Abstract: This disclosure concerns electrically conducting poly(pyrazoles). The concept of oligomerizing and polymerizing substituted aminopyrazole derivatives combined with a monomer activation procedure involving base-mediated conversion of the protonated pyrazole ring nitrogen to amine salt was developed. This disclosure concerns the specific chemistries needed for the synthesis of a pyrazole monomer used in the polymer synthesis. The procedure used for blending the novel polypyrazoles with other compounds needed for construction of solar cells for testing was developed. This disclosure concerns the concept of using these types of heteroatom-rich, electron-deficient oligomers or polymers as n-dopable or p-dopable electron acceptors in photovoltaic cells. This disclosure concerns synthesizing the starting monomer compounds and polypyrazoles.

Abstract: Methods and systems for limiting the sudden expansion of propellant gasses, products of combustion when firing a gun, exiting a barrel of a gun, which otherwise would result in a very loud noise, sharp “recoil” of the gun, and a pronounced “muzzle flash” if released unrestricted. By utilizing two or more completely segregated, or partially segregated, expansion chambers, the gasses can be allowed to sequentially expand and cool under tightly controlled conditions governed by the size and location of holes, or passageways, in the barrel which communicate with the interior of the expansion tube that encompasses the barrel. The expanding gasses are further controlled by the locations and volumes of each segregated expansion chamber, and holes in the structural vertical and horizontal bulkheads of the expansion tube, which can “steer” the gasses in order to achieve easy expansion as well as gas flow disruption goals by design.

Abstract: A package including at least one absorbent article and packaging. The packaging includes a flexible pocket having a hollow interior, an opening extending into the interior, a flap for covering the opening, and an adhesive closure positioned on the flap for releasably holding the flap in the closed position. The closure is spaced from a distal edge of the flap to permit a portion of the flap to be grasped and separated from the pocket without releasing the closure.

Abstract: A master package including a plurality of utility packages and removable master packaging surrounding the utility packages. Each utility package includes a plurality of absorbent articles and utility packaging including a flexible pocket and a recloseable opening.
