A transcritical cycle is a thermodynamic cycle where the working fluid goes through both Subcritical and supercritical states. It is a cycle with a maximum…

Compressed hydrogen (CH2, CGH2 or CGH2) is the gaseous state of the element hydrogen kept under pressure. Compressed hydrogen in hydrogen tanks at 350 bar…

Slush hydrogen is a combination of liquid hydrogen and solid hydrogen at the triple point with a lower temperature and a higher density than liquid…

Addition Reaction is a chemical reaction in which one molecule is added to another. An addition reaction, in organic chemistry, is in its simplest terms…

Hydrogen Safety covers the safe production, handling and use of hydrogen – particularly hydrogen gas fuel and liquid hydrogen. The main concern in working with…

Liquid hydrogen is the liquid state of the element hydrogen. Hydrogen is found naturally in the molecular H2 form. It is light and has fewer…

In chemistry, an open-chain compound or acyclic compound is a compound with a linear structure, rather than a cyclic one. They are those in which…

Chemical kinetics is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is the description of the rate…

Activation energy The minimum energy which must be available to a chemical system with potential reactants in order to result in a chemical reaction. Activation…

Coordination complex is a structure that forms because of a collision between molecules while new bonds are formed. It is the product of a Lewis…

An activated complex is the structure that results in the maximum energy point along the reaction path. It is an intermediate structure formed in the…

A base anhydride is an oxide of a chemical element from group 1 or 2 (the alkali metals and alkaline earth metals, respectively). It is…
