Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

Advanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Bifunctional nanoprecipitates strengthen and ductilize a medium-entropy alloy

Nature, 2021
Single-phase high- and medium-entropy alloys with face-centred cubic (fcc) structure can exhibit high tensile ductility1,2 and excellent toughness2,3, but their room-temperature strengths are low1-3. Dislocation obstacles such as grain boundaries4, twin boundaries5, solute atoms6 and precipitates7-9 can increase strength.

Deformation twinning in Ti48.9Zr32.0Nb12.6Ta6.5 medium entropy alloy

Materials Science and Engineering: A, 2021
Abstract The {112} β deformation twinning has never been confirmed in refractory high or medium entropy alloys (HEAs or MEAs) at room temperature. Here a Ti48.9Zr32.0Nb12.6Ta6.5 MEA shows {112} β twins was designed based on the d-electron alloy design method learned from β Ti alloys.

Shock-induced amorphization in medium entropy alloy CoCrNi

Scripta Materialia, 2022
Abstract We perform molecular dynamics simulations to investigate shock-induced amorphization in CoCrNi, a medium entropy alloy (MEA) and its mean-field variant without lattice distortion. We show that a critical velocity exists above which amorphization occurs. At a low shock velocity of 800 m/s, dislocation slip and twins dominate and amorphization
