Journal of Chemical Physics

Journal of Chemical Physics, a publication of the American Institute of Physics is detailed in this site, sponsored by the American Institute of Physics (AIP), an organization begun "...for the purpose of promoting the advancement and diffusion of the knowledge of physics and its application to human welfare." The journal is the "...bridge...between journals of physics and journals of chemistry." The site is a compilation of available issues of the publication, which are listed chronologically, beginning with the most recent issue. No actual texts are open for viewing within the site; users should seek ordering and subscription information through the applicable link at the top of the site's main page.
Each issue listing features the volume and issue numbers, along with the journal's individual release date. Users should select an issue of interest; a listing of articles is then displayed, showing the texts, in their order of appearance within the periodical. Each article's record includes: (1) the title; (2) name(s) of author (initials, last name); (3) the page numbers where the article is located within the issue; and (4) a designation (via an icon) noting whether the text is available for ordering. Users should scroll to view site listings and issue listings.
At the bottom of the site's main page are three major links. The first gives access to the AIP homepage, for further information. The second opens the "Titles in Physics" homepage, a service which allows users to search 47 AIP society journals for topics of interest. The last link, "Journal List," accesses a comprehensive listing of all AIP journals. The site is maintained by the American Institute of Physics; New York.

X-Ray Properties of the Elements

X-Ray Properties of Elements is a division of the site, X-Ray Interactions with Matter, sponsored by the Center for X-Ray Optics (CXRO) at the Lawrence Berkeley National Laboratory (LBNL). The center "...has complimentary roles: demonstrating the scientific capabilities and usefulness of the x-ray and extreme ultraviolet regions of the spectrum and developing equipment and techniques which make those capabilities widely and readily available."
At the top of the site's main page is a search area with two fields: (1) element symbol (abbreviation); and (2) energy (eV) level. Below this area is an extended explanantion of results from searches, all information featuring documentation. Users should scroll to view this portion of the main page. After filling in search fields, a results page will be displayed featuring: (1) search criteria; (2) information on atomic properties (atomic weight, photoabsorption cross section, f1, and f2); (3) information on material properties (density, delta, beta, attenuation length, and critical angle); and (4) electron binding energies (eV) (various featured).
At the bottom of the site's main page is a link to the site's server and to e-mail the site's creator. The site is maintained by Eric Gullikson; Center for X-Ray Optics, Lawrence Berkeley National Laboratory; Berkeley, California.

QD 467 Classification. Periodic Law


"WebElements is a WWW Periodic Table database and utility packages constructed with data abstracted from the HyperCard program MacElements. [It] contains links to data for the first 105 elements."
"WebElements is located at a number of sites around the world. In order to minimise network traffic, particularly over busy international links, please use a site close to you. Select from the following sites:

"The home of WebElements is at the University of Sheffield in South Yorkshire, England...[T]he WebElements home site was first constructed and is maintained by Mark Winter."
WebElements also contains links to an isotope pattern calculator and an element percentage calculator.
