Time-Fractional Approach to the Electrochemical Impedance: The Displacement Current

G. Barbero, L. R. Evangelista, E. K. Lenzi

We establish, in general terms, the conditions to be satisfied by a time-fractional approach formulation of the Poisson-Nernst-Planck model in order to guarantee that the total cur…

Nonlinear curvature elasticity of nematic liquid crystals

I. Lelidis, G. Barbero

The nonlinear elastic properties of nematic liquid crystals have acquired new interest with the recent experimental observation of bulk modulated nematic phases which are composed…

Fourth order nematic elasticity and modulated nematic phases: a poor man's approach

G. Barbero, I. Lelidis

We propose an extension of Frank-Oseen's elastic energy for bulk nematic liquid crystals which is based on the hypothesis that the fundamental deformations allowed in nematic liqui…

Unwinding of the twist-bend nematic structure under an external field

Rafael Soares Zola, Giovanni Barbero, Ioannis Lelids +2

The recently discovered twist-bend nematic phase, , is a non-uniform equilibrium nematic phase that presents a spontaneous bend with a precession of the nematic directo…

The Kramers-Kronig relations for usual and anomalous Poisson-Nernst-Planck models

Luiz Roberto Evangelista, Ervin Kaminski Lenzi, Giovanni Barbero

The consistency of the frequency response predicted by a class of electrochemical impedance expressions is analytically checked by invoking the Kramers-Kronig (KK) relations. These…

A Poisson-Boltzmann Description for the Double-Layer Capacitance of an Electolytic Cell

Roberta Rarumy Ribeiro de Almeida, Luiz Roberto Evangelista, Giovanni Barbero

A Poisson-Boltzmann approach is used to determine the double-layer integral and differential capacitances in a finite-length situation for an electrolytic cell. By means of simple…
