How to better understand the influence of electromagnetic parameters on the absorbing properties of electromagnetic wave absorbers (EMAs) is an essential prerequisite for further synthesis and development of high‐performance EMAs. In this work, an improved wave cancellation theory is used as a guiding principle to prepare N‐doped carbon‐coated cobalt nanoparticles (Co@NC) using ZIF‐8@ZIF‐67 as the...
The combination of 2D magnetic nanosheets and mesoporous carbon with unique interfaces shows considerable prospects for microwave absorption (MA). However, traditional assembly procedures make it impossible to accurately manage the assembly of magnetic nanosheets in carbon matrices. Herein, a reverse strategy for preparing complex magnetic nanosheet cores inside carbon‐based yolk–shell structures...
Constructing the adjustable surface conductive networks is an innovation that can achieve a balance between enhanced attenuation and impedance mismatch according to the microwave absorption mechanism. However, the traditional design strategies remain significant challenges in terms of rational selection and controlled growth of conductive components. Herein, a hierarchical construction strategy and...
Functional nanomaterials as nanodrugs based on the self‐assembly of inorganics, polymers, and biomolecules have showed wide applications in biomedicine and tissue engineering.

Herein,...
Exploring photocatalysts to foster CO2 photoreduction into high value‐added chemicals is of great significance. Lead halide perovskites (LHPs) have recently been extensively investigated as photocatalysts, owing to their facile fabrication and prominent optoelectronic properties. However, the toxicity of lead and instability will hinder their future large‐scale applications. To address these challenges,...
Those responsible for the development of sonosensitizers are faced with a dilemma between high sonosensitization efficacy and good biosecurity that limited the development of sonodynamic therapy (SDT). Herein, inspired by the intriguing therapeutic features of SDT and the potential catalytic activity of graphene quantum dots, the potential of N‐doped graphene quantum dots (N‐GQDs) to act as a sonosensitizer...
In article number 2004867, Yiqin Shi, Guqiao Ding and co‐workers demonstrate the superior sonosensitization effect of N‐doped graphene quantum dots, which is believed to be 3–5 times higher than that of traditional sonosensitizers. More importantly, pyrrole N and pyridine N are believed to form catalytic centers in sonochemical processing of N‐doped graphene quantum dots. This knowledge is important...
The extremely complex structure of carbon‐based quantum dots (CQDs) greatly limits the understanding of the solid‐state photoluminescent mechanism of CQDs. In article number 2004621, Siwei Yang, Peng He, Guqiao Ding, and co‐workers summarize the current understanding of the solid‐state photoluminescent (PL) of solid‐state CQDs from the perspective of energy band theory and electronic transitions....
Carbon‐based quantum dots (CQDs), including spherical carbon dots and graphene quantum dots, are an emerging class of photoluminescent (PL) materials with unique properties. Great progress has been made in the design and fabrication of high‐performance CQDs, however, the challenge of developing solid‐state PL CQDs have aroused great interest among researchers. A clear PL mechanism is the basis for...
Although much attention has been paid to the exploration of highly active electrocatalysts, especially catalysts for hydrogen evolution reaction (HER), oxygen evolution reaction (OER) and oxygen reduction reaction (ORR), the development of multifunctional catalysts remains a challenge. Here, we utilize AuNi heterodimers as the starting materials to achieve high activities toward HER, OER and ORR....
While the development of AIE (aggregation‐induced‐emission) based fluorimetric probes for biological applications has been an active research area, probes with a ratiometric signal for biomolecular recognition have been rare. Here, a ratiometric AIE glyconanoparticle formed by the supramolecular assembly between a silole‐based AIEgen and fluorescent glycoprobes for the detection of amyloid β (Aβ)...
Ever since the discovery of graphene, increasing efforts have been devoted to the use of this stellar material as well as the development of other graphene‐like materials such as thin‐layer transition metal dichalcogenides and oxides (TMD/Os) for a variety of applications. Because of their large surface area and unique optical properties, these two‐dimensional materials with a size ranging from the...
