NJC Issue 11 now online

NJC is delighted to present this month’s issue. Whether you are a materials scientist, biologist, physicist or medicinal chemist, you are guaranteed to find articles of relevance to your specialist interests.

The outside front cover highlights our latest article by Yukikazu Takeoka and co-workers. In their Letter article, the authors describe the preparation of an amorphous array composed of thermo-responsive fine core–shell particles in which the core is a monodisperse silica particle and the shell is a high-density polymer brush of uniform thickness made from thermally responsive poly(N-isopropylacrylamide) (PNIPA).  After observing the optical behaviours of the amorphous array, it was found that the position and the strength of the angle-independent PBG from the array can reversibly change depending on the environmental temperature. This system has promising application in light switching, sensors, and displays.

An amorphous array of poly(N-isopropylacrylamide) brush-coated silica particles for thermally tunable angle-independent photonic band gap materials by Yoshie Gotoh, Hiromasa Suzuki, Naomi Kumano, Takahiro Seki, Kiyofumi Katagiri and Yukikazu Takeoka, New J. Chem., 2012,36, 2171-2175, DOI: 10.1039/C2NJ40368D

The inside front cover was produced by Kenta Adachi and co-workers, and highlights a new approach to induce chirality in H-aggregates of achiral methylene blue (MB) dyes by chiral phenylalanine (Phe) molecules. The results demonstrate a chirality transfer and amplification from only the pre-adsorbed Phe molecules to MB aggregates formed on the WO3 colloid surface via non-covalent interactions. These findnings open new promising ways towards the design of efficient chiral supramolecular sensors and devices.

Chirality induction and amplification in methylene blue H-aggregates viaD– and L-phenylalanine pre-adsorbed on the tungsten oxide nanocolloid surface by Kenta Adachi, Shohei Tanaka, Suzuko Yamazaki, Hideaki Takechi, Satoshi Tsukahara and Hitoshi Watarai, New J. Chem., 2012, 36, 2167-2170, DOI: 10.1039/C2NJ40415J

Meet Our Authors – September 2012

Faces behind the research: Learn more about some of our authors and check out their latest entries.

Gilles Gasser is Assistant Professor at the Institute of Inorganic Chemistry, University of Zurich, Switzerland. His current research focuses on two main research topics, namely medicinal inorganic chemistry and inorganic chemical biology. In particular using metal complexes to modify or understand biological processes in living cells. In their NJC paper Gilles and his co-workers describe the full characterization by electrochemistry of two new ferrocene-containing ligands as well as their complexes with five different transition metal ions. Two X-ray structures of CuII complexes were determined, which contain a rare CuII–I2–CuII bridge.

“We felt that our results deserved to be published in an interdisciplinary journal with high visibility. New J. Chem. was therefore the ideal journal to report this work!”

Besides his research activity, Gilles enjoys long-distance running, travelling and hiking in the mountains.

Electrochemical, spectroscopic, magnetic and structural studies of complexes bearing ferrocenyl ligands of N-(3-hydroxypicolinoyl)picolinamide by Gilles Gasser, Cristina Mari, Michelle Burkart, Stephen J. Green, Joan Ribas, Helen Stoeckli-Evans and James H. R. Tucker, New J. Chem., 2012, 36, 1819–1827, DOI: 10.1039/C2NJ40177K

Jens Hasserodt, Professor of Chemistry at the Ecole Normale Superieure de Lyon at the University of Lyon, France. Jens’s research area involves small-molecule probes for molecular and functional imaging of enzymes.

His contribution to this month’s issue is a Focus article that reviews, in the context of the existing literature, his own recent contribution of a magnetogenic probe. This small iron-based coordination compound turns its sample from diamagnetic (off) to paramagnetic (on) upon addition of a specific chemical reactant.

On the main motivation for submitting his work in NJC, Jens comments: “Because of its declared and pursued orientation toward new directions in chemistry.”

Choir singing, biking, mountain hiking, literature and concerts are Jens’ favorite activities outside the lab.

Magnetogenic probes that respond to chemical stimuli in an off–on mode by Jens Hasserodt, New J. Chem., 2012, 36, 1707-1712, DOI: 10.1039/C2NJ40209B

Our last author is Jianguo Huang , who is Professor at the Department of Chemistry, Zhejiang University, China.

His research interests are in the area of functional nanostructured materials based on self-assembly approaches, biomimetic syntheses, and surface chemistry.

In their NJC article, Jianguo Huang and his colleagues demonstrated that self-assembling colloidal particles is a unique pathway to produce functional materials with tailored physical properties. Their work presents a facile self-assembly approach to organize colloidal microspheres into free-standing hollow structured microtubes, which possess considerable potentials for the applications in various areas such as photonic crystal, separation and cellular immunoisolation.

On choosing NJC to publish this work, Jianguo comments: “I have been impressed with the new opinions that can always be found in NJC, and I am very satisfied with the rapid publication process in this journal. I am sure that NJC will be an indispensable journal for the chemists worldwide to seek for new ideas in the coming future.”

In his free time, Jianguo enjoys reading classical literature and history.

How good are the crystallisation methods for co-crystals?

In this NJC Hot paper, Fucke et al. attempt to answer a very important question relating to co-crystal formation and screening. Piroxicam, a non-steroidal anti-inflammatory drug, was chosen as a model system and subjected to extensive co-crystal screening using twenty different acids as co-crystal formers, six crystallisation techniques and five solvents. The work explores in comprehensive detail the use of different techniques for obtaining co-crystals and compares their efficacy. The authors offer several thoughts on how their results might usefully be applied to improve co-crystal screens.

How good are the crystallisation methods for co-crystals? A comparative study of piroxicam by Katharina Fucke, Svetlana A. Myz, Tatyana P. Shakhtshneider, Elena V. Boldyreva and Ulrich J. Griesser; New J. Chem., 2012, Advance Article, DOI: 10.1039/C2NJ40093F, Paper

Meet Our Authors – April 2012

Faces behind the research: Learn more about some of our authors of the April issue of NJC and check out their latest entries.

Prof. Robert Bruce King is Regents’ Professor Emeritus at the University of Georgia, USA. He is currently directing a research program directing collaborators spread over three continents.  He works with large research groups in Romania at Babeş-Bolyai University (Cluj-Napoca) and in China at South China Normal University (Guangzhou) and Xihua University (Chengdu) where he has adjunct academic appointments.

His research interests are computational inorganic and organometallic chemistry. The paper to be published in NJC deals with using density functional theory to explore the chemistry of boronyl (BO) analogous of the simple metal carbonyls.  The work describes the interesting structures of Fe2(BO)2(CO)8 isoelectronic with the well-known dimanganese decacarbonyl.

“This paper is of broad interest to both inorganic and physical chemists, therefore a general journal such as NJC appeared to be the most suitable journal for this paper” commented Prof. King on choosing the NJC journal to publish this work.

When asking which scientific problem he would like to solve: “I am much more oriented towards exploring uncharted territory rather than solving specific problems.  Early in my career, I found the synthesis of new molecules exhibiting novel structural features to be very exciting.  Nowadays, I am particularly enthusiastic about generating new types of molecules in silico on the computer using well-established density functional theory methods arising from quantum chemistry”.

Binuclear iron boronyl carbonyls isoelectronic with the well-known decacarbonyldimanganese by Yu Chang, Qian-Shu Li, Yaoming Xie, R. Bruce King and Henry F. Schaefer III, New J. Chem., DOI: 10.1039/C2NJ20894F


Jana Juan-Alcañiz is a PhD student at the Delft University of Technology in the Netherlands. Jana is working in the field of heterogeneous catalysis and her current research interests are metal-organic frameworks as nanoreactors.

In their NJC paper, Jana and her colleagues focused on “a ship in a bottle” approach that has been followed to successfully encapsulate phosphotungstic acid in the metal-organic framework MIL-100(Cr). The influences of the synthesis conditions, like solvent effect or irradiation methods have been investigated to achieve efficient one-pot encapsulation maintaining the chemical nature of the guest species.

Solving the low efficiency of renewable energy sources is a scientific problem that Jana would like to solve.

Towards efficient polyoxometalate encapsulation in MIL-100(Cr): influence of synthesis conditions by Jana Juan-Alcañiz, Maarten G. Goesten, Enrique V. Ramos-Fernandez, Jorge Gascon and Freek Kapteijn, New J. Chem.DOI: 10.1039/C2NJ20587D

Our next author is Dr. Eliano Diana, an Associate Professor of General and Inorganic Chemistry at Faculty of Sciences M.F.N., University of Turin, Italy. His research interest centers on the evaluation of bond properties and intermolecular interactions in metal complexes by means of vibrational spectroscopies and computational modeling.

Eliano’s contribution to this April issue of NJC reports the experimental data concerning atypical hydrogen bonds found in organometallic salts and tried to explicate it with a multidisciplinary approach.

When asking why did he decide to submit this work to NJC, Eliano answered: ”Because of the good quality of the Journal, the cross-disciplinary spread and the excellent editorial support”.

If Eliano could solve any scientific problem: “I’d eliminate the HIV virus”.

Blue and red shift hydrogen bonds in crystalline cobaltocinium complexes by Eliano Diana, Michele R. Chierotti, Edoardo M. C. Marchese, Gianluca Croce, Marco Milanesio and Pier Luigi Stanghellini, New J. Chem., DOI: 10.1039/C2NJ20760E

Dr. Sébastien FLOQUET holds an Associate Professor position at Institut Lavoisier de Versailles, University of Versailles, France. His research activity is currently concentrated on synthesis and characterization of polyoxo(thio)metalates.

In their NJC paper, Sébastien and his collegues highlight the liquid crystal properties of a famous nanoscale polyoxometalate, i.e. the “Keplerate” compound [Mo132O372(CH3COO)30(H2O)72]42- surrounded by 36 DODA+ cations. “In this field of research, the results we present here opens the route towards the formation of new mesomorphic phases based on very large inorganic clusters simply by ionic association with appropriate organic cations”.

New Journal of Chemistry is a European journal co-edited by RSC and the French CNRS. Futhermore NJC publishes articles focused on all domains of chemistry, the colored figures are free of charge and NJC possesses a good impact factor, which probably will increase in the future” explains why Sébastien and his colleagues consider that their work is particularly suitable for NJC.

“In my opinion, environmental and energetic problems constitute the main challenges for chemists today. The synthesis of highly efficient materials for hydrogen production, CO2 conversion or pollutant reduction are probably the most exciting challenges I would like to solve”.

Evidence of ionic liquid crystal properties for a DODA+ salt of the keplerate [Mo132O372(CH3COO)30(H2O)72]42− by Sébastien Floquet, Emmanuel Terazzi, Akram Hijazi, Laure Guénée, Claude Piguet and Emmanuel Cadot; New J. Chem., DOI: 10.1039/C2NJ20923C

We would like to thank to our authors for answering these questions for us and we appreciate their interest in publishing with us and look forward to seeing new submissions soon!

NJC Poster Prize winner at 10th Ferrocene Colloquium

Many congratulations to Claudia Heindl who was awarded the NJC poster prize at the 10th Ferrocene Colloquium held in Braunschweig, Germany, for her poster entitled Template controlled formation of spherical supramolecules with fullerene-like topology.

Claudia is a PhD student at the University of Regensburg, Germany, in the group of Prof. Dr. Manfred Scheer and her poster dealt with the use of the pentaphosphaferrocene [Cp*Fe(η5-P5)] (Cp* = C5Me5) as a building block between CuX units (X = Cl, Br, I) for the formation of spherical supramolecules with fullerene-like topology.

 “In the first fullerene-like spherical supramolecule containing Cp*FeP5 and CuX (X = Cl, Br) as building blocks there was found a molecule of Cp*FeP5 inside the ball. That led to the question, whether there is a template-effect of the pentaphosphaferrocene. And in fact, adding suitable molecules to the reaction mixture, the incorporation takes place. The perspective for the future is to incorporate especially unstable molecules or generate unstable molecules by cleavage of e.g. triple decker complexes. In addition, these nanoballs can serve as hosts for several templates such as C60 and o-carborane”.

Since Claudia has just started her PhD, the plan for the future concentrates on “a successful time at the University of Regensburg, and after that: Who knows?”

The NJC editorial team wishes to congratulate Claudia Heindl who also receives a one-year subscription to the journal. Our thanks go to the organizers of this conference for their help in organizing this award.

How to improve the performance of carbon nanotubes-glycerol nanofluids

J. Hao et al. (China) report the influence of polyvinyl alcohol on the thermal conductivity and the fluidity (sol-gel transition behavior) of carbon nanotubes-glycerol nanofluids.

carbon nanotubes-glycerol nanofluids

The thermal conductivity, stability, fluidity, and rheological properties were investigated by using various characterization techniques. The additional polyvinyl alcohol could amazingly reduce the viscosity of the nanofluids while the thermal conductivity was mostly maintained, even slightly further increased.

It suggests the as-prepared nanofluids may be applicable in energy transfer systems and thus pushes one step further towards real application of CNT based nanofluids.

A gel–sol transition phenomenon of oxidation multi-walled carbon nanotubes–glycerol nanofluids induced by polyvinyl alcohol by Baogang Wang, Wenjing Lou, Xiaobo Wang and Jingcheng Hao, New J. Chem., 2012, DOI: 10.1039/C2NJ20977B.
