Catalyst renders nerve agents harmless

A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has studied a catalyst that decomposes nerve agents, eliminating their harmful and lethal effects. The research ...

Driving chemical reactions by remote control

Students learn in high school that molecules must be in contact to react chemically. But what if that's not always true? It's that idea, which challenges textbook "laws," a team of theorists explored. They showed that even ...

Chemists take a closer look at the spot where water meets air

Water, despite its central place in so many processes vital to life on Earth, remains a chemical mystery in many respects. One of those mysteries is the nature of water at the exact point where it comes into contact with ...

Salt takes a quick step before falling out of water

When a drop of sea spray lands on a rock and heats under the midday sun, the salt crystalizes and falls out of the evaporating water as a crystal—helping to power the Earth's atmosphere and leaving a delicious kernel of ...

Scientists develop way to identify topological materials

In the decades since they were first theorized, scientists have suggested that the exotic properties of topological materials—that is, materials that maintain their electrical properties even in the face of radical temperature ...

Green plastic production made easy

A one-step method enables scalable and more environmentally friendly production of plant-derived plastic monomers, paving the way towards the mass production of a sustainable alternative to petroleum-based materials.

Chemical reaction

A chemical reaction is a process that always results in the interconversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Classically, chemical reactions encompass changes that strictly involve the motion of electrons in the forming and breaking of chemical bonds, although the general concept of a chemical reaction, in particular the notion of a chemical equation, is applicable to transformations of elementary particles, as well as nuclear reactions. Different chemical reactions are used in combination in chemical synthesis in order to get a desired product. In biochemistry, series of chemical reactions catalyzed by enzymes form metabolic pathways, by which syntheses and decompositions ordinarily impossible in conditions within a cell are performed.
