Silica particles, when mixed into liquid crystals, can act a lot like individual atoms. The geometry of the particles determines how they interact with each other the same way the electrons around an ...

A new study published in Nature Nanotechnology has shown that long-range attraction between similarly charged particles in solution is possible. Remarkably, the group also discovered that, depending ...

Atoms are the building blocks of matter. Everything around us — from air and water, to rocks, plants and animals — as well as everything within our bodies, is made up of atoms. They are very small, ...
