A Rice University chemist James Tour has secured a new $12 million cooperative agreement with the U.S. Army Engineer Research and Development Center on the team’s work to efficiently remove pollutants from soil.

The four-year agreement will support the team’s ongoing work on removing per- and polyfluoroalkyl substances (PFAS) from contaminated soil through its rapid electrothermal mineralization (REM) process, according to a statement from Rice.

Traditionally PFAS have been difficult to remove by conventional methods. However, Tour and the team of researchers have been developing this REM process, which heats contaminated soil to 1,000 C in seconds and converts it into nontoxic calcium fluoride efficiently while also preserving essential soil properties.

“This is a substantial improvement over previous methods, which often suffer from high energy and water consumption, limited efficiency and often require the soil to be removed,” Tour said in the statement.

The funding will help Tour and the team scale the innovative REM process to treat large volumes of soil. The team also plans to use the process to perform urban mining of electronic and industrial waste and further develop a “flash-within-flash” heating technology to synthesize materials in bulk, according to Rice.

“This research advances scientific understanding but also provides practical solutions to critical environmental challenges, promising a cleaner, safer world,” Christopher Griggs, a senior research physical scientist at the ERDC, said in the statement.

Also this month, Tour and his research team published a report in Nature Communications detailing another innovative heating technique that can remove purified active materials from lithium-ion battery waste, which can lead to a cleaner production of electric vehicles, according to Rice.

“With the surge in battery use, particularly in EVs, the need for developing sustainable recycling methods is pressing,” Tour said in a statement.

Similar to the REM process, this technique known as flash Joule heating (FJH) heats waste to 2,500 Kelvin within seconds, which allows for efficient purification through magnetic separation.

This research was also supported by the U.S. Army Corps of Engineers, as well as the Air Force Office of Scientific Research and Rice Academy Fellowship.

Last year, a fellow Rice research team earned a grant related to soil in the energy transition. Mark Torres, an assistant professor of Earth, environmental and planetary sciences; and Evan Ramos, a postdoctoral fellow in the Torres lab; were given a three-year grant from the Department of Energy to investigate the processes that allow soil to store roughly three times as much carbon as organic matter compared to Earth's atmosphere.

By analyzing samples from the East River Watershed, the team aims to understand if "Earth’s natural mechanisms of sequestering carbon to combat climate change," Torres said in a statement.

United breaks ground on $177 million facility and opens tech center at IAH

off the ground

United Airlines announced new infrastructure investments at George Bush Intercontinental Airport as part of the company’s ongoing $3.5 billion investment into IAH.

United broke ground on a new $177 million Ground Service Equipment (GSE) Maintenance Facility this week that will open in 2027.

The 140,000-square-foot GSE facility will support over 1,800 ground service vehicles and with expansive repair space, shop space and storage capacity. The GSE facility will also be targeted for LEED Silver certification. United believes this will provide more resources to assist with charging batteries, fabricating metal and monitoring electronic controls with improved infrastructure and modern workspaces.

Additionally, the company opened its new $16 million Technical Operations Training Center.

The center will include specialized areas for United's growing fleet, and advanced simulation technology that includes scenario-based engine maintenance and inspection training. By 2032, the Training Center will accept delivery of new planes. This 91,000-square-foot facility will include sheet metal and composite training shops as well.

The Training Center will also house a $6.3 million Move Team Facility, which is designed to centralize United's Super Tug operations. United’s IAH Move Team manages over 15 Super Tugs across the airfield, which assist with moving hundreds of aircraft to support flight departures, remote parking areas, and Technical Operations Hangars.

The company says it plans to introduce more than 500 new aircraft into its fleet, and increase the total number of available seats per domestic departure by nearly 30%. United also hopes to reduce carbon emissions per seat and create more unionized jobs by 2026.

"With these new facilities, Ground Service Equipment Maintenance Facility and the Technical Operations Training Center, we are enhancing our ability to maintain a world-class fleet while empowering our employees with cutting-edge tools and training,” Phil Griffith, United's Vice President of Airport Operations, said in a news release. “This investment reflects our long-term vision for Houston as a critical hub for United's operations and our commitment to sustainability, efficiency, and growth."

Malaysia’s government has given final approval for a Texas-based marine robotics company to renew the search for Malaysia Airlines Flight 370, which is believed to have crashed in the southern Indian Ocean more than a decade ago.

Cabinet ministers agreed to terms and conditions for a “no-find, no-fee” contract with Texas-based Ocean Infinity to resume the seabed search operation at a new 5,800-square-mile site in the ocean, Transport Minister Anthony Loke said in a statement. Ocean Infinity will be paid $70 million only if wreckage is discovered. Continue reading.

UH study uncovers sustainable farming methods for hemp production

growth plan

A new University of Houston study of hemp microbes can potentially assist scientists in creating special mixtures of microbes to make hemp plants produce more CBD or have better-quality fibers.

The study, led by Abdul Latif Khan, an assistant professor of biotechnology at the Cullen College of Engineering Technology Division, was published in the journal Scientific Reports from the Nature Publishing Group. The team also included Venkatesh Balan, UH associate professor of biotechnology at the Cullen College of Engineering Technology Division; Aruna Weerasooriya, professor of medicinal plants at Prairie View A&M University; and Ram Ray, professor of agronomy at Prairie View A&M University.

The study examined microbiomes living in and around the roots (rhizosphere) and on the leaves (phyllosphere) of four types of hemp plants. The team at UH compared how these microorganisms differ between hemp grown for fiber and hemp grown for CBD production.

“In hemp, the microbiome is important in terms of optimizing the production of CBD and enhancing the quality of fiber,” Khan said in a news release. “This work explains how different genotypes of hemp harbor microbial communities to live inside and contribute to such processes. We showed how different types of hemp plants have their own special groups of tiny living microbes that help the plants grow and stay healthy.”

The study indicates that hemp cultivation can be improved by better understanding these distinct microbial communities, which impact growth, nutrient absorption, stress resilience, synthesis and more. This could help decrease the need for chemical inputs and allow growers to use more sustainable agricultural practices.

“Understanding these microorganisms can also lead to more sustainable farming methods, using nature to boost plant growth instead of relying heavily on chemicals,” Ahmad, the paper’s first author and doctoral student of Khan’s, said the news release.

Other findings in the study included higher fungal diversity in leaves and stems, higher bacterial diversity in roots and soil, and differing microbiome diversity. According to UH, CBD-rich varieties are currently in high demand for pharmaceutical products, and fiber-rich varieties are used in industrial applications like textiles.
