Dynamic photonic and thermal management with nano-architected materials (Invited Paper)

Nano-architected materials are promising for a range of applications due to their unique properties. In this talk, I will present our latest advances in the on-demand manufacturing of nano-architected materials through optothermal manipulation and bubble lithography. These advanced techniques allow for the precise engineering of nano-architectures, enabling in-situ optical measurements that reveal novel photonic behaviors and interactions. Drawing inspiration from nature, we have engineered nano-architected materials with outstanding passive radiative cooling capabilities. By leveraging machine learning, we have significantly accelerated their design, surpassing the constraints of natural evolution and achieving superior cooling efficiency. Furthermore, these materials have been seamlessly integrated into a silicon-based battery, enabling all-season dynamic radiative thermoregulation alongside electrical power generation. This multifunctional device presents a solution for developing energy-efficient buildings and reliable power systems.
