Ionic Transport Behavior of Soft Nanochannels for Newtonian and Non-Newtonian Electrolytes

“…In electroosmotic flow (EOF), fluid motion is induced by an external electric field applied tangentially to the surface, primarily due to the presence of an electrical double layer (EDL) near the surface . Given its versatility across various domains such as chemical and biological analysis, , electronic device, − drug delivery, − energy generation, − and separation processes, − EOF has attracted the attention of many researchers. Additionally, electroosmosis finds prominent applications in micro/nanofluidic systems for efficient fluid pumping while minimizing analyte diffusion. − …”

“…Das and Chakraborty developed an analytical solution to describe EOF of power-law fluids in microchannels . Zhao et al explored EOF of non-Newtonian fluids in slit and cylindrical microchannels, as well as their impact on EOF. ,− Tang et al employed the lattice-Boltzmann method to numerically analyze EOF of power-law fluids in microchannels, investigating the influence of fluid rheology on the flow pattern in a T -shaped microchannel. Zimmerman et al , simulated EOF of a Carreau fluid, highlighting the significant impact of non-Newtonian fluid characteristics on the flow field.…”

Effect of Membrane Thickness on Ion Transport in pH-Regulated Zero-Depth Interfacial Nanopores

“…Despite the notable achievements in this field, understanding the fundamental mechanisms governing ion transport and associated processes in zero-depth interfacial nanopores remains a critical issue that requires further investigation. The study of ion transport properties is highly important for current nanofluidic applications, − and numerous studies have been conducted in the area of modeling ion transport to understand the fundamental mechanisms. − However, few related theoretical studies provide experimental guidance for zero-depth interfacial nanopores. , Although Luan et al and Arjmandi-Tash et al described the electrical characteristics in zero-depth interfacial nanopores, they did not consider the effects of nanopore surface charge or electroosmotic flow (EOF), which have been proven to be unable to be completely ignored. − Meanwhile, although it is proven that the current passing through the interfacial nanopore has little to do with the membrane thickness, their research ignores the influence of the membrane thickness on other ion transport characteristics of interfacial nanopores. The membrane thickness, or the length of the nanopore, is an important parameter that affects ion transport.…”
