Aluminum oxide (Al2O3), also known as alumina, corundum, sapphire, or ruby, is one of the best insulators used in a wide ...

But what makes oxygen different from carbon? It is the number of protons in the nucleus of an atom that is the defining feature of the atom. It's what makes one element different from another.

Oxygen atoms trigger defects in titanium’s atomic structure, making the metal brittle.

A neutral water molecule comprises two hydrogen atoms bonded to a single oxygen atom, the entire structure bending to give the molecule a partially positive side and a partially negative side ...

This approach significantly enhanced the bonding strength between oxygen defect sites and single-atom precursors, successfully constructing a series of high-density SACs.
