Analysis of Arc Re-Ignition in Vacuum Interrupter-Based HVdc Circuit Breakers
The protection of HVdc systems has long been challenged by the absence of natural current zero-crossing, typically addressed using L-C branches. However, the phenomenon of multiple arc reignitions in vacuum interrupter (VI) based HVdc circuit breakers ...

Abstract Introduction The transition from military‐to‐civilian life is associated with challenges including shifts in identity and employment, reestablishment of family and personal relationships, and financial hardship. To better support transition, it is important to explore the perspectives of those who have transitioned from the Australian Defence ...

Pressure estimation in vacuum circuit breakers
The pressure of vacuum switching elements after production is checked normally by Penning or magnetron methods (combined electrical and magnetic field). Vacuum in the range of 10-1 to 10-4 Pa can be measured in this way. After assembly into circuit breakers however, these methods are not applicable. HF interruption performance during the make operation

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.

Hot Electron‐Informed Quantum Plasmonics in Nanoparticle‐on‐Mirror Nanocavities
A computational model for ultrafast optical modulation of quantum phenomena at plasmonic metal interfaces is developed. Focusing on nanoparticle‐on‐mirror nanocavities, it describes temperature‐induced variations in electronic quantum behavior. This facilitates analysis of quantum plasmonics in non‐equilibrium systems, thereby expanding the realm of ...

Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...
