Peer review declaration

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: Single-blind Single-blind reviewing. 117 submitted full conference papers were reviewed independently by the 30 members of the scientific committee. The six members of the local organising committee also helped with the review process. The acceptance was granted to the papers with the positive reply of two independent reviewers. The reviewers were asked to rate each manuscript with regards to the following criteria: technical, presentation, quality, and English language. The submissions with low ratings were rejected with some comments to improve for their future publication endeavours in other avenues. 10 papers were desk rejected by the conference science committee chair and co-chair due to being out of scope. In 69 instances, the submitted papers were asked to be revised and submitted for another round of reviews. The second round of the review process was conducted by the chairs of various icRS2021 committees to make sure that the comments of the original reviewers were considered by the authors. • Conference submission management system: Aventri • Number of submissions received: 117 • Number of submissions sent for review: 107 • Number of submissions accepted: 73 • Acceptance Rate (Number of Submissions Accepted / Number of Submissions Received X 100): 62% • Average number of reviews per paper: 2 • Total number of reviewers involved: 36 • Any additional info on review process: - • Contact person for queries: • Name : Pezhman Ghadimi Affiliation: University College Dublin Email : icrs2021dublin@gmail.com
