Ununpentium was discovered in 2003 by a group of scientists working at the Joint Institute for Nuclear Research in Dubna, Russia, and Lawrence Livermore National Laboratory (LLNL), California. In 2015, the International Union of Pure and Applied Chemistry (IUPAC) recognized the discovery of the element, which was renamed moscovium, referring to Moscow Oblast in Russia.

Flerovium was created in 1998 by a group of scientists (Russian and American) working at the Joint Institute for Nuclear Research in Dubna, Russia. The element was named flerovium after George Flerov, a Russian nuclear physicist.
Alloy steels contain wide varieties of steels exceeding the composition limits of Mn, C, Mo, Si, Ni, Va, and B set for the carbon steels. They are designated by AISI four-digit numbers.
Copernicium was discovered on 9 February 1996 by a group of research scientists working at the Heavy Ion Research Laboratory in Darmstadt, Germany under the guidance of Sigurd Hofmann.

A master alloy is a combination of base metals such as copper, aluminum, or nickel, and one or two other elements of relatively higher percentage. It is a semi-finished product that is primarily manufactured for use as a raw material. Master alloys can be produced in many shapes.

Iodine was first discovered by Barnard Courtois, a French chemist in 1811 while extracting potassium and sodium from seaweed ash. When he accidentally added sulfuric acid, a violet colored cloud evolved from the mass.

Edwin McMillan and Philip H. Abelson first produced neptunium at the University of California in 1940. The scientists bombarded uranium-238 atoms with neutrons to chemically produce neptunium-239 having a half-life of 2.3 days.
