A kinetic model described in the latest issue of Progress in Reaction Kinetics and Mechanism expresses the oxidation of maleic acid in solution using a novel modified PAN catalyst/hydrogen peroxide system. This model provides a superior fit to the experimental data compared to kinetic constants from the literature.

With continuing population growth and rapid economic development of China, the environmental quality of rural soil is becoming more and more important with regard to human health. A study reported in Chemical Speciation and Bioavailability assesses the spatial changes of Cd and Zn in the surface soil in the Henan Province cultivated area.

The preparation and reactions of B-norsteroidal 6-ketones and their relatives are reviewed in the context of the stability of the A/B and B/C ring junctions and the stereochemistry of the addition reactions to the carbonyl group. This review is a sequel to a previous article on the reactions of B-norsteroidal 4- and 5-enes (C. Uyanik and J.R. Hanson, J. Chem. Res, 2009, 713.)

As well as exhibiting catalytic activity for many chemical reactions, ionic liquids are used as replacements for conventional toxic solvents. They can be used to prevent chemical pollution. In Science Progress 94(3), Professor Harry Jenkins highlights the main characteristics of ionic liquids, presenting them in a form readily assimilated by newcomers to this area of research. An extensive glossary is featured as well as a chronological list which charts the major areas of development.

Time-dependent intergranular crack-growth in Ni-base superalloys is well known, however, there is a lack of understanding of the detailed effects of oxygen interaction in the crack tips.  The methodology of accessing and analysing this region is described in Materials at High Temperatures 28(4) which highlights some of the issues arising from  Microscopy of Oxidation 8.
