When is a hole not a hole? Researchers investigate the mystery of 'latent pores'

Researchers have explored how a particular chemical can selectively trap certain molecules in the cavities of its structure—even though in normal conditions it has no such cavities. This innovative material with now-you-see-them-now-you-don't ...

A definitive atomic structure of the heme crystals made by malaria parasites could lead to better antimalarial drugs

Prof. Leslie Leiserowitz first became intrigued by malaria when he was a young boy in South Africa. His father, who scouted the continent in search of wood for the family business, brought back not only tales of elephants ...

Engineering perovskite materials at the atomic level paves way for new lasers, LEDs

Researchers have developed and demonstrated a technique that allows them to engineer a class of materials called layered hybrid perovskites (LHPs) down to the atomic level, which dictates precisely how the materials convert ...

Exploring the structures of xenon-containing crystallites

Noble gases have a reputation for being unreactive, inert elements, but more than 60 years ago Neil Bartlett demonstrated the first way to bond xenon. He created XePtF6, an orange-yellow solid. Because it's difficult to grow ...

PhAI—an AI system that figures out the phase of x-rays that crystals have diffracted

A trio of chemists at the University of Copenhagen has developed an AI application that can be used to figure out the phase of x-rays that crystals have diffracted as part of efforts to predict the structure of small molecules.
