Underpotential deposition

Best insight from top research papers

Underpotential deposition is a method of depositing thin films with atomic-level control. It involves the use of a first element to mediate the growth of a second material. The process occurs between a potential positive to the bulk deposition potential for the mediating element and a potential slightly greater than the bulk deposition potential of the material to be deposited. By cycling the applied voltage between these potentials, repeated desorption/adsorption of the mediating element can be used to precisely control film growth on a layer-by-layer basis .

How is potential vorticity defined?5 answersPotential vorticity is defined as a quantity that governs the behavior of fluid motion in various contexts. It is a fundamental concept in fluid dynamics, particularly in magnetohydrodynamics (MHD) and atmospheric flow. In MHD, potential vorticity is derived from an equation analogous to Ertel's theorem, which relates it to the gyro-frequency, E × B- and diamagnetic polarization densities, and particle density. In atmospheric flow, potential vorticity is used as a meridional coordinate along with potential temperature as the vertical coordinate. This allows the atmosphere to be divided into undulating tubes, where air moves without penetrating through the walls, under adiabatic and frictionless conditions. The concept of potential vorticity is essential for understanding transport barriers in magnetically confined plasmas and for decomposing atmospheric flows into balanced and unbalanced components.

What is an cell potential?5 answersCell potential is the measure of the potential difference between two half cells in an electrochemical cell. It is caused by the ability of electrons to flow from one half cell to the other cell. The value of the standard cell potential of a reaction is dependent on the half-cell reactions used to carry out that reaction. It is not a state function and is inversely proportional to the number of electrons exchanged between half-cells. A cell potential measurement device is used to measure the potential change arising from cell activities. It consists of working electrodes arranged two-dimensionally in a working region and reference electrodes provided outside the working region. A cell potential measurement apparatus uses a planar electrode with a matrix of microelectrodes for multi-point simultaneous measurement of potential change arising from cell activities. It also includes optical observation means, stimulation signal supply means, and signal processing means.
