Exact screening constraints for theories of inhomogeneous electrolytes: Generalized Stillinger–Lovett relations and a nonlinear Ward hierarchy

Exact theories of electrolyte structure must satisfy the nonlocal constraints imposed by electrostatic screening, yet these constraints are most commonly formulated only for homogeneous bulk systems and at the level of two-point correlations. Here, we develop a unified field-theo...

Advanced industrial-scale recycling of nickel waste alloys: a driver for circular economy objectives

An eco-friendly electrochemical method of nickel alloy waste leaching was developed for circular economy. The nickel concentration was 72.11 g/L in 100 g/L HCl after 90 A·h, 60 °C and 5 A/dm2 current, while 37.37 g/L nickel was obtained in 100 g/L H₂SO₄ under these conditions. Th...

Water and Hydrogen Bond Donor Effects on Mass Transport and Copper Electrodeposition in Deep Eutectic Solvents

Abstract Choline chloride-based deep eutectic solvents (DESs) are promising for electrodeposition due to their high electrochemical stability and ionic conductivity, yet their application can be hindered by high viscosity and uncontrolled water uptake. Here, we systematically inv...
