Photonic crystal structures have excellent light control properties and are hot topics in the field of photonics. For the preparation of photonic crystal structures with nanoscale three-dimensional spatial resolution inside the crystal, new femtosecond laser processing technologies are urgently needed.

Buried Ancient Roman Glass Formed Substance with Modern Applications
Researchers discover how molecules in ancient glass rearrange and recombine with minerals over centuries to form a patina of photonic crystals – ordered arrangements of atoms that filter and reflect light in very specific ways – an analog of materials used in communications, lasers and solar cells
Gorgeous rainbow-colored, stretchy film for distinguishing sugars (video)
Researchers in ACS Nano report a kaleidoscope-like film for telling different sweeteners apart that displayed multiple colors when stretched by hand. When evenly stretched with a simple apparatus, the material enhanced the unique shifts in fluorescence intensity of 14 sugars tagged with a dye.
Researchers Make Gemstones with Salty, Soapy Water for the First Time
Collaborators from the University of California San Diego and New York University (NYU) used salt, soap and water to make “bling” with a proposed novel experiment by UC San Diego’s Jérémie Palacci to form ionic colloidal crystals from common colloids.
