A current common topic of study among scientists and engineers is how to reduce energy
usage. As the loading power of engineering devices is constantly upgrading, while they are …

The fluid dynamics of microswimmers has received attention from the fields of microbiology,
microrobotics, and active matter. Microorganisms have evolved organelles termed cilia for …

Bioconvective heat and mass transport phenomena have recently been the subject of
interest in diverse fields of applications pertaining to the motion of fluids and their …

This paper proposes a review focused on exotic chemotaxis and cross-diffusion models in
complex environments. The term exotic is used to denote the dynamics of models interacting …

This paper proposes a survey and critical analysis focused on a variety of chemotaxis
models in biology, namely the classical Keller–Segel model and its subsequent …

Transport phenomena involving thermo-bioconvection have become an interesting field of
research due to their novel application in various fields of engineering, bio-energy systems …

Active particles contain internal degrees of freedom with the ability to take in and dissipate
energy and, in the process, execute systematic movement. Examples include all living …

The current work intends to describe the heat and mass transfer in the mixed bioconvective
flow of nanofluid along the sphere. This analysis also takes into account the influences of a …

Mathematical modelling of the movement of animals, micro-organisms and cells is of great
relevance in the fields of biology, ecology and medicine. Movement models can take many …

We investigate a new form of collective dynamics displayed by Thiovulum majus, one of the
fastest-swimming bacteria known. Cells spontaneously organize on a surface into a visually …
