Sentences with phrase «electron pairs between»

At the annual meeting of the American Physical Society and in the 12 March issue of Physical Review Letters, Kociak and his colleagues at the French national research agency CNRS and the Russian Academy of Sciences in Chernogolovka showed that empty nanotubes can also carry electron pairs between nonsuperconducting electrodes (in this case, metal pads made from a sandwich of aluminum oxide, platinum, and gold).

Most significant was the September unveiling by Japanese researchers of a powerful linkage between two silicon atoms that share three pairs of electrons — a so - called triple bond.

They found that the two factors qualifying a material as a good catalyst are its hydrogen adsorption energy and the Lewis pair's hardness — a measurement of the difference between its ionization potential and electron affinity.

The zirconium sapped the loyalty of the electrons bonding the nitrogen pairs, weakening the link between the two atoms and letting hydrogen weasel in and latch onto the nitrogen.

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.

Superconductivity is characterised by the way the electrons interact: within a superconductor electrons form pairs, and the spin alignment between the electrons of a pair may be different depending on the type — or «symmetry» — of superconductivity involved.

In contrast, the relatively high - temperature superconductors are thought to work when electrons are paired at the average distance between them — and this is what was seen between the atoms in this fermionic condensate.

That measurement breaks the entanglement between the pair of electrons that she and Bob share.

Bonds between atoms routinely involve two electrons, like a pair of ballroom dancers.

Observations of the shock between this pair of clusters showed that the radio emission was connected to the galaxy's jet, so clearly the electrons must have been initially accelerated by the black hole and then reaccelerated by the shock waves.

Applying a brief voltage pulse to a control electrode allows the superconducting electron pairs to oscillate back and forth between the two locations, representing the one and zero of a digital system.

They designed a set of tiny superconducting electrical components that enabled single electron pairs to jump between a tiny bar - shaped metal island and a nearby metal reservoir.

The ideas they worked on together are now known as BCS theory and provide a description of the superconducting state in terms of interactions between pairs of electrons.

Because of the huge mass / density difference of the two materials, this pairing provides maximum contrast in the electron microscope and delineation was easily distinguishable between the particle core and shell.

In superconducting materials, a strong attractive force acts between the electrons, which pair up and can move throughout the material without resistance.

Here, we propose a dissipative scheme that achieves the preparation of pairs of nuclear spins in long - lived singlet states by a protocol that combines the interaction between the nuclei and a periodically reset electron spin of a nirogen - vacancy center with local radio - frequency control of the nuclear spins.
