Origin of massive methane reservoir identified

New research from Woods Hole Oceanographic Institution (WHOI) published Aug. 19, 2019, in the Proceedings of the National Academy of Science provides evidence of the formation and abundance of abiotic methane—methane formed ...

Circulation of water in deep Earth's interior

Phase H is a hydrous mineral that is considered to be an important carrier of water into deep Earth. We determined the dissociation condition of phase H by a theoretical calculation based on quantum mechanics. Phase H decomposes ...

Scientists create the world's thinnest gold

Scientists at the University of Leeds have created a new form of gold which is just two atoms thick—the thinnest unsupported gold ever created.

Researchers enrich silver chemistry

Researchers from the Moscow Institute of Physics and Technology have teamed up with colleagues in Russia and Saudi Arabia and proposed an efficient method for obtaining fundamental data necessary for understanding chemical ...

Removing carbon dioxide from power plant exhaust

Reducing carbon dioxide (CO2) emissions from power plants is widely considered an essential component of any climate change mitigation plan. Many research efforts focus on developing and deploying carbon capture and sequestration ...

Performing chemistry in floating droplets

Could chemists be ready to ditch the venerable test tube, the very symbol of chemistry in the minds of many people? Maybe not quite yet, but Caltech's Jack Beauchamp is working on it.

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.
