Electrical power generation by mechanically modulating electrical double layers

Decreasing effective nanofluidic filter size by modulating electrical double layers: separation enhancement in microfabricated nanofluidic filters.

Conventional methods for separating biomolecules are based on steric interactions between the biomolecules and randomly oriented gel fibers. The recently developed artificial molecular sieves also rely on steric interactions for separation. In this work, we present an experimental investigation of a method that can be used in these sieves to increase separation selectivity and resolution. This ...

Electrical Instabilities in Double Layers and Membranes

The effect of applied voltage V on local thickness fluctuations (LTF) in lipid bilayers is examined using the continuum model and accounting for non-locality of membrane elastic moduli. Ponderomotive forces, calculated from the linearized Poisson-Boltzmann equation, reduce LTF energy quadratically with V . Combined with a significant increase in the apex field gradient and perturbation of lipid...

Electrical Potential between Dissimilar Clay Double Layers

A model describing the electric double layers in clay-electrolyte systems containing particles with different surface charge densities was developed and used to calculate the film thickness of water present in a clay paste. The average water film thicknesses (-18/~) calculated by considering the clay to contain 9 groups of particles of different charge densities did not differ from those calcul...

Integrating Electrical Power Generation System

An inventing electrical power generation system is developed by integrating simultaneously solar energy, rains energy, wind energy, charged cloud energy, lightning energy, thunder energy which are assigned as nonconventional or renewable energy sources. All the natural wastage energies are used for production of electricity. Electrical power is accomplished with a minimum cost and pollution fre...
