Nanocubes are anything but child’s play. Weizmann Institute scientists have used them to create surprisingly yarn-like strands: They showed that given the right conditions, cube-shaped nanoparticles are able to align into winding helical structures.

Speed Limit Set For Fastest Electrical Switch

Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral.

First Biological Evidence Of Ancient Supernova

However, in 2004 scientists unexpectedly found an ancient iron radioisotope in the Earth’s crust along the ocean’s floor. Geological dating indicates that the iron had been embedded for about 2.2 million years.

Chiton Teeth Inspire Solar Cell, Lithium-ion Improvements

There are a number of iron oxides: Iron oxides Iron(II) oxide or ferrous oxide (FeO) The black-coloured powder in particular can cause explosions as it readily ignites. Iron(III) oxide or ferric oxide (Fe2O3) known in its natural state as hematite or haematite, but also purified for use as a coating in magnetic audio and computer media, where it is known as ferric oxide. Also known as rouge. Iron(II,III) oxide or ferrous ferric oxide (Fe3O4), better known as the black-coloured...

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...
