The Inorganic Radiochemistry of Heavy Elements (eBook, PDF)

Methods for Studying Gaseous Compounds

• Format: PDF

Produktbeschreibung

The aim of this book is to facilitate the wider use of advantageous gas phase techniques towards heavy elements. Studies of the transactinoid elements (polyvalent metals) stimulated application of their volatile halides, oxides, and oxyhalides to fast radiochemical separations. Selected results are presented here. Primarily, this book features the physico-chemical basis of experimental methods and techniques. It focuses on evaluation of the desorption energy from data of a single gas-solid chromatography experiment through calculation of desorption entropy. Heterogeneity of the column surface and its chemical modification are taken into account. Several approaches to the estimation of bulk properties of the compounds from experiments with only a few atoms are also discussed. The accuracy of the derived quantities is then analyzed using the Bayesian statistical approach.

The book is aimed at newcomers to the field as well as experts actively engaged in this area of research.

Rezensionen

From the reviews: "This is an interesting and well-prepared book. ... it covers, only the gas-phase chemistry of elements of atomic numbers greater than Z = 103. As a result, it will be of interest to ... readers of JACS. ... In the six brief chapters, the limited data are well evaluated and presented." (Gregory R. Choppin, Journal of the American Chemical Society, Vol. 130 (42), 2008)
