Light has healing effect on perovskite films

Scientists have found that certain defects in perovskite films can be healed by illuminating the films with intense light.

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

Sandwiching graphene between two layers of boron nitride produces a 'superlattice' that allows a single photon to excite multiple electrons.

A new technique for depositing diamond on the surface of cubic boron nitride can integrate the two materials into a single crystalline structure.

Scientists have enhanced the photoluminescence efficiency of tungsten diselenide, a 2D semiconductor, by incorporating it on nanosized gold trenches.

Researchers have developed microporous polymer membranes that can accurately separate molecules at a high processing rate.

Using tiny vesicles and liquid crystals, scientists have produced a synthetic model of a cell membrane.
