Ferric/ferrous determinations in synthetic biotite
… to 51 bars (at T = 750°C, P<sub>T</sub> = 1 kb). Ferrous iron contents of the annealed biotites were determined by wet chemical analyses. Total iron was determined by microprobe analyses to be equal to the stoichiometric values. The data confirm the predictions of Hazen and Wones (1972, 1978) …

Comparing Ferrous Chloride and Ferrous Sulfate as Secondary Coagulants at the Beaver Water District Drinking Water Treatment Plant
… a regulated inorganic DBP, BWD incorporated ferrous salt into their coagulation regime to quench chlorite to chloride. In this study, two ferrous salts - ferrous chloride (FC) and ferrous sulfate (FS) - were compared as secondary coagulants in combination with alum, the primary coagulant. …

High-rate centreless grinding of ferrous components.
… investigating plunge feed centreless grinding of ferrous components was undertaken. Results from approximately 300 grinding experiments were used to establish a data bank of grinding parameters for a range of grinding conditions. High-rate centreless grinding has been shown to be a feasible first …

Microstructure -Level Machining Modeling of Ferrous Alloys
The microstructure-level model was validated on machining of ductile iron and two of its constituents: pearlite and ferrite. Orthogonal cutting experiments and simulations were conducted of the three materials. The measured chip morphology and machining forces were compared with the model …

Ferrous futures : scenario planning for global steel
2 trillion kilograms of steel are produced around the world on an annual basis, enough to construct 17,000 Birds Nest Stadiums, 31,000 Empire State Buildings, or 480,000 Guggenheim Bilbao skeletons. If all of this steel were to fill Central Park, this single ingot would be nearly 10 meters tall. If …

Modeling Groundwater Denitrification by Ferrous Iron Using PHREEQC
… of two reasons: 1) the geochemical evidence for ferrous iron is more difficult to decipher due to the precipitation of Fe(III)-oxyhydroxides from the aqueous solution. 2) in the event when denitrification by both Fe(II) and organic carbon gave rise to precipitating reaction products, the role of …

Mössbauer investigations of high-spin ferrous heme proteins
… heme proteins containing iron in the high-spin ferrous state is discussed. Paramagnetic hyperfine interactions, induced by strong applied magnetic fields, result in Mössbauer spectra that contain a wealth of information about the symmetry of the active site iron atomo Quantitative evaluation of …

Electron paramagnetic resonance of myoglobin and related ferrous complexes
… EPR signals arise from the biologically active ferrous deoxyMb and photolyzed oxyMb, Mb""(2) complexes. Similar EPR signals were also discovered in photolyzed carbonmonoxy Mb, Mb*(CO), and from a model heme complex. The EPR signals in this work are from non-Kramers doublets which are not usually …

Improved Strategies for Dollar Spot Suppression Using Ferrous Sulfate
… disease. Previous research has demonstrated that ferrous sulfate applied at 48.8 kg ha-1 suppresses dollar spot epidemics without traditional fungicides. In vitro studies showed 100 to 1,000 mg kg-1 of ferrous sulfate directly suppressed S. homoeocarpa growth of an isolate collected from an …

HIGH TEMPERATURE KINETICS OF PRECIPITATION AND DISSOLUTION OF FERROUS-CARBONATE
Ferrous carbonate has been studied in batch reactions under rigorously anoxic conditions to determine thermodynamic and kinetic information about the compound. This information is particularly of interest in corrosion control and in the comparison of FeCO$\sb3$ to CaCO$\sb3$, a compound which has …

Experimental Study of Tricritical Phenomena in the Metamagnet Ferrous-Chloride
The magneto-optical rotation (theta)(,F) and heat capacity in constant applied field C(,H(,a)) have been simultaneously determined for the metamagnet FeCl(,2). Since (theta)(,F) is proportional to magnetization we are able, for the first time, to express both C(,H(,a)) and (theta)(,F) as functions …

The Formal Oxidation-Reduction Potentials of Ferric-ferrous in Phosphoric Acid
The formal redox potentials of the ferric-ferrous system have been determined in the media of perchloric (15), nitric (12), hydrochloric (13), sulfuric (15), and phosphoric (l) acids. The acids are named in the order of increasing extent to which the oxidation potential of the ferric-ferrous system …

Experimental study of tricritical phenomena in the metamagnet ferrous chloride (FeCl₂)
The magneto-optical rotation OF and heat capacity in constant applied field CHa have been simultaneously determined for the metamagnet Ha FeC12, Since OF is proportional to magnetization we are able, for the first time, to express both CHa and OF as functions of internal magnetic field along …
