Sentences with phrase «as bonds between atoms»

Not exact matches

Also the conception of the constituent entities as «matter» provides nothing whereby there could be what are termed «valency bonds» between the atoms.

«We then studied the chemistry of these materials in greater detail and calculated the energy that would be needed to separate the layers, focusing primarily on materials where interactions between atoms of different layers are weak, something known as Van der Waals bonding,» says Marco Gibertini, a researcher at THEOS and the second author of the study.

Drying oils, such as linseed and walnut, are unsaturated; their fatty acids contain plenty of double bonds between pairs of carbon atoms.

It turns out that the answer lies in the interaction between the bonds that hold the atoms in the water molecule together and the much weaker bonds, known as hydrogen bonds, that are the glue holding groups of water molecules together.

By producing alternating layers weakly bonded between one another, each consisting of a single layer of atoms, this new material could serve as the elements of gates and other components in new, miniaturised 2D semiconductors.

As computer simulations show, this comparatively weak kind of interaction decreases the total energy of the system, and so a bond between the Rydberg atom and the other atoms inside the electronic orbit is created.

chemical bonds Attractive forces between atoms that are strong enough to make the linked elements function as a single unit.

For example, the hydrogen bonding interaction between the phenolic — OH and the o - methoxy groups in curcumin influences the O - H bond energy and H atom abstraction by free radicals, thus making it a better scavenger of free radicals compared to other curcuminoids such as BDMC.

Molecules like HBr and HCl which have a permanent dipole, resulting from an unequal sharing of the bonding electrons, have a dipole which oscillates as the bond distance between the atoms oscillate.

But when their temperature is lowered and they form a water molecule, the symmetry of the individual atoms is broken as they form a molecule with 105 degrees between the hydrogen - oxygen bonds.
