Cheaper and easier to manufacture LEDs from perovskite

A hybrid form of perovskite - the same type of material which has recently been found to make highly efficient solar cells that could one day replace silicon - has been used to make low-cost, easily manufactured LEDs, potentially opening up a wide range of commercial applications in future, such as flexible colour displays.

The perfect atom sandwich requires an extra layer

Like the perfect sandwich, a perfectly engineered thin film for electronics requires not only the right ingredients, but also just the right thickness of each ingredient in the desired order, down to individual layers of atoms. Researchers have discovered that sometimes, layer-by-layer atomic assembly requires some unconventional 'sandwich making' techniques.

Bottling up sound waves

Researchers have developed a technique for generating acoustic bottles in open air that can bend the paths of sound waves along prescribed convex trajectories. These self-bending bottle beams hold promise for ultrasonic imaging and therapy, and acoustic cloaking, levitation and particle manipulation.

Self-assembly of gold nanoparticles into small clusters

Scientists have made an astonishing observation: they were investigating the formation of gold nanoparticles in a solvent and observed that the nanoparticles had not distributed themselves uniformly, but instead were self-assembled into small clusters.
