abstract = {Binary liquid mixtures can exhibit nanosegregation, albeit
being fully miscible and homogeneous at the macroscopic
scale. This tendency can be amplified by geometrical
nanoconfinement, leading to remarkable properties. This work
investigates the molecular dynamics of tert-butanol
(TBA)–toluene (TOL) mixtures confined in silica
nanochannels by quasielastic neutron scattering and
molecular dynamics simulation. It reveals a decoupling of
the molecular motion of each constituent of the binary
liquid, which can be followed independently by selective
isotopic H/D labeling. We argue that this behavior is the
signature of spatially segregated dynamic heterogeneities,
which are due to the recently established core–shell
nanophase separation induced by mesoporous confinement.},
