In this study we used in situ synchrotron-based energy dispersive X-ray diffraction (EDXRD)
to follow the transformation of ferrihydrite to hematite at pH∼ 8 and ionic strength between …

The effect of the presence of soluble silicates on ferrihydrite precipitation and some
properties of the products formed in co-precipitation of ferrihydrite and silica have been …

Abstract Scorodite (FeAsO 4· 2H 2 O)–water interaction is critical to As distribution and
storage in surface environment but is inadequately understood due to ambiguities in the …

Mine permitting requires an analysis of reasonably foreseeable impacts. In pit lake models,
precipitates may be invoked to reduce dissolved aqueous concentrations, and thereby …

Iron-intercalated clay has been obtained starting from a natural bentonite-type clay sample
from Maghnia (Algeria). The natural compound contained, besides the clay material …

Mobile inorganic and organic nanocolloidal particles originate-from and interact-with bulk
solid phases in soil and sediment environments, and as such, they contribute to the dynamic …

The reactivity of soils and sediments is often described by parameters such as the specific
surface area (SSA) and the cation exchange capacity (CEC). Both, however, are bulk values …

Magnetite being a magnetic semiconductor has a large scope of applications in
biomedication, catalysis, sensors, and magnetic devices. For various applications, one …

We have developed a new aqueous-phase synthesis of highly crystalline
superparamagnetic magnetite nanoparticles using mechanochemical effects under …

In recent years, the depletion of high-grade deposits of precious metals such as gold and
silver has led to the development of refractory ores that often contain metalloids such as …
