Following publication of the original article [1], the authors identified the following errors in Figs. 3, 5, and 7:
XRD pattern of different amount of trisodium citrate synthesized sample. a 0 mmol. b 2 mmol. c 3 mmol. d 4 mmol. e 6 mmol. f 8 mmol
XRD pattern of different amount of urea synthesized sample. a 6 mmol. b 8 mmol. c 10 mmol. d 15 mmol
XRD pattern of different amount of PAM synthesized sample. a 0.1 g. b 0.2 g. c 0.3 g
In Fig. 5, the XDR patterns shown in ‘a’ and ‘b’ were identical. In addition, the XDR patterns in ‘a’ and ‘b’ were the same as the XDR pattern of ‘d’ in Fig. 3.
In Fig. 7, the XDR patterns shown in ‘a’ and ‘c’ were identical.
The figures have since been corrected in the published article and the corrected figures may be found in this erratum for reference. The authors thank you for reading this erratum and apologize for any inconvenience caused.
