Dynamically Modified Flexible Zn Powder Anodes with Stable Performance at High Rate and High Zn Utilization

open access: yesAdvanced Science, EarlyView.
A dynamically shape‐variant liquid metal‐based network is integrated into Zn powder electrode, where intrinsic fluidity and structural adaptability of the liquid metal‐based network enable effective mitigation of dendritic growth, alleviation of stress accumulation, and prevention of Zn loss during Zn plating‐stripping processes.

Effect of Precipitates on Dislocation Loops in Vanadium Alloy After Irradiation with 60 keV Deuterium Ions at Room Temperature

open access: yesMetals
The effect of different precipitates and nanoparticles on the distribution of radiation-induced dislocation loops in V-4Cr-4Ti alloy and V-4Cr-4Ti-1.8Y-0.4Ti3SiC2 alloy were studied. Both alloys were irradiated with 60 keV deuterium, and the distribution

Enhanced Mechanical Properties Via Boron‐Induced Multi‐Mechanism Strengthening in (NbTaTi1.5V)100‐xBx Refractory High Entropy Alloys

open access: yesAdvanced Science, EarlyView.
A trace amount of boron is introduced into NbTaTi1.5V RHEA, forming a finegrained BCC+TiO+TiB microstructure. The TiB phase generates numerous dislocations, strengthening the alloy. The alloy exhibits 3610 MPa compressive fracture strength and 1060 HV microhardness, while retaining 14.8% fracture strain.

Metal Ion‐Induced Fast Gelation of 2D MnO2 Nanosheets With Cationic Vacancies for Durable Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
We report Mn‐deficient aerogels by inducing the first gelation of MnO2 nanosheets in solution using divalent metal ions as crosslinking agents, thereby inhibiting nanosheet restacking and enhancing surface utilization. Benefiting from abundant Mn vacancies and 3D porous structures, the A‐MnO2 cathode exhibits improved conductivity, fast reaction ...
