Scientists make transparent materials absorb light

A group of physicists from Russia, Sweden and the U.S. has demonstrated a highly unusual optical effect. They managed to "virtually" absorb light using a material that has no light-absorbing capacity. The research findings, ...

A new type of photonic time crystal gives light a boost

Researchers have developed a way to create photonic time crystals, and they have shown that these bizarre, artificial materials amplify the light that shines on them. These findings, described in a paper in Science Advances, ...

Metamaterial significantly enhances chiral nanoparticle signals

The left hand looks like the right hand in the mirror but the left-handed glove does not fit on the right hand. Chirality refers to this property where the object cannot be superimposed on to the mirror image. This property ...

Light propagation in solar cells made visible

How can light which has been captured in a solar cell be examined in experiments? Jülich scientists have succeeded in looking directly at light propagation within a solar cell by using a trick. The photovoltaics researchers ...

The makings of a crystal flipper

Hokkaido University scientists have fabricated a crystal that autonomously flips back and forth while changing its flipping patterns in response to lighting conditions. Their findings, published in a Chemistry Europe's journal, ...
