A process for producing chlorine and iron oxide from iron chloride (which may be generated as a by-product of the direct chlorination of titaniferous ores) comprises the steps of converting ferrous chloride to ferric chloride by reaction with chlorine, separating the solids from the gaseous ...
DFT has also been used to calculate energies of structures for the singlet and triplet states of Fe(CO)3(η2-C3H6), either pseudo-axial or pseudo-equatorial isomers, and for three isomers of HFe(CO)3(η3-C3H5). This and other evidence suggest that the reaction (Equation (1)) is exp...

This view obviously degrades Fe0corrosion by water (Eq. 8) to a side reaction although water is the solvent ([H2O] = 55.5 mol L−1) and has been documented a stand-alone corrosive agent both in the open corrosion literature (Stratmann and Müller1994; Nesic2007; Alamilla et al.2009) ...
Iron is critical for host–pathogen interactions. While pathogens seek to scavenge iron to spread, the host aims at decreasing iron availability to reduce pathogen virulence. Thus, iron sensing and homeostasis are of particular importance to prevent host
In one of the solvate chloroform molecule, three chlorine atoms were found to be disordered over two positions with occupancy factors 0.86 and 0.14, respectively. These occupancies were established by free refinement of both positions in anisotropic refinement. Propeller-like disorder of the chlorine...
The traces of chlorine were present and may have been introduced possibly during the treatment with HCl while the Al and C originated from the WIF as impurities. Figure 7a(iii) shows the particle size distribution (PSD) of the hematite. The PSD indicates the dominance of particle size range ...
Polyether polyamino methylene phosphonates, when added to various industrial water systems in concentrations between 0.1 mg/L and 50 mg/L, stabilize soluble zinc, manganese and iron ions and their reaction products, in desirable forms and reduced particle sizes. In particular, this stabilization can...
Such a chloride ion-assisted formation mechanism was supported by finding the presence of a trace amount of chlorine on the octapod iron oxide nanoparticles using energy-dispersive X-ray spectro- scopy and X-ray photoelectron spectroscopy (Fig. 2e and Supplementary Fig. S6). To the best of our...
Pt- and Ir/Ru-oxide-based catalysts are the benchmark materials for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER)3,4,5,6. However, their high cost and poor stability limit large-scale utilization. Thus, it is crucial to fabricate highly efficient catalysts for electro...
