Molecular dynamics simulations at constant (N,V,T) are used to study the mutual effects of gold nanoparticles on the structure and dynamics of Kob–Andersen binary Lennard-Jones (BLJ) liquid within the framework of mode coupling theory of dynamic glass transition in the reciprocal space.
The results show the ‘softening’ effect of the gold nanoparticles on the liquid dynamics in terms of (i) reducing the mode coupling crossover temperature View the MathML source with respect to that of the bulk BLJ (i.e. BLJ without nanoparticles), (ii) decreasing the time interval of β-relaxation, and (iii) decreasing the exponent γ characterizing the power-law behavior of the α-relaxation time.
