Buzzing with Activity

It is difficult to believe that already a year has passed since the launch of Advanced Energy Materials; time flies when exciting things are happening. When we set out to launch AEnM, we were intentionally conservative in our expectations regarding the volume of the journal in order to ensure that quality be the maxim rather than quantity. In practice, the uptake of AEnM by the community proceeded at amazing speed. By the end of 2011, more than 750 manuscripts will have been submitted, perhaps even 800. From January to November, the acceptance rate has developed from approximately 35 to 25%, underscoring both the journal's popularity and stringent quality standards.

As a result, 162 manuscripts have made it into the journal, some 60 more than originally anticipated. If anyone ever had doubts about Advanced Energy Materials attaining critical mass, they are now safely buried under 1236 pages. As there clearly is ample substance, we will accelerate to monthly issues in 2012 to provide faster final citations and page numbers to our authors. Watch out for the newest issue each third week of the month, both in print as well as online at


In my opinion, Impact Factors should always be taken with a grain of salt – I recommend sapiensium alertide. IFs have become a potent scientific currency that frequently plays a role in success, career advancement, and research funding, to name just a few effects they have. While we are very happy that our Advanced journal family did exceptionally well in the 2011 ISI Journal Citation Report, I feel the urge to point out that these are statistics, and do not per se provide safe judgement from afar on the individual article. It is impossible to reduce scientific relevance to one single unconditional number. While Impact Factors serve well for orientation and as eye-catchers, I think it is essential to consult the individual articles of a journal in order to judge their true merit. Highly-cited papers are frequently brilliant, memorable, controversial, or milestones. The citation count, however, doesn't guarantee that they aren't overvalued, obsolete, excessively self-cited, wrong, faked, or serving as a bad example to an entire community – or any combination there of. I therefore invite all readers to have a look at those five articles in Advanced Energy Materials which received most citations to date and form their own opinion (see Table1).

We are grateful to all authors who in the last year have made this journal a spectacular success and a riveting read. It has been a privilege and pleasure to edit this journal, and we would like to express our appreciation for the community's acceptance of Advanced Energy Materials.

While the authorship is evident from the publications, I feel that after a year, words of thanks are in order regarding the invaluable contribution made to the journal by our reviewers. I therefore direct your attention to Table2, which lists all reviewers that have thrice or more within the last twelve months reviewed for Advanced Energy Materials. We are particularly indebted to those at the top of this list who have contributed up to seven reviews and have therefore been instrumental in providing swift decisions. Naturally, I am also very grateful to the many other reviewers who have substantially helped sustain the quality of the journal and demonstrated that this is an active and eager community which embraces both the competitive and collaborative aspects of peer review.

My gratitude also goes out to the Editorial Advisory Board, which has been instrumental in building the journal's reputation as well as having contributed much advice and support. It has grown from an original nine members for the 2010 Special Section in Advanced Materials to now 25 as I would like to welcome our four new members Anne C. Dillon (National Renewable Energy Laboratory), Frederik C. Krebs (Technical University of Denmark), Debra Rolison (Naval Research Laboratory) and Gregory Scholes (University of Toronto). we are very happy to be able to further add to the already considerable expertise assembled there.

With regard to topic spread, the trend already observed in July remains valid. Figure1 shows the distribution for 2011, which reflects the strong interest in all kinds of solar cells and electricity storage. We are particularly hoping that the pie chart motivates more authors to submit papers on thermoelectrics, magnetocalorics, hydrogen generation and storage, fuel cells, and efficient lighting, which are very welcome to the journal.

Last but not least I would like to reiterate the free availability of Advanced Energy Materials through 2012. Prospective users lacking access at their institution should contact their librarian to register at for complimentary online access for the next twelve months.

In conclusion, not only have you, the scientific community, made this journal possible, but Advanced Energy Materials is positively buzzing with activity. We look forward to the next fascinating year of energy-related research and your next paper!
