Outstanding supercapacitive properties of Mn-doped TiO2 micro/nanostructure porous film prepared by anodization method. [PDF]

open access: yes, 2016
Mn-doped TiO2 micro/nanostructure porous film was prepared by anodizing a Ti-Mn alloy. The film annealed at 300 °C yields the highest areal capacitance of 1451.3 mF/cm(2) at a current density of 3 mA/cm(2) when used as a high-performance supercapacitor ...

Charge storage in nanotubes: the case of a 2-1 electrolyte

open access: yesCondensed Matter Physics, 2017
We consider a 2-1 electrolyte in contact with a narrow nanotube, which only allows one-dimensional storage along the axis. The asymmetry does not allow an a priori definition of the potential of zero charge; instead, the natural reference is the ...

Axonal Computations

open access: yesFrontiers in Cellular Neuroscience, 2019
Axons functionally link the somato-dendritic compartment to synaptic terminals. Structurally and functionally diverse, they accomplish a central role in determining the delays and reliability with which neuronal ensembles communicate.

Correlation of EDLC Capacitance with Physical Properties of Polyethylene Terephthalate Added Pitch-Based Activated Carbon

open access: yesMolecules, 2022
The electric double-layer capacitor (EDLC) has attracted attention by using activated carbon (AC) as an active electrode material with a high power density and high cost-efficiency in industrial applications. The EDLC has been actively developed over the

Chemical capacitance proposed for manganite-based ceramics [PDF]

open access: yes, 2013
The measured value of effective electric permittivity \varepsilon_{eff} of several compounds, e.g., (BiNa)(MnNb)O_{3}, (BiPb)(MnNb)O_{3}, and BiMnO_{3} increases from a value \approx 10-100 at the low temperature range (100-300 K) up to the high value ...

Electrostatics of the nanowire radial p-i-n diode

open access: yesSemiconductor Physics, Quantum Electronics & Optoelectronics, 2019
In this paper, the electrostatic theory of the nanowire radial core-shell p-i-n homojunction has been considered. The carried out calculations show that, in contrast to planar p-i-n diode, the built-in electric field of the nanowire radial p-i-n diode ...

The Study of Ion Transport Parameters in MC-Based Electrolyte Membranes Using EIS and Their Applications for EDLC Devices

open access: yesMembranes, 2022
A solution cast technique was utilized to create a plasticized biopolymer-based electrolyte system. The system was prepared from methylcellulose (MC) polymer as the hosting material and potassium iodide (KI) salt as the ionic source.
