A General Classification of Electrolyte Solutions Based on Their Charge and Mass Transport Properties [PDF]
arXiv, 2021 The conventional classification of electrolyte solutions as 'strong' or 'weak' accounts for their charge transport properties, but neglects their mass transport properties, and is not readily applicable to highly concentrated solutions. Here, we use the Onsager transport formalism in combination with linear response theory to attain a more general ...

Ion specificity modulated inhomogeneous interfacial flow inhibits bubble coalescence in electrolyte solutions [PDF]
, 2020 Inhibition of bubble coalescence in electrolyte solutions enables the formation of oceanic whitecaps and affects the heat and mass transfer in many bubble related engineering processes. For different electrolytes, the ability to inhibit bubble coalescence correlates to the ion specificity at the air water interface at an abnormal cation-anion pair ...

Re-discovering micro-emulsion electrolytes: a biphasic electrolyte platform for Organic redox flow batteries [PDF]
arXiv, 2021 Redox flow batteries (RFBs) have gained popularity as large-scale energy storage systems for wind and solar powered grids. Modern RFB systems are based on highly corrosive and/or flammable electrolytes. Organic redox active species for RFBs are gaining commercial traction, but there is a trade-off in choosing aqueous or non-aqueous electrolytes in ...
