Notice here that each chemical presented here has a property that we use as a society. Here is a video that describes a material science breakthrough that will be utilized by the military. Its properties are that it is stronger and lighter than traditional metal armor, heat doesn't travel through the material as fast (heat insulator). What are some other properties that can be used by society and are there other applications we can use this material for?
