Harnessing microbial subsurface metal reduction activities to synthesise nanoscale cobalt ferrite with enhanced magnetic properties (2009)
Journal Article
Coker, V. S., Telling, N. D., van der Laan, G., Pattrick, R. A., Pearce, C. I., Arenholz, E., …Lloyd, J. R. (2009). Harnessing microbial subsurface metal reduction activities to synthesise nanoscale cobalt ferrite with enhanced magnetic properties. Lawrence Berkeley National Laboratory,

Nanoscale ferrimagnetic particles have a diverse range of uses from directed cancer therapy and drug delivery systems to magnetic recording media and transducers. Such applications require the production of monodisperse nanoparticles with well-contro...

Biologically synthesized magnetite nanoparticles are studied using x-ray absorption and x-ray magnetic circular dichroism following exposure to hexavalent Cr solution. By examining their magnetic state, Cr cations are shown to exist in trivalent f...
