We present a detailed theoretical study on the photoionization of oneand two-electron atoms subject to an external changing plasma environment based on the Debye-Hückel model. Specifically, by examining the migration of the bound excited states into the continuum in the presence of plasma, our investigation has led to resonancelike photoionization structures immediately above the ionization thr...

The electrical conductivities of the dilute solutions containing ionic liquids (1-hexyl-3-methylimidazolium chloride [Hmim]Cl, 1-hexyl-3-methylimidazolium bromide [Hmim]Br, and iodide [Hmim]I) with water isopropanol were determined in temperature ranging from 293.15 to 313.15 K. liquid densities all binary mixtures further for model parameterization. In theoretical modeling, limiting molar Λ0(T...

In the present work we use a selfconsistent version of the EHT to study the electronic transport in metallic carbon nanotubes (CNTs) with various metallic electrodes (Al, Cu, Pd, Pt, Ag, Au). While the electronic structure of the metals is well described by the extended Hückel (EH) parameters of Cerdá [1], we show that a new parameter set for carbon strongly improves the agreement between EHT a...

We consider a classical two-component plasma analog of the restricted primitive model electrolyte, where hard-core interaction is replaced by soft differentiable potential. Within Born–Green–Yvon hierarchy for equilibrium distribution functions, we shed light on an infection mechanism charge correlations are polluted density at critical point liquid–gas transition. This should imply algebraic d...

This work presents new semi-analytical solutions for the combined fully developed electro-osmotic pressure-driven flow in microchannels of viscoelastic fluids, described by generalised Phan-Thien–Tanner model (gPTT) recently proposed Ferrás et al. (Journal Non-Newtonian Fluid Mechanics, 269:88–99, 2019). version PTT a function trace stress tensor—the Mittag–Leffler function—where one or two fit...
