Using nature to produce a revolutionary optical material

An international team of researchers has reported a new way to safeguard drones, surveillance cameras and other equipment against laser attacks, which can disable or destroy the equipment. The capability is known as optical ...

New record in lead-free halide double perovskites

Illumination consumes more than 20 percent of electricity. Thus, finding an efficient, stable, single-phase warm white-light material is very important. Lead hybrid perovskites have drawn interest for excellent photoelectric ...

A novel synchrotron technique for studying diffusion in solids

Understanding and controlling how the diffusion process works at the atomic scale is an important question in the synthesis of materials. For nanoparticles, the stability, size, structure, composition, and atomic ordering ...

Formation of honeycomb nanostructures finally explained

A few years ago, a promising new type of nanomaterial was observed experimentally, combining the virtues of semiconductors with those of graphene. The material is formed by nanocrystals that spontaneously assemble into a ...

Nanocrystals get better when they double up with MOFs

Out of the box, crystalline MOFs (metal-organic frameworks) look like ordinary salt crystals. But MOFs are anything but ordinary crystals – deep within each crystalline "grain" lies an intricate network of thin, molecular ...

Hairy nanotechnology provides green anti-scaling solution

A new type of cellulose nanoparticle, invented by McGill University researchers, is at the heart of a more effective and less environmentally damaging solution to one of the biggest challenges facing water-based industries: ...
