Self-organized angleworm-like and centipede-like patterns in ac-driven electroconvection of nematic liquid crystals [PDF]
Scientific ReportsWe report localized electroconvection (EC) discovered in nematic liquid crystals (NLC), which resembles life-like angleworms (AW) and centipedes (CP) in nature. In the presence or absence of superposed noise on an ac field, such localized EC patterns are

Manipulating conductivity and noise for transitioning between stochastic and inverse stochastic resonances in liquid–crystal electroconvection [PDF]
Scientific ReportsNoise can play a constructive role in nature and various engineering systems. Over the past four decades, noise-induced stochastic resonances (SRs) have been extensively documented, showing enhancement in system performance.

High Electron Charge Carrier Mobility in the Nematic Phase of a Roof-Shaped Nematogen with Optimum Molecular Biaxiality. [PDF]
Adv Sci (Weinh)Liquid Roofs. Biaxial roof‐shaped mesogens self‐assemble in a nematic phase of a broad temperature range exhibiting high TOF electron mobilities. These mesogens possess the almost optimum biaxial aspect ratio. The results from X‐ray, polarized optical microscopy, modeling, and TOF data agree with biaxiality of small domains and transient nematic phase ...

Electroconvective Instability in Water Electrolysis: An Evaluation of Electroconvective Patterns and Their Onset Features [PDF]
Physical Review Applied, 2021 In electrochemical systems, an understanding of the underlying transport processes is required to aid in their better design. This includes knowledge of possible near-electrode convective mixing that can enhance measured currents. Here, for a binary acidic electrolyte in contact with a platinum electrode, we provide evidence of electroconvective ...

Equilibrium Electroconvective Instability [PDF]
Physical Review Letters, 2015 Since its prediction 15 years ago, hydrodynamic instability in concentration polarization at a charge-selective interface has been attributed to nonequilibrium electro-osmosis related to the extended space charge which develops at the limiting current. This attribution had a double basis. On the one hand, it has been recognized that neither equilibrium

Electrical Circuit Modeling of Nanofluidic Systems
Advanced Physics Research, Volume 2, Issue 10, October 2023., 2023 This work addresses a central challenge faced by the nanofluidics community: upscaling the electrical properties of a single nanochannel. It is demonstrated that the electrical circuit of a nanochannel array is equivalent to a parallel circuit of mutually independent single‐channel systems. Abstract Nanofluidic systems exhibit transport characteristics
