· The directional- and strong-bonding yields materials that are rigid and hard, with high melting points. The low melting points of polymers come from the secondary bonds linking the polymer chains.

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...

Space debris is becoming an overwhelming problem. Between 2019 and 2023, SpaceX’s Starlink satellites made more than ...

A new straightforward way to make an injectable gel capable of releasing multiple drugs at specific speeds improves ...

Covalent bonds are strong bonds ... high melting points which conduct when molten or in solution but NEVER when solid. Ionic compounds dissolve in water easily, when they do this their lattice ...

The difference in electronegativity between two bonded atoms determines the bond's polarity, with a large difference indicating a polar covalent bond (e.g., H-F bond) and a small difference indicating ...

Prior to 2000, many drugs that formed a covalent bond with targets did so non-selectively, which often led to undesired side effects when compared to non-covalent drugs. This led to the belief that ...
