Here we report figure-of-merits for defining the performance of a triboelectric nanogenerator, which is composed of a structural figure-of-merit related to the structure and a material figure of merit that is the square of the surface charge density. The structural figure-of-merit is derived ...
Given the characteristics of SiNW FET devices, variations in the surface charge density close to the NW surface can significantly contribute to the measured signals. In this study, bis-tris propane (BTP) was used to replace conventional mineral buffers in various biological applications. BTP is a...
The amount of electric charge per unit dimension is the electric charge density. A conductor's electric charges could be spread along its length, across its surface, and through its volume.
Using the relation between the hemoglobin dissociation constant and charge, together with the estimated number of pores in the axon membrane, we have derived a relation between the fraction of pores open and the surface charge density. When this latter relation is incorporated into the surface ...
(2) Use "Integration of Surface Charge Density (es.nD)" There are two cases I tested. One is the film without pre-stress, and the other is the film with pre-stress. For the without pre-stress case, it seens fine that the charge value to ...
If we consider the AFM tip as a sphere and the sample as a flat plane, then the force, F, is described by(1){formula not available us MathML}where R is the radius of the sphere, D the tip-sample separation distance, σR the surface charge density of the sphere, σS the surface...
1, lower). As the poly-L-ornithine concentration was increased, the positive charge density on the surface also increased, and the DNA molecules assumed more compact conformations with dramatically decreased, average end-to-end distance (Fig. 1, upper). However, on all of the surfaces ...
At an ideal boundary, where the polarization is uniform and extended infinitely in the direction perpendicular to the boundary, a polarization discontinuity ΔP across the boundary will result in the surface charge density n2D = ΔP/e. Figure 2 shows the n2D calculated as a function of ...
For TENG devices, the surface charge density, which dominates output performance, is inevitably limited by the air-breakdown effect between two tribo-surfaces10,11,12,13,14,15. In contact-separation mode TENG, derived from Paschen’s law and TENG parallel-plate model, the effect of dielectric ...
