Twisted moiré photonic crystals—an advanced type of optical metamaterial—have shown enormous potential in the race to engineer smaller, more capable and more powerful optical systems. How do they work ...

LLNL researchers are pioneering a coaxial DIW method for 3D printing cholesteric liquid crystal elastomers (CLCEs).

Capturing precise 3D details with a single camera has long been a challenge. Traditional methods often require complex ...
