Polyphosphate (polyP), a polymer of orthophosphate (PO43-) of varying lengths, has been identified in all kingdoms of life. It can serve as a source of chemical bond energy (phosphoanhydride bond) that may have been used by biological systems prior to the evolution of ATP. Intracellular polyP is mainly stored as granules in specific vacuoles called acidocalcisomes, and its synthesis and ...

The ,acid, etching was conducted with different modes and different topologies of acids and bases but in the end the best results are obtained with nitric ,acid,. This choice was carefully evaluated also in function of the environmental impact because of the main drawback of this technology is that, however, we must eventually neutralize a residual ,acid, polluted in part by metals.
