“We’ve achieved a luminescent concentration ratio greater than 30 with an optical efficiency of 82-percent for blue photons,” says Berkeley Lab director Paul Alivisatos, who is also the Samsung ...

(Nanowerk News) The ability of metallic or semiconducting materials to absorb, reflect and act upon light is of primary importance to scientists developing optoelectronics – electronic devices that ...

Just when scientists thought they knew everything about crystals, a Northwestern University and University of Wisconsin-Madison collaboration has uncovered a hidden secret. Centrosymmetric crystals ...

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 ...

use the invention process to design, build, and test a solar cooker. describe how transmission, absorption, and reflection are used in a solar cooker to heat water. evaluate what variables contribute ...

Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take ...

The filter is an indispensable optical component in photography, which can change the spectral intensity distribution of the incident light or change its polarization state according to the ...

There's black, and then there's super-black. A new super-black wood-based material has been created that absorbs more than 99 percent of the light that hits it. What's more, the material was ...
