Researchers at UNSW Sydney have developed a nanoscale device that converts low-energy infrared and red light into higher-energy visible light, a breakthrough that could eventually improve solar panels ...

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 ...

Controlling a molecule is not always simple. For instance, the precise arrangement of electrons in an organic molecule determines the wavelengths of light it can absorb; this can be challenging to ...

New research reveals the core structure of the light-harvesting antenna of cyanobacteria or blue-green algae -- including key features that both collect energy and block excess light absorption.

How do photosynthetic organisms harvest light so efficiently? To help answer this question, researchers have developed an ultrafast transient absorption microscope with sensitivity approaching the ...
