  • A material’s internal structure is known to dictate its macroscopic properties through structure-dependent particle dynamics, as exemplified by the so-called de Gennes narrowing. Through experiments and simulations on soft colloid suspensions, the authors reveal a breakdown of this correlation, showing that the q-dependent relaxation time remains unchanged across length scales and that single-particle elasticity facilitates structure-independent relaxation.

  • 2D superlattices of colloidal quantum dots are challenging to fabricate over large areas without cracks. Here, Pinna et al. demonstrate how applying lateral pressure during self-assembly of PbS quantum dots improves order and coverage, enabling large-area, crack-free films with high electron mobility.

  • Auxetic materials are characterized by a negative Poisson’s ratio - they become thicker when stretched. Here, authors reach the limit of auxetic behavior, known as hyper-auxetic, in polymer networks, hitting an unconventional mechanical critical point.

  • Amorphous glassy materials do not usually heal damage spontaneously due to their low molecular mobility. Here, the authors show via molecular dynamics simulations that oscillatory deformations of the right frequency and amplitude can accelerate glassy dynamics, promoting molecular flow and damage repair.
