The world's leading resource for coverage of research literature in physics, including astronomy and astrophysics. Its other subject strengths are electrical engineering; control, and computing, including information technology. International journals and conference proceedings are covered, with selected indexing of books and reports. This resource allows searching by specialized fields.
The Web interface for the world's foremost resource for chemical information, Chemical Abstracts. Indexes the literature of pure and applied chemistry and broadly related areas; searchable by text, such as author and research topic; plus chemical identifiers, structures, and reactions. Sources covered include journals, conference proceedings, patents, books, technical reports, and dissertations. Corresponds to the databases CAplus, CAS Registry, and CASREACT, and to the printed resource Chemical Abstracts.
Offers comprehensive, timely collections of critical review articles written by leading scientists. Annual Reviews volumes are published each year for 29 focused disciplines within the Biomedical, Physical, and Social Sciences.
Presents over 500 articles addressing all areas of polymer science including polymers, plastics, fibers, biomaterials, elastomers, and polymerization processes. The resource is updated quarterly with new and substantially revised articles.
The US Patent & Trademark Office (USPTO) site covers patent history, filing, and classification, with a complete database of U.S, patents allowing full text searching of patents granted from 1976 to present; patents granted from 1790-1975 are searchable via classification. Patents can be viewed as images (TIF format). The USPTO site also offers links to some international patent databases. For trademarks, the USPTO site lets you search for active and inactive U.S. trademarks, with words or numerical descriptors, providing online images of the trademarks, dating back to the late 19th century.
The US Patent & Trademark Office also partners with Google to allow powerful full text searching of all U.S. patents, with PDF images and is highly recommended for first-time users of the patent database.
For chemistry, nanoscience, and related fields. Reaxys is based on the combined content of CrossFire Beilstein and Gmelin, and the Patent Chemistry Database (PCD). Reaxys contains experimental reaction and substance data extracted from the major organic, inorganic and organometallic chemistry literature, plus linked literature references. Allows researchers to identify and combine selected reaction steps to generate synthesis strategies. Substance searching includes (sub-)structure, generic and R-group searching, molecular formula, name, etc. Indexes multi-step reactions. Provides indexing and links to U.S. and European chemical and life science patents.
Offers journal articles and book chapters in the disciplines of physical sciences and engineering, life sciences, health sciences, and social sciences and humanities.
Facilitates research-level interdisciplinary search. Use the Basic Search to locate articles in high-impact scholarly journals in science, social science, arts, and humanities. Use the unique Cited Reference search for articles that cite an article you already know of, so you can track citations forward in time.
