Algae-inspired polymers light the way for enhanced night vision

In a study recently published in ACS Applied Polymer Materials, researchers from the University of Tsukuba synthesized an infrared-transmitting polymer—based on low-cost, widely available materials—that retains its shape ...

Researchers develop new atomic layer deposition process

A new way to deposit thin layers of atoms as a coating onto a substrate material at near room temperatures has been invented at The University of Alabama in Huntsville (UAH), a part of the University of Alabama System.

Solar hydrogen: Let's consider the stability of photoelectrodes

Hydrogen is a versatile fuel that can store and release chemical energy when needed. Hydrogen can be produced in a climate-neutral way by the electrolytic splitting of water into hydrogen and oxygen using solar energy. This ...

New catalyst turns greenhouse gases into hydrogen gas

A new nanocatalyst that recycles major greenhouse gasses, such as carbon dioxide (CO2) and methane (CH4), into highly value-added hydrogen (H2) gas has been developed. This catalyst is expected to greatly contribute to the ...

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.
