Silver vanadate(Ag_(0.33)V_(2)O_(5))nanorods were successfully synthesized by the pre-intercalation of Ag+into the interlayer of V_(2)O_(5)through a sol-gel method,which presented a favorable electrochemical performance of high capacity,rate capacity,and cycle *** ally,Ag_(0.33)V_(2)O_(5)electrode presented a high capacity of about 311 mAh·g^(-1)at the current density of0.1 A·g^(-1).It also delivered long-term cycling stability(144 mAh·g^(-1)after 500 cycles at 2 A·g^(-1)).The reasons for the superior electrochemical performance were the preintercalation Ag^+extended interlayer distance,and the introduction of elemental silver improved conductivity during charge/***,the Zn^(2+)storage mechanism was revealed by various characteristic *** prepared Ag_(0.33)V_(2)O_(5)nanorods from the sol-gel method were demonstrated as a promising cathode material for aqueous Zn^(2+)batteries.

针对现有碰撞检测算法难以解决变形体碰撞的实时性和逼真性问题,提出一种基于可变形物体的碰撞检测算法。利用Snake模型对FDH包围盒进行更新,由于传统Snake模型存在弱边缘易溢出的问题,结合模拟退火算法(GASA)的遗传思想对其进行优化。实验结果表明,优化后的碰撞检测算法可快速准确得到碰撞物体的最佳轮廓曲线,弥补了遗传算法和模拟退火算存在的过早收敛和低收敛速度的问题,加快了包围盒的更新速度,提高了碰撞检测效率和逼真程度。

Porous organic cages(POCs)with permanent porosity and excellent host–guest property hold great potentials in regulating ion transport behavior,yet their feasibility as solid-state electrolytes has never been testified in a practical ***,we design and fabricate a quasi-solid-state electrolyte(QSSE)based on a POC to enable the stable operation of Li-metal batteries(LMBs).Benefiting from the ordered channels and cavity-induced anion-trapping effect of POC,the resulting POC-based QSSE exhibits a high Li+transference number of 0.67 and a high ionic conductivity of 1.25×10^(−4) S cm^(−1) with a low activation energy of 0.17 *** allow for homogeneous Li deposition and highly reversible Li plating/stripping for over 2000 *** a proof of concept,the LMB assembled with POC-based QSSE demonstrates extremely stable cycling performance with 85%capacity retention after 1000 ***,our work demonstrates the practical applicability of POC as SSEs for LMBs and could be extended to other energy-storage systems,such as Na and K batteries.
