This month, our outside cover illustrates an article written by Dr Zdeněk Sofer (Institute of Chemical Technology, Czech Republic) and his colleagues, focusing on graphite oxides.

In their paper, the authors show that more complex products (large amounts of complex ions) than water vapor and carbon mono- and dioxide are produced during the exfoliation process. The team came to the conclusion that the full understanding of the exfoliation mechanism and products is crucial for reproducible scalable synthesis of reduced graphenes on a large scale.

Prof. Kingo Uchida (Ryukoku University, Japan) and his co-workers have designed the inside cover. They focused their research on the development of molecular switches, in particular photoactive systems that are a major challenge in the context of molecular devices and light-responsive systems.

In their paper, they present the synthesis of a diarylethene with an attached malachite green moiety and study the photochromism and halochromism of six states (neutral, mono- and dicationic states under both open- and closed-ring isomeric states) to clarify the effect of combining two dyes. The data obtained will contribute to the design of pH sensitive photoswitches, especially for biological applications and their successful incorporation in various applications and in switchable molecular-based devices.

Also discover a Focus, written by Dr Borkovec (University of Geneva, Switzerland) and his colleagues, dedicated to the intrinsic approach describing microscopic ionization equilibria. The authors present an intrinsic description with examples of increasing complexity, thereby highlighting various strategies to extract the relevant parameters. They also address the notion of group transferability, then the central idea of cluster expansion of the free energy, and finally molecular symmetries and homologous series.

Dear NJC Authors,

Today many editors and reviewers evaluate manuscripts “on-screen” (whether this be a computer, a tablet or even a smartphone). It is quite difficult to read manuscripts in which the tables and figures are collected at the end, because the reader then has to scroll back-and-forth between two or even three different pages while reading the text. To facilitate the work of the reviewers as well as the editors, the New Journal of Chemistry Editorial Board has recently adopted a new requirement for submissions to NJC.

This new requirement is described below, along with some additional important information that we ask you to read.

The editors and reviewers thank you for your attention to this new submission requirement. If you have any questions please contact the Montpellier editorial office and we will be happy to help you.

New Submission Requirement
All submissions to NJC must include a file of the “integrated manuscript”: this is a file with all of the tables and artwork integrated into the text at the point close to where the table/figure/scheme, etc., is first mentioned.
– Tables should be complete with the table number and title above the table and footnotes below. Please place the table in the text at a point where the entire table can fit on a single page (unless the table is longer than a single page).
– Figures/schemes/charts should have the number and caption below the artwork. Avoid splitting the graphic over two pages (when possible) by placing it appropriately in the text.

Please see the figure below showing proper presentation of a table and a figure within the text.

Submissions to NJC that do not include this “integrated manuscript” file will be un-submitted, and the author will be requested to upload the “integrated manuscript” file to complete the submission.

Please note that this new policy does not require authors to use the journal template for NJC article types that do not have a limit on their length (regular Papers and Perspective reviews). However, the latest journal template should be used for Letters and Focus reviews, which are limited to 4 and 6 pages, respectively. Please read more about article types below.

Recommendations
To avoid the shifting of inserted graphics/tables during the generation of the pdf file that is read by the editors and reviewers, we suggest to the author to upload a pdf version of their “integrated manuscript” in addition to the native file. The “file designation” to choose when uploading the “integrated manuscript” file(s) is “article”.

When submitting your manuscript, please be sure to select the appropriate “article type” (see the chart below) from the list given during the online manuscript submission process. (A fifth format is also published—Comments—which are meant for scientific comments on a paper previously published in NJC.)

The October outside cover, designed by Marcus Herlitschke (Jülich Centre for Neutron Science, Germany) et al., presents their paper in which the first experimental results concerning unusual magnetic properties of FeNCN are reported.

This study reveals the unconventional behaviour of the magnetic parameters below the Néel temperature of 350 K. The comparison of the obtained data with literature data of iron monoxide reveals very similar iron phonon modes with a small softening and a slightly reduced sound velocity. The authors showed that iron monoxide and iron carbodiimide exhibit a similar local iron environment with a mean nearest neighbour distance of about 2.2 Å in an octahedral coordination by oxygen or nitrogen, respectively.

The authors also presented measurements of FeNCN, featuring similarities and differences to the related iron monoxide. In summary, the iron carbodiimide is a particularly attractive target for magnetic investigations using Mössbauer spectroscopy and magnetometry.

The inside cover illustrates a paper written by Karl Wallace (University of Southern Mississippi, USA) and his colleagues who are interested in the design of new molecular probes.

The authors have synthesized two coumarin-enamine chemodosimeters which can selectively detect the cyanide ion and investigated the spectroscopic properties in various organic solvents.

This month’s outside cover illustrates an article by Prof. Richard Keene (James Cook University, Australia) and co-workers in which they report important observations in the development of multinuclear ruthenium complexes as a new class of anticancer agents.

There has been little success in developing drugs that are active in cancer cell lines resistant to cisplatin. Consequently, there was a need in developing “non-classical” platinum complexes – complexes that can bind DNA differently than cisplatin and its analogues. Thus, multinuclear platinum complexes, where two or more platinum coordination units are linked by a variety of organic ligand bridges, represent a genuinely new class of anticancer drug.

This study shows that it should be possible to optimize cellular uptake and the kinetics of DNA binding, and thereby produce dinuclear ruthenium(II) complexes with significant clinical potential.
