It is now possible to routinely perform atomistic simulations at the\nmicrosecond timescale. In the present work, we exploit this for a model binary\nLennard-Jones glass to study structural relaxation at a timescale spanning up\nto 80 microseconds. It is found that at these longer time-scales, significant\nmobility and relaxation occurs, demonstrating a reproducible relaxation\ntrajectory towards a class of asymptotic structural states which are strongly\nheterogeneous. These structures are discussed both in terms of the ideal glass\nstate and a production route towards novel amorphous crystalline nano-composite\nmicro-structures with strong interface stability.\n
