Occurrence of plastic collapse under ratcheting due to gravity and seismic loading
Mechanical Engineering Journal, 2022 The most dominant failure mode of piping components under seismic loading is fatigue failure with ratcheting. While it was confirmed via the experimental tests in the past, the Primary stress limit is applied to seismic loading to prevent plastic ...

Experimental Spin Ratchet [PDF]
Science, 2010 Spin Control Controlling and manipulating the spin of an electron is a central requirement for applications in spintronics. Some of the challenges researchers are facing include efficient creation of spin currents, minimization of Joule heating, and extending the lifetime of electronic spins, which is especially important for ...

An Artificial Molecular Pump Powered by Light
Angewandte Chemie, EarlyView.A minimal rotaxane‐based supramolecular system functions as a light‐powered molecular pump, capturing macrocycles from solution and concentrating them within an intramolecular compartment. Repeated azobenzene photoisomerization modulates the binding and kinetic barriers of threading and shuttling, generating a photon‐driven energy ratchet that sustains

Experiments and DEM Simulations of Granular Ratcheting [PDF]
, 2017 In this work we studied the effect of cyclic loading on a granular packing by means of numerical simulations and experiments. A confined packing of glass beads was prepared and one of the walls was moved cyclically with a prescribed amplitude of the ...
