Title of Paper : MONOCLINIC AND ORTHORHOMBIC 1 STRUCTURES OF NANOCRYSTALLINE 2 ZIRCONIA: PRELIMINARY STUDY ON 3 PREPARATION OF ZIRCONIA NANOMATERIALS 4 AS AN ADSORBENT FOR MOLYBDENUM-99 5 RADIONUCLIDE
Referee Name : Aziz K. Jahja
Comment on Descriptions 1. Title
[ ] Appropriate
[ ] Should be changed The title is too long 2. Abstract
Yes[] No[ ] Is the length reasonable?
Yes[] No[ ] Is it an appropriate summary of the content?
3. Main Text
Yes[ ] No[] Is there anything new in this work? The central issue in this work is the preparation and characterization of zirconia nanomaterials, but the authors have not adequately clarified whether this is an original work or have been carried out by other researchers before. But judging from the references cited, this work is basically a replica of previous work done by other authors.
Yes[] No[ ] Is the relation to previous studies adequately stated?
Yes[] No[ ] Are the assumption(s) and/or method(s) described comprehensively?
Yes[ ] No[] Are the new results adequately emphasized? This experiment is a duplication of experiments carried out previously by other authors, no particular emphasize of new results.

How did the authors confirm this to be 100% Baddeleyite phase? What is the Space Group, atomic positions (fractional coordinates), and the lattice parameters of this crystalline phase?

etc How is the fractional composition of the ‘’Baddeleyite’’ and the ZrO2 phase calculated ? 427 What is the Scherer method ? Could the authors show the use of this method so they came
up with this result?

What are the functional differences of a monoclinic , tetragonal and an orthorhombic nano zirconia?regarding their application as an adsorbent for Molybdenum-99 (99Mo).?
Final comments and recommendations:
- Some of the English need to be brushed up and brought up to satisfy the standard scientific English requirements.
- Some of the analysis/calculation procedures need to be elaborated and backed up by explicit calculation or graphical method, such as the ‘’Scherer’’ method and the fractional phase determination.
- Finally the reviewer would like to see a few arguments from the authors that their work is not just a replica of the work referred to in ref. [2] (Chakravarty et al) and in other references, so please clearly state the original contribution of this work.
This paper is recommended to be [ ] Accepted without further revision [ ] Accepted with minor revision [ ] Major Revision is required [ ] Rejected
