Wicken described this model of evolutionary complexification as a `teleomatic' process, meaning that the functional organization of living systems is ultimately an autocatalytic product of a `teleomatic drive' that arises from, or is `governed by', the `randomizing forces' of the entropy principle.
Several authors used this law to model epoxy resins polymerization [47-49] or silicone rubber vulcanization [50], because of the autocatalytic and catalytic nature of the reactions driving the crosslinking of these systems.
Developed by the Uyemura Central Research Lab in Hirakata, Japan, TWX-40 is a single immersion gold bath with autocatalytic capabilities that deposits 4-8 pin gold in a single step.
