The above is a question from my roommate. She asked me to ask my dad, but his doctorate is in chemical engineering and I’m too lazy to translate it into Korean.
Are there any sources she could be looking at? Journals, articles, books?
I don’t know if this quote from our IM chat will make clearer what kind of information she’s looking for:
Really, I have no idea - I’m just an English major, I just smile and nod. Hopefully you guys will be more helpful. 
Thanks in advance.
