If the air movement speed is too low, the electrostatic force will be stronger than aerodynamic forces and the web from nanofibres will be formed in the air between the spinnerets without wrapping the core yarn.
The capacitance gradient dC/dz is linearly proportional to the electrostatic force; the uncertainty of dC/dz will affect the force directly.
In addition to electrostatic forces, thermal, biological, and magnetic forces have also been used in these devices as a means of locomotion and manipulation of components (Pelesko & Bernstein 2003).
The acting electrostatic force gradients reduce the effective spring constant of the probe and, consequently, modify its resonance frequency.
The variables and parameters in (3), [F.sub.E], [E.sub.I], x, k, m, and b, are, respectively, the electrostatic force generated by the AC current, the electrostatic energy, plate distance, spring constant, mass of the movable electrode, and damping coefficient due to existing gas between plates.
The higher crystallinity in these two samples may be due to the finer fiber diameter between the large beads sizes unit as a result of electrostatic force during electrospinning.
Given that the electrostatic force is the gradient of the electrostatic energy and, in turn, the electrostatic energy is proportional to the capacity under constant voltage conditions, the electrostatic force is inferred to increase with a corresponding increase in capacity.
This [V.sub.DC] voltage difference sets up an electrostatic force of attraction and pulls the movable plate toward the fixed plate, thereby decreasing the distance of separation and increasing the capacitance.
This may be due to decrease in net positive centres on the surface of the sorbent due to adsorbed Cr (VI) species, resulting in weakening of electrostatic forces between sorbate and sorbent which ultimately leads to the reduction in the sorption capacity.
For the geometry depicted schematically in Figure A1, the electrostatic force between the tip (denoted by subscript T) and the substrate (denoted by subscript S), [F.sub.TS], can be obtained by integration using Equation (A1) or (A2) as follows:
Content includes research and reviews on SPM science and technology for all fields of science and engineering and cover such topics as magnetic force, electrostatic force, phase detection, biological materials, force modulation metals, semiconductors, composites, ceramics, and lithography.
Since the membrane is compliant, the push-pull electrostatic force applied to it causes it to move.
