Surface triple junction matters in nanocrystal deformation
The high strength of nanostructured materials is usually attributed the size effect, i.e., the material becomes stronger as grain size and/or material thickness decreases to nanometer scale.
SYNL scientists predict thousands of topological phononic materials through computation and data driven strategy
Considering the current size of materials data, it is impossible to investigate each compound by trial-and-error experiments, which required labor-intensive efforts.
Three-dimensional atomic-resolution imaging of grain boundaries
The structure and behavior of grain boundaries, an important class of defects widely exist in materials, largely determine physical, chemical and mechanical properties of polycrystalline materials. For more than a century, the study of grain boundary structure and behavior has been a focus of materials science.
Scientists propose new strategy to design and synthesize high-efficiency non-precious metal catalysts for acetylene hydrogenation
Selective hydrogenation of acetylene is an essential step in petrochemical industry. Generally, a trace amount of acetylene (0.5%-2%) in ethylene must be removed by hydrogenation to avoid poisoning of the polymerization catalyst in the following process.
New Research Progress in Highly Efficient Hydrogen Peroxide Electrosynthesis on Nano-carbon Materials
Hydrogen peroxide (H2O2) is considered as one of the most important green oxidants for a wide range of industries, including wastewater treatment, papermaking and green chemical synthesis etc.
Strain Hardening in Metallic Glasses
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.
