Lithium/solid polymer electrolyte (SPE)/sulfur cells were studied in operando by two techniques: Scanning Electron Microscope (SEM) and ultraviolet–visible absorption spectroscopy (UV–vis). During the operation of the cell, extensive polysulfide dissolution in the solid polymer electrolyte (cross-linked polyethylene oxide) leads to the formation of a catholyte.

Apr 07, 2004· The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system, that is, a measure of the system's overall polarity.The SI units for electric dipole moment are coulomb-meter (C⋅m); however, a commonly used unit in atomic physics and chemistry is the debye (D).. Theoretically, an electric dipole is defined by the first-order term of the ...

Personalized energy (PE) is a transformative idea that provides a new modality for the planet’s energy future. By providing solar energy to the individual, an energy supply becomes secure and available to people of both legacy and nonlegacy worlds and minimally contributes to an increase in the anthropogenic level of carbon dioxide. Because PE will be possible only if solar energy is ...

The microscopic process of the photoelectric effect is that an individual photon is absorbed by the metal and its energy is used to excite an electron. The electron will be emitted from the metal if the photon energy, where W is known as the “work function” and represents the minimal energy needed to liberate the electron from the metal. If,

Feedback control of a low-frequency azimuthal wave known as a "rotating spoke" in the ExB discharge of a cylindrical Hall thruster was demonstrated. The rotating spoke is an m=1 azimuthal variation in density, electron temperature, and potential that rotates at about 10% of the local E x B electron …

Atom - Atom - Discovery of radioactivity: Like Thomson’s discovery of the electron, the discovery of radioactivity in uranium by French physicist Henri Becquerel in 1896 forced scientists to radically change their ideas about atomic structure. Radioactivity demonstrated that the atom was neither indivisible nor immutable. Instead of serving merely as an inert matrix for electrons, the atom ...

Background: The most used score to measure comorbidity is the Charlson index. Its application to a health care administrative database including International Classification of Diseases, 10th edition (ICD-10) codes, medical procedures, and medication required studying its properties on survival. Our objectives were to adapt the Charlson comorbidity index to the French National Health Insurance ...

The aim of this paper is to confirm the existence of atmospheric pressure dielectric controlled glow discharge and to describe its main behavior. Electrical measurements, short time exposure photographs, and numerical modeling were used to achieve this task. Experimental observations and numerical simulation are in good agreement. Therefore, the analysis of the calculated space and time ...

This is a known property that can be inferred from the solution of the Boltzmann equation for electron transport and collisions [7]. Since λ = 1/Nσ, where σ is the mean electron cross section and N the gas density, εis proportional to E/N. Thus, the mean electron ...

That means, that at fixed gas pressure, plasma geometry, discharge power, and magnetic confinement, the plasma density, its spatial profile n(x,r), and electron temperature T e are the same for MWP, ICP, and HP. The difference is in the power losses in their antennas and matching networks, resulting in different power transfer efficiencies.

Nov 27, 2018· Depth of Discharge (DOD) Depth of Discharge (DOD) is the opposite of SOC. While SOC tells us how much percentage of charge is remaining, the DOD tells us how much percentage of charge is consumed in the battery.
