NUS researchers develop new aerogels for radiative cooling and the absorption of electromagnetic waves

Published

Two new studies demonstrate how aerogels could provide cooling to buildings and protection from harmful electromagnetic waves emitted by electronic devices

SINGAPORE, June 4, 2024 /PRNewswire/ — Aerogels, known for their porosity and low density, are solid materials that offer versatile functionality — from gobbling up fat globules in weight-management supplements to facilitating more sustainable metal-recycling processes. Traditionally used to provide thermal insulation in the aerospace industry, scientists from the National University of Singapore (NUS) have taken the material to the next level — harnessing its unique properties to provide value to numerous applications in building and construction, environmental remediation, drug delivery, and even clothing and textiles.

In a pioneering effort, a research team led by Associate Professor DUONG Hai-Minh from the Department of Mechanical Engineering under the NUS College of Design and Engineering, has developed aerogels for two new applications: radiative cooling and electromagnetic wave (EMW) absorption.

Utilising plastic waste, the team engineered thin-film aerogels that function as thermal insulators and radiative coolers. These aerogels can be applied to any surface, such as building roofs, to reduce internal temperatures, offering a scalable and sustainable solution for energy-free thermal management. The team’s findings were published in the journal Solar Energy on 15 May 2024.

In another study, published in the journal Carbon on 10 January 2024, the NUS researchers devised a simple, scalable method to produce aerogels that absorb EMWs in the X-band, characteristic of those used in weather monitoring and air traffic control. These lightweight, durable aerogels protect against electromagnetic pollution, shielding both humans and sensitive equipment in our increasingly digital world.

The researchers’ work builds on their prior successes in developing aerogels from a variety of waste materials, from plastics and paper to agricultural by-products such as pineapple leaves.

Aerogels for radiative cooling

Traditional cooling systems, such as air conditioners, have a ravenous appetite for energy, accounting for approximately 20% of electricity used in buildings worldwide. The new aerogels developed by the NUS team present a passive cooling alternative, leveraging the natural process of radiative cooling to dissipate heat into space without consuming energy.

“This process involves using specially engineered aerogels to emit infrared radiation through the atmospheric ‘sky window’, effectively cooling surface temperatures below ambient levels,” said Assoc Prof Duong. “We are excited to be able to upcycle fibres from disposable polyethylene terephthalate (PET) bottles for the new aerogels designed for this purpose, to help address the global plastic waste crisis.”

Previously the team had worked with PET fibres to produce aerogels, but this latest method is significantly more energy-efficient, consuming about 97 per cent less energy and reducing production time by 96 per cent. When tested in Singapore’s warm climate, conducted in collaboration with Dr Jaesuk HWANG from the Centre for Quantum Technologies at NUS, 0.5 centimetres of the material produced a cooling effect of 2 degrees Celcius, achieved by emitting infrared heat into the surroundings while exhibiting good heat insulation, preventing heat absorption from the surrounding environment.

“These aerogels could reduce energy consumption in both residential and commercial buildings, especially in tropical climates where cooling is now a necessity,” added Assoc Prof Duong.

Future research will focus on adapting these aerogels for diverse climatic conditions and expanding their applications beyond building insulation, such as in industrial processes where the efficient thermal management of liquid circulation pipes is crucial.

Aerogels for electromagnetic wave absorption

Modern electronic devices emit EMWs that can disrupt nearby equipment and pose health risks, including DNA damage and cancer. It is critical, therefore, to develop materials that can effectively absorb EMWs to shield both humans and infrastructure from these adverse effects. Applications include enhancing the privacy and security of buildings as well as protecting sensitive medical equipment.

To address this need, Assoc Prof Duong’s team has developed a scalable and eco-friendly procedure to produce novel aerogels that are effective at EMW absorption. The process involves blending three main components — carbon nanotubes, polyvinyl alcohol and carboxymethyl cellulose — followed by freeze-drying.

The aerogel, with a thickness of about 3 millimetres — roughly the width of 40 strands of human hair — demonstrated an impressive performance of absorbing 99.99 per cent of EMW energy. Across the entire X-band (8.2­–12.4 GHz) of the electromagnetic spectrum, used primarily for radar systems, weather monitoring and air traffic control, the aerogel consistently showed its ability to absorb 90 per cent of EMW energy.

“In addition to offering a wide absorption bandwidth of 1.2–2.2 GHz in the X-band, our aerogel is also about 10 times lighter than existing composites used for EMW absorption,” added Assoc Prof Duong. “Unlike other composites, our aerogel requires no mixing with heavy polymer fillers before use.”

The researchers have estimated that producing one square metre of the aerogel, with a thickness of one centimetre, costs less than US$74. This cost is substantially lower than the price of other similar commercial materials, which could range from US$133 to above US$738.

Looking ahead, the team plans to refine the aerogel’s mechanical properties, such as flexibility, to broaden their applicability across various building and infrastructure projects. The researchers also aim to conduct real-world tests to fully assess the EMW absorption capabilities of the aerogels in practical scenarios.

By

AUBURN, Ala., April 22, 2026 /PRNewswire/ — As Artificial Intelligence (AI) becomes more integrated into daily life, Auburn University’s College of Education is sharpening its focus on this powerful tool and exploring how it can strengthen the preparation of future educators and healthcare workers.

Throughout the College of Education (and featured in the recent release of the college’s Keystone Magazine), artificial intelligence is being thoughtfully integrated across its four academic units, reflecting both the breadth of the college and a shared commitment to ethical, human-centered practice. Auburn College of Education Dean Jeffrey Fairbrother shared his perspective on how artificial intelligence aligns with the college’s vision for the future.

“In the College of Education, we’re committed to opening doors and improving lives, and artificial intelligence is an important door to opportunity,” he said. “I am proud of our faculty who are embracing AI to expand access, enhance learning and empower educators, always guided by ethics and integrity. By opening these doors today, we’re building a better future for all, far into the future.”

In the Department of Curriculum and Teaching, faculty are focused on teacher preparation and continuously improving methods of learning. Paul Fitchett, head of C&T, oversees several faculty members leading AI-focused initiatives, including some who are developing a course on the applied use of AI in the workplace that will come with industry credentialing.

“We are exploring AI through a number of different, applied facets,” Fitchett said. “Some individuals are leveraging AI to expand research capabilities while others are engaging AI to support teaching and learning, improving the educational experience for instructors and students alike.”

In Agricultural Education, Leadership and Communications, AI is treated as both a research tool and an object of study, with faculty developing a new AI course and even patent-pending technologies that support agriculture, Extension work and global food systems, always emphasizing the “expert in the loop” and transparency over blind automation. In Elementary Education, future teachers learn to use AI as a collaborative planning and efficiency tool, refining outputs through pedagogical expertise and deep knowledge of learners.

Margaret Flores, interim head of the Department of Special Education, Rehabilitation, and Counseling, emphasized the importance of research regarding how AI will impact these professions. SERC faculty members are working to integrate AI into their classrooms to inform their students about future uses in their careers.

In Clinical Rehabilitation Counseling, faculty are embedding AI directly into applied coursework, training students to critically evaluate AI-generated vocational data, labor market information and assessment recommendations while grounding decisions in professional judgment and ethics. In the School Counseling Program, students are prepared to navigate AI’s possibilities and limits through ethics-focused coursework and national research, reinforcing that empathy, nuance and confidentiality remain irreplaceable.

Meanwhile, the Education to Accomplish Growth in Life Experiences for Success (EAGLES) Program is leveraging AI as an equalizer for students with intellectual disabilities, using federally funded digital literacy and AI modules to promote independence, self-advocacy and access.

“AI can enhance the services or instruction that we provide, reduce administrative tasks and increase efficiency in research,” Flores said. “We must ensure that researchers are shaping how AI is changing our fields.”

In the Department of Educational Foundations, Leadership, and Technology, faculty are working with AI in multiple ways. Through basic and applied research, faculty are addressing early childhood vocabulary learning and mathematics learning, and learning how AI can help with research workflow, STEM learning and even the development of education policy.

Several faculty members are also incorporating AI into their classrooms, including the use of an AU tutor to support independent learning and AI-explicit language in teaching materials such as syllabi.

EFLT Department Head Hank Murrah said that his unit’s approach is about embracing the changes that come with AI while also working to shape how it will affect the future of education.

“We view AI as both a transformative research tool and a catalyst for innovation in teaching and learning,” Murrah said. “Our faculty are developing AI-driven interventions for STEM education, leveraging AI to streamline research workflows and exploring ethical frameworks for its use in classrooms. These efforts position us to prepare graduates who are not only AI-literate but capable of shaping evidence-based policy and practice. We believe AI will redefine how educators design learning experiences and how researchers generate insights—making education more adaptive, fair and impactful.”

Matt Miller serves as the director of the School of Kinesiology, whose faculty members are exploring how AI can help with conducting research and processing data to find ways to improve a person’s health. Within the School of Kinesiology, AI is being introduced in coursework related to exercise prescription and programming, helping students analyze data, tailor training plans and think critically about how emerging technologies can support safe, individualized, evidence-based practice.

“School of Kinesiology faculty members conduct research that yields large and complex datasets involving measures related to human movement, including but not limited to their physical activity throughout the day, brain activity during exercise, joint angles while walking or throwing a ball and protein expression after exercise training,” Miller said. “AI helps faculty members make sense of these measures to translate research findings into practical knowledge that can be used to enhance health and performance.”

Additionally, in the School of Kinesiology, the Sensorimotor and Rehabilitation (SMART) Neuroscience Lab studies the neuroscience of human movement using virtual and augmented reality simulations. And now, a new member of the lab has joined the team to help understand things like balance and walking: Circuit, the robotic “dog” who comes complete with artificial intelligence built in. Circuit is what’s called a quadruped robot (“robot dog”), and he’s used to explore new ways of supporting older adults’ safety at home.

Led by Director of Physical Therapy Harsimran Baweja, the SMART Neuroscience Lab is using Circuit to study whether robot dogs equipped with artificial intelligence and advanced sensors can reliably track human movement during everyday activities.

While there are many uses for AI, College of Education faculty members are also acutely aware that the human touch is an essential part of their work. The overall goal is to use AI to enhance the service provided to another human being, whether they are a student or a patient.

“Whatever their approach, integrity and professional ethics remain the driving force for our use of generative Artificial Intelligence,” Fitchett said. “Maintaining these principles is essential as we navigate an ever-changing landscape.”

Together, these efforts highlight a college-wide approach to AI that spans disciplines and populations, using emerging technologies not as replacements for human expertise, but as tools to expand opportunity, insight and impact.
