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.

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.

NJC Nov 16 IFC - Dr Jelinek

The inside cover is proposed by Dr Raz Jelinek (Ben Gurion University of the Negev, Israel). According to Dr Jelinek and his co-workers, the analysis of artworks and identification of their molecular components is very important to choose proper conservation strategies and monitor their restoration. In their study the authors present an application of spin-coated polydiacetylene films for in situ colorimetric sensing of a selection of organic materials present in paintings. Their study shows that the polydiacetylene technology might open new analytical avenues in molecular analysis, in general, and more specifically for painting restoration and conversation science.

NJC FOC Nov 16 - Dr Labarca

Also read the short Focus review by Dr Martín Labarca (Universidad de Buenos Aires, Argentina). Dr Labarca addresses the problem of the status of the element of atomic number zero or “neutronium”. According to him, it is more cautious from both a scientific and a philosophical standpoint, to think of the neutron just as a structural component of an element.

An element of atomic number zero?

NJC issue 10 now online

NJC Oct 2016 OFC - Prof. HanusaThe October outside cover is proposed by Prof. Timothy P. Hanusa (Vanderbilt University, USA). In this article, the authors report a series of heavy alkaline-earth iodide coordination compounds containing various neutral donor ligands: phosphine oxides, ureas and the nitrobenzene dimer. These donors were chosen for their range of basicity and steric demand, to determine how well they could compete with the iodide ligand. The observed reactivity patterns suggest that ureas deserve more widespread use in group 2 chemistry, as they have a basicity that exceeds that of phosphine oxides, are available with a variety of substituents, and are inexpensive.

NJC issue 09 now online

NJC OFC Sept 2016 - Dr GuoThis month, the outside cover is proposed by Dr Jinbao Guo (Beijing University of Chemical Technology, China). In their work, the authors develop a facile bilayered structural device composed of a silver nanoparticle array with a liquid crystal elastomer. The device is elastic and changes color by sensing deformations induced by changing temperature, attributed to alignment of the liquid crystal molecules induced by the nanoparticle array. This actuator design could be a promising candidate for smart environmental-responsive devices such as thermal-camouflage skin and color-changing actuators.

NJC OFC Sept 2016 - Dr Mazej

Miss Maruša Mazej designed the inside cover to illustrate a study by Dr Zoran Mazej and his colleague Dr Goreshnik (Jožef Stefan Institute, Slovenia). Based on a short communication published in 1976 presenting three compounds described as XeF6·TiF4, 4XeF6·TiF4 and XeF6·2TiF4, and on the synthesis of [XeF5]3[Ti4F19] (i.e. 3XeF6·4TiF4) published in 2009, the authors reveal in this study the crystal structures of these 3 compounds, which can be formulated as XeF5TiF5, [XeF5]5[Ti10F45] and [XeF5][Ti3F13]. [XeF5]5[Ti10F45] contains the largest known discrete decameric [Ti10F45]5− anion built from ten TiF6 octahedra that share vertices and that are arranged in a double-star shape.

NJC Poster Prize Winners at Metals and Genetics Meeting

Three young scientists were recognized for their contributions at the 6th International Conference on Metals and Genetics, which took place earlier this year at the Indian Institute of Science in Bangalore.

The winners (in no particular order) of the NJC Poster Prizes awarded at this conference were:

Mr Vadde Ramu, National Chemical Laboratory, Pune
Poster title: New imaging reagents for lipid dense regions in live cells and the nucleus in fixed MCF-7 cells

The presented work is part of Vadde’s Ph.D. thesis, carried out under the supervision of Dr. Amitava Das. Vadde will be defending his thesis work this month and is moving to Jena for a post-doctoral position in October.

The presented research work demonstrated the design and synthesis of two new uracil (U) and 5-flurouracil (5-FU) labelled ruthenium(II)-polypyridyl based cellular imaging reagents. These two complexes were found to show affinity towards DNA in the nucleus of the PFA fixed cells. A large Stokes shift (λ = 160 nm) and an appreciably long-lived 3MLCT excited state (λ = 320 ns) in aq. buffer medium (pH 7.4) are other key features of these complexes. Unlike the common nuclear DNA staining reagents like DAPI, these low-cytotoxic reagents are found to be highly stable towards photo-bleaching upon irradiation with λ > 455 nm at the MLCT band for these complexes.

Mr Samsuzzoha Mondal, Tata Institute of Fundamental Research, Mumbai
Poster title: Sensing Signalling Phospholipids with ‘Lanthano-proteins’

Samsuzzoha is a Ph.D. student working in the group of Dr. Ankona Datta. He is in his final year and expects to defend his degree in mid-2017.

His present research is about developing fluorescent probes for imaging the crucial phospholipids involved in cell signaling processes. Currently available genetically encoded fluorescent probes lack ‘on-off’ sensing and have problems with background signal. Hence tracking the spatio-temporal dynamics of phospholipids in a live cellular process with those fluorescent proteins is challenging. The authors are addressing this issue by developing novel fluorescent probes with ‘turn on’ or ‘ratiometric’ fluorescence sensing. The poster presents a ‘lanthano’-protein based ‘turn on’ sensor for phosphatidylserine, a phospholipid involved in cell-death signals mediation and several other signaling processes. Additionally, a recently developed, cell permeable, ratiometric sensor for phosphoinositides, the most important signaling phospholipids in the cellular system, is demonstrated.


Ms Tandrila Das, Indian Institute of Science, Bangalore
Poster title: Vacancy-Engineered Nanoceria: Enzyme Mimetic Hotspots for the degradation of Nerve Agents

Tandrila did the work presented in the poster as a 5th year BS-MS student under the direction of Prof. Govindasamy Mugesh. She is now a 1st year student in the Tri-Institutional Ph.D. program in chemical biology offered by Weill Cornell Medicine, Memorial Sloan-Kettering Cancer Center and The Rockefeller University (all located in New York City).

The study of phosphotriesterase (PTE) enzymes and synthesis of its structural and functional mimics has been a long time interest of the lab. PTE enzymes degrade organophosphorus nerve agents, which are known to inhibit acetylcholine esterase, thus resulting in paralysis, respiratory failure, etc.  For her Master’s thesis, Tandrila worked on developing a nano-mimic of PTE enzyme. The poster work showed that vacancy engineered nanoceria (CeO2) with Ce in both +3 and +4 oxidation states very efficiently act as a catalyst to hydrolyze organophosphorus nerve agents like paraoxon, parathion, etc.

(The photo shows Tandrila on the left with co-author Dr Amit Vernekar, currently a post-doc in the Lippard group at MIT.)

Congratulations to the 3 laureates, and best wishes for continuing success in their research and careers.

NJC issue 08 now online

NJC August 2016 OFC - L. SmolkoLukáš Smolko in the group of Prof. Juraj Černák (P. J Šafárik University in Košice, Slovakia) designed this month’s outside cover. In their article, the five authors report on a novel series of tetracoordinate Co(II) complexes— [Co(bcp)X2] (bcp = bathocuproine; X = Cl, Br, I)—which all possess moderate magnetic anisotropy. They show that although the structures of the complexes are very similar, slight differences in the crystal packing lead to significantly different magnetic behaviour.

NJC August 2016 IFC - L. Henderson

The inside cover is proposed by Dr Luke Henderson (Deakin University, Australia) to illustrate a study in which the authors examine the toxicity of a new class of ionic liquids. These are equimolar solutions of lithium bistrifluoromethylsulfonimide in triglyme (G3TFSA) or tetraglyme (G4TFSA), with potential applications in a variety of areas such as energy storage in lithium batteries and as  alternatives to traditional organic solvents. The authors demonstrate the lack of toxicity of these two solvate ionic liquids by three different complementary methods and conclude that G3TFSA and G4TFSA can be used as a replacement for DMSO for experimental research both in vitro and in vivo.
