“…The mean number of counter ions transferred from one contacting surface to the other one can be calculated following Ref. 32; these numbers are not equal because of the differences in the areas that are brought into contact during collision of the two spheres. We refer to the incident sphere and target sphere as sphere 1 and sphere 2, respectively.…”

This paper reports an experimental study of the contact electrification (CE) that happens when glass spheres of identical materials collide under different ambient relative humidity (RH) conditions. The experimental results indicate that the net charge on a sphere from a single collision is significantly altered by varying the RH level; the charge increases with increasing RH at low humidity, and then decreases at high RH conditions. The net charge reaches a maximum in the 20%–40% RH range. To explain the dependence of the CE on RH, we propose a model which yields predictions in agreement with the experimental data. The model also reveals how CE can be affected by temperature and surface absorption energy.

At present, the researchers mainly focused on the degradation of vegetation caused by the sand burial, the sand flowing, and the loss of soil moisture and nutrients but never considered the impact of strong environmental electric field, which caused by the moving sand particles, on the physiological process of plants. In this chapter, we briefly introduced the research progress of wind-blown sand electrification and proposed a coupling prediction model to explain the contact electrification phenomenon of moving sand. At last, based on the rigid conduit model and the root-water-uptake model, we discussed the effect of wind-blown sand electric field, which maximum value can reach to 200 kV/m, on the speed of plant sap flow, the water potential of root, and the cell membrane permeability, respectively. The numerical simulation results showed that the wind-blown sand electric field directly accelerates the sap flow rate and indirectly decreased the water potential of plant root, which finally affects the plant physiological processes. These results can explain why the effect of wind-blown sand on the plant is obvious than that of the clean wind. From these discussions, we effectively illustrate the impact mechanism of wind-blown sand on the plant physiology in the desertification land.So, we obtain the ion flux: Sand Electrification Possibly Affects the Plant Physiology in Desertification Land http://dx.doi.org/10.5772/intechopen.74976 95 Figure 8.

“…With the limitation of static sequence, almost either of these two kinds of materials is polymer. Contact electrification occurs not only between heterogeneous but also homogeneous materials, which has been demonstrated by several experimental works, such as silica-silica 24 25 26 27 28 29 , aluminum oxide-aluminum oxide 25 , polymer-polymer 30 31 32 . Some homogeneous materials based TENGs also have promising performance 33 .…”

Triboelectric nanogenerator (TENG) based on contact electrification between heterogeneous materials has been widely studied. Inspired from wind-blown sand electrification, we design a novel kind of TENG based on size dependent electrification using homogeneous inorganic materials. Based on the asymmetric contact theory between homogeneous material surfaces, a calculation of surface charge density has been carried out. Furthermore, the theoretical output of homogeneous material based TENG has been simulated. Therefore, this work may pave the way of fabricating TENG without the limitation of static sequence.
