20100136741 | BRANCHED PHENYLENE-TERMINATED THIOPHENE OLIGOMERS - A composition comprising a plurality of molecules. Each of the molecules has a core comprising at least one aromatic ring and at least three pendant arms chemically bonded to the core. The pendant arms comprise a phenylene-terminated thiophene oligomer. | 06-03-2010 |
20110205685 | COMPOSITE DIELECTRIC MATERIAL FOR HIGH-ENERGY-DENSITY CAPACITORS - A composite dielectric material having a plurality of particle cores, each surrounded by polymer strands that are chemically bonded to the surface of the particle core. Each polymer strand includes a linker, through which the polymer strand is attached to the surface, an interfacial core-shielding (ICS) group bound to the linker, and a polymer molecule bound to the ICS group. The ICS groups are designed to inhibit electrical breakdown of the composite dielectric material by (i) deflecting or scattering free electrons away from the particle cores and/or (ii) capturing free electrons by being transformed into relatively stable radical anions. Representative examples of the particle core material, linker, ICS group, and polymer molecule are titanium dioxide, a phosphonate group, a halogenated aromatic ring, and a polystyrene molecule, respectively. | 08-25-2011 |
20110295029 | NANOPARTICLE DISPERSIONS WITH LOW AGGREGATION LEVELS - A composition includes an inorganic particle core and an initiator molecule chemically bonded thereto. The particle core is formed of a material having a dielectric constant of about fifteen or more. The initiator molecule includes a chain having about twenty or fewer carbon atoms and a phosphorous atom chemically bonded to an end of the chain. An alkyl derivative of an aryl moiety terminates another end of the chain. | 12-01-2011 |
20120174274 | ENHANCEMENT OF ARMOR - An apparatus comprising a multi-layered armor. The multi-layered armor includes a stack of layers, each layer including a mesh of fibers of first polymer molecules, surfaces of the fibers being functionalized by at least one of hydroxyl, ketone, and amine groups. The multilayered armor also includes second polymer molecules being hydrogen bonded to the fiber surfaces, some of the second polymer molecules having hydroxyl, ketone, amine or carboxylic acid groups.
