(Press-News.org) Michele Galizia, a President’s Associates Presidential Professor in the School of Sustainable Chemical, Biological and Materials Engineering at the University of Oklahoma, is leading a research team that recently received a grant from the U.S. Department of Energy that will develop improved polymer membranes to advance molecular separation and related materials science.
“We currently separate chemicals, gases and liquids using a thermal-based distillation technology that is very expensive to operate and consumes the equivalent of eight GJ of electricity per person on the planet per year,” Galizia said. “So, our goal is to develop next-generation devices for large-scale gas separation using polymer membranes instead of distillation.”
“These membranes must exhibit adequate long-term stability of at least three years if we want to make these processes feasible and profitable,” he added.
Galizia is working alongside Alberto Striolo, in the School of Sustainable Chemical, Biological and Materials Engineering, and Marco Buongiorno Nardelli at the University of North Texas. Together they are focusing on fundamental science, using principles of chemistry and physics and taking inspiration from other fields to develop better materials.
“Our team is leveraging molecular simulations to select the monomers needed to make new polymer membranes,” Galizia said. “These new membranes would use 1,000 times less energy to separate mixtures than it would take to distill it.”
If the researchers are successful, this membrane technology has potential applications in many fields, including fossil fuels, healthcare, the airline industry and more.
“There really is a variety of separations that we could run,” Galizia said. “These include carbon dioxide separation from natural gas, olefine-paraffin separations, hydrogen separation and recovery, solvents separation and many others. We just need more selective and durable membranes, which is exactly what we want to do in this project.”
This multidisciplinary project not only aligns with the University of Oklahoma’s strategic plan but also provides an opportunity to educate future materials scientists.
“Our job is to educate the next generation workforce and the leaders of the future,” Galizia said. “That’s why we’re doing this.”

About the Study
The project, “Discovering the mechanism by which polymer porous networks reduce physical aging and plasticization while enhancing permeability and selectivity in microporous polymer membranes,” is funded by an expected $700,000 grant from the U.S. Department of Energy’s Office of Basic Energy Sciences, Award no. DE-SC0024554. The project began on Sept. 1, 2023, and is expected to conclude on Aug. 31, 2026.

Living systems—unlike non-living or inanimate objects—use information about their surrounding environment to survive. But not all information from the environment is meaningful or relevant for survival. The subset of information that is meaningful, and perhaps necessary for being alive, is called semantic information.
In a new paper published in PRX Life, University of Rochester physicists and their coauthors have, for the first time, applied this theory of semantic information to a well-known ...
Researchers have identified a new way to screen genes that cause several different types of cancers to grow, identifying particularly promising targets for precision oncology in oral and esophageal squamous cancers.
The study, published in this month’s issue of Cell Reports, used 3-dimensional models of organ tissues called organoids to identify and test potential gene targets from The Cancer Genome Atlas.
“There’s a tremendous amount of data in The Cancer Genome Atlas, ...
Over the past decades, increasing evidences have demonstrated that five retinoids, including retinol (ROL), retinol acetate (RAc), retinol propionate (RP), retinol palmitate (RPalm), and hydroxypinacolone retinoate (HPR), can be potential therapeutic agents for skin photoaging. However, therapeutic efficacies and biosafety have never been compared to these compounds. This study aimed to determine the optimal retinoid type(s) for anti-photoaging therapy both in vitro and in vivo.
The data demonstrated that four retinoids (RPalm, RP, HPR and ROL) but not RAc were effective for anti-photoaging treatment at 5 μg/mL in vitro, with action mechanisms associated with antioxidative, ...
As more medications move toward federal approval for Alzheimer’s disease, a new study led by researchers at UC San Francisco and Kaiser Permanente Washington has found that personalized health and lifestyle changes can delay or even prevent memory loss for higher-risk older adults.
The two-year study compared cognitive scores, risk factors and quality of life among 172 participants, of whom half had received personalized coaching to improve their health and lifestyle in areas believed to raise the risk of Alzheimer’s, such as uncontrolled diabetes and physical inactivity. These participants were ...
November 28, 2023-- Inadequate health coverage is a particular problem for commercially insured children, according to a new study released by Columbia University Mailman School of Public Health. The research shows that coverage gaps are affecting publicly insured children as well. Until now, prior research had focused on documenting rates and trends in insurance consistency for children covered by all insurance types. The findings are published in JAMA Health Forum.
“While uninsurance among children has generally been declining in the U.S., our results highlight the need for a renewed focus on making sure that children’s ...
DETROIT – A Wayne State University College of Engineering professor has received a $2.65 million award from the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health to develop a novel filtration platform to improve an advanced drug delivery device to optimize diabetes insulin treatments.
Subcutaneous insulin administration (SIA) technology has improved significantly over the past two decades, but SIA technology failure and underlying tissue damage caused by insulin phenolic preservatives ...
ROCHESTER, Minn. — Mayo Clinic’s Board of Trustees has approved Bold. Forward. Unbound. in Rochester, a multiyear strategic initiative that advances Mayo Clinic’s Bold. Forward. strategy to Cure, Connect and Transform healthcare for the benefit of patients everywhere. It reimagines Mayo Clinic’s downtown Rochester campus and introduces new facilities with a combination of innovative care concepts and digital technologies that will give Mayo Clinic the ability to scale transformation ...
While doctors and nurses were hailed as the frontline heroes of the COVID-19 pandemic, their counterparts in public health were experiencing threats. During the pandemic, threats against public health workers reached an all-time high. After the vaccine was released, those threats increased and changed in nature, according to a longitudinal study conducted during the first year of the pandemic by Jennifer Horney, founder of the University of Delaware Epidemiology Program in the College of Health Sciences.
The results, recently published in an open-access commentary in Public Health in Practice, show a strong need for expanded legal protections ...
The U.S. must reduce racial residential segregation if it is to reduce racial disparities in health outcomes, according to a recently published study by researchers at Tufts University School of Medicine. The research on 220 metropolitan areas nationwide between 1980 and 2020 found strong links between trends in racial residential segregation and racial disparities in early death rates from a variety of causes.
The study is the first known to examine the association between changes in racial segregation over time ...
