Title:
Biased transportations in a spatially asymmetric system at the nano-scale under thermal noise

Authors:
Wan, RZ; Fang, HP

Author Full Names:
Wan RongZheng; Fang HaiPing

Source:
SCIENCE CHINA-PHYSICS MECHANICS & ASTRONOMY 53 (8): 1565-1567 AUG 2010

Language:
English

Document Type:
Article

Author Keywords:
ratchet effect; nano-scale; thermal noise

KeyWords Plus:
WATER; CONDUCTION; CHANNEL

Abstract:
Under the theory of ratchet effect for meso- and macro-scale systems, the additional perturbation with a long time correlation and the breaking of spatial inversion symmetry are two main ingredients to bring unidirected transportations. With the help of a simple model system, we show that a spatially asymmetric system of the nano-scale length may induce biased transportations under thermal noise.

Title:
Electrokinetics at Aqueous Interfaces without Mobile Charges

Authors:
Bonthuis, DJ; Horinek, D; Bocquet, L; Netz, RR

Author Full Names:

Abstract:
We theoretically consider the possibility of using electric fields in aqueous channels of cylindrical and planar geometry to induce transport in the absence of mobile ionic charges. Using the Navier-Stokes equation, generalized to include the effects of water spinning, dipole orientation and relaxation, we show analytically that pumping of a dipolar liquid through an uncharged hydrophobic channel can be achieved by injecting torque into the liquid, based on the coupling between molecular spinning and fluid vorticity. This is possible using rotating electric fields and suitably chosen interfacial boundary conditions or transiently by suddenly switching on a homogeneous electric field. A static electric field, however, does not induce a steady state flow in channels, irrespective of the geometry. Using molecular dynamics (MD) simulations, we confirm that static fields do not lead to any pumping, in contrast to earlier publications. The pumping observed in MD simulations of car!
bon nanotubes and oil droplets in a static electric field is tracked down to an imprudent implementation of Leonard-Jones interaction truncation schemes.
