SYNTHETIC ion-exchange resins of the sulphonated polystyrene type consist essentially of a cross-linked hydrocarbon skeleton to which the functional groups (nuclear sulphonic acid residues) are ...

Molecular Sieves The zeolite minerals, whose crystals contain a myriad of minute pores, have made possible a new branch of chemical technology. They can perform precise separations of very similar ...

Aluminophosphate (AlPO) molecular sieves (MSs) are crystalline microporous materials made from alternating PO 4 tetrahedra ...

In an article published in the journal Angewandte Chemie International Edition, chemists from Heinrich Heine University Düsseldorf (HHU) present an innovative molecular sieve made of partially ...
