If positive and negative charges are both present in equal amounts, then this is the isoelectric point. Thus, the PZC refers to the absence of any type of surface charge, while the IEP refers to a state of neutral net surface charge. The difference between the two, therefore, is the quantity of charged sites at the point of net zero charge.

Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [3]
Calculator is a basic calculator application made by Apple Inc. and bundled with its macOS, iOS, iPadOS, and watchOS operating systems. It has three modes: basic, scientific, and programmer. It has three modes: basic, scientific, and programmer.
The largest size of minivans is also referred to as "large MPV" and became popular following the introduction of the 1984 Renault Espace and Dodge Caravan. Since the 1990s, the smaller compact MPV and mini MPV sizes of minivans have also become popular. If the term "minivan" is used without specifying a size, it usually refers to a large MPV.
The investigation of short-lived radioactive nuclei (RI) by means of electron scattering has never been performed because of an inability to make these nuclei a target, [46] now with the advent of a novel self-confining RI technique at the world's first facility dedicated to the study of the structure of short-lived nuclei by electron ...
The unit is named after Blaise Pascal, noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer.The name pascal was adopted for the SI unit newton per square metre (N/m 2) by the 14th General Conference on Weights and Measures in 1971.
The current increases exponentially as the junction forward voltage is increased. The values given in the table are typical for a current of 1 mA (the same values apply to semiconductor diodes). The lower the junction forward voltage the better, as this means that less power is required to "drive" the transistor.
