Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.
An electrode’s name depends on the circumstances. Confused? It may help to consider which electrochemical reaction is natural — and which is not.
When atoms get an electric charge, they act very differently. Now called ions, these are behind many aspects of chemistry, including acids and batteries.
Snot oozed by a marine tube worm can glow for up to 3 full days. The secret of how this works might lead to long-lasting lights that glow on and on.
Microbes can live in a hydrogen atmosphere. This points to new space worlds that host alien life.
Scientists blasted a tiny capsule of hydrogen with laser beams, setting off a reaction that released more energy than in earlier experiments. Still, scientists remain a long way from creating a reaction that releases more energy than it needs to get started.
