Abstract: An improved method for enriched chirality of single wall carbon nanotubes is described. Genomic DNA, particularly salmon DNA (SaDNA) is shown to sort out single wall carbon nanotubes of specific chirality by a process of solubilization (dissolving in solution) and separation (such as centrifuging), without requiring more complex processes such as anion exchange chromatography. A possible reason for enhanced chirality separation using DNA may be attributed to its lowered GC (guanine-cytosine) content.

Abstract: A gas expansion type shock absorbing safety cloth for autocycle drivers is disclosed which comprises; a shock absorbing tube; a gas regulator connected through gas conduits to the shock absorbing tube; one or more of compressed gas storage and discharge devices connected to the gas regulator; an ignition controller; a trigger device connected through an electric wire and a pull string to the said ignition controller; and a connector disposed an intermediate position of both the electric wire and the pull string in such a manner that it is separated upon applying of a pulling force exceeding a certain predetermined value.

Abstract: Thermoplastic molding compositions are provided which have enhanced resistance to melt dripping during burning. Such molding compositions are modified by the inclusion of particulates of liquid crystal polymers which have a high aspect ratio which enhance the ability of the thermoplastic polymer to resist melt dripping.

Abstract: An improved continuous hot gas surface modification process for carbon fibers is provided. The carbon fibers undergoing such processing are passed for a relatively brief residence time through a surface treatment zone to which continuously is fed nitrogen dioxide and air under conditions which have been found to produce a surprisingly effective surface modification. The resulting carbon fibers exhibit a significantly enhanced surface area and an improved ability to bond to a resinous matrix material while retaining a substantial portion of the tensile strength originally exhibited. When incorporated in a resinous matrix material, a fiber reinforced composite article of enhanced interlaminar shear strength is formed.
