"We've developed a mechanism for digital memory storage that consists of a crystalline iron nanoparticle shuttle enclosed within the hollow of a multiwalled carbon nanotube," said project leader Alex Zettl.
Micro-miniature current generators are the subject of research being carried out at the University of Liverpool in partnership with a university in China
"This is an exciting discovery because it means we may one day be able to tailor-make a material from the bottom up, starting with the microstructure, so it ticks all the boxes required to run a magnetic fridge," says Professor Lesley Cohen.
It is anticipated that the research could one day lead to laser diode-based optical communictaions systems capable of supporting internet access technology with speeds up to 10Gbit/s
A US research team has written, read and erased polarised domains in a ferroelectric strontium titanate film on silicon.
For storing charge, US researchers have reported the highest known breakdown strength for bulk glass.
A US team claims to be on the way to non-volatile transistors with the production of thin-film ferroelectric strontium titanate.
Scientists at the University of Glasgow claim to have developed a diamond transistor with 50nm gate length - claimed to be the world's smallest.
"As the potential to apply the theory of quantum mechanics in practical applications such as computing and cryptography moves closer, the need for a high purity material becomes paramount," says Element Six.
The University of Southampton has been awarded £6m to establish a centre for nanostructured photonic metamaterials by the Engineering and Physical Sciences Research Council (EPSRC).
