Microreactors with Electrical Fields
2010The 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 ...

This chapter is concerned with time-independent electric fields arising from fixed or static charges and hence the term electrostatic field is often used. The starting point is usually from the experimental investigations carried out in 1785 by Cavendish and Coulomb, who likened the electrostatic field associated with the charge on a body to the ...

The purpose of the first chapter in this book was summarized in Sect. 1.1. It was intended to provide a brief overview of the most important measuring instruments for electric current and voltage (potential difference). To this end, we introduced some of the basic concepts of electromagnetism.

Electric Field Reversal in Sprite Electric Field Signature
Monthly Weather Review, 2013Abstract 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.

Journal of Food Safety, 2000
Srope of Deliverables: This section discusses current knowledge in the application of pulsed electric fields as a method of non‐thermal food preservation. It includes mechanisms of inactivation, studies on microbial inactivation, critical process factors, and future research needs. Detailed descriptions of pilot and laboratory‐scale equipment and their

Electric-field-driven switching of individual magnetic skyrmions.
Nature Nanotechnology, 2016Controlling 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 ...

In this work we show that the rate-dependent hysteresis seen in current–voltage scans of CH3NH3PbI3 perovskite solar cells is related to a slow field-induced process that tends to cancel the electric field in the device at each applied bias voltage.

Gravitation was the first force to be discovered among the fundamental forces of nature. Electricity and magnetism only came to be understood later, around the 1600s. But electric and magnetic forces shape natural events and play a major role, perhaps the most significant role for living things and for technology.

The Electric Field and the Electric Potential
1991We have seen in the preceding chapter how the presence of an electric charge has an effect on another electric charge. This raises the question: What if there is only one electric charge present? The idea of an electric field is introduced to describe the effect in all space around a charge so that if another charge is present we can predict the effect
