We find that dynamical heterogeneities are present in silica for temperatures lower than 4000 K. We have also shown that string-like motion is present. We observe that oxygen and silicon atoms are heterogeneously moving in a string-like motion on different time scales.
WebAnswer (1 of 2): This is a good question indeed. To explain this one must consider charge density factor (e/p ratio) on nucleus. For Al+3 it has 13 protons and 10 electrons. That …
