Sentences with phrase «oxygen bond forms»

With the combination of in situ synchrotron infrared spectroscopic measurements carried out at high pressure, and ab initio calculations on the ferromagnesite structure, it was possible to identify a unique vibrational signature present only in the high - pressure phase, and thus a new carbon - oxygen bond forms in ferromagnesite under pressure.

Not exact matches

Oxygen itself is chemically «reduced» in the process, taking up the liberated electrons and using them to form new bonds and molecules.

During use, lithium ions stored in the graphite flow to the lithium - based electrode, where they form chemical bonds with oxygen atoms, a reaction that generates an electric current.

«That's what his advance is pointing towards,» he says, «finding an alternative catalyst that will allow us to do oxygen evolution (breaking the bonds of water or H2O and forming oxygen) in concert with hydrogen» on a grand scale.

It's called oxidizing because it causes the molecule to undergo a reaction in which it combines with oxygen, breaking C - H bonds and forming new carbon - oxygen bonds.

Atoms of most elements, such as hydrogen, oxygen and carbon, form tight chemical bonds by sharing electrons with their neighbours in order to give each atom a stable configuration of electrons.

Of the two types of atom, oxygen has more pull on the electrons that they share to form the bonds between them, so the oxygen becomes slightly negatively charged and the hydrogens slightly positive.

«Catalysts have to be able to select between different C - H bonds and form new carbon - oxygen, carbon - nitrogen or carbon - fluoride bonds, for example,» Garcia - Bosch said.

The researchers discovered that these catalysts — copper in the form of a white salt and the ligand as an oil — can oxidize C - H bonds in a very efficient way in combination with hydrogen peroxide, a reduced form of oxygen that nature uses.

The chemical feature that enables this suppression is a bond between two oxygen atoms — an unstable peroxide bridge that releases a tiny barrage in the form of free radicals (unpaired electrons) that can fracture parasite proteins the way an F5 twister tears apart barns.

Water, for example, with one oxygen and two hydrogen atoms, can form two hydrogen bonds per molecule.

In this case, they form naturally as ozone — a high - energy oxygen molecule — reacts with carbon chains that have double bonds, forming a compound that has two reactive pairs of electrons.

Aspirin, for example, contains just 21 atoms (nine carbons, eight hydrogens and four oxygens) bonded together to form a particular shape.

Astronomers predicted that as the gas cooled after the explosion, large amounts of dust would form as atoms of oxygen, carbon, and silicon bonded together in the cold central regions of the remnant.

However, in Cu - SSZ - 13, the copper metal bonded with both the nitrogen and the oxygen halves of the nitric oxide barbell, as if the copper and nitric oxide formed a three - membered ring.

Jansone - Popova created the saturated form of the preorganized ligand — a cyclic amide containing a nitrogen atom and a carbon double - bonded to oxygen.

The polymer and the agent form hydrogen bonds, weak electrostatic connections between polymer's hydrogen and an agent's oxygen atom.

But atoms that typically form only two chemical bonds, such as oxygen, don't often make long, polymer - like chains.

They are called «poly», because they contain many double bonds which tend to react with oxygen when heated and form harmful compounds such as free radicals.

An additional benefit for both the community and the rest of the world is that the trees and the soil in their forest contain large quantities of carbon, which bonds with oxygen to form the greenhouse gas carbon dioxide when released into the atmosphere.

When an electrically excited free oxygen atom encounters an oxygen molecule, they may bond to form ozone.

But when their temperature is lowered and they form a water molecule, the symmetry of the individual atoms is broken as they form a molecule with 105 degrees between the hydrogen - oxygen bonds.
