    摘要: Novel magnetorheological elastomer compositions are provided. The magnetorheological elastomers (MREs) may have aligned or randomly arranged magnetizable particles in a thermoset or thermoplastic matrix. The magnetizable particles may be coated to reduce corrosion and/or improve bonding between the particle and the matrix. The magnetizable particles may be flake-shaped. The MREs may have matrices selected from the group consisting of hydrogenated nitrile rubbers, butyl rubbers, ethylene-propylene copolymers and terpolymers, ethylene-acrylic copolymers, fluorinated elastomers, silphenylene-siloxanes, silarylene-siloxanes, poly(carborane-siloxane-acetylene)s and blends thereof. The MREs may also have matrices selected from the group consisting of styrene-butadiene block copolymers, copolyesters, polyamides, polyether block amides, polyolefin-elastomers other than polyalpha olefins, chlorinated polyethylenes, ionomers, chlorosulfonated polyethylenes, blends thereof, and blends of thermoplastic polyurethane with polyvinyl chloride (PVC), polyvinylindene fluoride (PVDF), polycarbonate, or acrylonitrile butadiene styrene (ABS).

    摘要: A tunable vibration isolation device comprising a magneto-rheological elastomer (MRE), and methods of using such a device, are provided. By manipulating a magnetic field within the MRE the device's stiffness is controlled. The vibration isolator can be constructed to provide shock absorption in one, two and three dimensions. Coupling the tunable device to a sensor feedback and a control system provides fast and accurate vibration isolation and energy dissipation for shock events in a variety of applications.

    摘要: This invention relates to an improved method for making unsubstituted carborane anions and monosubstituted carborane anions of formula: (R—CBn—Hm′)− where n is an integer ranging from 5 to about 11 and m′ is an integer ranging from 5 to 16 where the relative values of n and m′ depend upon the exact structure of the carborane and the presence of a non-hydrogen substituent. m as used herein is an integer ranging from 5 to 16. When R is hydrogen the anion is unsubstituted. When R is a halogen, a phenyl, a substituted phenyl group, such as fluorophenyl group, or any other substituent, the carborane is substituted. The method is particularly useful for preparation of twelve-vertex carborane anions R—CB11H11−, where R is a defined above, and is specifically useful for preparation of the unsubstituted carborane CB11H12-??, where R is H.
