The radiation environment near Earth remains a challenging topic of study due to its complex dynamics, spanning multiple energy and temporal scales. During ...

Engineers at Northwestern University have unveiled the behavior of single microscopic particles when they unite.

pt. I. General principles.--pt. II. Dynamics of rigid bodies.--pt. III. Theory of the potential, dynamics of deformable bodies ...

Scientists didn’t understand why independently oscillating microscopic particles suddenly begin moving in perfect sync when grouped together. Researchers showed that fluid-driven hydrodynamic ...

Cohesion is often seen as a key factor to bulk powder flowability and is frequently blamed for problems in powder processing. Particles attract to one another in cohesive powder to create agglomerates ...

Several years ago, scientists discovered that a single microscopic particle could rock back and forth on its own under a ...
