The transfer gates 4 and the charge transfer gates 5 may be formed as MIS structures or as Schottky barrier structures using aluminium or platinum. Furthermore, the gallium arsenide substrate may be substituted for a silicon substrate. 

It should be pointed out here that all the platinum complexes which are active anticancer agents are also efficient inducers. Those complexes which are not active, do not cause lysis. So far, there is a complete isomorphism between the set of active anticancer complexes and the set of efficient inducers. Earlier, we had believed that a good correlation existed between anticancer active complexes and the filament-forming complexes. After a while, however, exceptions in both classes occurred which decreased our faith in this correlation. The correlation of lytic induction and anticancer activity has held up well. In fact, when R. Adamson at the National Cancer Institute reported the anticancer activity of gallium salts, we tested these and, indeed, they did induce lysis in lysogenic bacteria. 

It would appear from this patent literature that the development trends for PAFC cathode alloy electrocatalysts are from platinum, to Pt-refractory metal (vanadium) to Pt-Cr, to Pt-Cr-Co through to Pt-Fe-Co and then the various gallium additions to these combinations. It would seem, particularly in the case of gallium additions, that the gallium should induce porosity into the platinum alloys, since it would be expected to leach out easily.
