Researchers in Chicago and London have developed a method for controlling the properties of magnets that could be used to improve the storage capacity of next-generation computer hard drives. Magnets that can readily switch their polarity are widely used in the computer industry for data storage, but they present an engineering challenge: A magnet's polarity must be easily switched when writing data to memory, but be difficult to switch when storing or reading it. These conflicting...

LONDON, January 12 /PRNewswire/ -- - Roskill Information Services - Nickel: Market Outlook to 2014 (12th Edition, 2010) The fallout from the financial crisis that afflicted the world economy has seen nickel prices fluctuate wildly. LME prices peaked at just over US$52,000/t in May 2007, on the back of strong demand and low stocks, but had fallen by over 80% by the end of 2008, as demand collapsed. By the fourth quarter of 2009, however, prices had recovered to US$18,500/t....

Much of our planet's mineral wealth was deposited billions of years ago when Earth's chemical cycles were different from today's. Using geochemical clues from rocks nearly 3 billion years old, a group of scientists including Andrey Bekker and Doug Rumble from the Carnegie Institution have made the surprising discovery that the creation of economically important nickel ore deposits was linked to sulfur in the ancient oxygen-poor atmosphere. These ancient ores -- specifically iron-nickel...

SAN FRANCISCO, Oct. 27 /PRNewswire-USNewswire/ -- Ghosts and goblins aren't the only spooky things lurking around this Halloween. A new report by the Campaign for Safe Cosmetics reveals that popular children's face paints contain lead, a potent neurotoxin, as well as nickel, cobalt and chromium, which can cause lifelong skin sensitization and contact dermatitis. Creepier yet, these metals were not listed on any of the product labels, so parents have no way of knowing what children are...

Researchers of Eindhoven University of Technology and the Radboud University Nijmegen in The Netherlands show for the first time why ordinary graphite is a permanent magnet at room temperature. The results are promising for new applications in nanotechnology, such as sensors and detectors. In particular graphite could be a promising candidate for a biosensor material. The results will appear online on 4 October in Nature Physics. Graphite is a well-known lubricant and forms the basis for...

An international team of physicists has for the first time observed magnetic behavior in an atomic gas, addressing a decades-old debate as to whether it is possible for a gas or liquid to become ferromagnetic and exhibit magnetic properties. "Magnets are all around us "“ holding postcards on the refrigerator, pointing to magnetic north on a compass, and in speakers and headphones "“ yet some mysteries remain," says Joseph H. Thywissen, a professor of physics at the University of...

LONDON, September 16 /PRNewswire/ -- - Fifth International Conference on Rare Earths From Fox News to the The Times of London - everyone is talking about rare earths. For years these 15 elements with exotic names have been used in magnets, light bulbs, batteries, engineering ceramics and dozens of other applications. China has dominated production since the late 1990s but its share of consumption has also been growing and, to protect resources, export quotas and taxes have been...

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...

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...

Magnetite is a magnetic mineral form of both iron(II) oxide and iron(III) oxide or (iron(II,III) oxide), with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks as well as many sedimentary rocks. Magnetite is a...
