Abstract: New fluid separation devices and absorption materials are disclosed. Hollow fibers with an axial capillary slit act as very high efficiency absorption materials, as well as high-surface-area fluid separation devices. The hollow fibers with an axial capillary slit are constructed to preferentially absorb or repel different fluids and arranged to maximize that action over a plurality of fibers to separate different fluids. These separation devices can also function as injection devices and very effective micro-reactors.

Abstract: A liquid to solid material surface contact angle measurement system operating by way of detecting a transition in the behavior of a liquid sample with the solid material in a changing angular confinement environment along with use of a mathematical algorithm to then determine contact angle. Measurement of the angle at which the tested liquid transitions between apparent wetting and apparent non-wetting behavior, regardless of whether the liquid and solid material are truly classified as wetting or non-wetting, provides a measurement from which disclosed mathematical algorithms can predict the surface wetting characteristics of the liquid on the solid material. Automated performance of the confinement environment measurement and examples are included.

Abstract: Microdevices based on surface tension and wettability are useful as sensors, detectors, actuators, pumps, among other applications. As sensors and detectors they can respond to numerous stimuli such as pressure, temperature, gravity, rotation, acceleration, oscillation, chemical environments, magnetic fields, electric fields, radiation, and particle beams with a great choice of output options. Because of their design, they can be used in a broad range of temperatures and environments. Additionally, unlike other microsensors and detectors, these devices can be exposed to forces and pressures orders of magnitudes greater than their design limit and still return to their original accuracy and precision. These microdevices are also useful as actuators, pumps, valves and shutters. It is possible by joining these devices together to form complex devices that are able to control macroscopic flows for example. They are also able to perform complex electrical switching operations.

Abstract: In the present invention, a technique is described for manufacturing microtube devices which have peripheral geometries that are not uniform along the tube or device axis. These geometries may exist in only one location on the periphery of the microtube device or geometries may be repeated either uniformly or non-uniformly with micron or sub-micron precision along the tube or device axis. The preferred manufacturing process involves forming a complex mandrel, ie., (one, for example, that can not be formed by extrusion or pultrusion under constant processing conditions) and giving it at least one metallic and/or nonmetallic coating by any of a variety of techniques. The complex mandrel can then be removed by appropriate chemical or physical means that do not adversely affect the coating(s) desired for the wall. The result is a microtube structure having an axial profile duplicating that on the mandrel from which it was formed.

Abstract: This invention is a rapid low-cost technique for manufacturing thick high-performance carbon and ceramic composites in the form of uniformly densified near-net shaped structures. This is accomplished by impregnating composite preforms with low-viscosity wetting monomers which undergo polymerization followed by pyrolysis reactions in the preform ultimately creating ceramic and/or carbon matrices. Since the monomers possess low-molecular-weight they have low viscosities. Thus, if they wet the fiber and partially-densified preform they can easily impregnate even the smallest pores. Once inside the preforms, polymerization of the monomers is then initiated, resulting in a liquid matrix-precursor of the high molecular weight needed to produce a superior matrix (upon pyrolysis) with high efficiency.

Abstract: The invention comprises devices composed of at least one microscopic hollow tube having a wall of single or multiple layers with a thickness of at st one nanometer and a diameter of at least 5 nanometers. The walls of the tubes can be formed from a wide variety of materials, some of the preferred materials include metals, polymers, carbon, ceramics, glasses. If the space between the tubes is filled, the tubes become channels in a monolithic or composite body. The channels can have a random or ordered orientation. The interior of the tube walls can be coated with a desired material such as a catalyst and also may have depressions or elevations therein that were imparted to the fibers upon which the tubes are formed. The wall layers may be porous for the purpose of removing the fiber therethrough. Microtubes and microtube devices may be interfaced with the macroscopic world in a number of ways. Further the hollow tubes can be used to form rods or filaments in any desired configuration after the tube walls of a filled tube are removed.
