Scientists have proposed and experimentally demonstrated a ratchet concept to control the spin motion. In analogy to a ratchet wrench, which provides uniform rotation from oscillatory motion, such ...

Customization of rotary and linear motion systems improves performance, reduces costs and simplifies complex applications in manufacturing and medical devices. Advances in smart, compact and ...

Above: CAD model of the tunable oscillating and rotational kinematic damper. Wind is rapidly becoming a more prevalent source of energy around the world. Simultaneously, wind turbines are being ...

Torsional vibration is an oscillatory angular motion causing twisting in the shaft of a system; the oscillatory motion is superimposed on the steady rotational motion of a rotating/reciprocating ...

The Nature Index 2026 Research Leaders reveal the leading institutions and countries/territories in the natural sciences, health sciences, applied sciences and social sciences, according to their ...
