Electrostatic Microgenerators [PDF]
Measurement and Control, 2008 Just as the electromagnetic force can be used to generate electrical power, the electrostatic force can also be used to convert mechanical energy into an electrical form. Electromagnetic generators are used in large power stations because scaling laws show them to be superior at larger sizes.

The electrostatic transformer [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1990 Abstract The electrostatic transformer (EST) has been developed to match the large-capacitance hadronic signal towers of liquid ionization calorimeters to relatively low-capacitance, low-noise preamplifiers. The intrinsically fast internal impedance transformation by the EST preserves the fast rise time required for effective calorimetry in the high ...

Self-charging electrostatic face masks leveraging triboelectrification for prolonged air filtration
Nature Communications, 2022 Electrostatic adsorption is an important complement to the mechanical filtration for high-efficiency air filtering. However, the electrostatic charge decays with time, especially in humid conditions.

The mechanism of an electrostatic nanofilter: overcoming entropy with electrostatics
Physical Chemistry Chemical Physics, 2023 General porins are nature's sieving machinery in the outer membrane of Gram-negative bacteria. In the diffusive transport process of molecules, electrostatic interactions can help to decrease the entropic free energy barrier.

Electrostatic tweezer for droplet manipulation
Proceedings of the National Academy of Sciences of the United States of America, 2022 Significance The manipulation of liquid droplets plays a crucial role in multidisciplinary applications. However, existing methods still face many challenges, such as short distance, low velocity, restricted operating conditions, the need for extra ...

On the Apparent Non-Uniqueness of the Electromagnetic Field Components of Return Strokes Revisited
Atmosphere, 2021 Recent research work shows that there are four procedures that can be used to calculate the electromagnetic fields from a current source. These different procedures, even though producing the same total field, give rise to field components that differ ...

Study on coupling effect between lightning electromagnetic field and unshielded multi-core cable
Journal of Hebei University of Science and Technology, 2015 In order to investigate the terminating load voltage of the unshielded multi-core cable coupled with lightning electromagnetic pulse(LEMP), we simulate LEMP within the bounded-wave transmission line which is input with a lightning surge signal produced ...
