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, ...

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

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 ...

"Opposites charges attract; like charges repel" is a fundamental principle of basic physics. But a new study from Oxford University, published today in Nature Nanotechnology, has demonstrated that ...
