Astatine halogen bond finally revealed!
Astatine is the last member of the halogen family, which also includes fluorine and chlorine. These chemical elements have a distinct feature: they are able to form an unusual kind of bond with molecules. Yet for astatine, the existence of this specific halogen bond had never before been proven. This is because in its natural state, astatine is the rarest …

In the world of materials, composites are currently undergoing a transformation that is just a significant as the plastics boom in the 1960s. To massively integrate these materials into high-volume production markets—automotive, aeronautics, rail, etc.—manufacturers must further reduce the time it takes to mold the parts. This complex goal is attainable by redesigning the materials’ composition and architecture, adapting the …
