The point of zero charge is the pH value for which the net surface charge of adsorbent is equal to zero. This concept has been introduced by an increase of interest in the pH of the solution during adsorption experiments. [1] The reason is that the adsorption of some substances is very dependent on pH. The pzc value is determined by the ...
Reception. "Rollin' in My 5.0" was one of Ice's most popular songs in the early '90s following his mainstream success and To the Extreme. The song and music video were retired on most music channels and radios in 1992. "Rollin'" by Limp Bizkit pays tribute to this song, while Ice references it himself in his song "Cruisin in My 6'4", from his ...
Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
A cold cathode [1] is a cathode that is not electrically heated by a filament. [note 1] A cathode may be considered "cold" if it emits more electrons than can be supplied by thermionic emission alone. It is used in gas-discharge lamps, such as neon lamps, discharge tubes, and some types of vacuum tube. The other type of cathode is a hot cathode ...
Some multistep reactions can also have apparent negative activation energies. For example, the overall rate constant k for a two-step reaction A ⇌ B, B → C is given by k = k 2 K 1 , where k 2 is the rate constant of the rate-limiting slow second step and K 1 is the equilibrium constant of the rapid first step.

The mass-to-charge ratio ( m / Q) is a physical quantity relating the mass (quantity of matter) and the electric charge of a given particle, expressed in units of kilograms per coulomb (kg/C). It is most widely used in the electrodynamics of charged particles, e.g. in electron optics and ion optics .
