Which books would be recommended for solvent selection?

Hi, I'm wondering which reference books would be believable? I deal with copolymer so that I sometimes need to selectively remove only one phase. It seems like that I cannot avoid to select...

How can target molecular weight of RAFT reaction depend on CTA instead of Initiator?

I've studied and read the principle of RAFT and its mechanism. By being fragmented and added, the rate of polymerization gets slow under the equilibrium between active and dormant species. But,...

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 only a half (discharge) is used in calculation of specific capacitance?

To begin with, thank for being here to answer me. My question is 1. why is only a half (discharge part in galvanostatic charge-discharge measurement) is used when we calcaulte specific...

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...

Is it possible for permittivity and permeability of a material to be able to a minus value (less than zero) ?

I'm dealing with electromagnetic wave shielding materials and have just measured its permittivity and permeability. However, values of them are sometiems minus. Can you let me know it is...
