Novel perovskite can monitor chemical reactions in real time

A novel perovskite-based nanomaterial changes color when it interacts with ions and other small molecules during a chemical reaction.

Because it changes from a solid state to a liquid state at around 30°C, gallium can make an effective reversible adhesive.

Scientists have discovered that the degradation of perovskite solar cells in sunlight is reduced at low temperatures and reversed in the dark.
