Functional tetrapodal zinc oxide: from synthesis and multiphysics to advanced applications

diverse and often competing effects. These properties are typically intertwined, producing physical coupling that generates both performance synergies and fundamental design trade-offs. The utility of this architecture is demonstrated in two principal domains: first, as an active functional particle network leveraging geometric stress concentration and percolation effects for applications such as advanced sensing; and second, as a sacrificial structural template for the fabrication of ultralight, highly porous aeromaterials that decouple the architectural advantages of the network from the intrinsic chemical limitations of ZnO. Ultimately, advancing T-ZnO from empirical optimization to rational technological deployment requires predictive multiphysics computational frameworks capable of guiding the design of its complex functionality.
