Scientists have demonstrated how to manipulate light by using time-varying media in the form of specialized nanomaterials.

Some beetles, such as Anomala albopilosa, strongly reflect left circularly polarized light (electromagnetic waves that oscillate leftward relative to the direction of light reception). This property ...

Now, researchers have developed a new nanomaterial called nanoPE for street lights. This nanomaterial fulfills two key roles: efficient heat removal and enhanced light output. Moreover, these ...

Wearing reflective materials helps other people to see you in the dark; however, they will only work when a source of light - such as a torch, lamp or candle - reflects off them. Students could ...

materials. Transparent substances ... but they can be seen because they reflect light from luminous objects. The light travels in a straight line directly from the object to your eye.
