“Because this device can stretch, we now can paste a display on things with complex shapes, like skin,” Someya said. It can be placed on the human body for a week without causing skin inflammation, and is light enough that users might eventually even forget they are wearing it.
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.
Boeing Leads Investment In New High Energy Density Battery That Could Eventually Enable Electric Flight
Batteries are currently taking over ground transport with electric cars and trucks, but battery technology is improving so quickly that it is soon expected to spread to air transport soon.
It is even possible to capture images from light particles that have never even interacted with the object we want to photograph. This would take advantage of the idea of “quantum entanglement”, that two particles can be connected in a way that means whatever happens to one happens to the other, even if they are a long distance apart. This has intriguing possibilities for looking at objects whose properties might change when lit up, such as the eye. For example, does a retina look the same when in darkness as in light?
