Thus particles actually never meet: at very short distances the mutual force between them is repulsive, and increases indefinitely as the distance is diminished. At great distances, particles ...

Natural dispersion forces acting between molecules and particles arise from electromagnetic fields generated by quantum and thermal fluctuations. Here, Brügger et al.show that isotropic ...

A study shows that similarly charged particles can sometimes attract, rather than repel. The team found that like-charged particles suspended in liquids can attract one another at long-range ...

When more gas particles enter a container, ... but there are very tiny mathematical deviations due to differences in actual particle size and tiny intermolecular forces in real gases.

Investigating forces in more complex geometries, such as between a particle and a surface or between two particles, requires significant modifications to the instrument. Despite these limitations, ...

For scurrying upside down on smooth ceilings and other gravity-defying feats, lizards known as geckos may exploit intermolecular forces between the surface and billions of tiny stalks under their ...
