摘要： A new class of ordered functional nanoporous material (OFNMs) with a unique combination of electronic conductivity, gas transport ability, and ion transport properties are provided. The OFNM provided is highly ordered and contains nanometer scale pores lined with nitrogen atoms. The pores have dimensions of from 1.2 nm to 82 nm of longest linear extent across the pore. The functionality within the pore is controlled through selection of groups that extend into the pore. The degree of conjugated aromaticity is readily controlled to adjust the electrical conductivity properties of the resulting structure. By adjusting the groups external to the pore, three-dimensional structures are formed that are organic mimics of zeolites, metal organic frameworks (MOF), or perovskites.

摘要： Methods of natural gas production and carbon sequestration are provided. The method includes delivering a feedstock downhole to a coal reservoir, generating biogas within the coal reservoir, and harvesting the biogas. Another method for tracing the migration of biogas in a coal reservoir includes delivering a feedstock downhole to a coal reservoir, generating biogas that is isotopically differentiable from a background gas within the coal reservoir through microbial action, harvesting the biogas, analyzing the biogas from the coal reservoir at the injection well and at one or more offset wells within the same coal reservoir, detecting the biogas at the offset wells using isotopic differentiation, and mapping the migration of the biogas from the injection well to the offset wells using the biogas as an isotopic tracer.

摘要： Embodiments of the present disclosure generally relate to processes and apparatus for carbon nanotube formation, and more specifically, to processes and apparatus for carbon nanotube alignment. In an embodiment, a process for aligning carbon nanotubes is provided. The process includes introducing an aqueous solution to a pressure-controlled system that includes a silanated glass element, a porous membrane, and a container. The process further includes applying a pressure differential across the porous membrane to draw the aqueous solution from the silanated glass element, through the porous membrane, and to the container at a flow rate to form a filtrate disposed within the container and a retentate disposed above the porous membrane, the retentate comprising carbon nanotubes. The process further includes optically detecting a position of a meniscus of the aqueous solution in the silanated glass element. Apparatus for forming and aligning carbon nanotubes are also disclosed.

摘要： Embodiments of the present disclosure generally relate to apparatus and methods for foam generation, and to apparatus and methods for evaluation of foam systems. In an embodiment, a method of analyzing foam properties includes delivering a foaming composition and a gas to a housing at a pressure of 500 psi to 6,000 psi and a temperature of 35° C. to 150° C., the housing containing an unconsolidated porous media. The method further includes flowing the foaming composition and the gas through the housing, and forming a foam by an interaction of the foaming composition, the gas, and the unconsolidated porous media. The method further includes directing the foam from the housing to a visualization chamber, the visualization chamber in fluid communication with the housing, and measuring a foam characteristic via the visualization chamber. The characteristic may include foam half-life, pressure drop through the unconsolidated media, and/or apparent viscosity of the foam.

摘要： Diabetic wounds have elevated levels of cathepsin K, a protease enzyme, which degrades proteins, such as collagen, causing delayed wound healing. By targeting cathepsin K, diabetic wound healing is ameliorated. Methods and devices for treatment include intradermal injection of odanacatib at or adjacent a wound. Methods and devices for treatment include topical application of pharmacological inhibitors of cathepsin K, for example, in the form of gel, powder, or bandage. Other methods and systems include localized genetic knock out of the cathepsin K gene by topical application of a small interfering RNA (siRNA) or antisense oligonucleotide to aid in wound healing.

摘要： The invention is directed to methods for improving the recovery of oil from subterranean geological formations, such as unconventional reservoirs. The invention is also directed to methods for evaluating the efficiency of inject-soak-produce gas injection methods for oil recovery in unconventional reservoirs. In one embodiment, a method for evaluating the efficiency of oil recovery from an unconventional reservoir rock sample includes characterizing the rock sample by imaging the rock sample using a nano-CT scanner and/or scanning electron microscopy (SEM); cleaning the rock sample by flowing solvent through it; saturating the rock sample with crude oil; and establishing initial water saturation in the rock sample.
