Neutrons are one of the main building blocks of atoms and have no electric charge.
These positively charged particles are important building blocks in atoms.
Ultraviolet light, sulfite and iodide break down these PFAS molecules faster and more thoroughly than other methods.
Scientists 3-D printed the new fabric, which has even more tricks up its sleeve — such as conducting electricity and resisting radio waves.
Researchers have developed a liquid metal that breaks down carbon dioxide in the air, converting it from a climate threat into a valuable raw material.
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.
A fat molecule's three long chains of carbon and hydrogen atoms repel water, stash energy and keep living things warm — even in the bitter cold.
These two strange ingredients could make skin-care products that are better for both our skin and the environment.
Metals can bend and pull without snapping, and conduct electricity. The reason: Their atoms tend to lose electrons to neighboring atoms.
About a dozen calves have been trained to pee in a stall. Toilet training cows on a large scale could cut down on pollution, scientists say.
