== Desired diffusion ==

Diffusion transport facilitating [[self assembly]]. 
Important for the [[incremental path]]. 
Already placed parts sometimes coming loose again is often desirable such that errors can be fixed. 
Related: [[Kinetic trap]]s

== Undesired diffusion ==

Once assembled correctly one want's things to stick together as they are ans stay that way. 
Especially in [[direct path]] to [[gem-gum-tec]].

This is not so the case for [[pure metals and metallic alloys]] under specific circumstances. 
Specifically metal atoms like to diffuse …
* when there is an individual atom alone atop a surface
* at grain boundaries and at crystal defects where there are high strains and low transition energy barriers
* at non-cryogenic temperatures

This is one reason for why [[gem based APM]] focuses [[gemstone-like compounds]] rather than [[pure metals and metallic alloys]]. 
These materials avert surface diffusion at room temperature. 
Other reasons are
* circumventing the problem of [[oxidation]]
* their mechanical weakness compared to top gems
* their irreversible ductility (no clean binary detectible breaks)

* [[Diffusion slowdown blockade]]
* [[Self assembly]]
