Nanoporous gold (NPG) is characterized by a bicontinuous network of nanometer-sized
metallic struts and interconnected pores formed spontaneously by oxidative dissolution of …

Mechanical metamaterials can be defined as a class of architected materials that exhibit
unprecedented mechanical properties derived from designed artificial architectures rather …

Most existing methods for additive manufacturing (AM) of metals are inherently limited to~ 20–
50 μm resolution, which makes them untenable for generating complex 3D-printed metallic …

Structural hierarchy can enhance the mechanical behavior of materials and systems. This is
exemplified by the fracture toughness of nacre or enamel in nature and by human-made …

Materials subjected to high dose irradiation by energetic particles often experience severe
damage in the form of drastic increase of defect density, and significant degradation of their …

A successful working model for nanoporosity evolution during dealloying was introduced 15
years ago. Since that time, the field has rapidly expanded, with research groups from across …

This study presents analysis on the vibration behavior of the two-dimensional functionally
graded (2D-FG) nano and microbeams which are made of two kinds of porous materials for …

Architected metals and ceramics with nanoscale cellular designs, eg, nanolattices, are
currently subject of extensive investigation. By harnessing extreme material size effects …

Monolithic nanoporous metals, derived from dealloying, have a unique bicontinuous
solid/void structure that provides both large surface area and high electrical conductivity …

This work firstly evaluated the microscale mechanical properties of sintered Ag, consisting of
various Ag particles of a flake shape and spherical shape from nano to micro size …
