New Non-Java CAS Structure Editor Available in SciFinder

No Comments »

CAS announces that SciFinder now features a new version of the CAS Structure Editor that does not require the use of a Java plugin. The Java version of the editor is still available, but users can now easily select their preferred editor.

The non-Java editor is an easy-to-use option. However, there is some missing functionality in the new editor. Due to the pressing need of some users still experiencing Java-related issues, CAS felt it important to release the editor as soon as a viable working version was available.

The Non-Java structure editor allows SciFinder users experiencing problems with Java to draw structures for substance and reaction searches. The available features are equivalent to those in the Java version, and some additional convenience features will be released shortly.

Users experiencing problems with the Java-based structure editor also have the option to download a standalone structure editor that can be used in conjunction with SciFinder.

Note: With minor exceptions, the standalone version has the same features as the Java-based version.

Additionally, the latest SciFinder release features the following updates:

  •  Analyze reaction answer sets by reagent to more quickly identify your synthesis of interest.
  •  View substance and supplier information simultaneously now that the Quick View feature is available from Commercial Sources answer sets. In addition, many top catalog entries now feature direct links to supplier emails from right within SciFinder.
  •  Update user account information more easily with a new account management link to myCAS® available in Preferences.
  • SciPlannerTM how-to guides are now more easily accessible to help you make use of the full power of the features and functionality available within SciPlanner.

SciFinder Introducing New Release this Summer

No Comments »

The American Chemical Society is introducing a new version of its SciFinder Scholar database this summer. Two video previews are available for previewing the new features:

-       Introductory video highlighting SciFinder design and key content capabilities.

-       Help file tutorial that offers a quick tour of the new design.

Also available is an introductory tutorial in PDF format – http://library.uml.edu/docs/introducing-new-scifinder.pdf

SciFinder Scholar is a comprehensive search and discover platform that offers options for exploring substances, reactions, and patent and journal references:

Substances — includes chemical structures, chemical names, CAS Registry Numbers, properties, commercial availability and regulatory information.

Reactions — an extensive database of current chemical reaction information including reaction schemes, experimental procedures, conditions, yields, solvents, catalysts, as well as commercial availability of substances with direct links to leading producer and supplier sites.

References — current chemistry and related science information from journals, patents, dissertations, and more.

 Access to SciFinder requires registration.

 

SciFinder Scholar allows unlimited usage

No Comments »

The UML subscription to Scifinder Scholar from Chemical Abstracts Service (CAS) is now available for unlimited simultaneous user logins for all UML students, faculty, and staff.

Prior to this upgrade to CAS’s new Academic Unlimited Access Program, simultaneous usage was restricted to five users at any one time. Now any number of users can access the resource simultaneous 24/7.

Scifinder Scholar (SFS) provides citations, abstracts, and detailed chemical indexing for over 12,000 journals in chemistry and related fields.  Material covered reaches back into the late 1800’s.  SFS also provides the complete Medline database, with similar indexing.  SFS offers a current alerting service, and its Chemport service will connect you to the full text articles, if UML has a subscription to the title.

All new users of Scifinder Scholar must register for their own individual accounts, using their uml email address.  CAS will send a confirming email which must be answered before your account is activated. For further instructional information about registering, please visit this SciFinder Scholar Research Guide.

Access to SciFinder Scholar is available from the Library’s home web page alphabet index list as well as from most science-related database subject pages.

For any questions about SFS use, email or call (x 3209) Marion Muskiewicz, Science Librarian.

Reaxys chemical database trial

No Comments »

Elsevier is providing UMass Lowell with a one month free trial to their Reaxys database. The trial is available from April 14 to May 14, 2011.

Reaxys is a unique web-based chemistry workflow solution which integrates searches for reaction and substance data with synthesis planning and chemical sourcing. It contains historical data dating back to 1771 and coverage of important current journal and patents within chemistry. The data excerpted from the journals and patents meets carefully controlled selection criteria – namely that all organic, inorganic and organometallic properties and data are excerpted only if they have a structure, experimental fact and a credible citation.

The reaction and substance data within Reaxys is experimentally validated – not calculated – so that less time is spent interrogating results. Its synthesis planner supports the evaluation of alternative synthetic routes and allows chemists to identify and combine selected reaction steps. Sophisticated relevance ranking algorithms combine with filtering tools help prevent chemists from reading irrelevant articles and pursuing unsubstantiated references.

Enhanced interoperability between Reaxys and ScienceDirect further improves the discoverability and visualization of chemical structures. To further improve discoverability and usefulness of the chemistry, authors submitting articles to selected journals are invited to contribute structure (MOL) files of their key compounds. These structure files will be used to visually display all the key compounds referenced in the article in a single scrollable list and will contain direct links to Reaxys, straight from ScienceDirect. It is already possible to access the full-text literature from Reaxys; now Reaxys content is available from ScienceDirect, completing the circle. Furthermore compound identifiers (InChI keys) will be added to the structures, making both the article and its key compounds more discoverable through mainstream search engines like Google.

More information is available here:

Access to this trial is available through the library’s New Database Trials and Subscriptions webpage.

Please post comments concerning any aspect of this trial; it aids significantly in our decision-making process.
