Transformation from a network to a close-packed structure in the structural models of CaO-SiO 2 binary glasses" Vol.133, No. 9, p. 481-487The cover image illustrates the evolution of oxygen close packing in structural models xCaO-(100 -x)SiO 2 with varying CaO content (x 0, 30, 60, 90).The Reduced Atomic Arrangement (RAA) method was employed to visualize and quantify the transformation from a continuous tetrahedral network to a pseudo-close-packed "hyperordered" structure within disordered systems.These findings offer a new perspective on structural motifs in oxide glasses and provide insights into the limits of glass formation.
