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 …

Over the past 15 years, the field of microrobotics has exploded with many research groups
from around the globe contributing to numerous innovations that have led to exciting new …

Swimming microrobots that are energized by external magnetic fields exhibit a variety of
intriguing collective behaviors, ranging from dynamic self-organization to coherent motion; …

Untethered micro/nanorobots have been widely investigated owing to their potential in
performing various tasks in different environments. The significant progress in this emerging …

In simple fluids, such as water, invariance under parity and time-reversal symmetry imposes
that the rotation of constituent 'atoms' is determined by the flow and that viscous stresses …

Active materials are characterized by continuous injection of energy at the microscopic level
and typically cannot be adequately described by equilibrium thermodynamics. Here we …

Fluids in which both time reversal and parity are broken can display a dissipationless
viscosity that is odd under each of these symmetries. Here, we show how this odd viscosity …

Higher-order interactions shape collective dynamics, but how they affect transitions between
different states in swarmalator systems is yet to be determined. To that effect, we here study …

Micrometre-sized colloidal particles can be viewed as large atoms with tailorable size,
shape and interactions. These building blocks can assemble into extremely rich structures …

Here, recent significant developments are reviewed in manipulating soft matter systems
through the use of magnetic torque. Magnetic torque enables the orientation, assembly, and …
