Van der Waals forces, named after a Dutch scientist, refers to intermolecular forces of attraction that do not arise from the typical covalent or ionic bonds that keep molecules intact.
In recent years researchers have achieved better performance with compounds such as lithium borohydride, in which the metal atoms form weaker, ionic bonds with groups containing several hydrogen atoms.
Elementary chemistry distinguishes two kinds of strong bonds between atoms in molecules: the covalent bond, where bonding arises from valence electron pairs shared between neighboring atoms, and the ionic bond, where transfer of electrons from one atom to another leads to Coulombic attraction between the resulting ions.
In the above examples, the prenucleation cluster formation is a polymerization - like event, because the chemical bonds formed are mostly covalent (silica) to partly ionic (transition metals).
The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds.

Therefore, if the gel acquires a tiny crack as it stretches, the polyacrylamide grid helps to spread the pulling force over a large area, tugging on the alginate's ionic bonds and unzipping them here and there.
Provided the gel has some time to relax between stretches, the ionic bonds between the alginate and the calcium can «re-zip,» and the researchers have shown that this process can be accelerated by raising the ambient temperature.
