Abstract: A nanofiber is formed by combining one or more natural or synthetic polymeric materials and one or more than one cross-linking agents having at least two latent reactive activatable groups. The latent reactive activatable nanofiber may be used to modify the surface of a substrate by activating at least one of the latent reactive activatable groups to bond the nanofiber to the surface by the formation of a covalent bond between the surface of the substrate and the latent reactive activatable group. Some of the remaining latent reactive activatable group(s) are left accessible on the surface of the substrate, and may be used for further surface modification of the substrate. Biologically active materials may be immobilized on the nanofiber modified surface by reacting with the latent reactive groups that are accessible on the surface of the substrate.

Abstract: The invention describes novel crosslinking compounds that include photoactivatable moieties. Several families of compounds are disclosed that can include one or more hydrophilic moieties that help to solubilize the compounds in aqueous environments.

Abstract: The invention provides compositions that include crosslinking agents having multiple photoactivatable groups, such as diaryl ketones, or a diaryl ketone, such as benzophenone, and at least one polymerizable monomer, such as a zwitterionic monomer. The compositions are useful as surface coating agents that provide brush type polymeric coatings. These polymeric coatings can be used on medical devices, such as artificial joints, to reduce wear and tear between the components of the joint and thus reduce or eliminate debris generated by friction between the joint components.

Abstract: Polymeric matrices including microparticles that provide sustained release of a hydrophilic bioactive agent are described. The matrices can be in the form of a coating on the surface of an implantable medical article or an in situ formed matrix. The microparticles of the matrix include a first polymer and a second polymer that modulates release of the hydrophilic bioactive agent from the matrix.

The electrical connections are obtained by means of laser (8) transmission welding (S1) or electric resistance welding.

Abstract: A stimuli responsive nanofiber that includes a stimuli responsive polymer, such as a thermally responsive polymer, and a cross-linking agent having at least two latent reactive activatable groups. The nanofiber may also include a biologically active material or a functional polymer. The stimuli responsive nanofiber can be used to modify the surface of a substrate. When the nanofiber includes a thermally responsive polymer, the physical properties of the surface can be controlled by controlling the temperature of the system, thus controlling the ability of the surface to bind to a biologically active material of interest.

Abstract: A resin-and-fiber includes a base layer and a molded layer integrally bonding the base layer. The base layer includes a fiber layer made of fiber woven fabric and a resin layer made of transparent or translucent resin. The fiber layer has a first surface and an opposite second surface. The resin layer bonds the first surface and penetrating into the fiber layer. The molded layer is made of resin and integrally bonding the second surface of the fiber layer. A method for making the present resin-and-fiber composite is also provided.

Abstract: The invention describes novel coating agents that include a polymer, one or more latent reactive groups and one or more noncovalent linking groups, the noncovalent linking groups selected to interact with a substrate to which the coating agent is applied. The coating agents are useful for providing a coating that can be further functionalized (for example, by application of additional coating layers), or for providing desirable properties to a surface.

Abstract: A method that determines the system impact of single event upset (SEU) and a single event upset (SEU) wrapper that controls a SEU controller is disclosed. The method injects faults into a component (e.g. FPGA, ASIC) of an operational system that is carrying live traffic and monitors the system's response to the faults to determine the impact of SEU on the system. The SEU wrapper sends the SEU controller a pattern scheme that includes information indicating when, where, how often, and/or how long to inject bursts of one or more faults into memory of the component of the system. A burst of faults contains faults that are consecutively injected into the array of memory blocks. After each fault in a burst is injected, one or more errors in one or more memory elements are detected and/or corrected. Information regarding the detection and/or the correction of an error is updated using registers that store counters. After injecting a burst of faults, the SEU controller waits for a predetermined amount of time.
