Membrane folds may also trap or exclude tags. Analysis in 2D of movement on non-flat cellular membranes can cause simple diffusion to show apparently complex patterns that necessitate complex ...

The Stokes-Einstein equation provides a quantitative description of this diffusion process, particularly under conditions where the fluid's viscosity and the particle's size significantly influence ...

Tiny particles are opening big doors for medicine, materials science, and even environmental cleanup. Across the world, ...

Join Dr. Na Li as she explores the mysteries of the particle drifting effect and its practical applications in real-world ...

Save guides, add subjects and pick up where you left off with your BBC account. Diffusion is the movement of particles from a region where they are in high concentration to a region where they are ...

As well as diffusion occurring between different regions ... Osmosis refers to the movement of water molecules only. The image shows an example of osmosis showing the direction of movement ...
