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.

Texas is the 7th hardest working state in America for 2026, says report

Labor Day Report

Texans pride themselves on being industrious, and a new report has confirmed Texas as one of the 10 most hardworking states in America in 2026.

The Lone Star State claimed the No. 7 spot this year in a slight dip from its 2025 ranking, where it appeared in the top five. Texas last ranked 7th in 2024, but the state has consistently appeared among the top 10 for nearly a decade.

WalletHub determined the rankings after analyzing 10 "direct" and "indirect" work factors across all 50 states, and then graded each metric on a 100-point scale, where a score of 100 signified the "hardest working." Analysts then examined each state’s weighted average across all metrics to calculate its overall score and used the resulting scores to rank-order the states.

There was only a 10.32-point difference between Texas and South Dakota, who claimed the top spot as America's hardest working state in 2026 with a score of 64.59 out of a possible 100 points.

Texas ranked 6th nationally in the "direct" work factors category, which examined the following six metrics:

The state's average workweek hours.
Employment rates.
The share of households where no adults work.
The share of workers leaving vacation time unused.
The share of "engaged" workers — those that are "involved in, enthusiastic about, and committed to their work and workplace," as defined by Gallup.
The rate of "idle youth" — individuals aged 18-24 who are not currently enrolled in school, not working, and have no degree beyond a high school diploma or GED.

Texas ties with Louisiana for the second highest average workweek hours nationwide, with Alaska topping the list with the No. 1 longest workweeks in America. Alaska is the only state where workers clock in more than 40 hours per week at their jobs, with WalletHub reporting Alaskans work 41.4 hours on average weekly.

In the "indirect" work factors category — which encompassed workers' average commute times, the share of workers with multiple jobs, annual volunteer hours per resident, and the average leisure time spent per day — Texas ranked 36th nationwide.

Here's how WalletHub ranked Texas in three individual metrics:

No. 10 – Average commute times
No. 20 – Average leisure time spent per day
No. 30 – Employment rates

According to the World Economic Forum, Americans clock in about 1,800 hours at work per year on average, which is 468 more hours per year than workers in Germany. And many are leaving vacation time on the table, WalletHub says.

"Even when given the chance to take time off, many Americans won’t, as nearly half of workers don't expect to use all of their allotted vacation days," the report said. "It is possible to work hard without overdoing it, though. Hard work is key to success, and the residents of some states understand that better than others."

The top 10 hardest working states in America in 2026 are:

No. 1 – South Dakota
No. 2 – North Dakota
No. 3 – Alaska
No. 4 – Hawaii
No. 5 – Wyoming
No. 6 – Nebraska
No. 7 – Texas
No. 8 – New Hampshire
No. 9 – Tennessee
No. 10 – Georgia

Houston ranks No. 3 among rising coding markets in U.S.

city code

When you think of coders—the wizards who design, write and test programming languages for software and mobile apps—tech hotbeds like Silicon Valley and Austin might pop into your head.

But Houston has earned a spot on the coding map.

A new study puts the Houston area in third place among the fastest-growing metros for coding in the U.S.

The study, published by coding platform Coddy Tech, ranks Albuquerque, New Mexico, as the top on-the-rise market for coding. San Antonio sits in second place.

Houston earned a “momentum score” of 77 out of 100. The momentum category measured job growth for developers, rising interest in coding as measured by online searches, and growth in hackathon activity.

Here are the 10 fastest-rising U.S. metros for coding:

No. 1 Albuquerque, New Mexico
No. 2 San Antonio
No. 3 Houston
No. 4 Jacksonville, Florida
No. 5 Cape Coral, Florida
No. 6 Columbia, South Carolina
No. 7 New York City
No. 8 Salt Lake City
No. 9 North Port, Florida
No. 10 Tampa, Florida

The study analyzed the country’s 75 largest metros “to map where coding has taken hold and where it’s catching fire.” It took into account learning searches, GitHub developer density, job growth, interest in bootcamps and hackathon activity. Only 64 metros were eligible for the ranking of fastest-growing markets.

Austin tops ranking of coding capitals

Coddy crowned Austin the coding capital of the country, with Houston landing at No. 24 in the ranking of the most established coding hubs. San Antonio appeared at No. 16 and Dallas at No. 22.

Here are the top 10 coding hubs:

No. 1 Austin
No. 2 San Jose, California
No. 3 Seattle
No. 4 San Francisco
No. 5 New York City
No. 6 Salt Lake City
No. 7 Denver
No. 8 San Diego
No. 9 Los Angeles
No. 10 Raleigh, North Carolina

Why do coders matter?

Without coders, cellphones, laptops, smart TVs and other devices might not work well — or at all. Coding allows people to communicate with these devices, according to ComputerScience.org.

“Since computers do not communicate like humans, coding acts as a translator,” ComputerScience.org explains. “Code converts human input into numerical sequences that computers understand.”

NASA awards Texas Space Commission role in $10M aerospace workforce initiative

space hub

The Texas Space Commission is one of seven organizations tapped by NASA to lead the space agency's new state and regional Skilled Technical Workforce Hubs.

The $10.5 million initiative aims to help foster the next generation of skilled workers in the aerospace industry.

Through the new program, the hubs will work together over the next three years to meet growing industry needs by aligning “industry employers, community colleges, high school career and technical education programs, and workforce systems,” according to a news release from NASA.

It aims to create clear pathways for workers in technical jobs, like welding, electrical work and machining, plus other jobs that require advanced STEM knowledge but do not require a bachelor’s degree.

“The need for technical talent is already urgent and will only continue to grow as we return humanity to the Moon and set our sights on Mars and beyond,” Elaine Ho, associate administrator for the Office of STEM Engagement at NASA, said in the release. “NASA is uniquely positioned to be the catalyst and convener that accelerates America’s aerospace workforce development and fosters the next generation of technicians.”

As part of the initiative, the TSC plans to launch the statewide network known as the Texas Space STEM Alliance (TSSA). According to a TSC release, the TSSA will link up schools, colleges, workforce groups and aerospace companies to build a pipeline for space-industry workers.

Additionally, the TSC is developing the Texas Aerospace Pathways Plus (TAP+) portal to consolidate information on training programs, internships, apprenticeships, employment opportunities and scholarships, while also identifying regional gaps in workforce opportunities.

Other state and regional organizations to receive the award include:

Antelope Valley Community College District in Lancaster, California
Georgia Tech Research Corporation
Minnesota State Colleges and Universities
Southern Utah University
Space Florida
State Board for Community Colleges and Occupation Education, Arapahoe Community College in Littleton, Colorado

The Houston area is home to more than 43,000 aerospace and aviation professionals, according to the Greater Houston Partnership. The Texas Space Commission has been awarded $150 million for 24 projects since being established to increase the state’s space economy in 2023.

The funding for the NASA state hubs comes from NASA’s Office of STEM Engagement through its Next Gen STEM Project.
