Curiosity Rover finds high levels of methane on Mars

A team working with NASA to study data the Mars Curiosity Rover has found high levels of methane at a site on the Red Planet. The existence of methane is, of course, a possible sign of life, since it is produced in abundance ...

Energy researchers break the catalytic speed limit

A team of researchers from the University of Minnesota and University of Massachusetts Amherst has discovered new technology that can speed up chemical reactions 10,000 times faster than the current reaction rate limit. These ...

We finally understand how oxygen reacts on platinum

Platinum is a widely used catalyst, but its precise mechanism largely remains a mystery to scientists. Ludo Juurlink has now demonstrated for the first time how oxygen reacts on the platinum surface. Together with Ph.D. students ...

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.
