This belief was shattered in 1933 by the discovery that a superconductor is highly diamagnetic; that is, it is strongly repelled by and tends to expel a magnetic field.
Nobody has proved mathematically that this "Hubbard model" of strongly repelling electrons hopping around in planes produces superconductivity.
(vi) Most transition-metal 3d solutes do not bind strongly with vacancies, and some are even energetically strongly repelled from vacancies, particularly for the early 3d solutes, Ti and V.
Following Newton, Hales believed "forces of attraction and repulsion" to be the basis of physical nature, and through various chemical experiments he demonstrated that solid concretions, including bladder stones, were compounds that had locked within themselves large quantities of "air," which normally manifests a strongly repelling force.
Another scenario is the case where a propensity to local ordering (possibly a strict one) applies at the local level (typically two ions strongly repelling each other), but where the concentration of defects is such that this local ordering does not propagate further than a few atomic shells.
The findings of the study suggest that the action of negative air ionizers significantly alters the electrostatic landscape of the clinical environment, and that this has the potential to cause any Acinetobacter-bearing particles in the air to be strongly repelled from some plastic surfaces and attracted to others.
Our findings suggest that it is possible that the action of negative air ionizers in this setting changed the electrostatic characteristics of plastic items of equipment within the ICU environment, causing airborne particles to be strongly repelled from some surfaces or attracted to others.
It is well known that SDS binds extensively with proteins (Turro et al. 1995) and thereby provides an exclusively anionic SDS/protein complex, and that this complex would be expected to be strongly repelled from the anionic surface of silica at neutral pH.
The two-year-old sweated up in the preliminaries and drifted to odds of 6-4 but finished strongly to repel the challenge of the favourite, Leo Minor, from the powerful Ballydoyle stable of O'Brien Sr. Justice Frederick will now give the younger man a real chance of Royal Ascot success next week when he lines up in the Chesham.
