Efficient Charging of Li‐Ion Batteries with Pulsed Output Current of Triboelectric Nanogenerators

The triboelectric nanogenerator (TENG) is a promising mechanical energy harvesting technology, but its pulsed output and the instability of input energy sources make associated energy-storage devices necessary for real applications. In this work, feasible and efficient charging of Li-ion batteries by a rotating TENG with pulsed output current is demonstrated. In-depth discussions are made on ho...

Numerical Techniques for Studying Repetitively Pulsed Reactor Time-Dependent Behavior

Computationally efficient numerical techniques are developed for studying the time-dependent behavior of repetitively pulsed reactors. Reactivity perturbations synchronous with the external pulse are also considered. Three types of reactivity are considered: step change, sinusoidal, and thermal feedback. Noniterative techniques, based upon Laplace transforms and residues, are used to solve the ...

Electric field measurement in repetitively pulsed nanosecond discharges in a high pressure hydrogen environment

Electric fields of repetitively pulsed nanosecond discharges have been measured from electric-field induced Raman scattering by hydrogen molecules. Especially the temporal evolution of the electric field spatial distribution was recorded. With a high-speed optical emission intensity analysis, it has been found that most ionization events take place within a very short period during an ionizatio...

A Review of High Beam Current Rfq Accelerators and Funnels*

We review the design features of several high-current (>20-mA) and high-power (>1-mA average) proton or H injectors, RFQs, and funnels. We include a summary of observed performance and will mention a sampling of new designs, including the proposed incorporation of beam choppers. Different programs and organizations have chosen to build the RFQ in diverse configurations. Although the majority of...
