I assume that the shell in hollow core shell materials will be weak, so it is easy to break.
It depends on energy intensity of grinding equipment and mechanical properties of particles. For example, high-energy milling with steel grinding balls leads to cracking of hollow alumina microspheres (>10 micron) with shell width
We know impact factor is calculated based on citation. What formula used in it. Is it simple, number of citations divided by number of articles published or any thing else.
