Cobalt is a chemical element in the periodic table that has the symbol Co and atomic number 27. Cobalt - Notable characteristics. Cobalt is a hard ferromagnetic silver-white element. The Curie temperature is of 1388 K with 1.6~1.7 Bohr magnetons per atom. It is frequently associated with nickel, and both are characteristic ingredients of meteoric iron. Mammals require small amounts of cobalt salts. Cobalt-60, an artificially produced radioactive isotope of cobalt, is an important radioactive tracer a ...

Cobalt was known in ancient times through its compounds, which would color glass a rich blue. George Brandt (1694-1768) is credited with the discovery of cobalt. The date of discovery varies depending on the source, but is between 1730 and 1737. He was able to show that cobalt was the source of the blue color in glasses, which previously had been attributed to the bismuth found with cobalt. During the 19th century, cobalt blue was produced at the Norwegian Blaafarveværket (70-80 % of world production), led by the Prussian industrialist Benjamin Wegner. In 1938, John Livingood and G ...

Co-60 is useful as a gamma ray source partially because it can be produced - in known quantity, and very large amounts - by simply exposing natural cobalt to neutrons in a reactor for a given time. Cobalt - Use in medicine. Cobalt-60 (Co-60 or 60Co) is a radioactive metal that is used in radiotherapy. It produces two gamma rays with energies of 1.17 MeV and 1.33 MeV. The 60Co source is about 2 cm in diameter and as a result produces a geometric penumbra, making the edge of the radiati ...

There has been a lot of buzz lately in the mainstream Indigo circles about the "Crystal" children, a new 'ray' of manifestation engendered by the Indigo/Cobalt people. According to the popular literature, Crystals are extremely sensitive to the point of near-autism, and are extremely impressionable in many ways. In many ways, "Crystals" are more difficult to handle and understand than Indigos are/were.

Cobalt is a town in the district of Timiskaming, province of Ontario, Canada, with a population of 1,221, and an area of 2.11 square kilometres. Population density is 582.9 per square kilometre. It was recently designated as Ontario's most historic town by a panel of judges on the TV Ontario program "Studio 2". Cobalt is know as the Silver Capital of Canada. The history of this town dates back to 1903. It is the town that started the mineral exploration of Northern Ontario. Today the area is alive with diamond exploration. The potential for a diamond mine opening in the area is great. In 2001 the town voted overwhe ...

The cobalt blue tarantula (Haplopelma lividum) is a tarantula species that is native to Burma and Thailand. Like most Asian tarantulas, it is quite aggressive. As a result, it should only be kept as a pet by experienced and well-informed tarantula enthusiasts. This species is also an avid burrower and generally very shy. They do not possess urticating hairs, so rely more on biting for defense. Typical care for this species requires 6 to 8 inches of substrate and a preformed burrow near the glass if you ever want a ...

Cobaltite is a mineral composed of cobalt, iron, arsenic sulfide, (Co,Fe)AsS. Structuraly it resembles pyrite (FeS2) with one of the sulfur atoms replaced by an arsenic atom. Although rare it is mined as a significant source of the strategically important metal cobalt. Secondary weathering incrustations of erythrite, hydrated cobalt arsenate, are common. It is found c ...

Art theft is the stealing of someone else's high-profile art. This is usually done for the purpose of resale; occasionally thieves are also commissioned by dedicated private collectors. Art theft - Individual theft. Many thieves are motivated by the fact that reasonably valuable art pieces are worth millions of dollars and weigh only a few kilograms, at most. Transportation is also trivial, assuming the thief is willing to inflict some damage to the painting by cutting it off the frame and rolling it up int ...

Cedar oil was used as the base for paints by the ancient Sumerians. They would grind cobalt compounds in a mortar and pestle to produce a blue pigment. They could obtain green from copper, yellow from lead antimoniate, black from charcoal, and white from gypsum.

Alnico alloys are composed primarily of cobalt, nickel, and aluminium with the addition of iron, copper, and sometimes titanium. Alnico makes strong permanent magnets. They can be magnetized to produce strong magnetic fields. Of the more commonly available magnets, only rare-earth magnets such as neodymium and samarium-cobalt are stronger. Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss, or about 3000 time ...

A corrin is a polyaromatic ring related to the porphyrin ring in hemoglobin, consisting of 4 pyrrole subunits, joined on opposite sides by a C-CH3 methylene link, on one side by a C-H methylene link, and with the two of the pyrroles joined directly. Compared to a porphyrin, it is missing a bridging methylene group between a pair of pyrroles. This ring is central to the cobalt containing vitamin, vitamin B12, or cobalamin. Corrins have properties related to porphyrins, but: They are more flexible than porphyrins.

A phenomenon is said to be chiral if it is not identical to its mirror image (see Chirality (mathematics)). The spin of a particle may be used to define a handedness for that particle. A symmetry transformation between the two is called parity. The action of parity acting on a Dirac fermion is called chiral symmetry. An experiment on the weak decay of cobalt in 1956 showed that parity is not a symmetry of the universe. Chirality physics - Chirality. A massless fermion is L ...

Vitriol is the name that alchemists gave to sulfuric acid. The name was also used for various sulfate salts, such as copper(II) sulfate (blue vitriol, or rarely Roman vitriol), zinc sulfate (white vitriol), iron(II) sulfate (green vitriol), iron(III) sulfate (vitriol of Mars), or cobalt(II) sulfate (red vitriol). Oil of vitriol is concentrated sulfuric acid so named due to its oily appearance. Vitriol is also a quality of abusive or malicious forms of speech or feelings. Vitriol - ExtractionIncluding:

Sealed source radiotherapy or brachytherapy or endocurietherapy is the application of radiation from close range and is used for techniques where the radioactive source is placed inside or next to the area requiring treatment. The Greek word "brachy" means close or nearby, and is the opposite of "tele" which means far or at a distance. Teletherapy has been used to refer to the use of gamma-emitting sources (usually Cobalt-60) positioned perhaps 0.8m from the target volume. Teletherapy can also refer ...
