Treatment of Cyanide-Free Wastewater from Brass Electrodeposition with EDTA by Electrodialysis: Evaluation of Underlimiting and Overlimiting Operations

Membranes, 2020
Growing environmental concerns have led to the development of cleaner processes, such as the substitution of cyanide in electroplating industries and changes in the treatment of wastewaters.

Electroconvection in a Suspended Fluid Film: A Linear Stability Analysis

, 1996
A suspended fluid film with two free surfaces convects when a sufficiently large voltage is applied across it. We present a linear stability analysis for this system.

Ionic Diode Current Rectification in High Salt Media with Sulfonated Poly(oxy‐1,4‐phenylene‐oxy‐1,4‐phenylenecarbonyl‐1,4‐phenylene)

ChemElectroChem, Volume 11, Issue 19, October 1, 2024.
High‐salt conditions are challenging for desalination and selective ion removal via ionic diode mechanisms. Here, current rectification with ionic diodes based on SPEEK ionomer is demonstrated up to aqueous 2 M NaCl and attributed to a change in mechanism form concentration polarisation to interfacial polarisation effects.

Temporal Modulation of the Control Parameter in Electroconvection in the Nematic Liquid Crystal I52

, 2000
I report on the effects of a periodic modulation of the control parameter on electroconvection in the nematic liquid crystal I52. Without modulation, the primary bifurcation from the uniform state is a direct transition to a state of spatiotemporal chaos.

Unique ergodicity in stochastic electroconvection

Nonlinear Differential Equations and Applications NoDEA
AbstractWe consider a stochastic electroconvection model describing the nonlinear evolution of a surface charge density in a two-dimensional fluid with additive stochastic forcing. We prove the existence and uniqueness of solutions, we define the corresponding Markov semigroup, and we study its Feller properties.

Temporal response to harmonic driving in electroconvection

, 2011
The temporal evolution of the spatially periodic electroconvection (EC) patterns has been studied within the period of the driving ac voltage by monitoring the light intensity diffracted from the pattern.

Direct observation of twist mode in electroconvection in I52

, 2000
I report on the direct observation of a uniform twist mode of the director field in electroconvection in I52. Recent theoretical work suggests that such a uniform twist mode of the director field is responsible for a number of secondary bifurcations in ...
