Scientists make transparent materials absorb light

A group of physicists from Russia, Sweden and the U.S. has demonstrated a highly unusual optical effect. They managed to "virtually" absorb light using a material that has no light-absorbing capacity. The research findings, ...

Researchers explore new chapter of physics

Interactions between light and matter are a fundamental unit of modern physics, but recently researchers have started to look beyond the standard textbook interactions.

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.
