dear editor,<br /><br />just now I looked at your edited document and have a question.<br /><br />You edited sentence, "The elemental compositions these materials were identical to those from industrial TiO<sub><span style="font-size: small;">2</span></sub>, although the peak intensity varied." doesn't make sense. <br /><br />There are two subjects ("the elemental compositions", and "these materials")&nbsp;and only one verb.<br /><br />What I tried to write initially was as follows.<br />"The elemental compositions from TiO2 products-extracted materials were identical to those from industrial type of TiO2, although the peak intensity was variable."<br /><br />please edit it again and let me know soon since I must submit the document SOON.<br /><br /><br />
