Antimony selenide (Sb2Se3) is a highly promising photovoltaic material thanks to its outstanding optoelectronic properties, as well as its cost‐effective and eco‐friendly merits. However, toxic CdS is widely used as an electron transport layer (ETL) in efficient Sb2Se3 solar cells, which largely limit their development toward market commercialization. Herein, an effective green Cd‐free ETL of SnOx...
Control of structural ordering in noble metals is very important for the exploration of their properties and applications, and thus it is highly desired to have an in‐depth understanding of their structural transitions. Herein, through high‐pressure treatment, the mutual transformations between crystalline and amorphous phases are achieved in Pd nanosheets (NSs) and nanoparticles (NPs). The amorphous...
Nanotherapeutics for Spinal Cord Injury
In article number 2102102, Zhizhong Li, Tianfeng Chen, and co‐workers design a polymer‐based nano drug delivery system conjugating with MMPs‐responsive molecule to target the injury site, regulate the polarization of macrophages and exert neuroprotective effects to promote locomotor recovery.
Neuroinflammation is critically involved in the repair of spinal cord injury (SCI), and macrophages associated with inflammation propel the degeneration or recovery in the pathological process. Currently, efforts have been focused on obtaining efficient therapeutic anti‐inflammatory drugs to treat SCI. However, these drugs are still unable to penetrate the blood spinal cord barrier and lack the ability...
Multinary layered 2D nanomaterials can exhibit distinct physicochemical properties and innovative applications as compared to binary 2D nanomaterials due to their unique crystal structures. However, it still remains a challenge for the high‐yield preparation of high‐quality multinary 2D nanosheets. Here, the high‐yield and large‐scale production of two quaternary metal thiophosphate nanosheets are...
All‐purpose electrode materials (APEMs), which can be effectively available on not only alkali‐ion batteries but also emerging Li metal batteries, are urgently pursued to open up cost‐efficient tactics for practical application of energy storage systems (ESSs), but still remain challenging. Herein, the hierarchical porous carbon nanotubes network (NOPCT) with well‐tailored nanoarchitecture and high...
Construction of 2D transition metal dichalcogenide (TMD)‐based epitaxial heterostructures with different compositions is important for various promising applications, including electronics, photonics, and catalysis. However, the rational design and controlled synthesis of such kind of heterostructures still remain challenge, especially for those consisting of layered TMDs and other non‐layered materials...
For the first time Janus‐like films of surface‐acylated cellulose nanowhiskers (CNWs) with or without graphene oxide (GO) via one‐step evaporation‐driven self‐assembly process are reported, which have reconstructible time‐dependent micro‐/nanostructures and asymmetric wettability. The heterogeneous aggregation of CNWs on rough Teflon substrates favors the formation of uniform films, leading to hydrophobic...
In article number 2004922, Qiyun Tang, Kai Zhang, and co‐workers report Janus‐like films fabricated via the self‐assembly of surface‐acylated cellulose nanowhiskers (CNWs) with or without graphene oxide (GO). The obtained films with asymmetric topographies and properties on their top and bottom surfaces show different wettabilities and fast solvent‐responsive actuation. The self‐assembled patchy microspheres...
Antimony is an attractive anode material for sodium‐ion batteries (SIBs) owing to its high theoretical capacity and appropriate sodiation potential. However, its practical application is severely impeded by its poor cycling stability caused by dramatic volumetric variations during sodium uptake and release processes. Here, to circumvent this obstacle, Sb@C@TiO2 triple‐shell nanoboxes (TSNBs) are synthesized...
As an important aspect of crystal phase engineering, controlled crystal phase transformation of noble metal nanomaterials has emerged as an effective strategy to explore novel crystal phases of nanomaterials. In particular, it is of significant importance to observe the transformation pathway and reveal the transformation mechanism in situ. Here, the phase transformation behavior of face‐centered...
Hierarchical metal nanostructures containing 1D nanobuilding blocks have stimulated great interest due to their abundant active sites for catalysis. Herein, hierarchical 4H/face‐centered cubic (fcc) Ru nanotubes (NTs) are synthesized by a hard template‐mediated method, in which 4H/fcc Au nanowires (NWs) serve as sacrificial templates which are then etched by copper ions (Cu2+) in dimethylformamide...
Adoptive T lymphocyte immunotherapy is one of the most promising methods to treat residual lesions after glioma surgery. However, the fate of the adoptively transferred T‐cells in vivo is unclear, hampering the understanding of this emerging therapy. Thus, it is highly desirable to develop noninvasive and quantitative in vivo tracking of these T‐cells to glioma for better identification of the migratory...
Metasurface serves as a promising plasmonic sensing platform for engineering the enhanced light–matter interactions. Here, a hyperbolic metasurface with the nanogroove structure in the subwavelength scale is designed. This metasurface is able to modify the wavefront and wavelength of surface plasmon wave with the variation of the nanogroove width or periodicity. At the specific optical frequency,...
The deterioration of water resources due to oil pollution, arising from oil spills, industrial oily wastewater discharge, etc., urgently requires the development of novel functional materials for highly efficient water remediation. Recently, superhydrophilic and underwater superoleophobic materials have drawn significant attention due to their low oil adhesion and selective oil/water separation. However,...
Efficient and durable oxygen evolution reaction (OER) catalysts are highly required for the cost‐effective generation of clean energy from water splitting. For the first time, an integrated OER electrode based on one‐step direct growth of metallic iron–nickel sulfide nanosheets on FeNi alloy foils (denoted as FeNi3S2/FeNi) is reported, and the origin of the enhanced OER activity is uncovered in combination...
2D materials (TDMs) have been explored for photonic theranostics. To achieve deep‐tissue penetration, near‐infrared (NIR) light is essential for photoacoustic (PA) theranostics. However, because the absorption profiles of existing TDMs are generally featureless with no obvious NIR absorption peaks, their PA signals and therapeutic efficacies are limited. This paper herein reports the synthesis and...
Hierarchically porous carbons are attracting tremendous attention in sustainable energy systems, such as lithium ion battery (LIB) and fuel cell, due to their excellent transport properties that arise from the high surface area and rich porosity. The state‐of‐the‐art approaches for synthesizing hierarchically porous carbons normally require chemical‐ and/or template‐assisted activation techniques,...
