Scientists created the nanocrystal system by coating a silicon surface with a polymer containing chemical groups to which the perovskite nanocrystals would attach. This system provided the researchers with a useful case study for looking at how excitons move, or diffuse, in depth.
Researchers have developed 'nanojars' that split bicarbonate into carbonate and capture it, as well as certain toxic anions, so the ions can be removed and potentially recycled.
In the search for sustainable energy storage, researchers present a new concept to fabricate high-performance electrode materials for sodium batteries. It is based on a novel type of graphene to store one of the world's most common and cheap metal ions - sodium.
