Researchers at Rice University, in collaboration with Oak Ridge National Laboratory, have developed a new model that could lead to sharper imaging and safer diagnostics using magnetic resonance imaging, or MRI.

In a study recently published in The Journal of Chemical Physics, the team of researchers showed how they used the Fokker-Planck equation to better understand how water molecules respond to contrast agents in a process known as “relaxation.” Previous models only approximated how water molecules relaxed around contrasting agents. However, through this new model, known as the NMR eigenmodes framework, the research team has uncovered the “full physical equations” to explain the process.

“The concept is similar to how a musical chord consists of many notes,” Thiago Pinheiro, the study’s first author, a Rice doctoral graduate in chemical and biomolecular engineering and postdoctoral researcher in the chemical sciences division at Oak Ridge National Laboratory, said in a news release. “Previous models only captured one or two notes, while ours picks up the full harmony.”

According to Rice, the findings could lead to the development and application of new contrast agents for clearer MRIs in medicine and materials science. Beyond MRIs, the NMR relaxation method could also be applied to other areas like battery design and subsurface fluid flow.

“In the present paper, we developed a comprehensive theory to interpret those previous molecular dynamics simulations and experimental findings,” Dilipkumar Asthagiri, a senior computational biomedical scientist in the National Center for Computational Sciences at Oak Ridge National Laboratory, said in the release. ”The theory, however, is general and can be used to understand NMR relaxation in liquids broadly.”

The team has also made its code available as open source to encourage its adoption and further development by the broader scientific community.

“By better modeling the physics of nuclear magnetic resonance relaxation in liquids, we gain a tool that doesn’t just predict but also explains the phenomenon,” Walter Chapman, a professor of chemical and biomolecular engineering at Rice, added in the release. “That is crucial when lives and technologies depend on accurate scientific understanding.”

The study was backed by The Ken Kennedy Institute, Rice Creative Ventures Fund, Robert A. Welch Foundation and Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory.

Houston foundation doles out $700K for Texas chemical research

fresh funding

Houston-based The Welch Foundation has issued $700,000 in additional funding to support chemical research through two of its newest grant programs.

The foundation has named the recipients of its Welch eXperimental (WelchX) Collaboration Retreat and Pilot Grants and the Welch Postdoctoral Fellows of the Life Sciences Research Foundation Grants.

The WelchX grants were awarded to teams of two Texas researchers who presented "innovative and collaborative ideas" addressing challenges in the clean energy space, according to the foundation.

Researchers from Texas universities gathered in Houston earlier this summer to discuss the theme “Chemical Research for Grand Challenges." They then paired off into nine teams and submitted proposals for the $100,000 pilot grants. The seven selected teams, several with ties to Houston, and their research topics include:

  • Yimo Han, Rice University, and Yuanyue Liu, The University of Texas at Austin, “Stabilizing Copper Electrocatalysts for CO2 Conversion”
  • Ognjen Miljanic, University of Houston, and Indrajit Srivastava, Texas Tech University, “Ping-Pong' Afterglow Luminescence in Self-Assembled Molecular Cubes”
  • Raúl Hernández Sánchez, Rice University, and Andy Thomas, Texas A&M University, “Accelerating Magnetic Resonance Imaging Contrast Agent Discovery via Rapid Injection NMR: Improving the Detection of Lithium for Disease Diagnostics”
  • Benjamin Janesko, Texas Christian University, and MD Masud Rana, Lamar University, “Cyber Twin Chemical Ensembles for Near-Infrared-Emitting Graphene Quantum Dot Therapeutics”
  • Ivan Korendovych, Baylor University, and Dino Villagrán, The University of Texas at El Paso, “Selective Bio-Inspired Electrochemical Probes for PFAS Analysis and Degradation”
  • Samantha Kristufek, Texas Tech University, and Kayla Green, Texas Christian University, “CIRCUIT: Critical Ion Recovery using Conductive and Ultrafiltration Intelligent Technology”
  • Fang Xu, The University of Texas at San Antonio, and Hong Wang, University of North Texas, “Visualize Molecular Adsorption on Supported Ni-porphyrin Model Catalysts via Substitute Effect”

The Welch Postdoctoral Fellows of the Life Sciences Research Foundation provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas.

The foundation previously announced that it would name fellows from Rice University and Baylor University who would receive $100,000 annually for three years. This year's recipients and their research topics include:

  • Teng Yuan, Rice University, “Unlocking New Chemistry of Nonheme Iron Enzymes for α-Amino Acids and γ-Lactones Synthesis”
  • Katelyn Baumler, Baylor University, "Crystal Growth of Ln2Fe4Sb5 Phases Toward the Study of Novel Quantum Properties”

“As these programs become more established, it is thrilling to see the new research our awardees are exploring,” Adam Kuspa, president of The Welch Foundation, said in a news release. “The Foundation is very pleased by the applications that we continue to receive describing exciting new research projects to advance chemical research.”

This additional funding comes on the heels of the foundation doling out $27 million for chemical research, equipment and postdoctoral fellowships earlier this summer. The foundation made 85 grants to faculty at 16 Texas institutions at the time. Read more here.

fresh funding

Two local professors are among the newly announced recipients of funding from the Houston-based Welch Foundation, which finances chemical research projects.

The two professors are:

  • Jacinta Conrad, the Frank M. Tiller Professor in the Chemical and Biomolecular Engineering Department at the University of Houston. Conrad will use her grant to investigate glass transition, a temperature change that affects polymers. She describes glass transition as one of the “most intriguing open problems in physical chemistry.”
  • James Shee, assistant professor in the Chemistry Department at Rice University. Shee will put his grant toward advancing theoretical chemistry.

Every year, the foundation provides annual grants totaling at least $100,000 to support chemistry research being carried out by full-time faculty members at colleges, universities, and other educational institutions in Texas.

In all, the Welch Foundation on June 4 announced more than $40.5 million in academic research grants, equipment grants, and fellowships.

Part of the announced funding will go toward the foundation’s new Postdoctoral Fellows Grant Program. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. A total of $900,000 in postdoctoral fellowships were funded at Rice University, Texas A&M University, and the University of Texas at Austin.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs, and other chemistry-related ventures.

“Ongoing basic chemical research is critically important for helping to solve current and future problems,” said Adam Kuspa, President of the Welch Foundation. “We strongly believe the foundation’s continued support of the research grant program, combined with … new programs, will yield even more exciting developments as we work to advance chemistry and improve our lives.”

Houston innovator receives $5M to establish new center that explores crystallization process

crystal clear initiative

A new hub at the University of Houston is being established with a crystal-clear mission — and fresh funding.

Thanks to funding from Houston-based organization The Welch Foundation, the University of Houston will be home to the Welch Center for Advanced Bioactive Materials Crystallization. The nonprofit doled out its inaugural $5 million Catalyst for Discovery Program Grant to the new initiative led by Jeffrey Rimer, Abraham E. Dukler Professor of Chemical Engineering, who is known internationally for his work with crystals that help treat malaria and kidney stones.

“Knowledge gaps in the nascent and rapidly developing field of nonclassical crystallization present a wide range of obstacles to design crystalline materials for applications that benefit humankind, spanning from medicine to energy and the environment,” says Rimer in a news release. “Success calls for a paradigm shift in the understanding of crystal nucleation mechanisms and structure selection that will be addressed in this center.”

The Welch Foundation, which was founded in 1954, has granted over $1.1 billion to scientists in Texas. This new grant program targets researchers focused on fundamental chemical solutions. Earlier this year, the organization announced nearly $28 million in grants to Texas institutions.

"Support from the Welch Foundation has led to important advances in the field of chemistry, not only within Texas, but also throughout the United States and the world as a whole,” says Randall Lee, Cullen Distinguished University Chair and professor of chemistry, in the release. “These advances extend beyond scientific discoveries and into the realm of education, where support from the Welch Foundation has played a significant role in building the technological workforce needed to solve ongoing and emerging problems in energy and health care.”

Rimer and Lee are joined by the following researchers on the newly announced center's team:

  • Peter Vekilov, Moores Professor, chemical and biomolecular engineering
  • Alamgir Karim, Dow Chair and Welch Foundation Professor, chemical and biomolecular engineering;
  • Jeremy Palmer, Ernest J. and Barbara M. Henley Associate Professor, chemical and biomolecular engineering
  • Gül Zerze, chemical and biomolecular engineering
  • Francisco Robles Hernandez, professor of engineering technology.

The University of Houston also received another grant from the Welch Foundation. Megan Robertson, UH professor of chemical engineering, received $4 million for her work with developing chemical processes to transform plastic waste into useful materials.

“For the University of Houston to be recognized with two highly-competitive Welch Foundation Catalyst Grants underscores the exceptional talent and dedication of our researchers and their commitment to making meaningful contributions to society through discovery,” Diane Chase, UH senior vice president for academic affairs and provost, says in the release.

Houston organization announces nearly $28M in Texas research grant funding

money moves

Five schools in the Houston area have landed $10.8 million in research grants from the Houston-based Welch Foundation.

The 36 grants were awarded to Rice University, Texas A&M University, the University of Houston, the Baylor College of Medicine, and the University of Texas Medical Branch in Galveston.

In all, the foundation announced nearly $28 million in Texas research grants for 2023. All of the money — in the form of 91 grants for 15 Texas colleges and universities — goes toward chemical research. This year’s total for grant funding matches last year’s total.

“The Welch Foundation continues to emphasize the creative pursuit of basic chemical research,” Adam Kuspa, the foundation’s president and a former dean at the Baylor College of Medicine, says in a news release. “Our funding allows investigators throughout the state to follow their curiosity and explore the foundations chemical processes.”

Since its establishment in 1954, the Welch Foundation has contributed about $1.1 billion to the advancement of chemistry in Texas.

One of this year’s local grant recipients is Haotian Wang, assistant professor in Rice’s chemical and biomolecular department. The professor’s grant-funded research will focus on the conversion of carbon dioxide into useful chemicals, such as ethanol.

Last year, Rice reported that Wang’s lab in the George R. Brown School of Engineering had replaced rare, expensive iridium with ruthenium, a more abundant precious metal, as the positive-electrode catalyst in a reactor that splits water into hydrogen and oxygen.

The lab’s addition of nickel to ruthenium dioxide resulted in production of hydrogen from water electrolysis for thousands of hours.

“There’s huge industry interest in clean hydrogen,” Wang says. “It’s an important energy carrier and also important for chemical fabrication, but its current production contributes a significant portion of carbon emissions in the chemical manufacturing sector globally.”

“We want to produce it in a more sustainable way,” he adds, “and water-splitting using clean electricity is widely recognized as the most promising option.”

Rice University announces leader of new materials and nanotechnology institute

at the helm

A recently established institute at Rice University has revealed its new leader.

The Rice Advanced Materials Institute has named Lane Martin as director. Martin will also serve as Welch Professor of Materials Science and NanoEngineering in the George R. Brown School of Engineering. He begins both roles on July 1.

“Lane is everything we expect our faculty to be — hard-working, committed to excellence, dedicated to students and collaborative across disciplines,” says Howard R. Hughes Provost Amy Dittmar in a news release. “I look forward to seeing Rice faculty and students reap the benefits of his leadership.”

Prior to his appointment at Rice, Martin was the chancellor’s professor of materials science and engineering at the University of California, Berkeley. He also served as chair of the materials science and engineering department, faculty scientist in the material sciences division of the Lawrence Berkeley National Laboratory, and co-director of the Collaborative for Hierarchical Agile and Responsive Materials, according to the release.

“I had the privilege of mentoring Lane when he was a doctoral student at Berkeley,” says Ramamoorthy Ramesh, vice president for research, professor of materials science and nanoengineering and professor of physics and astronomy. “He is a gifted scientist with the boldness and vision to build this new institute into a research powerhouse.”

The new institute was created following a $100 million gift from Houston-based Welch Foundation. It will bring together chemistry, materials science, machine learning, and artificial intelligence to revolutionize the future of industry.

“This institute will keep Rice at the forefront of high-impact research related to energy transition, advanced materials and future computing,” says Luay Nakhleh, the William and Stephanie Sick Dean of the school, in the release. “It will empower our faculty and students to help solve some of the most pressing problems of our day.”

Venus Aerospace adds government, C-suite leaders following $91M raise​

new leaders

Fresh off its $91 million Series B, Houston-based Venus Aerospace has made several key additions and promotions to its leadership team.

The company says its expanded team will help it deploy its high-thrust rotating detonation rocket engine (RDRE), which completed its first U.S. flight test last summer.

"We flew the world's first high-thrust RDRE in just over four years on $80 million. We believe that makes it the fastest, most capital-efficient rocket engine program in history," Sassie Duggleby, co-founder and CEO of Venus Aerospace, said in a news release. "Adding this talent to our leadership team is how we bring that same discipline to the company itself, as we scale to meet the technical needs of defense and space customers who need range and speed legacy systems can't deliver."

The key hires include:

Lane Bodian, Vice President of Public Policy

Bodian previously served as the Principal Deputy Assistant Secretary of Defense for Legislative Affairs at the Pentagon.

Dan Rebnord, Director of Federal Government Relations

Rebnord most recently served as Senior Policy Advisor to a member of the Senate Armed Services Committee and previously worked in the Office of Legislative Affairs at the Department of Defense and as Staff Director for a national security subcommittee in the House of Representatives. Rebnord and Bodian will lead Venus' work with government stakeholders.

Tom Barron, Chief Operating Officer

Barron was promoted from his role as vice president of operations for Venus Aerospace. Before his time at Venus, he served as Special Assistant to the Secretary of Defense and consulted aerospace clients at McKinsey & Company. He also served as a U.S. Army Infantry and Special Forces officer.

Nick Cardwell, Chief Product Officer

Cardwell was promoted from his role as vice president of research and development. He previously held product and technology leadership roles at VC-backed tech companies in the San Francisco Bay Area and Austin.

Venus also named Cameron Taylor as its new vice president of operations, Sarah Boland Heine as its head of communications, Matt Stohr as its head of business development, and Sheila Menz as general counsel.

The company also announced a joint technology development agreement to advance the RDRE with defense giant Lockheed Martin last week. Through the partnership, Venus and Lockheed will focus on evaluating the RDRE's propulsion architecture in defense systems, specifically for precision fires applications where weapons are designed to accurately strike targets at long distances.

Lockheed Martin Ventures, the investment arm of the aerospace and defense contractor, is an investor in Venus Aerospace.

"Lockheed Martin is focused on rapidly delivering advanced capabilities that strengthen deterrence and provide decisive advantages for the warfighter," Tim Cahill, president, Lockheed Martin Missiles and Fire Control, said in a news release. "Our collaboration with Venus Aerospace allows us to evaluate a promising propulsion technology and determine how it can be integrated into future precision fires solutions. Efforts like this help accelerate innovation, reduce risk and shorten the path from emerging technology to operational capability."

Venus' RDRE is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus says the reusable, affordable and scalable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types. The company has previously estimated that the hypersonic market is projected to surpass $12 billion by 2030.

New report ranks Houston as America's No. 2 least safe city

Ranking It

A new study contains bad news for Houston. A report from personal finance website SmartAsset ranks the Bayou City as the second-least safe city in the U.S. among cities with at least 250,000 residents.

Only Memphis ranked worse than Houston.

The 2026 study looked at 83 U.S. cities' violent crimes, property crimes, traffic deaths, and disaster risk.

Houston fared poorly in all four: 11.5 violent crimes per 1,000 residents, 42.9 property crimes per 1,000 residents, 11.6 traffic deaths per 100,000 residents, and “very high” risk for natural disasters, which makes sense in a city prone to tropical weather and flooding.

For all cities in the study, disaster risk and traffic deaths were measured at the county level.

Houston is the only Texas city to rank in the bottom 10. The other cities are:

  • 1. Memphis, Tennessee
  • 2. Houston, Texas
  • 3. St. Louis, Missouri
  • 4. San Francisco, California
  • 5. Kansas City, Missouri
  • 6. Albuquerque, New Mexico
  • 7. Oakland, California
  • 8. Nashville, Tennessee
  • 9. Philadelphia, Pennsylvania
  • 10. Detroit, Michigan

“While no major population center is entirely free from danger, some are more successful than others at creating environments where people can live, work and travel with confidence,” SmartAsset says.

Although this study paints Houston in a poor light, other reports take a more positive view. The "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy ranked as No. 9 in America out of 393 cities with a population of 500,000 or more. Houston also boasts Texas’ 10th best park system, according to its ParkScore Index.

While SmartAsset has bad news for Houston, the Dallas suburb of Plano ranked as the study’s second-safest big city. Compared to Houston, Plano fared well in three of the four categories: 1.5 violent crimes per 1,000 residents, 14.7 property crimes per 1,000 residents, and 6.9 traffic deaths per 100,000 residents. Its only shortcoming is a “relatively high” risk for natural disasters.

Elsewhere in Texas:

  • Fort Worth ranked No. 22
  • Austin ranked No. 26
  • San Antonio ranked No. 54
  • Dallas ranked No. 73
