Gold Intensification

Most Intensification treatments accelerate development as well as increase the effective speed of the photographic material. The gold Intensification is especially notable in this respect, and is of interest in relation to the mechanism of development. A simple motion picture positive film responds well to the gold treatment, which consists simply in bathing the exposed film for a few minutes in a solution containing the aurous thiocyanate complex in the presence of excess thiocyanate and bromide ions. Figure 7 shows the developed densities for several...

Photolysis of [ReH Cdppe) ] in Degassed Solution. Irradiation of degassed benzene solutions of the complex with 366-nm light gives a color change from yellow to gold with a corresponding intensification and shift in the absorption maximum from 320 to 310 nm. In the IR, as the irradiation proceeds,... 

Excellent studies of the interaction of platinum compounds with biologically important small and macromolecular species have been reported both in this volume and elsewhere ( ) Consequences of these observations have been associated with proposed modes of antineoplastic action of cis-platinum (ll) compounds. The relatively recent discovery of this new class of antineoplastic agents ( ) has led to an intensification of research into the therapeutic potential of transition metal compounds. It is surprising that the intensity of scientific zeal directed towards this class of antineoplastic agents has not focused on gold compounds, probably one of the first metals to be used in treatment of...
