Current Ideas about Prebiological Compartmentalization

open access: yesLife, 2015
Contemporary biological cells are highly sophisticated dynamic compartment systems which separate an internal volume from the external medium through a boundary, which controls, in complex ways, the exchange of matter and energy between the cell’s ...

Increased power from a two-chamber microbial fuel cell with a low-pH air-cathode compartment [PDF]

open access: yes, 2009
Pt-supported air-cathodes still need improvement if their application in MFC technology is to be sustainable. In this context, the efficiency of an air-cathode was studied with respect to the pH of the solution it was exposed to.
