Nanoparticles have applications as therapeutic agents for joint diseases such as osteoarthritis. But the role of nanoparticle diffusion in synovial fluid or the fluid inside the joint is incompletely ...

Diffusion in supercritical fluids characterises the rate at which molecules migrate under concentration gradients in a medium above its critical temperature and pressure. In this regime, fluid density ...

A study now published in Nature Communications brings remarkable insights into the enigmatic behavior of supercritical fluids, a hybrid state of matter occupying a unique space between liquids and ...

Supercritical fluids are crucial to understand giant planets such as Jupiter and Neptune, where similar states of matter may reign. A study now published in Nature Communications brings remarkable ...

What is the Stokes-Einstein Equation? The Stokes-Einstein equation is a fundamental relation in physics that describes the diffusion of spherical particles through a fluid with low Reynolds number. It ...

A new physics-informed AI framework turns MRI tracer data into detailed maps of brain fluid movement, revealing how slow diffusion and faster directed flow may shape the brain’s waste-clearing system.
