Inside the gaiter, the lever pivots through a ratchet system. When you apply the handbrake, a spring-loaded pawl engages with the ratchet mechanism to hold the lever in place with tension on the ...

Any builder or mechanic will tell you there’s a difference between high-end low-quality ratchets. See which models rank among the best ratchet options.

For breakthroughs in catalysed non-equilibrium systems, particularly molecular ratchet mechanisms, that have provided fundamental insights into the dynamics of matter. A team of researchers from the ...

The ratchet mechanisms felt robust and secure, making tightening easy. Releasing the straps required a bit more effort compared to other high-end picks, but this didn’t detract from their ...

The DNA-nanoparticle motor uses the 'burnt-bridge' Brownian ratchet mechanism. In this type of movement, the motor is being propelled by the degradation (or 'burning') of the bonds (or 'bridges ...

DNA-nanoparticle motors, which convert chemical energy into mechanical motion using a "burnt-bridge" Brownian ratchet mechanism, have been optimized to approach the speed of natural motor proteins.
