Understanding the behavior of materials at their interfaces — where they connect to and interact with other materials — is central to engineering a variety of devices used to process, store and ...

This video explains covalent bonding. A covalent bond is a shared pair of electrons. Covalent bonding forms molecules. Substances with small molecules have low melting and boiling points and do not ...

Chemical bonding is the force of attraction that holds atoms together to form molecules or compounds. There are two primary types of chemical bonds: ionic and covalent bonds. Both these bonds play a ...

A reversible covalent reaction in which two oxygen-insensitive radicals combine to form a carbon–carbon bond provides the mechanism by which a polymer gel can self-heal at room temperature without the ...

Silica has a giant covalent structure containing silicon atoms (grey) and oxygen atoms (red) Learn more on properties of giant covalent compounds in this podcast. Listen to the full series on BBC ...
