Hello, The following event may be of interest to you: Magentic Interactions on Iron Oxide Nanoparticles Tuesday, May 14, 2013 A lecture byThelma BerquoCandidate for the position in PhysicsI will report on the investigation of interactions of the antiferromagnetic iron oxide ferrihydrite by comparing magnetic properties of synthetic uncoated and coated nanoparticles. Four different coating agents (sugar, alginate, lactate and ascorbate) were employed to prepare sub-samples from the same batch of ferrihydrite, and both magnetic and non-magnetic techniques were used to characterize the samples. I will present results showing that coating agent caused a dramatic change in the magnetic properties of these nanoparticles. In addition, I will show how the results obtained from studying synthetic ferrihydrite can help us to better understand the magnetic properties of Fe microbial mat deposited on hydrothermal vents at Loihi Seamount (Hawaii).
