power transmission/ A4340 Structural acoustics and vibration A4630M Vibrations, aeroelasticity, hydroelasticity, mechanical waves, and shocksThe present letter is devoted to the low frequency pattern of acoustic radiation generated by the vibration of a circular elastic plate in unbounded space. The ...
Caused by the influence of triboelectric charges, electrostatic induction in TENG is simply a redistribution of electrons in metal electrodes. As a consequence, promotion of the contact electrification and maximization of the surface triboelectric charge density represents the most fundamental strategy for...
Energy-dissipation elastomers relying on their viscoelastic behavior of chain segments in the glass transition region can effectively suppress vibrations and noises in various fields, yet the operating frequency of those elastomers is difficult to control precisely and its range is narrow. Here, we repo...
The value of the coefficient is rising along with the growing stiffness of the composite.A critical damping ratio is a parameter describing free decaying vibration caused by non-conservative internal friction forces in the contact layer and in the bottom and top layer. The value of the ratio in...
The electrical energy can be drawn by the change of the capacity of a capacitor which change again is caused by the mechanical drive. This principle requires an initial load and a control of current flow. These functions are performed in a control circuit 12 which gets the output voltage of...
screening effect caused by high concentrations of counterions2. Despite the extensive research on osmotic energy conversion from mixing river and seawater, the practical application is still limited to laboratory scale under ideal conditions. Other high-salinity resources, such as industrial wastewater ...
In this respect, if the creases are small enough, the creases are considered to be insignificant imperfections that can be caused by imperfect fabrication processes. The membrane can have thickness variation across the cell, as the general principle is still applicable. The structure can be ...
172 This is caused by the preferential oxidation of iron and the resulting formation of Cu-rich regions which are melting during hot working.173 Copper contamination in iron scrap usually originates from end-of-life vehicles and home electronic appliances (Cu is a common metal used for the ...
(d) Voltage harvested by moving one, two and three droplets [16]; (e) DFT results for the distribution of differential charge near monolayer graphene caused by adsorbing one to three rows of hydrated sodium cations, and the corresponding adsorption energy (Ea) [16]; (f) Schematic ...
Another, external force might be caused by thermophoresis, which is not included in this study or any other study. By using expressions for the individual terms in Eq. (82), the authors describe the critical velocity by: (83)vp,crit=[H·(1+(1tanφ)2)rp·R2]107, where φ is the ...
