Sound velocity study of natural orthopyroxenes with varying iron content
Determination of the acoustic wave velocities of orthopyroxene as a function of composition is essential to identify the underlying causes of seismic heterogeneity. Such laboratory measurements are essential to determine the structure, composition and temperature variability of the upper mantle. …

Effect of iron content on electrodeposited Fe-MnOx catalysts for water oxidation
MnOx materials are earth-abundant and known to be efficient catalysts for the water oxidation reaction (WOR). I present the exploration of an optimal method of cathodically electrodepositing MnOx catalysts on an FTO substrate, allowing for quick synthesis and a homogeneous coverage of the …

Preparation of glass-ceramics largely using steelmaking slags and study on the effect of iron content on properties of glass-ceramics
… using steelmaking industry waste containing high iron content based on powder sintering and crystallization method. Anthracite was used in varying amounts as the reducing agent to recover iron in raw materials. X-ray diffraction analysis (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and …

The atomic and magnetic structures of several iron-substituted rare-earth manganese germanides and stannides
… for the non-substituted samples and the iron-containing samples, respectively. Iron randomly replaces manganese on all sites in both germanides and stannides. The a, b, and c lattice parameters decrease with increasing iron content for all samples. The net magnetization decreases with …

The Effect of Cations on Volatile Solids Destruction, Odors, and Dewatering in anaerobic digestion
… compounds generation increased proportionally as iron content in influent increased. However, they decreased as aluminum content in influent increased. It was also found that as iron content in influent increased, higher optimum polymer dose was required for dewatering. On the contrary, increase …

Feasibility study to extract iron and chromium from chromium contaminated soils
… and hazardous hexavalent chromium, contain high iron concentrations. At some sites, concentrations of iron oxide are higher than 30%. Both iron and chromium in soils have recyclable value provided they can be either concentrated in the oxide form or separated as metal. The concentrated oxide can …

Accumulation Of Subcortical Iron As A Modifier Of Volumetric And Cognitive Decline In Healthy Aging: Two Longitudinal Studies
<p>Accumulation of non-heme iron in the brain has been theorized as a cellular mechanism underlying global neural and cognitive decline in normal aging and neurodegenerative disease. Relatively few studies of brain iron in normal aging exist and extant studies are almost exclusively …

The effect of two reheating methods and storage on the development of warmed-over flavor in precooked chicken parts
… did not have a significant effect on the nonheme iron content of breasts or legs. The effects of heating temperature were inconsistent for the legs and breasts which was attributed to the different initial iron content of the legs, and the release of nonheme iron during the initial processing of …

Elucidation Of The Functional Role Of Pcbp-The Cytosolic Iron Chaperone Protein Family, In Cellular Iron Homeostasis
<p> <i> Biological Role of Ferritin </i> - Iron is essential for life and often utilized as a cofactor in many proteins. In humans, iron accumulation causes cirrhosis, arthritis, cardiomyopathy and diabetes mellitus, and it is associated with increased risk of cancer and heart disease. In contrast, …

Calibrating NMR response to capillary pressure curves in fine grained lithologies: Pretty Hill Formation, Otway Basin
… Study conclusions are that T2 response in high iron content rock is affected by many factors such as magnetic susceptibility, surface relaxivity and aspect ratio. Therefore, using the NMR response to estimate capillary displacement pressures in iron-rich, fine grained rocks is not recommended. …
