Nanopatterning holograms onto commercial contact lenses

Mon, 04/30/2018 - 09:37
Researchers report a new a method to produce optical nanostructures on commercial contact lenses. This method aids in functionalizing and nanotexturing an of the shelf, commercial contact lens. This adds to the trend of the humble contact lens, widely used to correct common vision problems, being on its way to become a 'smart' diagnostic tool. Tears contain diagnostic information regarding ocular diseases, and they can be used as a surrogate medium for analyzing blood chemistry.

Energy-saving windows made from common glass and cheap nanocrystals

Fri, 04/27/2018 - 12:40
One of the main challenges for energy efficient technologies is to lower their cost by making cheap energy-efficient materials and devices by preferably using green manufacturing technologies. For example, commercial infrared-blocking windows, both passive and active, are simply too expensive (most of these IR-blocking windows contain an expensive silver coating) and they are not used in the majority of our homes. One approach to this problem involves creating passive infrared-blocking glasses using plasmonic nanocrystals. Researchers have demonstrated that nanocrystals of relatively inexpensive plasmonic materials show an overall good performance as IR-blocking elements.
