A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.

Houston METRO partnership receives $1.5M federal grant to bring electric buses to the Third Ward

hop on

Get ready to ride a new fleet of zero emission shuttles from Houston METRO. Global consulting firm AECOM and METRO partnered on new electric bus initiative and have recently been granted $1.5 million from the Federal Transit Administration to bring the service to Texas Southern University, University of Houston, and Houston's Third Ward neighborhood.

The grant was awarded through the FTA's Accelerating Innovative Mobility, or AIM, initiative and was one of only 25 initiatives across the U.S. to receive FTA funding. The new buses are expected to be fully operational in spring of next year.

"The shuttle will connect to METRO buses and light rail and be studied for potential use in urban, suburban, and rural environments," says Kim Williams, METRO's chief innovation officer, in a news release. "Our industry continues to evolve with new technology that prioritizes clean air quality."

AECOM will manage, plan, and provide engineering support services for the project for METRO, which is a founding member of AECOM's Automated Bus Consortium.

"We're thrilled to work with our longtime partner, METRO, on this exciting AIM initiative and to further progress mobility and innovation in the transit industry while helping our clients achieve their sustainability goals," says Andrew Bui, AECOM's vice president of global transportation electrification, in the release.

"This project will strengthen our ongoing efforts through our Automated Bus Consortium and contribute to Houston's already expansive work in deploying emerging technologies," Bui adds.

The vehicle will be provided by the project's partner Phoenix Motorcars, which makes zero emission, all-electric vehicles via software from EasyMile, a leader in cutting-edge autonomous technology.

Mayor announces major effort to reduce emissions on Houston's roadways

Easy EVs

The city of Houston has taken a major step toward reducing carbon emissions caused by its estimated 1.3 million vehicles that drive the city's streets daily.

Mayor Sylvester Turner announced a new partnership between the government, local businesses, and academic leaders that has created EVolve Houston. The coalition is aimed at boosting electric vehicle sales to 30 percent of new car sales in Houston by 2030.

"This new partnership will help solidify Houston's success as a leader in transportation technology and it will help improve air quality for the citizens of Houston and beyond, by reducing reliance on vehicles powered by carbon-based fuels," Mayor Turner says in a release. "Houston will now have a dedicated resource working to increase the adoption of electric vehicles, wherever it makes sense to do so. Nearly half of the greenhouse gas emissions in Houston come from transportation. Shifting to zero emission forms of transportation is a key strategy to help us meet our ambitious climate goals and improve our regional air quality."

EVolve Houston, which will contribute to the city's Climate Action Plan that was announced in July, will focus on increasing awareness, affordability, and availability of electric vehicles. The coalition's founding partners include the city, CenterPoint Energy, the University of Houston, NRG Energy, Shell, and LDR.

"Houston has bold goals to improve air quality and reduce greenhouse gas emissions. To do that, we must make a major impact on one of the largest sources of emissions, which is transportation" says Dr. Ramanan Krishnamoorti, the chief energy officer at University of Houston.

The partners will focus on launching pilot projects as well as hosting demonstrations and awareness activities to promote EV adoption, according to the release.

"At CenterPoint Energy, we are committed to making a positive difference in the communities we touch, and environmental stewardship is an integral component of our overall corporate responsibility approach," says Scott Prochazka, president and CEO of CenterPoint Energy, in the release. "I am proud to partner with Mayor Turner and other founding members of EVolve Houston to help accelerate clean transportation for Houston."

Rice University MBA programs rank among top 5 in prestigious annual report

top of class

Rice University’s Jones Graduate School of Business MBA programs have been ranked among the top five in the country again in The Princeton Review’s 2025 Best Business Schools rankings.

The university's MBA program in finance earned a No. 3 ranking, climbing up two spots from its 2024 ranking. Finance MBA programs at the University of Virginia's Darden Graduate School of Business and New York University's Leonard N. Stern School of Business were the only ones to outrank Rice, claiming No. 2 and No. 1 spots, respectively.

Rice's online MBA program was ranked No. 5, compared to No. 4 last year. Indiana University's Bloomington Kelley School of Business' online program claimed the top spot.

“These rankings reflect the commitment of our faculty and staff, the drive and talent of our students and the strong support of our alumni and partners,” Peter Rodriguez, dean of Rice Business, said in a news release. “They are exceptional honors but also reminders — not just of our top-tier programs and world-class faculty and students but of our broader impact on the future of business education.”

Rice also ranked at No. 6 for “greatest resources for minority students."

The Princeton Review’s 2025 business school rankings are based on data from surveys of administrators at 244 business schools as well as surveys of 22,800 students enrolled in the schools’ MBA programs during the previous three academic years.

"The schools that made our lists for 2025 share four characteristics that inform our criteria for designating them as 'best': excellent academics, robust experiential learning components, outstanding career services, and positive feedback about them from enrolled students we surveyed," Rob Franek, The Princeton Review's editor-in-chief, said in a press release. "No b-school is best overall or best for all students, but to all students considering earning an MBA, we highly recommend these b-schools and salute them for their impressive programs."

Rice's finance program has ranked in the top 10 for eight consecutive years, and its online MBA has ranked in the top five for four years.

Rice and the University of Houston also claimed top marks on the Princeton Review's entrepreneurship rankings. Rice ranks as No. 1 on the Top 50 Entrepreneurship: Grad list, and the University of Houston ranked No. 1 on Top 50 Entrepreneurship: Ugrad. Read more here.

Houston named ‘star’ metro for artificial intelligence in new report

eyes on AI

A new report declares Houston one of the country’s 28 “star” hubs for artificial intelligence.

The Houston metro area appears at No. 16 in the Brookings Institution’s ranking of metros that are AI “stars.” The metro areas earned star status based on data from three AI buckets: talent, innovation and adoption. Only two places, the San Francisco Bay Area and Silicon Valley, made Brookings’ “superstar” list.

According to Brookings, the Houston area had 11,369 job postings in 2024 that sought candidates with AI skills, 210 AI startups (based on Crunchbase data from 2014 to 2024), and 113 venture capital deals for AI startups (based on PitchBook data from 2023 to 2024).

A number of developments are boosting Houston’s AI profile, such as:

Brookings also named Texas’s three other major metros as AI stars:

  • No. 11 Austin
  • No. 13 Dallas-Fort Worth
  • No. 40 San Antonio

Brookings said star metros like Houston “are bridging the gap” between the two superstar regions and the rest of the country. In 2025, the 28 star metros made up 46 percent of the country’s metro-area employment but 54 percent of AI job postings. Across the 28 metros, the number of AI job postings soared 139 percent between 2018 and 2025, according to Brookings.

Around the country, dozens of metros fell into three other categories on Brookings’ AI list: “emerging centers” (14 metros), “focused movers” (29 metros) and “nascent adopters” (79 metros).
