Samples prepared at pH = 9, 10, 11 from 1 M Fe solutions were dried on Kapton thin film and measured in transmission with a 100-μm-wide beam of 15 keV (λ = 0.82656 Å). Magnetite ...

A chunk of magnetite guards the office door ... a metal shed stuffed with stacks of long, thin cardboard boxes. Inside each box is a section of a core sample taken when the mine was first developed.

Magnetotactic bacteria (MTB) are phylogenetically and morphologically diverse prokaryotes that share an ancestral capability of producing intracellular magnetite (Fe 3 O 4) or/and greigite (Fe 3 S ...
