Patent number: 8550698Abstract: Methods and systems for enhancing fluidization of nanoparticle and/or nanoagglomerates and for mixing and blending 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.Type: GrantFiled: November 9, 2007Date of Patent: October 8, 2013Assignees: Orion Engineered Carbons GmbH, New Jersey Institute of TechnologyInventors: Robert Pfeffer, Jose A.

Patent number: 7905433Abstract: Systems and methods for fluidization of particle and/or powder systems with reduced generation of static electricity are disclosed. The systems/methods are particularly advantageous for fluidization of nanoparticle and/or nanopowder systems, where the generation and/or presence of static electricity is a significant fluidization issue. The systems and methods generally involve the addition of an alcohol or other solvent to a fluidization gas to be introduced to the fluidization chamber, e.g., by bubbling the fluidization gas through a volume of solvent/alcohol, to advantageously reduce the build up of electrostatic charge. Systems and methods for capturing in-situ images within a fluidized bed are also provided that involve reducing the electrostatic charges generated within the fluidized bed and introducing a particle vision and measurement (PVM) probe to the fluidized bed for image capture.Type: GrantFiled: June 20, 2008Date of Patent: March 15, 2011Assignee: New Jersey Institute of TechnologyInventors: Robert Pfeffer, Jose A.

Patent number: 7658340Abstract: 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.Type: GrantFiled: November 28, 2006Date of Patent: February 9, 2010Assignee: New Jersey Institute of TechnologyInventors: Robert Pfeffer, Caroline H.

Patent number: 7645327Abstract: 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.Type: GrantFiled: May 2, 2006Date of Patent: January 12, 2010Assignee: New Jersey Institute of TechnologyInventors: Robert Pfeffer, Rajesh Dave, Stanislav Dukhin, Jose A.

Publication number: 20060086834Abstract: 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.Type: ApplicationFiled: July 27, 2004Publication date: April 27, 2006Inventors: Robert Pfeffer, Caroline Nam, Rajesh Dave, Guangliang Liu, Jose Quevedo, Qun Yu, Chao Zhu
