Maybe I the core is indestructible, so maybe when Pixals body was destroyed Chen kept the half-core at his island and it may still be there.

Also, going back to Zane being made only as a way for Julien to live forever, I don't really think this is true. If Zane's human-like personality is due to Julien's soul being in him, Zane wouldn't be Zane, he would act like Julien. And also we don't see much of the Dr. but from what we do see, we can infer the he genuinely loves Zane. Maybe he found a way to give him a piece of his soul in order to make him more like a son, and to make him more human; but I don't think he would use Zane for his own selfish needs.
