A team of researchers at the University of Houston has made two breakthroughs in addressing climate change and potentially reducing the cost of capturing harmful emissions from power plants.

Led by Professor Mim Rahimi at UH’s Cullen College of Engineering, the team released two significant publications that made significant strides relating to carbon capture processes. The first, published in Nature Communications, introduced a membraneless electrochemical process that cuts energy requirements and costs for amine-based carbon dioxide capture during the acid gas sweetening process. Another, featured on the cover of ES&T Engineering, demonstrated a vanadium redox flow system capable of both capturing carbon and storing renewable energy.

“These publications reflect our group’s commitment to fundamental electrochemical innovation and real-world applicability,” Rahimi said in a news release. “From membraneless systems to scalable flow systems, we’re charting pathways to decarbonize hard-to-abate sectors and support the transition to a low-carbon economy.”

According to the researchers, the “A Membraneless Electrochemically Mediated Amine Regeneration for Carbon Capture” research paper marked the beginning of the team’s first focus. The research examined the replacement of costly ion-exchange membranes with gas diffusion electrodes. They found that the membranes were the most expensive part of the system, and they were also a major cause of performance issues and high maintenance costs.

The researchers achieved more than 90 percent CO2 removal (nearly 50 percent more than traditional approaches) by engineering the gas diffusion electrodes. According to PhD student and co-author of the paper Ahmad Hassan, the capture costs approximately $70 per metric ton of CO2, which is competitive with other innovative scrubbing techniques.

“By removing the membrane and the associated hardware, we’ve streamlined the EMAR workflow and dramatically cut energy use,” Hassan said in the news release. “This opens the door to retrofitting existing industrial exhaust systems with a compact, low-cost carbon capture module.”

The second breakthrough, published by PhD student Mohsen Afshari, displayed a reversible flow battery architecture that absorbs CO2 during charging and releases it upon discharge. The results suggested that the technology could potentially provide carbon removal and grid balancing when used with intermittent renewables, such as solar or wind power.

“Integrating carbon capture directly into a redox flow battery lets us tackle two challenges in one device,” Afshari said in the release. “Our front-cover feature highlights its potential to smooth out renewable generation while sequestering CO2.”

Pharma giant considers Houston for $1B manufacturing campus

in the works

Another pharmaceutical giant is considering Houston’s Generation Park for a manufacturing hub.

According to a recent filing with the Texas Jobs, Energy, Technology and Innovation (JETI) program, Bristol Myers Squibb Co. is considering the northeast Houston management district for a new $1 billion multi-modal pharmaceutical manufacturing campus.

If approved, the campus, known as Project Argonaut, could create 489 jobs in Texas by 2031. Jobs would include operations technicians, engineering roles, administrative and management roles, production specialists, maintenance support, and quality control/assurance. The company predicts annual average wages for these positions to be around $96,000, according to the filing.

The project currently includes the 600,000-square-foot facility, but according to the filing, Bristol Myers Squibb “envisions this site growing in scale and capability well beyond its opening configuration."

The Texas JETI program offers companies temporary school property tax limitations in exchange for major capital investment and job creation. E.R. Squibb & Sons LLC applied for a 10-year tax abatement agreement in the Sheldon Independent School District.

The agreement promises a $ 1 billion investment. Construction would begin in 2027 and wrap in 2029.

“The proposed project reflects [Bristol Myers Squibb Co.’s] enduring commitment to bringing innovative medicines to patients and ensuring the long-term supply reliability they depend on,” the filing says. “The proposed project is purpose-built to support and manufacture medicines spanning multiple therapeutic areas and modalities, positioning the site as a long-term launch and commercial campus for decades to come. These medicines will provide therapies to the [Bristol Myers Squibb Co.’s] patients located in markets both nationally and internationally.”

The Fortune 100 company is considering 16 other cities for the new manufacturing facility in the Central and Eastern markets in the U.S. According to the Houston Chronicle, Bristol Myers Squibb Co is still in the “evaluation process” for its potential manufacturing site.

Last fall, Eli Lilly and Co. selected Generation Park for its $6.5 billion manufacturing plant. More than 300 locations in the U.S. competed for the factory. Read more here.

Houston health tech co. lands NIH grant for AI cancer prediction tool

fresh funding

Houston-based CellChorus and Stanford Medicine were recently awarded a Phase I Small Business Innovation Research grant for the company's AI platform to test how certain cancer patients will respond to therapies.

The funding comes from the National Cancer Institute of the National Institutes of Health. According to a filing, the grant totaled just under $400,000.

CellChorus, which spun out from the University of Houston’s Technology Bridge, has developed TIMING (Time-lapse Imaging Microscopy In Nanowell Grids), which analyzes the behavior of thousands of individual immune cells over time and can identify early indicators of treatment success or failure.

The company will work with Stanford's Dr. David Miklos and Dr. Saurabh Dahiya, who have built the Bone Marrow Transplantation and Cell Therapy Biobank. The biobank manages and stores biological samples from patients treated at their clinic and in clinical trials.

"Predicting which patients will achieve durable responses after CAR-T therapy remains one of the most important challenges in the field,” Miklos said in a news release. “We aim to uncover functional cellular signatures that can guide treatment decisions and improve patient outcomes.”

The project will specifically profile cells from patients with relapsed/refractory large B-cell lymphoma (r/rLBCL). According to CellChorus, only about half of r/rLBCL patients who receive CAR-T therapy "achieve a durable, long-term remission." Others do not respond to therapy or experience relapse.

“The sooner we know whether a cancer therapy is working, the better. To maximize patient benefit, we need technology that can provide a robust and early prediction of response to therapy. The technology needs to be scalable, cost-efficient, and capable of rapid turnaround times,” Rebecca Berdeaux, chief scientific officer of CellChorus, added in the release. “We are excited to work with Drs. David Miklos and Saurabh Dahiya and their colleagues on this very important project.”

CellChorus has previously received SBIR grants from federal agencies, including a $2.5 million award in 2024 from its National Center for Advancing Translational Sciences (NCATS) and a $2.3 million SBIR Fast-Track award from the National Institute of General Medical Sciences in 2023.

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.
