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.

A huge technology question mark within business has been blockchain — how it'll affect the sharing of information and industry as a whole. But, one University of Houston professor and his Texas A&M University colleagues are looking into that potential disruption in a recent paper.

"It's an emerging technology. It's evolving," says Weidong "Larry" Shi, associate professor of computer science at UH, in a UH news release.

Funded by the Borders, Trade, and Immigration Institute, the research has developed into the paper, which was published in the International Journal of Production Research.

A key focus of the research is how blockchain will affect cargo entering the United States, and identifies six pain points within adapting blockchain for cargo management: traceability, dispute resolution, cargo integrity and security, supply chain digitalization, compliance, and trust and stakeholder management, according to the release.

"The wide adoption of blockchain technology in the global SC (supply chain) market is still in its infancy," the article reads. "Industry experts project that on average, it may take about six years for the widespread adoption of blockchain."

Blockchain has the potential to prevent fraud within the global supply chain, among other things.

"The data can't be changed. Everyone (along the supply chain) has a copy. You can add information, but you can't change it," Shi says in the release.

The U.S. Army taps Rice University for network research

Rice University and the U.S. Army have joined forces for a five-year, $30 million research agreement to modernize the Army — specifically for developing next-generation wireless networks and radio frequency (RF) electronics.

"[The Army Research Laboratory] and Rice will match the right people and capabilities to meet specific challenges, and the cooperative agreement is structured to allow the Army to partner widely across our campus," says Yousif Shamoo, Rice's vice president of research and lead on the ARL partnership, in a recent news release. "One exciting aspect of this partnership is the broader societal benefits. The technologies we're starting with are needed for Army modernization and they could also benefit millions of Americans in communities that still lack high-speed internet."

Without going into too much detail, the two entities are working to advance the Army's existing infrastructure to create networks that can sense attacks and protect themselves by adaption or stealth. The technology has the potential to affect the Army as well as civilians, says Heidi Maupin, the lead ARL contact for the Rice partnership.

"We want to deliver the capability of quickly deploying secure, robust Army communications networks wherever and whenever they're needed," Maupin says in the release. "The technology needed for that will benefit the world by transforming the economics of rural broadband, reducing response times to natural disasters, opening new opportunities for online education and more."

Research out of Baylor College of Medicine advancing information known about vision

For humans, seeing is pretty simple — just open your eyes. But the process our eyes go through extremely complex, and scientists have had a hard time recreating the process — until now.

Researchers at Baylor College of Medicine in Houston and the University of Tübingen in Germany have developed a novel computational approach that accelerates the brain's ability to identify optimal stimuli. The complete study by the scientists was published in the journal Nature Neuroscience.

"We want to understand how vision works," says senior author Dr. Andreas Tolias, professor and Brown Foundation Endowed Chair of Neuroscience at Baylor. "We approached this study by developing an artificial neural network that predicts the neural activity produced when an animal looks at images. If we can build such an avatar of the visual system, we can perform essentially unlimited experiments on it. Then we can go back and test in real brains with a method we named 'inception loops."

To track neurons and how they work, the researchers tracked brain activity scanning thousands of images.

"Experimenting with these networks revealed some aspects of vision we didn't expect," says Tolias, founder and director of the Center for Neuroscience and Artificial Intelligence at Baylor, in a release. "For instance, we found that the optimal stimulus for some neurons in the early stages of processing in the neocortex were checkerboards, or sharp corners as opposed to simple edges which is what we would have expected according to the current dogma in the field."

The research is ongoing and will only continue to help dissect how the brain sees and interprets visual elements.

Axiom Space-tested cancer drug advances to clinical trials

mission critical

A cancer-fighting drug tested aboard several Axiom Space missions is moving forward to clinical trials.

Rebecsinib, which targets a cancer cloning and immune evasion gene, ADAR1, has received FDA approval to enter clinical trials under active Investigational New Drug (IND) status, according to a news release. The drug was tested aboard Axiom Mission 2 (Ax-2) and Axiom Mission 3 (Ax-3). It was developed by Aspera Biomedicine, led by Dr. Catriona Jamieson, director of the UC San Diego Sanford Stem Cell Institute (SSCI).

The San Diego-based Aspera team and Houston-based Axiom partnered to allow Rebecsinib to be tested in microgravity. Tumors have been shown to grow more rapidly in microgravity and even mimic how aggressive cancers can develop in patients.

“In terms of tumor growth, we see a doubling in growth of these little mini-tumors in just 10 days,” Jamieson explained in the release.

Rebecsinib took part in the patient-derived tumor organoid testing aboard the International Space Station. Similar testing is planned to continue on Axiom Station, the company's commercial space station that's currently under development.

Additionally, the drug will be tested aboard Ax-4 under its active IND status, which was targeted to launch June 25.

“We anticipate that this monumental mission will inform the expanded development of the first ADAR1 inhibitory cancer stem cell targeting drug for a broad array of cancers," Jamieson added.

According to Axiom, the milestone represents the potential for commercial space collaborations.

“We’re proud to work with Aspera Biomedicines and the UC San Diego Sanford Stem Cell Institute, as together we have achieved a historic milestone, and we’re even more excited for what’s to come,” Tejpaul Bhatia, the new CEO of Axiom Space, said in the release. “This is how we crack the code of the space economy – uniting public and private partners to turn microgravity into a launchpad for breakthroughs.”

Chevron enters the lithium market with major Texas land acquisition

to market

Chevron U.S.A., a subsidiary of Houston-based energy company Chevron, has taken its first big step toward establishing a commercial-scale lithium business.

Chevron acquired leaseholds totaling about 125,000 acres in Northeast Texas and southwest Arkansas from TerraVolta Resources and East Texas Natural Resources. The acreage contains a high amount of lithium, which Chevron plans to extract from brines produced from the subsurface.

Lithium-ion batteries are used in an array of technologies, such as smartwatches, e-bikes, pacemakers, and batteries for electric vehicles, according to Chevron. The International Energy Agency estimates lithium demand could grow more than 400 percent by 2040.

“This acquisition represents a strategic investment to support energy manufacturing and expand U.S.-based critical mineral supplies,” Jeff Gustavson, president of Chevron New Energies, said in a news release. “Establishing domestic and resilient lithium supply chains is essential not only to maintaining U.S. energy leadership but also to meeting the growing demand from customers.”

Rania Yacoub, corporate business development manager at Chevron New Energies, said that amid heightening demand, lithium is “one of the world’s most sought-after natural resources.”

“Chevron is looking to help meet that demand and drive U.S. energy competitiveness by sourcing lithium domestically,” Yacoub said.
