Listen to part of a lecture in a material science class.
OK.Last time we finished going over some of the fundamental concepts of nanotechnology,
the multi-disciplinary science of manipulating or controlling extremely small units of matter on the scale of molecules or even atoms.
So, I want to talk about how nanotechnology is being used today.
And just to give you an idea, we’ll look at one particular application.
A team of material scientists in Massachusetts has been working on a new ultra-thin coating,
a nano coating that might be applied to objects like bathroom mirrors, car windows, and eye glasses to prevent fogging.
And the coating has the potential to be a permanent solution, unlike the kinds of anti-fogging spray-on liquids that are on the market today.
Now, fogging often occurs when a cold surface comes into contact with warm moist air, such as when a glass shower door or mirror fogs up during a warm shower.
Now, what’s actually happening is, what the fog is, is thousands of tiny spherical water droplets condensing on the surface of the glass.
Light hits the water droplets and is scattered in random directions, causing the fogging effect.
