The work describes the statistical characterization of the tensile properties of raw and treated jute yarn fibers. The yarns are treated with various alkaline sodium hydroxide concentrations (0.5, 2 and 5%) and different immersion times at room temperature (30min, 2, 8 and 12h). Due to the scattering of the experimental results, statistical analysis was performed using both two- and three-parameters...
The effect of thickness and alkoxy side chains on the optical properties of poly(p-phenyleneethynylene)-alt-poly(p-phenylenevinylene)s (PPE–PPVs) have been investigated in parallel fashion. A Forster energy transfer mechanism has been invoked in order to infer the exciton diffusion length (LD). The latter parameter has been determined for six differently alkoxy-substituted PPE-PPVs for different thicknesses...
