    • This invention relates generally to a method for controlling the pore size, pore size distribution and porosity of aluminum-oxide based ceramics through the choice of substituents on carboxylate-alumoxanes and aluminum-oxide nanoparticles. The method allows for the formation of intra-granular pores in the nanometer range to be created in alumina and aluminum oxide ceramic bodies. The control over pore size and pore size distribution is accomplished through the use of different chemical substituents on the carboxylate-alumoxanes and aluminum-oxide nanoparticles. The size and distribution of pores within the alumina-oxide ceramic are dependent on the identity of the carboxylate substituents. In particular the formation of intra-versus inter-granular porosity is dependent on the identity of the carboxylate substituents. The invention also provides methods for the manufacture of ceramic coatings on ceramic and carbon fibers for composite applications and ceramic membranes with nanometer sized pores. The pore size, pore size distribution and porosity, and hence the strength, permeability and surface adhesion, of the ceramic coating is controlled by the choice of substituent on the carboxylate-alumoxane. Thermolysis of self supporting spun layers of the carboxylate-alumoxanes results in disks of alumina with controlled pore size, pore size distribution and porosity. In an alternative method a porous substrate is dipped or coated with a solution of the carboxylate-alumoxane, followed by thermolysis to produce a composite membrane.
    • 本发明一般涉及通过选择羧酸盐 - 铝氧烷和氧化铝纳米颗粒上的取代基来控制氧化铝基陶瓷的孔径,孔径分布和孔隙率的方法。 该方法允许在氧化铝和氧化铝陶瓷体中形成纳米范围内的颗粒内孔。 通过在羧酸盐 - 铝氧烷和氧化铝纳米颗粒上使用不同的化学取代基来实现孔径和孔径分布的控制。 氧化铝 - 氧化物陶瓷内的孔的大小和分布取决于羧酸盐取代基的同一性。 特别地,孔内和颗粒间孔隙度的形成取决于羧酸盐取代基的同一性。 本发明还提供了用于复合应用的陶瓷和碳纤维上的陶瓷涂层的制造方法以及具有纳米尺寸孔的陶瓷膜。 陶瓷涂层的孔径,孔径分布和孔隙率以及强度,渗透性和表面粘附性由羧酸铝 - 铝氧烷上的取代基的选择来控制。 羧酸铝铝氧烷的自支撑纺丝层的热解产生具有可控孔径,孔径分布和孔隙率的氧化铝盘。 在另一种方法中,多孔基材浸渍或涂覆有羧酸盐 - 铝氧烷的溶液,然后进行热分解以产生复合膜。

    • A transport of plasmonic particles through a mineral formation is analyzed by flowing a plasmonic particles solution through an immobile phase (e.g., a mineral formation), determining an absorbance of the plasmonic particles solution subsequent to flowing the plasmonic particles solution through the immobile phase, comparing the determined absorbance of the plasmonic particles solution with an absorbance of the plasmonic particles solution determined previous to flowing the plasmonic particles solution through the immobile phase, and determining an absorbance of the plasmonic particles to the immobile phase as a function of the comparison. The plasmonic particles solution may be produced by dissolving or suspending plasmonic particles in a mobile phase. Flowing the plasmonic particles solution through the immobile phase may include injecting the plasmonic particles solution into the immobile phase, and then flushing the plasmonic particles solution through the immobile phase.
