Tech Xplore / Polymers with ultralow dielectric loss show potential for 6G telecommunications
With the rollout of fifth-generation (5G) telecommunications networks and 6G looming on the horizon, the demand for advanced materials that can handle high-frequency signals is rising rapidly. These systems use electromagnetic ...
Tech Xplore / Engineers gain new tool to design complex systems with built-in uncertainty
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 ...
Tech Xplore / Simple formula could guide the design of faster-charging, longer-lasting batteries
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 ...
Tech Xplore / Kirigami parachute suitable for humanitarian missions stabilizes quickly and doesn't pitch
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 potential ...
Tech Xplore / Organic semiconductor molecule set to transform solar energy harvesting
In a discovery that bridges a century of physics, scientists have observed a phenomenon, once thought to be the domain of inorganic metal oxides, thriving within a glowing organic semiconductor molecule. This work, led by ...
Tech Xplore / Shape-changing robots: New AI-driven design tool optimizes performance and functionality
Like octopuses squeezing through a tiny sea cave, metatruss robots can adapt to demanding environments by changing their shape. These mighty morphing robots are made of trusses composed of hundreds of beams and joints that ...
Tech Xplore / AI model can manipulate time to make better predictions in a wide range of fields
In the world around us, many things exist in the context of time: a bird's path through the sky is understood as different positions over a period of time, and conversations as a series of words occurring one after another.
Tech Xplore / One-atom-thick filter helps lithium–sulfur batteries keep their charge
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.
Tech Xplore / Battery cathode recycling achieved with single-step process
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, ...
Tech Xplore / Palladium filters could enable cheaper, more efficient generation of hydrogen fuel
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 ...
Tech Xplore / Graffiti framework lets people personalize online social spaces while staying connected with others
Say a local concert venue wants to engage its community by giving social media followers an easy way to share and comment on new music from emerging artists. Rather than working within the constraints of existing social platforms, ...
Tech Xplore / Security researchers say G1 humanoid robots are secretly sending information to China and can easily be hacked
Researchers have uncovered serious security flaws with the Unitree G1 humanoid robot, a machine that is already being used in laboratories and some police departments. They discovered that G1 can be used for covert surveillance ...
