Eu3+ doped polyphosphate-aminosilane organic-inorganic hybrids
(Elsevier B.V., 2014)
Preparation of zinc sodium polyphosphates glasses from coacervates precursors. Characterisation of the obtained glasses, and their applications
(Elsevier B.V., 2002-12-01)
A soft chemistry route is described to obtain glasses in the P2O5-Na2O-ZnO-H2O. It is based on the addition of zinc salts to coacervates prepared from sodium polyphosphate. The processing of these coacervates leads to ...
Mechanism of the formation and properties of antimony polyphosphate
(2005-07-01)
Formation of antimony polyphosphate using Sb2O3 and/or (NH4)2HPO4 and NH4H 2PO4 as starting materials has been simulated by thermal analysis technique. The elimination of water and ammonia molecules induced by heating leads ...

Phosphate-enhanced stationary-phase fitness of Escherichia coli is related to inorganic polyphosphate level
(American Society for Microbiology, 2009-07)
We found that Escherichia coli grown in media with >37 mM phosphate maintained a high polyphosphate level in late stationary phase, which could account for changes in gene expression and enzyme activities that enhance ...
Copper tolerance mediated by polyphosphate degradation and low-affinity inorganic phosphate transport system in Escherichia coli
(BioMed Central, 2014-03)
Metal tolerance in bacteria has been related to polyP in a model in which heavy metals stimulate the polymer hydrolysis, forming metal-phosphate complexes that are exported. As previously described in our laboratory, ...
Aluminum polyphosphate nanoparticles: Preparation, particle size determination, and microchemistry

Non-crystalline aluminum polyphosphates: Preparation and properties
(Soc Brasileira QuimicaSao PauloBrasil, 1996)
Spectroscopic study and local coordination of polyphosphate colloidal systems
(Amer Chemical Soc, 2005-03-01)
The interaction between metaphosphate chains and the metal ions Ca2+ and Eu3+ has been studied in water by Eu3+ luminescence, infrared absorption, and P-31 NMR spectroscopy. Two main families of sites could be identified ...
