Inspired by natural mobile microorganisms, researchers have developed micro/nanomotors
(MNMs) that can autonomously move by transducing different kinds of energies into kinetic …

Elasticity typically refers to a material's ability to store energy, whereas viscosity refers to a
material's tendency to dissipate it. In this review, we discuss fluids and solids for which this is …

In active matter systems, individual constituents convert energy into non-conservative forces
or motion at the microscale, leading to morphological features and transport properties that …

Mobile microrobots, which can navigate, sense, and interact with their environment, could
potentially revolutionize biomedicine and environmental remediation. Many self-organizing …

Out of equilibrium, a lack of reciprocity is the rule rather than the exception. Non-reciprocity
occurs, for instance, in active matter,,,,–, non-equilibrium systems,–, networks of neurons …

Progress in optical manipulation has stimulated remarkable advances in a wide range of
fields, including materials science, robotics, medical engineering, and nanotechnology. This …

Swarms, which stem from collective behaviors among individual elements, are commonly
seen in nature. Since two decades ago, scientists have been attempting to understand the …

Active matter, which ranges from molecular motors to groups of animals, exists at different
length scales and timescales, and various computational models have been proposed to …

Phase segregation is ubiquitously observed in immiscible mixtures, such as oil and water, in
which the mixing entropy is overcome by the segregation enthalpy,–. In monodispersed …

Pair interactions between active particles need not follow Newton's third law. In this work, we
propose a continuum model of pattern formation due to nonreciprocal interaction between …
