WebJul 2, 2013 · The electrostatic repulsive force from this HisCat cluster could provide some of the necessary force to translocate these α-helical segments during the structural rearrangement, although further analysis is necessary to confirm the role of this HisCat interaction in the fusion pathway. WebThe electrostatic actuation in the presented examples so far is based on attractive electrostatic forces. However, with a suitable design of cooperation, it is also possible to create repulsive electrostatic forces, as demonstrated first in , and later utilized by He et al. . The uplifting movement of a central plate in the work of He et al. is ...
WebElectrostatic interaction ( van der Waals interaction): The attractive or repulsive interaction between objects having electric charges. Electrostatic attraction (shown in red) between the δ + and δ - ends of a … Electrostatics is a branch of physics that studies electric charges at rest (static electricity). Since classical times, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, ἤλεκτρον (ḗlektron), was thus the source of the word 'electricity'. Electrostatic phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb's law.

The dielectric materials … WebThe absence of significant electrostatic force was revealed from the ionic-strength effect study. Binding-induced conformational variation in ct-DNA was absent in circular dichroism studies. Molecular docking studies suggested the position of DIC within the minor groove of ct-DNA, covering three base pairs long.
