I remember vividly the first experiment my science teacher demonstrated to us during my primary school. She put two electrodes into a salt solution and passed an electric current.
I hope you find time to read The Body Electric by Becker. It is very complicated, but if you have enough knowledge to understand it you will really enjoy it.
I have no advice. You write so well, I think I need to take advice from you instead of giving advice.
If you want to improve this further, find a place to refer to some recent research studies about your particular topics of interest in chem. Know what I mean? You already do a great job, so the thing to do now is show that you read professional journal articles written by people doing the kind of work you want to do.
Other than that, I have no suggestions!
