Near the Ferric Pseudobrookite Composition (Fe2TiO5)

Structure and Magnetic Properties of Nanocomposite Fe2O3/TiO2 Catalysts Fabricated by Heterogeneous Precipitation

The aim of our work is to study phase composition, particle size and magnetic response of Fe2O3/TiO2 nanocomposites with respect to the final annealing temperature. Those nanomaterials are considered as smart catalysts, separable from a liquid/gaseous phase by applied magnetic field. The starting product was obtained by an ecologically acceptable route, based on heterogeneous precipitation of t...

Determining the Composition of Human Meniscus using Near Infrared Spectroscopy

Potential of Near-Infrared Reflectance Spectroscopy (NIRS) to Predict Nutrient Composition of Bromus tomentellus

Determination of forage quality of available species is one of the fundamentalfactors for the management of rangelands. Near-Infrared Reflectance Spectroscopy (NIRS)was used to analysis the Nitrogen (N), Acid Detergent Fiber (ADF), Dry MatterDigestibility (DMD) and Metabolizable Energy (ME) content of three phenological stages(vegetative, flowering and seeding) of Bromus tomentellus samples in ...

Oxygen isotopic composition of ferric oxides from recent soil, hydrologic, and marine environments

Low-temperature synthesis experiments on ferric oxide–water systems have resulted in disparate oxygen isotope fractionation–temperature (a-T) curves. In this study, recent ferric oxides, mostly goethites of Holocene age, were collected and analyzed from a variety of modern soil, stream, and marine environments, where formation temperature and the oxygen isotopic composition (dO) of the water fr...

EFFECT OF MECHANICAL ACTIVATION ON THE KINETICS OF LEACHINGOFCHALCOPYRITE IN THE FERRIC SULFATE MEDIA

Abstract: has been investigated. It has been shown that the mechanism of leaching reaction is diffusion through the product layerand does not undergo any change as a result of mechanical activation in a wide range of experimental conditions.Leaching rate is strongly influenced by milling intensity and the effect of ball to powder mass ratio is stronger thanmilling time. Curve fitting of experim...
