The authors regret that there were a few errors in the originally published article. The below listed are the clarifications. First, Figs. 3 and 4 of the publication are reproductions of Figs. 3 and 1 respectively from Anikeenko et al., J. Non-Cryst. Solids 353 (2007) 3545–3549, which should have been referenced in our paper. Secondly, Fig. 5 was inadvertently reproduced from J. Non Cryst Solids, 359, 2013, 51 – 55. It should be replaced by the following figure for the compositional parameters mentioned in the figure text. The figure is an example to show the intersection of the tangents to compute the average Tg for the compositional parameters mentioned in the text and picture.[Figure presented] Fig. 5: A Typical variation of the diffusion coefficient with temperature. The transition region is circled. The detailed equation of the tangents is given. From the intersection of these tangents exact determination of Tg is done. The two cells considered for the computation have the following parameters computed via the weighted average radii of the atomic combination considered: Cell1: Peripheral Radius: 128 pm, Central Radius: 128 pm. Cell 2: Peripheral radius: 149.5 pm, Central Radius: 124 pm >. The authors would like to apologise for any inconvenience caused. © 2013 Elsevier B.V.
