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]”

“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.
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."
"The InChI algorithm turns chemical structures into machine-readable strings of information. InChIs are unique to the compound they describe and can encode absolute stereochemistry. A simple analogy is that InChI is the bar-code for chemistry and chemical structures. The InChI format and algorithm are non-proprietary and the software is open source, with ongoing development done by the community."
"Since its launch in 2005, widespread take-up of InChI standards by public databases and journals has been observed. Today, there are more than 100 million InChIs in scientific literature and products. Numerous databases, journals and chemical structure drawing programs have incorporated the InChI algorithm. These include the NIST WebBook and mass spectral databases, the NIH/NCBI PubChem database, the NIH/NCI database, the EBI chemistry database, ChemSpider and Symyx Draw."
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.
