Hydrogen atoms can induce magnetism in graphene and be used to create a uniform magnetic order across the 1-D material. That is the finding of researchers in Spain, France and Egypt, who also demonstrated that it is possible to atomically manipulate hydrogen atoms on graphene...
The vortex-like structures in grains of magnetite can reliably preserve magnetic information, remaining unaltered by temperature changes, thereby recording the history of the Earth's magnetic field. That is the latest finding of researchers in Germany and the UK, who used...
A special form of iron known as iron-60 – thought to be created in supernovae – has been found in moon rock. It provides further evidence that a relatively nearby massive star exploded about 2 million years ago, propelling its newly-created elements towards Earth...
Many batteries in laptops, electric cars and other rechargeable devices are made of lithium. Over time, lithium corrodes inside the battery. Instead of lithium, researchers have now used gold nanowires to store electricity, and have found...
Scientists believe 80 percent of the universe is made up of dark matter. What exactly constitutes dark matter? Scientists still aren't sure. A new study, published this week in the journal Physical Review Letters, grows the list of particles not found in dark matter.
