Abstract Although advances in wireless technologies such as miniature and wearable electronics have improved the quality of our lives, ubiquitous use comes at expense increased exposure to electromagnetic (EM) radiation. Up date, extensive efforts been made develop high-performance EM absorbers based on synthetic materials. However, design an absorber with both exceptional dissipation ability good environmental adaptability remains a substantial challenge. Here, we report class carbon...
Harvesting largely ignored and wasted electromagnetic (EM) energy released by electronic devices converting it into direct current (DC) electricity is an attractive strategy not only to reduce EM pollution but also address the ever-increasing crisis. Here we report synthesis of nanoparticle-templated graphene with monodisperse staggered circular nanopores enabling EM-heat-DC conversion pathway. We experimentally theoretically demonstrate that this nanoporous structure alters graphene's...

Abstract Two-dimensional (2D) superlattices, formed by stacking sublattices of 2D materials, have emerged as a powerful platform for tailoring and enhancing material properties beyond their intrinsic characteristics. However, conventional synthesis methods are limited to pristine sublattices, posing significant practical challenge when it comes chemically modified sublattices. Here we report chemical method that overcomes this creating unique graphene superlattice, with monodisperse,...
Abstract By dispersing magnetic materials within various nanoscale structural frameworks, a complex and weavable network of fields is created. This not only systematically reconstructs interactions with external electromagnetic but also inversely adjusts its properties, potentially leading to anomalous or enhanced behaviors. However, the challenges lie in finding an effective nano‐framework capable efficiently regulating flux lines visualizing these reconstructed at nanoscale. In this study,...

Abstract When interacting with an external Electromagnetic (EM) field, symmetric nanostructures, characterized by their periodic crystalline arrangement, typically resonate at specific frequencies. This resonance enhances local electromagnetic fields, leading to strong EM absorption, yet within a narrow absorption range. Conversely, asymmetric distinguished complex electric field polarization and distributions, provide broader frequency responses, albeit generally weaker loss across the...
