NJC April 2015 OFC - Dr KanamoriDr Kanamori (Kyoto University, Japan) and his colleagues’ work illustrates the outside cover this month.

Hierarchically porous monolithic materials are used as adsorbent, separation media and catalyst (support) due to their excellent accessibility to the pore surface and high permeability as well as easy recyclability and reusability. In this article, the authors report the synthesis of hierarchically porous zirconium phosphate (ZrP) monoliths with size-tunable co-continuous macropores from ionic precursors via a sol–gel process accompanied by phase separation followed by supercritical drying. They demonstrate the applicability of this new monolithic porous material as a green platform for the removal of toxic metal ions in aqueous solutions under continuous flow conditions, which shows promising results as a water purification device.

March 2015 OFC Liu Nan-NanThis month’s outside cover illustrates the work of Nan-nan Liu (Harbin University of Commerce, China) and her colleague Yi-hong Ding, in which they theoretically predict a new type of metal-metal bond passing through the ligand in inverse sandwich compounds. The molecules are roughly estimated as potentially electro-conductive by the low HOMO–LUMO gaps. According to the authors, their work could raise interest in the structural properties of inverse sandwich compounds.

NJC issue 02 out now

NJC OFC Feb 2015 - Dr AakeroyDr Christer Aakeröy (Kansas State University, USA) designed the outside cover this month. In their article, Dr Aakeroy and his colleagues describe how a simple electrostatic view of hydrogen bonds can lead to predictable and highly site-specific molecular recognition events.

The deceptively simple act of molecular recognition is achieved by balancing a range of non-covalent forces, and the synthesis of more complex architectures requires a systematic and targeted application of hierarchical self-assembly. By addressing specific questions about how small molecules prefer to bind to each other, it may be possible to devise reproducible and reliable links between molecular structure and practical methodologies for directed non-covalent synthesis.

Molecular electrostatic potential dependent selectivity of hydrogen bonding, Christer B. Aakeröy, Tharanga K. Wijethunga and John Desper, New J. Chem., 2015, 39, 822-828. DOI: 10.1039/C4NJ01324GNJC IFC Feb 2015 - Dr Gauthier

The inside cover is proposed by Dr Gilles Gauthier (Universidad Industrial de Santander, Colombia) and co-workers to illustrate their study on the influence of the Mn precursor on the formation of polytypes.

The authors studied in detail the phenomenon and also prepared a new polytype using a specific chemical route. The results show that even small changes in the mean oxidation state of the transition metals can guide a synthesis route in different ways and lead to different polytypes.

Their work contributes to the understanding of the solid state reactivity, giving new insights in the synthesis of new compounds,  destined for magnetic materials and other applications.

Capture of carbon dioxide by conjugated microporous polymers

Towards the global efforts to reduce carbon emission, carbon dioxide capture is currently being investigated as a potential strategy towards this goal.

Conjugated microporous polymers (CMPs) as a sub-family of microporous organic polymers (MOPs) are good candidates for CO2 capture because of the wide-ranging flexibility in the choice and design of components and the available control of pore parameters.

Dr Renqiang Yang and his colleagues (researchers at Chinese Academy of Science, University of Chinese Academy of Science and Taiwan National Central University) designed and synthesized three phospine oxide-based microporous polymers TEPO 1-3 owning strong affinity for CO2. The effects of the rigid length and fuctionalization of the monomer skeleton on the performance of porous materials has been investigated. Although the BET (Brunauer-Emmett-Teller) surface area of the TEPOs are less than 600 m2 g-1, the three polymers exhibit relatively high sorption abilities for CO2 (8.40 wt%) and ultrahigh hydrogen uptake (1.02 wt% at 77K/1.0 bar) compared to materials with similar BET surface areas. Interestingly, the polymers obtained exhibit remarkable performance in separating CO2 over CH4 as the selectivity of CO2/CH4 is a high as 15.5 at 273K.

This work reveals clearly that the gas uptake capacity of materials is highly depending on the length of rigid skeleton and the modification of functional groups in the monomer structure.

NJC: important information for our authors about new submission requirements

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.

Integrated Manuscript - NJC

Figure showing pages of an "integrated manuscript" with table and figure incorporated in the text

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.)

NJC issue 10 out now

NJC Oct outside cover 2014 - HerlitschkeThe 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.
