The electrostatic transformer [PDF]

open access: yesNuclear 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

open access: yesPhysical 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.
