Rice University’s Office of Technology Transfer has signed a subscription agreement with California-based Intel Corp., giving the global company access to Rice’s research portfolio and the opportunity to license select patented innovations.

“By partnering with Intel, we are creating opportunities for our research to make a tangible impact in the technology sector,” Patricia Stepp, assistant vice president for technology transfer, said in a news release.

Intel will pay Rice an annual subscription fee to secure the option to evaluate specified Rice-patented technologies, according to the agreement. If Intel chooses to exercise its option rights, it can obtain a license for each selected technology at a fee.

Rice has been a hub for innovation and technology with initiatives like the Rice Biotech Launch Pad, an accelerator focused on expediting the translation of the university’s health and medical technology; RBL LLC, a biotech venture studio in the Texas Medical Center’s Helix Park dedicated to commercializing lifesaving medical technologies from the Launch Pad; and Rice Nexus, an AI-focused "innovation factory" at the Ion.

The university has also inked partnerships with other tech giants in recent months. Rice's OpenStax, a provider of affordable instructional technologies and one of the world’s largest publishers of open educational resources, partnered with Microsoft this summer. Google Public Sector has also teamed up with Rice to launch the Rice AI Venture Accelerator, or RAVA.

“This agreement exemplifies Rice University’s dedication to fostering innovation and accelerating the commercialization of groundbreaking research,” Stepp added in the news release.

group project

Rice University’s OpenStax and Microsoft are partnering to integrate the nonprofit’s content with the tech giant’s AI innovation, known as Learning Zone.

“At OpenStax, our mission is to make an amazing education accessible to all,” Richard G. Baraniuk, founder and director of OpenStax, said in a news release. “That’s why we’re excited to integrate our trustworthy, peer-reviewed content with Microsoft’s AI technology through the Microsoft Learning Zone. Together, we aim to help more instructors and their students access engaging, effective learning experiences in new and dynamic ways. We also share a strong commitment to the thoughtful and responsible application of AI to better ensure all learners can succeed.”

OpenStax is a provider of affordable instructional technologies and is also one of the world’s largest publishers of open educational resources (OER).

Microsoft Learning Zone promises to provide educators and students with “responsible AI technology and peer-reviewed educational content to support learning” on Microsoft Copilot+ PCs. Microsoft Learning Zone works by utilizing on-device AI to generate interactive lessons for students, and its integration with OpenStax content means educators can rely on OpenStax’s digital library of 80 openly licensed titles.

The goal is for educators to create effective and engaging learning experiences safely, thereby bypassing the need to source and vet content independently. Included is a library of ready-to-use lessons, opportunity for immediate feedback and differentiated learning. Educators will maintain control of instructional content and pedagogical strategies and will be able to update or edit lessons or activities prior to sharing them with students.

Other tools included in the Microsoft Learning Zone are additional languages, reading coaching, public speaking help, math and reading progress, and a partnership with the online quiz platform Kahoot!

OpenStax resources have been reported as used across 153 countries, and this current collaboration combines the power and potential of responsible AI usage in education with content that has been utilized by 13,569 K-12 schools and 71 percent of U.S. colleges and universities, according to Rice.

“Through our partnership with OpenStax, we’re combining the power of on-device AI in Copilot+ PCs with OpenStax’s trusted and diverse peer-reviewed content to help educators quickly create high-quality, personalized, engaging lessons,” Deirdre Quarnstrom, vice president of Microsoft Education, added in the news release. “We’re excited about how this collaboration will empower classrooms globally.”

While Milkify's founders — husband and wife team Pedro Silva and Berkley Luck — secured partners on a popular business pitch and investment show, the entire experience almost didn't happen.

Silva and Luck, who got her PhD in molecular and biomedical s at Baylor College of Medicine, founded the company to provide breast milk freeze drying as a service to Houston-area families. Now, Milkify has customers across the country, but the duo didn't know if going through the process would be worth the investment and publicity, or if it would just be a distraction.

"The competitor in me wanted to be the first breast milk company to go on the show and to tell our story to the world — to show the world what my wife came up with that we thought was so great," Silva says on the Houston Innovators Podcast. "It was probably the scariest 45 minutes of my life." Read more.

Anthony Palmiotto, director of higher education at OpenStax

In an effort to combat the hefty price tag of assigned texts, OpenStax, a nonprofit education startup out of Rice University, which is on a mission to increase educational access for all, seeks to democratize high-quality education by offering free, peer-reviewed, openly licensed textbooks for students and knowledge seekers across the globe.

This month, OpenStax will add to its 57 open education resources, or OER, titles with a full version of John McMurry's popular pre-med textbook, Organic Chemistry, under an open license to honor his late son, Peter, who passed away in 2019 after losing his battle with cystic fibrosis.

“Before the nursing books, we were doing business books,” Anthony Palmiotto, director of higher education at OpenStax, tells InnovationMap. “Murry’s book builds out our science offerings, so we're thinking about the different areas that students take that can be barriers for them to move up in education and succeed. From there, we’ll continue to think about how a free textbook can help students through that process.” Read more.

Last week, Houstonian and business consultant Brad Deutser published his book, BELONGING RULES: Five Crucial Actions that Build Unity and Foster Performance. In a guest column for InnovationMap, Deutser writes of the importance of belonging in the workplace with his colleague Isabel Bilotta, managing consultant and head of learning and innovation at Deutser's learning initiative.

"Although there are many definitions out there, we define belonging as where we hold space for something of shared importance," the article reads. "It is where we come together on values, purpose, and identity; a space of acceptance where agreement is not required but a shared framework is understood; where there is an invitation into the space; an intentional choice to take part in; something vital to a sense of connection, security, and acceptance."

Growing Houston tech nonprofit expands access to textbooks for college students

openstax updates

If everyone that attended a college or university were polled, they’d all likely agree that one of the worst parts of the experience was the rising costs of textbooks.

In an effort to combat the hefty price tag of assigned texts, OpenStax, a nonprofit education startup out of Rice University, which is on a mission to increase educational access for all, seeks to democratize high-quality education by offering free, peer-reviewed, openly licensed textbooks for students and knowledge seekers across the globe.

This month, OpenStax will add to its 57 open education resources, or OER, titles with a full version of John McMurry's popular pre-med textbook, Organic Chemistry, under an open license to honor his late son, Peter, who passed away in 2019 after losing his battle with cystic fibrosis.

“The author, John McMurry, granted us the ability to publish the 10th edition openly,” Anthony Palmiotto, director of higher education at OpenStax, tells InnovationMap. “So, the most widely used organic chemistry textbook went from being one of the most expensive undergraduate texts on the market (almost $100), to a free and open text, making this a watershed moment for OER.”

This school year, OpenStax is adding 16 academic institutions onto its platform, including Georgia State University, Southwest Texas Junior College, Texas A&M University-Commerce, University of San Diego, and more. It's the largest batch of new schools OpenStax has onboarded in a year, Palmiotto says in a news release.

Founded to increase access

OpenStax founder and director Richard Baraniuk, a professor of Electrical and Computer Engineering at Rice University, started the OER publisher in 1999 to remove financial barriers and make educational resources more widely available. Much like increasing access to McMurry’s Organic Chemistry, the goal is to continue to support both learners and educators by providing easily accessible and well-developed materials.

“Our mission is to support all learners in their educational pursuits by providing access to high-quality education,” Palmiotto says. “Richard Baraniuk founded it initially as a way for faculty and others to get their material and their knowledge in the form of textbooks and other learning materials to students.

“And then born out of that, we started this robust textbook development and course material development program where we put out the highest-quality materials we can in a way that fits the way courses are taught. Meaning convenience and scope and sequence and other needs that instructors must use textbooks. So really the access was really the start of it, increasing that and lowering barriers to education, and then a lot flowed from that.”

OpenStax’s library of OER titles, which are published under a Creative Commons Attribution license, are free and easily accessible on the go and usable on any device in multiple formats, including digital and PDF.

Funded by philanthropic supporters, OpenStax normally works to openly access five or six books per year, working mostly on introductory courses. Most recently, the Texas Higher Education Coordinating Board funded the publisher to do a series of nursing books, eight in total.

“Before the nursing books, we were doing business books,” Palmiotto says. “Murry’s book builds out our science offerings, so we're thinking about the different areas that students take that can be barriers for them to move up in education and succeed. From there, we’ll continue to think about how a free textbook can help students through that process.”

Tapping into tech

In addition to nursing, OpenStax is working towards releasing books in data science and computer science, including programming, workplace software and, eventually, artificial intelligence.

“AI is a big deal to us,” says Palmiotto. “We're thinking about it a lot, and in the books themselves, we're incorporating as best we can how AI plays into Data Science, Computer Science and Python Programming those. We’re thinking about how AI could be used and will impact programming, for example. But the AI landscape is changing as we go, and that's another reason we don't just put out the books, we maintain them.

“So, we can continually update them. Once we publish, six months later, we can publish updates or additions to reflect what's happening in courses or in professions or in the workforce to reflect how AI is being used as new software is released and so on.”

As OpenStax continues to build on its OER title database, they are using multiple methods of outreach to reach as many people as possible. Currently, they have over 7.5 million users in the formal education space, primarily in higher education introductory courses, as well as grades K–12.

“Over 140 countries are using our material,” says Palmiotto. “We're not as easily able to track how many students have used our material in all those other countries. But that's not the point, we want to put it out there. We know it's being used. We want to help as much as possible. But it is being used in all those countries and in different ways. Some people are translating it. Some people are using it in English. Some people are breaking it up. It just depends on what they need.”

Evolving the industry

As much as OpenStax is a disrupter to conventional textbook publishers, they would rather work in partnership with publishers like Murry’s former house Cengage rather than outright replacing them.

“What we've tried to do with those publishers is actually partner with them and say, we know that textbook prices were too high,” says Palmiotto. “Some of them partnered with us, Cengage, Riley, some of the other publishers, like Macmillan, incorporate our textbooks into their platforms so that instructors and students have that flexibility even with those publishers.

“Not every publisher wants to do that. That's their choice. But what we've tried to do is say ‘let's make an ecosystem.’ That's what we call it and let them participate in this movement that open education has become.”

With their textbooks on an open forum, it might seem that OpenStax texts would be susceptible to hacking or other unauthorized changes. But, according to Palmiotto, there’s a safeguard to that.

“We keep the standard version,” he says. “That's why a lot of people keep using it because they know that the version that we provide will be the most up-to-date version. But it is openly licensed. So, if we see that a school wants to teach the course in a slightly different way or if they want to recombine two different books to make a different course, take biology and make human biology, or take philosophy and make ethics or something, they can do that.

“But we still retain the standardized version that we redistribute and make sure that that's the high-quality one that people can look to. So nobody is getting back to our version and changing it, but they do have the opportunity to change their own.”

After more than a decade in the space, OpenStax repeatedly receives feedback from users worldwide that appreciate the openness and availability of their books.

“We have some great stories of different learners from all over the world that are non-traditional students facing barriers,” says Palmiotto. “And having a free textbook and not having to choose between food and their book or courseware makes a huge difference in their lives. If they have this flexibility in what they have to purchase, most people appreciate that choice.”

These 5 trailblazing Houston startups are leading the energy transition

meet the finalists

Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

Houston businessman and philanthropist to receive legendary Texas award

Making History

The Texas State History Museum Foundation (TSHMF) has set the date for its 23rd annual Texas Independence Day Dinner and unveiled the 2027 recipients of its prestigious History-Making Texan Award, which includes a prominent Houston businessman.

Since 2005, the organization has honored "living Texas legends whose contributions to the state and the nation have been truly historic and exceptional in scope and nature." Past galas have recognized prominent Texas figures such as former presidents George H.W. and George W. Bush and former first ladies Barbara and Laura Bush, as well as H-E-B chairman Charles Butt, among others.

The two 2027 History-Making Texan Award recipients are Texas Historical Commission chairman, businessman, and philanthropist John L. Nau, III, and trailblazing Texas actor, director, producer, and writer Taylor Sheridan. The 2027 gala will be held at the Bullock Texas State History Museum in Austin on March 2, Texas Independence Day.

"Our honorees are national leaders whose accomplishments have elevated Texas’ distinctive place on the national and international stage," Debbie Raynor, dinner chair and TSHMF Trustee, said in a statement. "John L. Nau, III and Taylor Sheridan have each, in very different ways, helped tell the Texas story — one through the preservation of our history and treasured places, the other through the power of storytelling that has brought Texas and the American West to audiences around the world.

"Nau is the former chairman and CEO of Silver Eagle Beverages, one of the largest Anheuser-Busch distributors in the U.S. He has served as chairman of the Texas Historical Commission since 2015. Raynor said Nau's "commitment to preservation" extends further than his protection of Texas historic sites "to the stewardship and conservation of the land itself, including his bay area lodge in South Texas and his ranch in West Texas.

"[Nau's] leadership and lifelong dedication to history have earned him national recognition, but perhaps his greatest legacy is his determination to ensure that the stories and places that shaped Texas endure for generations to come," Raynor said.Quadruple-threat filmmaker Sheridan is most widely recognized for his award-winning neo-Western TV series Yellowstone and its associated spin-offs 1883, 1923, Marshals, and Dutton Ranch. Raynor hailed Sheridan for his success in bringing a "remarkable new dimension to the way the world sees Texas and the American West."

"As a creator, writer, director, and executive producer of some of television’s most successful series, he has captured the imagination of audiences across the globe while bringing the people, landscapes, traditions and enduring spirit of the West into millions of homes," she said. "And he does more than tell the Texas story — he lives it, as a native Texan, accomplished horseman and steward of two legendary Texas ranches."

A release estimates about 450 "business, political, and community leaders" attend the Texas Independence Day Dinner each year, and proceeds will benefit the Bullock Museum's educational programs and special projects.

The 2027 Texas Independence Day Dinner will take place March 2, 2027, at the Bullock Museum in Austin. A VIP reception will start at 6:30 pm, followed by a 7 pm reception, and 7:30 dinner and program.

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.
