Dense yet transparent materials offer new way to control light

Researchers recently made the surprising discovery that a special class of materials called "hyperuniform materials" can be both dense and transparent. This work demonstrates a new way to control light and could lead to novel ...

Low-reflection wings make butterflies nearly invisible

The effect is known from the smart phone: Sun is reflected by the display and hardly anything can be seen. In contrast to this, the glasswing butterfly hardly reflects any light in spite of its transparent wings. As a result, ...

2-D nitrogenated crystals new potential rival for graphene

Researchers in South Korea have, for the first time, developed a simple technique to produce a two-dimensional nitrogen-containing crystal that has the capacity to be a potential rival to graphene and silicon as semi-conductor ...

Researchers develop cheaper 'smart windows'

Researchers from the Spanish National Research Council (CSIC) have developed a novel technique that reduces the costs of the 'smart windows', with which the amount of light passing through glass can be controlled. This technology ...

'Smart glass' micro-iris for smartphone cameras

A small, low-powered camera component made from a "smart glass" material has been created by a group of researchers in Germany with the hope of inspiring the next generation of smartphone cameras.

New study reveals communications potential of graphene

Providing secure wireless connections and improving the efficiency of communication devices could be another application for graphene, as demonstrated by scientists at Queen Mary University of London and the Cambridge Graphene ...
