Carbon nanotubes bound for electronics not only need to be as clean as possible to maximize their utility in next-generation nanoscale devices, but contact effects may limit how small a nano device can be.
Researchers have developed a quantum sensor that will be able to precisely measure the tiny magnetic fields we can expect to see in the next generation of hard discs. The sensor itself is just slightly larger than a nitrogen atom, with a synthetic diamond to act as a substrate.
Scientists have successfully demonstrated exciting findings on the realization of field-driven ultrafast photo electron emission, in a system capable of much higher phase synchronization than its photon-driven counterpart.
Researchers have published the first part of what they expect to be a database showing the kinetics involved in producing colloidal metal nanocrystals - which are suitable for catalytic, biomedical, photonic and electronic applications - through an autocatalytic mechanism.
Soft molecules deposited on metallic surfaces were driven using a scanning tunneling microscope (STM) without mechanically pulling or pushing them, but by inducing inelastic excitations with the tunneling current.
Just as magnets attract iron particles in sandpits, permanent magnetics only attract one type of ion in an electrochemical solution, constituting the basis of magnetically controlled electrochemical transistors.
