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.

Microwaved nanoribbons may bolster oil and gas wells

Researchers combined nanoribbons with an oil-based thermoset polymer intended to make wells more stable and cut production costs. When cured in place with low-power microwaves emanating from the drill assembly, the composite would plug the microscopic fractures that allow drilling fluid to seep through and destabilize the walls.
