This study focuses on the effect of twist and porosity electrical conductivity carbon nanofiber (CNF) yarns. The process fabrication CNF yarns included synthesis aligned ribbons polyacrylonitrile (PAN) nanofibers via electrospinning. PAN were twisted into with levels ranging from zero to high twists 1300 turn per meter (tpm). imposed substantially improved interactions between reduced porosity. subsequently stabilized in air, then carbonized nitrogen at 1100 °C for 1 h. Compressive stresses...
In this manuscript, we discuss relationships between morphology and mechanical strength of carbonized structures, obtained via pyrolysis polymeric precursors, across multiple length scales, from carbon fibers (CFs) with diameters 5-10 µm to submicron thick nanofibers (CNFs). Our research points radial inhomogeneity, skin-core structure, as a size-dependent feature polyacrylonitrile-based CFs. This inhomogeneity is surface effect, caused by suppressed diffusion oxygen stabilization byproducts...
We studies the surface characteristics and mechanical properties of four brands poly(ether urethane) feeding tubes incubated for eight weeks at 37/spl deg/C in simulated gastric juice. Surface degradation was characterized by scanning electron microscopy energy dispersive spectroscopy (SEM/EDS). Changes were monitored with an Instron tester. All found to contain X-ray opaque filler (BaSO/sub 4/ or Bi/sub 2/S/sub 3/). Incubation juice caused some three brands. This demonstrated presence small...
