An academic price is awarded to degree-granting (Assoc., B.S., M.S., Ph.D.) institutions and organizations that provide resources for student’s course work that are affiliated with the degree-granting institution. Institutions may be required to submit documentation to verify eligibility.
Data on the Go
PDF-4+/Web 2020, formally known as WebPDF-4+, provides portability to the PDF-4+ database via the internet. It enables access to the entire suite of programs and data files, so that it is equivalent to PDF-4+ 2020. PDF-4+/Web 2020 contains 426,000+ entries. It combines the world’s largest sources of inorganic diffraction data from crystals and powders into a single database. The result is a comprehensive collection of inorganic materials, produced in a standardized format that can be rapidly searched for unknown phase identification. Extensive data mining is facilitated with 128 display fields coupled with 75 searches.
PDF-4+/Web is designed to support automated quantitative analyses by providing key reference data required for these analyses. It also contains an array of tools that supplement conventional analyses, such as a full suite of data simulation programs enabling the analysis of neutron, electron, and synchrotron data, in addition to conventional X-ray data.
PDF-4+/Web features digitized patterns, molecular graphics, and atomic coordinates. These features incorporated into PDF-4+ enhance the ability to do quantitative analysis using third party software by any of three methods: Rietveld Analysis, Reference Intensity Ratio (RIR) Method, or Total Pattern Analysis.
