description:
	One day (3 shifts) are requested to perform USAXS in optimal smeared geometry of three systems: carbon black in PMMA, carbon nanotubes in PMMA and poly-caprolactone (PCL) artificial tissue scaffolds.  The PMMA/CB system has been observed to become conductive at exceptionally low loading (0.133% by volume) of carbon black.  We will measure samples with CB loading from 0.1% - 15% to follow the microstructures responsible for the electrical properties.  In the carbon tubes in PMMA system, we need to determine the diameter distribution. The nanotubes are homogeneously distributed and are present at very low loadings (0.5 % by volume).  Finally, for the PCL scaffolds, we need to determine the morphology of the scaffold surface as this is expected to correlate to our ability to grow osteoblasts in the pores.
