Gut microbiota function has numerous effects on humans and the diet humans consume has emerged as a pivotal determinant of gut microbiota function. Here, a new concept that gut microbiota can be trained by diet‐derived exosome‐like nanoparticles (ELNs) to release healthy outer membrane vesicles (OMVs) is introduced. Specifically, OMVs released from garlic ELN (GaELNs) trained human gut Akkermansia muciniphila...
Hierarchical architecture engineering is desirable in integrating the physical‐chemical behaviors and macroscopic properties of materials, which present great potential for developing multifunctional microwave absorption materials. However, the intrinsic mechanisms and correlation conditions among cellular units have not been revealed, which are insufficient to maximize the fusion of superior microwave...
The low ionic and electronic conductivity between current solid electrolytes and high‐capacity anodes limits the long‐term cycling performance of all‐solid‐state lithium‐ion batteries (ASSLIBs). Herein, this work reports the fabrication of an ultra‐stable electrode‐solid electrolyte composite for high‐performance ASSLIBs enabled by the homogeneous coverage of ultrathin Mg(BH4)2 layers on the surface...
Nature provides a successful evolutionary direction for single‐celled organisms to solve complex problems and complete survival tasks – pseudopodium. Amoeba, a unicellular protozoan, can produce temporary pseudopods in any direction by controlling the directional flow of protoplasm to perform important life activities such as environmental sensing, motility, predation, and excretion. However, creating...
In this work, ethanol oxidation reaction (EOR) via 12‐electron (C1‐12e) pathway on spiky Au@AuPd nanoparticles (NPs) with ultrathin AuPd alloy shells is achieved in alkaline media with the assistance of the near‐infrared (NIR) light. It is found that OH radicals can be produced from the OHads species adsorbed on the surfaces of Pd atoms led by surface plasmon resonance (SPR) effect of spiky Au@AuPd...
The charge recombination resulting from bulk defects and interfacial energy level mismatch hinders the improvement of the power conversion efficiency (PCE) and stability of carbon‐based inorganic perovskite solar cells (C‐IPSCs). Herein, a series of small molecules including ethylenediaminetetraacetic acid (EDTA) and its derivatives (EDTA‐Na and EDTA‐K) are studied to functionalize the zinc oxide...
Coatings for passive radiative cooling applications must be highly reflected in the solar spectrum, and thus can hardly support any coloration without losing their functionality. In this work, a colorful daytime radiative cooling surface based on structural coloration is reported. A designed radiative cooler with a bioinspired array of truncated SiO2 microcones is manufactured via a self‐assembly...
Superhard Nanocrystalline Cubic Silicon Carbide
In article number 2201212, Guoying Gao, Bo Xu, and co‐workers successfully synthesize nanocrystalline β‐SiC bulks with asymptotic Vickers hardness over the superhard threshold of 40 GPa, broadening the family of superhard materials. The frontispiece emphasizes the superhardness of nanocrystalline SiC bulk by scratching the cBN single crystal.
Superhard materials other than diamond and cubic boron nitride have been actively pursued in the past two decades. Cubic silicon carbide, i.e., β‐SiC, is a well‐known hard material with typical hardness <30 GPa. Although nanostructuring has been proven to be effective in enhancing materials’ hardness by virtue of the Hall–Petch effect, it remains a significant challenge to improve hardness of β‐SiC...
Annihilation of vacancy clusters in monolayer molybdenum diselenide (MoSe2) under electron beam irradiation is reported. In situ high‐resolution transmission electron microscopy observation reveals that the annihilation is achieved by diffusion of vacancies to the free edge near the vacancy clusters. Monte Carlo simulations confirm that it is energetically favorable for the vacancies to locate at...
Van der Waals materials composed of stacks of individual atomic layers have attracted considerable attention due to their exotic electronic properties that can be altered by, e.g., manipulating the twist angle of bilayer materials or the stacking sequence of trilayer materials. To fully understand and control the unique properties of these few‐layer materials, a technique that can provide information...
The electronic properties of stacked few‐layer 2D materials are highly dependent on their precise structural arrangement. In article number 2100388, featured on the front cover, Michael J. Zachman, Miaofang Chi, and co‐workers describe a four‐dimensional scanning transmission electron microscopy technique that utilizes interference between Bragg discs to enable high‐resolution mapping of picometer‐scale...
Poor deep tumor penetration and incomplete intracellular drug release remain challenges for antitumor nanomedicine application in clinical settings. Herein, a nanomedicine (RLPA‐NPs) is developed that can achieve prolonged blood circulation, deep tumor penetration, active‐targeting of cancer cells, endosome/lysosome escape, and intracellular selectivity self‐amplified drug release for effective drug...
In this study, a highly sensitive and self‐driven near‐infrared (NIR) light photodetector based on PdSe2/pyramid Si heterojunction arrays, which are fabricated through simple selenization of predeposited Pd nanofilm on black Si, is demonstrated. The as‐fabricated hybrid device exhibits excellent photoresponse performance in terms of a large on/off ratio of 1.6 × 105, a responsivity of 456 mA W−1,...
P‐type and n‐type top‐gate carbon nanotube thin‐film transistors (TFTs) can be selectively and simultaneously fabricated on the same polyethylene terephthalate (PET) substrate by tuning the types of polymer‐sorted semiconducting single‐walled carbon nanotube (sc‐SWCNT) inks, along with low temperature growth of HfO2 thin films as shared dielectric layers. Both the p‐type and n‐type TFTs show good...
A proper design of direct liquid phase exfoliation (LPE) for 2D materials as graphene, MoS2, WS2, h‐BN, Bi2Se3, MoSe2, SnS2, and TaS2 with common cosolvents is carried out based on considering the polar and dispersive components of surface tensions of various cosolvents and 2D materials. It has been found that the exfoliation efficiency is enhanced by matching the ratio of surface tension components...
