Charge ordering. Charge ordering (CO) is a (first- or second-order) phase transition occurring mostly in strongly correlated materials such as transition metal oxides or organic conductors. Due to the strong interaction between electrons, charges are localized on different sites leading to a disproportionation and an ordered superlattice.
Two unnamed former Bush administration officials say the briefing was detailed and graphic, and at the time she did not raise substantial objections. One unnamed U.S. official present during the early briefings said, "In fairness, the environment was different then because we were closer to September 11 and people were still in a panic. But ...
In a "future episode", it is shown Lenny is once again in charge of the power plant. On one occasion, it is implied he is an undercover agent whose target is Homer. At the Adult Education Annex, Lenny teaches a class on "How To Chew Tobacco". In one of Homer's daydreams, it is shown that Lenny is the President of the United States.
The next trillion-dollar stocks: Who are the world’s next largest companies? Nvidia made a huge splash as it skyrocketed in the last couple years to become a trillion-dollar stock. It now sits ...
Trickle charging. Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, thus enabling the battery to remain at its fully charged level; this state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
Charged current interactions are the most easily detected class of weak interactions. The weak force is best known for mediating nuclear decay. It has very short range, but is the only force (apart from gravity) to interact with neutrinos. The weak force is communicated via the W and Z exchange particles. Of these, the W-boson has either a ...
A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless particles that always move at the speed of light ...
Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
