In particular, the influence of the network ,crosslinking density,, swelling ratio, and chemical composition on the ability of encapsulated chondrocytes to form extracellular matrix is examined. The cartilage produced in these hydrogels will be quantified using biochemical assays that measure DNA content and the amount of sulfated glycosaminoglycans and total collagen in the extracellular matrix.

Abstract. We report a new strategy for the crosslinking of low density polyethylene (LDPE) by using a small amount of functional nanostructured hybrid agent, octavinyl polyhedral oligomeric silsesquioxane (OVPOSS), as the crosslinker, which dramatically decreases the amount of dicumyl peroxide (DCP) and thus avoids the chain scission, scorch, and ...

Finally, the crosslinking density of the hydrogels was determined by UV/Vis spectrophotometry via the measurement of the relative amount of methylene blue (RMB) bound to the hydrogels. Results from the FTIR and 1 H NMR spectra revealed that linkages within the hydrogels occurred mainly between the O–H groups of RS and the triphosphate groups of STMP.

High-,Density, Crosslinked ,Polyethylene, (XLPE) High-,density, crosslinked ,polyethylene,, or XLPE, is a thermoset resin that is specifically designed for critical applications like chemical storage. During the XLPE manufacturing process, a catalyst (peroxide) is built into the resin, which creates a free radical.
