Study on the Method of Charge Accumulation Suppression of Electrostatic Suspended Accelerometer

Sensors, 2022
Electrostatic suspended accelerometers (ESAs) are widely used in high accuracy acceleration measurement. However, there exist accumulated charges on the isolated mass which damage the accuracy and the stability of ESAs. In this paper, we propose to apply

Direct numerical simulation of forced flow dielectric EHD within charge injection atomizers [PDF]

, 2010
A charge injection atomizer functions by introducing electric charge discharged from a high voltage electrode into a dielectric liquid, which subsequently atomizes the ejected liquid jet.

ELECTROSTATIC CHARGE GENERATED ON FLOOR IN HOSPITALS [PDF]

Journal of the Egyptian Society of Tribology, 2017
The present work investigates two floor materials that are used in hospitals, operating rooms, intensive care units and factories. It is proposed to measure the electrostatic charge (ESC) generated on polypropylene shoes during walking against the tested

Image charge inclusion in the dielectric sphere revisited [PDF]

, 2012
Van Siclen (1988 Am. J. Phys. 56 1142) reported a curious property of a dielectric sphere in the field of an external point charge: the field outside the sphere generated by the combination of the original charge exterior and the Kelvin image charge ...

Electrostatic contributions to the kinetics and thermodynamics of protein assembly. [PDF]

, 2005
The role of electrostatic interactions in the assembly of a native protein structure was studied using fragment complementation. Contributions of salt, pH, or surface charges to the kinetics and equilibrium of calbindin D(9k) reconstitution was measured ...

Salting the charged surface: pH and salt dependence of protein G B1 stability. [PDF]

, 2006
This study shows significant effects of protein surface charges on stability and these effects are not eliminated by salt screening. The stability for a variant of protein G B1 domain was studied in the pH-range of 1.5-11 at low, 0.15 M, and 2 M salt ...
