Active fluids exhibit spontaneous flows with complex spatiotemporal structure, which have
been observed in bacterial suspensions, sperm cells, cytoskeletal suspensions, self …

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 …

Viscoelastic fluids are a common subclass of rheologically complex materials that are
encountered in diverse fields from biology to polymer processing. Often the flows of …

The concept of “single‐atom catalysis” is first proposed by Tao Zhang, Jun Li, and **gyue
Liu in 2011. Single‐atom catalysts (SACs) have a very high catalytic activity and greatly …

Liquid crystals (LCs) are ubiquitous in display technologies. The orientational ordering in the
nematic phase of LCs gives rise to structural anisotropy, the ability to form topological …

The dielectric tensor is a physical descriptor of fundamental light–matter interactions,
characterizing anisotropic materials with principal refractive indices and optic axes. Despite …

Humankind has been obsessed with knots in religion, culture and daily life for millennia,
while physicists like Gauss, Kelvin and Maxwell already involved them in models centuries …

Active matter agents consume internal energy or extract energy from the environment for
locomotion and force generation. Already, rather generic models, such as ensembles of …

The past decade has witnessed a rapid growth in understanding of the pivotal roles of
mechanical stresses and physical forces in cell biology. As a result, an integrated view of …

The ability to control both the mobility and chemical compositions of microliter-scale
aqueous droplets is an essential prerequisite for next-generation open surface microfluidics …
