A research group led by Associate Professor Masahito Murai of the Graduate School of Science and Professor Shigehiro Yamaguchi of the Functional Organic Materials Laboratory has successfully developed ...

Perfect absorption (PA) of incident light is important for both fundamental light-matter interaction studies and practical device applications. PA studies so far have mainly used resonant ...

Sunlight reflected by solar cells is lost as unused energy. The wings of the butterfly Pachliopta aristolochiae are drilled by nanostructures (nanoholes) that help absorbing light over a wide spectrum ...

Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers ...

Lead is a naturally-occurring element. It has been known to man for a long time, and it is one of the longest established poisons. Strangely enough, even though awareness existed of its toxic effects, ...
