However, they can be programmed with a variety of gradient index (GRIN) structures including diffractive and refractive lenses. The polymers self develop in respnse to light, enabling complex 3D GRIN ...

The bifocal lenses are made from bilayer structures of liquid crystal (LC) cells and LC polymer. These lenses split light with a left-handed circular polarization (LCP) into two focused light ...

Imagine a microscopic locomotive moving back and forth along a track, propelling itself without any external force. At the molecular level, this concept forms the foundation of molecular motors -- ...
