Plasmid, 27(1), 72-79 (1992-01-01)
Germanium is an inert metal with no known biological function in prokaryotic or eukaryotic organisms. Its toxicity is low compared to that of silver. Germanium is accumulated in certain bacterial strains by either energy-independent passive binding or an energy-dependent mechanism.

ACS applied materials & interfaces, 7(27), 14644-14653 (2015-06-18)
Thin-film composite membranes, primarily based on poly(amide) (PA) semipermeable materials, are nowadays the dominant technology used in pressure driven water desalination systems. Despite offering superior water permeation and salt selectivity, their surface properties, such as their charge and roughness, cannot
