All papers published in this volume of IOP Conference Series: Materials Science and Engineering have been peer reviewed through processes administered by the Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing. • Type of peer review: Double-blind review First of all, the editor Iris will take a simple check to know whether the paper topics are included in the call-for-paper areas of this conference, if not, the submission will be rejected or seggested to other conferences. The included submissions will then be numbered and sent to the conference committee members(reviewers) for peer-review, the author names, emails and affiliations were removed constantly in this porocess.
