Nanodiamonds are tiny diamond particles only a few nanometers in size. Because they are chemically highly stable and can host so-called color centers, optically active defects in the crystal lattice, they are considered promising materials for quantum technologies, sensing and biomedical research. Until now, however, it has been difficult to reliably produce nanodiamonds with uniform size, high purity and precisely integrated optical properties.

Whisky-inspired chemicals could help power a new generation of microscopic machines, according to researchers who have discovered a way to make tiny particles "swim" through liquid using compounds linked to the production of Scotland's national drink.

Cornell researchers have developed a new way to create moiré patterns—atomic-scale structures that can give materials unusual quantum behaviors—without relying on the traditionally used difficult-to-control twisting and stacking methods. The study is published in the Proceedings of the National Academy of Sciences.
