3D printing has helped create things like complex art and yachts, but some of the most life-changing applications have been made in biotech, where the relatively cheap process makes implants and bionic limbs accessible to those who may not otherwise have them.
The rapid development of flexible and wearable electronics is giving rise to an exciting range of applications, from smart watches and flexible displays — such as smart phones, tablets, and TV — to smart fabrics, smart glass, transdermal patches, sensors, and more. With this rise, demand has increased for high-performance flexible batteries.
Toyota’s New Electric Motor Cuts Need For Costly (And Overwhelmingly China-Sourced) Rare-Earth Metal
True to their name, permanent-magnet motors—such as those in the Prius Prime and most EVs and hybrids—incorporate magnets mounted directly on or within the rotor (the rotating component of the motor), while electric current is applied to the windings of the stator (the stationary portion of the motor). Magnets that produce the power needed for EVs are rare-earth magnets, a type that’s lighter and can produce a stronger field (and thus more torque) than old-style ferrite magnets.
When you throw certain elements together like hydrogen or oxygen, they can bond in pairs or even triplets, forming O2 (oxygen) or O3 (ozone), for instance. Shine two flashlights together, however and … crickets. The photons simply pass through each other like phantoms and there’s no reaction whatsoever. That’s because they have no mass or charge, though they can become highly energized in the form of X-rays or gamma rays.
The active component of the thermal resonator is a foam made up of copper or nickel that is infused with a phase-changing wax known as octadecane, which liquifies and solidifies at certain temperatures. The foamy mix is coated in a layer of graphene, which is an excellent thermal conductor.
