Si-P impure Al-Goethite Mineralization on the island of Dugi Otok (Central Adriatic, Croatia) [PDF]

open access: yesGeologia Croatica, 2008
At the western seaward coast of the island of Dugi Otok, unusual goethite mineralization occurs as the infilling of a system of thin crevices in the Upper Cretaceous limestones of the Adriatic carbonate platform.

Effects of Flavin-Goethite Interaction on Goethite Reduction by Shewanella decolorationis S12 [PDF]

open access: yesFrontiers in Microbiology, 2019
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 ...

Phosphate sorption by goethite and kaolinite-goethite (k-g) system as described by isotherms

open access: yesCommunications in Soil Science and Plant Analysis, 1998
Goethite and kaolinite are active sorbents in soils and sediments. Unfortunately measuring their phosphate sorption capacity is difficult, because of the relatively low proportion of these clay minerals in many natural mixtures and the difficulties ...

A study of sorption of cadmium by goethite in aqueous solution

open access: yesBulletin of the Chemical Society of Ethiopia, 2002
Investigation has been carried out on the potential of a locally sourced goethite for the removal of cadmium ion from aqueous solutions using batch equilibration technique. The maximum uptake of cadmium is 6.4  10-2 mg/g-goethite.

Metal Oxides Catalyze Formation of Dehydroamino Acids by Phosphate β-Elimination Under Physiological Conditions. [PDF]

open access: yesAngew Chem Int Ed Engl
Dehydroamino acids (DHAA) are atypical electrophilic sites that lead to crosslinked proteins in Alzheimer's disease (AD) brains. No catalyst for their formation has been known in humans. We report that metal oxides catalyze β‐elimination of phosphoserine and phosphothreonine in model peptides at pH 7.5°C and 37°C, yielding DHAAs.

A Qualitative Examination of the Iron Boomerang and Trends in Spectral Metrics across Iron Ore Deposits in Western Australia

open access: yesApplied Sciences, 2022
There are two major types of iron ore deposits in the Pilbara Province of Western Australia—banded iron formation (BIF)-hosted iron ore deposits and bedded iron deposits (BID), respectively, named martite–goethite and martite–microplaty hematite and the ...
