Researchers devise new tool to measure polarization of light

Researchers have developed a new tool for detecting and measuring the polarization of light based on a single spatial sampling of the light, rather than the multiple samples required by previous technologies.

Natural photosynthesis with artificial molecules

Chemists have come one step closer to generating energy from sunlight: for the first time, they were able to reproduce one of the crucial phases of natural photosynthesis with artificial molecules.

Flower power: Photovoltaic cells replicate rose petals

With a surface resembling that of plants, solar cells improve light-harvesting and thus generate more power.
