81electrochemical reaction — ▪ chemistry Introduction any process either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances one a solid and the other a liquid. Under ordinary… …
82Differential pulse voltammetry — (AKA Differential Pulse Polarography or DPP) is often used to make electrochemical measurements. It can be considered as a derivative of linear sweep voltammetry or staircase voltammetry, with a series of regular voltage pulses superimposed on… …
83Copper indium gallium selenide solar cells — Copper indium gallium selenide (CuIn1 xGaxSe2 or CIGS) is a direct bandgap semiconductor useful for the manufacture of solar cells. Because the material strongly absorbs sunlight, a much thinner film is required than of other semiconductor… …
84Electroanalytical method — Electroanalytical methods are a class of techniques in analytical chemistry which study an analyte by measuring the potential (Volts) and/or current (Amps) in an electrochemical cell containing the analyte. [Bard, A.J.; Faulkner, L.R.… …
85Potentiometric sensor — A potentiometric sensor is a type of chemical sensor that may be used to determine the analytical concentration of some components of the analyte gas or solution. These sensors measure the electrical potential of an electrode when no current is… …
86Potentiometer (measuring instrument) — A potentiometer is an instrument for measuring the potential (voltage) in a circuit. Before the introduction of the moving coil and digital volt meters, potentiometers were used in measuring voltage, hence the meter part of their name. The method …
87Biosensor — A biosensor is a device for the detection of an analyte that combines a biological component with a physicochemical detector component. [GoldBookRef|title=biosensor|url=http://goldbook.iupac.org/B00663.html] It consists of 3 parts: * the… …
88PH — is the measure of the acidity or alkalinity of a solution. It is formally a measure of the activity of dissolved hydrogen ions (H+), but for very dilute solutions, the molarity (molar concentration) of H+ may be used as a substitute with little… …
89Neopolarogram — mathematical relation of current, charge and fractional derivatives. The term Neopolarogram refers to mathematical derivatives of polarograms or cyclic voltammograms that in effect deconvolute diffusion and electrochemical kinetics. This is… …
90Local field potential — A local field potential (LFP) is a particular class of electrophysiological signals, which is related to the sum of all dendritic synaptic activity within a volume of tissue. BackgroundA signal is recorded using a low impedance extracellular… …
