I realized human beings have been using nano-particles for a very long time. The Lycurgus Cup, probably made in Rome in 4th century AD, exhibited different colors under different conditions. Known as dichroic, the glass contains nano-sized gold and silver that display red and green when light passes from different direction, respectively.

Another amazing feature of nano-particles is the self-organization and self-assembly. As we acquired the technology to manipulate nano-particles and concluded the quantum laws of it. Several objects Belousov Zhabotinsky reaction. It is an classical example of non-equilibrium thermodynamics, and displays perfect harmony of motion and stability. Resulting in the Oscillating Chemical reactions, the particles are reacting with each other back and forth in a very long time, therefore creates such effect.

The Marangoni effect is another example, which is less complex but display similar feature. Due to the surface tension gradient, two fluids are transferring up and down, which creates the visual effect of "tears" of wine in the case of alcohol and water. Besides, I found a very interesting experiment using Marangoni effect that creates a soap propelled boat.

Hey Rui! I really liked this week's topic myself! I also thought it was really amazing that we've been using nanotechnology all this time without even knowing it. Before when I use to hear nanotechnology I would think tiny little robots that can come into your body and control your brain, but now I actually understand. hahaha. What I found really interesting though is that the actual laws of nature change at that size, which I didn't really think was possible. Check out my blog and let me know what you think as well!
ReplyDeleteYeah, a lot of scientists are trying to build a general physics law that explain motion in any size and any status. Maybe one day we can see it!
DeleteHello
ReplyDeleteThe picture of Belousov–Zhabotinsky reaction looks quite similar to the shrimp slice put upon Japanese Noodles.lol
Haha, Interesting Point!!
DeleteYour post is very interesting although the introduction is a little bit long. I like the way you organized the lecture and expanded into outside resources. The video gives me the most impression, which the Marangoni Effect can let small boat floated on the water and let pepper get away from the soap toothpick. Although it looks like a physics experiment, it actually related to true arts and that's how we have realized from the lecture.
