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.”

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.”

Houston leads U.S. with the biggest surge in millionaire renters

Rent Report

The number of millionaire renters and homeowners in the U.S. has surged over the last five years, and Houston has soared ahead of the rest with the largest growth rate among these affluent renter households.

Houston leads the nation with the No. 1 increase in millionaire renters from 2020 to 2024, a new RentCafe study found. The number of these wealthy households increased from 18 to 232 over the last five years, representing a 1,189 percent growth rate.

"The pandemic accelerated the shift as remote work pushed the wealthy to relocate to lower-tax metros like Houston, where millionaire renters grew 13-fold, versus 3.9-fold for owners," the report said. "Granted, 232 households is still a tiny fraction of the Houston metro’s roughly 2.7 million households, but the growth rate far outpaces any other major metro."

Nationwide, the number of millionaire renter households grew 229 percent from 2020 to 2024, outpacing the 193 percent growth rate among millionaire homeowners.

Dallas was the only other Texas metro to crack the top 10. The number of millionaire renter households in North Texas has more than quintupled, from just 30 in 2020 to 165 in 2024. That represents a growth rate of 450 percent, which — surprisingly — is only the eighth highest nationwide.

But when it comes to the largest populations of millionaire renters, New York City and San Francisco still lead the way. New York claimed the No. 1 spot with nearly 7,300 millionaire renters living in the city in 2024. Houston ranked 12th on that list.

Elsewhere in Texas, Austin and Dallas ranked as the 16th and 17th, respectively, for the largest population of millionaire renters. There were 206 millionaire renters living in Austin in 2024, and 165 in Dallas.

This is who the typical millionaire renter is
The report also revealed a surprising statistic about the typical millionaire renter in the U.S. — a lot of them are millennials working in "white-collar, high-earning fields."

"Nearly half (49 percent) of millionaire renters are Millennials, and the number of affluent Millennial renter households surged 392 percent during the five-year period," the report said. "Gen X follows with 33 percent of millionaire Gen X households renting after increasing by 147 percent."

The report continued, "Although Gen Z still represents a small share of millionaire renters (just 2 percent of the total), no generation has expanded faster: Gen Z millionaire renter households leaped from fewer than a dozen to more than 400 — a tiny cohort today, but one that was virtually nonexistent five years ago."

The top three most common professions for millionaire renters are chief executives, software developers, and managers, the report additionally found. In Houston, the surge of wealthy newcomers are mostly executives, professional athletes, and entertainers.

"These roles tend to generate steady, substantial income without necessarily tying workers to one location, making renting a practical fit, rather than a financial necessity," the report said.

Hotspots for millionaire homeowners
In RentCafe's separate list comparing the top 10 most popular U.S. metros for millionaire homeowners, Houston ranked 12th nationally with 4,374 millioniare homeowners living in the metro as of 2024. These wealthy Houstonians are most likely working as chief executives, physicians, managers, and lawyers and judges.

Houston has already proven to be a hotspot for millennial homebuyers, and the latest RentCafe data says millennials make up 19 percent of all millionaire homeowners in the U.S. Gen Xers and Baby Boomers still maintain the largest shares of millionaire homeowners nationwide, at 45 and 33 percent, respectively.

Dallas (No. 10) and Austin (No. 20) also appeared among the hottest metros for millionaire homeowners.

Only one Texas city appeared among RentCafe's list of the 20 fastest-growing metros for millionaire homeowners: College Station ranked 13th nationwide with a growth rate of 1,329 percent. From 2020-2024, the number of millionaire homeowners residing in College Station grew from 14 to 200.

Houston ranks high on best cities for small-business expansion report

business growth

For small businesses looking to expand, Houston might be the right place.

Among 56 major U.S. metros, Houston grabbed the No. 6 spot on a new list of the metros boasting the strongest environments for small-business expansion.

A 2025 report from the state comptroller’s office showed roughly 970,000 small businesses operate in the 13-county Gulf Coast region. The region includes the majority of the Houston metro area.

“Whether it’s a family-owned shop on Main Street or a fast-growing startup, small businesses power our state’s economic engine, create opportunity, and strengthen the character of every Texas community,” Kelly Hancock, who was interim state comptroller when the report was released, said in a press release.

Business lending platform Clarify Capital analyzed five factors to develop the list: job growth, business entry and exit, net job creation, and unemployment.

Overall, the Nashville area claimed the No. 1 spot on the list. Other major Texas metros also cracked the top 10, including Austin at No. 3 and Dallas-Fort Worth at No. 7.

“The highest-ranking metros combine labor-market momentum with steady business formation and relatively favorable local employment conditions,” Clarity Capital says.

The Houston metro ranked sixth for job growth, 11th for business entry rate, 38th for business exit rate, second for net job creation rate, and 50th for unemployment rate.

“For business owners, the ranking is a starting point rather than a guarantee,” Clarify Capital says. “Local demand, competition, operating costs, and access to capital still shape whether an expansion works.”

“Building enough cash-flow room for hiring, equipment, and unexpected expenses can help small and midsize business owners take advantage of a strong market without stretching the business too thin,” the company adds.

Of course, money fuels small-business expansion in the Houston area or anywhere else.

According to an analysis of SBA loan data by feasibility consulting firm MMCG, the Houston metro area saw 1,685 approvals for 7(a) loans and 101 approvals of 504 loans in the federal government’s 2025 budget year. The approval numbers for both loan categories increased from the previous year.

Altogether, the 7(a) and 505 loans exceeded $1 billion.

The data from the U.S. Small Business Administration suggests small-business expansion may be on the rise in the Houston area.

Further potential evidence of small-business expansion in the Houston area: The region experienced a 92 percent rise in account applications from 2024 to 2025 submitted to Bluevine, a small-business banking platform. The Houston metro ranked fifth for the number of Bluevine small-business applications in 2025.
