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.

Houston launches Google-backed tool to address urban tree cover disparities

seeing green

The oldest national nonprofit conservation organization in the U.S American Forests has launched the Houston Tree Equity Score Analyzer, which was developed through local nonprofit Trees For Houston and local stakeholders from local government, environmental groups and the public health sector, and supported by Google’s philanthropic arm Google.org with a $450,000 grant.

To mark the launch, Trees For Houston and American Forest celebrated the partnership and worked to plant 50 trees at Shadydale Elementary in Northeast Houston on December 6.

“This marks a significant milestone for Houston's urban forestry efforts,” says Texas State Representative Senfronia Thompson at the December 6 event. “This effort goes beyond simply planting trees—it’s about creating the foundation for a greener, more inclusive future for our community. By uniting diverse resources and partners, including American Forests, Google.org and Trees For Houston, we’re showcasing a powerful dedication to enhancing the environmental well-being and quality of life in our urban areas.”

How the analyzer works is it provides auto-generated data on the impact of tree cover alongside demographic data, land use, poverty and other socioeconomic factors to assist with guide planning and investments to grow tree cover. The Houston Tree Equity Analyzer found that Shadydale Elementary has just 9 percent tree canopy coverage, which falls short of the 30 percent canopy goal for the area. The planting will increase the canopy by 6 percent according to a news release. According to American Forests, nearly 80 percent of urban neighborhoods in the United States have inadequate tree cover.

“The Tree Equity Score Analyzer enables communities to take a human-centered, data-driven approach to developing actionable tree planting and protection plans, ensuring they are focusing on areas that need them most, like Shadydale Elementary School,” said Vice President of GIS and Data Science at American Forests Chris David said in a news release.

American Forests is aiming to assist with at least 100 cities to make progress on Tree Equity by 2030. American Forests helped to unlock $1.5 billion, which was the nation’s largest federal investment in urban forestry in the Inflation Reduction Act of 2022.

“We look forward to working with our partners in Houston to continue to grow equitable tree cover in the community with data-driven approaches and action,” David says in a news release.

Researchers from the University of Houston — along with a Hawaiian company — have received $3.3 million in funding to explore artificial intelligence-backed subsurface sensing system for safe and efficient underground power line installation.

Houston's power lines are above ground, but studies show underground power is more reliable. Installing underground power lines is costly and disruptive, but the U.S. Department of Energy, in an effort to find a solution, has put $34 million into its new GOPHURRS program, which stands for Grid Overhaul with Proactive, High-speed Undergrounding for Reliability, Resilience, and Security. The funding has been distributed across 12 projects in 11 states.

“Modernizing our nation’s power grid is essential to building a clean energy future that lowers energy costs for working Americans and strengthens our national security,” U.S. Secretary of Energy Jennifer M. Granholm says in a DOE press release. Continue reading.

This Houston innovator's innovative corrosion detection tech is vital to the future of energy

now streaming

Houston-based Corrolytics approach is to help revolutionize and digitize microbial corrosion detection — both to improves efficiency and operational cost for industrial companies, but also to move the needle on a cleaner future for the energy industry.

"We are having an energy transition — that is a given. As we are bringing new energy, there will be growth of infrastructure to them. Every single path for the energy transition, corrosion will play a primary role as well," Anwar Sadek, co-founder and CEO of Corrolytics, says on the Houston Innovators Podcast.

The technology Sadek and his team have created is a tool to detect microbial corrosion — a major problem for industrial businesses, especially within the energy sector. Sadek describes the product as being similar to a testing hit a patient would use at home or in a clinic setting to decipher their current ailments.



Users of the Corrolytics test kit can input their pipeline sample in the field and receive results via Corrolytics software platform.

"This technology, most importantly, is noninvasive. It does not have to be installed into any pipelines or assets that the company currently has," Sadek explains. "To actually use it, you don't have to introduce new techniques or new processes in the current operations. It's a stand-alone, portable device."

Corrolytics hopes to work with new energies from the beginning to used the data they've collected to prevent corrosion in new facilities. However, the company's technology is already making an impact.

"Every year, there is about 1.2 gigaton of carbon footprint a year that is released into the environment that is associated with replacing corroded steel in general industries," Sadek says. "With Corrolytics, (industrial companies) have the ability to extend the life of their current infrastructure."

Despite having success in taking his technology from lab to commercialization, Sadek made the strategic decision to move his company, Corrolytics, from where it was founded in Ohio to Houston.

"Houston is the energy capital of the world. For the technology we are developing, it is the most strategic move for us to be in this ecosystem and in this city where all the energy companies are, where all the investors in the energy space are — and things are moving really fast in Houston in terms of energy transition and developing the current infrastructure," Sadek says.

And as big as a move as it was, it was worth it, Sadek says.

"It's been only a year that we've been here, but we've made the most developments, the most outreach to clients in this one last year."

Sadek says his move to Houston has already paid off, and he cites one of the company's big wins was at the 2024 Houston Innovation Awards, where Corrolytics won two awards.
