Calcium Channel Permeation: A Field in Flux [PDF]
The Journal of General Physiology, 1999 In 1955, Alan Hodgkin and Richard Keynes published a study whose intent was to answer a rather technical question, but whose result triggered the modern analysis of ion channel permeation ([Hodgkin and Keynes, 1955][1]). They aimed to determine whether the K+ fluxes in giant axons followed the “

Membranes, 2022 Fouling tends to cause a significant increase in hydraulic resistance, decreased permeate flux, or increased transmembrane pressure (TMP) when a process is operated under constant TMP or constant flux conditions.

Permeate Flux in Ultrafiltration Membrane: A Review
Journal of Applied Membrane Science & Technology, 2017 Membrane processes exist for most of the fluid separations encountered in industry. The most widely used is membrane ultrafiltration, pressure driven process which is capable of separating particles in the approximate size range of 0.001 to 0.1 μm. The design of membrane separation processes, like all other processes, requires quantitative expressions ...

Ultrafiltration to Increase the Consistency of Fruit Pulps: The Role of Permeate Flux
ChemEngineering, 2023 Ultrafiltration is a well-known operation, widely used in food processing, especially to concentrate selectively liquid compounds. However, so far, it has been mainly used to change concentration and/or clarify liquids with low viscosity. Ultrafiltration
