Ceramic materials are used in nuclear, chemical and electrical power generation industries because of their ability to withstand extreme environments. However, at high temperatures, ceramics are susceptible to thermal-shock fractures caused by rapid temperature-changing events, such as cold water droplet contact with hot surfaces. In a novel interdisciplinary approach, engineers report the use of a cheap, simple, water-repelling coating to prevent thermal shock in ceramics.

Tell him a bench has wet paint on it and he'll have to touch to be sure.

They're using the term "nano" a bit loosely, IMHO. You could say that spray paint on a car with aluminum flakes for the metallic look is nanoparticles.
What do you mean? A nanoparticle [wikipedia.org] is just a particle that's between 1 and 100 nanometers in size. The delivery medium has nothing to do with it.
Aluminum flakes are bigger than 100 nanometers and Alumina [wikipedia.org] is smaller than 100 nanometers.

Okay, okay, you win, I give. I know the terms "nano", pico, femto, etc. https://en.wikipedia.org/wiki/Metric_prefix [wikipedia.org]
I see the word "nano" usually used in reference to something active, rather than a simple passive coating. I know it's colloquial, but language is ever evolving. OP was confused by the article and I just tried to help.
I know, -1 flamebait, offtopic, troll, whatever.

PS: I wish I could respond privately to the one poster. I often write in context, and others, such as yourself, have broader knowledge and understanding. In other words, when I try to explain something to someone, I try to understand and adapt to that person. But I'm learning how this works...
