Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

To survive in areas where it is difficult to photosynthesize, some organisms adopt unique strategies. Osaka Metropolitan ...

The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought ...

Scientists from the Leibniz Institute of Photonic Technology (Leibniz IPHT) and the Universities of Jena and Ulm have shown that the properties of special iron compounds that absorb light can be ...

Researchers are reporting progress on the road to more efficient utilization of solar energy: They have developed an innovative light-harvesting system. In order to convert sunlight into electricity ...

A research team has enhanced the titanium oxo clusters’ capacity to absorb solar energy. Their work demonstrates a successful method for modifying the behaviors of these clusters in terms of light ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

Researchers have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic metasurfaces, can absorb light ...

VANCOUVER, British Columbia — Recently, University of British Columbia (UBC) scientists discovered a super-black material that absorbs 99% of light. The new material, which is composed of wood, could ...

It's not convincing to me either. Munroe is correct about etendue, of course, so that the best a lens can do is equivalent to having the object of focus be surrounded by the light source. But that ...
