Radiation protection safety and wear comfort of personal protective equipment (PPE) are of vital importance to nuclear personnel involved. Unfortunately, it is difficult for current PEE to meet the increasing requirements, which causes tremendous threats to health and reduced working efficiency. Here, a highly filled polymer fiber for textile‐based PPE to deal with the dilemma is put forward. PbWO4 (PWO) particles are superficially modified with styrene maleic anhydride (SMA) and then titanate coupling agent (bis(dioctyl pyrophosphate) ethylene titanate (BPET)) to form PWO@SMA‐BPET. After that, as high as 70 wt% PWO@SMA‐BPET/polyvinyl alcohol (PVA) fibers are obtained by solution blending and wet spinning in succession. Synergistic effects of surface modification with SMA and BPET lead to uniform dispersion PWO particles and good compatibility of interfaces in highly filled fibers. Importantly 36.6% γ‐ray (105 keV) shielding has been detected at three‐layer fabrics with 70 wt% PWO@SMA‐BPET/PVA fiber. Besides, the fabrics also display 116 mm s−1 of air permeability and 5388 g m−2 24 h of water vapor permeability, respectively. This work discloses synergistic effects on surface modification of high loading inorganic particles in polymer fibers, which give a further boost to γ‐ray shielding safety and wear comfort of PPE.

With the increase of wind power penetration in the power system, wind farm (WF) needs to limit active power and accurately track the instructions from the dispatch centre. Since a WF has many distributed wind turbines (WTs), it is a crucial issue to reasonably distribute power reference values to WTs. In this study, a novel active power dispatch (APD) strategy based on dynamic grouping of WTs is proposed. This strategy considers the characteristics and operating conditions of WTs, which can smoothen the power reference values to WTs and reduce fluctuations of key parameters of WTs. Then, a distributed dispatch strategy based on multi‐agent system consistency algorithm (MASCA) is applied for APD, which provides a dispatch strategy for WTs that does not require a centralised control centre. And the segmental virtual consistency algorithm is presented as an improvement of MASCA, which innovatively allows MASCA to support the grouping strategy for APD. Finally, the simulations show that the proposed strategy can enable WTs to obtain smoother reference power to track the dispatching instruction while reducing fluctuations of rotor speed and pitch angle, which is helpful to alleviate the fatigue of WTs. The dispatch strategy also shows good robustness when some communication is interrupted. [ABSTRACT FROM AUTHOR]

Abstract: Efficient ways are presented to accomplish photonic controlled‐phase‐flip gate and entangler with the assistance of imperfect double‐sided quantum‐dot‐microcavity systems, but without ancillary qubits. Compact quantum circuits for implementing entanglement swapping between photon pairs and electron pairs are then designed. Unity fidelities of the schemes can be achieved, and physical imperfections in the construction processes are detected by single‐photon detectors. Also, the efficiencies of the schemes can be further improved by repeating the operation processes when the undesired performances are detected. The evaluations show that the schemes are possible with current experiment parameters. [ABSTRACT FROM AUTHOR]
