The marketed crystalline form of the painkiller celecoxib (Cel-III), COX-2 selective anti-inflammatory drug, has poor solubility. Various strategies to improve this and increase its bioavailability have been published including the use of crystalline forms of the sodium salt. This study by Julius Remenar and colleagues in the USA describes the structural findings and insights that have resulted from their effort to harness and understand the sodium salts of Celecoxib.

Michael Zaworotko and colleagues from the University of South Florida demonstrate how a tetracarboxylic acid (BIPA-TC) is prepared using C3S3 and then used as a ligand to generate two isomeric nets that represent examples of “ligand-to-ligand” pillaring.

A team at New York University have revealed the importance of chemical interactions at the nucleation surface compared with the periodic surface potential associated with epitaxy in controlling polymorphism through epitaxial relationships with crystalline substrates. In this communication, Brian Olmsted and Michael Ward test the effectiveness of GRACE (Geometric Real-space Analysis of Crystal Epitaxy) software in predicting cases of epitaxially directed nucleation by performing a combinatorial crystallization study involving crystalline substrates and polymorphic compounds.

Industrial wastewater containing toxic metal ions and organic pollutants has become a serious threat to the environment and public health. So the synthesis of three-dimensional micro and nanomaterials with the capability of absorbing undesired water contaminants in a straightforward and effective manner is a priority for environmental scientists.
Now Hongjie Zhang and colleagues at Changhun Institute of Applied Chemistry, have designed an easy method to synthesise flower-shaped Fe3O4 microspheres with magnetic properties, which can be used as absorbents to treat wastewater. Unlike previous synthetic routes, Zhang’s hydrothermal method avoids the use of surfactants and copolymers that would need to be removed from solution.
