What kind of solvents would be promising if I want to selectively dissolve PS out of PS-PMMA??

Hi, I wonder a specific solvent that can dissolve only PS out of PS-PMMA. Of course, solubility depends on molecular weight of polymer, but if it can be excluded for an ideal situation, I take...

Why are Fe3O4 particles differently affected by cyclic voltammetry and galvanostic charge discharge cycles?

Firstly, thank you for openning my question. These days, I'm measuring capacitive behavior of Fe3O4 and Fe3O4-modified electrolytes. As people say, metal oxides are senstive to bulk expansion...
