By structuring nanowires in a way that mimics geckos’ ears, researchers have found a way to record the incoming angle of light. This technology could have applications in robotic vision, photography and augmented reality.
New smart windows designed by Stanford engineers can change from transparent to dark or back again in under a minute depending on the light. The technology could be used in buildings, cars and even sunglasses.
Subjecting complex metal mixtures called high-entropy alloys to extremely high pressures could lead to finer control over the arrangement of their atoms, which in turn can result in more desirable properties.
