Enhanced fluidization of nanoparticle agglomerates
Gas fluidization of nanoparticle agglomerates has recently received much attention due to the excellent way in which these novel nanornaterials can be dispersed in a gaseous medium. Nanopowders have a very high surface area to volume ratio which allows them have unique chemical and physical …

Jet assisted fluidization of nanoparticle agglomerates
… operation used to disperse, handle and process nanoparticles, but due to the complications involved with achieving homogenous fluidization of the agglomerates of nanoparticles, several methods have been developed to assist their conventional mode of fluidization. In this work, the conventional …

Pure Insulin Nanoparticle Agglomerates for Pulmonary Delivery
… being within the respirable range. Insulin nanoparticles were produced by titrating insulin dissolved at low pH to the pI of the native protein, and were then processed into microparticles using solvent displacement. Particle size, crystallinity, dissolution properties, stability, and powder …

Enhancement of fluidization and filtration using nanoparticle agglomerates and aerogels
… have classified the fluidization behavior of nanoparticles as Agglomerate Particulate Fluidization (APF) and Agglomerate Bubbling Fluidization (ABE). These fluidization behaviors are quite different in regard to the fluidized bed expansion, the presence of bubbles and the smoothness of the bed …

Deagglomeration and mixing via the rapid expansion of high pressure and supercritical suspensions
… in the dry state and typically form large agglomerates, leading to a diminished surface area or even grain growth, which minimizes the effectiveness of these nanomaterials. This dissertation addresses the issue of mixing nanopowders constituents by deagglomerating them and achieving …

Characterization of redox active materials to enable electrochemical separations through faradaic deionization
… within porous electrodes comprised of NiHCFe nanoparticles, conductive carbon additives and polymer binder are investigated. A combination of experimental characterization, particle-scale transport modeling, and porous electrode theory show that slow electron conduction through nanoparticle …
