Using the world's fastest light source -- specialized X-ray lasers -- scientists at the University of Colorado Boulder and the National Institute of Standards and Technology have revealed the secret inner life of magnets, a finding that could lead to faster and "smarter" computers. Using a light source that creates X-ray pulses only one quadrillionth of a second in duration, the Boulder team was able to observe how magnetism in nickel and iron atoms works, and they found that each metal...

How nickel-titanium nanometric-size particles change back to their memorized shape University of Constance physicists Daniel Mutter and Peter Nielaba have visualized changes in shape memory materials down to the nanometric scale in an article about to be published in EPJ B´. Metallic alloys can be stretched or compressed in such a way that they stay deformed once the strain on the material has been released. Only shape memory alloys, however, can return to their original shape...

Collaboration uses Lehigh's advanced electron microscopes to pinpoint phase transition Why does a solid metal that is engineered for ductility become brittle, often suddenly and with dramatic consequences, in the presence of certain liquid metal impurities? The phenomenon, known as liquid metal embrittlement, or LME, has baffled metallurgists for a century. Now, a team of ceramics researchers has shed light on LME by obtaining atomic-scale images of unprecedented resolution of the...

Cobalt is a chemical element in the periodic table that has the symbol Co and atomic number 27. 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...

Garnierite is a mineral composed of hydrous nickel silicates a member of the serpentine group with formula: (Ni,Mg)3Si2O5(OH). Népouite is a synonym. Garnierite is important as a source of nickel and is mined from laterite deposits which are formed by intense weathering and secondary enrichment of ultramafic igneous rocks.

Pentlandite is a iron-nickel sulfide, (Fe,Ni)9S8. Pentlandite usually has a Ni:Fe ratio of close to 1:1. It also contains minor cobalt. Pentlandite forms isometric crystals, but is normally found in massive granular aggregates. It is brittle with a hardness of 3.5 - 4 and specific gravity of 4.6 - 5.0 and is non-magnetic. It has a yellowish bronze color. Pentlandite is the chief ore of nickel. Typically associated with pyrrhotite, niccolite, biotite, millerite, pyrite, and chalcopyrite...

Platinum is a chemical element in the periodic table that has the symbol Pt and atomic number 78. A heavy, malleable, ductile, precious, gray-white transition metal, platinum is resistant to corrosion and occurs in some nickel and copper ores along with some native deposits. Platinum is used in jewelry, laboratory equipment, electrical contacts, dentistry, and anti-pollution devices in automobiles. Notable characteristics The metal is a beautiful silvery-white when pure, and malleable...
