On‐Demand, Contact‐Less and Loss‐Less Droplet Manipulation via Contact Electrification [PDF]

open access: goldAdvanced Science
While there are many droplet manipulation techniques, all of them suffer from at least one of the following drawbacks – complex fabrication or complex equipment or liquid loss. In this work, a simple and portable technique is demonstrated that enables on‐

Contact Electrification by Quantum-Mechanical Tunneling [PDF]

open access: goldResearch, 2019
A simple model of charge transfer by loss-less quantum-mechanical tunneling between two solids is proposed. The model is applicable to electron transport and contact electrification between e.g. a metal and a dielectric solid.

Flow-sensory contact electrification of graphene [PDF]

open access: yesNature Communications, 2021
Electrical nano-sensors hold promise for biofluid interrogation, but their performance is still below the state of the art. Here, self-powered monolayer graphene microelectrodes are shown to enable real-time interrogation of whole-blood flows with 6 ...

Spin-selected electron transfer in liquid–solid contact electrification [PDF]

open access: yesNature Communications, 2022
Electron transfer has been shown to contribute to contact electrification at liquid–solid interface. Here, authors investigate the magnetic field effect on the liquid–solid electron transfer and propose a spin conversion model for the liquid–solid ...

Towards time-dependent, non-equilibrium charge-transfer force fields: Contact electrification and history-dependent dissociation limits [PDF]

open access: green, 2013
Force fields uniquely assign interatomic forces for a given set of atomic coordinates. The underlying assumption is that electrons are in their quantum-mechanical ground state or in thermal equilibrium.
