This work focuses on optimization of 3D printed bioinspired helicoidal composites in design space of helicoidal angle and brick aspect ratio under dynamic three‐point bending loading by performing gaussian process regression‐based Bayesian optimization method. Firstly, the impact responses and crack modes of helicoidal structures under dynamic three‐point bending loading were studied through experiments...
The high cost of noble Pd/Pt required for the oxygen reduction reaction (ORR) in the cathode restricts the wide applications of fuel cells. In this study, the synthesis of a novel Pd3CuFe0.5 aerogel electrocatalyst is successfully demonstrated using self‐assembly and lyophilization techniques, employing a mild reducing agent. The resulting aerogel electrocatalyst exhibits a distinctive 3D network...
Global climate warming is accelerating permafrost degradation. The large amounts of soil organic matter in permafrost‐affected soils are prone to increased microbial decomposition in a warming climate. Along with permafrost degradation, changes to the soil microbiome play a crucial role in enhancing our understanding and in predicting the feedback of permafrost carbon. In this article, we review the...
