Hot article: A supramolecular complex with temperature-dependent antioxidative capacity.

Scientists in China have designed and synthesized copolymer as the host and adamantyl fullerene as the guest to construct a host-guest supramolecular complex

Their work shows that the morphology of assemblies formed by the supramolecular complex can alter reversibly from vesicles to nano-spheres by the change of temperature in aqueous solution.

Due to the C60 moiety, the supramolecular complex shows excellent ability to scavenge hydroxyl radicals of biological system.

Thus, the combination of these two effects leads to the possibility of modulating the antioxidative properties of the supramolecular complex via the temperature.

Hot Article : Enzyme activity enhancement through immobilization onto Periodic Mesoporous Organosilicas

In this NJC “Hot Article”, Jian Hua Zhu and co-workers at Nanjing University (China) describe the immobilization of Horseradish peroxidase (HRP) on periodic mesoporous organosilicas (PMO).

It is demonstrated that the enzyme activity is enhanced 110% compared with free HRP in solution. Besides, the stability of immobilized HRP to lower pH values or the denaturing agent urea is enhanced, resulting from interfacial activation of the enzyme when it is attached to a surface filled with organic groups and hydrophobic parts. The thermal stability of immobilized HRP on PMO is also increased and, moreover, the HRP immobilized samples can be reusable for many cycles.

Take time to have a look at it now ! Highly rated by the reviewers and the editorial office, this “Hot Article” will be FREE to access for a period of 4 weeks.

Pt and Pd dendrimer-encapsulated nanoparticles prepared by galvanic exchange

Crooks and co-workers (University of Texas, USA) report the synthesis and characterization of Pt and Pd dendrimer-encapsulated nanoparticles (DENs) using the method of galvanic exchange. In the presence of either PtCl42− or PdCl42−, the less noble Cu DENs oxidize to Cu2+ leaving behind an equal-sized DEN of Pt or Pd, respectively. This methodology is shown to be much faster and giving higher yields than using the common synthetic route i.e. direct reduction with BH4.Equally important, the detailed characterization presented demonstrates that the structure and composition of Pt and Pd DENs synthesized by direct BH4 reduction and galvanic exchange are indistinguishable.

Meet Our Authors, May 2011

We are pleased to present a selection of our authors of the May issue of NJC. We thank each of them for accepting our invitation and having kindly taken some of their time to answer a few questions for us.

Our first author is Dr. Cecilia Devi Wilfred who is Associate Professor at the Universiti Teknologi PETRONAS (Perak, Malaysia). Her current research interests are mainly focused on Ionic Liquids and their applications. In her NJC paper, Cecilia and co-workers report on the synthesis of low densities phosphonate-based nitrile ionic liquids.

The high reputation of the journal which is peer-reviewed to the highest standards was Cecilia’s motivation behind her submission to the journal.

Outside of the lab, Cecilia enjoys reading.

Effect of sulfonate-based anions on the physicochemical properties of 1-alkyl-3-propanenitrile imidazolium ionic liquids by Abobakr Khidir Ziyada, Mohamad Azmi Bustam, Thanapalan Murugesan and Cecilia Devi Wilfred, New J. Chem., 2011, 35, 1111-1116; DOI: 10.1039/C0NJ00950D.

Our next author is George E. Kostakis, Researcher at the Karlsruhe Institute of Technology (Karlsruhe, Germany). George’s research interests focus on coordination polymers, coordination cluster topology and water structures.

In this issue of NJC, George has authored the article Structural variation from 1D chains to 3D networks: A systematic study of coordination number effect on the construction of coordination polymers using the terepthaloylbisglycinate ligand by George E. Kostakis, Luigi Casella, Athanassios K. Boudalis, Enrico Monzani and John C. Plakatouras, New J. Chem., 2011, 35, 1060-1071; DOI: 10.1039/C0NJ01009J. “A systematic investigation of the coordination chemistry of terepthaloylbisglycinate with different metal centres which shows that apart from the coordination number of the metal centre, there are several factors affecting the network dimensionality for the room temperature reactions”, explains George who chooses NJC for the publication of this article due to the journal’s high quality and wide readership.

In his free time, George loves spending time reading, biking, listening to music and cooking.

Hongchen Gu is Professor at the Nano Biomedical Research Center, Med-X Research Institute School of Biomedical Engineering from the Shangai Jiao Tong University (Shangai, China).

His current research interests are the synthesis of nanoparticles for biomedical applications, the magnetic properties studies of nanoparticles and drug and gene delivery nanoparticles-based systems.

In this NJC issue paper, Hongchen and co-workers describes the synthesis of a series of magnetite nanoparticle clusters and single nanoparticles by using polyols with different reductive abilities. “This study indicates that growth kinetics has great impact on the secondary structure of magnetite nanoparticles and determines the morphology evolution of the nanoparticles” says Hongchen.

Facile synthesis and morphology evolution of magnetic iron oxide nanoparticles in different polyol processes by Changming Cheng, Fangjie Xu and Hongchen Gu, New J. Chem., 2011, 35, 1072-1079;  DOI : 10.1039/C0NJ00986E.

NJC was chosen as it is a high impact and fast editing journal in chemistry”

Reading and playing table tennis are Hongchen’s favorite activities.

Closing this month’s authors selection, Neerish Revaprasadu is Professor of Inorganic Chemistry and Chair of Nanotechnology at the University of Zululand (Kwadlangezwa, South Africa).

His current research interest is inorganic materials chemistry and he has authored in this NJC issue the paper Heterocyclic dithiocarbamates: precursors for shape controlled growth of CdS nanoparticles by Linda Dyorisse Nyamen, Viswanadha Srirama Rajasekhar Pullabhotla, Adeola Ayodeji Nejo, Peter Ndifon and Neerish Revaprasadu, New J. Chem., 2011, 35, 1133-1139; DOI: 10.1039/C1NJ20069K.

“The journal has a good readership and is multidisciplinary. The feedback from the editors is always helpful and constructive and also very quick. I have always had a good experience with NJC.”

Out of the lab, Neerish’s favorite activities are reading and travelling.

Hot Article : A 3D metal organic framework exhibiting four different magnetic states.

Sutter and co-workers (Laboratoire de Chimie de Coordination, France) report the synthesis of the 3D metal organic framework of formula [K2(H2O)4Mn5(H2O)8(MeCN){Mo(CN)7}3].2H2O. This new coordination polymer exhibits four different ferromagnetic states showing different magnetic properties depending on the structure and on the presence of H2O molecules and thermal history. Thus, the results described in this paper demonstrate that a porous framework can be achieved with the small cyanide ligand that also ensures good magnetic performances.
