Nanotechnology makes holograms highly efficient, secure

Researchers have programmed polarization into compact holograms. These holograms use nanostructures that are sensitive to polarization (the direction in which light vibrates) to produce different images depending on the polarization of incident light.

Spin-currents at metal-oxide interfaces for magnetic memories

New research describes the observation of spin-to-charge current conversion by spin pumping from a ferromagnetic permalloy to a Cu/BiO interface. The metal/insulator interface makes it easier to control the spin-charge current conversion with an external electric field.
