摘要:The present invention provides a method of synthesizing nanosized abrasive particles and methods of using the same in chemical mechanical polishing slurry applications. The nanosized abrasive particles according to the invention are produced by hydrothermal synthesis. The crystallites of the particles include cerium atoms and atoms of metals other than cerium. In a preferred embodiment of the invention, the crystallites exhibit a cubic crystal lattice structure. The differences in electric potential between the cerium atoms and the atoms of metals other than cerium facilitate the polishing of films without the need for chemical oxidizers.

摘要:High surface area, high entropy oxides comprising multiple metal cations in a single-phase fluorite lattice material enables intrinsic catalytic activity without platinum group metals, tunable oxygen storage capacity, and thermal stability. These properties can be obtained through a facile sol-gel synthesis to provide a low-temperature route for production of phase-pure multi-cationic oxides. The resulting materials achieved significantly higher surface area and catalytic performance, taking advantage of all the properties endowed by the various cations in the composition.

摘要:The methanol electro-oxidation catalysts include nano-oxides of rare earth metals (i.e., cesium, praseodymium, neodymium and samarium) and platinum nano-particles. The nano-oxides of the rare earth metals are dispersed during synthesis of a support material, preferably formed from mesoporous carbon. The platinum nano-particles form between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, the rare earth metal forms between about 10 wt % and about 15 wt % of the methanol electro-oxidation catalyst, and carbon and oxygen forming the balance (between about 70 wt % and about 80 wt %) of the methanol electro-oxidation catalyst.

标题:Solvothermal synthesis of metal alkanoate and metal oxide nanoparticles
发明人：Treadwell LaRico Juan; DAVIS-WHEELER CLARE
权利人:NAT TECH & ENG SOLUTIONS SANDIA LLC
摘要:A facile solvothermal method can be used to synthesize metal alkanoate nanoparticles using a metal nitrate precursor, alcohol/water, and alkanoic acid. The method can produce lanthanide (e.g., La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, or Yb) and transition metal (e.g., Ag, Co, Cu, or Pb) alkanoate nanoparticles (<100 nm) with spherical morphology. These hybrid nanomaterials adopt a lamellar structure consisting of inorganic metal cation layers separated by an alkanoate anion bilayer and exhibit liquid crystalline phases during melting. The metal alkanoate nanoparticles can be calcined to produce metal oxide nanoparticles.

摘要:A radiation shielding material for shielding against gamma radiation includes neodymium-doped zirconia nanoparticles in a matrix. The neodymium doped zirconia nanoparticles have a tetragonal crystal structure and an average size between about 25 nm to about 35 nm. The nanoparticles have a neodymium content in the range of about 1.5 mol % to about 3 mol % based on the total molar content of the zirconia nanoparticles. A method for the synthesis of neodymium-doped zirconia nanoparticles is provided. The method includes controlled metamorphosis of zirconia from monoclinic to tetragonal phase which results in a multifunctional shielding material having durability and high radiation absorption efficiency.
