In contrast to the band at 1650 cm−1, the band at 3200–3600 cm−1 can be primarily explained by a proton motion along the O–H axis, that is, the stretching vibration (Fig. 5a, b). Together, the rotational contributions to the 1650 cm−1 mode make the orientation of ...
Vibration-based energy harvesting techniques face difficulties with the resonant frequency of the environment and output power [44]. To address these issues, researchers have explored the design of new materials to adjust the resonance frequency and improve the devices’ performance over a wide ...
The strength of this interaction is described by a Drude spectral density with associated reorganization energy λ and cutoff frequency Ωc<KBT as described in the Methods section. We consider the exciton and vibration parameters to the PEB50 dimer and investigate the trends as functions of the ...
Understanding the effects of thermoelastic coupling on the natural frequency of micro- and nanoscale resonators is essential for the design of frequency-se... S Prabhakar,MP Pa?Doussis,S Vengallatore - 《Journal of Sound & Vibration》 被引量: 46发表: 2009年 Synchronization of many nanomechanical...
These molecules shake nearest neighbor air molecules until the energy of vibration is dissipated to the point of extinction through friction and heat. By changing the shape of the mouth as well as the vibration of the vocal chords, a person can modulate the tone and generate words and ...
have three-dimensional electronic structures and isotropic thermoelectric transport properties, despite their α-NaFeO2-type layered crystal structure [64]. This apparent contradiction can be explained by the fact that the bottom of the conduction bands in these compounds is composed of Zr\(4{d}_{...
vibration and perturbation of the conditions at the surface of the devices. As explained in detail below, design and fabrication of circuit elements with such resonator elements may be done using the same technology as is used for fabricating the driving circuit, thus providing for efficient fabrica...
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...
showed a photomechanical vibration of basilar membrane when it was irra- diated directly with a 930 nm laser41. The irradiation resulted in a local initial passive mechanical deflec- tion of the basilar membrane. In pristine cochleae, this initial basilar membrane movement was followed by a ...
As the frequency increases, the vibration acceleration will also become larger, which can effectively contact and help the friction layer to accumulate more charge. Increasing the frequency further does not increase the Voc, and when the contact area does not change with frequency, the VOC reaches...
