Magnesium oil Magnesium oil (also referred to as transdermal magnesium) is a mixture of Magnesium chloride in water. In reality it is not an oil. It is applied to the skin. The magnesium is absorbed through the skin and is claimed to have health benefits, such as for the treatment of magnesium deficiency, to relieve muscle pains and aches (especially headaches), and enhance to relaxation.

Magnesium chloride Magnesium chloride is the name for the chemical compound with the formula MgCl and its various hydrates MgCl(HO). These salts are typical ionic halides, being highly soluble in water. The hydrated magnesium chloride can be extracted from brine or sea water. In North America, magnesium chloride is produced primarily from Great Salt Lake brine. It is extracted in a similar process from the Dead Sea in the Jordan valley. Magnesium chloride, as the natural mineral bischofite, is also extracted (via solution mining) out of ancient seabeds; for example, the Zechstein seabed in northwest Europe. Some magnesium chloride is made from solar evaporation of seawater. Anhydrous magnesium chloride is the principal precursor to magnesium metal, which is produced on a large scale. Hydrated magnesium chloride is the form most readily available.

Croton oil Croton oil ("Crotonis oleum") is an oil prepared from the seeds of "Croton tiglium", a tree belonging to the order Euphorbiales and family Euphorbiaceae, and native or cultivated in India and the Malay Archipelago. Small doses taken internally cause diarrhea. Externally, the oil can cause irritation and swelling. Croton oil is used in some chemical peels, due to its caustic exfoliating effects it has on the skin. Used in conjunction with phenol solutions, it results in an intense reaction which leads to initial skin sloughing. Since croton oil is very irritating and painful, it is used in laboratory animals to study how pain works, pain-relieving and anti-inflammatory drugs, and immunology.

North American Plate The North American Plate is a tectonic plate covering most of North America, Greenland, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores. It extends eastward to the Mid-Atlantic Ridge and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. The interior of the main continental landmass includes an extensive granitic core called a craton. Along most of the edges of this craton are fragments of crustal material called terranes, accreted to the craton by tectonic actions over the long span of geologic time. It is thought that much of North America west of the Rocky Mountains is composed of such terranes.

Neodymium Neodymium is a chemical element with symbol Nd and atomic number 60. It is a soft silvery metal that tarnishes in air. Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach. It is present in significant quantities in the ore minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Although neodymium is classed as a rare earth, it is a fairly common element, no rarer than cobalt, nickel, and copper, and is widely distributed in the Earth's crust. Most of the world's commercial neodymium is mined in China.

Clinohumite Clinohumite is an uncommon member of the humite group, a magnesium silicate according to the chemical formula (Mg, Fe)(SiO)(F,OH). The formula can be thought of as four olivine (MgSiO), plus one brucite (Mg(OH)). Indeed, the mineral is essentially a hydrated olivine and occurs in altered ultramafic rocks and carbonatites. Most commonly found as tiny indistinct grains, large euhedral clinohumite crystals are sought by collectors and occasionally fashioned into bright, yellow-orange gemstones. Only two sources of gem-quality material are known: the Pamir Mountains of Tajikistan, and the Taymyr region of northern Siberia. It is one of two humite group minerals that have been cut into gems, the other being the much more common chondrodite.

Aluminium magnesium boride Aluminum magnesium boride or BAM is a chemical compound of aluminium, magnesium and boron. Whereas its nominal formula is AlMgB, the chemical composition is closer to AlMgB. It is a ceramic alloy that is highly resistive to wear and has a low coefficient of sliding friction, reaching a record value of 0.02 in lubricated AlMgB−TiB composites. First reported in 1970, BAM has an orthorhombic structure with four icosahedral B units per unit cell. This ultrahard material has a coefficient of thermal expansion comparable to that of other widely used materials such as steel and concrete.

Georgbarsanovite Georgbarsanovite is a very rare mineral of the eudialyte group, formerly known under unaccepted name as barsanovite, with formula Na(Mn,Sr,REE)CaFeZrNbSi(SiO)(SiO)OCl•HO. The original formula was extended to show the presence of cyclic silicate groups and domination of silicon at the M4 site. "REE", standing for rare earth elements, are dominated by cerium. Georgbarsanovite characterizes in dominance of manganese at the N4 site. It also differs from most other accepted group representatives in its colour. The mineral was found in nepheline pegmatite nearby Petrelius river, Khibiny massif, Kola Peninsula, Russia. It is named after Russian mineralogist Georg Barsanov.

SHINE Medical Technologies In 2009, the supply of molybdenum-99 (Mo-99), a precursor to technetium-99m used in more than 30 medical imaging procedures, fell short of demand due to maintenance idling of a pair of research reactors, one located in the Netherlands, forcing doctors to use more dangerous isotopes. By 2016, the largest global supplier of the isotope, a Canadian research reactor, was scheduled to go idle. In 2010, the National Nuclear Security Administration (NNSA), a part of the United States Department of Energy, began funding a number of method development ventures aimed at ensuring that shortages in the United States could be avoided as well as reducing the use of highly enriched uranium and with it lowering the risk of nuclear proliferation.
