Nanoscale: how salt cubes look fancy in a scanning electron microscope


Some things, like atoms and molecules are way too tiny to look at them using regular optical microscopes. This is where the scanning electron microscope comes into place. It sees the charges of the atoms and then is able to create a map of those charges. The map that results is a representation of those atoms.

Since salt is a crystal, you can see a whole lot of salt cubes in the nanoworld. Fancy a cube? A salt cube? The scanning electron microscope uses beams of electrons to see things up to 1 nm small, which lets you see even individual atoms. Yep, nothing is the same when you zoom in like crazy on them.

Superhydrophobic coating brings nanotech in our houses [technology]

NeverWet is a superhydrophobic nanotech coating created by Ross Technology Corp that repels any kind of wet material from the surfaces it has been applied on. More than that, if you cover an iPhone in this coating and put it in a water tank the phone will simply work unhindered.

[UPDATE: 30 November 2011]NeverWet will be available from mid 2012. Details here.
[UPDATE: 25 June 2013]Neverwet is finally here. Click for details.

Well, that is a thing I REALLY want to have in my house. Can you imagine clothing that never needs washing, tables that can be cleaned pretty easy and electronics that can be used even in water? That time has come. I am curious to know how much this thing costs and when will we be able to have it. Thanks Gizmodo for sharing.
