Prussian blue analogs (PBAs) face two major challenges in sodium-ion batteries: sodium content that falls below the theoretical value and difficulty of dehydrating crystal water their applications. This study proposes a one-step presodiation dehydration strategy for PBA nanostructures, resulting electrode (H-PB) with both low high through use benzophenone. minimizes reabsorption during preparation eliminates need secondary drying. The H-PB half-cell achieves an initial Coulombic efficiency...
Sodium‐rich Prussian blue analogs (PBAs) are promising cathode candidates for sodium‐ion batteries, offering high crystallinity, excellent electrochemical performance, and low cost. However, traditional hydrothermal synthesis often necessitates acid treatment, which presents a safety risk due to the potential release of toxic hydrogen cyanide (HCN). Inspired by sodium thiosulfate (Na2S2O3) as known antidote, we developed novel method that mitigates risks HCN leakage, yields...
For asteroid landing missions in uncertain environments, the thrust commands determined by a feedback control and fuel-optimal trajectory may exceed allowable magnitude, which affects stability of controller. In contrast to traditional method that designs nominal law separately, novel closed-loop guidance generates an optimal while designing stable within limit is proposed. The incorporates design into optimization shaping controlled bundles contractive invariant set centered on trajectory....
This article presents a novel spatial parallel mechanism with kinematic redundancy. The design strategy and evolution of the proposed is introduced, model established. To simplify singularity analysis this kind mechanism, virtual plane method which can separate whole into two parts presented. relative Jacobian matrices are established illustrated configurations three types. Kinematic performance obtained to see redundancy effects on mechanism. orientational workspace by regions angles varied...
Launching underwater gliders by aircraft could greatly expand the application of gliders. However, during process glider entry into water, it will be subjected to significant impact loads, especially wing water. In this paper, a foldable module is proposed reduce water loads caused wings entering The effect on reduction and influence trajectory are studied numerical method. results show that differences in mass gravity center position have little until When enters obliquely, reduces peak...
Incorporating recuperators into turbine engines which enables the heat transfer between exhaust gas and compressed air, indicates considerable potential for lower emissions SFC (specific fuel consumption). However as a matter of fact, they have not yet found wide acceptance in aircraft applications. One main disadvantages is because such situations system overall weight needs to be strictly controlled, there are concerns that beneficial saving may offset additional bulk recuperator. In this...
Abstract In modern aviation power systems, the dynamic stability of generation systems has become a major challenge. To tackle issues such as slow response, poor voltage stability, and oscillations in aircraft synchronous generators under sudden load changes, Proportional-Integral-Derivative (PID) regulator modified using Differential Evolution (DE) algorithm been developed. Additionally, DE algorithm’s convergence speed robustness are enhanced through incorporation directional search...
Abstract The growing demand for highly efficient, environmentally friendly aero-engines highlights the incorporation of recuperators into gas turbine systems, which is especially attractive rotorcraft powerplants, as majority their mission time spent at part load cruise power (typically above 60%) with non-optimum specific fuel consumption (SFC) characteristic. In this work, a primary surface recuperator (PSR) 300kW-class powerplant considered optimization by using Genetic Algorithm (GA). By...
