Electrokinetic phenomena are a family of several different effects that occur in heterogeneous fluids, or in porous bodies filled with fluid, or in a fast flow over a flat surface. The term heterogeneous here means a fluid containing particles.
In general, the phenomena relate to the direct conversion of electrical energy into kinetic energy, and vice versa. In the first instance, shaped electrostatic fields (ESF's) create hydrostatic pressure (HSP, or motion) in dielectric media. When such media are fluids, a flow is produced. If the dielectric is a vacuum or a solid, no flow is ...
Electrokinetics or electrokinetic may refer to: Electrohydrodynamics, the study of the dynamics of electrically charged fluids; Electrokinetic phenomena, a family of several different effects that occur in heterogeneous fluids; Zeta potential, a scientific term for electrokinetic potential
The streaming potential is also the primary electrokinetic phenomenon for the assessment of the zeta potential at the solid material-water interface. A corresponding solid sample is arranged in such a way to form a capillary flow channel. Materials with a flat surface are mounted as duplicate samples that are aligned as parallel plates.
Induced-charge electrokinetics in physics is the electrically driven fluid flow and particle motion in a liquid electrolyte. [2] Consider a metal particle (which is neutrally charged but electrically conducting) in contact with an aqueous solution in a chamber/channel.
AP Physics C: Mechanics and AP Physics 1 are both introductory college-level courses in mechanics, with the former recognized by more universities. [1] The AP Physics C: Mechanics exam includes a combination of conceptual questions, algebra-based questions, and calculus-based questions, while the AP Physics 1 exam includes only conceptual and algebra-based questions.
A streaming current and streaming potential are two interrelated electrokinetic phenomena studied in the areas of surface chemistry and electrochemistry. They are an electric current or potential which originates when an electrolyte is driven by a pressure gradient through a channel or porous plug with charged walls. [1] [2] [3]
AP Physics 1 is an algebra-based, introductory college-level physics course that includes mechanics topics such as motion, fluids, force, momentum, energy, harmonic motion, and rotation. The College Board published a curriculum framework that includes eight big ideas on which AP Physics 1 is based.
