Electric-field mediated chemistry: uncovering and exploiting the potential of (oriented) electric fields to exert chemical catalysis and reaction control.

Journal of the American Chemical Society, 2020
This Perspective discusses oriented external-electric-fields (OEEF), and other electric-field types, as 'smart reagents', which enable in principle control over wide-ranging aspects of reactivity and structure.

Promoting Electrocatalytic Hydrogen Evolution Reaction and Oxygen Evolution Reaction by Fields: Effects of Electric Field, Magnetic Field, Strain, and Light

Small Methods, 2020
high-purity hydrogen production. However, the sluggish dynamics of its two half-reactions, hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), are tough challenges impeding the practical application of this technology.

Electric-field control of magnetism in a few-layered van der Waals ferromagnetic semiconductor

Nature Nanotechnology, 2018
Manipulating a quantum state via electrostatic gating has been of great importance for many model systems in nanoelectronics. Until now, however, controlling the electron spins or, more specifically, the magnetism of a system by electric-field tuning has

Electric field-assisted biosorption

Biotechnology Letters, 2004
A bisorption process using electric fields to facilitate contact between a sorbate and non-living biomass is described. The latter is enclosed within a semi-permeable membrane together with an electrode. The counter electrode is placed in the sorbate solution and an established potential across the electrodes facilitates electrokinetic movement of the ...

Electric Field Reversal in Sprite Electric Field Signature

Monthly Weather Review, 2013
Abstract In measurements of the electric field associated with the current of a sprite 450 km from ground-based field sensors, it was observed that the sign of the electric field was positive when positive charge was lowered from the ionosphere.

Electric field gradient focusing

Journal of Separation Science, 2005
AbstractElectric field gradient focusing (EFGF) is a relatively new separation technique with promising attributes, particularly for protein analysis. The fundamental fractionation mechanism in EFGF involves a gradient in electric field along the length of a separation column.

Electric-field-driven switching of individual magnetic skyrmions.

Nature Nanotechnology, 2016
Controlling magnetism with electric fields is a key challenge to develop future energy-efficient devices. The present magnetic information technology is mainly based on writing processes requiring either local magnetic fields or spin torques, but it has ...

Electric‐Field‐Driven Deracemization

ChemPhysChem, 2006
AbstractWe demonstrate, both theoretically and experimentally, that it is possible to use an electric field to drive the formation of macroscopic chiral (conglomerate) domains from an initially homogeneous fluid racemate. Field‐induced segregation is exhibited in a fluid smectic liquid‐crystal phase of a racemic mesogen, wherein enantiomerically ...

Microreactors with Electrical Fields

2010
The use of electric fields in chemistry is considered an important concept of process intensification. The combination of electricity with chemistry becomes particularly valuable at smaller scales, as they are exploited in microreaction technology. Microreactor systems with integrated electrodes provide excellent platforms to investigate and exploit ...
