(b) Scattered intensity as a function of time (at fixed shear rate) from multi-walled carbon nanotubes suspended in PIB Boger fluid. Initially flow aligned, the developing intensity in the horizontal direction reflects fractionation in tube orientation with some tubes aligned with the flow and others with the vorticity direction.

(c) Comparison of experimental (left) and theoretical light scattering predictions (right) for multi-walled carbon nanotubes. Tubes with a characteristic length of approximately 10microns can be seen in the micrograph. Note that the majority of the tubes are not straight, but rather have some degree of curvature.

Osteoblasts were cultured on a thin film of poly(L-lactic acid), fixed and stained. DAPI was used to stain cell nuclei to fluoresce blue and Texas-red-C2-maleimide was used to stain cell membranes to fluoresce red. The large “iron cross” in the background is birefringence from a spherulite seen with crossed polarizers.

Picture 1: The nanoporous surface structure is a result of evaporative cooling at the fiber surface due to rapid solvent evaporation. The cooling results in vapor condensation from moisture in the atmosphere in the form of droplets that imprint the surface of the fiber.

Hi resolution TEM (transmission electron microscopy) of nano hydroxyapatite (HA) prepared by a spray drying method. TEM shows that HA particles, 5 nanometer to 10 nanometer in size, have well defined crystalline structure.

This image is a small-angle neutron scattering pattern measured for a dilute aqueous suspension of single-walled carbon nanotubes (SWNTs) under simple shear flow. The shear rate is 2000 1/s and the measurements are taken in the plane of flow and vorticity. As predicted by theory for this aspect ratio and composition, the patterns exhibit little anisotropy, consistent with only weak alignment.
