Efficient light conversion with perovskite nanocrystals

Perovskites are a family of crystals that show promising properties for applications in nanotechnology. However, a property called carrier multiplication, an effect that makes materials much more efficient in converting light ...

Saudi Arabia opens high-speed railway to public

Saudi Arabia's new high-speed railway opened to the public on Thursday, whisking Muslim pilgrims and other travellers between Mecca and Medina, Islam's holiest cities.

Self-healing material can build itself from carbon in the air

A material designed by MIT chemical engineers can react with carbon dioxide from the air, to grow, strengthen, and even repair itself. The polymer, which might someday be used as construction or repair material or for protective ...

GeoSEA array records sliding of Mount Etna's southeastern flank

The southeast flank of Mount Etna slowly slides toward the sea. A team of scientists from GEOMAR and the Kiel University have showed for the first time the movement of Etna's underwater flank using a new, sound-based geodetic ...

Simple fabrication of full-color perovskite LEDs

A next-generation optical material based on perovskite nanoparticles can achieve vivid colors even on very large screens. Due to their high color purity and low cost advantages, it has also gained much interests in industry. ...
