: During the reporting period the development of the ionic liquid ferrofluid \201ILFF\202 based on EMIM-NTf2 was continued. The stabilizer anchoring group was changed from the bulky poly acryloxyethylphosphate to a less bulky poly acrylic acid based group, simplifying the synthesis and allowing the overall polymer content of the ILFF to be reduced. Supply of this ILFF was maintained to Brad King at Michigan Tech. We have also extended our collaboration to include Professor Juan Fernandez de la Mora of Yale University, for whom we designed and prepared an ethylammonium nitrate \201EAN\202 miscible ferrofluid based on the high-boiling-point solvent sulfolane. As part of this collaboration we have also been investigating new ferrofluids based on other high-boiling solvents.
