The Chemistry Portal

Colourful solutions in test-tubes.
Welcome to the chemistry portal. Chemistry, from the Greek χημεία meaning "pour together", is a branch of science. Modern chemistry focuses on the study of elements of the world and the bonds between elements. Chemistry also deals with composition, structure, and properties of substances and the transformations that they undergo. In the study of matter, chemistry also investigates its interactions with energy and itself. Because of the diversity of matter, which is mostly in the form of compounds, chemists often study how atoms of different chemical elements interact to form molecules, and how molecules interact with each other.

Skeleton structure of Bupropion
Bupropion, previously known as amfebutamone, is an atypical antidepressant that acts as a norepinephrine and dopamine reuptake inhibitor, and nicotinic antagonist. Bupropion belongs to the chemical class of aminoketones and is similar in structure to the stimulant cathinone, to the anorectic diethylpropion, and to phenethylamines in general.

Initially researched and marketed as an antidepressant, bupropion was subsequently found to be effective as a smoking cessation aid. In 2006 it was the fourth-most prescribed antidepressant in the United States retail market, with more than 21 million prescriptions.

Gas chromatography is an important type of chromatography used in chemical analysis. A volatile substance or mixture is injected and carried down a column (the coil shown) to a detector, which records the amount and the time on the column for each component. An oven (shown here with the door open) maintains the column at a desired temperature.

History and Philosophy of Chemistry

Antoine Lavoisier

Many chemists have an interest in the history of chemistry. Those with philosophical interests will be interested that the philosophy of chemistry has quite recently developed along a path somewhat different from the general philosophy of science.

Selected biography

Harold Urey
Harold Urey (1893-1981) was an American physical chemist, who won the 1934 Nobel Prize in Chemistry for his work on isotopes, specifically the discovery of deuterium, a hydrogen isotope, and the production of heavy water. He also performed pioneering research in cosmochemistry, which studies the origin and development of elements and their isotopes, primarily within the solar system. Urey, along with his student Stanley Miller, may be best remembered for the renowned Miller-Urey experiment, which shows that a mixture of ammonia, methane and hydrogen, when exposed to ultraviolet radiation and water, can interact to form amino acids, the "building blocks" of terrestrial life. This experiment followed on from Urey's work on the oxygen isotope 18O, and is considered to be pioneering work in the field of paleoclimatology, as it attempts to explain the composition of the early Earth's atmosphere.
