    Abstract: The present invention provides a bicomponent fiber having increased surface roughness. The fiber includes a first polymer and a composite, wherein the composite forms a layer which forms at least a portion of the fiber's surface. The composite is formed by a second polymer and a filler, where an average particle size of the filler can be greater than a thickness of the layer formed by the composite. The fibers can have a round, oval, trilobal, triangular, dog-boned, flat or hollow shape and a symmetrical or asymmetrical sheath/core or side-by-side configuration. When the fiber has a sheath/core configuration, the composite can form the sheath, and the average particle size of the filler can be greater than the thickness of the sheath.

  • Patent number: 7198878
    Abstract: The invention is a photoswitchable benzocyclobutene-based polymer that while remaining aqueous developable, avoids the problem of significant moisture uptake. The oligomer or polymer comprises a polymeric backbone, benzocyclobutene reactive groups, and photoswitchable pendant groups. The pendant groups are bonded to the polymeric backbone and are characterized by the presence of a moiety that converts to carboxylic acid upon exposure to activating wavelengths of radiation a carboxylic acid. When the oligomer or polymer is subsequently heated to cause cure of the oligomer or polymer, carbon dioxide is emitted and the group forms a substantially non-polar moiety. The invention is also a method of making such a polymer and a method of forming a patterned film using such a polymer.

  • Patent number: 7145453
    Abstract: A method for detecting a latent environmental effect (such as a corrosive environment under insulation) or a latent structural change (such as a crack in a concealed structural member) at a known remote concealed location. The method of the instant invention includes three steps. The first step is to use a harmonic electromagnetic transponder at the known remote concealed location of the latent environmental effect or the latent structural change, the harmonic electromagnetic transponder having a reactive portion which reacts to the latent environmental effect or latent structural change to modify the harmonic emission of the transponder. The second step is to remotely interrogate the transponder by directing electromagnetic radiation at the transponder. The third step is to use the harmonic emission of the transponder to remotely determine the latent environmental effect or the latent structural change.

  • Patent number: 7135282
    Abstract: The present invention relates to the expression of peptides on viral particles, and more particularly to the expression of peptides on the interior or the viral capsid. Methods are described for modifying viruses so that exogenous epitopes are expressed on the interior of the viral capsid. Viruses that can be modified include (+) stranded RNA viruses, especially plant (+) stranded RNA viruses such as the cowpea mosaic virus. Internal expression is especially useful for the expression of hydrophobic epitopes. The modified viral particles also find use as vaccines and as such are capable of eliciting an immune response.
