NJC Editor-in-Chief Wais Hosseini wins Joseph-Achille Le Bel Award

Editor-in-Chief Professor Mir Wais Hosseini is one of two recipients of the the Grand Prix Joseph-Achille Le Bel Award, 2016 in recognition of his remarkable discoveries in supramolecular chemistry. The prize is awarded annually and recognises French chemists whose work have achieved international acclaim.

After starting his scientific career under the direction of Jean-Marie Lehn, Professor Hosseini created his own laboratory and focussed his research towards molecular tectonics’ which corresponds to large-scale (millimeter) molecular architectures in the solid state by self-assembling “tectons”. The formation of these non-covalent assemblages involves three types of interactions: coordination bonds, combinations of directional hydrogen bonds and electrostatic interactions, and van der Waals interactions. Their structure can be controlled and programmed according to one, two or even three dimensions by coding information at the tecton level.

His work has brought a major breakthrough in the field of supramolecular chemistry and the study of self-assembly processes as well developing compounds that can be regarded as a new generation of coordination polymers in the crystalline state. His work on “molecular tectonics” has been carried out for more than twenty years in his laboratory and has resulted in an international recognition of his team.

Professor Hosseini has also been the recipient of the CWS Organic Chemistry and Co-ordination Chemistry Prizes and the CNRS Silver Medal in 2011. His international recognition was rewarded by the European Academy of Sciences in 2004 and by the Academia Europaea in 2006.

The NJC Editorial office sends its congratulations to Professor Hosseini on receiving this prestigious award.

Blue nanoparticles mop up radioactive element

Scientists in France have developed a nanoparticle-based formulation of Prussian blue, which could lead to better treatments for people who have been exposed to radioactive contamination.

Large quantities of radioactive contaminants can be released into the environment during nuclear weapon tests or accidents at nuclear reactors – such as those that occurred in Chernobyl, Ukraine, in 1986, and more recently in Fukushima, Japan. Radioactive caesium isotopes are among the more common fission products that escape during such events and are easily absorbed by the human body. Exposure to radioactive caesium can cause many different types of cancer, neurological effects and in extreme cases rapid death.

The full story can be read in Chemistry World.
