Abstract The weathering of sedimentary rocks in high‐elevation catchments influences freshwater quality and the global carbon cycle. While individual biogeochemical mechanisms involved in this process are relatively well understood, quantifying their contributions to solute export and carbon fluxes under natural, transient conditions remains ...

Use of Goethite as an anti-corrosive Pigment [PDF]
Carbon steel is widely used as a metallic material, despite its limited corrosion resistance. To enhance its anti-corrosion properties, organic coatings such as epoxy are commonly applied due to their barrier mechanism.

The Stability of Gyrolite and Influence of Fe(III)
ABSTRACT Gyrolite (Ca4Si6O15(OH)2·4H2O) is a crystalline calcium silicate hydrate which forms hydrothermally and is primarily used as an adsorbent for wastewater treatment. The stability of gyrolite is poorly understood, as well as the potential impact of Fe, which can be present as an impurity in the raw materials used.

Nematic order of model goethite nanorods in a magnetic field [PDF]
We explore the nematic order of model goethite nanorods in an external magnetic field within Onsager-Parsons density functional theory. The goethite rods are represented by monodisperse, charged spherocylinders with a permanent magnetic moment along the ...

The removal of the As(V) and Iprodione fungicide onto EGS@APTES-GT, obtained by amino-modified expanded glass spheres (EGS) modified with goethite, was studied in this work. Material characterization was performed using SEM/EDS, XRD, and FTIR techniques.

Effects of Flavin-Goethite Interaction on Goethite Reduction by Shewanella decolorationis S12
Flavin mononucleotide (FMN) and riboflavin are structurally similar flavins, except for the presence of a phosphate group on the FMN molecule. They are used by a variety of electroactive bacteria as extracellular electron shuttles in microbial Fe ...

ABSTRACT The use of laterite soil with high Al and Fe content has been investigated as a novel supplementary cementitious material (SCM) to replace traditional mineral materials for clinker substitution. High‐energy ball milling was used to mechanochemically activate laterite and change its reactivity.

Phyllosilicate-based adsorbents decorated with iron oxyhydroxides: Application for lead, chromates and selenites removal [PDF]
Expanded vermiculite (EVer) was acid activated and silanized in order to obtain suitable substrate’s surface for decoration with iron oxyhydroxides (IO).
