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...

Can you let me know the relationship b/w crystallinity and shift in XRD, Raman, FT-IR and others?

First, really thank you for reading my question. Like I said, I really wonder what kind of relationships b/w shift and crystallinity of some substances in those intruments. Please, answer me if...

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...

Can you let me know how to calculate wave impedence?

I added the equation about it here.I'm stopped since I failed to calculate wave impedence.Especially, relative permittivity and relative permeability are big obstacles for me to solve.What I'd...

Could anyone tell me what is the range of submillimeter wave?

There is confusion regarding the submillimeter-wave range. Many papers specify its range from 300GHz but some also consider its range from 100GHz. If I design an antenna on 122ghz what would I...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
