In the study of fluid dynamics and transport phenomena, key quantities of interest are often
the force and torque on objects and total rate of heat/mass transfer from them …

Artificial microswimmers offer exciting opportunities for biomedical applications. The goal of
these synthetics is to swim like natural micro‐organisms through biological environments …

Microswimmers in nature often experience spatial gradients of viscosity. In this Letter we
develop theoretical results for the dynamics of active particles, biological or otherwise …

Gradients in fluid viscosity characterize microbiomes ranging from mucus layers on marine
organisms and human viscera, to biofilms. Although such environments are widely …

Hot microswimmers are self-propelled Brownian particles that exploit local heating for their
directed self-thermophoretic motion. We provide a pedagogical overview of the key physical …

In this work, we analyze the motion of an active particle, modeled as a spherical squirmer, in
linearly varying viscosity fields. In general, the presence of a particle will disturb a …

In this work, we study active particles with prescribed surface velocities in non-Newtonian
fluids. We employ the reciprocal theorem to obtain the velocity of an active spherical particle …

Interactions between a reacting particle and the surrounding fluid are complex due to the
interplay between flow dynamics, heat and mass transfer, and chemical reactions. In the …

When droplets or particles are in complex fluid-temperature-environment conditions, the
spatial variation in temperature-dependent properties affects the overall particle-laden flow …

Fully resolved simulations are used to quantify the effects of heat transfer in the absence of
buoyancy on the drag of a spatially fixed heated spherical particle at low Reynolds numbers …
