Imagine life in a ‘clean house gas’ rather than a ‘green house gas’ world; this will require a change of human behavior from that practiced in the Anthropocene era where the Earth’s ecosystems have been negatively impacted by humans to the Sustanocene age where humans strive to heal the Earth through renewable technologies to make things better.

A NIST team has created an ultraviolet (UV) metamaterial formed of alternating nanolayers of silver (green) and titanium dioxide (blue). The metamaterial has an angle-independent negative refractive index, enabling it to act as a flat lens. When illuminated with UV light (purple) a sample object of any shape placed on the flat slab of metamaterial is projected as a three-dimensional image in free space on the other side of the slab. Here a ring-shaped opening in an opaque sheet on the left of the slab is replicated in light on the right. Bottom left: Scanning electron micrograph of a ring-shaped opening in a chromium sheet located on the surface of a flat slab of metamaterial. Bottom right: Optical micrograph of the image projected beyond the slab under UV illumination, demonstrating that the metamaterial slab acts as a flat lens. Image: Lezec/NIST.

Metamaterial flat lens is recording breaking

New type of lens bends and focuses ultraviolet light in such an unusual way that it can create ghostly, 3D images of objects that float in free space.

This illustration shows a lead sulfide quantum dot array. Each quantum dot (the colored clusters) is 'passivated' by molecules that bind to its surface. Dots that are made up of unequal amounts of lead and sulfur tend to cause electrons (shown in red) to become highly localized, which can substantially lower the electrical transport of the device. Image: Donghun Kim and Jeffrey C. Grossman.

A step towards QD solar cells

MIT researchers find that the secret lies in off-kilter ratios of the two basic components that make up the dots.
