The design and functions of liquid-crystalline (LC) polymers with classifying them into conventional-, supramolecular-, dendritic- and network-type LC polymers are described. LC polymers show new ...

Photonic crystals are periodic optical structures that can control the flow of light. Multiple reflections from surfaces separated by a distance similar to the wavelength prevent an optical beam from ...

Scientists have observed an extraordinary quantum phenomenon inside tiny semiconductor crystals, revealing a synchronized ...
