Artificial bug eyes

ScienceDaily.com: Nanotechnology News - Wed, 01/09/2019 - 18:09
Single lens eyes, like those in humans and many other animals, can create sharp images, but the compound eyes of insects and crustaceans have an edge when it comes to peripheral vision, light sensitivity and motion detection. That's why scientists are developing artificial compound eyes to give sight to autonomous vehicles and robots, among other applications. Now, a new report describes the preparation of bioinspired artificial compound eyes using a simple low-cost approach.

Scientists use 2D h-BN nanosheets as the planar-alignment agent in a liquid crystal device to improve its optical transmission

NanoWerk.com - Wed, 01/09/2019 - 12:30
Researchers report an interesting phenomenon of two-dimensional (2D) hexagonal boron nitride (h-BN)-induced planar-alignment of a nematic liquid crystal and the subsequent optical and electro-optical effects. Liquid crystals (LCs) are optically anisotropic materials, and they are widely used in electro-optical display technology, known as liquid crystal displays (LCDs). Understanding the alignment phenomena of a nematic LC on a surface remains an important area of research, as the alignment process determines the LC?s molecular orientation and conformation - which influence the LC?s optical and electro-optical characteristics in LCDs.
