Erratum: Effect of a chelating agent at different pH on the spectroscopic and structural properties of microwave derived hydroxyapatite nanoparticles: a bone mimetic material (New J. Chem. (2016) 40 (5432–5441) DOI: 10.1039/C5NJ03322E)

Abstract

The authors regret their oversight in omitting to attribute Fig. 6 in this paper to its original source, a previous publication by the authors in Ceramics International, cited as ref. 30 in the original article. Prior to publication, the authors had sought permission to reproduce the images in Fig. 6. They regret not including an appropriate attribution statement in the figure caption. There is also an error in the reported pH values in the original article. Any values stated at pH 13 in the paper should be changed to pH 14. The corrected caption for Fig. 6 is shown below: Fig. 6 SEM images of the HAp precursor powder at pH 9 (a), HAp powder at pH 14 and using EDTA (b), and the HAp powders obtained upon calcination at (c) 600 1C and (d) 900 1C using precursor powder (a). Reproduced from Vijay K. Mishra et al., Ceramics International, 2014, 40, 11319–11328, with permission from Elsevier. The sentence in Section 3.2.2 ‘‘Sample (a) and (b) were...’’ on page 5437 should be changed to ‘‘Sample (a) was the HAp precursor powder prepared using EDTA at pH 9. Sample (b) was the HAp powder at pH 14 and using EDTA.’’ In addition, the authors regret unattributed text overlap with ref. 30 in Section 3.2.3. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers. © 2022 The Royal Society of Chemistry.
