A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

Rice University named top college in U.S. News' new rankings for 2025

top of class

Houston's own "Ivy League of the South" has come out on top as one of the best universities in the nation for 2025, according to U.S. News and World Report's just-released list of the Best Colleges for 2025.

Rice University claimed No. 1 in Texas, and ranked No. 18 nationally in a one-spot slip from last year's ranking. The private institution has a 98 percent first-year retention rate, and an "actual" graduation rate of 96 percent. Rice costs $60,709 in tuition and fees for students each year, and according to the school's profile, it has an acceptance rate of eight percent.

In April, Rice's Jesse H. Jones Graduate School of Business ranked No. 2 in U.S. News' ranking of the best graduate schools in Texas, with its entrepreneurship program tying for No. 8 nationally, and the part-time MBA program ranking No. 15 overall. Those rankings may change in the next few years once the school finishes its brand new facility for the business school.

Rice also fared similarly in Niche'slist of best colleges, in which it ranked No. 15 nationally. Forbes ranked the university No. 9 nationwide in its list of best colleges for the 2024-2025 school year, and Rice was bestowed an "Ivy League" status in Forbes' recent report on top public and private schools that churn out top graduates.

“We are delighted to see Rice University recognized as one of America’s producers of great talent. Rice has been a recruiting destination for employers for many years and that is because Rice students are adaptable, curious, bright, and are solution oriented,” Nicole Van Den Heuvel, executive director of the Center for Career Development, says in a news release from Rice.

In a glowing review of the university, one former business student said studying at Rice was a "transformative experience."

"Rice is the perfect blend of rigorous academics, strong athletics, and a nurturing and engaging social life," the reviewer wrote. "It's quite idyllic. Rice is known as a STEM school, but it has distinguished programs in humanities, social sciences, music and architecture too. Professors are top scholars in their fields and will know you by name. Students are well prepared academically, but are also collaborative and supportive."

Right behind Rice in the rankings is The University of Texas at Austin, which ranked No. 2 in Texas and No. 30 nationally. Just behind UT Austin is College Station's Texas A&M University, which placed No. 3 in the Texas rankings and No. 51 nationally.

The University of Houston maintained its No. 8 rank in the statewide comparison, but fell 11 spots down into No. 144 in the national rankings.

The University of St. Thomas ranked No. 9 in Texas, and moved up seven places to rank No. 209 in the U.S. for 2025.

U.S. News' top 10 best colleges in Texas in 2024 are:

  • No. 1 – Rice University, Houston
  • No. 2 – University of Texas at Austin
  • No. 3 – Texas A&M University, College Station
  • No. 4 – Baylor University, Waco
  • No. 5 – Southern Methodist University, Dallas
  • No. 6 – Texas Christian University, Fort Worth

Houston-area schools score spots on of annual list of top universities for patents issued

new report

The University of Houston System reigns as the patent king among colleges and universities in the Houston area.

A new list from the National Academy of Inventors puts UH in a 63rd-place tie — with 27 utility patents issued in 2023 — among 100 recognized schools. As the university explains, utility patents are among the world’s most valuable assets because they give inventors exclusive commercial rights to produce and use their technology.

Other schools in the Houston area that show up on the list are the Texas A&M University System, tied for 30th place with 66 patents, and Rice University, tied for 93rd place with 14 patents.

The University of Rochester in New York shares the No. 63 spot with UH.

“This ranking highlights the commitment of our faculty researchers, who explore frontiers of knowledge to enhance the well-being of our society,” Ramanan Krishnamoorti, vice president of energy and innovation at UH, says in a news release. “At UH, we are committed to creating new technologies that drive innovation, to boost Houston’s economy and tackle some of the most perplexing problems facing us.”

Among the UH discoveries that received utility patents last year are:

  • Methods of targeting cancer stem cells
  • Materials, systems, and methods for carbon capture and conversion.
  • A medical device that positions and tracks the muscular activity of legs.

Elsewhere in Texas:

  • University of Texas System, holding the No. 3 spot with 235 patents
  • Texas Tech University System, tied for 74th place with 20 patents
  • Baylor University, tied for 80th place with 17 patents
  • University of North Texas, tied for 90th place with 15 patents

Ahead of the UT System on the list are the University of California (546 patents) and the Massachusetts Institute of Technology (365 patents).

“As we look at the current and future state of innovation in our nation, we need to ensure that the U.S. is remaining competitive in the international innovation ecosystem,” Paul Sanberg, president of the National Academy of Inventors, says in a news release. “Protecting intellectual property is a key component to this, and the … list allows us to recognize and celebrate universities and their faculty, staff, and students who are not only innovating at high levels but taking the additional step of protecting their IP through patenting.”

University of Houston joins $5M consortium for national defense innovation

looking smart

The University of Houston has signed on to be a part of an organization that is working toward next-gen technology for defense purposes.

UH has announced its partnership with the Department of Defense Spectrum Innovation Center’s Spectrum Management with Adaptive and Reconfigurable Technology (SMART) Hub, which aims to conduct spectrum research to help with national defense needs. SMART Hub will develop next-generation technologies, and the research team will contribute expertise in spectrum security, economics, communication systems, radar, circuits, policy, and more.

The center is led by Baylor University, and is a collection of researchers, engineers, and economic and policy experts looking to “enact a paradigm shift in the use and management of the wireless spectrum” according to SMART Hub. The consortium is worth $5 million, and comes after UH recently awarded its largest grant in history—$63.5 million from the U.S. DoD. The previous DoD contract aims to support the campus in developing analytical modeling and simulation platforms for the U.S. Army.

Growth in use of electronic devices has led to the jamming of the bandwidth available in the wireless spectrum (radio, TV, wireless phone signals). SMART Hub will focus on new approaches of spectrum communication to assist military and corporate organizations that will confront this issue more than before. SMART Hub will combine efforts of 29 researchers at 17 institutions.

“We will be working on groundbreaking technology that will revolutionize how we use the spectrum,” professor of electrical and computer engineering at Baylor and director of the efforts Charles Baylis said in a news release. “Rather than fixed systems that use the same frequency and stay there, we’re designing systems that can adapt to their surroundings and determine how to successfully transmit and receive. It’s a true paradigm shift that requires the type of collaboration we will have in SMART Hub.”

UH’s SMART Hub team, which will be tasked to produce strategies for enhanced communication in challenging spaces like regions having electromagnetic interference, forests, inner city environments, or mountainous terrains, includes:

  • David Jackson, professor of electrical and computer engineering
  • Zhu Han, Moores Professor of electrical engineering
  • Daniel Onofrei, associate professor of mathematics

Texas plugs in among states at highest risk for summer power outages in 2025

hot, hot, hot

Warning: Houston could be in for an especially uncomfortable summer.

A new study from solar energy company Wolf River Electric puts Texas at No. 2 among the states most at risk for power outages this summer. Michigan tops the list.

Wolf River Electric analyzed the number of large-scale outages that left more than 5,000 utility customers, including homes, stores and schools, without summertime electricity from 2019 to 2023. During that period, Texas experienced 7,164 summertime power outages.

Despite Michigan being hit with more summertime outages, Texas led the list of states with the most hours of summertime power outages — an annual average of 35,440. That works out to 1,477 days. “This means power cuts in Texas tend to last longer, making summer especially tough for residents and businesses,” the study says.

The Electric Reliability Council of Texas (ERCOT), which operates the electric grid serving 90 percent of the state, predicts its system will set a monthly record for peak demand this August — 85,759 megawatts. That would exceed the current record of 85,508 megawatts, dating back to August 2023.

In 2025, natural gas will account for 37.7 percent of ERCOT’s summertime power-generating capacity, followed by wind (22.9 percent) and solar (19 percent), according to an ERCOT fact sheet.

This year, ERCOT expects four months to surpass peak demand of 80,000 megawatts:

  • June 2025 — 82,243 megawatts
  • July 2025 — 84,103 megawatts
  • August 2025 — 85,759 megawatts
  • September 2025 — 80,773 megawatts

One megawatt is enough power to serve about 250 residential customers amid peak demand, according to ERCOT. Using that figure, the projected peak of 85,759 megawatts in August would supply enough power to serve more than 21.4 million residential customers in Texas.

Data centers, artificial intelligence and population growth are driving up power demand in Texas, straining the ERCOT grid. In January, ERCOT laid out a nearly $33 billion plan to boost power transmission capabilities in its service area.

Houston ranks among top 5 cities for corporate HQ relocations in new report

h-town HQ

The Houston area already holds the title as the country’s third biggest metro hub for Fortune 500 headquarters, behind the New York City and Chicago areas. Now, Houston can tout another HQ accolade: It’s in a fourth-place tie with the Phoenix area for the most corporate headquarters relocations from 2018 to 2024.

During that period, the Houston and Phoenix areas each attracted 31 corporate headquarters, according to new research from commercial real estate services company CBRE. CBRE’s list encompasses public announcements from companies across various sizes and industries about relocating their corporate headquarters within the U.S.

Of the markets included in CBRE’s study, Dallas ranked first for corporate relocations (100) from 2018 to 2024. It’s followed by Austin (81), Nashville (35), Houston and Phoenix (31 each), and Denver (23).

According to CBRE, reasons cited by companies for moving their headquarters include:

  • Access to lower taxes
  • Availability of tax incentives
  • Proximity to key markets
  • Ability to support hybrid work

“Corporations now view headquarters locations as strategic assets, allowing for adaptability and faster reaction to market changes,” said CBRE.

Among the high-profile companies that moved their headquarters to the Houston area from 2018 to 2024 are:

  • Chevron
  • ExxonMobil
  • Hewlett-Packard Enterprise
  • Murphy Oil

Many companies that have shifted their headquarters to the Houston area, such as Chevron, are in the energy sector.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, said in 2024. “With deep roots in our region, Chevron is a key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

According to CBRE, California (particularly the San Francisco Bay and Los Angeles areas) lost the most corporate HQs in 2024, with 17 companies announcing relocations—12 of them to Texas. Also last year, Texas gained nearly half of all state-to-state relocations.

In March, Site Selection magazine awarded Texas its 2024 Governor’s Cup, resulting in 13 consecutive wins for the state with the most corporate relocations and expansions.

In a news release promoting the latest Governor’s Cup victory, Gov. Greg Abbott hailed Texas as “the headquarters of headquarters.”

“Texas partners with the businesses that come to our great state to grow,” Abbott said. “When businesses succeed, Texas succeeds.”

CBRE explained that the trend of corporate HQ relocations reflects the desire of companies to seek new environments to support their goals and workforce needs.

“Ultimately, companies are seeking to establish themselves in locations with potential for long-term success and profitability,” CBRE said.

SpaceX test rocket explodes in Texas, but no injuries reported

SpaceX Update

A SpaceX rocket being tested in Texas exploded Wednesday night, sending a dramatic fireball high into the sky.

The company said the Starship “experienced a major anomaly” at about 11 pm while on the test stand preparing for the 10th flight test at Starbase, SpaceX’s launch site at the southern tip of Texas.

“A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,” SpaceX said in a statement on the social platform X.

CEO Elon Musk ’s SpaceX said there were no hazards to nearby communities. It asked people not to try to approach the site.

The company said it is working with local officials to respond to the explosion.

The explosion comes on the heels of an out-of-control Starship test flight in late May, which tumbled out of control. The FAA demanded an investigation into the accident.
