Laser &Photonics Reviews, EarlyView.Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

Influence of UHV GIL access on transient recovery voltage of circuit breaker
电力工程技术, 2022 The access of ultra high voltage (UHV) gas-insulated transmission line (GIL) affects both the transient recovery voltage (TRV) amplitude and the rate of rise of TRV (RRRV) of circuit breakers,which may endanger the breaking capacity of circuit breakers ...

Interlink Hybrid DC Circuit Breaker [PDF]
IEEE Transactions on Industrial Electronics, 2018 —To protect HVDC grids from DC faults, the concept of a hybrid DC circuit breaker is widely accepted due to its low conduction losses and fast interruption speed. For a well-built DC grid, a massive number of hybrid DC circuit breakers have to be installed. This will lead to high capital costs.

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.This paper proposes a decentralized electric vehicle (EV) charging control method designed to clear voltage violations in distribution grids with high EV penetration, while considering consumer convenience. The concentration of EV charging demand can cause localized voltage violations, posing a significant challenge to grid operation.
