Wohlwill process Wohlwill process The Wohlwill process is an industrial-scale chemical procedure used to refine gold to the highest degree of purity (99.999%). The process was invented in 1874 by Emil Wohlwill. This electrochemical process involves using a cast gold ingot, often called a Doré bar, of 95%+ gold to serve as an anode. Lower percentages of gold in the anode will interfere with the reaction, especially when the contaminating metal is silver or one of the platinum group elements. The cathode(s) for this reaction are small sheets of pure (24k) gold sheeting or stainless steel. Current is applied to the system,
Social peer-to-peer processes in projects that in turn put their adapted source code in the public domain. The fifth requirement is cultural. The diffusion of mass intellectuality, (i.e. the distribution of human intelligence) and associated changes in ways of feeling and being (ontology), ways of knowing (epistemology) and value constellations (axiology) have been instrumental in creating the type of cooperative individualism needed to sustain an ethos which can enable P2P projects. There are two important aspects to the emergence of P2P in the economic sphere. On the one hand, as format for peer production processes, it is emerging as a 'third mode of
