Infiltration Magnetic

In the evaluation of papilledema, magnetic resonance imaging (MRI) or CT is an invaluable and necessary adjunct to determine whether there is a mass in the head or signs of meningeal involvement, which can occur with infection, tumor, or infiltration. MRI is especially sensitive in imaging the enlargement of the subarachnoid space... [Pg.365]

Besides the common features of most metal oxides as chemically stable and mechanically robust materials, this class of compounds can also provide unique functions for ceramics, high refractive index and magnetic materials, catalysis, and biocompatibility. A wide range of porous metal oxide materials have been synthesized over the last decade. In general three distinct pathways have been undertaken a sol-gel synthesis of the metal alkoxide infiltration with an appropriate metal salt and subsequent conversion or infiltration or codeposition with preformed metal oxide nanocrystals. [Pg.154]

Electron beams can be used for the probe which can analyze the micro portions of the sample s surface, ranging from nanometer to micrometer scales, because the electron beams can be easily narrowed by using the magnetic field. The infiltrated depth of the electron beams is usually smaller than that of the X-rays, suggesting that the electron beam analyses should be one of the best methods for surface analyses. [Pg.52]

Iron oxide nanoparticles are of particular interest due to their magnetic behavior (Gubin 2009) but also because of their low toxicity which renders them applicable in biomedicine (Roca et al. 2009). The infiltration of iron oxide nanoparticles into porous silicon which also is biocompatible (Canham 1995) results in a system of interest for magnetically guided drug delivery (Gu et al. 2010). [Pg.400]
