I would love to see a SEM (scanning electron microscope) picture of the exact area where the water comes in contact with these fibers (instead of this non-SEM fuzzy picture: http://www.wired.com/wp-content/uploads/2014/06/plume-poppy-contact-angle-mod.png http://www.wired.com/wp-content/uploads/2014/06/plume-poppy-...). They have the equipment. They should have done it!

- lokki 12y agonit-pick alert Basic SEM work requires a conductive surface (carbon coatings also work), and in some cases you can skip that if you have a good carrier gas. The real limitation here is that most SEMs require you to pump down to vacuum, which would eliminate the water. Even variable-pressure SEMs that operate close to atmosphere require a purge, first. So the limit is the vacuum, not the metal coating.
