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.”

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”

Rice University to lead AI conferences in Paris this spring and summer

where to be

Houston’s own Rice University will host a series of conferences on artificial intelligence in Paris, France, starting this month. The series will tackle the impact and possibilities of AI in fields like econometrics and online privacy security.

“Artificial intelligence is transforming the global economy and raising profound questions about how technology intersects with society,” Caroline Levander, Rice’s vice president for global strategy, said in a news release. “By convening scholars from multiple disciplines and countries in Paris, Rice is helping shape the international conversation about how AI should be developed, governed and used.”

The four conferences in Paris aim for a multi-disciplinary approach that tackles aspects of AI from diverging angles. The conferences come as part of Rice’s increased partnership with French researchers at the Université Paris Sciences & Lettres. The two institutions have formed a binary star system of academic sharing and support.

“Paris has quickly become one of the most important global hubs for artificial intelligence research, entrepreneurship and policy,” Levander said. “For Rice, having a presence in the city allows our scholars to engage directly with that ecosystem while building collaborations that connect Europe and the United States around the future of AI.”

The conferences will be held at the Rice Global Paris Center. Topics scheduled are:

Emerging Topics in Operations Management: Platforms, Blockchains and AI

April 27-29

This conference will focus on how companies like Uber, Airbnb, Spotify, and DoorDash can use blockchain ledgers to deliver goods and services more transparently. It will also look at tokenized incentives, presumably forms of cryptocurrency and non-fungible tokens in the app space.

Econometrics and AI

May 5-7

This conference will explore how AI can be used in various economic statistical models and practices.

Human Flourishing in the Age of AI

June 3-5

This conference will be a collaboration between engineers and philosophers about the ethics and impact of AI on the lives of its users.

On the Crossroads of AI and Society: Incentives, Privacy and Fairness

July 15-16

This conference will consider how to stakeholders can ensure AI’s actions most benefit people, particularly in the fields of healthcare education, energy and public policy.

Houston claims 19% of Texas’ new live-work-play growth

by the numbers

In Texas, Houston is a big player in the live-work-play real estate movement.

A new 21-city analysis from coworking marketplace CoworkingCafe shows the Houston area added five live-work-play projects—mixed-use developments with residential, office and recreational components—over the past decade.

From 2016 to 2025, Houston accounted for 19 percent of Texas’ new live-work-play inventory, the analysis shows. Among the new local developments were Arrive Upper Kirby, St. Andrie, and The Laura:

  • Arrive Upper Kirby, which was sold in 2021 for $182 million, offers more than 61,000 square feet of retail and restaurant space adjacent to apartments and offices. The 13-story, 265,000-square-foot project was completed in 2017.
  • St. Andrie, a 32-acre, mixed-use community, was completed in 2019. The apartment-anchored development includes an H-E-B grocery store and 37,000 square feet of office space.
  • The Laura, spanning 110,000 square feet, was completed in 2023. Among the apartment complex’s amenities is a coworking space.

According to Northspyre, a software provider for real estate developers, live-work-play projects enable people to meet their needs, such as housing, workplaces, stores, restaurants, and recreation facilities, in a single place.

A total of 542 live-work-play developments opened between 2016 and 2025 in the 21 cities, with another 69 in the pipeline for 2026, CoworkingCafe says. Among major markets, New York City made up the largest share (119) of new live-work-play developments from 2016 to 2025.

The Houston area’s five projects were built in 2018, 2019, 2020, 2024, and 2025, CoworkingCafe data indicates, with another project scheduled for completion next year. The Greater Houston Partnership recently highlighted four mixed-use projects taking shape in the region, but only one of them is scheduled to be finished in 2027. It can take two to five years or more to complete a mixed-use development.

Of the five Houston developments finished in the past decade, 56 percent of the space went toward multifamily units, 29 percent toward offices, and 16 percent toward retail, CoworkingCafe says.

As noted by the Houston-Galveston Area Council, economic development in the 21st century “is about cultivating quality live-work-play environments that attract, retain, and grow a diverse and skilled population. Employers and businesses are increasingly choosing to make long-term investments in places that connect and engage people to strengthen economic competitiveness and promote innovation.”

With eight completed projects, Austin led construction of live-work-play developments in Texas from 2016 to 2025, according to CoworkingCafe. Dallas, which welcomed five live-work-play developments during that period, tied with Houston. San Antonio data wasn’t available.
