Stiff auxetics: Hierarchy as a route to stiff, strong lattice based auxetic meta-materials

Stiff, Strong, Zero Thermal Expansion Lattices via Material Hierarchy

For engineering applications where tight dimensional tolerances are required, or for applications where materials are subjected to a wide range of temperatures it becomes desirable to reduce a material’s coefficient of thermal expansion. By carefully designing lattice microstructures, zero thermal expansion can be achieved. This work describes lattice microstructures that achieve zero expansion...

Stiff person case misdiagnosed as conversion disorder: A case report

Background: Stiff person syndrome (SPS) is a rare neurological disease resulting in stiffness and spasm of muscles. It initially affects the axial muscles and then spread to limb muscles. Emotional stress exacerbated the symptoms and signs of the disease. The pathophysiology of the disease is caused by the decreased level of the glutamic acid decarboxylase (GAD) activity due to an autoantibody ...

Towards ultra-stiff materials: Surface effects on nanoporous materials

The quest for stiff, strong and tough hybrid materials: an exhaustive exploration.

How to arrange soft materials with strong but brittle reinforcements to achieve attractive combinations of stiffness, strength and toughness is an ongoing and fascinating question in engineering and biological materials science. Recent advances in topology optimization and bioinspiration have brought interesting answers to this question, but they provide only small windows into the vast design ...
