Blue light-emitting diodes (LEDs) are needed for high-definition displays with wide colour range. Efficient, stable and colour-saturated blue LEDs containing emitters made of perovskites have now been fabricated by adding isomeric molecules that generate a network of hydrogen bonds, stabilizing the octahedral structure of the perovskite crystal.

Cell-type signatures of Alzheimer’s disease shared across population groups

A database of daily dust metals in Europe is established and a machine learning model shows that transported dust intrusion events over the past decade are linked to changes in atmospheric circulation, while an ice core shows that the increase in dust since pre-industrial times is governed by increasing aridity in North Africa..
