Nanofluidization electrostatics [PDF]
Physical Review E, 2008 Electrostatic charging of powders is a relevant phenomenon for a number of industrial applications. The design of new processes and the use of high resistivity materials and ultrafine powders may lead to higher charging rates and to higher levels of charge accumulation that can become a serious problem.

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. However, on the micro-scale, the electrostatic force becomes

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 ...

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.
