An enhanced four rank enabled buffer device that includes input ports for receiving input data that includes address and command data directed to one or more of up to four ranks of memory devices. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand and at least one electron donor ligand in the form of a heterocyclic group are used to catalyze cross-metathesis reactions to provide a olefin products that are directly substituted with an electron-withdrawing group. Next, a photoresist with patterns is formed on the surface of the mask layer. The elastomeric compositions are useful for producing films, fabrics, and laminates for use in a wide variety of personal care and medical articles.
