Electro-osmosis of electrorheological fluids
Physical Review E, 2013Electrorheological fluids are suspensions that are characterized by a strong functional dependence of the constitutive behavior of the fluids on the electric field. In this work, we consider electro-osmosis of an electrorheological fluid through a channel where a transverse, nonuniform electric field is spontaneously induced due to the presence of an ...

Excess moisture in a building is a serious problem that affects the quality of life and the durability of construction. The usage of electro osmosis in historic buildings has longer data as it is the least destructive method for removing noxious moisture from masonries.

Memristive model of electro-osmosis in skin
Physical Review E, 2011We show that some of the nonlinear conductance properties of electro-osmosis in sweat-duct capillaries may be modeled by a memristive circuit. This includes both the observed phase shift and amplitude modulation of the electrical current response to a simple harmonic driving potential.

Comparative Experimental Study on Solar Electro-Osmosis and Conventional Electro-Osmosis
2018As an effective method for accelerating the consolidation of soft soils, electro-osmosis has not been widely used in practice because of its high electric energy consumption. With the development of renewable solar energy, the solar energy is applied to electro-osmosis method and this paper has proposed a new solar electro-osmosis technology.

Simultaneous measurements of minute electrical current and water flow through single living cells of Nitella translucens have shown that there is an electro-osmotic transport of the order of 100 moles of water per Faraday in the direction of the positive ion flow.

Chaotic Induced-Charge Electro-Osmosis
Physical Review Letters, 2014We present direct numerical simulations of the coupled Poisson-Nernst-Planck and Navier-Stokes equations for an electrolyte around a polarizable cylinder subject to an external electric field. For high fields, a novel chaotic flow phenomenon is discovered.

Electro-osmosis in chara and nitella cells
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1969Abstract There is evidence that current-induced volume flows which are normally considered to be electro-osmosis have two components: a true electro-osmotic component due to frictional interaction and local osmosis due to a transport number effect. Recent measurements of such components and other parameters for both cells and cell walls are used to ...

Chaotic micromixer utilizing electro-osmosis and induced charge electro-osmosis in eccentric annulus
Physics of Fluids, 2016Efficient mixing is of significant importance in numerous chemical and biomedical applications but difficult to realize rapidly in microgeometries due to the lack of turbulence. We propose to enhance mixing by introducing Lagrangian chaos through electro-osmosis (EO) or induced charge electro-osmosis (ICEO) in an eccentric annulus. The analysis reveals

Electro-osmosis in Frozen Soil
Nature, 1964WATER can be transported in unfrozen soil under an electrical gradient. This process, which is called electro-osmosis, is due to an excess of positive ions over negative ions in the water near a solid surface. The amount of water which can be transported by electro-osmosis is such that in some instances it has been used to stabilize soft clay ...

Summary The present paper shows that, from a practical point of view, the electro-osmotic transport of water may be assumed to be constant for all soils. The magnitude of the osmotic permeability was found to be ke=5 × 10−5 cm. per sec. for for 1 volt per cm.
