Editorial: Cutting-Edge Metastructures: Micro-Architected and Active Metamaterials

Resilient 3D hierarchical architected metamaterials.

Hierarchically designed structures with architectural features that span across multiple length scales are found in numerous hard biomaterials, like bone, wood, and glass sponge skeletons, as well as manmade structures, like the Eiffel Tower. It has been hypothesized that their mechanical robustness and damage tolerance stem from sophisticated ordering within the constituents, but the specific ...

Editorial: Cutting edge in systemic lupus erythematosus

The last 10 years have seen major advances in the understanding of the pathobiology of systemic lupus erythematosus (SLE). These improvements have led to discoveries of new molecules that target specific points in the immunological cascade that contribute to the immune hyperactivity and loss of tolerance in this heterogeneous autoimmune disease. Despite a large number of clinical trials assessi...

Highly-stretchable 3D-architected Mechanical Metamaterials

Soft materials featuring both 3D free-form architectures and high stretchability are highly desirable for a number of engineering applications ranging from cushion modulators, soft robots to stretchable electronics; however, both the manufacturing and fundamental mechanics are largely elusive. Here, we overcome the manufacturing difficulties and report a class of mechanical metamaterials that n...

Fabrication of 3d Micro-architected/ Nano-architected Materials

3D manufacturing of micro and nano- architected materials

Reducing mass without sacrificing mechanical integrity and performance is a critical goal in a vast range of applications. Introducing a controlled amount of porosity in a strong and dense material (hence fabricating a cellular solid) is an obvious avenue to weight reduction. The mechanical effectiveness of this strategy, though, depends strongly on the architecture of the resulting cellular ma...
