 that you see. If you look at them in a polarizing microscope, a Maltese cross pattern can be seen. The different colors of light can be used to provide information on the spatial arrangement of the crystals.'))
 reflects off the top of the droplet and off the surface of the support underneath, one can see various colors. The colors tell you how thick the droplet is as you go across it. So, you can actually determine the shape of the droplet from the changes in the colors.'))
, a reflection optical microscope shows these step changes by color changes, similar to color changes you see in an oil slick. Each color change represents a film thickness change of about 10 nanometers, a hundred thousand times thinner than a sheet of paper.'))

, you see a similar behavior, only on a much smaller
level& ..a million times smaller! With an electron microscope, you can see the packing
of domains. Here, like logs, the domains are cylinders and you see domains along the
length of the cylinder (looking like the sides of logs) and then others that are circular which correspond to cuts across the cylinders (looking end-on-end view of the logs).'))
 is pulled between two oppositely charged electrodes. This produces thin strands of solution and, as the solvent evaporates, very thin fibers of polymer are produced. Using an electron microscope, these fibers (about a hundred thousand times finer than a human hair) can be seen.'))
. The
optical micrograph shows interference colors from groups of nanoscopic
cylindrical domains arranged parallel to each other. These bundles of
cylinders eventually bend into swirl patterns that tell us about defects in
the copolymer ordering. This information is important in the development
of nanoscopic devices that will use this material.'))
