Magnetic resonance (MR) is based on the principle that nuclei of elements with an odd number of protons and neutrons spin and behave as magnets. When they are placed in a strong magnetic field, these nuclei align themselves in relation to the field. Ifradiowaves with a frequency specific to the nucleus and strength of the magnetic field (resonant frequency) is applied, some of the nuclei will a...

Three solutions of an ionic liquid ferrofluid (ILFF) using 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-NTf2) as the carrier liquid were emitted from a capillary electrospray source and the resulting beam was measured using a time-of-flight mass spectrometer (TOF-MS). The solutions had 3.04, 5.98, and 8.80 wt% iron oxide nanoparticles making them susceptible to magnetic f...
