Glass fragility is a byproduct of early attempts to apply law of corresponding states scaling to the temperature dependent thickening of glass forming liquids. Efforts to plot the logarithm of the viscosity vs. inverse temperature scaled to the glass

In a simple time of flight experiment, the speed of sound is observed to travel about 5% slower inside a corrugated irrigation pipe as compared with measurements conducted in open air. Although some theoretical understanding for this retardation is p

The compositional variation of the fragility of alkali silicate glasses is shown to mimic that of most all other network forming oxide glasses when graphed as a function of a coarse-grained network connectivity which incorporates rigid structural uni

Simple glucose solutions were heat treated in an attempt to produce carbon nanodots (CNDTs) with a monodisperse size distribution using a bottom-up approach. Absorption and fluorescence properties of the heat-treated solutions display remarkable simi

In their Comment, Wilkinson and Mauro (WM) raise the issue that our coarse-graining interpretation of the fragility in network forming glasses lacks the first derivative quality inherent in their temperature-dependent constraint theory (TDCT). In res

The general physics course that is taught in most departments as a service course for pre-med or pre-health students is undergoing a large shift in course content to better appeal to this group of learners. This revision also extends to the laborator

Classical considerations of the stability of amorphous networks have sensibly concluded that a network should weaken when mechanical constraints are removed. In covalently-bonded glass networks, this weakening is evidenced by the “fragility” and,
