Dalton Transactions: still growing for the community

In 2012, Dalton Transactions published in excess of 1500 articles, marking an 8^th consecutive year of growth where we have more than tripled our content (Fig. 1). And we haven't just been growing the size of the journal – the impact factor has risen 28% since 2005 to the current value of 3.84.

The continued success of the journal is thanks to the support from the scientific community. We would like to thank our authors, readers, Board Members, referees and Associate Editors who work to ensure our content is of the highest standard and published in a timely manner. In particular, we would like to thank Professor Shinobu Itoh who is retiring from his position as Regional Associate Editor for Japan. Professor Itoh joined the Editorial Board in 2007 and has helped develop the journal in this region over the last 5 years.

We would also like to welcome our new Associate Editor, Professor Masahiro Yamashita, who is based at Tohoku University. If you would like to submit your article to Professor Masahiro Yamashita or any of our other Associate Editors, you can choose your preferred Editorial Office upon submission. Full details of the journal's Associate Editors and their Editorial Offices are given in Table 1.

Dalton Transactions continues to publish research from all areas of inorganic, organometallic and bioinorganic chemistry. While the key subjects remain at the core of the journal, we also publish Themed Issues, bringing together the best articles in topical research areas or highlighting emerging subjects. Table 2 gives full details of the Themed Issues published in 2012. There are several Themed Issues planned for 2013, including: Boranes and Borohydrides (Guest Editor: Simon Aldridge), Bioinorganic Chemistry (Guest Editor: Emma Raven), Mechanistic Organometallic Chemistry (Guest Editor: Robert Crabtree), a tribute to David Cole-Hamilton (Guest Editors: Duncan Bruce and Derek Woollins), Chemistry and Applications of Metal Complexes (Guest Editor: Maria Amélia Santos), N-Heterocyclic Carbenes (Guest Editor: Catherine Cazin), Advances in Metal-Catalysed Polymerisation (Guest Editor: Philip Mountford), Vanadium in Bioinorganic Chemistry (Guest Editors: Debbie Crans and Craig McLauchlan) and Molecular Precursors for Precision Synthesis of Nanomaterials (Guest Editors: Christophe Copéret and Maksym Kovalenko).

Our Dalton Discussion Themed Issues prove very popular and last year’s Dalton Discussion 13 issue, ‘Inorganic Photophysics and Photochemistry – Fundamentals and Applications’, was no different. We would like to thank Dalton Division Council and the organising committee, especially the Chair, Professor Mike Ward, for their hard work in organising the meeting. The Dalton Discussion format differs slightly from other conferences in that speakers are allotted short 5–10 minute slots to deliver a brief overview of their latest research based on the contents of their article. This is followed by an in-depth discussion amongst delegates to explore the full details of the research. Articles presented at Dalton Discussion meetings are subsequently published in a Themed Issue of Dalton Transactions. We are looking forward to this year's meeting, Dalton Discussion 14: Advancing the Chemistry of the Actinides which will no doubt continue to build on the successful conference series.

Featuring two one day meetings, the 4^th Dalton Transactions International Symposium was held in November 2012, where leading speakers from the host universities and from around the world delivered a selection of lectures covering organometallic chemistry and catalysis. More details can be found on the symposium website, www.rsc.org/DTIS4 and our blog, http://blogs.rsc.org/dt/. Remember, you can keep up to date with all the latest developments in inorganic chemistry and the journal by also following us on twitter @DaltonTrans.

You may have seen some of our Board Members, Associate Editors or Editorial Staff at several other conferences throughout the year. These include China UK Symposium on Metal–Organic Frameworks – Properties and Applications, China; Spring ACS Meeting, USA; 95^th Canadian Chemistry Conference and Exhibition, Canada; Gordon Research Conference – Inorganic Chemistry, USA; XXV International Conference on Organometallic Chemistry, Portugal and the International Conference on Coordination Chemistry, Spain. We also sponsored over 30 poster prizes at conferences from countries around the world, including Germany, UK, Greece, Italy, Spain, Canada, Brazil, Japan, China and South Korea. Thank you to those who helped us arrange these awards and congratulations to the winners. If you are organising a conference this year and you would like us to sponsor a poster prize, please let us know at dalton-rsc@rsc.org. Our international reach is also reflected in our content. Last year, Dalton Transactions published research from authors spanning almost 70 countries, building on the accolade as the leading European journal for inorganic, organometallic and bioinorganic chemistry.

Thank you to all those who support Dalton Transactions. We hope that you are as excited as we are to see what new discoveries await us in 2013.
