The current at the working electrode is plotted versus the voltage at the working electrode to yield the cyclic voltammogram (see Figure 1). Cyclic voltammetry is generally used to study the electrochemical properties of an analyte in solution [2] [3] [4] [1] or of a molecule that is adsorbed onto the electrode.
The ion vibration current (IVI) and the associated ion vibration potential is an electric signal that arises when an acoustic wave propagates through a homogeneous fluid. Historically, the IVI was the first known electroacoustic phenomenon. It was predicted by Peter Debye in 1933. [1]
Thus, TIMS devices do neither require large size nor high voltage in order to achieve high resolution, for instance achieving over 250 resolving power from a 4.7 cm device through the use of extended separation times. [25] However, the resolving power strongly depends on the ion mobility and decreases for more mobile ions.
Troubleshooting is a form of problem solving, often applied to repair failed products or processes on a machine or a system. It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again. Troubleshooting is needed to identify the symptoms.
The N-1 roots that are zero for = are called "slow modes", since can be comparable to or less than the thermal speed of one or more of the ion species. A case of interest to nuclear fusion is an equimolar mixture of deuterium and tritium ions ( f D = f T = 1 / 2 {\displaystyle f_{D}=f_{T}=1/2} ).
Structures for lossless ion manipulations (SLIM) are a form of ion optics to which various radio frequency and dc electric potentials can be applied and used to enable a broad range of ion manipulations, such as separations based upon ion mobility spectrometry, reactions (unimolecular, ion-molecule, and ion-ion), and storage (i.e. ion trapping).

The Bohnenberger electrometer, developed by J. G. F. von Bohnenberger from an invention by T. G. B. Behrens, [1] consists of a single gold leaf suspended vertically between the anode and cathode of a dry pile. Any charge imparted to the gold leaf causes it to move toward one or the other pole; thus, the sign of the charge as well as its ...
