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

Infection sensor for wound dressings

Scientists in Australia have developed an optical sensor to be used in wound dressings that signals when a patient’s wound is inflamed or infected.

The sensor, made from polymer-grafted porous silicon, detects a small increase in temperature, which is a classic indication of wound infection. Early diagnosis of infection could be achieved by monitoring the reflectance spectrum of the sensor.

Above a critical temperature value, the polymer changes from a hydrophilic coil to a hydrophobic globule, resulting in changes in its optical properties which are detected by reflectance spectroscopy.

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.

Facile fabrication of free-standing microtubes composed of colloidal spheres by Xiaoyan Liu and Jianguo Huang, New J. Chem., 2012, 36, 1729-1732, DOI: 10.1039/C2NJ40486A

October issue of NJC out now!

We are pleased to introduce you to our latest issue. Whether you are a material, synthetic or biological chemist, you are guaranteed to find articles of relevance to your specialist interests.

The outside front cover highlights a paper by Katharina Fucke and co-workers (University of Durham, UK) and collaborators, reporting a comparative study of co-crystallisation methods for obtaining new co-crystal forms of a model drug compound with twenty different carboxylic acids. A total of 46 co-crystal forms of Piroxicam, a non-steroidal anti-inflammatory drug, were obtained. The authors offer several thoughts on how their results might usefully be applied to co-crystal screens in order to improve the solubility and/or dissolution rate of pharmaceutical drugs.

“How good are the crystallisation methods for co-crystals? A comparative study of piroxicam”, Katharina Fucke, Svetlana A. Myz, Tatyana P. Shakhtshneider, Elena V. Boldyreva and Ulrich J. Griesser New J. Chem., 2012, 36, 1969-1977, DOI: 10.1039/C2NJ40093F.


The inside front cover was produced by Marian R. Davolos and co-workers (Universidade Estadual Paulista, Araraquara, Brazil). In this paper, the authors describe the synthesis and characterization of the amphiphilic europium complex [(C12H25)2(CH3)2N][Eu(tta)4], along with the formation of stable Langmuir monolayers at the air/water interface. The molecular arrangement at the air/water interface and the preserved luminescence in the Langmuir–Blodgett films were consistent with theoretical predictions. This luminescent and amphiphilic complex could be used as a probe when incorporated in Langmuir monolayers of phospholipids or other surfactants that mimic cell membranes.

“Synthesis of a functionalized europium complex and deposition of luminescent Langmuir–Blodgett (LB) films”, Renata D. Adati, Felippe J. Pavinatto, Jorge H. S. K. Monteiro, Marian R. Davolos, Miguel Jafelicci and Osvaldo N. Oliveira New J. Chem., 2012, 36, 1978-1984, DOI: 10.1039/C2NJ40199A
