Abstract: A method for preparing nanocomposites and nanocomposite polymeric products by dispersing nanoparticles in a polymer either by melt processing or by solution processing and bringing about migration of the nanoparticles from the bulk interior to the surface of the nanocomposites so as to produce a new asymetric type of nanocomposite in which the concentration of the nanoparticles on the surface is many times higher than in the interior bulk of the nanocomposite. These surfaces impart highly enhanced properties to the nanocomposites as compared to the pristine polymer and to nanocomposites that have not undergone the migration process, including stability against aging, longer shelf life, higher hydrophobicity, higher wear resistance, higher hardness and lower friction. The new surfaces of the nanocomposite polymeric products are produced by inducing migration of the nanoparticles to the surface thereby producing a concentration gradient below the surface.

Abstract: Disclosed is a method for dynamically and losslessly adjusting bandwidth of an embedded Resilient Packet Ring (RPR) ring network, in which dynamic and lossless bandwidth adjustment for an RPR ring network embedded in a Synchronous Digital Hierarchy (SDH)/Synchronous Optical Network (SONET) can be realized through adding a Link Capacity Adjustment Scheme (LCAS) system in the SDH/SONET processing layer. When it is required to increase ring network bandwidth, the bandwidth of the link section between sites on the SDH/SONET processing layer is first increased. Then the LCAS system in the SDH/SONET processing layer is started, and the actual bandwidth of the link on the SDH/SONET processing layer is increased losslessly with the LCAS system. Finally the bandwidth of the ring network on the RPR processing layer is increased. When it is required to decrease ring network bandwidth, the bandwidth of the ring network on the RPR processing layer is first decreased.
