Oleophobic Surfaces - Anti-Graffiti Demo is a hands on cart demonstration for spontaneous, 3-10 minute interactions with visitors. The visitors will explore several surfaces that display oleophobic properties due to material science research at the nano scale. Coatings can preserve, protect, lubricate, grip, and a myriad of other behaviors. For example, walls can be coated with material that when dry, will prevent the adhesion of paint or ink. In this demonstration, we're examining coatings that are oleophobic, "oil hating," and prevent low surface tension liquids from adhering to it.
Nanoscale science and technology (“nano” for short) is all around us and growing rapidly. Learn how you can use nanotechnology to clean drinking water right now!
"Exploring Size - Ball Sorter" is a hands-on activity in which visitors use sieves with different-sized holes, to sort balls by size. They learn that researchers are developing new technologies that can sort nano-sized things, including filters with nano-sized holes.
