Electric Field Driven Torque in ATP Synthase

FO-ATP synthase (FO) is a rotary motor that converts potential energy from ions, usually protons, moving from high- to low-potential sides of a membrane into torque and rotary motion. Here we propose a mechanism whereby electric fields emanating from the proton entry and exit channels act on asymmetric charge distributions in the c-ring, due to protonated and deprotonated sites, and drive it to...

Electric Field-induced Structural Rearrangements in Biomembranes

Structure and function of biological membranes are vitally dependent on the electric membrane polarization; prolonged depolarization of the plasma membrane causes cell death. The natural cross-membrane electric field affecting the protein/lipid dielectrics are on the order of 100 kVcm_ t. The inhomogeneous field originating from ionic groups and adsorbed small ions are of the same order of magn...

Electric-field induced pK-changes in bacteriorhodopsin.

Bacteriorhodopsin, the only protein of the purple membranes of halobacteria [ 11, acts as a light-driven proton pump, translocating protons from the inner to the outer side of the plasma membrane [2]. The lightinduced asymmetric proton distribution contributes to the membrane potential by up to lo-40 mV [3]. Assuming a membrane thickness of 50 A, this potential difference corresponds to an elec...

Purely electric-field-driven perpendicular magnetization reversal.

If achieved, magnetization reversal purely with an electric field has the potential to revolutionize the spintronic devices that currently utilize power-dissipating currents. However, all existing proposals involve the use of a magnetic field. Here we use phase-field simulations to study the piezoelectric and magnetoelectric responses in a three-dimensional multiferroic nanostructure consisting...

Dimensional crossover driven by an electric field.

We study the steady-state dynamics of the Hubbard model driven out of equilibrium by a constant electric field and coupled to a dissipative heat bath. For a very strong field, we find a dimensional reduction: the system behaves as an equilibrium Hubbard model in lower dimensions. We derive steady-state equations for the dynamical mean-field theory in the presence of dissipation. We discuss how ...
