Not exact matches

Kanzius had essentially replicated the centuries - old method of water electrolysis, separating water into hydrogen and oxygen gases by running a current through water loaded with salt, which makes it conductive.

A low - voltage current applied to the electrodes drives a catalytic reaction that separates molecules of H2O, releasing bubbles of hydrogen on one electrode and oxygen on the other.

Once the nanoparticles are added and light applied, the water separates into hydrogen and oxygen almost immediately, producing twice as much hydrogen as oxygen, as expected from the 2:1 hydrogen to oxygen ratio in H2O water molecules, Bao said.

«Splitting water usually requires two different catalysts, but our catalyst can drive both of the reactions required to separate water into its two constituents, oxygen and hydrogen,» says study leader Associate Professor Chuan Zhao.

Rechargeable batteries are too heavy for the job, so engineers are planning to try a technology that would use current to separate water into oxygen and hydrogen during the day, and then reverse the process at night via fuel cells to produce electricity.

Superimposed on that are rectangles showing four steps of photosynthesis in extreme close - up: molecules of water going into the roots; yellow dots of sunlight filling a green chlorophyll vessel; energy emanating from one side of the chlorophyll vessel and splitting the water into two separate streams of oxygen and hydrogen; and energy emanating from the other side of the chlorophyll vessel, which demonstrates how the sun's energy is «trapped as little packets.»

As they become anoxic, many species begin to die off, and the chemocline which separates oxygen rich waters above from the hydrogen sulfide rich waters below will rise toward the surface eventually spewing the poisonous gas into the atmosphere and wiping out countless species...... possibly our own.
