Intervertebral disc degeneration (IVDD) is a significant contributor to low back pain, characterized by excessive reactive oxygen species generation and inflammation‐induced pyroptosis. Unfortunately, there are currently no specific molecules or materials available to effectively delay IVDD. This study develops a multifunctional full name of PG@Cu nanoparticle network (PG@Cu). A designed pentapeptide,...
Intervertebral Disc Degeneration
In article number 2308167, Pooyan Makvandi, Yunlong Zhou, Aimin Wu, and co‐workers prepared a multifunctional metal polyphenol nanoparticle that exhibited the ability to escape lysosomal capture and effectively targeted mitochondria to scavenge excess reactive oxygen species. The results of in vitro and in vivo experiments showed that the nanoparticles retarded disc...
Low‐dimensional materials serving as photocatalysts favor providing abundant unsaturated active sites and shortening the charge transport distance, but the high surface energy readily causes the aggregation that limits their application. Herein, it is demonstrated that 2D covalent organic framework (COF) TpBD nanosheets are effective in the dispersion and stabilization of 0D Ni(OH)2. The COF precursor...
Hydrophobic ionogel has attracted much attention in underwater sensing as the artificial electronic skins and wearable sensors. However, when the low conductive ionogel‐based sensor works in the marine environment, the salty seawater weakens its sensing performance, which is difficult to recognize. Herein, a salt‐adaptively conductive ionogel with high submarine strain sensitivity is reported. Based...
Utilization of life‐like hydrogels to replicate synergistic shape/color changeable behaviors of living organisms has been long envisaged to produce robust functional integrated soft actuators/robots. However, it remains challenging to construct such hydrogel systems with integrated functionality of remote, localized and environment‐interactive control over synergistic discoloration/actuation. Herein,...
Aerogels have provided a significant platform for passive radiation‐enabled thermal regulation, arousing extensive interest due to their capabilities of radiative cooling or heating. However, there still remains challenge of developing functionally integrated aerogels for sustainable thermal regulation in both hot and cold environment. Here, Janus structured MXene‐nanofibrils aerogel (JMNA) is rationally...
Currently used wound dressings are ineffective. Hence, there is a need to develop introduce a high‐performance medicament with multiple functions including rapid hemostasis and excellent antibacterial activity to meet the growing worldwide demand for wound healing products. Here, inspired by the strong adhesion of mussels and the enzyme‐mimicking activity of nanometallic biomaterials, the authors...
Utilization of rewritable luminescent materials for secure information storage and delivery has long been envisaged to reduce the cost and environmental wastes. However, it remains challenging to realize a temporally/spatially controlled display of the written information, which is crucial for secure information encryption. Here, inspired by bioelectricity‐triggered skin pattern switching in cephalopods,...
Organic–inorganic halide perovskite solar cells (PSCs) have attracted tremendous attention in the photovoltaic field due to their excellent optical properties and simple fabrication process. However, the recombination of photogenerated electron–hole pairs at the interface severely affects the power conversion efficiency (PCE) of the PSCs. Herein, a monolayer of inverse opal SnO2 (IO‐SnO2) is synthesized...
The integration of highly luminescent CsPbBr3 quantum dots on nanowire waveguides has enormous potential applications in nanophotonics, optical sensing, and quantum communications. On the other hand, CsPb2Br5 nanowires have also attracted a lot of attention due to their unique water stability and controversial luminescent property. Here, the growth of CsPbBr3 nanocrystals on CsPb2Br5 nanowires is...
Flexible Supercapacitors
In article number 2102054, Tao Chen and co‐workers report an efficient strategy to suppress the self‐discharge behavior of flexible supercapacitors by building a heterogeneous polyanion/polycation electrolyte between two electrodes. The electrostatic repulsive effect between the charged polyelectrolytes and movable ions endows the charged supercapacitors with longer self‐discharge...
Supercapacitors with high power density and an ultralong cyclic lifetime have been intensively investigated. However, the crucial challenge of their rapid self‐discharge process is often neglected in most cases. A heterogeneous interface formed between two layers of polymer electrolytes is designed, in which a polyanion and a polycation are added into a common matrix of polymer electrolyte, respectively...
Thiolate‐protected nanoclusters with different charge states usually show similar structure frameworks but different electronic configurations, which are proved to dramatically affect their properties such as magnetism, photoluminescence, and catalytic activity. Until now, few nanoclusters with alterable charge states have been reported and only some of them are structurally solved, limiting the in‐depth...
In article number 2007122, Min Chao, Jincui Gu, Xun Wang, Tao Chen, and co‐workers present an advanced all‐in‐one separation membrane, which can realize continuous water purification with stable separation performance, catalytic degradation ability, antibacterial capacity and excellent self‐cleaning ability, suggesting its potential value for purifying realistic complex wastewater.
Membrane separation is recognized as one of the most effective strategies to treat the complicated wastewater system for economic development. However, serious membrane fouling has restricted its further application. Inspired by sphagnum, a 0D/2D heterojunction composite membrane is engineered by depositing graphitic carbon nitride nano/microspheres (CNMS) with plentiful wrinkles onto the polyacrylic...
Inspired by nature, diverse biomimetic hydrogel actuators are fabricated and become one of the most essential components of bionics research. Usually, the anisotropic structure of a hydrogel actuator is generated at the early fabrication process, only a specific shape transformation behavior can be produced under external stimuli, and thus has limited the development of hydrogel actuators toward the...
Tungsten oxide (WO3−x), a new alternative to conventional semiconductor material, has attracted numerous attentions owning to its widespread potential applications. Various methods have been reported for the synthesis of WO3−x nanostructures such as nanowires or nanodots. However, templates or surfactants are often required for the synthesis, which significantly complicate the process and hinder the...
Monodisperse AIE (aggregation‐induced emission)‐active conjugated polymer nanoparticles are synthesized by dispersion polymerization using geminal Suzuki cross‐coupling of 1,1‐dibromoolefins. The size of the nanoparticles can be adjusted by varying the concentration of the initial monomer.
