Tin-based perovskite solar cells can hold on to hot electrons

A new tin-based perovskite solar cell allows 'hot' electrons to retain their high energy levels for longer than usual, which could help produce more power.

New 3D printing process can control fiber orientation in composites

A novel 3D printing method can yield unprecedented control over the arrangement of short fibers embedded in polymer matrices.

Researchers have found a way to produce a two-dimensional electron gas between insulating oxides on the semiconductor gallium arsenide.

By conducting systematic studies, researchers have provided a quantitative picture of how surface conditions control the growth of metal nanocrystals.

Researchers have developed the first single metalens able to focus the entire visible spectrum of light in the same spot and in high resolution.

The transfer of energy from nanomaterials to molecules can go both ways, causing the nanomaterials to photoluminesce over long timescales.

Quantum effects allow samarium nickelate to mimic a shark's sixth sense, by detecting minute electric fields in salt water.
