Coatings for well screens that protect the screens from damage as they are inserted into the wellbore and once in the well, release reactive materials to react with and degrade potentially plugging materials such as drill solids, fluid filtercakes, fluid loss additives, and drilling fluids. The coatings can be specifically designed for individual well conditions and are comprised of a binder that either melts or dissolves within the wellbore and one or more reactive materials such as acids, enzymes, surfactants, chelants, oxidizers or free radical generators and the like which are released into the screen and the near wellbore area and which are effective in degrading or dissolving materials which could potentially plug the screen.

The present invention facilitates the specification and distribution of templated content materials by a content provider over an information exchange network such as the Internet. The present invention incorporates a system for managing inventories of graphical elements and their relationships to pre-defined page templates. A database capable of keeping track of users and their corresponding access privileges within the system is employed to monitor user activity. Ultimately, through the use of a software component delivered over the Internet for use within standard web browsers, end-users are able to populate templates under the constraints imposed by the rules of the manufacturers at the time of template design. These population elements which “fill in the blanks” of the pre-defined templates may be either of type IMAGE or TEXT. Image regions are populated by choosing from a subset of the entire image inventory, while TEXT types can be completely free form, with specific rules guiding justification, point size, font, and leading, or “fill in the blank” form with the same constraint rules as free form. Once the end user has met all of the criteria for a fully populated template, the system provides sophisticated means for downloading a high resolution file (such as a print-ready file or other file representation of the composed publication) which encapsulates all resources needed (layout, images, fonts, and constraint geometries) to fulfill the requirements of the publication. The downloaded file may be printed or published by electronic transfer, e.g., to a publisher for printing of the actual publication.

The LUMO level of the first organic compound is lower than the LUMO level of the second organic compound. The HOMO level of the first organic compound is lower than the HOMO level of the second organic compound. The HOMO level of the guest material is higher than the HOMO level of the second organic compound.

Silicon composite particles are prepared by sintering primary fine particles of silicon, silicon alloy or silicon oxide together with an organosilicon compound. Sintering of the organosilicon compound results in a silicon-base inorganic compound which serves as a binder. Each particle has the structure that silicon or silicon alloy fine particles are dispersed in the silicon-base inorganic compound binder, and voids are present within the particle.

A method for providing for thermal conduction using an array of carbon nanotubes (CNTs). An array of vertically oriented CNTs is grown on a substrate having high thermal conductivity, and interstitial regions between adjacent CNTs in the array are partly or wholly filled with a filler material having a high thermal conductivity so that at least one end of each CNT is exposed. The exposed end of each CNT is pressed against a surface of an object from which heat is to be removed. The CNT-filler composite adjacent to the substrate provides improved mechanical strength to anchor CNTs in place and also serves as a heat spreader to improve diffusion of heat flux from the smaller volume (CNTs) to a larger heat sink.

The invention provides a method for producing liquid hydrocarbons by first generating in a pressure swing reformer a synthesis gas stream having a mole ratio of H₂:CO greater than 2:1. Then, a portion of the hydrogen is separated to produce a synthesis gas stream having a mole ratio of H₂:CO of about 2:1 which steam is then introduced into a hydrocarbon synthesis reactor for conversion to liquid products.

An artificial electro-ferromagnetic meta-material demonstrates the design of tunable band-gap and tunable bi-anisotropic materials. The medium is obtained using a composite mixture of dielectric, ferro-electric, and metallic materials arranged in a periodic fashion. By changing the intensity of an applied DC field the permeability of the artificial electro-ferromagnetic can be properly varied over a particular range of frequency. The structure shows excellent Electromagnetic Band-Gap (EBG) behavior with a band-gap frequency that can be tuned by changing the applied DC field intensity. The building block of the electro-ferromagnetic material is composed of miniaturized high Q resonant circuits embedded in a low-loss dielectric background. The resonant circuits are constructed from metallic loops terminated with a printed capacitor loaded with a ferro-electric material. Modifying the topology of the embedded-circuit, a bi-anisotropic material (tunable) is examined. The embedded-circuit meta-material is treated theoretically using a transmission line analogy of a medium supporting TEM waves.

The present invention relates to a class of fluorescent, organic nanofibrils, and particularly the films comprising entangled piling of these nanofibrils exhibiting effective quenching of their fluorescence upon exposure the vapor of explosives. The invention also relates to a sensor and a method for sensing the explosives vapor and other volatile organic compounds, including the explosives taggants through the modulation of the fluorescence of the nanofibril film and the electrical conductivity of the nanofibrils. The invention also relates to a development of synthetic methods, protocols and techniques that leads to production of various arylene-ethynylene macrocycle (AEM) molecules, which consist of a shape-persistent, toroidal scaffold in planar conformation, with minimal ring strain and highly tunable ring sizes (from 0.5 nm to above 10 nm). The invention also relates to an approach to optimization of the one-dimensional molecular arrangement along the long axis of the nanofibril, which provides increased exciton (excited state) migration (via cofacial intermolecular electronic coupling) and charge transport (via pi-electronic delocalization). A combination of long-range exciton migration and efficient charge transport makes the nanofibrils ideal as sensory materials for detecting explosives and other volatile organic compounds through both optical and electrical sensing mechanisms.
