It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...

From a young age, we are taught in school that like charges – whether both positive or both negative – will repel each other, while opposite charges attract. It turns out that under certain conditions ...

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, ...

It's a problem that has stumped scientists for years. Now researchers have developed a model that can predict the movements of charged particles, even in heterogeneous environments like cells, blood, ...

The measurement of particle size, and understanding how products and processes are affected by this, can be critical to the success of many manufacturing businesses. Particles are 3D objects and ...

The study found that negatively charged silica microparticles suspended in water attracted each other to form hexagonally arranged clusters. Image credit: Cover image: Zhang Kang. A study published ...
