At the heart of all lithium-ion batteries is a simple reaction: Lithium ions dissolved in an electrolyte solution “intercalate” or insert themselves into a solid electrode during battery discharge. When they de-intercalate and return to […]

Designing a complex electronic device like a delivery drone involves juggling many choices, such as selecting motors and batteries that minimize cost while maximizing the payload the drone can carry or the distance it can […]

Palladium is one of the keys to jump-starting a hydrogen-based energy economy. The silvery metal is a natural gatekeeper against every gas except hydrogen, which it readily lets through. For its exceptional selectivity, palladium is […]

Yan Yao, a professor at University of Houston’s Cullen College of Engineering, along with collaborators from Singapore, Zhejiang University and Seoul National University, have published a review in the journal Science eying alternative metals for […]

Longer-lasting phones, lighter drones, electric cars that drive farther. These are just some of the possibilities thanks to a new battery separator design from University of Florida researchers and their partners.This post was originally published […]

A team of engineers from Polytechnique Montréal report a new and unique parachute concept inspired by the Japanese art of kirigami today in Nature. This simple, robust and low-cost approach has a wide variety of […]

Eight years after Hurricane Harvey devastated Houston in 2017, flooding hundreds of thousands of homes, the city still awaits a comprehensive flood protection system. The local flood control district estimates that at least one major […]

A new battery recycling method developed by Illinois Grainger engineers removes scarce, expensive metals from old battery cathodes and coats them onto new cathodes in a single step. The result is significantly more affordable, less […]

Time and again, unexploded aerial bombs from the Second World War need to be defused or detonated in controlled explosions. Researchers at the Fraunhofer Institute for High-Speed Dynamics, Ernst-Mach-Institut, EMI are working together with partners […]

New research led by the University of Cambridge, in collaboration with Hong Kong University of Science and Technology (GZ) and Queen Mary University of London, could redefine how we interact with everyday tools and devices—thanks […]
