Implantable batteries can run on the body's own oxygen

From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and to dampen pain. But batteries eventually run low and require invasive surgeries to replace.

Researchers observe salt dissolution at the atomic level

A research team, affiliated with UNIST has achieved a groundbreaking feat by observing the dissolution of salt in water at the atomic level and experimentally uncovering the underlying principle.

With living robots, scientists unlock cells' power to heal

Near the entrance to Michael Levin's lab at Tufts, four deer antlers are mounted on wooden boxes. They represent an incredible feat of regeneration in mammals: Deer shed their antlers annually and regrow the bone, blood vessels, ...

New method for analyzing nanoporous materials

In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure. This applies to high-tech ...

Ion

An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge. The name was given by physicist Michael Faraday for the substances that allow a current to pass ("go") between electrodes in a solution, when an electric field is applied. It is from Greek ιον, meaning "going".

An ion consisting of a single atom is an atomic or monatomic ion; if it consists of two or more atoms, it is a molecular or polyatomic ion.
