Engineers have developed pressure-sensing photonic fibers that they have woven into a typical compression bandage. As the bandage is stretched, the fibers change color. Using a color chart, a ...

In a step towards developing advanced materials for functional coatings, a research group has developed a technology that combines structural color coating with super water-repellent properties. The ...

A single layer of silicon nanospheres produces bright structural colors that are independent of the viewing angle. The color can be controlled by the diameter of the spheres, where smaller particles ...

Over the next few years, the batteries that go into electric vehicles are going to get cheap enough that an EV should cost no more than an equivalent-sized vehicle with an internal combustion engine.

From electric planes that can only fly for so long to electric cars that need to pull over for a recharge every few hundred miles, heavy, bulky batteries are a huge, limiting factor in how far these ...
