Photography, First Place -- Save our Earth, Let's Go Green (IMAGE)
Caption
Tiny plastic fibers, each with a diameter of 250 nm, spontaneously wrapped around a plastic ball when they were immersed in an evaporating liquid. First reported in Science (Pokroy et al., Science 2009), the finding demonstrates a new way of controlling the self-assembly of polymer hairs. The image was produced with a scanning electronic microscope and was digitally enhanced for color.
