Discovery of Layered Two-dimensional MoSi2N4 Family
Identifying two-dimensional layered materials in the monolayer limit has led to discoveries of numerous new phenomena and unusual properties.
CdPS3 Nanosheets-based Membrane with High Proton Conductivity Enabled by Cd Vacancies
Proton transport in nanochannels under humid conditions is crucial for the application in energy storage and conversion. However, existing materials, including Nafion, suffer from limited conductivity of up to 0.2 siemens per centimeter.
Strain-hardening and Suppression of Shear-banding in Rejuvenated Bulk Metallic Glass
Strain-hardening (the increase of flow stress with plastic strain) is the most important phenomenon in the mechanical behaviour of engineering alloys because it ensures that flow is delocalized, enhances tensile ductility and inhibits catastrophic mechanical failure.
Enhanced thermal stability of nano grained metals below a critical grain size
Refining grains of metals into the nanometer scale may greatly enhance their strength and hardness. But the introduced high density of grain boundaries provides a strong driving force for grain coarsening accompanied by property degradation.
Extra strengthening and work hardening in gradient nanotwinned metals
The gradient structures exist ubiquitously in the natural materials such as shells, bones and trees, and exhibit a high strength and a good toughness to help creatures survive from the natural damages. These ingenious gradient structures shed a light on developing the high performance metals through tailoring their microstructures.
