A sudden shift of temperature, sunshine, or whatever, might eliminate several land-based species, but unless all the oceans froze (for which we have no evidence) the seagoing dinos (of which there were plenty) would simply have migrated to somewhere warmer or colder that suited them.
The reason for the lowering of the DOS at the Fermi level below the free electron value is the hybridization of the narrow d band with the much broader sp band. This opens the so-called Fano gap in the sp density of states, pushing states from the middle of the sp band to the edges. However, the overall (sp+d) density of states has no deep or pronounced local minimum at the Fermi energy.
Hi Halc. That explains that then! It's a typical knee jerk reaction from a newbie like myself when he thinks, hey something DOES travel faster than light! I guess that if the article was aimed at a non scientist like myself then it would have said the neutrinos get to Earth earlier than the light 'because ...'.You too can travel faster than the speed of light, quite easily actually.
A storm descends on a small town, and the downpour soon turns into a flood. As the waters rise, the local preacher kneels in prayer on the church porch, surrounded by water. By and by, one of the townsfolk comes up the street in a canoe.
"Better get in, Preacher. The waters are rising fast."
"No," says the preacher. "I have faith in the Lord. He will save me."
Still the waters rise. Now the preacher is up on the balcony, wringing his hands in supplication, when another guy zips up in a motorboat.
"Come on, Preacher. We need to get you out of here. The levee's gonna break any minute."
Once again, the preacher is unmoved. "I shall remain. The Lord will see me through."
After a while the levee breaks, and the flood rushes over the church until only the steeple remains above water. The preacher is up there, clinging to the cross, when a helicopter descends out of the clouds, and a state trooper calls down to him through a megaphone.
"Grab the ladder, Preacher. This is your last chance."
Once again, the preacher insists the Lord will deliver him.
And, predictably, he drowns.
A pious man, the preacher goes to heaven. After a while he gets an interview with God, and he asks the Almighty, "Lord, I had unwavering faith in you. Why didn't you deliver me from that flood?"
God shakes his head. "What did you want from me? I sent you two boats and a helicopter."
OK, is it possible to oxidise oxygen at the alkaline solution and reduce protons in the acidic solution?It is easy to reduce protons. It is very difficult (thermodynamically uphill, requiring energy input) to oxidize oxygen. Even if you meant oxidize water (or even hydroxide) to oxygen, that would require energy input.
So on both the acidic and alkaline side, there will be protons and electrons consumed but at different rate, right?one of the rates must be negative compared to the other (ie one side consumes protons and electrons, and the other produces them)
