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.

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."

New UT Austin med center, anchored by MD Anderson, gets $1 billion gift

Future of Health

A donation announced Tuesday, April 21, breaks a major record at the University of Texas at Austin. Michael and Susan Dell are now UT Austin's first supporters to give $1 billion. In response, the university will create the UT Dell Campus for Advanced Research and the UT Dell Medical Center to "advance human health," per a press release.

The release also records "significant support" for undergraduate scholarships, student housing, and the Texas Advanced Computing Center for supercomputing research.

Both the new research campus and the UT Dell Medical Center will integrate advanced computing into their research and practices. At the medical center, the university hopes that will lead to "earlier detection, more precise and personalized care, and better health outcomes." The University of Texas MD Anderson Cancer Center will also be integrated into the new medical center.

That comes with a numeric goal measured in 10s: raise $10 billion and rank among the top 10 medical centers in the U.S., both in the next decade.

In the shorter term, the university will break ground on the medical center with architecture firm Skidmore, Owings & Merrill (SOM) "later this year."

“UT Austin, where Dell Technologies was founded from a dorm room, has always been a place where bold ideas become real-world impact,” said Michael and Susan Dell in a joint statement.

They continued, “What makes this moment so meaningful is the opportunity to build something that brings every part of the journey together — from how students learn, to how discoveries are made, to how care reaches families. By bringing together medicine, science and computing in one campus designed for the AI era, UT can create more opportunity, deliver better outcomes, and build a stronger future for communities across Texas and beyond.”

This is the second major gift this year for the planned multibillion-dollar medical center. In January, Tench Coxe, a former venture capitalist who’s a major shareholder in chipmaking giant Nvidia, and Simone Coxe, co-founder and former CEO of the Blanc & Otus PR firm, contributed $100 million$100 million.

Baylor scientist lands $2M grant to explore links between viruses and Alzheimer’s

Alzheimer’s research

A Baylor College of Medicine scientist will begin exploring the possible link between Alzheimer’s disease and viral infections thanks to a $2 million grant awarded in March.

Dr. Ryan S. Dhindsa is an assistant professor of pathology & immunology at Baylor and a principal investigator at Texas Children’s Duncan Neurological Research Institute (Duncan NRI). He hypothesizes that Alzheimer’s may have some link to previous viral infections contracted by the patient. To study this intriguing possibility, the American Brain Foundation has gifted him the Cure One, Cure Many award in neuroinflammation.

“It is an honor to receive this support from the Cure One, Cure Many Award. Viral infections are emerging as a major, underappreciated driver of Alzheimer's disease, and this award will allow our team to conduct the most comprehensive screen of viral exposures and host genetics in Alzheimer's to date, spanning over a million individuals,” Dhindsa said in a news release. “Our goal is to identify which viruses matter most, why some people are more vulnerable than others, and ultimately move the field closer to new therapeutic strategies for patients.”

Roughly 150 million people worldwide will suffer from Alzheimer’s by 2050, making it the most common cause of dementia in the world. Despite this, scientists are still at a loss as to what exactly causes it.

Dhindsa’s research is part of a new range of theories that certain viral infections may trigger Alzheimer’s. His team will take a two-fold approach. First, they will analyze the medical records of more than a million individuals looking for patterns. Second, they will analyze viral DNA in stem cell-derived brain cells to see how the infections could contribute to neurological decay. The scale of the genomic data gathering is unprecedented and may highlight a link that traditional studies have missed.

Also joining the project are Dr. Caleb Lareau of Memorial Sloan Kettering Cancer Center and Dr. Artem Babaian of the University of Toronto. Should a link be found, it would open the door to using anti-virals to prevent or treat Alzheimer’s.

Tesla Robotaxi service officially launches in Houston and Dallas

Future of the Roads

Tesla’s Robotaxi service has taken to the streets of Houston. In a brief statement Saturday, April 18 on its X social media account, Tesla Robotaxi says the autonomous rideshare service just launched in Texas’ two biggest metro areas — Houston and Dallas.

“Try Tesla Robotaxi in Dallas & Houston!” Tesla CEO Elon Musk says in a reposting on X of the Robotaxi announcement.

One of Robotaxi’s competitors, Alphabet-owned Waymo, beat the Tesla service to the Dallas, Houston, and Austin markets. Another competitor, Amazon-owned Zoox, has Dallas flagged for its autonomous rideshare service.

Robotaxi previously kicked off in Austin, where Tesla is based and manufactures electric vehicles, and the San Francisco Bay Area. Nearly 50 Robotaxis operate in Austin, where the service’s inaugural rides happened last year, and more than 500 in the San Francisco area.

Of the three rides logged in a 31-square-mile area in Dallas as of Monday morning, the average fare was $7.96 and the average trip was 3.5 miles, according to an online tracker of autonomous rideshare services. The tracker showed only one Robotaxi was on the roads in Dallas.

As of Monday morning, a 25-square-mile area in Houston had two Robotaxis on the road, according to the online tracker. The average fare for five recorded rides was $11.34 and the average trip was six miles.

“We want Robotaxi pricing to be simple and easy for you to understand,” according to the Robotaxi website. “Initially, as part of our introductory program, we will charge a simple, affordable rate plus applicable taxes and fees for all rides within the available service area.”

The tracker shows the Robotaxi in Dallas did not have a human aboard to monitor each trip, and only one of Houston’s two Robotaxis did not have a human monitor in the driver’s seat.

For now, all passengers ride in Tesla Model Y cars. Robotaxi operates from 6 am-2 am daily.

To use the service, you first must download the Robotaxi app, which works only on iPhones.

Robotaxi lets you stream music and adjust climate settings and seat positioning from the Robotaxi app or the vehicle’s touchscreen. Climate and media settings are stored in your Robotaxi profile and automatically transfer from one vehicle to another. If you own a Tesla, certain profile settings and media preferences are available in your own car as well as in a Robotaxi.

In January at the World Economic Forum in Davos, Switzerland, Musk said a “widespread” network of driverless rideshare vehicles would be operating in the U.S. by the end of this year, CNBC reported.
