Sentences with phrase «ionic bonds»

Ionic bonds are a type of chemical bonding formed when two atoms, one positively charged and the other negatively charged, attract and hold onto each other. It's like a strong magnet pulling them together. Full definition
The alginate portion of the gel consists of polymer chains that form weak ionic bonds with one another, capturing calcium ions (added to the water) in the process.
The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds.

Instead, the spaghetti - like base units of the materials terminate in «ligand» groups that like to link to free zinc based groups through ionic bonding.
When stress is applied to the adhesive, those «sacrificial» ionic bonds break first, allowing the matrix to absorb a large amount of energy before its structure becomes compromised.
For this new study, Wong and his colleagues wanted to try creating structures with potentially reversible ionic bonds, which had never been done before using light - based 3 - D printing.

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.
The ionic bonds modify the crystalline structure in such a way that ionomers become very transparent resins that are also tough and highly resistant to solvents.
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.
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.
The term is generally reserved for complexes in which the metal ion is bound to two or more atoms of the chelating agent, although the bonds may be any combination of coordination or 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.
The oxygens on tannic acid have a negative charge so they can create an ionic bond with other molecules (like iron).
