Newly-released ISI® citation data shows the impact factors of RSC Journals, rise by an average of 10%.  

Among the headline success stories is Chem Soc Rev, the RSC's general chemistry review journal; it sees its impact factor rise by 27% to 13.7 and places it amongst the most highly cited review journals.  Meanwhile CrystEngComm  becomes the leading European journal in crystal engineering, with an impact factor of 3.5.  Dalton Transactions and Journal of Materials Chemistry, the first weekly journals in their fields, also strengthen their positions; Dalton Transactions remains the leading European general inorganic chemistry journal, while Journal of Materials Chemistry's impact factor rises by a staggering 36%.  

Organic & Biomolecular Chemistry also moves forward; now with an impact factor of 2.5, it can be considered one of the leading European journals in the field.  And finally, pioneer in its area of research, Lab on a Chip, consolidates its position with a healthy rise to an impact factor of 5.3, the second highest impact journal in the area of nanoscience and nanotechnology.  

Impact factors provide an indication of the average number of citations per paper.  Produced annually by ISI®, they are calculated by dividing the number of citations in a year, by the number of citeable articles published in the preceding two years.

Topical research ...

But it is not just our impact factors that are impressing RSC authors and readers; work published in RSC journals is also amongst the most topical . and that's official!  The immediacy index for PCCP (Physical Chemistry Chemical Physics) for example, is the highest for any journal publishing primary research in the fields of physical chemistry or chemical physics, for the second consecutive year.  This is complemented by a 20% rise in its impact factor.  Meanwhile, ChemComm, sees it's immediacy index rise to 1.02. 

The immediacy index is a measure of how topical and urgent the papers published by a journal are. It is calculated by dividing the number of citations to articles published in a given year by the number of articles published in that year.  It can therefore be useful for measuring the success of a new journal; impact factors can only be calculated from the third year of a journals publication. The RSC's new interdisciplinary journals, Soft Matter and Molecular BioSystems, duly provide further cause for celebration with extremely encouraging figures of 1.0 and 0.7 respectively.

These impressive new figures, coupled with the RSC's position as the fastest publisher of chemical science research, reinforce the society's reputation as the home of exciting new research.
