Bacteria Plays Role In Formation Of Dolomite
2012-06-08 05:37:32

While scientists remain uncertain exactly how the mineral dolomite is formed, an international team of researchers say that they have discovered that the process can be facilitated by bacteria. According to a recent press release jointly issued Monday by the Cluster of Excellence "The Future Ocean" and GEOMAR | Helmholtz Centre for Ocean Research Kiel, the mineral is primarily formed in extreme ecosystems like lakes and lagoons with high salinity. The exact process behind dolomite's...

Detection procedures, acceptable limits for testing established by USP As part of its ongoing efforts to help ensure the quality of medicines, the U.S. Pharmacopeial Convention (USP) has announced two new standards related to elemental impurities: General Chapters <232> Elemental Impurities–Limits and <233> Elemental Impurities–Procedures. The new standards provide procedures for the detection of selected impurities in drug products based on modern analytical...

New Study May Hold Clue To Proving the Gaia Theory
2012-05-18 04:30:16

The Gaia Hypothesis proposes that the Earth is actually a giant living organism, and a University of Maryland (UMD) study might have found the key to unlocking this mystery, and this discovery could lead to an improved understanding of the climate and changes that occur within it. The key is sulfur, and researchers hope to find the relationships between the atmosphere, ocean organisms, and land, using sulfur in order to prove the Gaia Theory. The Gaia Theory was first introduced in the...

Sulphur And Iron Commonly Found In Old Shipwrecks
2012-05-16 08:47:46

Sulphur and iron compounds have been found in shipwrecks off the coast of Sweden and in the Baltic Sea, according to a new study. The group behind the results includes scientists from the University of Gothenburg and Stockholm University. The results were presented recently in the Journal of Archaeological Science. Scientists reported large quantities of sulphur and iron compounds in the salvaged 17th century warship Vasa a few years ago. This resulted in the development of sulphuric acid...

Hematite (AE) or haematite (BE) is the mineral form of Iron (III) oxide, (Fe2O3), one of several iron oxides. The ore sometimes contains slight amounts of titanium. When shaped into ornaments, it is often called black diamond. Hematite is a very common mineral, coloured black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include Bloodstone, Iron Rose, Kidney Ore, Martite, Paint Ore, Specularite (Specular Hematite), Rainbow Hematite...

There are a number of iron oxides: Iron oxides Iron(II) oxide or ferrous oxide (FeO) The black-coloured powder in particular can cause explosions as it readily ignites. Iron(III) oxide or ferric oxide (Fe2O3) known in its natural state as hematite or haematite, but also purified for use as a coating in magnetic audio and computer media, where it is known as ferric oxide. Also known as rouge. Iron(II,III) oxide or ferrous ferric oxide (Fe3O4), better known as the black-coloured...

Limonite Limonite is a ferric hydrate of varying composition, the generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as Limonite often contains a varying amount of oxide compared to hydroxide. Together with hematite, it is mined as ore for the production of iron. Limonite is heavy and yellowish-brown. It is not a true mineral, however, but a mixture of similar hydrated iron oxide minerals, mostly Goethite. Limonite forms mostly in or near...

Manganese is a chemical element in the periodic table that has the symbol Mn and atomic number 25. Notable characteristics Manganese is a gray-white metal, resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal is ferromagnetic only after special treatment. The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed. Mn2+ often competes with Mg2+ in...
