Simple and inexpensive, their optical method allows rapid thickness and elasticity assessments. Narayanan Menon and colleagues began their investigation by spinning molten plastic blobs into thin sheets. X-ray reflectivity analysis showed that the sheets ranged from 31 to 233 nm in thickness. Wrinkles emanating from a drop of water placed on a raft of thin plastic sheeting can do...Read full article
