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 frequency range. One such material is a metamaterial, which is an rtificial material with periodic microstructure and special properties ...
This paper introduces an optimized DC–DC converter that employs a modified switched inductor-capacitor technique to achieve ultra-high voltage gain for renewable energy systems. The development is based on adding one cell of modified switched inductor (
The Förster resonance energy transfer (FRET) is the phenomenon of transferring the energy of the electronic excited state of a fluorophore called a donor to a chromophore called an acceptor. From: Methods in Cell Biology, 2019 About this pageSet alert ...
Detangling electrolyte chemical dynamics in lithium sulfur batteries by operando monitoring with optical resonance combs The shuttle effect of polysulfides in lithium sulfur batteries leads to performance degradation. Here, authors use fiber-based sensors to track and quantify the dissolved polysulfide concen...
This work is devoted to study of the process e+e−→ηηγ (1) in the center-of-mass (c.m.) energy range s=1.17–2.00 GeV at the experiment with the SND detector at the VEPP-2000 e+e− collider. Previously, this process was studied only near the J/ψ resonance by the Crys...
redox co-catalyst: (i) the semiconductor absorbs light upon irradiation when absorbed light energy is greater than the bandgap of the material, (ii) electron excitation from the valence band (VB) to the conduction band (CB), leaving holes in the VB simultaneously, and (iii) charge migration...
Microwave energy based chemical synthesis has several merits and is important from both scientific and engineering standpoints. Microwaves have been applied in numerous inorganic and organic chemical syntheses; perhaps, from the time their ability to wor
[13]. In electromagnetic energy harvesting, the maximum power transfer to the load depends upon the inductance, and this inductance could be used to tune resonance to get the peak power [14]. However, in this energy harvesting, it is difficult to get the maximum power when nonlinearities are...
The major metrics of performances are the minimum input RF power that can start-up the EH system, the open-voltage at the targeted input RF power level and the effective efficiency when the rectenna is loaded with an impedance equal to its internal impedance (optimal load condition) [3]. ...
The geometric and physical properties of the HEH considered for the analysis are shown in Table 1. The hybrid structure of the device is scalable and tunable. The tip mass and the length of the comb electrodes can be adjusted to operate at the resonance frequency (Rahman and Chakravarty 2018...
