Makes it easier for American citizens to find and access information from across the DOE complex nationwide, without knowing DOE's organizational structure. Information is offered in the DOE's four broad mission areas: science and R&D results; energy and technology for industry and homeowners; energy market information and analysis; and nuclear security and environmental management.
"Retrieves relevance-ranked individual site results from 17 distributed DOE databases and 82 websites, or 20 million searchable pages, with hyperlinks to the databases/pages where the original content can be viewed." --OSTI press release dated February 15, 2013.

v. : ill. ; 30 cm.
Provides graphical abstracts of new developments in natural product chemistry, selected from dozens of key primary journals. Coverage includes: isolation studies, biosynthesis, new natural products, known compounds from new sources, structure determinations, and new properties and biological activities. Over 200 graphical abstracts are contained in each monthly bulletin, including structure diagrams, trivial and taxonomic names, molecular formulae, physical and biological properties. Subscribers to the monthly print bulletin also have free access to Natural Product Updates Online, the fully searchable web database which allows users to search across all items published in NPU to date. This service provides full text search capability on a variety of terms. An email alerting service is also available, allowing users to sign up for an email message every time a new monthly bulletin is published online.

The Atomic Spectra Database (ASD) contains data for radiative transitions and energy levels in atoms and atomic ions. Data are included for observed transitions of 99 elements and energy levels of 52 elements. ASD contains data on about 900 spectra from about 1 Å (Ångströms) to 200 micrometers, with about 70,000 energy levels and 91,000 lines, 40,000 of which have transition probabilities listed. The most current NIST-evaluated data associated with each transition are integrated under a single listing.

NIST X-ray Photoelectron Spectroscopy (XPS) Database gives easy access to the energies of many photoelectron and Auger-electron spectral lines. Resulting from a critical evaluation of the published literature, the database contains over 22,000 line positions, chemical shifts, doublet splittings, and energy separations of photoelectron and Auger-electron lines. A highly interactive program allows the user to search by element, line type, line energy, and many other variables. Users can easily identify unknown measured lines by matching to previous measurements. Version 4.1 which contains an additional 4368 data records for a total of over 33,000 data records. Version 4.1 also contains new reference photoelectron binding energies, reference Auger-electron kinetic energies, and reference Auger parameters for many elemental solids from recent analyses of Handbook data. Wagner plots are now available for 61 elements.
