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.

University of Houston collaborates with county on future-facing sustainability efforts

dream team

Researchers at the University of Houston are partnering with the Harris County Office of County Administration’s Sustainability Office, the Harris County Energy Management Team, and other county staff in an effort to develop a comprehensive baseline of energy use and energy-use intensity that will aim to reduce energy costs and emissions in county facilities.

Once fully established, the team will work on tracking progress and evaluating the effectiveness of energy-saving measures over time. They will begin to build the foundation for future programs aimed at maximizing savings, reducing energy consumption, and increasing the use of renewable energy sources in county operations.

Harris County energy managers, Glen Rhoden and Yas Ahmadi, will work with UH professionals, including:

  • Jian Shi, UH Cullen College of Engineering associate professor of engineering technology and electrical and computer engineering
  • Zhu Han, Moores professor of electrical and computer engineering
  • Xidan "Delia" Zhang, UH research intern

The group began collaborating a year ago, and analyzed energy consumption data from county facilities.They were able to successfully identify key summertime energy-saving opportunities and completed retro-commissioning of four county buildings. Those efforts saved over $230,000 annually in electricity costs.

“This project is a prime example of how impactful research at UH can be when applied to real-world challenges, delivering tangible benefits to both the environment and the communities we serve,” Shi says in a news release.

The team will plan to do additional building projects, which includes the development of solar energy and heat pump initiatives, building automation system upgrades, and LED lighting installations. The goal is to reduce electricity usage by at least 5 percent per year for county facilities by 2030 and cut greenhouse gas emissions by 50 percent over the next 5 years for county buildings.

“Addressing climate change and the energy transition requires a collaborative effort that is not only data-driven and action-oriented but also human-centric,” Shi adds. “It’s about more than just technology—it’s about improving the quality of life for Texans.”

Houston-based autonomous trucking tech co. raises $20M

fresh funding

A Houston-based autonomous vehicle technology company has raised early funding.

Bot Auto has announced the completion of its pre-series A funding round which was oversubscribed and raised $20 million. The round was led by investments from Brightway Future Capital, Cherubic Ventures, EnvisionX Capital, First Star Ventures, Linear Capital, M31 Capital, Taihill Venture, Uphonest Capital, and Welight Capital.

“As true believers in autonomous trucking, we're thankful for our investors' shared vision,” Xiaodi Hou, founder and CEO of Bot Auto, says in a news release. “Our strong commitment, combined with recent AI advancements and a sharpened focus on operational efficiency, has created a clear path to commercialization.”

The funds raised will be focused on developing the technology and will opt to avoid unnecessary hiring ahead of operational maturity, scaling the operational footprint prior to product readiness, over expansion and partnership debt. The company aims for a more sustainable and efficient future, and is hoping its engineers and AV executives help Bot Auto become an autonomous trucking game changer.

The Investment is expected to help expand Bot Auto's tech development in autonomous trucking that will focus on safety and operation efficiency.

“Our prospects for success have never been more promising,” Hou adds. “ We march forward, committed to bringing this transformative technology to humanity for a brighter future.”

Bot Auto’s vision aligns with the pioneering spirit of Houston’s legacy in space exploration, striving to achieve remarkable feats in technology and transportation. The company is dedicated to leveraging this investment to make significant strides in the US autonomous trucking industry, ultimately contributing to a more sustainable and efficient future.

Texas-based Tesla posts first quarterly increase in deliveries, but shares slump

mixed feelings

Low interest financing, sweet lease deals, price cuts and free charging boosted Tesla’s global deliveries in the third quarter, the first increase this year for the electric vehicle maker.

The Austin, Texas, company said Wednesday that it delivered 462,890 vehicles from July through September, bolstered by loans as low as 1.99%, and $299 monthly leases on the Model 3, its least expensive vehicle. It delivered 435,059 vehicles during the same period last year.

The figures for July through September came in slightly higher than analyst estimates of 462,000 for the period, according to data provider FactSet.

However, shares of Tesla Inc. dropped sharply in morning trading, down nearly 4%.

The deliveries were “good and a step in the right direction,” wrote Dan Ives of Wedbush, but that there would be pressure on the company's stock because investors had been hoping for even better.

“Overall, this is a clear improvement from the first half and we believe getting in the range of 1.8 million for the year is still the key and important bogey,” Ives said.

Tesla has struggled much of the year to sell its aging model lineup as growth in electric vehicle sales in the U.S. and Europe slowed due to concerns with range, price and the ability to charge on trips.

Falling sales early in the year led to once-unheard of discounts for the automaker, cutting into its industry leading profit margins. Analysts estimated that Tesla’s average vehicle sales price was $42,500 for the third quarter, the lowest price in four years.

The sales decline likely will pull down third quarter earnings when they are announced on Oct. 23.

Tesla’s sales decline comes as competition is increasing from legacy and startup automakers, which are trying to nibble away at the company’s market share.

Nearly all of Tesla’s sales came from the smaller and less-expensive Models 3 and Y, with the company selling only 22,915 of its more expensive models that include X and S, as well as the new Cybertruck.

Wedbush analyst Dan Ives wrote in a note to investors Tuesday that third-quarter sales would bring a rebound as China sales continue to increase and price and demand stabilizes.” As China continues to heat up on the demand story for Tesla with favorable leasing/financing terms and pent-up demand in the region, we are confident that we will see a significant growth figure in the region,” he wrote.

Europe will continue to be slow with macroeconomic pressures, and U.S. demand should stabilize, Ives wrote.

But BNP Paribas Exane said in an investor note that long term expectations of the market are somewhat high for Tesla. The company said its sales estimates for 2026 and 2027 “remain 10% to 15% below the street, respectively.”

Tesla is scheduled to unveil a purpose built robotaxi at an event next week.
