Fractional Energy: A Theoretical Characterization of the State of Charge of the Ultracapacitor Modeled as a Constant Phase Element

Fractal and Fractional
Based on the Infinite State Representation (ISR) of the Riemann–Liouville integral, the energy stored in a fractional-order integrator is revisited, together with the energy dissipated through Joule losses.

Mesoporous PU/PEDOT:PSS Electrodes Reveal Population-Level Stochastic Bioelectrical Dynamics in Marine Diatoms. [PDF]

Adv Sci (Weinh)
Mesoporous mixed ionic‐electronic PU/PEDOT: PSS electrodes enable label‐free detection of stochastic extracellular bioelectrical dynamics in living Phaeodactylum tricornutum. Living diatoms actively modulate interfacial ionic dynamics, establishing stochastic electrochemical noise as a sensitive probe of microbial bioelectrochemical activity and a new ...

Contribution of Surface Distributions to Constant-Phase-Element (CPE) Behavior: 3. Adsorbed Intermediates [PDF]

Electrochimica Acta, 2017
Abstract The influence of surface distributions on rates of heterogeneous reactions coupled by adsorbed intermediates was studied to determine whether this form of surface heterogeneity can provide a physical explanation for constant-phase-element behavior.

Study of phase evolution and dielectric properties of Sr2Mn0.7Sn0.3O4 [PDF]

Processing and Application of Ceramics, 2023
Ruddlesden-Popper oxide Sr2Mn0.7Sn0.3O4 was synthesized by solid state method by calcining at different temperatures between 1200 and 1500°C. The phase evolution during thermal treatments was investigated and it was shown that the powder calcined at 1500°
