The westward drift of the lithosphere: A tidal ratchet?

Sign Up to like & get
recommendations! Published in 2017 at "Geoscience frontiers"

DOI: 10.1016/j.gsf.2017.11.009

Abstract: Abstract Is the westerly rotation of the lithosphere an ephemeral accidental recent phenomenon or is it a stable process of Earth's geodynamics? The reason why the tidal drag has been questioned as the mechanism determining… read more here.

recommendations! Published in 2018 at "Physica E: Low-dimensional Systems and Nanostructures"

DOI: 10.1016/j.physe.2018.04.001

Abstract: Circular and linear magnetic quantum ratchet effects induced by alternating electric fields in the terahertz frequency range have been observed. The ratchet current shows 1/B-periodic oscillations with an amplitude, which is much larger than the… read more here.

DOI: 10.1021/jacs.1c01172

Abstract: We report a rotaxane-based information ratchet in which the macrocycle distribution is pumped away from equilibrium using a carbodiimide fuel. A carboxylate group on the axle, nonequidistant between two macrocycle binding sites, efficiently catalyzes the… read more here.

DOI: 10.1021/jacs.2c07633

Abstract: Autonomous chemically fueled molecular machines that function through information ratchet mechanisms underpin the nonequilibrium processes that sustain life. These biomolecular motors have evolved to be well-suited to the tasks they perform. Synthetic systems that function… read more here.

DOI: 10.1038/nmat5007

Abstract: Modern nanofabrication techniques have opened the possibility to create novel functional materials, whose properties transcend those of their constituent elements. In particular, tuning the magnetostatic interactions in geometrically frustrated arrangements of nanoelements called artificial spin… read more here.

DOI: 10.1073/pnas.2202527119

Abstract: Significance Some classes of biological motors like the Sec61 complex or the bacterial type IV pilus can achieve directional transport of biomolecules through nanopores, according to an out-of-equilibrium process called translocation ratchet, which biases thermal… read more here.

recommendations! Published in 2022 at "Physical review. E"

DOI: 10.1103/physreve.105.054131

Abstract: We model a class of discrete-time information ratchet with a finite tape and explore its thermodynamic consequence as a Maxwell demon. We found that, although it supports the operational regime of an engine or eraser,… read more here.

DOI: 10.1103/physreve.107.024130

Abstract: With the finite-tape autonomous information ratchet modeled by He et al. [Phys. Rev. E 105, 054131 (2022)2470-004510.1103/PhysRevE.105.054131], we recast the information processing second law, giving a tighter bound on the work extracted, in terms of the… read more here.

recommendations! Published in 2017 at "Entropy"

DOI: 10.3390/e19040119

Abstract: The stochastic model of the Feynman–Smoluchowski ratchet is proposed and solved using generalization of the Fick–Jacobs theory. The theory fully captures nonlinear response of the ratchet to the difference of heat bath temperatures. The ratchet… read more here.
