Sentences with phrase «charged oxygen molecules»

Not exact matches

There, the charged particles strike molecules in Earth's atmosphere that release photons of various colors (red hues come from oxygen, for example) and light up polar regions in frequent auroral displays.

Unlike water or regular ice, in superionic ice the water molecules dissociate into charged atoms called ions, with the oxygen ions locked in a solid lattice, while the hydrogen ions move like the molecules in a liquid.

The gamma rays strip electrons from the molecules in the surrounding air, and the resulting free electrons lose energy and readily attach to oxygen molecules to create elevated levels of negatively charged oxygen ions around the radioactive materials.

These oxygens have a partial negative charge (as in the molecule of water) and the oxygen atom attracts the electrons of the bonds more effectively.

The mechanism of the subsequently applied relatively new cooling technique relies on the fact that these molecules exhibit a permanent electric dipole moment (i.e. the negative charge is shifted towards the oxygen atom).

Water molecules are made up of one negatively charged oxygen atom and two positively charged hydrogen atoms.

Opposite charges attract, so water molecules tend to stick to each other as a positive hydrogen atom of one molecule attaches itself to the oxygen atom of its neighbour.

Plasma causes the neutrally charged oxygen and nitrogen molecules in the air to become electrically charged.

Gold / titanium dioxide catalyst in action: At the interface between a gold particle (Au, gold) and the titanium dioxide surface (TiO2, red and light blue), an oxygen molecule (O2, dark blue spheres) is activated by a charge transfer and becomes catalytically active.

The researchers tested a variety of solutions containing the soil bacteria Geobacter sulfurreducens and Thiobacillus denitrificans, which thrive by eating acetate (an organic compound that makes vinegar sour) and nitrate (a negatively - charged molecule of biologically available nitrogen and oxygen), respectively, when they can find a spare electron or two.

In particular, a charged molecule called hydronium, which has three hydrogen atoms and one oxygen ion, can transform into water (plus an independent hydrogen atom) if it captures a free - floating electron.

In the typical setup, air is fed to the negatively charged electrode, or cathode, where oxygen molecules pick up extra electrons.

Kinases and phosphatases are enzymes that add or remove, respectively, negatively charged phosphate - oxygen groups to other molecules in the cell.

When an oxygen molecule (O2) becomes electrically charged or «radicalized» it tries to steal electrons from other molecules, causing damage to the cell's DNA.

When an oxygen molecule becomes electrically charged or «radicalized» it tries to steal electrons from other molecules, causing damage to the DNA and other molecules.

Because it has positive (hydrogen) and negative (oxygen) charges, it sticks or bonds to other water molecules.

«The net effect of this is that, although the total electronic charge on the molecule balances the total nuclear charge, each oxygen atom carries a small net negative charge, and a balancing positive charge is associated with the carbon atom.

These free charges split water molecules into hydrogen and oxygen.
