Rice University chemist Bruce Weisman has been awarded the Richard E. Smalley Research Award for his decades of nanocarbon research, according to a statement from the university.

The honor is a full circle moment for Wiseman, as the award is named after Weisman's long-time Rice colleague and friend, Rick Smalley, who Wiseman said helped shape his career.

“It changed my career,” Weisman said in a statement from Rice about his work with Smalley. “Everything I’ve done in the last 20 years has been an outgrowth, a consequence of that.”

Still, Weisman has earned many achievements of his own. He joined Rice's faculty in 1979 as a spectroscopist and first began working with Smalley in 1985 after Smalley's groundbreaking discovery of carbon 60, or buckyballs. The discovery proved that carbon could take on other forms and it won Smalley and his teammates the 1996 Nobel Prize in Chemistry.

Weisman and Smalley then collaborated on experiments to measure the electronic spectra of carbon 60 and carbon 70. In the early 2000s, they published two seminal nanotube studies in Science in which Weisman shared his new faster, simpler and cheaper spectrometric method of assaying nanotubes, according to Rice.

In 2004 Weisman founded a company, Applied NanoFluorescence, to commercialize the technology. The company still exists and continues to research the optical properties of carbon nanotubes.

He is also an elected fellow of the American Physical Society, the American Association for the Advancement of Science and the the Electrochemical Society (ECS) and former chair of the ECS Nanocarbons Division. The ECS will present Weisman with the 2024 Smalley Research Award in May. The award is given every two years to recognize “outstanding achievements in, or scientific contributions to, the science of fullerenes, nanotubes and carbon nanostructures.”

Earlier this month, another Rice professor won a highly competitive award. Assistant professor Amanda Marciel, the William Marsh Rice Trustee Chair of chemical and biomolecular engineering, was granted a National Science Foundation's CAREER Award that comes with $670,406 over five years to continue her research in designing branch elastomers.

The grant will also create opportunities in soft matter research for undergraduates and underrepresented scientists. Click here to learn more.

Meanwhile, another Houston-based chemist was also recently recognized for their work. Baylor College of Medicine's Livia Schiavinato Eberlin was named the 2024 recipient of the Norman Hackerman Award in Chemical Research in December.

The award from the Houston-based Welch Foundation recognizes the accomplishments of chemical scientists in Texas who are early in their careers. Eberlin will be granted $100,000 for this honor.

Two Rice University spinouts, Coflux Purification and DexMat, appear on a new list of the world’s 50 cleantech companies to watch.

Cleantech Group’s 2026 Cleantech 50 to Watch list recognizes early-stage companies “creating groundbreaking solutions to address some of the world’s most pressing environmental and sustainability challenges.”

Cleantech Group, a market research, consulting, and events company, selects the 50 honorees based on insights from analysts and early-stage innovators, along with public nominations.

Destroying “forever chemicals”

Coflux, founded in 2024, offers an onsite treatment system that captures and destroys manufactured “forever chemicals”—per- and polyfluoroalkyl substances—in water and wastewater. It’s a member of Greentown Houston.

Alec Ajnsztajn, CEO; Jeremy Daum, chief technology officer; and Dana Vazquez, chief commercial officer, co-founded Coflux. Ajnsztajn and Daum earned doctoral degrees from Rice, and Vazquez earned an MBA from the university.

Coflux spun out of Rice labs directed by professors Rafael Verduzco and Pulickel Ajayan.

Last year, Coflux received a $175,000 grant from the U.S. Food and Drug Administration’s National Institute of Food and Agriculture. The startup has also raised more than $500,000 in non-dilutive funding, including $80,000 awarded in 2024 by Rice’s One Small Step Grant program.

Promoting an alternative to copper

DexMat, founded in 2015, produces carbon nanotube products such as fibers, yarns, cables, and fabric. The company’s products address demand for materials that can reduce carbon emissions, according to CB Insights.

Its main product, Galvorn, is a copper alternative made of carbon nanotube fibers. CB Insights says Galvorn is engineered to be lighter and stronger than traditional conductive materials like carbon and steel. It’s used in industries such as energy, aerospace, defense, automotive, consumer electronics, and health care.

DexMat emerged from Matteo Pasquali’s Carbon Lab at Rice. Pasquali, co-founder of DexMat, co-invented the company’s technology with the late Nobel Prize-winning chemist Rick Smalley. Smalley was a professor of chemistry, physics, and astronomy at Rice.

Pasquali is a professor of chemical and biomolecular engineering, chemistry, materials science, and nanoengineering at Rice. He co-founded DexMat with Rice graduate Dmitri Tsentalovich, the company’s director of product innovation.

Earlier this year, DexMat raised $5 million in seed funding from Non Sibi Ventures, Governance Partners, Tailwind Futures, BetterWay, Capital Factory, and other investors. The company also secured $3 million in non-dilutive funding.

In 2023, DexMat raised $3 million in a pre-seed round led by Shell Ventures.
