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).

This chummy behavior resembles how electrons pair up in materials that conduct current without resistance, known as superconductors, researchers report in a paper accepted in Physical Review Letters.

After discovering the anomalous superconducting transition, researchers made measurements that gave them insight into the underlying electron pairing.

In this theory, a Lewis acid is any chemical species that attracts free electron pairs.

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 results confirmed that it was the superconductivity in the tubes that was driving electron pairs together.

The exciton is the excited electron paired...

A few years ago, researchers from the University of Cambridge showed that it was possible to create electron pairs in which the spins are aligned: up - up or down - down.

Normally electrons pair up and cancel out each other's magnetism, but Hicks says the organic molecules used in the experiment were selected because they can tolerate extra electrons.

This boosts the energy level of electron pairs on the island, causing them to break their superconducting bond to one another and hop to a nearby probe, which then channels them to a detector.

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 research published in Science provides the first direct proof that such «orbital - selective» electron pairing takes place.

Scientists still don't know what holds electron pairs together so they can effortlessly carry current in high - temperature superconductors.

UNSW researchers show that it involves the splitting of electron pairs.

How far it goes in depends on the nature of the electron pairing, and changes as the material is cooled down further and further.

By contrast, when graphene was coupled to superconducting PCCO in the Cambridge - led experiment, the results suggested that the electron pairs within graphene were in a p - wave state.

In the paper, Glashow and Cohen point out that if neutrinos can travel faster than light, then when they do so they should sometimes radiate an electron paired with its antimatter equivalent — a positron — through a process called Cerenkov radiation, which is analogous to a sonic boom.

P - wave superconductivity has not been unambiguously seen yet since the anatomy of the electron pairs is difficult to establish.

Until a critical current is reached, a supercurrent can flow across the barrier; electron pairs can tunnel across the barrier without any resistance.

But in the new technique, the energy of the electron pairs decreases as the excitation hops from molecule to molecule, so Forrest and colleagues end up with lower energy red light.

Thus, like the bouncing tennis ball attached to the measuring device, the combination of equal but opposite spins makes the electron pair impervious to magnetic noise.

But because the electron pairs were not affected by external magnetic noise, the interactions between them could be measured with great precision.
