International Classification:

B04B 512

US Classification:

209725, 2091391, 209710, 209713, 209717, 209734

Abstract:

An apparatus for classifying a mixture of fine and coarse particles in a fluid stream by size or density comprises a housing, a boundary layer momentum transfer device, and an inlet flow control mechanism. The housing comprises an inlet, an interior chamber, and a fine particle outlet. The boundary layer momentum transfer device comprises a plurality of disks stacked in spaced, parallel relation in the interior chamber. The disks are rotatable about a disk axis. The disks have respective central openings cooperatively defining a plenum having a closed axial end and an opposing open axial end. The plenum communicates with spaces defined between each adjacent disk to cooperatively define a fine particle flow path from the interior chamber, through the spaces, through the plenum and the open axial end thereof, and to the fine particle outlet. The inlet flow control mechanism communicates with the interior chamber and provides an adjustable inlet flow path into the interior chamber. The housing can include a cylindrical, conical, and/or scroll-shaped profile.

Assignee:

University of Florida Research Foundation, Inc. - Gainesville FL

International Classification:

A61K 8/18

US Classification:

424 61

Abstract:

An electroless method of forming high aspect ratio metal particles includes the steps of mixing a metal or metal salt with at least one acid to form an acidified metal halide salt solution, and mixing the solution with a supersaturated sol to form a sol comprising solution. Metal cations provided by the acidified metal salt are reduced to form a plurality of high aspect ratio metal particles. Instead of using a sol, an organic compound can be oxidized to generate the reducing agent. A metal comprising particle assembly includes a plurality of high aspect ratio metal platelets having an aspect ratio of a major dimension averaging from 10 to 200 times a nanoscale minor dimension of the platelet. The platelets can be used for nail polish, eye liner or the cores for medical delivery vehicles.

Abstract:

A method for removing mercury from a fluid stream includes the steps of providing a porous composite material comprising a substrate and a plurality of catalyst and/or photocatalyst particles, and contacting substrate with a fluid stream. The porous composite material adsorbs and/or then oxidizes or reduces metallic species including elemental mercury. A fossil fuel fired power plant can include an emission control device comprising the porous composite material to filter flue gas to and thereby minimize mercury emissions into the environment.

Abstract:

An electromagnetic radiation activated device comprises a property changing material and at least one functionalized fullerene that upon irradiation of the functionalized fullerenes with electromagnetic radiation of one or more frequencies a thermally activated chemical or physical transformation occurs in the property changing material. The thermal activated transformation of the property changing material is triggered by the heating or combustion of the functionalized fullerenes upon their irradiation. The device can include a chemical agent that is embedded in the property changing material and is released when the material is heated by the functionalized fullerenes upon irradiation.
