Rice University researchers have teamed up with South Korean scientists to develop the first eco-friendly technology that captures and destroys toxic “forever chemicals,” or PFAS, in water.

PFAS have been linked to immune system disruption, certain cancers, liver damage and reproductive disorders. They can be found in water, soil and air, as well as in products like Teflon pans, waterproof clothing and food packaging. They do not degrade easily and are difficult to remove.

Thus far, PFAS cleanup methods have relied on adsorption, in which molecules cling to materials like activated carbon or ion-exchange resins. But these methods tend to have limited capacity, low efficiency, slow performance and can create additional waste.

The Rice-led study, published in the journal Advanced Materials, centered on a layered double hydroxide (LDH) material made from copper and aluminum that could rapidly capture PFAS and be used to destroy the chemicals.

The study was led by Rice professor Youngkun Chung, a postdoctoral fellow under the mentorship of Michael S. Wong. It was conducted in collaboration with Seoktae Kang, professor at the Korea Advanced Institute of Science and Technology, and Keon-Ham Kim, professor at Pukyung National University, who first discovered the LDH material.

The team evaluated the LDH material in river water, tap water and wastewater. And, according to Rice, that material’s unique copper-aluminum layers and charge imbalances created an ideal binding environment to capture PFAS molecules.

“To my astonishment, this LDH compound captured PFAS more than 1,000 times better than other materials,” Chung, lead author of the study and now a fellow at Rice’s WaTER (Water Technologies, Entrepreneurship and Research) Institute and Sustainability Institute, said in a news release. “It also worked incredibly fast, removing large amounts of PFAS within minutes, about 100 times faster than commercial carbon filters.”

Next, Chung, along with Rice professors Pedro Alvarez and James Tour, worked to develop an eco-friendly, sustainable method of thermally decomposing the PFAS captured on the LDH material. They heated saturated material with calcium carbonate, which eliminated more than half of the trapped PFAS without releasing toxic by-products.

The team believes the study’s results could potentially have large-scale applications in industrial cleanups and municipal water treatments.

“We are excited by the potential of this one-of-a-kind LDH-based technology to transform how PFAS-contaminated water sources are treated in the near future,” Wong added in the news release. “It’s the result of an extraordinary international collaboration and the creativity of young researchers.”

Rice University announced a new research center that will focus on per- and polyfluoroalkyl substances (PFAS) called the Rice PFAS Alternatives and Remediation Center (R-PARC).

R-PARC promises to unite industry, policy experts, researchers, and entrepreneurs to “foster collaboration and accelerate the development of innovative solutions to several PFAS challenges,” according to a news release. Challenges include comprehensive PFAS characterization and risk assessment, water treatment infrastructure upgrades, contaminated site remediation, and the safe alternatives development.

“We firmly believe that Rice is exceptionally well-positioned to develop disruptive technologies and innovations to address the global challenges posed by PFAS,” Rice President Reginald DesRoches says in a news release. “We look forward to deepening our relationship with ERDC and working together to address these critical challenges.”

The Environmental Protection Agency issued its stringent standards for some of the most common PFAS, which set the maximum contaminant level at 4.0 parts per trillion for two of them. Pedro Alvarez, Rice’s George R. Brown Professor of Civil and Environmental Engineering, director of the WaTER Institute, likened this in a news release to “four drops in 1,000 Olympic pools,” and also advocated that the only way to meet these strict standards is through technological innovation.

The center will be housed under Rice’s Water Technologies Entrepreneurship and Research (WaTER) Institute that was launched in January 2024. The WaTER Institute has worked on advancements in clean water technology research and applications established during the decade-long tenure of the Nanosystems Engineering Research Center for Nanotechnology Enabled Water Treatment, which was funded by the National Science Foundation.

“The challenge of PFAS cuts across several of the four major research trajectories that define Rice’s strategic vision,” Rice’s executive vice president for research and professor of materials science and nanoengineering and physics and astronomy Ramamoorthy Ramesh, adds in the release. “R-PARC will help focus and amplify ongoing work on PFAS remediation at Rice.”

The ERDC delegation was led by agency director David Pittman who also serves as the director of research and development and chief scientist for the U.S. Army Corps of Engineers. ERDC representatives also met with several Rice researchers that were involved in work related to the environment, and sustainability, and toured the labs and facilities.

3 Houston sustainability startups score prizes at Rice University pitch competition

seeing green

A group of Rice University student-founded companies shared $100,000 of cash prizes at an annual startup competition — and three of those winning companies are focused on sustainable solutions.

Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge, hosted by Rice earlier this month, named its winners for 2024. HEXASpec, a company that's created a new material to improve heat management for the semiconductor industry, won the top prize and $50,000 cash.

Founded by Rice Ph.D. candidates Tianshu Zhai and Chen-Yang Lin, who are a part of Lilie’s 2024 Innovation Fellows program, HEXASpec is improving efficiency and sustainability within the semiconductor industry, which usually consumes millions of gallons of water used to cool data centers. According to Rice's news release, HEXASpec's "next-generation chip packaging offer 20 times higher thermal conductivity and improved protection performance, cooling the chips faster and reducing the operational surface temperature."

A few other sustainability-focused startups won prizes, too. CoFlux Purification, a company that has a technology that breaks down PFAS using a novel absorbent for chemical-free water, won second place and $25,000, as well as the Audience Choice Award, which came with an additional $2,000.

Solidec, a company that's working on a platform to produce chemicals from captured carbon, and HEXASpec won Outstanding Achievement in Climate Solutions Prizes, which came with $1,000.

The NRLC, open to Rice students, is Lilie's hallmark event. Last year's winner was fashion tech startup, Goldie.

“We are the home of everything entrepreneurship, innovation and research commercialization for the entire Rice student, faculty and alumni communities,” Kyle Judah, executive director at Lilie, says in a news release. “We’re a place for you to immerse yourself in a problem you care about, to experiment, to try and fail and keep trying and trying and trying again amongst a community of fellow rebels, coloring outside the lines of convention."

This year, the competition started with 100 student venture teams before being whittled down to the final five at the championship. The program is supported by Lilie’s mentor team, Frank Liu and the Liu Family Foundation, Rice Business, Rice’s Office of Innovation, and other donors

“The heart and soul of what we’re doing to really take it to the next level with entrepreneurship here at Rice is this fantastic team,” Peter Rodriguez, dean of Rice Business, adds. “And they’re doing an outstanding job every year, reaching further, bringing in more students. My understanding is we had more than 100 teams submit applications. It’s an extraordinarily high number. It tells you a lot about what we have at Rice and what this team has been cooking and making happen here at Rice for a long, long time.”
