Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices
1 Introduction The growing demand for lightweight structural applications has drawn considerable attention to lattice materials that are known for their low densities and superior mechanical properties [1-4]. Triply periodic minimal surface (TPMS) shell lattices are a special class of lattice materials that can achieve a balance among open-cell features, exceptional mechanical properties, and superior multifunctionality [5-8].
Material‐Gradient Enabled Enhancement of Strength and Strain‐Hardening of Lattice Structures
1 Introduction Nature provides remarkable examples of optimized design through the strategic selection of compositional and functional gradients in both materials and structures.[1-4] Lattice structures, defined by their periodic cellular architecture, have emerged as a transformative class of metamaterials in modern engineering.[5, 6] These architected materials exhibit an exceptional combination of properties, including high strength,[7] stiffness,[8] and energy absorption,[9, 10] while...
Harnessing screw dislocations in shell-lattice metamaterials for efficient, stable electrocatalysts - Nature Communications
Abstract Developing highly active and robust catalysts remains a critical challenge for the industrial realization and implementation of nitrate reduction. Here, we proposed a screw dislocation-mediated three-dimensional (3D) printing strategy for scalable, integrated manufacturing of metamaterial catalysts.
Exploiting multiscale dynamic toughening in multicomponent alloy metamaterials for extreme impact mitigation
Abstract Mechanical metamaterials can unlock extreme properties by leveraging lightweight structural design principles and unique deformation mechanisms. However, research has predominantly focused on their quasi-static characteristics, leaving their behavior under extreme dynamic conditions, especially at length scales relevant to practical applications largely unexplored.
Oxide-dispersion-enabled laser additive manufacturing of high-resolution copper - Nature Communications
Abstract Laser additive manufacturing of pure copper (Cu) with complex geometries opens vast opportunities for the development of functional devices in microelectronics and telecommunication. However, laser additive manufacturing of high-resolution pure Cu remains a challenge. Here we report a facile oxide-dispersion-strengthening (ODS) strategy that enables additive manufacturing of Cu with sub-100 μm (~70 μm) resolution by laser powder-bed fusion.
Imperfection‐Enabled Strengthening of Ultra‐Lightweight Lattice Materials
1 Introduction Lightweight materials, characterized by low densities and superior stiffness and strength per unit mass, are crucial for modern engineering applications that demand increased material efficiency and fuel savings.[1, 2] At present, these materials are employed in diverse fields including medical, automotive, and aerospace engineering.[3, 4] One effective approach for weight reduction is incorporating various topological porosities into the materials.[5] Lattice materials, which...
