Electrochemical impedance spectroscopy as a diagnostic tool for passive direct methanol fuel cells

open access: yesEnergy Reports, 2022
Passive direct methanol fuel cells (pDMFCs) are a promising power source for portable electronic devices since they achieve higher power densities than the traditional batteries, and use a liquid fuel, methanol, which is easy to handle, storage and ...

Vapor-liquid equilibrium of acid gases with imidazolium-based ionic liquids using the UMR-PRU model

open access: yesChemical Thermodynamics and Thermal Analysis, 2022
The UMR-PRU group contribution equation of state (EoS), which couples the Peng-Robinson EoS with UNIFAC via the Universal Mixing Rules, is extended to pure imidazolium-based ionic liquids (ILs), as well as to their mixtures with CO2 and H2S.

Thermodynamic Parameters of Berberine with Kolliphor Mixtures Adsorption and Micellization

open access: yesMolecules, 2023
The poor solubility of berberine (Ber) in water limits its practical use. Its solubility can be increased, among other ways, by the addition of surfactants.
