Contact Electrification via Redox-Active Molecules. [PDF]

open access: yesAngew Chem Int Ed Engl
Abstract Contact electrification, as the transfer of charge upon the contact of two (dis)similar materials, is strongly influenced by surface chemistry, which governs the efficiency of charge separation. For harvesting electrical energy from mechanical energy, material pairs with high electron‐transfer efficiency ...

Recent Progress of Chemical Reactions Induced by Contact Electrification [PDF]

open access: yesMolecules
Contact electrification (CE) spans from atomic to macroscopic scales, facilitating charge transfer between materials upon contact. This interfacial charge exchange, occurring in solid–solid (S–S) or solid–liquid (S–L) systems, initiates radical ...

On chain models for contact electrification [PDF]

open access: yesJournal of Physics: Condensed Matter, 2022
Abstract An exact analytical model of charge dynamics for a chain of atoms with asymmetric hopping terms is presented. Analytic and numeric results are shown to give rise to similar dynamics in both the absence and presence of electron interactions.
