Abstract:
The present invention is a fundamental method and apparatus of a microcomponent assembly that overcomes the inherent limitations of state of the art chemical separations. The fundamental element enabling miniaturization is the porous contactor contained within a microcomponent assembly for mass transfer of a working compound from a first medium to a second medium. The porous contactor has a thickness, and a plurality of pores extending through the thickness. The pores are of a geometry cooperating with a boundary tension of one or the other or both of the media thereby preventing migration of one, other or both through the microporous contactor while permitting passage of the working compound. In the microcomponent assembly, the porous contactor is placed between a first laminate such that a first space or first microplenum is formed between the microporous contactor and the first laminate. Additionally, a cover sheet provides a second space or second plenum between the porous contactor and the cover sheet.
Abstract:
A microcomponent apparatus for conducting unit operations comprising: a microcomponent device wherein, during operation, a stream enters the microcomponent device and a first unit operation is performed on said stream, said stream and exiting the microcomponent device; a processing device connected to the microcomponent device; said processing device being capable of modifying said stream by a second unit operation wherein, during operation, said stream re-enters said microcomponent device where said first unit operation can again be performed on the stream, and said stream exits the microcomponent device.

Abstract:
The present invention provides chemical reactors and reaction chambers and methods for conducting catalytic chemical reactions having gas phase reactants. In preferred embodiments, these reaction chambers and methods include at least one porous catalyst material that has pore sizes large enough to permit molecular diffusion within the porous catalyst material.
Abstract:
A micro-machined virtual impactor device to permit the separation, collection and concentration of a significant portion of environmental particulates having a diameter of less than ten microns. The device comprises a plurality of projection (12), each having a virtual impact surface that defines an aperture (30) in a stagnant zone of fluid flow. A major portion of the particulate material is concentrated into a minor portion of the fluid which is processed through the aperture, where it is collected for subsequent analysis.
