chemical reaction

Even worse, though, a chemical reaction that was occurring in the high heat of the reactor core was producing highly flammable hydrogen gas.

Specific regions of DNA known as phosphates act like tiny "hands" that guide chemical reactions to form the correct mirror-image version of a compound.

These properties are critical in determining how effectively a material can catalyze chemical reactions.

Other studies support the idea that energetic solar events and their resulting particles may have triggered chemical reactions that produced biomolecules and greenhouse gases -- key ingredients for sustaining life.

"With this method, we have turned the ammunition casing into an electrode, allowing us to drive chemical reactions at the surface of the casing," said Dr. McKeever.
