Do you have any suggestions on how to effectively obtain a neutral graphene oxide prepared from modified Hummer's method without using base wash?

I've tried to wash them with large amounts of water for several days yet the pH doesn't even close to 5 to 6. I started to think it's impossible to get pH 7 using this method since we are using a...

Is it true that $\det(V(A))$ may be only $\pm 1$, depending on $n$, for the last symmetric tridiagonal matrix $A$?

One can try to generalize the Vandermonde determinant in the following direction: Let $A$ be any symmetric $n$-order square matrix. Consider its powers' diagonal elements $(A^k)_{ii}$ and...

You can use RF heater or microwave heater. This is fast, consumes less power and temperature is controllable.

first of all, I think it depends on the degree of sulfonation of your sPEEK and the solvent you used for casting. I'm trying putting it in the 60 C oven for 48 h and then in the vacuum oven heated to 120 C overnight (solvent:NMP, DS around 55%).
