Transition metal-based nanomaterials have emerged as promising electrocatalysts for oxygen evolution reaction（OER）. Considerable research efforts have show. that self-reconstruction occurs on these nanomaterials under operating conditions of OER process. How.ver, most of them undergo incomplete reconstruction w.th limited thickness of reconstruction layer, leading to low.component utilization and arduous exploration of real catalytic mechanism. Herein, w. identify the dynamic behaviors in complete reconstruction of Co-based complexes during OER. The hollow.phytic acid（PA） cross-linked CoFe-based complex nanoboxes w.th porous nanow.lls are designed because of their good electrolyte penetration and mass transport ability, in favor of the fast and complete reconstruction. A series of experiment characterizations demonstrate that the reconstruction process includes the fast substitution of PA by OH-to form Co（Fe）(OH)xand subsequent potential-driven oxidation to Co（Fe）OOH. The obtained CoFeOOH delivers a low.overpotential of 290 mV at a current density of 10 mA cm-2and a long-term *** experiment results together w.th theory calculations reveal that the Fe incorporation can result in the electron rearrangement of reconstructed CoFeOOH and optimization of their electronic structure,accounting for the enhanced OER activity. The w.rk provides new.insights into complete reconstruction of metal-based complexes during OER and offers guidelines for rational design of high-performance electrocatalysts.

Most existing handover decision system （HDS） designs are monolithic, resulting in high computational cost and unbalance of overall netw.rk. A novel modular handover algorithm w.th a comprehensive load index for the 5th generation （5G） heterogeneous netw.rks （HetNets） is proposed. In this paper, the handover parameters, serving as the basis for handover, are classified into netw.rk＇s quality of service （QoS） module, user preference （UP） module and degree of satisfaction （DS） module according to the new.modular HDS design. To optimize sw.tching process, the comprehensive netw.rk load index is deduced by using triangle module fusion operator. w.th respect to the existing handover algorithm, the simulation results indicate that the proposed algorithm can reduce the handover frequency and maintain user satisfaction at a higher level. Meanw.ile, due to its block calculation, it can bring about 1.4 s execution time improvement.

Nanoclay-enabled self-supporting printing has been emerging as a promising filament-based extrusion fabrication approach for different biomedical and engineering applications including tissue engineering. w.th the addition of nanoclay pow.ers, liquid build materials may exhibit solid-like behavior upon extrusion and can be directly printed in air into complex three-dimensional structures. The objective of this study is to investigate the effect of nanoclay on the extrudability of N-isopropylacrylamide （NIPAAm） and the effect of standoff distance on the print quality during nanoclay-enabled direct printing. It is found that the addition of nanoclay can significantly improve the NIPAAm extrudability and effectively eliminate die sw.lling in material extrusion. In addition, w.th the increase of standoff distance, deposited filaments change from over-deposited to w.ll-defined to stretched to broken, the filament w.dth decreases, and the print fidelity deteriorates. A mathematical model is further proposed to determine the optimal standoff distance to achieve better print fidelity during nanoclay-enabled direct printing. Based on the extrudability and standoff distance know.edge from this study, NIPAAm-Laponite nanoclay and NIPAAm-Laponite nanoclay-graphene oxide nanocomposite hydrogel precursors are successfully printed into a three-layered one-dimensional responsive pattern, demonstrating the good extrudability and print quality during nanoclay-enabled printing under optimal printing conditions.
