanford University.

Chu served as the 12th U.S. Secretary of Energy from January 2009 until the end of April 2013. As the first scientist to hold a U.S. Cabinet position and the longest serving Energy Secretary, Chu led several initiatives including ARPA-E (Advanced Research Projects Agency – Energy), the Energy Innovation Hubs, and was personally tasked by President Obama to assist in the Deepwater Horizon oil leak.

In the spring of 2010, Chu was the keynote speaker for the Georgia Tech Ph.D. and Master's Commencement Ceremony.

Prior to his cabinet post, Chu was director of the Lawrence Berkeley National Laboratory, where he was active in pursuit of alternative and renewable energy technologies, and a professor of Physics and Applied Physics at Stanford, where he helped launch Bio-X, a multi-disciplinary institute combining the physical and biological sciences with medicine and engineering. Previously he also served as head of the Quantum Electronics Research Department at AT&T Bell Laboratories.

He is the co-recipient of the 1997 Nobel Prize in Physics for his contributions to laser cooling and atom trapping. He is a member of the National Academy of Sciences, the American Philosophical Society, the American Academy of Arts and Sciences, the Pontifical Academy Sciences, and of seven foreign academies. He formerly served as president, and then chair of the American Association for the Advancement of Science.

Chu earned an A.B. degree in mathematics and a B.S. degree in physics from the University of Rochester, and a Ph.D. in physics from the University of California, Berkeley, as well as 35 honorary degrees.

He has published over 280 papers in atomic and polymer physics, biophysics, biology, bio-imaging, batteries, and other energy technologies. He holds 15 patents, and an additional 15 patent disclosures or filings since 2015.

The Community Garden prior to its expansion.

As Georgia Tech continues to celebrate Earth Month, Friday's ribbon-cutting ceremony for the newly expanded Community Garden represents another step in the Institute's commitment to a sustainable future.

First opened in 2012 with six small planting beds, the garden has received a complete transformation over the past decade. With the latest project, which began in July 2022, essentially doubling its square footage, the garden now touts 21 fruit trees and nine large beds that are free and open to students. Two additional medium and nine small beds are available for lease for the Tech community. A new shed for gardening tools has been constructed alongside a brand-new demo kitchen to feature the garden's produce in healthy recipes. With the inclusion of slate-chip pathways and high-density mulch, the garden is now fully ADA accessible — a primary goal of the expansion effort.

Elias Winterscheidt was drawn to the garden while touring the Tech campus in 2019. With prior planting experience, he immediately got involved with Students Organizing for Sustainability (SOS), taking over as the Community Garden director in April 2021. Over the past three semesters before construction began, the garden donated 50 pounds of produce to Klemis Kitchen — Georgia Tech's on-campus food bank — in addition to the produce harvested by 500 volunteers during that time.

Winterscheidt anticipates the growth of the garden community continuing, with hopes of doubling both donations to Klemis Kitchen and the number of volunteers.

SOS got a head start on its goal at the outset of Earth Month, when Winterscheidt and a group of volunteers planted the first seeds in the expanded garden during a pair of community workdays. Sweet potatoes, tomatoes, strawberries, and various seeds are already in the ground, but plenty more fruits, vegetables, and herbs will be added soon.

In addition to a passion for gardening, Winterscheidt arrived at Tech at a time when many students were seeking ways to get outside during the pandemic. A lasting effect of the interruption has been an increase in the number of virtual events, but the garden provides the perfect opportunity to interact with nature and with other people. 

"We're trying to get people to come outside. Our goal is to get Georgia Tech students away from their computers, away from their homework, and to de-stress and get their hands in the soil," he said, adding that the workdays give students a chance to interact with others from different majors and backgrounds. "Come for a few hours, chat with people, and after two hours, you feel refreshed. It's a kind of group therapy."

Community workdays in the garden are typically held on Saturday mornings, depending on the weather.

Beginning with summer programming, SOS will partner with the Wellness Empowerment Center to highlight the mental and physical health benefits of gardening. They will also be emphasizing sustainability. The Community Garden is entirely permaculture friendly, meaning it's a pesticide-free environment, and seeds are planted with purpose.

"We're mimicking nature in how we plant things," Winterscheidt explained. “Rather than spraying with pesticide, I can plant a basil plant that will deter hornworms from our tomatoes. Rather than spraying with herbicides, we can pluck all the weeds off individually. It takes a lot longer, but it's much better for our soil. Rather than growing for maximum output, we're growing in a way that benefits our soil the most."

While largely student-run, the garden does require constant upkeep, so in years past, the summer months could be challenging. However, with the expansion, Tamsin Leavy has been brought on as staff member to support the garden year-round.

"Like any garden or farm space, you don't want to lose all your hard work to the elements or other pests that can quickly annihilate a crop. We have put a lot of effort into this space and are looking forward to watching it grow. No pun intended," Leavy said. "It would be devastating to lose it to the harsh Georgia summer sun, so we will all be working together to keep our garden growing."

Volunteer opportunities remain plentiful over the summer, and in the absence of a large contingent of students, Malte Weiland, senior sustainability project manager for Campus Services, welcomes Tech faculty and staff to lend a hand. He encouraged all Tech employees to reach out to assist the team in maintaining the space and even urges entire departments to inquire about outings that can serve as wellness and team-building exercises.

For those looking to get involved with the garden or learn more about its expansion, Friday's ribbon-cutting ceremony will begin at 2 p.m.

“We all hope that the garden will continue to be a community gathering space where not just horticultural and agricultural education can happen, but anything adjacent to it — discussion on composting, urban gardens, or food justice issues. And day-to-day, for Tech students, I hope it can be a space where they are comfortable, where they can come to smell the flowers, put their hands in the dirt — even if it's just for a few minutes between classes to de-stress and reconnect to the earth," Leavy said.

The Community Market is another resource that brings sustainably sourced food to the Tech community every Wednesday from 10 a.m. to 2 p.m. along Tech Walkway. The Office of Sustainability will wrap up the spring semester market at the end of April, but selective summer dates will be announced soon. When the market returns in the fall, Weiland said that vendors and patrons can expect several updates, including a market map, and students will be able to make purchases using dining dollars on their BuzzCards.

Students in Thomasville, Ga. present their own inventions as a part of Georgia Tech’s expanding K-12 InVenture Prize competition program.

Georgia Institute of Technology’s Center for Education Integrating Science, Mathematics, and Computing (CEISMC) is at the center of a new statewide initiative combining artificial intelligence and manufacturing innovations with transformational workforce development and K-12 outreach. The Georgia Artificial Intelligence Manufacturing Corridor project (Georgia AIM) is supported by a record-shattering $65 million grant Georgia Tech received in September 2022 from the U.S. Department of Commerce’s Economic Development Administration.

Georgia AIM will support a total of nine inter-related projects throughout the state and is designed to increase job and wage opportunities in distressed and rural communities and among historically underrepresented and underserved people. Georgia AIM targets rural residents, women, Black, Indigenous and People of Color (BIPOC), those living with disabilities, and veterans — groups historically underrepresented in manufacturing. Through innovation, collaboration, education, and participation, Georgia AIM will provide the tools and knowledge to empower these communities to participate fully in a diverse AI manufacturing workforce.

“Many people have preconceived notions about manufacturing and may not be able to see how they could possibly connect to it," said Roxanne Moore, Woodruff School of Mechanical Engineering’s senior research engineer and director of CEISMC’s K-12 InVenture Prize program. “What they may not realize is that manufacturing is what brings new ideas to life. AI is rapidly reshaping the manufacturing industry and changing the landscape for job opportunities. The work that we are doing will position Georgia to lead the nation into the future of AI and manufacturing.”

Moore explains that through Georgia AIM, CEISMC will expand its K-12 InVenture Prize invention and entrepreneurship program to collaborate with school districts and businesses in Southwest Georgia, Southeast Georgia and Northeast Georgia. The initiative will expand on existing partnerships Georgia Tech has established with technical colleges and minority-serving institutions.

The project will reach at least 1,000 K-12 students and 100 teachers from underserved areas, with a focus on rural communities via existing programs at Georgia Tech, other nonprofits, the Technical College System of Georgia, the Southwest Georgia Regional Commission, local manufacturers, and K-12 school leaders, Moore said.

“We need to illustrate the powerful relationships between innovation, entrepreneurship, and manufacturing so that students can see how ideas come to life and how they can improve their communities,” said Moore. “It is my hope that these regional ecosystems become a role model for how educational institutions can support each other in expanding access to high-quality STEM experiences for diverse students who typically are not empowered to create their futures.”

As part of Georgia AIM, CEISMC will also expand its offerings through partnerships with the institute’s GoSTEM program to better serve Latino populations. GoSTEM is a collaborative partnership at Georgia Tech between CEISMC and Institute Diversity, Equity and Inclusion (IDEI). Its mission is to promote STEM academic achievement and college attendance among Latino and other cultural and linguistic minority K-12 students. Plans include translating existing invention and entrepreneurship curriculum into Spanish, adding lessons to the curriculum on AI and manufacturing, assisting with the development of regionally focused curricula, and expanding training and events to make them more inclusive.

“Our goal is to make invention education accessible to everyone in the state, especially those who may have been previously left out of the conversation,” said Danyelle Larkin, educational outreach manager with CEISMC. “By going into more rural areas of the state and working to develop multi-lingual curricula that is focused on the needs of the region, we hope to serve as a national model for how to accelerate the transition to automation in manufacturing while diversifying the next generation of AI leadership.

Additional Georgia AIM expansion plans for CEISMC and K-12 InVenture Prize include supporting an existing high school entrepreneurship program in Fitzgerald and working with Albany State University to host teacher workshops, support local schools, and host regional competitions with a focus on inventiveness and the entrepreneurial mindset.

"The overall goal of Georgia AIM is to establish the United States as a leader in AI manufacturing while making sure that these systems complement rather than replace existing workers,” Larkin said. “The work that we are doing in CEISMC plays an integral role in Georgia AIM with our specific expertise in weaving invention education and entrepreneurship into K-12 classrooms and connecting with diverse communities. This huge grant gives us a chance to amplify our work and bring even more people into the AI conversation. It’s about building a better, more equitable future for the people of Georgia.”

Past and present power grid experts.     Top: Power systems experts from around the world gathering in St. Louis in 1904 to discuss anything and everything electrical, including the operation of the then new networks of synchronous generators.    Bottom: The January 2023 meeting of the Universal Interoperability for Grid-forming Inverters (UNIFI) Consortium on Georgia Tech’s campus in Atlanta. UNIFI is a U. S. Department of Energy funded effort to advance grid-forming (GFM) inverter technology.

The North American power grid is undergoing a generational transformation. Amid this change, an interdisciplinary research team of engineers and historians seeks to uncover the untold stories behind the algorithms and power systems architecture that have shaped the complex technological and social history of this key infrastructure.

“You can’t connect the dots looking forward; you can only connect them looking backwards.” These words, famously attributed to Steve Jobs, address the broad truth that only through intentional reflection and examination can we learn from the past.

With this in mind, an interdisciplinary research team comprised of engineers and historians from the Georgia Institute of Technology, the University of Houston, and the University of Minnesota are hoping to shape the future of electric power grids by studying and cataloguing the field’s robust history during a two-year study funded by the Alfred P. Sloan Foundation.

“While electrical engineering is at the forefront of many of today’s technological advancements, a critical step in the process of innovative and cutting-edge research is working to understand the past,” said Dan Molzahn, assistant professor in the Georgia Tech School of Electrical and Computer Engineering and the project’s principal investigator.

The group’s project, "Algorithms and Power Systems Architecture: Using Historical Analysis to Envision a Sustainable Future", emerges out of the Sloan Foundation’s emphasis to award historical scholarship projects that look to understand the contemporary context of scientific research and inform current and future research and policy practices. The study will examine the relatively invisible, yet central, role of the algorithms 20th-century engineers developed to provide optimization and control of the electric power grid and the ways in which these algorithms might impact the cleaner grid of the future.

“Clarifying how invisible technologies [like algorithms] became established in large and complex power systems is the ultimate goal of the project,” said Molzahn. “As algorithms became thoroughly naturalized within power systems architecture, they set the boundaries and established the scope of possibility; this can restrict innovation across the technology spectrum.”

The research team — two historians and two engineers — represents an innovative alliance of technical, historical, and public policy approaches. In addition to Molzahn, the team includes Sairaj Dhople, associate professor of electrical and computer engineering at the University of Minnesota (UMN); Julie Cohn, a research historian at the Center for Public History at the University of Houston (UH); and Monica Perales, associate professor of history and director of the Center for Public History at UH.

The project comes at a time when power grids are in the throes of new demands and transformation. As a result of aging technology and regulatory structures that impede upgrades of essential power infrastructure, current grids are inadequate in integrating renewable energy sources at the scale the market requires. Energy providers and researchers are also looking for ways to guard power systems against cyber assaults, as well as against an increased risk of extreme weather events due to climate change — the average overall duration of power interruptions due to weather in the U.S. doubled since 2015, according to the U.S. Department of Energy.

“The opportunities and challenges of widespread electrification are front and center for the public. Debates about climate change, opposition to large-scale energy infrastructure, and periodic weather-related power outages appear in the news regularly,” said Cohn, who is an expert on the development of the North American electric power grid and author of the book “The Grid” on the topic.

A particularly important part of the project is collecting the oral history of individuals who were instrumental in the development, adoption, and application of algorithms in North America. The team will train history and engineering graduate students to conduct approximately 50 interviews with members of the National Academy of Engineering, IEEE Fellows, and prominent power systems engineers.

“The interviews themselves will be the best way to make this project relevant for a non-technical audience,” said Perales, an expert on oral history methods. “When you hear a person tell their story about why they became interested in working on the power system, it is often more than a ‘technical’ story. They offer insight into the ‘why’, which is always compelling.”

The interviews will be archived at UH and the IEEE History Center, and will eventually be made available to other researchers and the public. The team will use the interviews as important source information to produce a podcast that interprets the highly technical history of algorithms and power systems architecture for a broad audience, especially those interested in climate change and sustainability.

The completed history will then be leveraged in engineering courses taught by Molzahn at Tech and Dhople at the UM with the hope that other institutions will utilize the team’s findings to provide appropriate historical context in their power engineering courses.

Researchers at the Georgia Tech Research Institute (GTRI) are using additive manufacturing techniques to create unique waveguide structures that would be difficult or impossible to make using conventional fabrication processes. The new techniques are especially useful for integrating updated components into equipment that might otherwise require significant design changes.

In high-powered millimeter wave and microwave radars and antennas, waveguides direct electromagnetic energy from one component to another inside the equipment. Until recently, the waveguides had been fabricated from extruded copper or aluminum tubing, but these traditional manufacturing techniques can’t always accommodate the complex configurations needed for optimal design with minimal energy transmission losses.

“To propagate electromagnetic waves efficiently, the waveguide must have a very precise internal geometry,” explained GTRI Senior Research Engineer Kyle Azevedo. “Yet, the waveguide must also be very smooth in terms of its internal surface finish. The cavity that transmits the energy has to be very well controlled to avoid significant losses. And the waveguides must also fit into confined spaces.”

Additive Techniques Offer Specific RF Advantages

To allow more complex designs, GTRI researchers are evaluating two alternative fabrication techniques: 3D-printed structures fabricated from metal and 3D-printed polymer components that are metal coated. Each has advantages and disadvantages and must be chosen for the specific application. The researchers are testing waveguides made using both techniques for mechanical performance in resisting fatigue damage, thermal performance in dissipating heat, electrical performance – and their RF energy loss.

Flexibility afforded by additive techniques can help designers accommodate waveguides within a crowded design that includes many other components. In one current project, the researchers found that they needed to move a radar’s feed horn several inches to accommodate other design considerations. But that complicated the waveguide design.

“That was a really big challenge, because we had to change some of the existing waveguides, and we couldn’t do that with traditional tubing pieces that were available without coming up with a whole new design,” Azevedo said. “But by using additive processes that allow more customization, we were able to make things smaller and optimize the design in a single iteration.”

In another project – in consideration for use on Army counter-battery radar – researchers at U.S. Army DEVCOM C5ISR Center used additive techniques to accommodate an updated component of a different size and shape than the original to improve RF performance. The researchers designed a 3D-printed waveguide that accommodated the existing connectors and integrated into its legacy systems, then worked with the Army’s Rock Island Arsenal to optimize fabrication and quality control. That new component was successfully tested at Tobyhanna Army Depot and Yuma Proving Ground, and is now being evaluated as an OEM alternative. This may allow additive manufacturing to augment the supply system.

In addition to facilitating designs that might otherwise have been more challenging, the GTRI researchers expect additive manufacturing will allow them to accelerate the iterative development of prototypes by moving some waveguide fabrication in-house.

Overcoming Challenges with New Fabrication Methods

For all-metal waveguides, additive manufacturing can have some disadvantages, but those may not be as significant as they might first appear. To limit transmission losses, inside surfaces of conventional waveguides are smooth, but because of the way metal 3D printing works, smooth internal surfaces can be difficult to fabricate. The design flexibility of additive processes can make up for that.

“In one of our designs, we found that even though we might have some limitations on the roughness of the surface finish, we could gain back the transmission losses by optimizing the waveguide shape,” Azevedo explained. “The final design would not have been possible using traditional waveguide fabrication techniques.”

Though applying metal coatings to waveguides produced from polymers or resins can provide smoother surfaces, this process comes with its own set of challenges.

“One of the issues we are tackling now is that a lot of the resins and polymers that have desirable properties for plating contain silica,” said Max Tannenbaum, a GTRI research engineer. “They are ceramic-like when cured, but when you remove the resin, a lot of the conventional solvents don’t remove the silica, and you end up with a chalky powder on the surface. If you can’t remove that before you try to plate it, the plating won’t adhere.”

Building a Knowledge Base for RF Applications of Additive Processes

To support expanded applications for waveguides fabricated using additive techniques, the researchers are using both simulation and experimentation to develop comprehensive design information.

“The traditional method for making waveguides has been around since World War II, when the original systems got up and running, and those techniques have been refined over the decades since then,” said Azevedo. “As a result, there’s a wealth of detailed data on what works, including the metallurgic properties. We want to develop a comparable depth of understanding for the new additive manufacturing techniques that offer so many advantages.” By putting together what they have learned, the research team plans to share their knowledge with other RF engineers who may be interested in the additive approaches.

“Our effort is focusing on two parallel paths: looking at the mechanical constraints involved with fabrication and the RF limitations,” said GTRI Research Engineer Austin Forgey. “We are merging the new experimental data we’re getting with RF simulations, and combining that with testing mechanical properties. That will give us a full design package that can be used by the designers who need it.”

Beyond waveguides, the GTRI researchers are working on other applications of additive manufacturing to RF design. With researchers in Georgia Tech’s School of Mechanical Engineering, they are fabricating cold plates that are 3D printed from aluminum and used to cool high-powered electronics. The 3D printing allows novel fluid flow in a single part, not possible with conventional fabrication.

Similarly, they are also looking at additive techniques to make shielding needed to protect components from electromagnetic interference.

While they expect to expand their use of additive fabrication approaches to provide new design options for RF applications, the researchers don’t see additive manufacturing doing away with conventional fabrication techniques any time soon.

“My opinion is that there will certainly be a mix because additive manufacturing techniques aren’t the answer for everything,” said Tannenbaum. “But they are solutions to a lot of specific problems that we encounter, allowing us to build parts that are cheaper, lighter, and available more quickly.”

Hybrid Electric Bus

The Division of Student Engagement and Well-Being is excited to welcome a new hybrid Stinger bus to campus. The EZ Rider II was unveiled this week and added to the Gold Route as Georgia Tech Parking and Transportation Services (PTS) takes another step toward decreasing its carbon footprint by reducing greenhouse gas emissions.

According to senior director of PTS, Sherry Davidson, “Our transportation team took a hard look at how we could build the future that we all wanted to see. The result was changing the way in which we operate. Moving to hybrid improves sustainability while maintaining fiscal responsibility.”

PTS is continually looking for ways to reduce its environmental impact, and this new bus is a significant step in that direction. One of the key advantages is its zero-emission electric mode, which allows the bus to operate fully electric for about 20% of the route. This not only helps to improve air quality but also reduces noise pollution.

“Hybrid” means that this new bus can switch between electric and gasoline power as needed, reducing emissions and increasing fuel efficiency. It also features advanced technologies such as regenerative braking, which captures energy normally lost during braking and uses it to recharge the bus's batteries. This not only improves fuel economy but also extends the life of the bus's braking system.

This new bus will also allow PTS to improve the customer experience and the efficiency of the overall transportation system. It also features automated passenger counters, automated stop announcements, and bike racks, and its low floor ramp will improve accessibility and ease of boarding for passengers. 

This new addition to the Gold Route is the first of nine hybrid buses to come to the Georgia Tech campus. The remaining fleet will arrive in April.
