High‐efficiency electromagnetic (EM) wave (EMW)‐absorbing materials have attracted extensive scientific and technical interest. Although identifying the dominant EM loss mechanism in dielectric‐loss materials is indispensable, it is challenging due to a complex synergism between dipole/interfacial polarization and conduction loss. Modulation of defects and microstructures can be a possible approach...
Highly symmetrical and streamlined nanostructures possessing unique electron scattering, electron‐phonon coupling, and electron confinement characteristics have attracted a lot of attention. However, the controllable synthesis of such a nanostructure with regulated shapes and sizes remains a huge challenge. In this work, a peanut‐like MnO@C structure, assembled by two core–shell nanosphere is developed...
Fluorescent polymer particles have witnessed an increasing interest in recent years, owing to their fascinating physicochemical properties as well as wide‐ranging applications. In this review, the state‐of‐the‐art research progress of fluorescent polymer particles in the past five years is summarized. First, the synthesis protocols for fluorescent polymer particles, including emulsion polymerization,...
Although assembled hollow architectures have received considerable attention as lightweight functional materials, their uncontrollable self‐aggregation and tedious synthetic methods hinder precise construction and modulation. Therefore, this study proposes a bi‐ion synergistic regulation strategy to design assembled hollow‐shaped cobalt spinel oxide microspheres. Dominated by the coordination‐etching...
With the rapid advancements of portable and wearable equipment, high‐efficiency electromagnetic interference (EMI) shielding materials are highly entailed to eliminate radiated electromagnetic pollution. Herein, by assembling hexagonal SrFe12O19 flakes into a Ti3C2Tx MXene/MWCNT substrate, a magnetized Ti3C2Tx‐based film is successfully fabricated by a facile filtration approach. Carbon nanotubes...
Interface modification to minimize charge recombination and trapping for efficient charge transport is crucial for the performance of perovskite solar cells (PSCs). Herein, functionalized p‐type blue carbon dots (B‐CDs) are ventured as an interface passivation layer to enhance the efficiency and long‐term stability of all‐inorganic CsPbI2Br PSCs. It is found that first the blue carbon dots with abundant...
Electromagnetic (EM) wave absorption materials have attracted considerable attention because of EM wave pollution caused by the proliferation of electronic communication devices. One‐dimentional (1D) structural magnetic metals have potential as EM absorption materials. However, fabricating 1D core–shell bimetallic magnetic species is a significant challenge. Herein, 1D core–shell bimetallic magnetic...
