Interestingly, today my group and I realized that a glass screen could contain nanoparticles all inside a water fish tank-like container. We found some interesting information involving quantum dots, such as that they can emit noises when moving based on speed if connected to speakers, and they can also emit certain colors based on their sizes. A very strong optical microscope can focus in on the particles to make them visible to the naked eye. Also, because quantum dots are soluble in water (contain polar bonds), they are thinly coated in nonpolar polymers to keep them hydrophobic (we learned this today too in the engineering lab that teflon and other nonpolar substances are hydrophobic!). The dots can be controlled by the hand, causing them to move toward or around the screen, coming out of the water to reach the hand which acts as a conductor for heat (enthalpy) because quantum dots live off of kinetic energy, and because kinetic energy equals three halves the universal gas constant (8.3145) times temperature, the hand gives off this energy and causes the quantum dots to react. This is interesting because it can be used as a form of art. The quantum dots are so colorful, they are like an iris with various shades and can really help children learn to control objects with their hands, it is good for hand to eye coordination and also for developing other parts of the brain. Also, I believe that teflon is CH2F2, therefore it has two geometric isomers: Cis (polar, hydrophilic) and trans (nonpolar, hydrophobic).
