Platinum Metals Review - Volume 17, Issue 1, 1973

A wide variety of platinum(II) complexes have been synthesised and tested for anti-tumour activity resulting in the identification of additional potentially active anti-tumour drugs. Several structural features have been shown to be necessary for a complex to show activity. This article follows up the article by Professor Barnett Rosenberg in the April 1971 issue.

New and improved compositions of pastes for ruthenium resistors have been developed at the Johnson Matthey Research Laboratories. Evaluation of the properties of such resistors shows that these materials are suitable both technically and economically for use in circuits designed for the domestic electronics market. This article is based on a paper given at Internepcon 72, Brighton, last October.

The ordering of the interesting family of alloys based on the platinum group metals has been hitherto somewhat neglected, partly due to problems of specimen preparation. Techniques used in metallographic studies on these alloys are described. Understanding of the properties of these alloys may lead to wider practical applications of them.
