Physical and Theoretical Chemistry
(QD:450-731)
QD 450 Periodicals, Societies, Congresses, Serial Collections, Yearbooks
Summary:
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.

QD 466 Chemical Elements. Nature and Properties. General Works
Summary:
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
Summary:
"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.
To Search:
Select an element from the Periodic Table; physical and chemical data and
properties for the selected element will be displayed..
