Mechanochemistry refers to the chemical transformations that occur during mechanical treatments of substances, including grinding, milling, or crushing. There are several other terms that can be used for this field of study, such as mechanosynthesis, solid-state chemistry, and mechanochemical synthesis. Solid-state chemistry is more widely used in the scientific community because it describes the physical and chemical properties of solid materials. Mechanochemical synthesis emphasizes the production of new materials and chemical reactions that occur during the mechanical treatment of solids. Another term, "grind chemistry," has been used in the past but is now less common. Regardless of the term used, mechanochemistry is an exciting research area that has the potential to revolutionize materials science and chemical engineering.
