The design and fabrication of novel carbon hosts with high conductivity, accelerated electrochemical catalytic activities, and superior physical/chemical confinement on sulfur and its reaction intermediates polysulfides are essential for the construction of high‐performance C/S cathodes for lithium–sulfur batteries (LSBs). In this work, a novel biofermentation coupled gel composite assembly technology...
The structural coexistence of dual rigid and mobile sublattices in superionic Argyrodites yields ultralow lattice thermal conductivity along with decent electrical and ionic conductivities and therefore attracts intense interest for batteries, fuel cells, and thermoelectric applications. However, a comprehensive understanding of their underlying lattice and diffusive dynamics in terms of the interplay...
mRNA therapy has shown great potential in infectious disease vaccines, cancer immunotherapy, protein replacement therapy, gene editing, and other fields due to its central role in all life processes. However, mRNA is challenging to pass through the cell membrane due to its significant negative charges and degradation from RNase, so the key to mRNA therapy is efficient packaging and delivery of it...
Nanotransducers
The microbial‐free bumblebee is a powerful tool to explore the precise control of engineered microbiota. Nanotransducers are fabricated to regulate the engineered bacteria inside the bumblebee gut by two spatiotemporal means, including magneto‐thermal and photothermal. This advanced technology lays the foundation for the treatment of bumblebee intestinal parasitic diseases and the...
Bumblebees are essential pollinators of wild‐flowering plants and crops. It is noticed that regulating the gut microorganisms of bumblebees is of great significance for the maintenance of bumblebee health and disease treatment. Additionally, social bees are used as models to study regulatory control methods of gut bacteria in vivo. However, these methods lack precision and are not studied in bumblebees...
The interface between the perovskite and electron‐transporting material is often treated for defect passivation to improve the photovoltaic performance of devices. A facile 4‐Acetamidobenzoic acid (containing an acetamido, a carboxyl, and a benzene ring)‐based molecular synergistic passivation (MSP) strategy is developed here to engineer the SnOx/perovskite interface, in which dense SnOx are prepared...
Low intrinsic conductivity and structural instability of MoS2 as an anode of sodium‐ion batteries limit the liberation of its theoretical capacity. Herein, density functional theory simulations for the first time optimize MoS2 interlayer distance between 0.80 and 1.01 nm for sodium storage. 1‐Butyl‐3‐methyl‐imidazolium acetate ([BMIm]Ac) induces cellulose oligomers to intercalate MoS2 interlayers...
Hierarchically ordered porous materials with tailored and inter‐connected macro‐, meso‐, and micro‐pores would facilitate the heterogeneous adsorption and catalysis processes for a wide range of applications but remain a challenge for synthetic chemists. Here, a general and efficient strategy for the synthesis of inverse opal metal–organic frameworks (IO MOFs) with a tunable size of macro‐, meso‐,...
Wide bandgap (WBG) perovskites through tuning iodine/bromine ratios are capable of merging with narrow bandgap organic bulk heterojunctions to construct tandem solar cells to overcome the Shockley–Queisser limitation. However, WBG perovskites readily suffer from light‐induced halide ion migration, leading to detrimental phase segregation and hence severe open‐circuit voltage (VOC) loss. Here, to solve...
Semiconductor chemiresistive gas sensors play critical roles in a smart and sustainable city where a safe and healthy environment is the foundation. However, the poor limits of detection and selectivity are the two bottleneck issues limiting their broad applications. Herein, a unique sensor design with a 3D tin oxide (SnO2) nanotube array as the sensing layer and platinum (Pt) nanocluster decoration...
Hypoxic Tumor Therapy
In article number 2200786, Lili Feng, He Ding, Piaoping Yang, and co‐workers develop a near‐infrared (NIR)–triggered nanoplatform with controlled release of a heat shock proteins (HSPs) inhibitor for synergistic mild photothermal and enhanced Fenton nanocatalysis. Upon NIR irradiation, gambogic acid is released and inhibits the expression of HSP90. Notably, the nanoplatform simultaneously...
Mild photothermal therapy (PTT, <45 °C) can prevent tumor metastasis and heat damage to normal tissue, compared with traditional PTT (>50 °C). However, its therapeutic efficacy is limited owing to the hypoxic tumor environment and tumor thermoresistance owing to the overproduction of heat shock proteins (HSPs). Herein, a near‐infrared (NIR)‐triggered theranostic nanoplatform (GA‐PB@MONs@LA)...
Artificial cells are a powerful platform in the study of synthetic biology and other valuable fields. They share a great potential in defining and utilizing the superiority of the living system. Here, a protein synthesis system based on thermal responsive hydrogels with porous structure is reported. The hydrogels can immobilize plasmids on the surface inside their porous structure through a volume...
Acute myeloid leukemia (AML) is the most common adult acute leukemia with very low survival rate due to drug resistance and high relapse rate. The C‐X‐C chemokine receptor 4 (CXCR4) is highly expressed by AML cells, actively mediating chemoresistance and reoccurrence. Herein, a chemically synthesized CXCR4 antagonistic peptide E5 is fabricated to micelle formulation (M‐E5) and applied to refractory...
This work is inspired by oysters converting worthless sand into precious pearls. In article number 2000553, Chen Wang and co‐workers present the “trash into treasure” process, which efficiently promotes antibacterial therapy and wound healing. The confinement effect of 2D Al‐metal–organic frameworks (MOFs) maintains gold nanoparticles (AuNPs) as ultrasmall without gathering and makes them exhibit...
As one of the common reactive oxygen species, H2O2 has been widely used for combating pathogenic bacterial infections. However, the high dosage of H2O2 can induce undesired damages to normal tissues and delay wound healing. In this regard, peroxidase‐like nanomaterials serve as promising nanozymes, thanks to their positive promotion toward the antibacterial performance of H2O2, while avoiding the...
Microcapsules consisting of hydrogel shells cross‐linked by glucosamine–boronate ester complexes and duplex nucleic acids, loaded with dyes or drugs and functionalized with Au nanoparticles (Au NPs) or Au nanorods (Au NRs), are developed. Irradiation of Au NPs or Au NRs results in the thermoplasmonic heating of the microcapsules, and the dissociation of the nucleic acid cross‐linkers. The separation...
In article number 1902086, Yanying Wang, Chunya Li, and co‐workers use ionic liquid–based Zn‐ metal–organic framework (MOF) as template for MoS2 nanoparticles synthesis, which are then carbonized to yield light‐responsive ZnS/C/MoS2 nanocomposites. ZnS/C/MoS2 nanocomposites can produce good photocurrent response under the excitation of visible light and are used as a photoactive element to construct...
A hexafluorophosphate ionic liquid is used as a functional monomer to prepare a metal–organic framework (Zn‐MOF).
