Toward practical laser-driven light sails using photonic crystals

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored light sails as an alternative. ...

Intermediate phases unlock faster nanoparticle crystallization

Crystalline nanomaterials are valuable because their highly ordered structures give them useful properties for technologies such as data storage and optical devices. But forming nanoparticles from those orderly crystals is ...

A new, useful absorption limit for ultra-thin films

Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at most half of the incident ...
