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...

A North Carolina State University scientist says he's created a technology to eliminate foul odors and air pollutants emitted by chicken rendering facilities. Assistant Professor Praveen Kolar said his inexpensive treatment significantly mitigates odors from poultry rendering operations. Such emissions are not currently regulated by the government, but the smell can be extremely disruptive to a facility's community, Kolar said. Kolar, working with University of Georgia Associate Professor...

U.S. and British scientists have determined nickel might be a useful isotopic marker to trace the origins of single cell organisms that produce methane. Our data suggest significant potential in nickel stable isotopes for identifying and quantifying methanogenesis on the early Earth, said Vyllinniskii Cameron, a recent Penn State graduate and now a post-doctoral fellow at the University of Bristol. Little is known about the actual timing of the evolution of methane producing organisms or...

Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist. They are potential cornerstones in future magnetic data storage and spintronic devices provided a simple and fast way can be found to turn their electric and magnetic properties on and off. In a promising new development, researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) working with a prototypical multiferroic have...

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
