Find out how emissions regulations killed Mazda's three-rotor 20B Wankel rotary engine, just as it was getting started in the ...

Abstract: With their very rich static and dynamical properties, magnetic vortex dynamics excited by a spin polarized current represent not only a model system to study the physical mechanisms of spin ...

Abstract: In this study, we theoretically demonstrate vortex core dynamics in a vortex spin torque oscillator (VSTO) with a modified free layer, which has a smaller radius than the original free layer ...

A volcano can casually puff out perfect smoke rings into the sky. There is a simple science behind these rare volcanic vortex rings. Imagine a mighty volcano casually blowing flawless smoke rings into ...
