Abstract

The design of reversible adhesives requires both stickiness and the ability to remain clean from dust and other contaminants. Inspired by gecko feet, we demonstrate the self-cleaning ability of carbon nanotube-based flexible gecko tapes.

- Uniform Hierarchical Frameworks Patterned by Movable Magnetic Microparticles
  Xiaolei Wang, Hui Zhu, Yi Bao, Fan Yang, and Xiurong Yang
  ACS Nano2011 5 (4), 3250-3256
  Inspired from the ancient movable type printing, we proposed a three-dimensional tunable method for the replicable patterning of uniform patterned framework. Different sized magnetic particles were utilized as the “type-heads” for patterning. The ...
