Sentences with phrase «where oxygen atoms»

They took a common defect called a neutral oxygen vacancy — a place where an oxygen atom should appear in the lattice but instead two electrons are trapped.

A neutral oxygen vacancy, a place where an oxygen atom should appear in the lattice but is instead replaced by two electrons, is represented by the yellow shape, which depicts the charge density of those electrons.

The researchers determined that the holes became trapped in «oxygen vacancies» — places within the crystal lattice where an oxygen atom is missing.

Not exact matches

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.

Spinels consist of densely packed, highly symmetrical planes of oxygen atoms (somewhat like a densely packed box of marbles) where different metallic elements are lodged in the spaces between them.

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.

The voltage injects electrons into the oxygen atoms, allowing them to break free from titanium's hold and travel to the electrode, where they pick up carbon atoms from the graphite to form carbon dioxide.

Many members of the team had previously reported uranium nitride and oxo complexes where the molecules are essentially the same except for swapping a single nitrogen atom for an oxygen.

The etching is done in a plasma chamber where the diamond is bombarded by argon and oxygen ions, ripping the carbon atoms out of the diamond crystal.

Specifically, they are interested in those genes that are involved in tyrosine phosphorylation — the attachment of a phosphate group (a phosphorous surrounded by oxygen atoms) to distinct sites in protein chains where there is a tyrosine residue.

A molecule containing three oxygen atoms, computer models suggest that ozone on Venus is formed when sunlight breaks up carbon dioxide molecules and releases oxygen atoms, which are swept around to the planet's nightside by winds where they can then combine to form unstable, three - atom ozone molecules, as well as much more stable, two - atom molecules essential for animals.

Ozone - depleting substances are emitted by human activity at the planet's surface and eventually travel to the stratosphere, where there the chlorine atoms and certain other constituent parts break apart the three oxygen atoms that make up an ozone molecule.
