Aqueous zinc ion batteries have received unprecedented attention owing to their superior safety and sustainability, yet their cycling stability especially at high current rates is greatly limited by the poor reversibility of Zn metal anodes, due to the delayed ion transport, severe water‐induced side reactions, and uncontrollable dendrites growth at electrolyte/electrode interface. Herein, a robust and multi‐scale functionally designed amorphous ZnWO4 (ZWO) artificial interphase that fully addresses the aforementioned issues, is proposed. The modified Zn anodes deliver remarkable stability, surpassing 3000 h of operation at a high current density of 20 mA cm−2 in symmetrical cells. Even under harsh conditions of 20 mA cm−2 and 10 mAh cm−2, the electrode demonstrates steady cycling for over 600 h with low overpotential. The excellent cycling stability and rate performance are mainly attributed to a range of collective functionalities of ZWO interphase, including short‐range and isotropic ion migration, superior ion‐screening capability, and a thermodynamically enhanced energy barrier for hydrogen evolution reaction (HER) during Zn plating. These findings highlight the significance of the multi‐scale functional interphase in overcoming key barriers associated with zinc anodes under high current density, offering a facile and insightful approach for achieving high‐performance Zn metal anodes.

Marine microorganisms are increasingly recognized as primary producers of marine secondary metabolites, drawing growing research interest. Many of these organisms are unculturable, posing challenges for study. Metagenomic techniques enable research on these unculturable microorganisms, identifying various biosynthetic gene clusters (BGCs) related to marine microbial secondary metabolites, thereby unveiling their secrets. This review comprehensively analyses metagenomic methods used in discovering marine microbial secondary metabolites, highlighting tools commonly employed in BGC identification, and discussing the potential and challenges in this field. It emphasizes the key role of metagenomics in unveiling secondary metabolites, particularly in marine sponges and tunicates. The review also explores current limitations in studying these metabolites through metagenomics, noting how long‐read sequencing technologies and the evolution of computational biology tools offer more possibilities for BGC discovery. Furthermore, the development of synthetic biology allows experimental validation of computationally identified BGCs, showcasing the vast potential of metagenomics in mining marine microbial secondary metabolites.

Near‐infrared (NIR) phosphors converted light‐emitting diodes (NIR pc‐LEDs) are ideal NIR sources for versatile applications, which imply the practical significance in tailoring the emission of the NIR phosphors to enhance the performance for specific application. Herein, a paradigm of tailoring the emissions in a series of Cr3+‐doped phosphors to match the applications in NIR lighting, detection, and short‐wave infrared sources through combinatorial management of crystal‐field and energy transfer is presented. The emission band largely increases from 84 to 190 nm when the introduction of [MgO6]‐[GeO4] into Y3Ga5O12:0.08Cr3+ forms Y3MgxGa5‐2xGexO12:0.08Cr3+ through the substitution of [GaO6]‐[GaO4]. Such a large increase in width makes it suitable for near‐infrared lighting to near‐infrared detection. Moreover, the Yb3+, Nd3+ and Er3+ are doped to construct energy transfer with Cr3+, broadening the emission infrared region and enhanced thermal stability. An optimized Yb3+ emission dominates Y3Ga5O12:0.4Cr3+,Yb3+ phosphor has excellent thermal stability (129%@423 K) and is suitable for high‐power short‐wave infrared sources. The presented work not only provides a series of well‐performed NIR phosphors, but only lights up the avenue for designing the Cr3+ emission for specific application. [ABSTRACT FROM AUTHOR]

The nonlinear Hall effect (NLHE), as a new member of Hall effect family, has been realized in many materials, attracting a great deal of attention. Here, we report the observation of NLHE in magnetic topological insulator Sb-doped MnBi4Te7 flakes. The NLHE generation efficiency can reach up to 0.06 V−1, which is comparable to that observed in MnBi2Te4. Differently, the NLHE can survive up to 200 K, much larger than the magnetic transition temperature. We further study the scaling behavior of the NLHE with longitudinal conductivity. The linear relationship with opposite slope when temperature is below and above the magnetic transition temperature is uncovered. It reveals that the NLHE originates from skew scattering. Our work provides a platform to search NLHE with larger generation efficiency at higher temperatures. [ABSTRACT FROM AUTHOR]

Compared with conventional single-energy computed tomography (CT), dual-energy CT (DECT) provides better material differentiation but most DECT imaging systems require dual full-angle projection data at different X-ray spectra. Relaxing the requirement of data acquisition is an attractive research to promote the applications of DECT in wide range areas and reduce the radiation dose as low as reasonably achievable. In this work, we design a novel DECT imaging scheme with dual quarter scans and propose an efficient method to reconstruct the desired DECT images from the dual limited-angle projection data. We first study the characteristics of limited-angle artifacts under dual quarter scans scheme, and find that the negative and positive artifacts of DECT images are complementarily distributed in image domain because the corresponding X-rays of high- and low-energy scans are symmetric. Inspired by this finding, a fusion CT image is generated by integrating the limited-angle DECT images of dual quarter scans. This strategy enhances the true image information and suppresses the limited-angle artifacts, thereby restoring the image edges and inner structures. Utilizing the capability of neural network in the modeling of nonlinear problem, a novel Anchor network with single-entry double-out architecture is designed in this work to yield the desired DECT images from the generated fusion CT image. Experimental results on the simulated and real data verify the effectiveness of the proposed method. This work enables DECT on imaging configurations with half-scan and largely reduces scanning angles and radiation doses. [ABSTRACT FROM AUTHOR]
