OK, I'll bite. What particular parts of the paper are you having trouble understanding? Crystal growth and nucleation? The polarized domains? Need a refresher on integrals? What do you know about the basics of this subject, and why do you need to know more and why did you download this journal article to find out?
We're not here to do all your work for you. That would simply take too much time, delivered a posting at a time, back and forth. And yes, dropping a journal article and asking for a summary is the same as asking us to do all the work for you, the lack of grade-able questions notwithstanding.
Why don't you summarize, as much as you can, of this journal article for us. That we, we can at least know how much we don't have to explain to you.
