Query: Cooling-Rate Effects in Sodium Silicate Glasses: Bridging the Gap
  between Molecular Dynamics Simulations and Experiments   Although molecular dynamics (MD) simulations are commonly used to predict the
structure and properties of glasses, they are intrinsically limited to short
time scales, necessitating the use of fast cooling rates. It is therefore
challenging to compare results from MD simulations to experimental results for
glasses cooled on typical laboratory time scales. Based on MD simulations of a
sodium silicate glass with varying cooling rate (from 0.01 to 100 K/ps), here
we show that thermal history primarily affects the medium-range order
structure, while the short-range order is largely unaffected over the range of
cooling rates simulated. This results in a decoupling between the enthalpy and
volume relaxation functions, where the enthalpy quickly plateaus as the cooling
rate decreases, whereas density exhibits a slower relaxation. Finally, we
demonstrate that the outcomes of MD simulations can be meaningfully compared to
experimental values if properly extrapolated to slower cooling rates.
