Development of Channeled Nanofibrous Scaffolds for Oriented Tissue Engineering

A tissue‐engineering scaffold resembling the structure of the natural extracellular matrix can often facilitate tissue regeneration. Nerve and tendon are oriented micro‐scale tissue bundles. In this study, a method combining injection molding and thermally induced phase separation techniques is developed to create single‐ and multiple‐channeled nanofibrous poly( L ‐lactic acid) scaffolds. The overall shape, the number and spatial arrangement of channels, the channel wall matrix architecture, the porosity and mechanical properties of the scaffolds are all tunable. The porous NF channel wall matrix provides an excellent microenvironment for protein adsorption and the attachment of PC12 neuronal cells and tendon fibroblast cells, showing potential for neural and tendon tissue regeneration.

Diurnal Variations of Surface Fluxes and Boundary Layer over Tibetan Plateau (Session 3: In-site Flux Observation studies)

During the GAME-Tibet IOP, surface eddy fluxes were directly measured at four stations as well as radiation fluxes. These flux data were summarized and compared in the diurnal and seasonal basis. Another important issue is the interaction between the surface fluxes and the atmospheric boundary layer. It is clearly observed in sensible heat flux and mixed layer development, and mixed layer during the daytime leads to large amplitude of diurnal variation in surface wind speed
