|Chemical engineering is a branch of engineering that applies the natural sciences and life sciences together with mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy. A Chemical engineering journal is a periodical publication intended to further progress of science, usually by reporting new research. Most Chemical engineering journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Chemical engineering Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
