Physics professor at University of Houston puts nanotech to work to fight the spread of COVID-19

The start of 2020, though most didn't know it at the time, meant a huge change to society. Though coronavirus didn't yet seem to be an issue for the United States, the world was entering into a new normal where wearing face masks in public is common and necessary to prevent the spread of COVID-19.

"We left normal in December," says Seamus Curran, a professor of physics at the University of Houston, "and, when everyone was planning their New Year's resolutions, little did we know that the old normal of before is gone. None of us saw that life passing away — and it was taken away by a bug 1,000 times smaller than lice. And like lice, it's going to be with us for a long time."

To that end, Curran, who is well-known for his work commercializing nanotechnologies, is pulling from his past to deal with a future demand. The professor is using a hydrophobic coating he developed nearly 10 years ago to improve the ability of surgical masks to protect against transmission of the virus.

It's no secret that good face masks are a dire, worldwide need. But Curran notes that standard masks are "somewhat porous, and especially if they get wet, they can allow the virus to penetrate." People infected with the virus, he adds, could spread it even through a mask, while people who aren't sick could still become infected, despite wearing a less-protective mask.

Curran calls N95 masks, "the gold standard, able to filter very small particles and offering better protection than standard surgical masks." But he notes that they are hard to manufacture, and global demand is for tens of millions of items. His work will make masks impervious to water, thus improving protection, he explains.

That means those who already own masks are in luck: Curran's team is planning to sell spray for the hydrophobic coatings so that people can apply it themselves at home or at work. "However, it's cheaper and far more effective to be able to apply it in large batch quantities that manufacturers can do," Curran adds.

The globally minded Curran has only one local requirement: "We will only sell to U.S. manufacturers that manufacture here in the U.S. It's not a limiting factor and may change in the future, but right now, I have to deal with my community here in Houston, Texas, and the U.S. It has to be my priority."

Curran and his team are working though the process to make sure their coatings are compliant with all federal rules. "Sometimes, this is making sure your materials are registered and allowed," he says. "Sometimes it's making sure the products follow relevant EPA and FDA guidelines. However, we are very close, as in weeks, and not some arbitrary academic timeline in the distant future."

He first launched a nanotechnology business in 2013, according to UH. His company, Integricote, based at the UH Technology Bridge, focuses on manufacturing sealers for masonry, wood, and concrete. The professor has developed nanotech coatings for fabrics since 2011, technology that he now is using to demonstrate a way to provide more protection against SARS and COVID-19.

Curran, who often says he hates to "play defense," hopes to get a jump on the virus spread with his new technology and take a proactive approach to a long-term issue. "Remember, H1N1 affected 61 million Americans and 12,500 people died from it between 2009 and 2010," he notes. "Do we think that's it? Did we think Ike was the last big hurricane to hit us, or do we expect more? Yet, we have compensated for this and found a way to be resilient and have a normal life."

Technical and scientific in his work, the passionate professor says he is galvanized by a simple, primal motive. "This is personal, this virus has threatened my family and I'm not sitting back, ideally, just letting this happen," Curran says. "I'm just like any other husband, father, son, brother, and uncle: I will do all I can to protect those dearest to me and I will not have it any other way."

ExxonMobil gets approval for $5B Texas Gulf Coast carbon capture project

CCS Expansion

Spring-based ExxonMobil has won approval from the Texas Railroad Commission for a $5 billion carbon capture and storage project in East Texas.

Dominic Genetti, senior vice president of CCS at ExxonMobil, told The Financial Times, which broke the news, that the Railroad Commission’s action is a “major milestone” that lets the company keep expanding along the Gulf Coast. In a 2-1 vote, commissioners authorized a carbon sequestration permit for the project.

“The Railroad Commission clearly recognizes the important role carbon capture and storage can play in meeting growing global demand for lower-carbon products while supporting new jobs and economic growth,” Genetti said.

The U.S. Environmental Protection Agency (EPA) approved ExxonMobil’s Rose CCS project last year.

The project will enable the company to inject about 53 metric tons of industrial customers’ carbon emissions into three underground wells it drilled in the Beaumont-Port Arthur area. Over a 13-year period, ExxonMobil plans to inject about 4 million metric tons per year into the Fleming and Upper Frio rock formations, according to Carbon Herald.

ExxonMobil says it owns the world’s first and largest CCS system, comprising 1,300 miles of CO2 pipeline and secure storage sites. Seventy percent of the pipelines are along the Gulf Coast.

The company ramped up its CCS business in 2023 with the $4.9 billion purchase of Denbury, which owned about 1,000 miles of CO2 pipelines.

“Our expertise, combined with Denbury’s talent and CO2 pipeline network, expands our low-carbon leadership and best positions us to meet the decarbonization needs of industrial customers while also reducing emissions in our own operations,” ExxonMobil Chairman and CEO Darren Woods said when the deal closed.

In January, Genetti wrote in a post on ExxonMobil’s website that the company is committed to CCS “for the long haul.”

“CCS is not new technology, but it’s flown relatively under the radar compared with the attention that production of hydrocarbons commands,” he wrote. “Now, as the world becomes more aware of the need to reduce emissions, CCS finally has a brighter spotlight and a broader runway to scale up.”

The company also announced this week that it has begun CCS operations at a direct reduced iron facility in Convent, Louisiana. The project will capture, transport and store up to 800,000 metric tons of CO2 per year, according to the company.

Houston researchers develop breakthrough device that could bypass spinal injuries

breakthrough research

Scientists at Houston Methodist have announced a significant leap forward for spinal cord injury recovery.

The researchers have developed a device that essentially bypasses spinal injuries, allowing signals from previously “lost” functions to reach the brain, a new study published in Nature Communications shows.

“Most current technologies try to improve whatever function remains after a spinal cord injury,” Dr. Damiano Barone, assistant professor of neurosurgery in the Department of Neurosurgery at Houston Methodist and co-lead on the study, said in a news release. “Our goal is different. Rather than fixing the injury itself, we want to bypass it completely and create an alternative route for signals to travel.”

The study involved a single ultrathin circumferential electrode array made to conform around the spinal cord without penetrating neural tissue, which was implanted into rodent and pig models with spinal injuries. The electrode array was able to interpret motor, sensory and autonomic signals around the injury. Think of it as a set of detours that restore road access to isolated towns after a disaster destroys the highway instead of just rebuilding the highway.

Over the course of three days, the arrays detected signals of intended movement from low-frequency spinal oscillations with more than 94 percent accuracy. This worked across species and was replicated in feasibility studies on human cadavers.

This research could serve as a new foundation for neuroprosthetic implants that could restore connectivity to the 2.5 million people worldwide suffering from spinal injuries that result in loss of ability. Future development could result in everything from restored organ function to mobility, according to Houston Methodist.

George Malliaras, the Prince Professor of Technology in the Department of Engineering at the University of Cambridge, who co-led the study, sees it as a fundamental restructuring of the science of spinal trauma.

“This could represent a paradigm change in how we think about spinal cord injuries,” Malliaras said. “Instead of starting from the idea that what is lost is gone forever, this approach asks whether we can restore function by carrying the signal around the injury.”

Further work involving laboratory models will need to be completed before launching human trials.

Grants from the National Institutes of Health, Houston Methodist Katz Investigator Award, Helaers Research Award and the Engineering and Physical Sciences Research Council helped support the study. Other collaborators on the study include Salim Hadwe, Ruben Serrano, George Psaltakis, Margaux Forner, Chaeyeon Lee, Sydney Swedick, Moleca Ghnnam, Tawfique Hasan and Alejandro Carnicer-Lombarte from the University of Cambridge; and Anton Banta and Xueer Zhang from Houston Methodist.

Abbott assembles expert team to help lure U.S. Space Academy to Texas

space race

State Rep. Greg Bonnen of Friendswood has been tapped to lead a new team that will promote Texas as the future home of the U.S. Space Academy.

Bonnen, a neurosurgeon, chairs Houston Physicians’ Hospital and the powerful Texas House Appropriations Committee. His House district is close to NASA’s Johnson Space Center.

Gov. Greg Abbott appointed the seven-member team. Last month, President Trump signed an executive order establishing the Presidential Commission on the U.S. Space Academy. Commission members, who held their first meeting this month, will recommend a permanent location for the academy.

Texas officials are pushing a site near Johnson Space Center to host the academy. Alabama, Colorado and Florida are among Texas’ competitors.

In a joint statement, U.S. Sen. Ted Cruz and U.S. Rep. Brian Babin, both of Texas, issued a statement backing the state’s bid for the academy. Cruz lives in Houston. Babbin lives in Woodville, about 55 miles south of Beaumont.

“America’s space program is built across the country, but Texas is where the pieces come together,” the lawmakers said. “We are ready to lead the next generation of space pioneers and look forward to showing why Texas is the right home for the U.S. Space Academy.”

The academy’s curriculum will include technical education, leadership development and public service components. Graduates will be set up for careers in the U.S. military, civil service, and aerospace sectors.

The Abbott-appointed team will work with the Texas Space Commission to prepare the state’s proposal for the academy.

In addition to Bonnen, team members with ties to Houston include:

  • Robert Ambrose, who grew up in Houston. He worked at Johnson Space Center before becoming associate director of the Texas A&M Space Institute.
  • Former NASA astronaut Nancy Curry-Gregg, director of the Texas A&M Space Institute. She earned a doctoral degree from the University of Houston and previously worked at Johnson Space Center.
  • Former NASA astronaut Jack Fischer, senior vice president of Houston-based Intuitive Machines. The company builds spacecraft, delivers payloads to the moon and launches satellites.

“Texas is the home of America’s human spaceflight program,” Abbott said in a release. “No state can match what Texas brings to this mission.”

“NASA’s Johnson Space Center, world-class universities, a premier commercial space industry, major military installations, and an unmatched aerospace workforce give Texas every asset the United States Space Academy requires,” the governor added.
