A nanotechnology developed at the University of Houston is about to make a big difference right on campus.

UH's Facilities/Construction Management Preventive Maintenance team is working on a project that will install air filters that are nanocoated with a material that was first developed at the UH Technology Bridge. UH Professor of Physics Seamus Curran has an extensive background in nanotech, and, as he learned more about COVID-19 and how it spreads, he started nano-coating facemasks to make them more resistant to the small particles that enable the spread of the virus.

Originally developed for the construction business, Curran's coating material could also be used to create hydrophobic facemasks, Curran discovered, and he founded a spin off company, Curran Biotech, to develop his next pandemic-proof innovation: nano-coated air filters.

"The big thing for me when we were shut down was that people couldn't go to work or school. The country can't live that way — but you can't send people back to work in a world that's not safe," Curran said last October in an interview for the Houston Innovators Podcast. "How do you create a safer environment? That's the thing that really got me going in the beginning in the summer. We looked at filters."

Listen to Professor Curran on the Houston Innovators Podcast:

Curran, who says he's learned more about air filters than he ever cared to, realized that even the most expensive air filters can only protect from 10 to 25 percent of viruses. And most buildings' HVAC systems would have to be replaced completely to allow for these pricier, more protective filters. But Curran Biotech's Capture Coating can be used on existing filters and HVAC systems.

Air filters coated with Curran Biotech's sealant were then tested at the New York Family Court Building, by DCAS-Energy Management Division, and now, ahead of the fall semester, UH is implementing the innovation in all buildings that have less than MERV-13 rated filters.

HOUSTON INNOVATORS PODCAST EPISODE 52

For over a decade, Seamus Curran, a physics professor at the University of Houston, has worked on his nanotechnology coating substance. He first thought the innovation could be used on fabrics and textile coating, but he realized, once getting acquainted with the industry, he realized there wasn't an interest for a hydrophobic coating that could be used to prevent the spread of germs — at least, not yet.

"Like anything small startup company, one of the things you have to learn is you have to pivot — or you will die," says Curran, who had created his company Integricote (neé C-Voltaics) to take his innovation to market.

So pivot is what he did. Integricote now markets toward coating and sealing materials within the construction industry — wood, concrete, etc. — to protect from water damage and rotting. As Curran shares on this week's episode of the Houston Innovators Podcast, business was growing steadily. That is until COVID-19 hit.

His construction coating business slowed, much like the rest of business across the country, and classes at UH switched to online. Curran used this newfound time at home to dig deeper into the details of the virus, when an idea hit him.

"I learned the virus traveled in a wet medium," Curran says, "(our coating) is hydrophobic, meaning we can stop it from penetrating any fabrics."

Curran worked to create hydrophobic facemasks using his sealant, and the technology was lauded and covered by various news organizations. He created a new company under Integricote, called Curran Biotech, and he started thinking of the next pandemic-proof innovation he could create using his sealant.

"The big thing for me when we were shut down was that people couldn't go to work or school. The country can't live that way — but you can't send people back to work in a world that's not safe," Curran says. "How do you create a safer environment? That's the thing that really got me going in the beginning in the summer. We looked at filters."

Curran, learning more about air filters than he ever cared to, realized that even the most expensive air filters can only protect from 10 to 25 percent of viruses. And most buildings' HVAC systems would have to be replaced completely to allow for these pricier, more protective filters.

"So, you'd have to replace your equipment and your filter prices go up — and you're still not blocking the virus," Curran says.

Curran Biotech's solution is a spray coating that can be used on air filters to make them more protected from COVID-19 spread.

Curran shared more about his nanotechnology innovation — as well as his excitement for being named one of MassChallenge Texas's finalist within the 2020 Houston cohort — in the episode of the podcast.

Houston biotech VC firm's portfolio cos. score $5.3M in federal funding

money moves

Three portfolio companies of Houston venture capital firm First Bight Ventures have received a combined $5.25 million from the U.S. Defense Department’s Distributed Bioindustrial Manufacturing Program.

“The allocation of funds by the federal government will be critical in helping grow biomanufacturing capacity,” Veronica Breckenridge (née Wu), founder of First Bight, says in a news release. “We are very proud to represent three dynamic companies that are awardees of this competitive and widely praised program.”

The three companies that were awarded Defense Department funds are:

  • Hayward, California-based Visolis, received $2.25 million to plan a facility for production of a chemical that can be transformed into rocket propellants, explosive binders, and sustainable aviation fuel.
  • Alameda, California-based Industrial Microbes received $1.55 million to plan a facility for converting ethanol feedstock into acrylic acid. This acid is a key component used in coatings, adhesives, sealants, lubricants, corrosion inhibitors, and wound dressings.
  • San Diego-based Algenesis received $1.5 million to plan and develop a facility that’ll produce diisocyanates, which are chemical building blocks used to make polyurethane products.

“This award is a testament to our commitment to advancing sustainable materials and will enable us to contribute to both national security and industrial resilience. Our planned facility represents a key step towards securing a domestic supply of critical components for polyurethanes,” says Stephen Mayfield, CEO of Algenesis.

Texas grocer H-E-B finally rolls out digital tap-to-pay services

hi, tech

Texas' favorite grocery store has some good news for shoppers who have a habit of forgetting their wallets. H-E-B is starting a phased rollout for digital tap-to-pay services, starting in San Antonio before spreading to the rest of the chain's stores.

The rollout began Monday, October 7. A release says it'll take "about a week" to spread to all stores in the region before making it ways across Texas. Although it is not known which stores will add the service on what date, the rollout includes all H-E-B stores, including Mi Tienda, H-E-B's Mexican grocery store that has locations in Houston.

With tap to pay, shoppers will finally be able to use smartphone-based systems such as Apple Pay, Samsung Pay, and Google Pay, as well as tapping a physical card.

Payments can be made with those apps, or "digital wallets," at cash registers and self-checkout lanes, as well as restaurants and pharmacies within H-E-B stores. They won't be accepted right away at H-E-B fuel pumps, but customers can use them to pay for gas if they bring their phones to the fuel station payment window.

This isn't exactly cutting-edge technology; Google Wallet launched in 2011, leading the market, and was followed by Apple Pay in 2014. But it's not ubiquitous either. In 2023, a poll by Forbes Advisor found that barely more than half of respondents used digital wallets more than traditional forms of payment.

H-E-B is on a bit of a payment revolutionizing kick, also launching a debit card in 2022 and a partnership in August of 2024 with the H-E-B-owned delivery service Favor for its fastest order fulfillment yet. Central Market and Joe V’s Smart Shop, two other H-E-B brands, also recently launched tap to pay.

“At H-E-B, we’re always exploring a broad range of technologies to enhance how customers shop and pay for products,” H-E-B vice president Ashwin Nathan said in a statement. “This has been one of the most requested services we have received from our customers and partners, and we are excited to now make this popular technology available at all our H-E-B locations.”
