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.
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.
This article illustrates the mechanism and regulation of hemostasis, provides information on nanoparticle action on hemostasis and describes concept and limitations of in vitro assays in the assessment of nanoparticles.
Physicists have succeeded in measuring the very weak van der Waals forces between individual atoms for the first time. To do this, they fixed individual noble gas atoms within a molecular network and determined the interactions with a single xenon atom that they had positioned at the tip of an atomic force microscope.
Inside a drop of paint, light is scattered so often that it seems impossible to demonstrate quantum effects. But despite the thousands of possible paths the light can take, like a drunk person inside a labyrinth, researchers now show that there are just two exits.
Scientists have demonstrated how a detailed picture of the electronic states can be ascertained by systematically comparing all of the interactive electronic processes in a simple system of aqueous iron(II).
