A simple, cheap, and highly effective approach to achieve large tuning range of optical transmittance through harnessing surface wrinkling–cracking patterns on polydimethylsiloxane (PDMS) films. The ...

(Nanowerk News) As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, ...

The complexities of nanoscale surface measurement are anything but nano-sized. With the advancement of nanotechnology, nanoscale surface measurement is an integral part of the development of this ever ...
