    Title: Theory of Electric Double Layer Dynamics at Blocking Electrode
    Author: Kant, Rama
    Contributor: Kant, Rama (pacrepositoryorg)
    Subject: Electrodes ; Impedance ; Boundary Conditions ; Electric Double Layer ; Crossovers ; Electrodes ; Electrode Polarization ; Capacitance
    Description: A phenomenological theory of electric double layer polarization of blocking electrode is presented solving modified Debye-Falkenhagen (MDF) equation for potential, under the impedance boundary condition. The dynamic impedance and capacitance are obtained in terms Debye screening length and frequency dependent polarization length. Two characteristic relaxation frequencies for compact layer and diffuse layer are identified. At frequencies less than Helmholtz layer relaxation frequency the EDL is perfectly blocking. At frequencies larger than the diffuse layer relaxation frequency the EDL behaves like a resistor. At crossover frequencies the electrode is polarized. Theoretical results agrees well with experimental capacitance dispersion data.

    Title: Curvature-Induced Anomalous Enhancement in the Work Function of Nanostructures
    Author: Kaur, Jasmin; Kant, Rama
    Subject: Chemistry
    Description: An analytical theory to estimate the electronic work function in curved geometries is formulated under Thomas–Fermi approximation. The work function is framed as the work against the electrostatic self-capacitive energy. The contribution of surface curvature is characterized by mean and Gaussian curvature (through multiple scattering expansion). The variation in work function of metal and semimetal nanostructures is shown as the consequence of surface radius of curvature comparable to electronic screening length. For ellipsoidal particles, the maximum value of work function is observed at the equator and poles for oblate and prolate particles, respectively, whereas triaxial ellipsoid shows nonuniform distribution of the work function over the surface. Similarly, theory predicts manifold increase in the work function for a particle with atomic scale roughness. Finally, the theory is validated with experimental data, and it is concluded that the work function of a nanoparticle can...

    Title: Shape- and size-dependent electronic capacitance in nanostructured materials
    Author: Singh, Maibam Birla; Kant, Rama
    Subject: Sciences (General) ; Mathematics;
    Description: The shape and size are the two important geometrical factors that affect the electronic screening in nano-materials. Here, we develop an analytical theory for electronic capacitance based on Thomas–Fermi screening in conjunction with 'multiple scattering method' for arbitrary-shaped nanostructures including electronic spillover correction. We relate the electronic capacitance of the material to the curvature correction expressed in terms of ratio of electronic screening length to principal radii of curvature. Electronic capacitance of various nanostructures is obtained showing geometrical shape- and size-dependent electronic screening in nanostructures that manifest important consequences in charge storage enhancement or reduction.
