Researchers of the Center for Photonics and Two-Dimensional Materials at MIPT, together with their colleagues from Spain, Great Britain, Sweden, and Singapore, including co-creator of the world s first 2D material and Nobel laureate Konstantin Novoselov, have measured giant optical anisotropy in layered molybdenum disulfide crystals for the first time. The scientists suggest that such transition metal dichalcogenide crystals will replace silicon in photonics. Birefringence with a giant difference in refractive indices, characteristic of these substances, will make it possible to develop faster yet tiny optical devices. The work is published in the journal
Nature Communications.
Lifx’s bacteria-killing smart bulb works, but here’s the small print
These things take time

The Lifx Clean is a new smart lightbulb with an intriguing twist. Not only is it a fully functional color-changing lightbulb, the company also claims it is capable of disinfecting surfaces and the air around it. First announced last August, the $69.99 Lifx Clean is now shipping to preorder customers in the US, with wide availability planned this spring.
Lifx has an array of scientific studies as well as its own lab tests to support its claim that the Clean is the “world’s first antibacterial, germicidal smart light.” But can the lightbulb work as well in the average home as it did in the lab?
