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 ...

The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought their efficacy is limited to absorbing only half of the incidental light at ...

Did you know that things that glow in the dark are called 'phosphorescent materials'? These absorb light energy and release ...

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 ...

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 ...

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 ...

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 ...

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 ...
