摘要： A method for removing a contaminant from a fluid system comprises contacting the fluid system with an inversely fluidized material, for example a particulate aerogel, thereby removing at least a portion of the contaminant from the fluid system. The method can be used to remove oil or other organic materials from wastewater streams. It can be conducted in a fluidized bed, which includes nanoporous particles and a fluidizing medium, wherein the nanoporous particles have a density lower than that of the fluidizing medium.

摘要： Methods and systems for enhancing fluidization of nanoparticle and/or nanoagglomerates and for mixing nanoparticle/nanoagglomerate systems at the nanoscale are provided. A fluidization chamber is provided with a fluidizing medium (e.g., a fluidizing gas) directed in a first fluidizing direction, e.g., upward into and through a bed containing a volume of nanoparticles and/or nanopowders. A second source of air/gas flow is provided with respect to the fluidization chamber, the secondary air/gas flow generally being oppositely (or substantially oppositely) directed relative to the fluidizing medium. Turbulence created by the secondary gas flow, e.g., a jet from a micro-jet nozzle, is advantageously effective to aerate the agglomerates and the shear generated by the jet is advantageously effective to break apart nanoagglomerates and/or reduce the tendency for nanoagglomerates to form or reform. A downwardly directed source of secondary gas flow located near the main gas distributor leads to full fluidization of the entire amount of powder in the column. In addition, the oppositely directed fluid flow facilitates powder circulation within the fluidization chamber, thereby enhancing fluidization and mixing/blending results.
摘要翻译：提供了用于增强纳米颗粒和/或纳米团聚物的流化和用于在纳米尺度上混合纳米颗粒/纳米颗粒体系的方法和系统。流化室设置有以第一流化方向（例如向上）引导入并穿过含有一定体积的纳米颗粒和/或纳米粉末的床的流化介质（例如，流化气体）。相对于流化室设置第二气/气流源，二次空气/气体流通常相对于流化介质相反（或大致相反地）流动。由次级气流产生的湍流，例如来自微喷嘴的射流，有利于使附聚物充气，并且由射流产生的剪切有利于有效地分离纳米团聚体和/或降低纳米颗粒形成的趋势或改革。位于主气体分配器附近的向下定向的二次气流源导致柱中全部粉末的充分流化。此外，相反导向的流体流动促进流化室内的粉末循环，从而增强流化和混合/混合结果。

摘要： Systems and methods for achieving filtration are provided that utilize agglomerates or granules of nanoparticles. The agglomerates or granules of nanoparticles may be used as and/or incorporated into a HEPA filtration system to remove solid or liquid submicron-sized particles, e.g., MPPS, in an efficient and efficacious manner. The filtration systems and methods are provided that utilize agglomerates or granules in a size range of about 100- 500 microns. The agglomerates or granules of nanoparticles exhibit a hierarchical fractal structure. In the case of agglomerates of nanoparticles, porosities of 0.9 or greater are generally employed, and for granules of nanoparticles, porosities that are smaller than 0.9 may be employed. Filter media formed from the agglomerates or granules may be formed from materials such as carbon black and fumed silica, and may be employed in baffled or non-baffled filtration apparatus.
