Next, a photoredox catalyst
strips a hydrogen atom equivalent from the carbon, and the thiol engages in radical chemistry to transfer the deuterium or tritium in its place.
Not exact matches
Due to the high temperatures and intense radiation present, these
atoms initially existed in an «ionized» state: The negatively charged electrons had been
stripped from positively charged protons, leaving behind positive
hydrogen ions (essentially, just protons).
If high - energy particles from deep space, called cosmic rays, happened to hit one of those
hydrogen atoms, it became ionized,
stripped of its electron.
The second - stage reaction
strips off the fatty acids» carboxyl group (a carbon
atom, two oxygen
atoms, and a
hydrogen atom) and breaks the remaining hydrocarbon chains into smaller fragments, yielding a light oil.
This region is made up of
hydrogen plasma, a gas of
atoms whose electrons have been
stripped away by the ferocious temperature, leaving just protons behind.
Such views suggest that tiny galaxies in the early universe played a crucial role in cosmic reionization — when ultraviolet radiation
stripped electrons from
hydrogen atoms in the cosmos.
Again, the first one
stripped off
hydrogens from adjacent carbon
atoms in both the long polyethylene chains and short alkanes to form double bonds; the second split the molecules and randomly stitched split molecules back together.
The energetic radiation from these new stars
strips electrons from the
atoms within the surrounding
hydrogen gas, ionising it and producing a characteristic red glow.
As the starshine intensified, it eventually
stripped electrons from the
hydrogens, ionizing the
atoms.
The ionized
hydrogen, with
atoms violently
stripped of their electrons, seems to fill the interior of the superbubble while the neutral
hydrogen forms its walls and cap.
That blistering heat
stripped light - emitting electrons from the
hydrogen atoms in the plasma, eliminating light as a source of information about the atomic nuclei, or ions, in the plasma and creating the need for a new diagnostic tool.
Before this detector was built, astrophysicists would have said that cosmic rays are almost universally protons — that is,
hydrogen atoms stripped of their electron so that they are bare, charged protons traveling across the universe.
Specifically, he has examined hydroxyl radicals, which are water molecules
stripped of one
hydrogen atom.
