Iron oxide was formed as -Fe 2 O 3 instead of the commonly formed magnetite nanoparticles (Fe 3 O 4) or a mixture of magnetite (Fe 3 O 4) and maghemite ( -Fe 2 O 3 cubic). The obtained particles of Fe 2 O 3 have size from 15 to 42 nm. The synthesized nanoparticles were characterized by XRD TGA/DTA magnetic susceptibility and TEM.

Magnetotactic bacteria (or MTB) are a polyphyletic group of bacteria that orient themselves along the magnetic field lines of Earth s magnetic field. Discovered in 1963 by Salvatore Bellini and rediscovered in 1975 by Richard Blakemore this alignment is believed to aid these organisms in reaching regions of optimal oxygen concentration. To perform this task these bacteria have organelles

Oxides are ubiquitous. The Earth s crust and mantle are largely made up of compounds of metal cations and oxygen anions. Looking at the composition of the crust in Figure 1.1 we see that oxygen is the most abundant element and the most common metals are aluminum and silicon. Most rocks are therefore aluminosilicates. The next most abundant element and the only transition metal other than
