Researchers at the University of Houston have unlocked a new way to use crystals to safely dispose of radioactive waste.

The team of UH researchers published a paper in Cell Reports Physical Science this month detailing their discovery of how to use molecular crystals to capture large quantities of iodine, one of the most common products of radioactive fission, which is used to create nuclear energy.

According to a statement from UH, these molecular crystals are based on cyclotetrabenzil hydrazones. Ognjen Miljanic, professor of chemistry and author of the paper, and his team have created the organic molecules containing only carbon, hydrogen and oxygen atoms, which create ring-like crystals with eight smaller offshoots, earning them the nickname "The Octopus."

The discovery was made by Alexandra Robles, the first author of the study and a former doctoral student in Miljanic’s lab.

The crystals have an uptake capacity similar to that of porous metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), which traditionally have been considered the “pinnacle of iodine capture materials," according to UH. They allow iodine to be moved from one area to another, are reusable and can be produced using commercially available chemicals for about $1 per gram in an academic lab.

“They are quite easy to make and can be produced at a large scale from relatively inexpensive materials without any special protective atmosphere,” Miljanic said in a statement.

The team also believes the crystals can be used to capture additional elements like carbon dioxide.

“This is a type of simple molecule that can do all sorts of different things depending on how we integrate it with the rest of any given system,” Miljanic continued. “So, we’re pursuing all those applications as well.”

Next up, Miljanic is looking to find a partner that will help the team explore practical applications and commercial aspects.

UH has been making net-zero news lately. A team of students from UH placed in the top three teams in a national competition for the Department of Energy earlier this summer. The college also shared details about its forthcoming innovation hub, which will house UH's Energy Transition Institute, as well as other centers and programs.

Joseph Powell, founding director of UH's Energy Transition Institute, sat down with EnergyCapitalHTX last week to talk about UH's vision for the organization.

Pipeline robotics: How this Houston startup is revolutionizing corrosion monitoring

listen now

After working for years in the downstream energy industry where safety and efficiency were top priorities, Dianna Liu thought there was a way technology could make a huge difference.

Despite loving her company and her job, she took a leap of faith to start a robotics company to create technology to more safely and efficiently monitor corrosion in pipelines. ARIX Technologies has developed software and hardware solutions for its customers with pipelines in downstream and beyond.

"Overall, this industry is an industry that really harps on doing things safely, doing things well, and having all the data to make really informed decisions," Liu says on the Houston Innovators Podcast. "Because these are huge companies with huge problems, it takes a lot of time to set up the right systems, adopt new things, and make changes."

But it's an industry Liu knows well, so she founded ARIX in 2017 and created a team of engineers to create the first iteration of the ARIX robot, which was at first made of wood, she says. Now, years later, the much-evolved robot moves up and down the exterior of the pipe, using its technology to scan the interior to evaluate corrosion. The technology works with ARIX's software to provide key data analysis.

With customers across the country and the world, ARIX has a strong foothold in downstream, but has garnered interest from other verticals as well — even working with NASA at one point, Liu says.

"Staying in downstream would be nice and safe for us, but we've been very lucky and have had customers in midstream, upstream, and even outside oil and gas and chemicals," she says. "We've gotten inquiries ranging from cosmetics plants to water or wastewater — essentially anything that's round or a pipe that can corrode, we can help with."

Liu, who goes into detail on the show about how critical establishing a positive company culture has been for ARIX, shares a bit about what it's been like growing her company in Houston.

"Houston being the Energy Capital of the World opens a lot of doors to both customers, investors, and employees in a way that's unparalleled. It is a great place to build a company because of that — you have all this expertise in this city and the surrounding areas that's hard to find elsewhere," she says. "Being such a hub — not only for energy, but in terms transportation — means it's easy for us to get to our customers from around the world."
