Focusing on the Unhealthy Brain to Speed Drug Discovery

Badri Roysam, Hugh Roy and Lillie Cranz Cullen University Professor and Chair of Electrical and Computer Engineering, and his team are working with the NIH to develop open-source tools that will treat concussions and other brain injuries and diseases.

Though 40 million concussions are recorded annually, no effective treatment exists for them or for many other brain-related illnesses. In collaboration with Dragan Maric of the National Institutes of Health, Badri Roysam, Hugh Roy and Lillie Cranz Cullen University Professor and Chair of Electrical and Computer Engineering, and his team are working to speed up drug development to treat brain diseases and injuries like concussion by developing new tools. 

Tapping the Brain to Boost Stroke Rehabilitation

A clinical trial found that stroke survivors gained clinically significant arm movement and control by using an external robotic device powered by the patients’ own brains.
Clinical Trial Suggests Brain-Machine Interface Coupled with Robot Offers Increased Benefits for Stroke Survivors

Stroke survivors who had ceased to benefit from conventional rehabilitation gained clinically significant arm movement and control by using an external robotic device powered by the patients’ own brains.

A Safer, Less Expensive and Fast Charging Aqueous Battery

Xiaonan Shan, assistant professor of electrical and computer engineering, said the discovery offers promise for energy storage and other applications, including electric vehicles.

Lithium-ion batteries are critical for modern life, from powering our laptops and cell phones to those new holiday toys. But there is a safety risk – the batteries can catch fire.

Zinc-based aqueous batteries avoid the fire hazard by using a water-based electrolyte instead of the conventional chemical solvent. However, uncontrolled dendrite growth limits their ability to provide the high performance and long life needed for practical applications.

Discoveries Highlight New Possibilities for Magnesium Batteries

Researchers from the University of Houston and the Toyota Research Institute of North America have reported a breakthrough in the development of magnesium batteries, allowing them to deliver a power density comparable to that of lithium-ion batteries.

New cathode, electrolyte allow high-power battery previously considered impossible

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered.

New Technology Allows More Precise View of the Smallest Nanoparticles

Wei-Chuan Shih, professor of electrical and computer engineering at UH, is the corresponding author for a paper about a new optical imaging technology for nanoscale objects, relying upon unscattered light to detect nanoparticles as small as 25 nanometers in diameter.

Imaging Technology Offers Advantages for Diagnostics, Other Uses

Current state-of-the-art techniques have clear limitations when it comes to imaging the smallest nanoparticles, making it difficult for researchers to study viruses and other structures at the molecular level.

UH, Houston Methodist using AI to identify breast cancer

Dr. Hien Van Nguyen, an Assistant Professor of Electrical and Computer Engineering at the University of Houston's Cullen College of Engineering, has received a grant to use AI with breast cancer diagnoses.

Dr. Hien Van Nguyen, an Assistant Professor of Electrical and Computer Engineering at the University of Houston's Cullen College of Engineering, received an R01 sub-award of $319,285 for his grant, “Convergent AI for Precise Breast Cancer Risk Assessment,” from the National Cancer Institute, National Institutes of Health.

A Roadmap to Better Multivalent Batteries

Lithium-ion batteries are recognized for their high energy density in everything from mobile phones to laptop computers and electric vehicles, but as the need for grid-scale energy storage and other applications becomes more pressing, researchers have sought less expensive and more readily available alternatives to lithium.

New $1M Hardware Project Would Boost 5G Networks

Harish Krishnamoorthy, assistant professor of electrical and computer engineering at UH, is creating a roadmap to boost the development of 5G networks.

There are big advantages to 5G networks. In addition to faster speeds, 5G offers greater bandwidth and network capacity, paving the way for a future of driverless cars, connected devices and more high-definition connections for virtual meetings and telemedicine. But the rollout in the United States and elsewhere has been stymied by gaps in available technology that could operate at the high frequencies required by 5G.

Researchers Report High Performance Solid-State Sodium-Ion Battery

ORGANIC CATHODE OFFERS MORE RELIABLE CONTACT WITH ELECTROLYTE, A KEY TO STABILITY

 

Solid-state sodium-ion batteries are far safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers Friday reported developing an organic cathode that dramatically improves both stability and energy density.
