WEST LAFAYETTE, Ind. — Scientists have long suspected that a quantum phenomenon might play a role in photosynthesis and other chemical reactions of nature, but don’t know for sure because such a ...

We are all made from stars. And that's not just a beautiful metaphor. Apart from hydrogen, as many have heard from the Carl Sagan and Neil DeGrasse Tyson Cosmos series, every ingredient in the human ...

Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. In Chapter 5, students learned how the process of dissolving ...

Researchers demonstrate a chemical reaction produced through an intermediary created by a separate chemical reaction, findings that could impact environmental remediation and fuel production. A ...

Controlling the products and byproducts of a chemical reaction is called selectivity. Scientists are trying to find better ways to control selectivity in industrial chemical reactions to improve the ...

Scientists have observed so-called 'roaming' chemical reactions, those that at certain points move away from the lowest minimum energy 'path of least resistance', in highly excited energy states for ...

Calcium carbonate is a chemical found in eggshells, seashells, and many other materials. Observe how calcium carbonate reacts with common liquids. A Plaster Master or a Plaster Disaster Plaster is ...
