Researchers from the FOM Foundation and the University of Groningen have developed a technique to produce graphene bridges in the shape of a hammock. Through these bridges the researchers transmit spin currents based on the magnetic moment of electrons. The new technique is important for spintronics equipment, which use the spin current for information storage and transfer. The researchers published their results on 18 June 2012 online in Nano Letters.
Although the theoretical predictions are positive about the spin current in graphene, the experimental results have yet to meet these expectations. The freely hanging graphene bridges were, however, found to be superb conductors for spin current.

Scientists in Groningen and Madrid have managed to capture unique images of the first steps of virus assembly. By using a very fast scanning probe microscope, they were able to film how HIV proteins begin to form a virus. It appears that the virus...
Restanten van een vergeten bolhoop ontdekt rond de Melkweg
Een nieuw internationaal onderzoek laat zien dat bestanden van trekkende zoetwatervissen zoals zalm, paling en houting in de afgelopen vijftig jaar met 76% zijn afgenomen. In Europa is de afname met 93% het grootste. De trekvissen hebben het vooral...
