Accelerated Microbial Corrosion by Magnetite and Electrically Conductive Pili through Direct Fe0-to-Microbe Electron Transfer.

Angewandte Chemie, 2023
Electrobiocorrosion, the process in which microbes extract electrons from metallic iron (Fe0) through direct Fe0-microbe electrical connections, is thought to contribute to the costly corrosion of iron-containing metals that impacts many industries ...

Water-dispersible magnetite-reduced graphene oxide composites for arsenic removal.

ACS Nano, 2010
Magnetite-graphene hybrids have been synthesized via a chemical reaction with a magnetite particle size of approximately 10 nm. The composites are superparamagnetic at room temperature and can be separated by an external magnetic field.

Trace Element Composition of Igneous and Hydrothermal Magnetite from Porphyry Deposits: Relationship to Deposit Subtypes and Magmatic Affinity

Economic Geology, 2019
The trace element composition of igneous and hydrothermal magnetite from 19 well-studied porphyry Cu ± Au ± Mo, Mo, and W-Mo deposits was measured by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) and then classified by partial
