|A biofuel is a hydrocarbon that is made by a living organism that we humans can use to power something. This definition of a biofuel is rather formal.Any hydrocarbon fuel that is produced from organic matter in a short period of time is considered a biofuel. This shows with fossil fuels, which take millions of years to form and with other types of fuel which are not based on hydrocarbons.
Biofuels are tricky to understand is that they need not be made by a living organism, though they can be. Biofuels can also be made through chemical reactions, carried out in a laboratory or industrial setting, that use organic matter to make fuel. The only real requirements for a biofuel are that the starting material must be CO2 that was fixed by a living organism and the final fuel product must be produced quickly and not over millions of years.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most 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. 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.
