Limited by low conductivity, designing cathode materials with excellent electron transfer efficiency for high-performance nickel-zinc batteries（NZBs） remains challenging. In this study, a series of bimetallic metal-organic nanowires were fabricated by doping M ions in Ni NTA, resulting in Ni MNTA(M = Mg~2+, 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 material. 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 cycles. This 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.

Increasing the thrust-weight ratio of aeroengines requires development of high-strength and stable high-temperature materials. A data-driven design of Ni-based turbine disc superalloys is performed to improve the yield strength to reach the target. Through first-principles calculations determining the design superalloy system, the theoretical models and Calculation of Phase Diagram (CALPHAD) screening compositions, and machine learning extrapolating prediction, 14 compositions are selected from 2,865,039 composition combinations. Ni-17Cr-8Co-1Mo-1W-6Al-3Ti-1Nb-1Ta is selected to verify the design accuracy. Experimental tests prove that the designed alloy has trade-offs of microstructure with satisfying design targets, and then, the yield strength is higher in the designed alloy than in commercial superalloys, reaching 728 MPa at 850 ℃. A scheme for increasing the performance of the designed alloy is proposed by discussing the strengthening mechanisms, machine learning process, and alloying chemistry effect. The cross-scale data-driven design is regarded as an accurate and efficient way to design novel high-strength Ni-based turbine disc superalloys, whose significance is the obvious reduction of trial-and-error tests.
