To develop batteries that last longer on a single charge, more energy must be stored within the same size and weight.
Florida State University will establish a campus-scale quantum communication testing platform with $2.1 million in federal Community Project Funding through the National Institute of Standards and Technology, secured with support from U.S. Rep. Daniel Webster of Florida's 11th Congressional District.
Researchers synthesized Al-substituted Na5FeS4 positive electrode materials for all-solid-state sodium batteries and found that slight aluminum substitution increased apparent sodium-ion transport while preserving high capacity. Na5Fe0.95Al0.05S4 delivered about 500 mAh g-1 in initial testing, maintained more than 460 mAh g-1 for over 70 cycles, and showed reversible sulfur-related structural changes during cycling.
A new approach that uses light to switch the magnetic states of a material could lead to faster, smaller and more energy-efficient data storage.
When a spacecraft reenters Earth's atmosphere at hypersonic velocities, its protective heat shield faces the most extreme conditions, including temperatures beyond 3,000 degrees Fahrenheit.
A Husker research team's latest milestone could open the door to broader use of a class of materials whose electrical properties may someday power next-generation electronics, high-density energy storage, improved computer memory and new strategies for cooling.
The study models light-duty EV and PHEV batteries across Europe through 2045, linking vehicle adoption, operating lifetimes, used-vehicle trade, evolving chemistries, second-life storage, and recycling efficiencies to estimate the recoverable amounts of lithium, cobalt, nickel, and manganese. It projects a sharp rise in recoverable material from the late 2020s, but recycled-content targets remain difficult to meet, especially for cobalt, and high reuse reduces the cumulative material available for recycling by about 20%–25% over the study period.
For decades, nonproliferation scientists and engineers at the U.S. Department of Energy's Argonne National Laboratory have helped convert the fuel in dozens of research reactors around the world so that they operate safely and more securely.
As governments and industry increase investment in quantum technologies, Element Six is helping bridge the gap between laboratory research and deployable solutions.
A rocket launch is not for the faint of heart - and certainly not for sensitive electronics either. Nevertheless, satellites must survive the vibrations during launch unscathed. In collaboration with the Swiss space company Beyond Gravity, Empa researchers have developed a solution to mitigate these dangerous vibrations.
