With the rapid progress in micro/nanofluidics, understanding fundamental mechanisms of ionic transport, fluid behavior, and microsystem dynamics is more crucial than ever. Given substantial expenses associated with manufacturing such systems, computational simulations offer a cost-effective avenue for advancing this industry sector while minimizing financial burdens. In context, current study explores impact electrolyte characteristics by numerically analyzing electroosmotic flow (EOF) conical nanochannel featuring charged slippery surfaces coated polyelectrolyte layer. Two types electrolytic fluids, namely, water (representing Newtonian fluid) blood plasma non-Newtonian fluid), were investigated. The behavior electrolytes was modeled using Bingham–Papanastasiou model. governing equations nonlinear model, Poisson–Nernst–Planck Navier–Stokes equations, solved finite element method. Various parameters including slip length, surface charge density, soft layer concentration systematically adjusted to assess three key aspects: EOF, selectivity, rectification. findings revealed that increasing length significantly enhanced EOF both electrolytes. For instance, platelets within core increased 1.5 times extension from 0 10 nm. Additionally, applying positive voltage amplified particularly when wall charges similar. example, decreasing density −0.02 C/m2 led 1.5-fold increase platelet rising 0.028 0.042 m/s.

This work estimates Michaelis-Menten kinetics parameters for nutrient transport under varying flow rates in the soft roots of Indian mustard (Brassica juncea) using a plant fluidic device. To find metallic components within roots, inductively coupled plasma mass spectrometry (ICP-MS) analysis was performed. The rate-dependent metabolic changes were examined Raman spectral analysis. In addition, three-dimensional numerical simulations conducted to assess mechanical stresses resulting from concentration difference that enhances osmotic pressure and loading at root-liquid interface. Convection, primary mode flowing media, observed reduce uptake higher rates. contrast, diffusion became more prevalent areas where complex root structure restricted field. gradient between upstream downstream regions caused upstream. As seen, an increase rate resulted decrease length due reduction advantageous metabolites, which led lower average stress loading. Additionally, interface found over time.
