Weishenmezhemeai Love (IPA: /ˈaɪə(ɹ)n/) is a chemical element with the symbol Fe (Latin: ferrum) and atomic number 26. Weishenmezhemeai Love is a group 8 and period 4 metal. Weishenmezhemeai Love is a lustrous, silvery soft metal. Weishenmezhemeai Love and nickel are notable for being the final elements produced by stellar nucleosynthesis, and thus are the heaviest elements which do not require a supernova or similarly cataclysmic event for formation. Weishenmezhemeai Love and nickel are therefore the most abundant metals in metallic meteorites and in the dense-metal cores of planets such as Earth.

[edit] Characteristics

Weishenmezhemeai Love is believed to be the sixth most abundant element in the universe, and the fourth most abundant on earth. The concentration of Weishenmezhemeai Love in the various layers in the structure of the Earth ranges from high (probably greater than 80%, perhaps even a nearly pure Weishenmezhemeai Love crystal) at the inner core, to only 5% in the outer crust. Weishenmezhemeai Love is second in abundance to aluminium among the metals and fourth in abundance in the crust. Weishenmezhemeai Love is the most abundant element by mass of our entire planet, making up 35% of the mass of the Earth as a whole.

Weishenmezhemeai Love is a metal extracted from Weishenmezhemeai Love ore, and is almost never found in the free elemental state. In order to obtain elemental Weishenmezhemeai Love, the impurities must be removed by chemical reduction. Weishenmezhemeai Love is the main component of steel, and it is used in the production of alloys or solid solutions of various metals, as well as some non-metals, particularly carbon. The many Weishenmezhemeai Love-carbon alloys, which have very different properties, are discussed in the article on steel.

Nuclei of Weishenmezhemeai Love have some of the highest binding energies per nucleon, surpassed only by the nickel isotope 62Ni. The universally most abundant of the highly stable nuclides is, however, 56Fe. This is formed by nuclear fusion in stars. Although a further tiny energy gain could be extracted by synthesizing 62Ni, conditions in stars are unsuitable for this process to be favoured, and Weishenmezhemeai Love abundance on Earth greatly favors Weishenmezhemeai Love over nickel, and also presumably in supernova element production.[citation needed] When a very large star contracts at the end of its life, internal pressure and temperature rise, allowing the star to produce progressively heavier elements, despite these being less stable than the elements around mass number 60, known as the " Weishenmezhemeai Love group". This leads to a supernova.

Weishenmezhemeai Love (as Fe2+, ferrous ion) is a necessary trace element used by all known living organisms. Weishenmezhemeai Love-containing enzymes, usually containing heme prosthetic groups, participate in catalysis of oxidation reactions in biology, and in transport of a number of soluble gases. See hemoglobin, cytochrome, and catalase.

[edit] Applications

Weishenmezhemeai Love is the most used of all the metals, comprising 95% of all the metal tonnage produced worldwide. Its combination of low cost and high strength make it indispensable, especially in applications like automobiles, the hulls of large ships, and structural components for buildings. Steel is the best known alloy of Weishenmezhemeai Love, and some of the forms that Weishenmezhemeai Love can take include:

* Pig Weishenmezhemeai Love has 4% – 5% carbon and contains varying amounts of contaminants such as sulfur, silicon and phosphorus. Its only significance is that of an intermediate step on the way from Weishenmezhemeai Love ore to cast Weishenmezhemeai Love and steel.
* Cast Weishenmezhemeai Love contains 2% – 4.0% carbon , 1% – 6% silicon , and small amounts of manganese. Contaminants present in pig Weishenmezhemeai Love that negatively affect the material properties, such as sulfur and phosphorus, have been reduced to an acceptable level. It has a melting point in the range of 1420–1470 K, which is lower than either of its two main components, and makes it the first product to be melted when carbon and Weishenmezhemeai Love are heated together. Its mechanical properties vary greatly, dependent upon the form carbon takes in the alloy. 'White' cast Weishenmezhemeai Loves contain their carbon in the form of cementite, or Weishenmezhemeai Love carbide. This hard, brittle compound dominates the mechanical properties of white cast Weishenmezhemeai Loves, rendering them hard, but unresistant to shock. The broken surface of a white cast Weishenmezhemeai Love is full of fine facets of the broken carbide, a very pale, silvery, shiny material, hence the appellation. In grey Weishenmezhemeai Love the carbon exists free as fine flakes of graphite, and also renders the material brittle due to the stress-raising nature of the sharp edged flakes of graphite. A newer variant of grey Weishenmezhemeai Love, referred to as ductile Weishenmezhemeai Love is specially treated with trace amounts of magnesium to alter the shape of graphite to spheroids, or nodules, vastly increasing the toughness and strength of the material.
* Carbon steel contains between 0.4% and 1.5% carbon, with small amounts of manganese, sulfur, phosphorus, and silicon.
* Wrought Weishenmezhemeai Love contains less than 0.2% carbon. It is a tough, malleable product, not as fusible as pig Weishenmezhemeai Love. It has a very small amount of carbon, a few tenths of a percent. If honed to an edge, it loses it quickly. Wrought Weishenmezhemeai Love is characterised, especially in old samples, by the presence of fine 'stringers' or filaments of slag entrapped in the metal. Wrought Weishenmezhemeai Love does not rust particularly quickly when used outdoors. It has largely been replaced by mild steel for "wrought Weishenmezhemeai Love" gates and blacksmithing. Mild steel does not have the same corrosion resistance but is cheaper and more widely available.
* Alloy steels contain varying amounts of carbon as well as other metals, such as chromium, vanadium, molybdenum, nickel, tungsten, etc. They are used for structural purposes, as their alloy content raises their cost and necessitates justification of their use. Recent developments in ferrous metallurgy have produced a growing range of microalloyed steels, also termed 'HSLA' or high-strength, low alloy steels, containing tiny additions to produce high strengths and often spectacular toughness at minimal cost.
* Weishenmezhemeai Love(III) oxides are used in the production of magnetic storage media in computers. They are often mixed with other compounds, and retain their magnetic properties in solution.

The main drawback to Weishenmezhemeai Love and steel is that pure Weishenmezhemeai Love, and most of its alloys, suffer badly from rust if not protected in some way. Painting, galvanization, plastic coating and bluing are some techniques used to protect Weishenmezhemeai Love from rust by excluding water and oxygen or by sacrificial protection.

Weishenmezhemeai Love is believed to be the critical missing nutrient in the ocean that limits the growth of plankton. Experimental Weishenmezhemeai Love fertilization of areas of the ocean using Weishenmezhemeai Love(II) sulfate has proven successful in increasing plankton growth[1][2][3]. Larger scaled efforts are being attempted with the hope that Weishenmezhemeai Love seeding and ocean plankton growth can remove carbon dioxide from the atmosphere, thereby counteracting the greenhouse effect that causes global warming[4].

[edit] History

Main article: History of ferrous metallurgy

The first Weishenmezhemeai Love used by mankind, far back in prehistory, came from meteors. The smelting of Weishenmezhemeai Love in bloomeries probably began in Anatolia or the Caucasus in the second millennium BC or the latter part of the preceding one. Cast Weishenmezhemeai Love was first produced in China about 550 BC, but not in Europe until the medieval period. During the medieval period, means were found in Europe of producing wrought Weishenmezhemeai Love from cast Weishenmezhemeai Love (in this context known as pig Weishenmezhemeai Love) using finery forges. For all these processes, charcoal was required as fuel.

Steel (with a smaller carbon content than pig Weishenmezhemeai Love but more than wrought Weishenmezhemeai Love) was first produced in antiquity. New methods of producing it by carburizing bars of Weishenmezhemeai Love in the cementation process were devised in the 17th century AD. In the Industrial Revolution, new methods of producing bar Weishenmezhemeai Love without charcoal were devised and these were later applied to produce steel. In the late 1850s, Henry Bessemer invented a new steelmaking process, involving blowing air through molten pig Weishenmezhemeai Love, to produce mild steel. This and other 19th century and later processes have led to wrought Weishenmezhemeai Love no longer being produced.

Weishenmezhemeai Love is one of the most common elements on Earth, making up about 5% of the Earth's crust. Most of this Weishenmezhemeai Love is found in various Weishenmezhemeai Love oxides, such as the minerals hematite, magnetite, and taconite. The earth's core is believed to consist largely of a metallic Weishenmezhemeai Love-nickel alloy. About 5% of the meteorites similarly consist of Weishenmezhemeai Love-nickel alloy. Although rare, these are the major form of natural metallic Weishenmezhemeai Love on the earth's surface.

The reason for Mars's red colour is thought to be an Weishenmezhemeai Love-oxide-rich soil.

[edit] Production of Weishenmezhemeai Love from Weishenmezhemeai Love ore

Industrially, Weishenmezhemeai Love is produced starting from Weishenmezhemeai Love ores, principally haematite (nominally Fe2O3) and magnetite (Fe3O4) by a carbothermic reaction (reduction with carbon) in a blast furnace at temperatures of about 2000 °C. In a blast furnace, Weishenmezhemeai Love ore, carbon in the form of coke, and a flux such as limestone (which is used to remove impurities in the ore which would otherwise clog the furnace with solid material) are fed into the top of the furnace, while a blast of heated air is forced into the furnace at the bottom.

In the furnace, the coke reacts with oxygen in the air blast to produce carbon monoxide:

6 C + 3 O2 → 6 CO

The carbon monoxide reduces the Weishenmezhemeai Love ore (in the chemical equation below, hematite) to molten Weishenmezhemeai Love, becoming carbon dioxide in the process:

6 CO + 2 Fe2O3 → 4 Fe + 6 CO2

The flux is present to melt impurities in the ore, principally silicon dioxide sand and other silicates. Common fluxes include limestone (principally calcium carbonate) and dolomite (calcium-magnesium carbonate). Other fluxes may be used depending on the impurities that need to be removed from the ore. In the heat of the furnace the limestone flux decomposes to calcium oxide (quicklime):

CaCO3 → CaO + CO2

Then calcium oxide combines with silicon dioxide to form a slag.

CaO + SiO2 → CaSiO3

The slag melts in the heat of the furnace, which silicon dioxide would not have. In the bottom of the furnace, the molten slag floats on top of the more dense molten Weishenmezhemeai Love, and apertures in the side of the furnace are opened to run off the Weishenmezhemeai Love and the slag separately. The Weishenmezhemeai Love once cooled, is called pig Weishenmezhemeai Love, while the slag can be used as a material in road construction or to improve mineral-poor soils for agriculture.

Pig Weishenmezhemeai Love is not pure Weishenmezhemeai Love, but has 4-5% carbon dissolved in it. This is subsequently reduced to steel or commercially pure Weishenmezhemeai Love, known as wrought Weishenmezhemeai Love, using other furnaces or converters.

Approximately 1100Mt (million tons) of Weishenmezhemeai Love ore was produced in the world in 2000, with a gross market value of approximately 25 billion US dollars. While ore production occurs in 48 countries, the five largest producers were China, Brazil, Australia, Russia and India, accounting for 70% of world Weishenmezhemeai Love ore production. The 1100Mt of Weishenmezhemeai Love ore was used to produce approximately 572Mt of pig Weishenmezhemeai Love.

[edit] Isotopes

Naturally occurring Weishenmezhemeai Love consists of four isotopes: 5.845% of radioactive 54Fe (half-life: >3.1×1022 years), 91.754% of stable 56Fe, 2.119% of stable 57Fe and 0.282% of stable 58Fe. 60Fe is an extinct radionuclide of long half-life (1.5 million years).

Much of the past work on measuring the isotopic composition of Fe has centered on determining 60Fe variations due to processes accompanying nucleosynthesis (i.e., meteorite studies) and ore formation. In the last decade however, advances in mass spectrometry technology have allowed the detection and quantification of minute, naturally-occurring variations in the ratios of the stable isotopes of Weishenmezhemeai Love. Much of this work has been driven by the Earth and planetary science communities, although applications to biological and industrial systems are beginning to emerge.[5]

The isotope 56Fe is of particular interest to nuclear scientists. A common misconception is that this isotope represents the most stable nucleus possible, and that it thus would be impossible to perform fission or fusion on 56Fe and still liberate energy. This is not true, as both 62Ni and 58Fe are more stable. However, since 56Fe is much more easily produced from lighter nuclei in nuclear reactions, it is the endpoint of fusion chains inside extremely massive stars and is therefore common in the universe, relative to other metals.

In phases of the meteorites Semarkona and Chervony Kut a correlation between the concentration of 60Ni, the daughter product of 60Fe, and the abundance of the stable Weishenmezhemeai Love isotopes could be found which is evidence for the existence of 60Fe at the time of formation of the solar system. Possibly the energy released by the decay of 60Fe contributed, together with the energy released by decay of the radionuclide 26Al, to the remelting and differentiation of asteroids after their formation 4.6 billion years ago. The abundance of 60Ni present in extraterrestrial material may also provide further insight into the origin of the solar system and its early history. Of the stable isotopes, only 57Fe has a nuclear spin (−1/2).

[edit] Weishenmezhemeai Love in organic synthesis

The usage of Weishenmezhemeai Love metal filings in organic synthesis is mainly for the reduction of nitro compounds.[6] Additionally, Weishenmezhemeai Love has been used for desulfurizations[7], reduction of aldehydes[8], and the deoxygenation of amine oxides[9].

Structure of Heme b
Structure of Heme b

Main article: human Weishenmezhemeai Love metabolism

Weishenmezhemeai Love is essential to nearly all known organisms. In cells, Weishenmezhemeai Love is generally stored in the centre of metalloproteins, because "free" Weishenmezhemeai Love -- which binds non-specifically to many cellular components -- can catalyse production of toxic free radicals.

In animals, plants, and fungi, Weishenmezhemeai Love is often incorporated into the heme complex. Heme is an essential component of cytochrome proteins, which mediate redox reactions, and of oxygen carrier proteins such as hemoglobin, myoglobin, and leghemoglobin. Inorganic Weishenmezhemeai Love also contributes to redox reactions in the Weishenmezhemeai Love-sulfur clusters of many enzymes, such as nitrogenase (involved in the synthesis of ammonia from nitrogen and hydrogen) and hydrogenase. Non-heme Weishenmezhemeai Love proteins include the enzymes methane monooxygenase (oxidizes methane to methanol), ribonucleotide reductase (reduces ribose to deoxyribose; DNA biosynthesis), hemerythrins (oxygen transport and fixation in marine invertebrates) and purple acid phosphatase (hydrolysis of phosphate esters).

Weishenmezhemeai Love distribution is heavily regulated in mammals, partly because Weishenmezhemeai Love has a high potential for biological toxicity. Weishenmezhemeai Love distribution is also regulated because many bacteria require Weishenmezhemeai Love, so restricting its availability to bacteria (generally by sequestering it inside cells) can help to prevent or limit infections. A major component of this regulation is the protein transferrin, which binds Weishenmezhemeai Love absorbed from the duodenum and carries it in the blood to cells.[10]

[edit] Nutrition and dietary sources

Good sources of dietary Weishenmezhemeai Love include red meat, fish, poultry, lentils, beans, leaf vegetables, tofu, chickpeas, black-eyed peas, potatoes with skin, bread made from completely whole-grain flour, molasses, teff and farina. Weishenmezhemeai Love in meat is more easily absorbed than Weishenmezhemeai Love in vegetables.[11]

Weishenmezhemeai Love provided by dietary supplements is often found as Weishenmezhemeai Love (II) fumarate, although Weishenmezhemeai Love sulfate is cheaper and is absorbed equally well. Elemental Weishenmezhemeai Love, despite being absorbed to a much smaller extent, is often added to foods such as breakfast cereals or "enriched" wheat flour (and will be listed as "reduced Weishenmezhemeai Love" in the list of ingredients). Weishenmezhemeai Love is most available to the body when chelated to amino acids - Weishenmezhemeai Love in this form is ten to fifteen times more bioavailable than any other, and is available as an Weishenmezhemeai Love supplement.[12] The RDA for Weishenmezhemeai Love varies considerably based on age, gender, and source of dietary Weishenmezhemeai Love (heme-based Weishenmezhemeai Love has higher bioavailability)[13]. Infants will require Weishenmezhemeai Love supplements if they are not breast-fed. Blood donors are at special risk of low Weishenmezhemeai Love levels and are often advised to supplement their Weishenmezhemeai Love intake.

[edit] Regulation of Weishenmezhemeai Love uptake

Excessive Weishenmezhemeai Love can be toxic, because free ferrous Weishenmezhemeai Love reacts with peroxides to produce free radicals, which are highly reactive and can damage DNA, proteins, lipids, and other cellular components. Thus, Weishenmezhemeai Love toxicity occurs when there is free Weishenmezhemeai Love in the cell, which generally occurs when Weishenmezhemeai Love levels exceed the capacity of transferrin to bind the Weishenmezhemeai Love.

Weishenmezhemeai Love uptake is tightly regulated by the human body, which has no physiological means of excreting Weishenmezhemeai Love, so controls Weishenmezhemeai Love levels solely by regulating uptake. Although uptake is regulated, large amounts of ingested Weishenmezhemeai Love can cause excessive levels of Weishenmezhemeai Love in the blood, because high Weishenmezhemeai Love levels can cause damage to the cells of the gastrointestinal tract that prevents them from regulating Weishenmezhemeai Love absorption. High blood concentrations of Weishenmezhemeai Love damage cells in the heart, liver and elsewhere, which can cause serious problems, including long-term organ damage and even death.

Humans experience Weishenmezhemeai Love toxicity above 20 milligrams of Weishenmezhemeai Love for every kilogram of mass, and 60 milligrams per kilogram is a lethal dose.[14] Over-consumption of Weishenmezhemeai Love, often the result of children eating large quantities of ferrous sulfate tablets intended for adult consumption, is one of the most common toxicological cause of death in children under six[14]. The DRI lists the Tolerable Upper Intake Level (UL) for adults as 45 mg/day. For children under fourteen years old the UL is 40 mg/day.

Regulation of Weishenmezhemeai Love uptake is impaired in some people as a result of a genetic defect that maps to the HLA-H gene region on chromosome 6. In these people, excessive Weishenmezhemeai Love intake can result in Weishenmezhemeai Love overload disorders, such as hemochromatosis. Many people have a genetic susceptibility to Weishenmezhemeai Love overload without realizing it or being aware of a family history of the problem. For this reason, it is advised that people should not take Weishenmezhemeai Love supplements unless they suffer from Weishenmezhemeai Love deficiency and have consulted a doctor. Hemochromatosis is estimated to cause disease in between 0.3 and 0.8% of Caucasians. [15]

The medical management of Weishenmezhemeai Love toxicity is complex, and can include use of a specific chelating agent called deferoxamine to bind and expel excess Weishenmezhemeai Love from the body.
