The turn of the year is a good time to reflect on the privileges one has enjoyed in the preceding twelve months, and to remind oneself not to take everything for granted. We are deeply grateful to all the authors who have chosen to offer us their hard-earned results for publication and have entrusted us with making the ensuing editorial decisions. With many excellent papers, it was sometimes difficult to choose from the nearly 5000 submissions that have come in in 2011, but we do believe that the ˜750 publications selected are more than worthy of the community's attention. The editorial team were all delighted in June when the Advanced journals family posted spectacular double digit percentage improvements to their impact factors, testimony to both the relevance and discoverability of papers published in our journals. Advanced Materials leapt to 10.880 (+30%), Advanced Functional Materials to 8.508 (+22%), and Small to 7.336 (+19%). Impact Factors are averages and should be treated as such, hence we are keen to highlight the ten biggest contributors in terms of citations. Table1 lists the top ten most cited articles published in 2008–2009, i.e., the papers on which the 2010 IF calculation is based. The immediate influence of Advanced Materials papers on the community is also evident as shown in Table2, which lists the most-cited 2011 paper in each article category. Our congratulations go to the authors!

A peer-reviewed journal cannot function without the scientific community's goodwill. For the many reports written in 2011, we would particularly like to thank John Rogers, (Urbana), Frederik Krebs (Roskilde), Yongshen Chen (Tianjin), Sir Richard Friend (Cambridge), René Janssen (Eindhoven), Howard Katz (Baltimore), Yunqi Liu (Beijing), Michael McGehee (Stanford), Dieter Neher (Potsdam), and Gaoquan Shi (Beijing). Naturally, we are also much indebted to the writers of the other approximately 3500 reports. Our heartfelt appreciation goes out to the community for this spectacular show of commitment to peer review and support for Advanced Materials. Last but not least, our Editorial Advisory Board has again been instrumental in anchoring us to the community and contributing expertise in many ways including reviewing, encouraging scientists to publish with us, advising us on hot topics and rising stars, and generally supporting our journals with ideas and action.
In 2011, institutions from around the globe again contributed Special Issues to Advanced Materials, see Figure1. The National Institute of Standards and Technology (USA) opened with Issue 3, “Materials Science at NIST”, Tsinghua University (China) celebrated its centennial anniversary in Issue 9, and researchers at the University of California Santa Barbara did a tour de force of their materials and nanoscience activities with Issue 20. I assume they also generated the most envy with their front cover, an aerial photograph of the UCSB campus bordering on beaches and the Pacific. The University of Erlangen–Nuremberg in Germany tackled the themed double Issue 22–23 on “Hierarchical Structures Towards Functionality”, and several institutes in Madrid joined forces to present a broad range of materials research from the Spanish capital in Issue 44.
