Ionic mobility driven by correlated van der Waals and electrostatic forces.

Publication Type: Academic Journal

Source(s): Journal of Chemical Physics. 5/28/2022, Vol. 156 Issue 20, p1-7. 7p.

Abstract: Classical theories of dielectric friction make two critical assumptions: (i) friction due to van der Waals (vdW) forces is described by hydrodynamic drag and is independent of the ionic charge and (ii) vdW and electrostatic forces are statistically ind...

Direct calculation of the ionic mobility in superionic conductors.

Publication Type: Academic Journal

Source(s): Scientific Reports. 11/19/2022, Vol. 12 Issue 1, p1-10. 10p.

Abstract: We describe an approach based on non-equilibrium molecular dynamics (NEMD) simulations to calculate the ionic mobility of solid ion conductors such as solid electrolytes from first-principles. The calculations are carried out in finite slabs of the mat...

Interfacial Designing of MnO2 Half‐Wrapped by Aromatic Polymers for High‐Performance Aqueous Zinc‐Ion Batteries.

Publication Type: Academic Journal

Source(s): Angewandte Chemie International Edition. 12/5/2022, Vol. 61 Issue 49, p1-9. 9p.

Abstract: Due to the excellent specific capacity and high working voltage, manganese oxide (MnO2) has attracted considerable attention for aqueous zinc‐ion batteries (AZIBs). However, the irreversible structural collapse and sluggish ionic diffusion lead to poor...

A high-transmission axial ion mobility classifier for mass–mobility measurements of atmospheric ions.

Publication Type: Academic Journal

Source(s): Atmospheric Measurement Techniques. 2022, Vol. 15 Issue 12, p3705-3720. 16p.

Abstract: We present an electrical mobility classifier for mass–mobility measurements of atmospheric ions. Size segregation coupled with mass spectrometric detection of naturally occurring ions in the atmosphere is challenging due to the low ion concentration. C...

Effective Modulation of Ion Mobility through Solid-State Single-Digit Nanopores.

Publication Type: Academic Journal

Source(s): Nanomaterials (2079-4991). Nov2022, Vol. 12 Issue 22, p3946. 10p.

Abstract: Many experimental studies have proved that ion dynamics in a single-digit nanopore with dimensions comparable to the Debye length deviate from the bulk values, but we still have critical knowledge gaps in our understanding of ion transport in nanoconfi...
