The effect of current density on the structure of nickel electrolytic foams and their catalytic properties during hydrogen production

Конденсированные среды и межфазные границы, 2023
The effect of current density on the regularities of nickel foam deposition processes has been studied. Porous nickel foams were obtained by electrochemical deposition in the galvanostatic mode at current densities of 0.3, 0.6, 0.9, and 1.2 A cm-2.

Kinetics deformation of current-voltage characteristics of the varistor oxide structures due to overcharging of the localized states

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2014
Prolonged exposure of zinc oxide varistors to the electrical load leads to current-voltage characteristics (CVC) deformation, which is associated with a change in the height and width of the intergranular barriers, which are the main structural element ...

Shifts in Phytoplankton Community Structure Across an Anticyclonic Eddy Revealed From High Spectral Resolution Lidar Scattering Measurements

Frontiers in Marine Science, 2020
Changes in airborne high spectral resolution lidar (HSRL) measurements of scattering, depolarization, and attenuation coincided with a shift in phytoplankton community composition across an anticyclonic eddy in the North Atlantic. We normalized the total

The effect of relative humidity on the polarization Mueller matrix under the oil smoke environment

Frontiers in Physics, 2023
For the variation of the polarized Mueller matrix of oil smoke particles under different relative humidity levels, the polarized single scattering characteristics of oil smoke particles are studied by using the Mie scattering theory, and the multiple ...

How College Students Can Depolarize: Evidence for Political Moderation Within Homogeneous Groups

Michigan Journal of Community Service Learning, 2023
This paper demonstrates that, after deliberation, college students showed immense moderation potential and affective depolarization, especially even given their homogeneity as a bloc within American politics and within the overwhelmingly liberal sample ...

The role of action potential changes in depolarization-induced failure of excitation contraction coupling in mouse skeletal muscle

eLife, 2022
Excitation-contraction coupling (ECC) is the process by which electrical excitation of muscle is converted into force generation. Depolarization of skeletal muscle resting potential contributes to failure of ECC in diseases such as periodic paralysis ...

Modulation of Depolarization for Optical Data Links

IEEE Photonics Journal, 2022
Controlled depolarization of a polychromatic carrier can be applied simultaneously with polarization-shift keying (PolSK) to achieve a three-dimensional symbol space using only a direct-detection Stokes-vector receiver.
