摘要:The present invention relates to a method of forming iron oxide nanoparticles comprising the steps of (a) suspending iron oxide/hydroxide and oleic acid or a derivative thereof in a primary organic solvent; (b) increasing the temperature of the suspension by a defined rate up to a maximum of 340° C. to 500° C.; (c) aging the suspension at the maximum temperature of step (b) for about 0.5 to 6 h; (d) cooling the suspension; (e) adding a secondary organic solvent; (f) precipitating nanoparticles by adding a non-solvent and removing excess solvent; (g) dispersing said nanoparticles in said secondary organic solvent; (h) mixing the dispersion of step (g) with a solution of a polymer; and (i) optionally removing said secondary organic solvent. The present invention further relates to an iron oxide nanoparticle obtainable by the method, the additional modification, encapsulation and decoration of such nanoparticles, as well as the use of the nanoparticles as tracers for Magnetic Particle Imaging (MPI), Magnetic Particle Spectroscopy (MPS).

标题 :Synthesis of large crystallite zeolites
发明人：DWYER FRANCIS G; CHU POCHEN; CORMIER JR WILLIAM E
权利人:MOBIL OIL CORP
摘要:The invention provides a method of making large crystallite zeolites by a method comprising forming the zeolite in a medium containing a combination of two different alkylammonium cations or a combination of an alkylammonium cation and a metallic cation. In the combination at least one of the cations will have an ionic radius of from about 1.40 to the pore size of the specific zeolite.

摘要:The synthesis of 4-, 4-(1,1)-and 3,5-substituted N-alkyl-pyridinium salts as well as of 2-carboxamide substituted N(1,4)diazinium compounds are described. The N-surfactants obtained have a small critical micelle concentration (CMC) of 10-5 -10-7 Mol/Liter. These surfactants produce micells of different size and form depending on the nature of the anions. 4-(1,1)-substituted and 3,5-substituted N-alkyl-pyridinium components are capable of forming vesicles in equeous solutions of different forms and sizes. The N-surfactants synthesized can be used as pharmaceuticals.

摘要:A process for the selective production of ethanol by vapor phase reaction of acetic acid over a hydrogenating catalyst composition to form ethanol is disclosed and claimed. In an embodiment of this invention reaction of acetic acid and hydrogen over either cobalt and palladium supported on graphite or cobalt and platinum supported on silica selectively produces ethanol in a vapor phase at a temperature of about 250° C.
