All‐inorganic perovskites have attracted increasing worldwide interest due to its significantly improved stability in atmospheric environment compared to organic–inorganic hybrid perovskites, which renders it infinitely applicable in many fields such as electronics, optoelectronics, and energy storage. However, all‐inorganic perovskites have to confront the challenges from fabrication before their wide utilization in the aforementioned applications. Liquid‐phase synthesis holds the advantage of mass production and easy modulation of composition but with the deficiencies of relatively low crystallinity and disordered products. Interestingly, gas‐phase growth has complementary characteristics compared to the liquid‐phase method. In this work, it is proposed that a novel temperature difference triggers growth strategy to integrate the merits of the liquid‐ and gas‐phase methods, and the feasibility of this strategy via a simple lab‐use hot plate is demonstrated. High quality all‐inorganic perovskites, cesium lead halide (CsPbX3) nanowire arrays, can be epitaxially grown as in a gas‐phase method, but at the same time, the composition of products can be easily modulated by predesigning the recipe of precursors as in the liquid‐phase method on a large scale. Notably, the as‐fabricated CsPbX3 perovskite nanowire arrays demonstrate excellent stability and good optoelectronic properties in air. It is believed that this novel strategy can strikingly prompt the development of perovskites fabrication and applications in future.

Constrained layer dampers (CLD) are in widespread use for passive vibration damping, in applications including aerospace structures. However, the introducing of the damping layer can reduce the stiffness of the sandwich structures. A viscoelastic material filling (VMF) is chosen to balance structural and vibrational performance of lattice truss in this work. The recently brought forward 3D Kagome truss with face sheet was manufactured by selective laser sintering technology and the thermosetting polyurethane was chosen as the viscoelastic filling material. A novel complex modal analysis finite element method for Hybrid composite lattice truss sandwich is introduced in this paper. Dynamic analysis experiment results show that the VMF method is found to be effective in reducing the vibration amplitude and it has the potential for band-gap design. The VMF method can provide high stiffness at low mass and considerable vibrational performance at low cost and it can be considered as a general vibration design method in lattice truss manufacture.
