The complex phase transitions of lithiated phosphorus (P) species-derived interfacial side reactions can be substantially mitigated through a triple-anion coordination design within the solvation sheath. Our results indicate that the triple-anion electrolyte exhibits an expanded energy level distribution of solvation sheaths, a low barrier for migrating Li solvation sheath, a high Li-anion coordination number, a low Li-ether solvent coordination number and an effective NO -FSI-TFSI adsorption-decomposition-sustained release cooperative mechanism that generates a robust rigid-soft coupled SEI layer during the cycling process. When coupled with a LiFePO cathode, the full cell utilizing the triple-anion ether electrolyte demonstrates superior stability compared to cells using commercial LiPF-EC/DEC electrolytes.

This paper addresses the trajectory tracking control of a Gough-Stewart platform (GS platform) with an uncertain load. The uncertainty of this load leads to external disturbance to the parallel robot, which affects the dynamic coupling among the six degrees of freedom (DOF) and the tracking performance. Even though many researchers focus on improving the system robustness and tracking accuracy, there still exist two main problems: the system's internal uncertainties, including the modeling, manufacturing, and assembly errors of the parallel robot affect the control accuracy; the uncertain external disturbance varies in an extensive range and reduces the stability and tracking accuracy of the system.

In this article, an accelerated value iteration-based safe Q-learning (SQL) algorithm is developed to design the tracking controller for unknown nonlinear systems. First, an augmented Q-function, consisting of a quadratic utility function and an adjustable positive-definite control barrier function (CBF), is devised to ensure both the optimality and safety of the tracking controller. The quadratic utility function, associated with optimality, guarantees that the tracking controller can eliminate the ultimate tracking error, regardless of the reference trajectory.

We report the synthesis, crystal structure, and physical properties of the mixed transition-metal oxyarsenide SrVCrAsO. The compound has an ordered intergrowth structure with the perovskite-like layers of "SrVO" and the ThCrSi-type layers of "SrCrAs" stacking alternately along the crystallographic axis, in which ∼10% mixed occupancy between V and Cr is present for the sample synthesized by solid-state reactions. The electrical resistivity data show semiconducting-like behavior, probably associated with the occupancy disorders in the CrAs layers.

In order to demonstrate the formation of laser-induced periodic surface structures (LIPSS), simulations were performed to investigate the effect of multiple femtosecond laser pulses with different laser energy densities on a Ti6Al4V surface. In this work, a set of partial differential equations calculating the electron and lattice temperature variations, followed by coupling with an electric field, is used to analyze the evolution of the periodic surface structure induced by the interaction of the femtosecond laser with the material. As the number of pulses increases, the surface structure of the material changes from none to produce LIPSS structure and from low spatial frequency LIPSS (LSFL) structure to high spatial frequency LIPSS (HSFL) structure.
