Limited by low conductivity,designing cathode materials with excellent electron transfer efficiency for high-performance nickel-zinc batteries （NZBs） remains *** this study,a series of bimetallic metal-organic nanowires were fabricated by doping M ions in NiNTA,resulting in NiMNTA (M=Mg2+,Mn2+,Co2+,Zn2+,Ag+),and NixCo6-xNTA （x=1,2,3,4,5）.The proportions and types of metal ions can be modified without altering the initial coordination structure.X-ray absorption fine structure spectroscopy （XAFS） revealed that only M–O bonds,not metal bonds,were present in the *** performance of Ni2Co4NTA as the cathode for aqueous NZBs was significantly improved,achieving the maximum energy density of 279.17Wh kg-1with the high cycle stability （retention rate of 72.0%after 1,000 cycles）.The flexible Ni2Co4NTA//Zn@carbon cloth battery employing gel electrolyte also exhibits the excellent Coulombic efficiency of 96%after 350 *** approach shows considerable potential for designing one-dimensional materials with bimetallic modifications,providing new strategies for developing cathode materials for NZBs with high specific capacity and cycle stability.

The full utilization of active metal sites is meaningful for enhancing the application of materials in the energy storage field. In this study, a nickel-based nanosphere（NiSA-SSA-Co） precursor was obtained via effective doping based on a dual-ligand complex. With thermal activation, the pore microstructure of the precursor was modulated, and a transition state complex（NiSASSA-Co-350） was fabricated. NiSA-SSA-Co-350 not only retains part of the framework structure, but also fully exposes the metal nodes and enhances the efficiency of the active sites. NiSA-SSA-Co-350 exhibits optimal conductivity and intrinsic reactivity when applied as an electrode material for nickel-zinc batteries（NZBs）. In contrast to the precursor, NiSA-SSA-Co-350with large specific surface area shows a higher specific capacity(0.30 mAh cm-2at 3 mA cm-2). This work hopefully provides a new perspective on the study of nanomaterial porosity in energy storage applications.

在土地的利用中,人们对土壤盐渍化的治理有着悠久的历史,因为土壤盐渍化治理困难、没有特效措施、治理工程量大,因此土壤盐渍化也被称为土地的"癌症"。近年来由于气候的改变、不合理耕作,次生盐碱化问题也在日益加重,大多数治理手段治标不治本,不能从根本上解决问题。经研究金合欢-檀香树联种模式能有效防治次生盐碱化、改良土壤的同时为农民带来较理想的经济效益。该模式利用金合欢的发达根系从深层土壤汲取水分,通过蒸腾作用有效控制地下水位,达到防治土壤返盐的作用;檀香树作为半寄生树种,扎根浅,必须要依附于金合欢树根系,二者的配合能够带来巨大的生态环境效益与经济效益。

Optoelectronic memristors have emerged as promising hardware platforms for highly efficient image perception owing to their low crosstalk, fast response, and low power consumption. However, the development of optoelectronic memristors with multi-wavelength recognition capabilities remains constrained by the limitations of their inherent bandgap. In this work, a multi-wavelength-modulated optoelectronic memristor that operates based on the localized surface plasmon resonance effect is developed using silver （Ag）-titanium dioxide （TiO2）/polymethyl methacrylate （PMMA） nanocomposites. The SET voltage can be gradually reduced by modulating the optical wavelength of visible irradiation. On this basis, reconfigurable IMP and False logic operations have been implemented in the memristive logic circuit. The neuromorphic visual preprocessing and recognition function for mixed-color patterns is demonstrated based on wavelength-dependent resistive switching behaviors. The proposed optoelectronic memristor enables high-density storage and in-memory computing.
