Abstract: Supported amine polymer adsorbents based on polymers containing only or primarily primary amines sites are to be used as regenerable adsorbents for CO2 capture from ultra-dilute gas streams, such as ambient air, or from mixtures of gases containing preferably at least I 0% oxygen. and can also be useful for use at the moderate gas pressures found in typical post-combustion capture processes, such as flue gas from large point sources such as coal-fired power plants. Preferred supported solid amine adsorbents of this invention are based on poly(allylamine) (“PAA”) and poly(vinyl amine) (“PVAm”), both of which are linear polymers, and their derivatives, containing substantially all primary amine groups, supported on substrates. Preferred such substrates include silica mesocellular foam (MCF) and mesoporous-.gamma.-alumina, as well on mesoporous-.gamma.-alumina coated throughout the pores of MCF, most preferably of monolithic structure.

Abstract: An endoluminal pursestring device is provided and includes a handle assembly, a shaft, an elongated fork, a plurality of surgical fasteners disposed with the shaft, and a suture engaged with the surgical fasteners. The suture is secured to a head of each of the surgical fasteners, and extends proximally through the handle assembly. In use, a distal end of the endoluminal pursestring device is positioned adjacent tissue surrounding a lumen, and the handle assembly is rotated to cause the distal-most surgical fastener to be rotated into the tissue. The following surgical fasteners are also rotated into other portions of the tissue surrounding a lumen. The suture connecting each of the surgical fasteners is then pulled such that the surgical fasteners are pulled together, thereby closing the lumen.

Abstract: An apparatus for joining two hollow organ sections includes a staple cartridge assembly including an annular wall, an anvil assembly, a buttress member, and a fastening member. The annular wall of the staple cartridge assembly defines an inner aperture in an inner surface thereof and an outer aperture in an outer surface thereof. The buttress member is configured to be positioned on a distal surface of the staple cartridge assembly. The buttress member defines a cutout on a peripheral portion thereof. The fastening member has a first end securely affixed to the inner aperture of the annular wall of the staple cartridge assembly and a second end securely affixed to the outer aperture of the annular wall of the staple cartridge assembly to secure the buttress member on the staple cartridge assembly. The cutout of the buttress member is in registration with the outer aperture of the annular wall.

Abstract: Methods of extracting a hydrocarbon-based product from subsurface (oil) shale formations are provided. These methods rely on the use of an extraction fluid comprising pentane for facilitating the production of a mobile hydrocarbon-based product when the pentane contacts hydrocarbons in subsurface shale. The contacting process, and the subsequent process of recovering the mobile hydrocarbon-based product, is further enhanced by the methods of fracturing and/or rubblizing portions of the shale formation, so as to enhance their fluid permeability.

Abstract: A ferrihydrite catalyst composition can comprise a ferrihydrite of a structural promoter metal, a chemical promoter metal and potassium to form an amorphous nanoparticulate. The ferrihydrite catalyst can be formed by dissolving an iron salt, a structural promoter metal salt and a chemical promoter metal salt in water to form an aqueous iron solution. A ferrihydrite solid can be precipitated from the aqueous iron solution by addition of a precipitating agent under conditions such that the ferrihydrite solid is a nanoparticulate. A potassium can be incorporated into the ferrihydrite solid to form a ferrihydrite catalyst precursor. The ferrihydrite catalyst precursor can be calcined to form the ferrihydrite catalyst. A synthesis gas can be readily converted to a fuel product by contacting the ferrihydrite catalyst with the synthesis gas under reaction conditions sufficient to form a fuel product mixture.
