making better masks

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."

Building Houston

Call it the Bayou City Blues. A report from job website Lensa ranks Houston third among the U.S. cities with the unhappiest workers.

The report looks at four factors — vacation days taken, hours worked per week, average pay, and overall happiness — to determine the happiest and unhappiest cities for U.S. workers.

Lensa examined data for 30 major cities, including Dallas and San Antonio. Dallas appears at the top of the list of the cities with the unhappiest workers, and San Antonio lands at No. 8.

Minneapolis ranks first among the cities with the happiest workers.

Here's how Houston fared in the four ranking categories:

  • 16.6 million unused vacation days per year.
  • 40.1 average hours worked per week.
  • Median annual pay of $32,251.
  • Happiness score of out of 50.83.

Dallas had 19.4 million unused vacation days per year, 40.5 average hours worked per week, median annual pay of $34,479, and a happiness score of 53.3 out of 100.

Meanwhile, San Antonio had 5.7 million unused vacation days per year, 39.2 average hours worked per week, median annual pay of $25,894, and a happiness score of 48.61.

Texas tops Lensa's list of the states with the unhappiest workers.

"While the Lone Star State had a decent happiness score of 52.56 out of 100, it scored poorly on each of the other factors, with Texans allowing an incredible 67.1 million earned vacation days go to waste over the course of a year," Lensa says.

In terms of general happiness, Houston shows up at No. 123 on WalletHub's most recent list of the happiest U.S. cities. Dallas takes the No. 104 spot, and San Antonio lands at No. 141. Fremont, California, grabs the No. 1 ranking.
