View source for Friction in diffusion transport

{{stub}}

One may also want to call this more fancily "energy dissipation in diffusion transport".

'''Diffusion transport is not free.''' <br> 
Just as in any type of transport there needs to be energy dissipated such that <br>
– there is a defined arrow of time <br> 
– there is a source and a target <br>

It is just that diffusion transport dissipates the energy not along the way but at the "toll stations". <br>
I soft nanotechnology that are typically cell membrane crossings or chemical transformations at sites fixed in space.

== The "change money" problem ==

As "toll stations" are not interconnected in soft nanosystems and molecules can only be used up in whole chunks, <br>
excess energy cannot be used to drive a reaction somewhere (somewhen) else. <br>
That is soft nanosystems do not provide the opportunity of [[dissipation sharing]].
