Collaborators from two Houston universities are leading the way in engineering a biomaterial into a scalable, multifunctional material that could potentially replace plastic.

The research was led by Muhammad Maksud Rahman, an assistant professor of mechanical and aerospace engineering at the University of Houston and an adjunct assistant professor of materials science and nanoengineering at Rice University. The team shared its findings in a study in the journal Nature Communications earlier this month. M.A.S.R. Saadi, a doctoral student in material science and nanoengineering at Rice, served as the first author.

The study introduced a biosynthesis technique that aligns bacterial cellulose fibers in real-time, which resulted in robust biopolymer sheets with “exceptional mechanical properties,” according to the researchers.

Biomaterials typically have weaker mechanical properties than their synthetic counterparts. However, the team was able to develop sheets of material with similar strengths to some metals and glasses. And still, the material was foldable and fully biodegradable.

To achieve this, the team developed a rotational bioreactor and utilized fluid motion to guide the bacteria fibers into a consistent alignment, rather than allowing them to align randomly, as they would in nature.

The process also allowed the team to easily integrate nanoscale additives—like graphene, carbon nanotubes and boron nitride—making the sheets stronger and improving the thermal properties.

“This dynamic biosynthesis approach enables the creation of stronger materials with greater functionality,” Saadi said in a release. “The method allows for the easy integration of various nanoscale additives directly into the bacterial cellulose, making it possible to customize material properties for specific applications.”

Ultimately, the scientists at UH and Rice hope this discovery could be used for the “next disposable water bottle,” which would be made by biodegradable biopolymers in bacterial cellulose, an abundant resource on Earth.

Additionally, the team sees applications for the materials in the packaging, breathable textiles, electronics, food and energy sectors.

“We envision these strong, multifunctional and eco-friendly bacterial cellulose sheets becoming ubiquitous, replacing plastics in various industries and helping mitigate environmental damage,” Rahman said the release.

Chevron names inaugural cohort of Houston energy innovators

research ready

Anew program from Rice University and Chevron has named its inaugural cohort.

Funded by Chevron, the Chevron Energy Graduate Fellowship will provide $10,000 each to 10 Rice graduate students for the current academic year, which supports research in energy-related fields.

The Rice Sustainability Institute (RSI) hosted the event to introduce the inaugural cohort of the Rice Chevron Energy Graduate Fellowship at the Ralph S. O’Connor Building for Engineering and Science. Director of the RSI and the W. Maurice Ewing Professor in Earth, Environmental and Planetary Sciences, Carrie Masiello presented each fellow with a certificate during the ceremony.

“This fellowship supports students working on a wide range of topics related to scalable innovations in energy production that will lead to the reduction of carbon dioxide emissions,” Masiello says in a news release. “It’s important that we recognize the importance of intellectual diversity to the kind of problem-solving we have to do as we accomplish the energy transition.”

The work of the students focuses on creating "real-world, scalable solutions to transform the energy landscape,” per the Rice release. Recipients of the fellowship will research solutions to energy challenges that include producing eco-friendly hydrogen alternatives to fossil fuels and recycling lithium-ion batteries.

Some of the fellows' work will focus on renewable fuels and carbon-capture technologies, biological systems to sequester carbon dioxide, and the potential of soil organic carbon sequestration on agricultural land if we remove the additionality constraint. Xi Chen, a doctoral student in materials science and nanoengineering, will use microwave-assisted techniques to recycle lithium-ion batteries sustainably.

Rice President Reginald DesRoches began the event by stressing the importance of collaboration. Ramamoorthy Ramesh, executive vice president for research at Rice, echoed that statement appearing via Zoom to applaud the efforts of doing what is right for the planet and having a partner in Chevron.

“I’m excited to support emerging leaders like you all in this room, who are focused on scalable, innovative solutions because the world needs them,” Chris Powers, vice president of carbon capture, utilization and storage and emerging at Chevron New Energies and a Rice alum, says at the event. “Innovation and collaboration across sectors and borders will be key to unlocking the full potential of lower carbon energies, and it’s groups like you, our newest Chevron Fellows, that can help move the needle when it comes to translating, or evolving, the energy landscape for the future.”

Houston scientists discover breakthrough process for lithium-ion battery recycling

future of EVs

With the rise of electric vehicles, every ounce of lithium in lithium-ion batteries is precious. A team of scientists from Rice University has figured out a way to retrieve as much as 50 percent of the material in used battery cathodes in as little as 30 seconds.

Researchers at Rice University’s Nanomaterials Laboratory led by Department of Materials Science and NanoEngineering Chair Pulickel Ajayan released the findings a new study published in Advanced Functional Materials. Their work shows that the process overcomes a “bottleneck” in lithium-ion battery recycling technology. The researchers described a “rapid, efficient and environmentally friendly method for selective lithium recovery using microwave radiation and a readily biodegradable solvent,” according to a news release.

Past recycling methods have involved harsh acids, and alternative eco-friendly solvents like deep eutectic solvents (DESs) at times have not been as efficient and economically viable. Current recycling methods recover less than 5 percent of lithium, which is due to contamination and loss during the process.

In order to leach other metals like cobalt or nickel, both the choline chloride and the ethylene glycol have to be involved in the process, according to the researchers at Rice. The researchers submerged the battery waste material in the solvent and blasted it with microwave radiation since they knew that of the two substances only choline chloride is good at absorbing microwaves.

Microwave-assisted heating can achieve similar efficiencies like traditional oil bath heating almost 100 times faster. Using the microwave-based process, Rice found that it took 15 minutes to leach 87 percent of the lithium, which differs from the 12 hours needed to obtain the same recovery rate via oil bath heating.

“This method not only enhances the recovery rate but also minimizes environmental impact, which makes it a promising step toward deploying DES-based recycling systems at scale for selective metal recovery,” Ajayan says in the release.

Due to rise in EV production, the lithium-ion battery global market is expected to grow by over 23 percent in the next eight years, and was previously valued at over $65 billion in 2023.

“We’ve seen a colossal growth in LIB use in recent years, which inevitably raises concerns as to the availability of critical metals like lithium, cobalt and nickel that are used in the cathodes,” the study's co-author, Sohini Bhattacharyya, adds. “It’s therefore really important to recycle spent LIBs to recover these metals.”

Houston material science company strategically rolls out flagship product nationwide

houston innovators podcast episode 174

A Houston startup is celebrating its nationwide launch of its flagship product that coats roofs to reduce energy waste.

NanoTech's Nano Shield Cool Roof Coat is a unique product that can be added onto roofs to reduce energy waste on buildings. Co-founder and CEO Mike Francis and Chief Commercial Officer Carrie Horazeck joined the Houston Innovators Podcast to share more details about the product.

"It's just a coating that can go on top of existing structure — any type of commercial roof," Horazeck says on the show. "We have a pretty good amount of data from 2022 showcasing that we can reduce HVAC consumption within the building by about 30 to 40 percent.

"Our clients really see a immediate benefit in their energy bill, and, of course, if you reduce the HVAC consumption, that automatically translates to a decrease in your scope one emissions," she continues.

Now, NanoTech is playing in the climatetech materials space, the duo explains, and is able to offer clients the opportunity of sustainability with a return — and provide the data for them to prove it.

When deciding how to roll out the product nationally, Francis and Horazeck decided to create a partner enablement program of around 20 companies rather than going with one big distributor.

"We wanted to make sure we developed really strong relationships with our partners and brought on partners that really believed in our vision and understood what we're trying to do at NanoTech — not just with the roof coating, but the whole vision of our company," Horazecks says, explaining that NanoTech has 12 partner companies already and is actively interviewing for the last eight spots.

The roof coating is just the beginning, Francis and Horazeck say about the growing company. NanoTech, which also has a fireproofing product that can protect against fires of up to 1,800 degree Celcius temperatures, also is working on a clear coating product for windows and even solar panels.

"We have the technologies — we're filing multiple patents almost every month to enter different areas of the green building and fireproofing spaces. We're working with more than 40 Fortune 500 companies — things are really clicking," Francis says on the show. "What I think is the next period in our company history is hiring the best talent we can possibly find."

Francis and Horazeck share more about the future of NanoTech on the podcast, and each share their thoughts on the vast opportunities in Houston's networking community and innovation ecosystem. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

UTHealth Houston team joins NASA initiative to protect border drinking water

water watch

Climate change means far more to public health than living with hotter days. Transformations in our weather are contributing to challenges in accessing safe drinking water in some communities.

One of the most dire situations is along the US–Mexico border. The National Aeronautics and Space Administration (NASA) is seeking to address that issue with its Water Quality Applications program. An 11-researcher project led by a UTHealth Houston School of Public Health faculty member has been selected to participate.

“Drinking water is one of the most fundamental public health protections, but producing safe drinking water involves a delicate balance,” Yun Hang, assistant professor of environmental and occupational health sciences, said in a news release. Her team’s proposal was one of 93 that were submitted for funding through NASA’s Research Opportunities in Space and Earth Sciences (ROSES)-2025 program.

This is the first time that NASA has worked with a team devoted to water quality applications. The group, which includes researchers from across the nation, will use satellite observations of Earth, as well as hydrologic modeling, to potentially anticipate and act on water quality conditions as they change. Challenges addressed over the course of the three-year program, which kicked off in June, might include problems with water quality due to climate variability and increased pressure on water resources.

Hang’s team will focus on a pair of borderlands: Paso del Norte and the Rio Grande Valley.

“Working closely with El Paso Water ensures that our research addresses real operational needs while helping utilities better prepare for climate-related water quality changes and continue providing safe drinking water to communities across the Texas border region,” Hang added in the release.

She and the team will use data gathered by NASA on both past and future Earth-observing missions, which will allow them to track environmental changes that may affect source water quality. Combined with past water treatment records and hydrologic models, the team will also utilize artificial intelligence to develop predictive tools that aim to stop issues before they become larger hurdles to water safety.

Another one of the project’s goals is to create visualization tools and source water summaries that can be utilized by those without scientific expertise. The tools will be produced in English and Spanish to further broaden their accessibility.

The hope is that the materials made by the team will also go far beyond the border, with protocols that can be adapted or adopted by other areas dealing with water quality issues.

Houston helps power Texas’ rise as AI infrastructure hub, new report finds

eyes on ai

Houston plays a major role in Texas’ rapidly evolving AI economy, a new report indicates.

The report from Build American AI, a pro-AI advocacy group, notes Houston’s growing AI presence includes:

A factory being built by AI chipmaker NVIDIA and electronics manufacturer Foxconn that will produce AI supercomputers and infrastructure systems
Houston Methodist’s use of ambient AI to listen to health care providers’ conversations with patients, eliminating the need for manual notetaking
An abundance of AI products and services for the energy sector

Across the state, billions of dollars in new AI investments are fueling advancements in construction, manufacturing, energy production, logistics, and health care, according to the report.

“Texas is not merely a place where AI products will be used. Texas is becoming one of the places where the AI economy is being assembled,” the report says.

Particularly noteworthy are four major AI-related projects around the state representing an investment of more than $140 billion, including Google’s $40 billion buildout of AI data centers.

“While California had a headstart in building the software era, Texas will build the infrastructure era,” says the report. “That is not a slogan. Economic research has revealed for decades that innovation happens where the local conditions make building and collaboration possible, and Texas is positioned to be a central hub.”

According to the report, components of Texas’ infrastructure era include:

Energy leadership
Top-tier hospitals
Semiconductor investments
Construction capabilities
Data center growth
Major companies and universities

On the workforce front, Stanford University’s 2026 AI Index found Texas had 80,547 AI job postings in 2025, accounting for 8 percent of the national total.

“Texas no longer needs to ask whether AI will reshape the economy. It already has,” the report concludes. “The question is whether Texas will merely host part of that future or lead it.”
