The direction in which the electromagnetic field of circularly polarized light rotates can be easily reversed by applying a ...

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked ...

In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

Single crystals of potassium europium nitrate, K₃[Eu₂(NO₃)₉], grown from water by slow evaporation (a). Single-crystal X-ray diffraction reveals left- and right-handed chiral crystal structures (c, d) ...

Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

A research group has developed an innovative approach to creating anti-counterfeiting labels for high-value goods. Their findings enhance the security of the currently used cholesteric liquid crystals ...
