Effect of Potential Distribution of Main Shield on Internal Insulation Performance of Vacuum Interrupter

Shanghai Jiaotong Daxue xuebao
As an environmentally friendly switchgear technology, vacuum circuit breakers have a wide range of application prospects. However, both single and break vacuum circuit breakers face the issues of uneven potential distribution in the main shielding case ...

The Superconducting Toroid for the New International AXion Observatory (IAXO)

, 2013
IAXO, the new International AXion Observatory, will feature the most ambitious detector for solar axions to date. Axions are hypothetical particles which were postulated to solve one of the puzzles arising in the standard model of particle physics ...

Charge Transport Across Single Molecules at the Metal–Superconductor Interface

Small, EarlyView.
The evolution of Andreev reflection in single‐molecule junctions is probed with the decreasing distance between a normal‐metal tip and a conventional superconductor. Andreev reflection becomes most effective when a molecular orbital straddles the Fermi level.

Cascaded commutation circuit for a hybrid DC breaker with dynamic control on fault current and DC breaker voltage [PDF]

, 2017
This paper proposed a cascaded commutation circuit based on current commutation approach for low-to-medium voltage DC fault current interruption, without snubber circuits, which slows the fault current di/dt prior to current-zero and the rate of rise of ...

Electrospun PAN Membrane Loaded with AgInP2Se6 Nanosheets for Triboelectric Energy Harvesting

Small, EarlyView.
Exfoliated AgInP2Se6 nanosheets are incorporated into a polyacrylonitrile (PAN) polymer matrix by electrospinning and applied for the first time in a triboelectric nanogenerator (TENG). The hybrid membrane delivers strong electrical output and exhibits reversible humidity sensitivity, responding rapidly to changes in relative humidity.
