Metalens combined with an artificial muscle

Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens, that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism, and ...

Molecular system for artificial photosynthesis

Photosynthesis in green plants converts solar energy to stored chemical energy by transforming atmospheric carbon dioxide and water into sugar molecules that fuel plant growth. Scientists have been trying to artificially replicate this energy conversion process, with the objective of producing environmentally friendly and sustainable fuels, such as hydrogen and ...

Toward artificial photosynthesis: Mimicking the ingenuity of nature

A clean, climate-friendly energy source that is virtually inexhaustible: This is the promise artificial photosynthesis holds. Chemists from the University of Würzburg have now got one step closer to reaching this goal. The scientists present their work in the journal Nature Chemistry. Nature shows how to do it: Photosynthesis is ...
