A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen ...

Rare earth elements are essential for modern technology, but their similar chemistry makes separation difficult and expensive ...

(Nanowerk Spotlight) The petrochemical industry relies on separating chemicals that differ by just fractions of a nanometer in size. Methanol must be purified from similarly-sized molecules in the ...

A method to separate two rare earth elements -- europium and yttrium -- with UV light instead of with traditional solvents has been revealed by researchers. Their findings offer new opportunities for ...

(Nanowerk News) Chemical engineers at Ecole Polytechnique Federale de Lausanne (EPFL) have demonstrated for the first time that an atom-thick graphene membrane can separate gas mixtures with a ...

A team of researchers at Penn State have developed a plant-based nanomaterial capable of selectively extracting dysprosium from rare earth mixtures, according to a recent report. The findings ...
