WebDynamic covalent chemistry (DCvC) is a synthetic strategy employed by chemists to make complex supramolecular assemblies from discrete molecular building blocks. DCvC has allowed access to complex assemblies such as covalent organic frameworks , molecular knots , polymers , and novel macrocycles . [2] A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each atom to attain the equivalent …

Alex is coping with his father's death and, at the start of the film, is unenthusiastic about traveling to Mexico to be with his extended family. However, while he's there, he forms a strong bond with his grandfather and cousins. Web12 mrt. 1999 · The mechanical stability of covalent bonds has been investigated indirectly in ensemble measurements or by flow-induced chain fracture in liquids ( 1 ). The development of nanoscale manipulation techniques ( 2) has made it possible to directly address single atoms or molecules and probe their mechanical properties. green hedgehog from sonic
