Sentences with phrase «uranium atoms in»

Deep underground, uranium atoms in rocks undergo radioactive decay, sending off alpha particles — two protons and two neutrons — that can bump into other molecules and change them.

Not exact matches

The nuclear power plants in use around the world today use fission, or the splitting of heavy atoms such as uranium, to release energy for electricity.
there's really no room for the concept of an independent entity possessed of «will» in a worldview shaped by cause and effect; the only place for «will» to retreat to is the zone of true randomness, of complete uncertainty, which means that truly free will as such must be completely inscrutible [sic]... Statistical laws govern the decay of a block of uranium, but whether or not this atom of uranium chooses to fission in this instant is a completely unpredictable event — fundamentally unpredictable, something which simply can not be known — which is equally good evidence for the proposition that it's God's (or the atom's) will whether it splits or remains whole, as for the proposition that it's random chance.
A good example of this is the uranyl, -LCB- UO2 -RCB- 2 + ion which is widely prevalent in the environment naturally and also nuclear waste where the two oxygen atoms reside opposite each other and are bonded very strongly to the uranium.
Since neutrons traveling through heavy water split atoms more efficiently, less uranium should be needed to achieve a critical mass; that's the minimum amount of uranium required to start a spontaneous chain reaction of atoms splitting in rapid succession.
Every time an incoming neutron bombards one of the uranium atoms, the atom splits in two, expelling energy and releasing more neutrons, which in turn collide with other atoms and establish a chain reaction.
The competing SFR design banks on a novel fission concept: bombarding uranium atoms with neutrons of much higher energy than those used in a traditional nuclear plant.
The water contains a smattering of uranium atoms that decay into a distinctive isotope of thorium, which accumulates in the calcite over millennia.
What is more, the uranium atoms that have already split in two produce radioactive by - products that themselves give off a great deal of heat.
Such uranium deposits in Canada, Australia and Kazakhstan comprise the bulk of the world's known supply — although uranium is a ubiquitous atom that can even be derived from seawater.
When the clusters form, each contains 20 to 60 uranium atoms, «so we can extract them in whole bunches instead of one at a time,» Nyman said.
This weakens uranium's grip on the other oxygen, the researchers report tomorrow in Nature, allowing it to react with one of the new molecule's silicon atoms.
The potassium - atom mouth of an organic molecule grabs one of the oxygen atoms (red) in uranium dioxide.
While visiting the production site for highly - enriched uranium in Oak Ridge, Tenn., during the 1940's, for example, Feynman was surprised to see stocks of that fissionable material deliberately stored in separate rooms, but on an adjoining wall that posed no barrier to collisions involving atoms of uranium and escaping neutrons on both sides.
In uranium dioxide, the oxygen atoms - key corrosion creators - do not diffuse randomly through the material.
First one neutron splits one uranium atom which in the process of splitting releases 2 neutrons.
That's because far more energy is trapped in uranium atoms than in the chemical bonds within wood, coal, oil, or natural gas.
Note well that solving for the exact, fully correlated nonlinear many electron wavefunction of the humble carbon atom — or the far more complex Uranium atom — is trivially simple (in computational terms) compared to the climate problem.
