  • Publication number: 20090272078
    Abstract: A method for packing and/or mixing particulate materials, e.g., aerogel particles, includes combining materials having different particle sizes and applying a negative pressure differential in the presence of a sound field. A negative pressure differential in the presence of vibration also can be used. The method increases mixing and packing density.

  • Publication number: 20070108320
    Abstract: With the coupling of an external field and aeration (or a flow of another gas), nanoparticles can be smoothly and vigorously fluidized. A magnetic force and/or pre-treatment may be employed with the fluidizing gas and, when coupled with a fluidizing medium, provide excellent means for achieving homogenous nanofluidization. The magnetic force interacts with non-fluidizing magnetic particles and helps to break channels as well as provide enough energy to disrupt the strong interparticle forces, thereby establishing an advantageous agglomerate size distribution. Enhanced fluidization is reflected by improved performance-related attributes. The fluidized nanoparticles may be coated, surface-treated and/or surface-modified in the fluidized state. In addition, the fluidized nanoparticles may participate in a reaction, either as a reactant or a catalyst, while in the fluidized state.

  • Publication number: 20060086834
    Abstract: With the coupling of an external field and aeration (or a flow of another gas), nanoparticles can be smoothly and vigorously fluidized. Multiple external fields and/or pre-treatment may be employed with the fluidizing gas: sieving, magnetic assistance, vibration, acoustic/sound or rotational/centrifugal forces. Any of these forces, either alone or in combination, when coupled with a fluidizing medium, provide excellent means for achieving homogenous nanofluidization. The additional force(s) help to break channels as well as provide enough energy to disrupt the strong interparticle forces, thereby establishing an advantageous agglomerate size distribution.

  • Patent number: 5772901
    Abstract: A method and an apparatus for separating a water/organic/solid emulsion, wherein the solid comprises particles having a length of about 50 .mu.m or less, are disclosed. The method comprises the steps of (1) directing the water/organic/solid emulsion from an emulsion source through a first hydrocyclone; (2) inverting the phase of the overflow emulsion from the first hydrocyclone; (3) directing the overflow emulsion through one or more subsequent hydrocyclones arranged in series; and (4) collecting the aqueous phase and the organic phase. The solid can be a biocatalyst, such as an intact bacterial, fungal or yeast cell. The organic phase is a liquid material substantially comprising carbon, which is substantially immiscible with water, such as petroleum.
