The recent groundbreaking achievement in the synthesis of large‐sized single crystal C60 monolayer, which is covalently bonded in a plane using C60 as building blocks. The asymmetric lattice structure endows it with anisotropic phonon modes and conductivity. If these C60 are arranged in form of 1D fiber, the improved manipulation of phonon conduction along the fiber axis could be anticipated. Here,...
Space charge transfer of heterostructures driven by the work‐function‐induced built‐in field can regulate the electronic structure of catalysts and boost the catalytic activity. Herein, an epitaxial heterojunction catalyst of CoO/Mo2C with interfacial electron redistribution induced by work functions (WFs) is constructed for overall water splitting via a novel top‐down strategy. Theoretical simulations...
Super‐Fast Fog Collectors
In article number 2301745, Jinlong Song and co‐workers develop a novel super‐fast fog collector based on self‐driven jet of mini fog droplets, which is hopefully to resolve the water crisis in some arid but foggy regions.
Freshwater scarcity crisis threatens human life and economic security. Collecting water from the fog seems to be an effective method to defuse this crisis. Nonetheless, the existing fog collection methods have the limitations of the low fog collection rate and efficiency because of their gravity‐based droplet shedding. Here, the aforementioned limitations are resolved by proposing a new fog collection...
The introduction of structural complexity to nanoparticles brings them interesting properties. Regularity breaking has been challenging in the chemical synthesis of nanoparticles. Most reported chemical methods for synthesizing irregular nanoparticles are complicated and laborious, largely hindering the exploration of structural irregularity in nanoscience. In this study, the authors have combined...
Bitten Gold Nanoparticles
Unprecedented bitten gold nanoparticles are produced through a combination of seed‐mediated growth and chemical etching. Each nanoparticle has an irregular nanocavity on it. The presence of an irregular nanocavity causes the bitten gold nanoparticles to exhibit strong single‐particle chiroptical responses. More details can be found in article number 2301476 by Jianfang Wang...
Photothermal‐Gas Synergistic Cancer Therapy
In article number 2206749, Benhui Hu, Yun Liu, and co‐workers propose a cascade reaction‐promoted CO release strategy to realize augmented photothermal‐gas synergistic cancer therapy. Gold‐based porphyrinic coordination polymer nanosheets synthesized by a simple aqueous phase reaction, with ultrasmall zero‐valent gold as the coordination node, have the advantages...
As a gasotransmitter, carbon monoxide (CO) possesses antitumor activity by reversing the Warburg effect at higher concentrations. The targeted delivery of carbon monoxide‐releasing molecules (CORMs) using nanomaterials is an appealing option for CO administration, but how to maintain CO above the threshold concentration in tumor tissue remains a challenge. Herein, a nanozyme‐catalyzed cascade reaction...
Point defects of heteroatoms and vacancies can activate the inert basal plane of molybdenum sulfide (MoS2) to improve its performance on catalyzing the hydrogen evolution reaction (HER). However, the synergy between heteroatoms and vacancies is still unclear. Here, a chemical vapor deposition‐assisted in situ vanadium (V) doping method is used to synthesize monolayer MoS2 with abundant and tunable...
2D Semiconductors are promising in the development of next‐generation photodetectors. However, the performances of 2D photodetectors are largely limited by their poor light absorption (due to ultrathin thickness) and small detection range (due to large bandgap). To overcome the limitations, a strain‐plasmonic coupled 2D photodetector is designed by mechanically integrating monolayer MoS2 on top of...
Porous and hollow carbon materials have great superiority and prospects in electrochemical energy applications, especially for surface charge storage due to the high active surface. Herein, a general strategy is developed to synthesize mesoporous hollow carbon spheres (MHCS) with controllable texture and compositions by the synergistic effect of dopamine polymerization and metal catalysis (Cu, Bi,...
The immunosuppressive tumor microenvironment (TME) can significantly limit the immunotherapeutic effects of the PD‐L1 antibody (aPDL1) by inhibiting the infiltration of CD8+ cytotoxic T cells (CTLs) into the tumor tissues. However, how to reprogram the immunosuppressive TME and promote the infiltration of CTLs remains a huge challenge for aPDL1 to achieve the maximum benefits. Herein, the authors...
Nanoparticulate drug delivery systems (nano‐DDSs) are required to reliably arrive and persistently reside at the tumor site with minimal off‐target side effects for clinical theranostics. However, due to the complicated environment and high interstitial pressure in tumor tissue, they can return to the bloodstream and cause secondary side effects in normal organs. Recently, a number of nanogatekeepers...
High energy density is the major demand for next‐generation rechargeable batteries, while the intrinsic low alkali metal adsorption of traditional carbon–based electrode remains the main challenge. Here, the mechanochemical route is proposed to prepare nitrogen doped γ‐graphyne (NGY) and its high capacity is demonstrated in lithium (LIBs)/sodium (SIBs) ion batteries. The sample delivers large reversible...
γ‐Graphyne is a nanostructured carbon allotrope with unique large conjugate rings that are composed by sp and sp2 hybridized carbon atoms. In article number 1804710, Xiaoli Cui and co‐workers synthesize γ‐graphyne via a facile mechanochemical approach and demonstrate its excellent reversible Li+ storage performance experimentally.
γ‐Graphyne is a new nanostructured carbon material with large theoretical Li+ storage due to its unique large conjugate rings, which makes it a potential anode for high‐capacity lithium‐ion batteries (LIBs). In this work, γ‐graphyne‐based high‐capacity LIBs are demonstrated experimentally. γ‐Graphyne is synthesized through mechanochemical and calcination processes by using CaC2 and C6Br6. Brunauer–Emmett–Teller,...
Using magnetomechanical force to kill cancer cells has attracted great attention recently. This study presents novel hedgehog‐like microspheres composed of needle‐like magnetic nanoparticles with carbon and gold double shells. Using a novel low‐frequency vibrating magnetic field (VMF), these microspheres with sharp surfaces can seriously damage cancer cells and strongly inhibit mouse tumor growth...
