10 Apr 2011: Black blotches and streaks indicate magnetite [Fe-(II)Fe(III)2O4], a species of intermediate oxidation.

For example,much of the Fe appears to be in crystalline phases, whichinclude[4] magnetite (Fe3O4).

25 Apr 2024: We also work with Rich Harrison, making 3D reconstructions of magnetite and other nanoparticles, which have interesting magnetic properties as well as being tracers of particulate air pollution.
