(PhysOrg.com) -- The best performing solar cells are those that are thick enough to absorb light from the entire solar spectrum, while the cheapest solar cells are thin ones, since they require less, and potentially cheaper, ...
The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue. These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic ...

(PhysOrg.com) -- Taking light control to a new level, scientists have proposed a technique for confining light into an area just 1/500th the size of the light's wavelength. Since funneling light through such tiny spaces enhances ...
(PhysOrg.com) -- Due to its high data carrying capacity and low loss, light can serve as an ideal information carrier. However, due to the high speed at which it travels, light is difficult to store. Because the ability to ...
