Sigma-Aldrich is thrilled to announce that its highly acclaimed chemistry review journal, Aldrichimica Acta, has again been ranked #1 by Impact Factor (IF), out of 55 similar journals in the field of Organic Chemistry.  In 2008, the latest year for which such rankings are available, the Acta achieved an impressive Impact Factor of 16.733—a difference of 9.283 points (more than double) between it and the second-ranked publication (with an IF of only 7.450), and a jump of 4.804 points over the Acta's own 2007 IF of 11.929.  In 2008, the Acta also ranked first by 5-Year Impact Factor and by Article Influence™ Score (4.907 compared to 2.712 for the second-ranked journal). The Acta has also been ranked #1 in seven of the past eight years.  These rankings appear annually in the Science Edition of Journal Citation Reports® (JCR), which is published by Thomson Reuters.  JCR, Science Edition, tracks close to 6598 international science journals annually and offers quantifiable statistical data, which allows the systematic and objective ranking of journals by relative importance within their subject categories. 
     The Aldrichimica Acta publishes in-depth reviews on topics of current interest to chemists.  It is published three or four times a year and distributed at no charge to about 120,000 subscribers worldwide who are members of the scientific community.
     Subscription information and all issues dating back to 1968 are available online at http://www.sigma-aldrich.com/acta and on CD-ROM at http://www.sigma-aldrich.com/acta40cd.

Aldrich, a division of Sigma-Aldrich (Nasdaq: SIAL), has released its new "materials by application" Materials Science catalog. The catalog features more than 4,000 products for research in Alternative Energy, Organic Electronics, Metal & Ceramic Science, Nanomaterials, Micro/NanoElectronics and Polymer Science. Each chapter contains technical information and highlights from some of the latest advances in these fields.

"This catalog serves as a materials supply source as well as a tool to assist materials researchers working in the leading areas of modern materials research such as sustainable energy, bio- and soft-materials and electronics and photonics," said Dr. Shashi Jasty, initiative lead for Materials Science at Sigma-Aldrich.

"The structuring of the Aldrich Materials Science catalog is geared toward science and solutions to problems not just traditional materials," said Professor Joachim O. Radler with the Center of NanoScience and Department of Physics at Ludwig-Maximilians University, Munich, Germany. "That's what makes this catalog so valuable."

The printed catalog is a complement to Aldrich's online product catalog, which provides quick access to an easy-to-browse compilation of advanced materials.To request a complimentary copy of the Aldrich Materials Science catalog, please visit http://www.sigma-aldrich.com/mscat or send an email to matsci@sial.com.
