Abstract Zero-valent iron has been used for more than 130 years water treatment. It is based on redox reactions as well sorption to the corrosion products of iron. successfully applied removal metals and organic pollutants from groundwater wastewater. There are different variations how zero-valent can be used, especially (i) permeable reactive barriers, (ii) fluidized bed reactors (iii) nanosca...

Zero-valent iron nanoparticles (nano-Fe0) in aqueous solution rapidly inactivated Escherichia coli. A strong bactericidal effect of nano-Fe0 was found under deaerated conditions, with a linear correlation between log inactivation and nano-Fe0 dose (0.82 log inactivation/mg/L nano-Fe0 x h). The inactivation of E. coli under air saturation required much higher nano-Fe0 doses due to the corrosion ...

Using the chelating C,C′-bis(silylenyl)-ortho-dicarborane ligand, 1,2-(RSi)2-1,2-C2B10H10 [R=PhC(NtBu)2], leads to monoatomic zero-valent Ge complex (“germylone”) 3. The redox non-innocent character of carborane scaffold has a drastic influence on reactivity 3 towards reductants and oxidants. Reduction with one molar equivalent potassium naphthalenide (KC10H8) causes facile oxidation Ge0 GeI al...

BACKGROUND In a world of nanotechnology, the first concern is the potential environmental impact of nanoparticles. An efficient way to estimate nanotoxicity is to monitor the responses of bacteria exposed to these particles. OBJECTIVES The current study explored the antimicrobial properties of nZVI (zero-valent Iron nanoparticles) on the Gram-negative bacterial systems Erwinia amylovora, Xant...
