|Knovel expands Crude Oil Assay Database and boosts Chemical Data Records|
Two of Knovel’s Critical Content Databases have received significant updates. Yaws’ Critical Property Database for Chemical Engineers and Chemists has increased by 160,000 data records to include almost 450,000 records in total. With this update, Knovel offers the largest compilation of correlations for chemical engineers online. In addition, the Crude Oil Assay Database has expanded to feature over 400 assays.
Princeton has a subscription to Knovel. The Knovel database is constituted mainly of engineering resources…some manipulable.
International Year of Crystallography (IYCr 2014)

The International Year of Crystallography 2014 (IYCr 2014) highlights the continuing importance of crystallography.
It celebrates the centennial of X-ray diffraction. William Henry and William Lawrence Bragg showed that diffracted X-rays can be used to map the positions of atoms within a crystal. This allowed the detailed study of crystalline material.
Additionally, it commemorates the 400th anniversary of Kepler’s first studies which lead in 1611 to the observation of the symmetrical form of ice crystals. This was the beginning of the wider study of the role of symmetry in matter.

“The Environmental Protection Agency (EPA) publishes the “Science Matters” newsletter to inform the general public about its research and advocacy activities on behalf of the American public. The newsletter was first published in 2010, and is a terrific source of information on everything from green chemistry to renewable energy. In the About this Issue area, visitors can learn about the topical focus of each issue. In the Science Features, visitors can read articles such as “Nanomaterials: Harnessing the Potential, Understanding the Risks” and “Partnerships for a Safer Chemical Future.” Users shouldn’t miss the Ask a Scientist feature, which profiles a different EPA scientist in each issue. The In the News area brings together updates about new partnerships with colleges, universities, and international collaborators. [KMG]”

Free access is offered through 31 December, 2013. One must register though:
“Targets” reviews, communications and regular papers. Intersects the fields of materials and molecular science. Wants high-impact works in: materials design, synthesis, growth, analysis, characterization, properties and functions, fabrication and device manufacturing, and system integration and applications of materials.
Besides NTIS, available via Engineering Village/Elsevier, Princeton University now has access to NTRL (National Technical Reports Library) (1800+) from the U.S. Government.
It provides indexing and access to a collection of more than 2,000,000 historical and current unclassified government technical reports archived by the National Technical Information Service. Over 500,000 documents are available in full-text from departments such as Department of Energy, NASA, and the Environmental Protection Agency.
NTRS differs from NTIS in that it covers more years, mainly from 1960, but as far back as 1800. The database is updated daily and there is full text for about 25% of the reports.

"Chemical Abstracts Service (CAS), a division of the American Chemical Society, has announced that it is on track to register the 50 millionth unique chemical substance on September 7. The CAS REGISTRY claims to be the most comprehensive and high-quality compendium of publicly disclosed chemical information. This milestone comes only 9 months after CAS registered its 40 millionth substance.
REGISTRY is the only integrated comprehensive source of chemical information from a full range of patent and journal literature that is curated and quality controlled by scientists working around the world. For more than 100 years, CAS scientists and colleagues in several nations have meticulously analysed and indexed publicly disclosed global scientific information to build up the unique REGISTRY resource that provides not only chemical names, the unique CAS Registry Number, and vital literature references but also ancillary information such as experimental and predicted property data (boiling and melting points, etc.), commercial availability, preparation details, spectra, and regulatory information from international sources.
CAS scientists follow rigorous criteria that maintain high quality and reliability of information in its REGISTRY. Scientists identify reputable sources and use consistent analysis before registering a substance. REGISTRY is available to scientists through CAS’ product, SciFinder, and its STN family of products. With these advanced search and analysis technologies, CAS helps scientists find reliable information that is vital to their research process."

InChIs, are machine-readable, alpha-numeric character strings first developed byNow the InChI Trust is carrying on the work to develop and expand the algorithms for open source accessibility of even more chemical structures.
From Today’s Knowledgespeak Newsletter:
Nature Chemistry — the second issue is now online, and covers a wide range of topics, including catalysis, mesoporous materials, synthetic methodology, anion transport, and DNA conductivity. In addition, there is a commentary about pre-university chemical education, a review article on Mobius aromaticity and a thesis article that looks at alternative forms of the periodic table.
