    Abstract: This invention relates to a process for carrying out an anionically or cationically catalytically accelerated gas phase reaction and particularly relates to a process for carrying out a catalytically accelerated gas phase polymerization reaction. The process involves the step of introducing a catalyst ion into a gaseous reaction mixture as a free anion or cation without a corresponding counterion and substantially solvent free. The catalyst of this invention can, for example, be a Ziegler-Natta catalyst or a metallocene catalyst. The gas phase reaction that is catalyzed can, for example, be a metathesis reaction, a metathesis ring-opening polymerization reaction, or a gas phase polymerization.

    Abstract: An apparatus for the production of elongated carbonaceous article includes a chamber having at least one heating element, a catalyst and a device for generating a magnetic field in proximity to or around the catalyst. In operation, a carbon-containing precursor is introduced to the chamber to contact the catalyst with a sufficient amount of heat to cause the deposition of carbon on the catalyst. Continual deposition of carbon over time forms elongated carbon structures, such as carbon fibers and carbon nanotubes. By operating the device to magnetically confine the catalyst during the formation of the carbon structures, migration of catalyst is reduced or prevented thereby minimizing contaminants in the produced products and improving the useful life of the catalyst.

    Abstract: A specimen of molecules containing the desired element is contained in a low-pressure environment and is exposed to a beam of electrons of predetermined energy, causing the electrons to be captured by the molecules. The reaction is chosen so that there is a natural dissociation into an ion containing the desired element. The reaction region is subjected to an electrical field that accelerates the ions and removes them from the reaction region, at which time the ions are exposed to a laser beam of a wavelength sufficient to photodetach a substantial number of electrons from the ions, producing neutral atoms of the desired element. The entire particle stream exiting the interaction region is subjected to a magnetic field that bends the charged ions away from the neutral atoms so that the neutral atoms can then be directed to a test specimen or collection device, as the case may be. The apparatus for carrying out the method includes a pressure vessel for maintaining the environment in which the reactions take place at a pressure in the neighborhood of 10.sup.-4 Torr and, typically, the same magnetic field that is used to separate the ions from the neutral atoms is also used to collimate the electron beam for better localization, to interact with the molecules.

    Abstract: A microelectrode for electroporating an individual cell or embryo that includes a substrate with an electrically insulated surface, a first electrode adjacent to the electrically insulated surface of the substrate, a second electrode adjacent to the electrically insulated surface of the substrate and separated from the first electrode a predetermined distance so as to form a channel, and a liquid medium situated within the channel. The liquid medium is capable of fluidic transport of the cell or embryo through or into the channel and capable of supporting an electric field. The first and second electrodes include surfaces substantially orthogonal to the electrically insulated surface of the substrate with an edge length that is less than or equal to a diameter of the cell or embryo. The predetermined distance may be 50% to 200% of the diameter of the cell or embryo.
