Particle transport refers to the movement of particles, such as ions, molecules, or cells, through a medium or environment. This research area examines the mechanisms and factors affecting the transport of particles, including diffusion, advection, and convection. Scientists study particle transport in various fields, such as environmental science, cell biology, and materials science, to understand how particles move through different systems and environments. This research is important for addressing issues such as pollution, drug delivery, and material transport in industrial processes.
