Lighting up spintronics with re-writeable circuits
Researchers at the University of California Berkeley (UCB) and the City College of New York (CCNY) have developed a way of controlling the spin of a nucleus that could one day allow us to make rewritable spintronics circuits with light.According to Professor Jeremy Reimer, UCB professor of chemical and biomolecular engineering and the study co-author, the major drawback of existing chips is their permanence: "Once the chip is printed, it can only be used one way," he said.
Graphene gives boost to Edison's Nickel-Iron battery
Graphene has been used to revive a rechargeable battery technology invented by Thomas Edison (yes, that Thomas Edison) more than 100 years ago in a collision of technologies that could prove very fruitful.Edison’s idea was that the batteries would power electric vehicles, but the largely technology fell out of use in the 1970s, because although it is very durable, the charge and discharge times are very slow.
Catching light in a graphene net
An international team of physicists led by US researcher Dmitri Basov, of the University of California, demonstrated that light can be caught and controlled within the two dimensional lattice of wonder-material graphene.Theory has suggested that long wavelength – infrared – photons could be caught and moved through graphene at much less than the velocity of light.
