Rare Earth Metal (Sc, Y, Lanthanoids) Bromides and Iodides in Water and Aqueous Systems (Solubility Data Series)

Published Online: 2011-03-01 | DOI: https://doi.org/10.1515/ci.2011.33.2.24

Rare Earth Metal (Sc, Y, Lanthanoids) Bromides and Iodides in Water and Aqueous Systems (Solubility Data Series)

A complete set of compilations will be prepared for the solubilities of all rare earth metal bromides and iodides in water as well as in aqueous solutions containing inorganic and organic substances. The set of compilations related to a selected metal will be introduced with a critical evaluation of all related solubility results, equilibrium solid phases, and a selection of suggested solubility data.

Rare earth metal bromides and iodides are of increasing importance in the production of mercury-free lamp fillings, materials used in spectroscopy, corrosion protection, and catalysis of polymerization and various organic reactions.

This report continues the previous elaborations dealing with rare earth metal halides in nonaqueous1 and aqueous2 solvents:

IYC 2011: Ready, Set, Go!

Personalized or “customized” stamps constitute an alternative form of postage in which a photograph or picture provided by an individual or company is added to the stamp’s design. In the past few years they have become increasingly popular in Europe and North America, particularly for the delivery of personal greetings or the announcement of special occasions (e.g., births, weddings) that could not possibly be featured on “regular” stamps issued by official postal authorities. Since the United States Postal Service will, unfortunately, not be issuing a stamp to honor the International Year of Chemistry (I’ll spare you the details of the story), I decided a few months ago to create and order my own. Illustrated herein is the brainchild of my philatelic stubbornness, a self-adhesive stamp with a rather simple design that features the IYC logo on a white background. My hope is that many readers of Chemistry International will follow through on this idea and create stamps showcasing the chemistry theme of their choice (perhaps a favorite element or molecule?), and thus help promote and commemorate the IYC.

I would also like to mention here three stamp-related events that will take place during 2011. A Global Stamp Competition is the focus of a new IUPAC project intended to draw attention to chemistry as a cultural enterprise. Schoolchildren all over the world are invited to submit entries that recognize the multiple contributions of chemistry to society and highlight its role in the welfare, safety, and health of all people. (Follow this activity on the IYC website @ www.chemistry2011.org/participate/activities/show?id=110) In addition, a “Chemistry on Stamps” Symposium and an associated Stamp Exhibition will take place during the 242nd national meeting of the American Chemical Society in Denver, Colorado, between 28 August and 1 September. Everyone is invited to join in the

celebrations!
